Eating with food allergies is a challenge whether you’re an adult or a child – and some adults underestimate the psychological impact food allergies have on children. According to a current study, children with food allergies are more anxious than other children and might refrain social events where food is served to refrain feeling “different”.

Food Allergies in Children: A Source of Anxiety?

Researchers in Italy found that children with food allergies are more anxious and socially isolated than their peers who are allergy-free. When there’s a social event, children who have allergic reactions to foods are forced to bring along food they can safely take – or not take at all. This makes children with food allergies anxious and uncomfortable at a time when it’s so important to “fit in”.

When Italian researchers studied the social habits of 107 young allergy-sufferers, they found 17% of them don’t go to events where food is served, while another 1 in 4 take their own food to an event. Not surprisingly, children who have allergic reactions to food worry about having a life-threatening anaphylactic reaction if they’re accidentally exposed to a food their allergic to. Eating becomes a scary proposition for them.

Many children with food allergies carry an epinephrine pen everywhere they go to reverse the effects of an anaphylactic reaction should one occur. If they forget their pen or don’t have swift access to it, they have the very real risk of dying should a serious anaphylactic reaction occur. It’s lots of a stress for any child to have to deal with.

Are There Ways to Help Kids With Food Allergies Feel Less Stress?

Purchase some cookbooks designed for people with allergies, and make some allergy-safe treats at home for your child to enjoy. If your child is reluctant to go to a celebration where they’ll have to bring along their own food, host a celebration in your home and serve foods that are innocuous for your child.

Accentuate to your child that life doesn’t revolve around food and what they can or can’t take – and it’s okay to go to a celebration and enjoy being with other children without intake the same things they eat. Help your child realize that other children have medical issues such as diabetes, seizures or allergies and that it shouldn’t define who they are.

But whatever they do, make sure your child is safely equipped with an epinephrine pen. It could save their life.

Medical News Today. “Food Allergies in Kids Cause Anxiety and Loneliness, Have Dramatic Impact on Their Quality of Life”

Food allergies are a common problem in kids. Almost two million kids have food allergies in the United States. Some food allergies are life threatening, even if the food is taken in very tiny quantity. Peanut tops the list of notorious foods which cause allergies. Following it are milk, especially cow’s milk, soy, eggs, wheat, seafood and other nuts.

Food allergies are caused when the immune system is confused. The job of the immune system is to protect the body from diseases, bacteria, viruses and germs. The antibodies produced by the immune system helps to fight these minute external organisms which makes the mortal sick. But if the body is allergic to certain food, the immune system mistakes the food to a harmful foreign substance and takes action towards it thinking that it is hazardous to the body. The body acts adversely, when it isn’t supposed to do so.

When the immune system detects allergic substance, the antibodies produce mast cells. They are a kind of immune system cell which release a chemicals, such as histamine, in the bloodstream. These chemicals affect the respiratory system, digestive system, nose, eyes, throat, and skin. Initial symptoms are runny nose, tingling sensation in the lips or tongue, and itchy skin rash like hives. The reaction can be mild to severe and depends on each individual. The symptoms can appear right after the food is consumed or after few hours. Other symptoms are cough, wheezing, nausea, hoarse voice, vomiting, diarrhea, stomach ache, and throat tightness.

A sudden and harsh allergic reaction is known as anaphylaxis. The patient encounters many problems, all at once which involve blood vessels, the heart, digestion, breathing, and skin. The blood pressure drops very steeply, the tongue swells and there is swelling in the breathing tubes. Patients who have such allergic reactions should be ready to handle emergencies. They should always carry some type of medicine which will help to combat or reduce the adverse affect of the food.

Most of the times, it is very simple to detect the cause of food allergy. Problems such as hives start to surface as soon as the child eats the substance he is allergic to. At other times, it becomes very difficult to determine the cause of allergy. In such cases, everything should be observed under close surveillance. Food items which are prefabricated out of many ingredients should be thoroughly checked for the allergic cause. Most of the times, allergies are inherited from other family members or other kids born with food allergies. Changes in the surroundings and the body play a major role in these kinds of cases. Some of the kids aren’t actually allergic to the food and show only mild reaction. Like people who are disaccharide intolerant suffer from diarrhea and belly pain after consuming milk and diary products. This is not an indication that the child is allergic to milk. This reaction happens because their body is incapable of breaking down the sugars which are found in diary products and milk.

If the conditions are severe, a physician should be consulted immediately. If food allergy is diagnosed, the physician refers to an allergy specialist. The physician asks questions like intake patterns, past allergic reactions and the time period between the consumption of food and the surfacing of the symptoms. The specialist can also ask about allergy related conditions like asthma or eczema and whether allergic reactions are hereditary. Usually skin test and blood test is done to test the antibodies and the reaction they have on the skin when it is exposed to the allergic substance.  

Kids who are allergic to egg and milk outgrow them as the age progresses. But allergies which are severe and are related to items such as peanut, shrimps, and some kind of fish, last for a lifetime. Other than food, kids can be allergic to certain medicines and flower pollen. The ideal way to refrain allergies is to refrain the cause of it. No specific medicine has been developed for the cure of allergies.

INTRODUCTION

Food allergy is recognized as a common worldwide problem, and, like other atopic disorders, its incidence seems to increase. In the past years, investigations of allergic food proteins and related immunological responses have moved to the molecular level, and the newly-found knowledge might wage novel experimental strategies for the work diagnosis and the immuno-modulatory control of food-induced allergic reactions (1, 2).

Approximately 20% of the population alters their diet for a perceived adverse reaction to food, but the application of double-blind placebo-controlled oral food challenge, the “gold standard” for diagnosis of food allergy, shows that questionnaire-based studies overestimate the prevalence of food allergies. The clinical disorders determined by adverse reactions to food can be classified on the basis of immunologic or no immunologic mechanisms and the organ system or systems affected (3, 4, 5).

The true prevalence of food allergy is lower and seems to range from 1% to 4% of the general population and about 6% of the general population and about 6% of the paediatric population, but does occur in as much as 25% of kids with eczema6. Allergic hypersensitivity simply put, is an adverse immune reaction to a accelerator (or allergen) in our environment, which is normally harmless to the non-allergic person. It might present as mild itching of the skin, tissue swelling and wheezing or even progress to full-blown anaphylaxis and death. 18 million allergy sufferers live in the UK where 4% of the populations also have a food allergy.

Allergy develops after repeated exposure to the causative allergen. Sensitization takes place on initial exposure (a process that might take up to six weeks to develop) and no adverse reaction appears to occur during initial sensitization (6).

(A) DEFINITION

A food allergy is an immunologic response to a food accelerator and caused by allergens in the food that are a kind of accelerator in the food. These proteins resist the cooking process, the acid in the stomach and the enzymes in the stomach and intestines and enter the blood stream and they cause the allergy reaction after they enter the blood stream.

(B) SIGNS AND SYMPTOMS

Symptoms of food allergies are: -

1. Anaphylaxis: – a severe, whole-body allergic reaction that can result in death. Leads to vasodilation and, if severe, symptoms of life-threatening shock.

2. Angioedema: – rapid swelling (edema) of the skin, mucosa and submucosal tissues, especially of the eyelids, face, lips, and tongue.

3. Eczema is a form of dermatitis, or inflammation of the upper layers of the skin.

(a). Atopic eczema (aka infantile e., flexural e., atopic dermatitis) is believed to have a hereditary component, and often runs in families whose members also have hay fever and asthma. Itchy rash is particularly noticeable on grappling and scalp, neck, inside of elbows, behind knees, and buttocks.

(b). Contact dermatitis is of two types: allergic (resulting from a delayed reaction to some allergen, such as poison ivy or nickel), and irritant (resulting from direct reaction to a solvent, for example). Some substances act both as allergen and irritant (e.g. wet cement). Other substances cause a problem after sunlight exposure, bringing on phototoxic dermatitis.

(c). Xerotic eczema (aka asteatotic e., e. craquele or craquelatum, winter itch, pruritus hiemalis) is dry skin that becomes so serious it turns into eczema. It worsens in dry winter weather, and limbs and trunk are most often affected. The itchy, tender skin resembles a dry, cracked, river bed. This disorder is very common among the older population.

(d). Seborrhoeic dermatitis (aka cradle cap in infants, dandruff) causes dry or greasy scaling of the scalp and eyebrows. Scaly pimples and red patches sometimes appear in various adjacent places. In newborns it causes a thick, yellow crusty scalp rash called cradle cap which seems related to demand of biotin, and is often curable.

4. Skin rashes, such as nettle rash (also called urticaria or hives). Some of these longer lasting rashes are called atopic dermatitis. 

5. Itching of the mouth, throat, eyes, skin, or any area

6. Nausea, vomiting, diarrhoea, stomach cramps, or abdominal pain

7. Running nose or nasal congestion

8. Wheezing, scratchy throat, shortness of breath, or difficulty swallowing

9. Mood swings, depression: The symptoms of an Immunoglobulin E (IgE) allergic reaction can take place within a few minutes to an hour. The process of intake and digesting food affects the timing and location of a reaction. IgG reactions build over a period of hours to days, and therefore symptoms can be difficult to notice as allergy-related (7). 

 TYPES OF ALLERGENIC FOOD

There are a number of groups of foods that are responsible for causing the majority of food allergies (6).  Rice allergy is more common in East Asia where rice forms a massive part of the diet.  In Central Europe, celery allergy is more common. The top allergens vary somewhat from country to country but milk, eggs, peanuts, tree nuts, fish, shellfish, soy, wheat and sesame tend to be in the top ten in many countries (8).

