you've mentioned earlier that both bread and onions give you gas. Wheat and onions are high in fructans. Onions also contain fructose. Fructans are problematic for individuals with fructose malabsorption (FM). It depends on the severity of fructose malabsorption and the *amount* of wheat or onions eaten, how much gas will be produced. If you can eat two tablespoons of honey (high in fructose) without having obvious gas or diarrhea within 48 hours, you do not likely have fructose malabsorption.
