Reading Labels and Possible Exceptions

Since most of my problem foods are among the 8 most common allergens, many times a quick scan for the major allergens is enough to reject a food product. For example, any mention of milk, tree nuts, or shrimp, and it’s out. But if it mentions wheat (gluten) or soy, I look further.

If the soy is in the form of soy lecithin or soybean oil, I can have it. Protein content in lecithin and commercial oils are so low that most people with allergies will tolerate these.

If the only source of wheat and soy is soy sauce, I can usually have it. Gluten content in commercial soy sauce is under 20 ppm for most brands and I can tolerate small amounts.

Of course this all depends on one’s sensitivity level, but knowing these exceptions can open up quite a few more options.

Exercise Induced Allergies

Exercise induced allergies are an example of symptoms being provoked only when two (or more) factors are present at the same time. This makes it much harder to tease out the cause(s).

Food dependent exercise induced anaphylaxis (FDEIA) was first described in a case study in 1979, which seems fairly recent by medical standards. In comparison, Aspergers (now high functioning Autism) was first described in 1944.

Wheat allergy and delayed migraine connection was first confirmed through DBPCFC (double blind placebo controlled food challenge: the “gold standard”) in 2006.

Other possibilities such as free glutamates (MSG), NSAIDs amplifying allergic reaction have been described.

A study of WDEIA (wheat dependent exercise induced anaphylaxis)* shows that both aspirin and exercise increase the presence of gliadin in the blood stream** and the chronic induced behavior may extend to NSAIDs, MSG, Benzoate and other synthetic chemical food additives.
