I am reasonably complete in updating the database. If you know of any substances not shown below that have published peer review studies (a.k.a. PubMed) please email me with links so I may update it.
IBS is often concurrent with ME/CFS and FM.

For citizen science looking at probiotics, we actually have a short list and a longer one from PubMed. Lactobacillus GG showed up on both, and on the actual studies list. Clostridium butyricum (probiotics) also has a match from PubMed bacteria to Actual Studies. Different oligosaccharides were on the take and avoid list. Unfortunately, most studies on IBS did not test differences (i.e. tested the forest and not the tree species).
On the avoid list was inulin and it’s associated jerusalem artichoke. Recommending that is a “pro-forma” suggestions from many physicians. So what gives? For that one I did find a study. The study results suggested that you should avoid it — a nice agreement.
However, flatulence severity was improved by prebiotics at doses ≤6 g/d (SMD: -0.35; 95% CI: -0.71, 0.00; P = 0.05) and by non-inulin-type fructan prebiotics (SMD: -0.34; 95% CI: -0.66, -0.01; P = 0.04), while inulin-type fructans worsened flatulence (SMD: 0.85; 95% CI: 0.23, 1.47; P = 0.007).Prebiotics in irritable bowel syndrome and other functional bowel disorders in adults: a systematic review and meta-analysis of randomized controlled trials 2019