The most common food allergies are: –

1. Milk allergy:-

Two out of a hundred infants under one year old suffer from cow’s milk allergy, making it the most common food allergy of childhood. In general kids lose this sensitivity as they grow up with nine out of ten losing it by the age of three; it is uncommon for adults to suffer from this allergy. Symptoms are frequently vomiting and diarrhoea in children, with 30-50% also having skin rashes of some type. A small number of kids have an anaphylactic reaction to milk which tends to be life-long.

The major allergens in milk are the caseins and the accelerator b-lactoglobulin. People are usually allergic to more than one kind of milk protein. The proteins from cow’s milk are very similar to those from goats and sheep. Thus goat’s or sheep’s milk can't be used as a cow’s milk substitute in allergic individuals (8). 

A report about 22-year-old Female patient is described who was repeatedly hospitalised on statement of severe asthmatic attacks presumably due to the ingestion of cow’s milk or milk-containing products. There were no signs of gastrointestinal disturbance, but some urticaria and angioedema occurred. Strongly positive RASTs (radioallergosorbent test) were observed in the blood serum against the proteins in cow’s milk, bovine serum, egg white, cod fish, and home dust. The symptoms were successfully controlled by rigorous dietary measures (8). 

2. Eggs:-

Allergy to eggs is usually observed in young kids rather than adults, and like cow’s milk allergy, fades with time. Occasionally kids suffer from a severe form of allergy which is not outgrown.

The main allergens are the egg white proteins ovomucoid, ovalbumin, and ovotransferrin. The eggs of other poultry, such as ducks, are very similar to those of hens and can cause reactions in egg-allergic individuals (8). 

3. Peanut allergy:-

Peanuts are one of most allergenic foods and frequently cause very severe reactions, including anaphylaxis. Allergy to peanuts is established in childhood and usually maintained throughout life. Peanut allergy can be so severe that only very tiny amounts of peanut can cause a reaction. Thus the traces of nuts found in processed oils, or the carryover of materials on utensils used for serving foods, can be enough in some individuals, to cause a reaction. The main allergens in peanuts and Soya are the proteins used by the seed as a food store for it to grow into a seedling. One of the allergens in Soya bean is very similar to a major allergen from dust mites, a common environmental allergen. We aren’t sure yet whether this means there is a link between dust allergy and Soya allergy.

A massive number of kids who develop peanut allergy have their first reaction the first time they are given a peanut-containing product (usually a apply of peanut butter). A massive number of kids who develop peanut allergy have their first reaction the first time they are given a peanut-containing product (usually a apply of peanut butter). Peanut accelerator could pass into breast milk Twenty-three lactating women; aged 21 to 35 years ate 50 grams of dry roasted peanuts (about 60 peanuts or 1/3 cup). Breast milk samples were collected at hourly intervals. Peanut accelerator was found in the breast milk of 11 of the mothers. In 10 mothers, it was detected within two hours after she ate peanuts, in one mom it was detected six hours later.

That peanut accelerator is secreted into breast milk, thus sensitizing the baby who is at risk for developing an allergy. This might explain why up to 85 percent of kids have a peanut allergy reaction the first time they take a peanut-containing product. A baby born into a family with allergies.

[Note: - Milk, eggs, and wheat have previously been shown to pass into breast milk. The moms from allergic families eliminate peanuts and tree nuts (e.g., almonds, walnuts, etc.) and think about eliminating eggs, milk, fish, and perhaps other foods from their diets while nursing. If you select to do this, be sure to talk with a registered dietitian to be sure your diet is well-balanced (8).

4. Tree Nut Allergy:-

This group includes true tree nuts, such as Brazil nuts, hazelnuts, walnut and pecan. Whilst not as intensively studied as peanuts, indications are that tree nuts can cause symptoms as severe which can occasionally be fatal. Kids who become sensitised to tree nuts tend to remain allergic throughout life. Hazelnut and almond allergies are more like those people get to fruit, and are linked to pollen allergies. Nut allergens can be both destroyed by, and resistant, to cooking and we think that roasting might actually create new allergens. The allergens can be the seed storage proteins, or other molecules which are also found in pollen.

5. Fish and shellfish allergy:-

Allergies to shellfish are uncommon in children, mostly being experienced by adults. Reactions to fish are found in kids and adults. The incidence of seafood allergy is higher in those countries with a high consumption of fish and shellfish. Severe reactions are more frequently found with these foods, including anaphylaxis. Cooking does not destroy the allergens in fish and shellfish, and some individuals maybe allergic to the cooked, but not raw, fish. The major allergens in fish are flesh proteins called parvalbumins which are very similar in all kinds of fish. Shellfish allergens are usually found in the flesh and are part of the muscle accelerator system, whilst in foods such as shrimps, allergens have also been found in the shells.

If pregnant or trying to be, refrain seafood and shellfish. Some believe that it might cause your child to develop food allergy.

6. Fruits allergy:-

In general allergic reactions to fruits and vegetables are mild, and are often limited to the mouth, and are called the oral-allergy syndrome (OAS). Around four out of ten people having OAS are also allergic to tree and weed pollens. Thus people who are allergic to birch pollen are much more likely to be allergic to apples. There allergens in fruits and vegetables are not as complicated as other foods. Many of them are very like the allergens in pollens, which is why people with pollen allergies are also allergic to certain fruits.

Many fruit allergens are destroyed by cooking, and thus cooked fruits are often innocuous for fruit allergic people to eat. Allergies to latex gloves, especially amongst health professionals, are increasing. As many of the latex allergens are like those found in certain tropical fruits, such as bananas, these people can get an allergic reaction to handling or intake these foods (8). Tomato Allergy: - Reported on four cases (two adults with throat constriction, one child with gastro esophageal reflux disease [GERD], one child with atopic dermatitis) with IgE-mediated reactions to tomatoes.

Using extracts prepared from the skin, seeds, and fleshy fruit of the tomato, specific IgE antibody in the sera of patients was detected by ELISA. After characterizing the extracts for their antigen profile and reactivity with IgE, proteins were separated by SDS-PAGE (sodium dodecyl sulfate-polyacrylamide gel electrophoresis). Of the four patients, one adult showed higher IgE against tomato skin extract. Western blot tests of the patient’s scrum with tomato skin extract also revealed reaction with a accelerator band in the 42-45kD region. Tomato allergy can be manifested as atopic dermatitis, laryngeal angioedema, and even gastroesophageal reflux.

7. Cereals allergy:

Suffered by kids and adults alike, wheat allergy appears to be particularly associated with exercise-induced anaphylaxis. The more of a cereal (wheat, rye, barley, oats, maize or rice) we take the more likely we are to suffer an allergy. Thus rice allergy is found more frequently in populations intake ethnic diets. Seed storage proteins (such as wheat gluten) and other proteins present in grain to protect it from attack by moulds and bacteria, have been found to be major allergens.

8. Penicillin’s allergy reaction:

Frequently manifestations are – rash, itching, urticaria and fever. Wheezing, angioneuritis, edema, serum sickness and exofolliative dermatitis are less common. Anaphylaxis is rare but might be fatal. Fear of anaphylactic shock has several restricted the use of injPnG in general practice.  All form of penicillin (natural or semi synthetic) can cause allergy but it is more commonly seen after parenteral administration.

 Penicillin produce hypersensitivity – urticaria, angioedema, bronchiospasm, anaphylaxis or serum sickness. If early reaction had been only a rash, penicillin might be given cautiously – often no untoward effect is seen. History of penicillin allergy must be elicited before injection it. A scratch test on intradermal test (with 2 – 10 u ) might be performed first. On occasion, his it has caused fatal anaphylaxis. Testing with benzyl-penicilloyl – polylysine is safer. However a negative intradermal test does not rule out delayed hypersensitivity. It should also be released that presence of antibodies to penicillin does not mean allergy to it, because practically everyone who receives penicillin develop antibodies to it.

For the development of antibodies, penicillin or a product of it (mostly penicilloyl moiety – major determent) act as a hapten. Topical use of penicillin is highly sensitizing (contact dermatitis and other reaction). Therefore, all topical preparation of penicillin (including eye ointment) have been banned, except for use in eye as solution in case of gonococcal opthalmia (9).

CLASSIFICATION OF FOOD ALLERGY

B. Nonhereditary: – Induced (contact dermatitis), rare, involving respiratory and cutaneous systems

Portal of entry: Intact oral, and buccal mucosa, and skin causes: Foods, essential oils of foods and spices (10).

PATHOPHYSIOLOGY

A food allergy is an immunologic response to a food accelerator Food allergy is type 1 hypersensitivity reaction. Type I Hypersensitivity is characterised by excessive activation of mast cells and basophils by IgE, resulting in a systemic inflammatory response that can result in symptoms as benign as a runny nose, to life-threatening anaphylactic shock and death.

Exposure to an allergen activates B cells to form IgE secreting plasma cells   . The secreted IgE Molecules bind to IgE specific Fc Receptor on mast cells. Second Exposure to allergen leads to cross linking of the bound IgE triggering release of pharmacologically active mediators vasoactive amines (11).

Immunoglobulin E (IgE):

The potent biological activity of IgE granted it to be identified in serum despite its extremely low average serum concentration (0.3microgram/ml).IgE antibodies mediate the immediate hypersensitivity reaction that are responsible for the symptoms of hay fever, asthma, hives and anaphylactic shock. When the appropriate antigen was later injected at the same site, a wheal and flare reaction developed there .this reaction, called the p-k reaction was the basis for the first biological assay for IgE activity.

