Soy Allergy

Soy AllergySoy can be ingested in a variety of forms: as whole soybeans, oil, or flour. It is also used in food products in a variety of ways: as an emulsifier, a texturizer, or a protein filler. It is used in nutritional products (protein powders, for example) and vegetarian products (meat substitutes, for example) for its protein content. Because it can be used in so many ways, soy is often a hidden allergen, and it is very difficult to avoid in your diet. See one of the allergy specialists at NY Allergy & Sinus Centers for help.

*Since food allergies are reactions to the proteins in a given food, it was originally believed that soybean oil and soy lecithin are safe for soy-allergic individuals to consume. Now, it is evident that soy protein may occur in these products if they are not very pure. Approach these with caution.

Soy Allergy - cross-reactions between soy and other legumes are possible


There is evidence that cross-reactions between soy and other legumes are possible, though rarely symptomatic. Therefore, if your allergy tests have shown sensitivity to one legume, you may not have to eliminate all legumes from your diet. You should work with your NY allergist to develop dietary restrictions that are healthy and safe for you.
