- QUESTION: I know my sister suffers from food allergy, though she won't admit
- to it and continues to eat everything that is put in front of her. Would you
- please help me by describing the symptoms of food allergy, and what foods most
- commonly cause the condition? Then maybe she will listen up and change her
- ways. Thanks for your help and your wonderful column.

- ANSWER: There are many symptoms and many signs of food allergy, but despite
- their number and the fact that some types of food allergy are relatively
- common, the diagnosis isn't always as easy as you may think.
- Let's start with some of the signs most people take for warning signals
- of food allergy and that relate to the gastrointestinal system. They include
- cramping and bloating, nausea and vomiting, gas and diarrhea. However, these
- are the same findings you may have in the case of food poisoning, or even a
- "stomach" virus. Respiratory signs of food allergy include: runny nose
- (rhinitis), shortness of breath and even asthma-like problems. Yet they are
- often mistaken for the common cold, allergy to pollen and flu. The skin can
- display signs of an allergy to food that include red blotches (erythema),
- hives and wheals (urticaria) or eczema. But these also occur when you have
- touched a plant, or come in contact with pesticides or other irritating
- chemicals.
- Systemic signs may be more severe and more life threatening. They may be
- seen as pallor, fatigue and irritability or even cause anaphylaxis, a life
- threatening situation in which the person goes into a state of shock. Other
- symptoms include low blood pressure, irregular heartbeats and severe
- headaches.
- The foods most commonly implicated in food allergy include cow's milk,
- eggs, nuts, shellfish, soy products, wheat, corn, bananas, chicken and melons.
- The trick in diagnosing the presence of a real food allergy is to match the
- symptoms with the food, and that takes a bit of doing. While laboratory tests
- and skin testing can aid in making the diagnosis, an oral food challenge, in
- which bits of dried food in gelatin capsules are used in an attempt to
- reproduce the symptoms, may be the only definitive test, though it is time
- consuming and difficult. Another technique is to use an elimination diet,
- removing one suspected food from the daily diet after another until the
- symptoms disappear.