IgE binds to Fc receptors on the membranes of blood basophils and tissue mast cells, Cross-linkage or receptor bound IgE molecules by antigen (allergen) induces basophils and mast cells to translocation their granules to the plasma membrane and release their contents to the extracellular environment, a process known as degranulation.  As a result, a variety of pharmacologically active mediators are released and given rise to allergic manifestations.

Fc Receptors:

Many cells feature membrane glycoproteins called Fc receptors (FcR) that have an affinity for the Fc portion of the antibody molecule.  These receptors are essential for many of the bioligocal functions of antibodies.  An FcR binds IgE like: – The cytoplasmic domains of the chains of FcRI are associated with accelerator tyrosine kinase (PTKs). Crosslinkage of the FcRI receptors activates the associated PTKs, resulting in the phosphorylation of tyrosines within the ITAMs of the subunit as well as phosphorylation of residue on the  subunit and on phospholipace C.  These phosphyrylation events incduce the producton of a number of second messengers that mediate the process of degranulation.

Within 15 s after crosslinkage of FcRI, methylation of various membrane phospholipids is observed, resulting in an increase in membrane fluidity and the formation of Ca2+ channels.  An increase of Ca2+ reaches a peak within 2 min. of FcRI crosslinkage.  This increase is due both to the uptake of extracellular Ca2+ and to a release of Ca2+ from nitracellular stores in the endoplasmic reticulum.  The Ca2+ increase eventually leads to the formation of arachidonic acid, which is converted into two classes of potent mediators: prostaglandins and leukotrienes.  The increase of Ca2+ also promotes the assembly of microtubules and the contraction of microfilaments, both of which are necessary for the movement of granules to the plasma membrane.  The importance of the Ca2+ increase in mast-cell degranulation is highlighted by the use of drugs, such as disodium cromoglycate (cromolyn sodium), that block this influx as a treatment for allergies (11).

Concomitant with phospholipid methylation and Ca2+ increase, there is a transient increase in the activity of membrane-bound adenylate cyclase, with a rapid peak of its reaction product, cyclic adenosine monophosphate (cAMP), reached about one min. after crosslinkage of FcRI.  The effect of cAMP is exerted through the activation of cAMP-dependent accelerator kinases, which phosphorylate proteins on the granule membrane, thereby changing the permeability of the granules to water and Ca2+.  The consequent swelling of the granules facilitates their fusion with the plasma membrane, releasing their contents.  The increase in cAMP is transient and is followed by a drop in cAMP to levels below baseline.  This drop in cAMP appears to be necessary for degranulation to proceed; when cAMP levels are increased by certain drugs, the degranulation process is blocked.  Histamines are the main mediator of food allergy (11).

IgE Crosslinkage Initiates Degranulation

The biochemical events the mediate degranulaton of mast cells and blood basophils have many features in common.  For simplicity, this section presents a general overview of mast-cell degranulation mechanisms without calling attention to the slight differences between mast cells and basophils.  Even though mast-cell degranulation generally is initiated by allergen crosslinkage of bound IgE, a number of other stimuli can also initiate the process, including the anaphylatoxins (C3a, C4a, and C5a) and various drugs.  This section focuses on the biochemical events that follow allergen crosslinkage of bound IgE as follows

 Receptor Crosslinkage

IgE-mediated degranulation begins when an allergen cross links IgE that is bound (fixed) to the Fc receptor on the surface of a mast cell or basophil.  In itself, the binding of IgE to FcRI apparently has no effect on a target cell.  It is only after allergen crosslinks the fixed IgE-receptor complex that degranulation proceeds.  The importance of crosslinkage is indicated by the inability of monovalent allergens, which can't crosslink the fixed IgE, to trigger degranulation.

Genetic basis

There is much evidence to support the genetic basis of allergy, as allergic parents are more likely to have allergic children, and their allergies are likely to be stronger than those from non-allergic parents. However some allergies are not consistent along genealogies with parents being allergic to peanuts, but having kids allergic to ragweed, or siblings not sharing the same allergens. Ethnicity has also been shown to play a role in some allergies. Interestingly, in regard to asthma, it has been suggested that different genetic loci are responsible for asthma in people of Caucasian, Hispanic, Asian, and African origins. It has also been suggested that there are both general atopy genes and tissue-specific allergy genes that target the allergic response to specific mucosal tissues. Potential disease associated alleles include both coding region variation and SNPs. Caucasian people seem to have the most asthma (11).

DIAGNOSIS OF FOOD ALLERGY

Diagnosis of food allergy is based on clinical history, skin prick tests, and     work tests to detect serum-food specific IgE, elimination diets and challenges (12).

1. History: – The physician interviews the patient to determine if the facts are consistent with a food allergy. . The physician asks such questions as: What was the timing of the reaction? Did the reaction come on quickly, usually within an hour after intake the food? Was treatment for allergy successful? For example, if hives stem from a food allergy, antihistamines should relieve them. Is the reaction always associated with a certain food? Did anyone else get sick? For example, if the mortal has ingested fish contaminated with histamine, everyone who ate the fish should be sick. In an allergic reaction, however, only the mortal allergic to the fish becomes ill. 

2. Dietary Diary: – To keep a record of the contents of apiece meal and whether reactions occurred that are consistent with allergy. The dietary diary provides more details than the oral history, so that the physician and patient can superior determine if there is a consistent relationship between a food and the allergic reactions.

3. Elimination Diet: – The next step is an elimination diet. The patient does not take a food suspected of causing the allergy, for example, eggs, and substitutes another food, in this instance, another source of protein. If after the patient removes the food, the symptoms go away, the physician nearly always can make a diagnosis of food allergy. This technique is also not suitable if the allergic reactions have been infrequent13.

4. Skin Prick Tests: – The skin prick is simple to do and results are acquirable in minutes. Different allergists might use different devices for skin prick testing. Some use a “bifurcated needle”, which looks like a fork with two prongs. Others use a “multi-test”, which might look like a small board with several pins sticking out of it (14).

In a scratch-the-skin test, a dilute extract of the suspected food is place on the skin of the forearm or back. This portion of the skin then is scratched with a needle and observed for swelling or redness, which would signify a local allergic reaction to the food. A positive scratch test indicates that the patient has the IgE that is specific for the food being tested on the skin’s mast cells. In some highly allergic patients, however, especially if they have had anaphylactic reactions, skin tests should not be done because they could make another hazardous reaction. Skin tests also can't be done in patients with extensive eczema (13).

It is good for swiftly learning if a mortal is allergic to a particular food or not, because it detects allergic antibodies known as IgE. Skin tests can't predict if a reaction would occur or what kind of reaction might occur if a mortal ingests that particular allergen. They can however confirm an allergy in light of a patient’s history of reactions to a particular food. This nearly painless procedure grants the tested accelerator to interact with food-specific IgE on the surface of skin mast cells (12).

A device, such as a lancet, plastic probe or tip of a small gauge needle, is pressed through a commercial extract of food and a positive (histamine) and negative (saline-glycerine) controls into the epidermis. Allergens eliciting within 15 min a wheal at least 3 mm larger than that produced by the negative control are considered positive, indicating the possibility that the patients have symptomatic reactivity to the specific food, with strongly positive results implying a greater likelihood of clinical reactivity. When evaluating allergy to fruits and vegetables, commercially prepared extracts are often inadequate because they are prone to degradation, and therefore the fresh food might be used for prick-by-prick test. A number of investigators have analyzed the use of the “atopy patch test” in addition to skin prick test for the diagnosis of non-IgE-mediated food allergy, with delayed reactions to food, but at this time, there are no standard reagents or methods of application and interpretation. Thus, its diagnostic accuracy remains still controversial, especially in older kids (12).

In Eosinophilic gastroenteritis associated with food allergy and bronchial asthma. A skin prick test and RAST (radioallergosorbent test) to causative food allergens showed a negative result. A fiber-optic endoscopic biopsy from the gastric mucosa showed an intense eosinophilic infiltration. The fiber-optic endoscopic biopsy might be needed to refer coexisting EG if an allergic patient with blood eosinophilia complains of severe gastrointestinal symptoms (14).

5. Blood Tests:- Blood tests such as the RAST (radioallergosorbent test) and the ELISA (enzyme-linked immunosorbent assay). These tests measure the presence of food-specific IgE antibodies in the blood of patients, but they cost more than skin tests, and the results are not acquirable immediately (13).

In RAST, blood is drawn and sent to a work for testing to determine “predictive values” for certain foods. These predictive values can be compared to the RAST blood test results. If a person’s RAST score is higher than the predictive value for that food, then there is over a 95% chance the mortal will have an allergic reaction (limited to rash and anaphylaxis reactions) if they ingest that food. Currently, predictive values are acquirable for the following foods: milk, egg, peanut, fish, soy, and wheat. Blood tests grant for hundreds of allergens to be screened from a single sample, and cover food allergies as well as inhalants. However, non-IgE mediated allergies can't be detected by this method. Blood testing methodologies currently acquirable that can measure antibodies of IgG are not acceptable as a method of allergy evaluation. IgG-type anitbodies are not implicated in food allergy reactions15.

(A)       In vitro IgE food allergen-specific assays:-

The in vitro IgE assay is less sensitive, however, then the epicutaneous skin test. The in vitro IgE assay uses the same commercial food extract16.

