Because soy is a known allergen, some consumers may worry about including it in their diet. However, the list of the eight most common food allergens also includes proteins in milk, eggs, peanuts, tree nuts, fish, shellfish, and wheat. Like any of these allergens, soy is harmful to those who are allergic to it, but this has no bearing on its safety for the general population. Those with a known or suspected soy allergy should consult a health care professional for dietary guidelines and always read labels with care.
Myth: Soy upsets your stomach.
While any food can cause sensitivity in some people, there’s little scientific evidence that soy is more irritating to the stomach than other foods. Those with known or suspected soy allergies should consult with their healthcare provider before trying soy.
