Fructans
Fructans are fermentable carbs in wheat and alliums—IBS triggers for some, prebiotics for others; personal reintroduction sets your portion limits.
Fructans are FODMAP carbohydrates in wheat, onions, garlic, and some vegetables—they ferment quickly in the small intestine and cause bloating in sensitive people. They also act as prebiotics for others, so elimination is temporary during IBS protocols, not a universal evil.
Spreading intake and cooking strategies change tolerance individually.
Common questions
-
Do fructans have any health benefits?
Yes—they feed beneficial bacteria when tolerated. IBS protocols remove them short term, then reintroduce to find the largest comfortable dose.