1. Redioallergosorbeny (RAST):- The first test using this new technology was the redioallergosorbent test (RAST). The first step requires coupling the allergen (e.g., cow’s milk protein) to solid support (e.g., a paper disk). When this disk is place in a test tube with patient serum, the coupling of antibodies directed against milk or that were anti- cow’s milk in nature (this includes IgE, M, A, or E class) occurs. After washing, the third  step is the addition of radio-labelled (I125) rabbit antihuman IgE antibodies .these antibodies will attach themselves only to the IgE antimilk antibodies( which in turn are coupled to the cow’s milk accelerator in the paper disk). Then the amount of emission can be measured, and thus the amount of cow’s milk-allergen-anti-IgE cow’s milk antibody can be quantities (16).

2. Enzyme-Linked Immunosorbent Assay (ELISA) :- This is more current type of test, but is just like the RAST test except for two factors. First, allergen is usually coupled to the inner surface of small plastic walls (into which the patient’s serum and other ingredients of the test are placed). The second, and more important, difference is the final decimal factor. In the ELISA system, an enzyme coupled to the antihuman IgE denatures a substrate, which either change color or becomes fluorescent. Then the amount of color or fluorescence can be measured(16).

 (B) The production of interferon-gamma in response to a major peanut allergy, Ara h II correlates with serum levels of IgE anti-Ara h II.

To analyze the potential role of T cells in the pathogenesis of peanut allergy. Peripheral blood mononuclear cells (PBMCs) from patients with peanut allergy, patients with asthma, and nonatopic normal control subjects were assessed for proliferation after stimulation with a 17 kd major peanut allergen (Ara h II), ovalbumin, casein, soy, and Candida albicans. That Ara h II and C. albicans induced significantly higher levels of proliferation than ovalbumin, casein, and soy. Because interferon-gamma (IFN-gamma) and interleukin-4 (IL-4) play critical roles in IgE regulation, the production of these cytokines after stimulation with C. albicans and Ara h II. C. albicans stimulated similar levels of IFN-gamma in all three study groups. In contrast, after stimulation with Ara h II, culture supernatants from PBMCs of subjects with peanut allergy contained significantly lower levels of IFN-gamma than did the PBMCs of the two control groups (p = 0.02). More important, there was a significant (p = 0.05) inverse correlation between the serum IgE anti-Ara h II levels and IFN-gamma production by PBMCs from the respective peanut-allergic patients. IL-4 accelerator was not detected in culture supernatants of PBMCs stimulated with Ara h II. However, increment of cytokine gene transcripts by polymerase chain reaction did demonstrate IL-4 expression in Ara h II-stimulated PBMCs from both patients with peanut allergy and control subjects. Conclusion is that the level of IFN-gamma production in response to Ara h II might be an important bourgeois in determining the development of peanut-specific IgE responses (17).

(6). Other Laboratory Tests:- When evaluating patients with gastrointestinal symptoms, suspecting food hypersensitivities, a number of other standard work studies might be useful. Patients with allergic eosinophilic esophagitis and allergic eosinophilic gastroenteritis have peripheral eosinophilia, and patients with severe allergic eosinophilic gastroenteritis might have anaemia, blood in the stool, and decreased serum protein, albumin and IgG levels (with preservation of IgM and IgA). Endoscopy and biopsy are the most definitive approaches for diagnosing many of the gastrointestinal food hypersensitivities and might help the differential diagnoses. Greater than 10-20 eosinophils per 40 × high-power field in the esophagus is diagnostic of allergic eosinophilic esophagitis, especially if the pH probe is normal and there is demand of responses to antireflux medication. Eosinophils are normally present in the gastric and intestinal mucosa, and therefore eosinophil number must be greater to make the diagnosis of allergic eosinophilic gastroenteritis.

(7). Food Challenge:- The double-blind, placebo-controlled oral food challenge (DBPCFC) with gradually increasing amounts of the suspected food under attending over hours or days, is considered the “gold standard” test for the diagnosis of food allergy.

 In this test, various foods, some of which are suspected of inducing an allergic reaction, are place in individual opaque capsules. Both the patient and the physician are blinded, so that neither of them knows which capsules contain the suspected allergens. (Another medical mortal prepared the capsules.) The patient swallows a capsule and the physician then observes whether an allergic reaction occurs. This process is repeated with apiece capsule. The advantage of a food challenge is that if the patient has an allergic reaction only to the suspected foods and not to the other foods tested, the diagnosis of food allergy is confirmed. Just as with a rechallenge after the elimination diet and with the skin tests, however, someone having a history of severe reactions should not be tested with a food challenge because of the danger of inducing another severe reaction. In addition, this procedure is costly because it is difficult and requires a lot of time, especially for patients with multiple food allergies. Consequently, double-blind food challenges are done infrequently (13.)

Hypotension might occur in about 15% of these challenges, especially in patients affected by acute IgE-mediated reactions, enterocolitis syndrome, and severe atopic dermatitis, and therefore intravenous hydration therapy and supplies for resuscitation should be immediately acquirable (12).

Genetic Basis for Food Allergy

The R576 allele occurred with less frequency in nonatopic subjects than in patients with food allergy. Investigation of the prevalence of the glutamine to arginine (Q to R) mutation at position 576 of IL4R alpha (a position formerly shown to segregate with atopy) was conducted in 22 patients with a history of adverse food reactions, positive skin tests, and/or RAST. Eleven patients had positive food challenges. This was compared with a reference group of 57 nonatopic subjects.

In food allergy patients, allele frequency of the Q576 was 68% (30/44) and of the R576 was 32% (14/44), compared with 81% (92/114) and 19% (22/114) in the control group. Half of the patients (11) carried the R576 allele, 13% (3) of whom were homozygous, compared with prevalence in the general population of 20%. The high occurrence of the R576 allele in atopic patients was associated with a susceptibility to food allergy. Atopy, in general, has been known to be genetically determined, yet evidence for a genetic link to specific allergies has been lacking. This study demonstrates a significant association between the Q576R allele and the development of food allergy. Extension of this work might lead to a specific test for prediction of food allergy (13).

TREATMENT OF FOOD ALLERGY

(A). ORAL DESENSITIZATION & TOPICAL TREATMENT:- Various medications can wage relief for certain aspect of food-induced disorders. The primary therapy for food allergy is to refrain the responsible food.1 Only two specific treatments are acquirable to the allergic patient – allergen rejection and allergen-specific immunotherapy (SIT) given either orally or by injection (13).

(1). Treatment for Milk Allergies:-  It is total rejection of milk proteins. Initially if the infants are breastfed, the lactating moms are given an elimination diet. If symptoms are not relieved or if the infants are formula-fed, milk substitute formulas are used to wage the infant with a complete source of nutrition. Milk substitutes include hypoallergenic formulas based on hydrolyzed accelerator (such as nutramigen, alimentum, and pregestemil) or free amino acids. Soy milk should not be used in milk accelerator allergy as there is a 40-50% rate of cross-antigenicity of soy and cow protein.

(2.) Treatment for Nut allergy:-  It is usually treated with an exclusion diet and vigilant rejection of foods that might be contaminated with tree nuts or nut particles and/or oils. The most severe nut allergy reaction is called anaphylaxis and is an emergency situation requiring immediate attention and treatment with Epinephrine.

(3).Treatment for fruits allergy:- An OAS (Oral Allergy Syndrome) sufferer should refrain foods to which they are allergic. Peeling or cooking the foods have shown to reduce the effects of the allergy in the throat and mouth, but might not relieve reactions in the gastrointestinal tract. Antihistamines might also relieve the symptoms of the allergy. Persons with severe reactions might think about carrying injectable medication (such as an EpiPen) to relieve themselves if necessary. Allergy immunotherapy has improved or cured OAS in many patients.

(4).Antihistamines:- The older sedating type antihistamine tablets or syrup such as Piriton will reduce itching especially at night. Newer long acting anti-histamines such as Cetirizine have also evidenced to be very good for reducing skin inflammation if used for extended periods of up to 6 months.22 Antihistamines might partially relieve oral allergy syndrome and IgE-mediated skin symptoms, i.e. itching and rash, but they do not block systemic reactions (12).

(5).Cortisone or Steroid:- Systemic corticosteroids are generally effective in treating chronic IgE-mediated disorders (atopic dermatitis). A course of corticosteroids can be used to reverse severe inflammatory symptoms, but the side effects of protracted use are unacceptable. These produce rapid relief and are used for short periods to settle eczema flare-ups. They might also be used for longer periods when diluted in an emollient in which case treatment should be tapered off slowly. However, their long-term use might lead to thinning of the skin. Cortisone tablets or injections are very rarely, if ever, used in eczema (11).

(6). Sublingual Immunotherapy – the procedure:- Grazax oral paper desensitisation immunotherapy is now acquirable for adults as a treatment for grass pollen induced hay fever and allergic rhino-conjunctivitis.  This oral treatment is called Sublingual Immunotherapy or SLIT.  Each paper contains an extract of Timothy Grass (Phleum Pratense) 75000SQ-T.  The procedure is very innocuous and far less likely than injection immunotherapy to cause any adverse reaction (SLIT side-effects include headache and oral itching). The treatment involves taking one paper regular and allowing it to dissolve under the tongue over one minute before swallowing.  Treatment should commence two months before the grass pollen season and continued throughout the grass pollen season for maximal benefit. The treatment is stopped in the autumn/winter and then recommences two months prior to apiece subsequent grass pollen season (11).

