Sauerkraut
Portion-sensitiveWhy this food shows up for IBS
Fermentation doesn't add FODMAPs on its own, but raw cabbage's natural fructans and polyols remain in the finished product. Fermentation can also raise histamine and other biogenic amine content, which some IBS-adjacent guts react to independently of the FODMAP load.
