The most common food additives that people test they are allergic to over the years have been sulfites in all forms, tartaric acid, blue colorings (these cause ADD and ADHD), synthetic vitamin Es (especially alpha-tocopherol), chlorine, xanthan gum and nitrates in all forms. Oh, and Cochineal, Carminic acid which is made out of cockroaches so people especially allergic to bug bites wouldn’t do well with these.