(7). Emollients:- These skin moisturising creams and ointments, the mainstay of eczema treatment, are absolutely innocuous and should be applied liberally at least three or more times per day to hydrate and protect the skin. Different emollients include Emulsifying Ointment (HEB), White Soft Paraffin, Aqueous cream (UEA), Diprobase or Lipobase with Cetomacrogol, Epaderm, and Oilatum cream. Sometimes coal tar is applied to treat thickened skin. Oilatum Plus is an excellent bath emollient. Aveeno is an meal based emollient for very dry skin while Balneum is Soya oil based11.

(8). Wet Wraps:- These are applied at night to keep moisture in the skin, aid absorption of creams and to protect against scratching. First of all, emollients and steroid creams are applied to the eczematous areas. Elasticated cotton-based tubular dressings are soaked in luke-warm water and then cut to size so that they cover the affected areas. These can be applied overnight to the limbs, trunk, neck and even grappling (holes are cut in the dressing to grant apertures for eyes, ears, nose and mouth). This treatment is highly successful for severe weepy eczema, which is non-responsive to emollients and steroid creams.

(9). Other Therapies:- Evening Primrose oil (or gamolenic acid) has been tried with minimal success in the past.  Extracts of Chinese herbal teas seem to reduce inflammation even though they are quite unpalatable.  Tacrolimus (Protopic) and Pimecrolimus (Elidel) cream has just become acquirable and results so far have been very encouraging, even though chronic use has been associated with skin cancers in animals (11).

Multicenter Study of Emergency Department Visits for Food Allergy  

This study showed that even though guidelines exist for the emergency management of food allergy, “adherence to these guidelines appears low (18).

Prevention

The high-risk infants (both parents and siblings atopic) be exclusively breast-fed, that lactating moms refrain peanuts and nuts to refrain sensitization through breast milk, that the introduction of solid be delayed until six mo of age, and major allergens, such as peanuts, nuts and seafood, be introduced after three years of age (11).

(B) VACCINES, IMMUNOTHERAPY & INJECTION:-

If the food is accidentally ingested and a systemic reaction occurs, then epinephrine (best delivered with an autoinjector of epinephrine such as an Epipen) or Twinject should be used. It is doable that a second dose of epinephrine might be required for severe reactions (14). Epinephrine is the mainstay of treatment for anaphylaxis. Intramuscular injection grants more efficient absorption than the subcutaneous route (12).                                                                                                                                                                                                                                                                                                                                                                                                        

Novel therapies for IgE-mediated food allergy have been evaluated. Subcutaneous injections of humanized IgG anti-IgE antibodies (TNX-901), that recognize and mask an epitope in the CH3 region of IgE responsible for the binding to the high affinity Fc epsilon receptor I (FC?RI) on basophils and mast cells, for the treatment of patients affected by peanut allergy, showed a long-term increase in the average amount of peanut tolerated, but 25% of subjects showed no improvement.

Another anti-IgE preparation (Omalizumab) has been approved for the treatment of continual allergic asthma in patients who are poorly controlled with inhaled corticosteroids, but has not yet been evaluated for its efficacy in treating patients with peanut allergy. Theoretically, anti-IgE antibody therapy should be conserving against multiple food allergens, even though it would have to be administered indefinitely to maintain its conserving effects. Other immunotherapeutic strategies include use of engineered proteins lackink IgE-binding sites, immunomodulatory sequences being effective in reversing IgE-mediated sensitization, and engineered chimeric molecules forming complexes with allergen-specific IgE bound to mast cells and basophils, inhibiting their functions.

Some current studies suggested that probiotics, commonly defined as live micro organisms (bacteria from the genera Lactobacillus, Bifidobacterium, Escherichia, Enterococcus, Bacillus and Saccharomyces), administered in sufficient amounts, which confer a beneficial health effect on the host, might be useful in the treatment and prevention of food allergy. They might wage maturational signals for the gut-associated lymphoid tissue, equilibrise the generation of pro- and anti-inflammatory cytokines, reduce the dietary antigen load by degrading and modifying macromolecules, reverse the increased intestinal permeability, characteristic of kids with food allergy, normalization of the gut microecology, and enhance specific IgA responses frequently defective in kids with food allergy. Among the therapeutic option, currently under investigation, there are peptide immunotherapy, traditional Chinese medicine, mutated accelerator immunotherapy, DNA immunization, and immunization with immuno stimulating sequences (ISSs) and anti-immunoglobulin E (anti-IgE) Therapy. These novel forms of treatment for allergic disease hold promise for the innocuous &effective treatment of food allergic individuals & the prevention of food allergy in the future.

Traditional therapies:-

Although injection immunotherapy has traditional been employed in the treatment of inhalant allergies, such as allergic rhinitis, it has also been used with success in the treatment of food allergy when a young child was successfully to fish. In patient with allergic rhinitis experiencing oral allergy syndromes with the ingestion of cross-reacting allergens in fruits, nut, & vegetables,  traditional injection immunotherapy has been also been successful in many cases in ameliorating the oral allergy symptoms with minimal adverse reaction. Traditional injection immunotherapy for food allergy is currently not suggested because of the allergic side effects of the therapy. Studies have been conducted of a double-blind, placebo-controlled trial of rust immunotherapy for the treatment of anaphylactic hypersensitivity to peanuts. Patients in the treatment group were healthy to tolerate increased amounts of peanuts in post-treatment food challenges. The actual peanut immunotherapy produced so many side effects of treatment that it would be practically impossible to perform on a routine basis.

While food desensitization in the oral allergy syndrome has been generally successful & well tolerated with cross-reacting pollen immunotherapy. The practice of injection immunotherapy for food allergy has been largely abandoned, due to the associated risk of serious systemic reaction. Since Traditional immunotherapy has been largely impractical for the treatment of most food allergies, several noval therapies are being explored13.

Sodium cromoglycate in a dosage of 800 mg a day for 1 week, or a single dose of 1.0 g by mouth, did not block any of the reactions. By inhalation it blocked the asthmatic reactions which developed within a few sec of challenge (19).

(c).COMPLEMENTARY TREATMENTS OF FOOD   ALLERGY:-

1. Enzyme Potentiated Desensitization:- It involves mixing the alleged allergen with beta-glucuronidase (a common enzyme in the body) and applying it to the skin in very low doses. It has been used to treat hay fever and alleged food allergies. Double blind studies have unsuccessful to show any significant benefit with this regime (13).

2. Ionization:- Ionizing machines emit negative electric charges into the air, and this supposedly causes airborne allergens to cluster and start to the ground. These machines have been claimed to help hay fever and asthma sufferers by decreasing the allergen load on the nasal mucosa and lungs.

3. Ozone Therapy:- In treating allergy is a new addition to complementary medical treatment. The allergic patient’s blood be exposed to ozone gas and then re-injected or ozone is directly insufflate rectally or vaginally. This practice could have serious adverse results, as ozone is a very well documented trigger for allergy and asthma.

4. Homeopathy:- It is based on the law of similar – “like cures like”. Treatments are usually individualized for the specific patient and not the disease. But a well designed study published in the Lancet by Reilly and Taylor from Glasgow(4) did however show significant improvement in hay fever symptoms, as did Kleijnen’s review of clinical trials in homeopathy published in the.

5. Acupuncture:- Acupuncture is an ancient Chinese form of treatment that involves inserting tiny needles into specific meridians or areas of the body A small but temporary improvement in wheezing when acupuncture was employed.

6. Herbal medicine:- An herbal cure such as the Ma Huang plant (Ephedra sinica) which contains ephedrine has been used to treat asthma for 5000 years. One recently noted exception is the use of traditional Chinese herbal tea in the treatment of atopic eczema. Ling zhi (Reishi Mushroom) is another orient herbal preparation with steroid like properties used to treat allergies. Butterbur has been advocated in hay fever.

7. Nampudripad’s Allergy Elimination Technique (NAET):- It consists of combination of discredited methods of diagnosing and treating allergy such as kinesiology, Vega testing and acupuncture. The premise is that allergy contrary to our current understanding, is due to some form of internal energy blockage triggered by abnormal energy fields in the brain and Nampudripad proposed that after 20 or so treatments she can reprogram the brain and body energy flow and eradicate all allergies and many other diseases affecting mankind. However the whole issue of energy flow and electrical fields in the body being the cause of allergies has not ever been proven13.

MEDICINE – HERB/FOOD INTERACTIONS

Herbs and Foods Might Lead to Complications If You Take Them with Drugs. Herbs and foods might interact with medications you normally take that result in serious side reactions. It is always a good practice to tell your physician or health practitioners what you are taking so that they can advise you of doable complications, if there is any. You should also keep an eye for uncommon symptoms. Very often, this might foretell the symptoms of a drug interaction (19). Experts recommend that natural does not mean it is absolutely safe. Everything you place in your mouth has the potential to interact with something else. The medication that is taken by mouth travels through the digestive system in much the same way as food and herbs taken orally do. So, when a drug is blended with food or another herb, apiece can alter the way the body metabolizes the other. Some drugs interfere with the body’s capability to absorb nutrients. Similarly, some herbs and foods can lessen or increase the impact of a drug (20).

Alcohol is a drug that interacts with nearly each medication, especially antidepressants and other drugs that affect the brain and nervous system. Some dietary components increase the risk of side effects. Theophylline, a medication administered to treat asthma, contains xanthines, which are also found in tea, coffee, chocolate, and other sources of caffeine. Consuming massive amounts of these substances while taking theophylline increases the risk of drug toxicity. Certain vitamins and minerals impact on medications too. Massive amounts of broccoli, spinach, and other green leafy vegetables high in vitamin K, which promotes the formation of blood clots, can counteract the effects of heparin, warfarin, and other drugs given to prevent clotting. Dietary fiber also affects drug absorption. Pectin and other soluble fibers slow down the absorption of acetaminophen, a favourite painkiller. Bran and other insoluble fibers have a similar effect on digoxin, a major heart medication. As more and more people discover new herbs, there is more and more potential for the abuse of these herbs and the patients might end up in serious problems.

