food allergy

A condition that is widely percieved to be a major health problem, the incidence of which (0.3–7.5%) has been obscured by controversial data and differing disease definitions; food-induced reactions of immediate-hypersensitivity type are well recognised and include anaphylaxis, angiooedema and urticaria; food-induced reactions of delayed hypersensitivity type (mediated by antigen-antibody complex formation) are rarely documented, and include specific reactions (e.g., gluten-sensitive enteropathy).
 
Clinical findings
Oedema and pruritus of oropharyngeal mucosae, followed by various responses in the gastrointestinal tract as the offending content works through the system, including vomiting, colic, abdominal distension, flatulence, diarrhoea, and less commonly, occult blood loss, malabsorption, protein-losing enteropathy, functional gastrointestinal obstruction and eosinophilic gastroenteritis.
 
Lab
Elimination (challenge) diet, rotation diet, in vivo (intradermal, multi-test, sublingual) testing and in vitro (IgE, IgG, IgG4, RAST, cytotoxic, histamine release) testing.

Allergy medicine A condition, the incidence of which–0.3-7.5%–is obscured by controversial data and differing disease definitions; food-induced reactions of immediate-hypersensitivity type are common and include anaphylaxis, angioedema, urticaria; food-induced reactions of delayed hypersensitivity type or those mediated by antigen-antibody complex formation are uncommon and include gluten-sensitive enteropathy Clinical Edema and pruritus of oropharyngeal mucosa, followed by various responses in the GI tract as the offending, and ultimately offensive, content traverses the system–eg, vomiting, colic, abdominal distension, flatulence, diarrhea, less commonly, occult blood loss, malabsorption, protein-losing enteropathy, functional GI obstruction, and eosinophilic gastroenteritis Diagnosis Elimination/challenge diet, rotation diet, in vivo–intradermal, multi-test, sublingual testing, and in vitro–IgE, IgG, IgG4, RAST, cytotoxic, histamine release testing. Cf Food intolerance.

food allergy

Sensitivity to one or more of the components of normal diets. Food allergy is much less common than unscientific claims might suggest and established methods of testing, including DOUBLE-BLIND TRIALS have shown that food allergy is not the basis of the many disorders commonly claimed to arise from it. PEANUT ALLERGY is becoming more common and may be dangerous. Monosodium glutamate can cause the ‘CHINESE RESTAURANT SYNDROME’. Tartrazine sensitivity is established. Other additives, such as sulphur dioxide, sulphites, azo dyes and benzoate preservatives also sometimes cause genuine allergic reactions, such as asthma. Allergy to basic foodstuffs seldom occurs.

Patient discussion about food allergy

Q. Can you define celiac as a food allergy? and if you can- how come you can't treat it with alternative medicine- like you do for other types of food allergies???

A. No, celiac is not defined as a food allergy, because the mechanism of injury to the bowel mucose after exposure to gluten containing products is much more severe than the regular allergic reaction. The damage caused to the bowel is by severe inflammation and destruction of the bowel "villi", and in a regular food allergy the only problem caused is either mal-digestion or other allergic manifestations such as a rash (aside from actual anaphylaxis).

Q. How long does it take for an allergy to occur after eating a food? Ok, I am allergic to peppers, each time I get an allergic reaction it takes longer and longer for the allergy to occur last time it was nearly 10 hours after eating the food this time it was 17 hours after eating the food. Is this even possible? I thought reactions occurred at max 4-6 hours after eating the food

A. i have a LOT of allergies. i am allergic to nuts very bad and i ate a chocolate with a nut in that a didn't notice, 10 seconds after digesting gave me a bad feeling in my throat and a few more seconds later i was violently sick and couldn't breathe very well and needed to call an ambulance 10 seconds later. i think its how bad the allergy, the quicker it starts to take effect.

Q. Is it possible to show external symptoms with a food allergy? The research I've done only mentions irritation of the throat and mouth, wheezing, etc. But is it possible to develop hives and itching on your back, arms, legs, but not have any irritation in your throat, mouth, etc, when you're affected by a food allergy, such as soy? Also, is it possibly a food allergy if the hives take a long time to go away, maybe a day or two?

A. Yes, it is possible. This exact same thing happens to me when I eat avocado products.
My skin whelps up, turn's red and itches like nothing else...
I hope that this helps and good luck with your allergies!
