I'm not sure if for me it's fructans or not, since I do fine with garlic and onion. I hardly eat any commercially prepared food which has also helped.
BTW (completely off topic) After thanksgiving in Oct I made a broth with the turkey carcass and some meat. I know you make your own homemade broth with chicken. I just wanted to know how you do it exactly? Do you buy a whole chicken, or parts? One thing I noticed right away was the consistency was like jello when cooled, and when I had soup from this broth my stomach was so calm and soothed. I'm never buying commercially made broth again, it's just not the same.