Ginseng, according to research, can increase blood pressure, making it hazardous for those trying to keep their blood pressure under control. Ginseng, garlic or supplements containing ginger, when taken with the blood-thinning drug, Coumadin, can cause bleeding episodes. Coumadin is a very powerful drug that leaves tiny room for error, and patients taking it should never take any medication or otherwise before consulting a eligible health professional. In rare cases, ginseng might overstimulate resulting in insomnia. Consuming alkaloid with ginseng increases the risk of overstimulation and gastrointestinal upset. Long tern use of ginseng might cause menstrual abnormalities and breast tenderness in some women. Ginseng is not suggested for pregnant or lactating women.

Garlic capsules combined with diabetes medication can cause a hazardous decrease in blood sugars. Some people who are sensitive to garlic might experience heartburn and flatulence. Garlic has anti-clotting properties. You should check with your physician if you are taking anticoagulant drugs. Goldenseal is used for coughs, stomach upsets, menstrual problems and even arthritis. However, the plant’s active ingredient will raise blood pressure, complicating treatment for those taking antihypertensive medications, especially beta-blockers. For patients taking medication to control diabetes or kidney disease, this herb can cause hazardous electrolyte imbalance. High amount of consumption can lead to gastrointestinal distress and doable nervous system effects. Not suggested for pregnant or lactating women.

Guarana, an substitute cure being used as a stimulant and diet aid, contains 3 percent to 5 percent more alkaloid than a cup of coffee. So, if you are taking any medication that advises you against taking any drink with caffeine, you should refrain taking this stimulant. It might cause insomnia, trembling, anxiety, palpitations, urinary frequency, and hyperactivity. Avoid during pregnancy and alimentation period. Long term use of Guarana might lead to decreased fertility, cardiovascular disease, and several forms of cancer. Kava, a herb that has antianxiety, pain relieving, muscle resting and anticonvulsant effects, should not be taken together with substances that also act on the central nervous system, such as alcohol, barbiturates, anti depressants, and antipsychotic drugs.

St. John’s Wort is a favourite herb used for the treatment of mild depression.

The active ingredient of St. John’s Wort is hypericin. Hypericin is believed to exert a similar influence on the brain as the monoamine oxidase (MAO) inhibitors such as the one in major antidepressants. Mixing MAO inhibitors with foods high in tyramine, an amino acid, produces one of the most dramatic and hazardous food-drug interactions. Symptoms, which can occur within minutes of ingesting such foods while taking an MAO inhibitor, include rapid rise in blood pressure, a severe headache, and perhaps collapse and even death. Foods high in tyramine include aged cheese, chicken liver, Chianti (and certain other red wines), yeast extracts, bologna (and other processed meats), dried or pickled fish, legumes, soy sauce, ale, and beer.

Some patients report that Saint John’s Wort caused excessive stimulation and sometimes dizziness, agitation and confusion when taken with other antidepressants or over-the-counter medications like Maximum Strength Dexatrim and Acutrim. It also caused their blood pressure to shoot up. White Willow, an herb traditionally used for fever, headache, pain, and rheumatic complaints might lead to gastrointestinal irritation, if used for a long time. It exhibits similar reactions as aspirin (aspirin is derived from white willow). Long term use might lead to stomach ulcers.

Drug Interaction and Food

Drug interaction risk isn’t limited to herbal supplements. Certain foods can interact with medications.  People taking digoxin should refrain Black licorice (which contains the ingredient glycyrhizin). Together, they can produce irregular heart rhythms and cardiac arrest; licorice and diuretics will produce dangerously low potassium levels, putting a patient at risk for numbing weakness, muscle pain and even paralysis. Licorice can also interact with blood pressure medication or any calcium channel blockers. Aged cheese (brie, parmesan, cheddar and Roquefort), fava beans, sauerkraut, Italian green beans, some beers, red wine, pepperoni and overly ripe avocados should be avoided by people taking MAO antidepressants. The interaction can cause a potentially fatal rise in blood pressure. And because Saint John’s Wort contains the same properties as these MAO antidepressants, it stands to reason that people ingesting the herb should refrain these same foods.

Grapefruit juice interacts with calcium channel blockers (including Calan, Procardia, Nifedipine, and Verapamil), cholesterol control medications, some psychiatric medications, estrogen, oral contraceptives and many allergy medications (Seldane, Hismanal). The juice modifies the body’s way of metabolizing the medication, affecting the liver’s capability to work the drug through a person’s system. Orange juice shouldn’t be consumed with antacids containing aluminum. ‘The juice increases the absorption of the aluminum. Orange Juice and milk should be avoided when taking antibiotics. The juice’s acidity decreases the effectiveness of antibiotics, as does milk.

Milk also doesn’t mix with laxatives containing bisacodyl (Correctol and Dulcolax). You might find the laxative works a tiny “too well” in the morning. Massive amounts of meal and other high-fiber cereals should not be ingested when taking digoxin. The fiber can interfere with the absorption of the drug, making the act of swallowing the pill a waste of time. However, don’t stop intake your cereal right away, because that could cause digoxin levels in your system to soar to toxic levels. A professional should make the dietary changes after carefully analyzing the digoxin levels.

Leafy green vegetables, high in vitamin K, should not be taken in great quantities while taking Coumadin. These vegetables could completely negate the affects of the drug and cause blood clotting. Caffeinated beverages and asthma drugs taken together can cause excessive excitability. Those taking Tagament (Simetidine), quinolone antibiotics (Cipro, Penetrex, Noroxin) and even oral contraceptives should be aware these drugs might cause their cup of coffee to give them more of a Java jolt than they expected. Grilled meat can lead to problems for those on asthma medications containing theophyllines. The chemical compounds formed when meat is grilled somehow prevent this type of medication from working effectively, increasing the possibility of an unmanageable asthma attack.

Regularly consuming a diet high in fat while taking anti-inflammatory and arthritis medications can cause kidney alteration and can leave the patient feeling, drowsy and sedated. Alcoholic beverages tend to increase the depressive effects of medications such as benzodiazepines, antihistamines, antidepressants, antipsychotics, muscle relaxants, narcotics, or any drug with sedative actions. It’s a good intent to not consume any alcoholic beverages, or at least scale way back, when taking prescription medications. Antioxidant and beta-carotene intensify alcohol’s effect on the liver. Other commonly used over-the-counter medications can cause interaction problems also.

Aspirin can alter the effectiveness of arthritis medications, strong prescription steroids and diuretics. Combining aspirin with diabetic medications can drop blood sugars to hazardous levels. Aspirin can also cause toxicity when taken with glaucoma and anticonvulsant (anti-seizure) drugs and cause bleeding episodes when combined with a blood thinner, like Coumadin. Acetaminophen can also cause interaction complications when overused. Heavy drinkers who take acetaminophen for hangover relief risk liver damage. Taking high doses of acetaminophen with Coumadin can cause bleeding episodes.

Antacids taken with antibiotics, heart and blood pressure or thyroid medications can decrease drug absorption by up to 90 percent. Over-the-counter antihistamines – sold under the obloquy Actifed, Theraflu, Dimetapp, Benadryl and Comtrex should be avoided if you are taking antianxiety or antidepressant medications. Oral contraceptives are less effective when taken with barbiturates, antibiotics, anti-fungal or tuberculosis drugs.

Turnips contain two goitrogenic substances, progoitrin and gluconasturtin, which can interfere with the thyroid glands capability to make its hormones. Even though moderate consumption of goitrogens is not a hazard for healthy people, they can promote development of a goiter (an enlarged thyroid) in persons with thyroid disease. Tomato contains small quantities of a toxic substance known as solanine that might trigger headaches in susceptible people. They are also a relatively common cause of allergies. An unidentified substance in tomatoes and tomato-based products can cause acid reflux, leading to

indigestion and heartburn. Individuals who often have digestive upse

Allergies are basically a mistake on the part of the immune system and are typically developed during life transition times. Using NLP you can often eliminate an allergic response to something. If you have an allergy, find a competent NLP Practitioner who has been through a legitimate and thorough NLP Practitioner Training. This process is not intended to replace appropriate medical care. As always, check with your physician to be responsible about your health.

An allergy takes place when the immune system suddenly has an abnormal response to a certain material that is usually not detrimental to most individuals except those who have allergies. When an allergy is triggered by a substance or allergen, a person’s body recognizes this as a trespasser and subsequently releases chemicals to fight off the “trespasser” causing symptoms that can range from a easy irritation to a fatal reaction that might even lead to death.

Food allergy is a reaction prefabricated by the immune system in which antibodies are produced by the body as a result of a negative effect to some foods. Though there are many individuals who claim that they have food allergies, there are only a few who really have certain allergic reactions to food. Most people confuse food allergy with food intolerance. Food intolerance and food allergy are both sensitivity reactions to food, but intolerance to certain types of food does not affect the immune system and isn’t really a life threatening incident.

As of the present time, the medical world still has not found any cure for food allergies. Allergy management only involves the prevention of intake of food allergens and some diet modifications.

