Watch the Buscopan advert on the telly just now... If you have suspected IBS it might not be IBS. At the end of the advert the lady gets a french stick (no jokes please). My point is - right now in the UK they put raw soy flour(unfermented) into everything. Including 80 percent of the bread. The beans need a lot of treatment to be ready to eat. Soy should only be eaten a couple of times a week at most.
reactions to soy - abdominal pain diarrhea, nausea, or vomiting runny nose, wheezing, or trouble breathing fever blisters fever conjunctivitis (pink eye) skin reactions including hives and eczema itching and swelling anaphylactic shock (very rarely in the case of soy allergies)
