Do you notice gas with other food? You might want to try a low FodMap diet. (Fermentable Oligosaccharides, Disaccharides, Monosaccharides, And Polyols). It avoids any food that ferments in your body. You first do an elimination diet of avoiding all high fodmap foods, then gradually add food back into your diet, one food at a time to see what causes you distress. If your gas is very smelly...avoid onions at all costs. I try to avoid all high fodmap foods but can't always. Even apples, pears, and stone fruit are high fodmap. We all know things like broccoli and cabbage cause gas, but seriously who doesn't love broccoli? I take a generic beano, a dairy aid (generic Lactaid), and a gluten aid, as well as maximum strength gas x (again, generic) Because I cheat and eat some high fodmap food including beans, I still get gas, but, by avoiding onions they aren't smelly for the most part. Yes, I could clear a room before this!
