Cf Food intolerance.food allergySensitivity 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 allergyQ. 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??? 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 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? food allergy