Looking closely, during an allergic reaction, the body’s immune system releases antibodies, specifically immunoglobulin E. It subsequently causes the production of chemicals like histamine in the process of “protecting” the body. Now, these chemicals are the root cause of symptoms which might include an irritation in the eyes, skin, throat, lungs, and the gastrointestinal organs. These takes place whenever the individual is exposed to the allergen.

Although any type of food can cause allergic reactions to different types of individuals, there are eight major foods out there that are often the main culprits of an allergic reaction. These eight major allergy-causing foods are: fish, soy, milk, wheat, eggs, peanuts, tree nuts, and shellfish.

By and large, individuals afflicted with allergies react only to some allergy-causing foods. Sometimes, allergy to a certain type of food might also cause allergic reaction to foods that might be related with the allergen food. This incidence is known as cross-reaction. For instance, an allergic reaction to wheat might also cause a reaction to rye. Allergy to pollens subsequently causes an allergy to green apples, hazelnuts, almonds, and peaches. A reaction to goat’s milk might also be associated with an allergy to cow’s milk. And the list goes on and on.

Moreover, individuals who have been afflicted with asthma and/or eczema might also be at risk of developing a food allergy. With bad luck, they would probably have a reaction that is more severe than those people who only have food allergy to worry about. This is due to the fact that when an allergy takes place the mortal will be under stress which then might lead to triggering their asthma and/or eczema which will aggravate the situation.

But the intensity of the reaction will depend on some circumstances like the individual’s sensitivity threshold to the food allergen, amount of ingested food, and the exposure scale the mortal has to the food.

Although, there is no cure to allergies, self-discipline and vigilance will help you, the allergy-sufferer, overcome these food problems. There might be some medications out there that alleviate the symptoms but a consultation to the doctor will give you a superior understanding to your allergy problems as well as treatment recommendations.

Allergy season is now in full swing, and people everywhere are looking for tips to get rid of allergies. One of the first things you should do if you suspect allergies, is to go have an allergy test done. This test is usually done at either your primary care physician’s office, or at the office of an Allergy and Immunology doctor.

Allergies come in all shapes and sizes. Some are seasonal, such as hay fever. Some are constant, such as food allergies. Some are only on exposure to certain substances, such as chemicals or colourants.

The classic allergic reaction, which is classified as the type-1 hypersensitivity reaction, can be elicited by food, but this is evenhandedly uncommon. When we discuss food sensitivities in ADHD we are discussing a different, not well-defined, mechanism.

Allergy means the reaction of the body due to an immune response and reaction. Allergens will cause allergic reactions. Sneezing, runny nose, itchy eyes and ears, severe wheezing, coughing, shortness of breath, sinus problems and a nettle-like rash are the common symptoms of an allergy.

There are certain common factors causing an allergy. Touching grass, smelling dust, chemicals, and medicines, insect bites and intake certain types of food might cause an allergic reaction. Asthma, Bronchitis, Eczema, Dermatitis, and Urticaria are also some forms of allergy.

Allergy prevention has to start with allergy recognition. Once you have determined exactly what you are allergic to, you can practice prevention based on the problem. For environmental allergies such as pollen, simply avoiding exposure is one of the ideal preventative methods. This will require tracking of the pollen counts, and staying inside if they are unusually high. Keeping all windows shut and running the air conditioner is also a helpful pollen allergy prevention.

And they are expressed by your body in different ways. Some people get skin complaints such as hives or skin eruptions. Some get it in their upper respiratory tract with typical hay fever symptoms. Some get it in their digestive tract with diarrhoea a common symptom.

There are several vitamins, minerals, and herbal remedies that are good at relieving allergy symptoms and strengthening the immune system. Vitamin B5, vitamin A, and Omega-3 Fatty Acids can help to relieve allergy symptoms, such as congestion, coughs, and runny nose. Quercetin is a plant compound that can be found in foods, such as onions, apples, and citrus fruits, that can prevent the secretion of histamine. Histamine is a chemical that the body produces during an allergic reaction that causes sneezing and other symptoms. Butterbur is a herb that is good at relieving hay fever symptoms. Licorice root, astragalus, and capsicum are also good at curing allergy symptoms.

Symptoms Of Food Allergy

Food allergy is an allergic reaction to certain types of food. Aside for the similarities in symptoms, a food allergy is more severe than food intolerance. Someone with food intolerance can take small portions of the food he is allergic to.

There are many different things that people are allergic to. Something that commonly causes food allergies is wheat. People who are allergic to wheat often experience weight acquire as a result of their reaction. It is probably difficult to envision something common as wheat to cause problems. Most of the products that you take contain some traces of wheat in them.

Two common types of eye allergies:

* Seasonal Allergic Conjunctivitis (SAC)
* Perennial Allergic Conjunctivitis (PAC)

When it comes to treating allergies, the homeopathic medicines can also establish to be very effective. The homeopathic treatments have been used for centuries in India and it also became very favourite in Europe later. More recently, homeopathy has started gaining popularity in the United Says of USA also. This field of medicine takes a different approach to health and wellness, as it uses minerals and herbs and other practical applications to assist the symptoms of allergies. It basically works by stimulating the natural defensive power of the body.

An allergenic or reactive food is one that causes an allergic reaction, such as hives, wheezing, stomach cramps or stuffy nose. The foods that tend to be most highly allergenic (especially to children) are: milk wheat corn sugar soy nuts eggs.

While the condition known as allergies can vary from mortal to mortal in terms of what they are allergic to and how bad their allergies are, there are a lot of different ways that you can reduce the intensity and and occurrence of your symptoms on a day to day basis, so you can feel superior and be more productive.

Food allergies might be merely annoying, or they might be life-threatening. About 30,000 Americans rush to emergency rooms each year to receive treatment for serious allergic reactions to foods.   For about 150-200 people, these reactions are fatal. People with food allergies must be careful about what they eat. They also worry about “hidden” allergens that might sneak into their food.

What exactly is a food allergy? It’s a specific type of adverse food reaction that involves the immune system.   The body produces an allergic antibody to a food. Then, the next time that food is eaten, the antibody binds with the food and causes an allergic response.

Signs and symptoms might develop within minutes or within an hour after intake the offending food.   Here are some of the most common:

• itching, skin rash, hives

• swelling of the lips, face, tongue, throat or other body part

• nasal congestion, wheezing, or difficulty breathing

• abdominal pain  with diarrhea, nausea, and/or vomiting

• lightheadedness or dizziness

These symptoms can become hazardous if any of these responses occur:

• swelling of the throat or air passages that makes it difficult to breathe

• anaphylactic shock (involving a severe drop in blood pressure)

• rapid, irregular pulse

• loss of consciousness

How can people with common allergies protect themselves? It helps a lot to read packaging labels carefully.   The FDA requires food manufacturers to list the presence of the most common food allergens on their labels.   These are the 8 foods included in the labeling requirements: milk, eggs, peanuts, tree nuts (such as almonds, cashew, and walnuts), fish (such as bass, cod, and flounder), shellfish (such as crab, lobster, and shrimp), soy, and wheat.   If the product contains one of these foods or a accelerator from one, it must be listed.

Any domestic or imported food  regulated by the FDA must supply information such as “contains eggs” on the label. This stipulation also includes any of these allergens found in flavorings, colorings, or other additives in that product. If a food may  accidentally come in contact with one of these allergens during the growing, harvesting, or manufacturing process (for example, if peanuts are processed in the same plant), the manufacturer is not required to mention this on the label, but many do list the possibility of trace amounts of a common allergen.    Errors of omission do occur, but, when government inspectors notice that a product contains an unlisted allergen, there is a recall of the product.

The government’s labeling stipulations do not protect everyone with a food allergy.   The 8 most common offenders listed above statement for 90% of all food allergies.   However, more than 160 different foods are known to cause allergic reactions.

Here are some interesting and useful facts to know about food allergies:

• Food allergies reflect patterns of consumption.   In Japan, rice is a common allergen.   In Europe, mustard and celery are.

• Food allergy occurs in 6 – 8% of kids 4 years old or younger.   In adults, the figure is 3. 7%

• Allergies to peanuts and tree nuts are the leading causes of fatal and near-fatal reactions.

• Accidental exposure to allergens occur in about 50% of people with food allergies.

• The most common food allergies in adults are to seafood, peanuts, and tree nuts.

• The most common foods allergies in kids are to eggs, milk, and peanuts.

• Adults usually keep their food allergies for their entire lives, but kids sometimes outgrow theirs.

• The highly allergic mortal can become sick from intake even a very little amount of a food allergen, for  example, a small piece of a peanut kernel.

• Some allergic food reactions occur only after exercise.

• A positive test for IgE antibodies to a particular food does not necessarily mean that the mortal will  experience an allergic symptom after intake that food.   In fact, there’s less than a 50% chance that the mortal actually has that food allergy.

Food allergies are different from food intolerance.   Some food ingredients that can make a mortal sick because of intolerance are histamine, lactose, food additives (such as MSG and sulfites), and  gluten.

A health care bourgeois should be consulted for help in diagnosing and treating food allergies. The websites of the National Institute of Allergy and Infectious Diseases have a wealth of information on these topics on diagnosis and treatment of food allergies, but, ultimately, the allergic person’s ideal source of information is his/her own doctor, who can take a medical history, do an exam, do allergy tests, and think about the patient’s other medical problems before treating the allergy.

If you are a mortal with a history of hazardous allergic reactions, two possibly life-saving suggestions are the following:  1) wear a medical signal bracelet or necklace that says the food allergy you have and doable severe reaction(s) to it; and 2) consult your physician about the advisability of carrying an auto-injector device containing epinephrine (adrenaline) that you could administer to yourself if necessary.   (You will need a doctor’s prescription for this. )

FoodSafety. gov also advocates signing up for allergy alerts by email.   These can let you know about food recalls because of unlisted allergens on product labels.   You can also subscribe to an allergy signal newsfeed.

May 9 – 15 was designated Food Allergy Awareness Week.   But, for allergic people and those that cook for them and care for them, awareness must be ongoing each week and each day of the year.

Among the allergies rampant in American lives nowadays, food allergy is one of the prime three. But, some people misdiagnose food allergy as food intolerance.

An allergy to food is when you’ve got an adverse physical reaction to a food item when intake it. The foremost common food allergy is a Peanut Allergy, which affects from one% – 1.5% of the population. It’s conjointly doable to outgrow a food allergy over time, but with a peanut allergy, this can be rather unlikely.

Before we tend to go any additional let’s define specifically what a food allergy is. Food allergies will be de-escalated into a pair of categories. The second category is food intolerance. This can be really caused by the food itself and is not a operate of the immune system itself overreacting to the food or food additive. What actually happens with food allergies is that individuals with allergies produce IgE antibodies to specific epitopes in the food allergen. Hypersensitive reactions to food will be fatal almost immediately following the ingestion of food.

Probably one among the most prevalent and hazardous of those food allergies are individuals who are allergic to peanuts. Less severe reactions to food allergies are oropharyngeal pruritus, angioedema, stridor, cough, dyspnea, wheezing, and dysphonia.

Symptoms Of Food Allergy

Food allergy is an hypersensitivity to bound varieties of food. Aside for the similarities in symptoms, a food allergy is more severe than food intolerance.Someone with food intolerance can take tiny portions of the food he’s allergic to.

A food allergy will be treated as soon as the symptom occurs. Unfortunately the simplest means to refrain food allergies is to possess a food allergy check done and then to refrain the foods that show positive on the test. As of currently, an attempt of epinephrine is the most effective treatment for food allergy and substitute types of allergies.

Though food allergies can't be prevented, the simplest method to defeat it’s by staying removed from the food a mortal is allergic to. Creating the correct diagnosis on food allergy versus food intolerance will be tricky.Welcome to the world of food allergies and intolerances.

A Kid Can Outgrow Food Allergy

Food allergies affect an increasing range of kids, with peanut allergies being the foremost prevalent, (up to now an estimated one-a pair of% of kids affected by the probably life threatening hypersensitivity).

Therefore it offers some live of hope, to oldsters of food allergic children, to comprehend that around 1 in five kids eventually go on to outgrow their food allergy. Youngsters and adult allergies follow absolutely different patterns. A food allergy in your kid is most likely to come back from milk, eggs and peanuts. A food allergy in your kid might be prevented by avoiding high-risk foods.

In order to get rid of cystic acne, it’s an excellent intent to refrain junk food. Some people, no matter what they do in terms of diet, exercise, and general lifestyle changes, continue to have cystic acne that requires medical treatment. You might be an example of the extremely fortunate individual whose skin responds just to changes in diet. It’s unfair, however, to recommend that an improved diet will be a panacea for all people with acne.

Obviously, if an individual notices a connection between intake a certain food, for example, chocolate, shell fish, spinach, fried foods, and breakouts, he or she should refrain those foods. But not everyone has such clear flags.

But food is not the only cause for cystic acne. Frankly I sometimes wonder if more people don’t have adult cystic acne because of our toxic environment, including our food.  Or maybe part of it is that everybody didn’t feel as great a need to be perfect in the past. Maybe more people are seeking acne treatment now than in the past, I’m not saying that seeking treatment is necessarily a bad thing; if help is available, why not take advantage of it?

My advice is to press the physician for something else and if it doesn’t work seek a new physician who will prescribe Accutane or something similar for a five-month course. Cystic acne is just too unpleasant a condition to be lived with if there is a medication that can control it and the risks are reasonable.

Either food allergy or food intolerance affects almost everyone at some point. When people have an unpleasant reaction to something they ate, they often think that they have an allergy to the food. Actually, however, only up to 3% of adults and 6%-8% of kids have clinically proven true allergic reactions to food.

 

This difference between the prevalence of clinically proven food allergy and the public’s perception of the problem is due primarily to misinterpreting food intolerance or other adverse food reactions to food as food allergy. A true food allergy is an abnormal response to food that is triggered by a specific reaction in the immune system and expressed by certain, often characteristic, symptoms.

 

Other kinds of reactions to foods that are not food allergies include food intolerances (such as disaccharide or milk intolerance), food poisoning, and toxic reactions. Food intolerance also is an abnormal response to food, and its symptoms can resemble those of food allergy. Food intolerance, however, is far more prevalent, occurs in a variety of diseases, and is triggered by several different mechanisms that are distinct from the immunological reaction responsible for food allergy. People who have food allergies must refer and prevent them because, even though usually mild and not severe, these reactions can cause devastating illness and, in rare instances, can be fatal.

 

Symptoms and Signs of Food Allergy:

 

The complex process of digestion affects the timing, location, and particular symptoms of an allergic reaction to food. All of the symptoms of food allergy occur within a few minutes to an hour of eating. A food allergy can initially be experienced as an itching in the mouth and difficulty swallowing and breathing. Then, during digestion of the food in the stomach and intestines, symptoms such as nausea, vomiting, diarrhea, and abdominal pain can start. Incidentally, the gastrointestinal symptoms of food allergy are those that are most often confused with the symptoms of different types of food intolerance.

 

As mentioned previously, the allergens are absorbed and enter the bloodstream. When they reach the skin, allergens can induce hives or eczema, and when they reach the airways, they can cause asthma. As the allergens travel through the blood vessels, they can cause lightheadedness, weakness, and anaphylaxis, which is a sudden drop in blood pressure. Anaphylactic reactions are severe even when they start off with mild symptoms, such as a tingling in the mouth and throat or anguish in the abdomen. They can be fatal if not treated quickly.

 

Do infants and kids have problems with food allergy?

 

Most allergies to foods start in the first or second year of life. While some of these reactions might resolve over time (such as allergies to cow’s milk or eggs), other food allergies acquired in infancy (such as allergies to nuts or shellfish) typically preserve throughout life. Allergies to milk or soy formula (a milk alternative prefabricated from soybeans) sometimes occur in infants and young children. These primeval allergies sometimes do not involve the usual hives or asthma but rather can cause symptoms resembling infantile colic, and perhaps blood in the stool, or poor growth.

 

Breastfeeding: Exclusive breastfeeding, that is, excluding all other foods, for at least the first four months of life appears to help protect high-risk kids against milk allergy and eczema in the first two years of life. Breast milk contains less accelerator that is foreign to the infant and, therefore, is less allergenic than cow’s milk or soy formula.

 

Exclusive breastfeeding should be a consideration, therefore, especially in infants who are predisposed to food allergy. Some kids are so sensitive to a certain food, however, that if the mom eats that food, adequate quantities enter the breast milk to cause a reaction to the food in the child. In this situation, the moms themselves must refrain intake those foods to which the baby is allergic. No conclusive evidence has been obtained that recommends that breastfeeding prevents the development of allergies later in life.

 

Special considerations in children: An allergic child who itches, sneezes, and wheezes a lot can feel miserable and, therefore, sometimes misbehave or appear hyperactive. At the other extreme, kids who are on antiallergy medicines that can cause drowsiness might become sleepy in school or at home. Parents and caregivers must comprehend these different behaviors, protect the kids from the foods that induce their allergies and know how to manage an allergic reaction, including how to administer epinephrine. Also, schools need to have plans in place to address emergencies, including anaphylactic shock.

 

Allergies Home Remedies:

Allergies treatment using Nutrients

Certain nutrients have been found beneficial in the prevention and treatment of allergies. Often the intake of vitamin B5 or pantothenic acid brings great relief to the sufferer. This vitamin might be taken in a dose of 100 mg regular for a month. In such cases, liberal amounts of pantothenic acid helps even though the recovery takes several weeks. A dose of 400 mg of vitamin E taken regular for four to six weeks is also beneficial as this vitamin possesses effective anti-allergic properties.

 

Allergies treatment using Castor Oil

It is found that five drops of castor oil in half a cup of any fruit or vegetable juice, or plain water, and taken on an empty stomach in the morning, is beneficial for allergies of the intestinal tract, skin, and nasal passages.

 

Find powerful herbal remedies Calcium Supplements

Allergies treatment using Lime

Lime is considered an effective cure for any kind of allergy. Half a lime might be squeezed in a glass of lukewarm water and sweetened with a teaspoon of honey. It can be taken once regular first thing in the morning for several months. This cure not only flushes the system of toxins but also acts as an antitoxic and antiallergic agent. However, those who are allergic to citrus fruits should not take recourse to this remedy.

 

Allergies treatment using Bananas

One or two bananas a day are useful for those who are allergic to certain foods and who consequently suffer from skin rashes, digestive disorders, or asthma, The fruit does, however, cause allergic reactions in certain sensitive persons and they should refrain it.

 

Allergies treatment using Vegetable Juices

A quantity of 500 ml carrot juice or a combination of carrot juice with beet and cucumber juices, has been found beneficial in the treatment of allergies. In the case of blended juices, 100 ml apiece of beet and cucumber juices should be blended with 300 ml of carrot juice to prepare 500 ml or half a litre of blended juice. This should be taken once daily.
