Wheat flour on a low FODMAP diet

  • Leave wheat flour out during the elimination phase, which usually lasts two to six weeks.
  • Look for a low FODMAP alternative in the same food group, or check one in our FODMAP checker.
  • High FODMAP doesn't mean forever: during reintroduction, many people find they tolerate some high FODMAP foods in smaller amounts.

Which FODMAPs are in wheat flour

GOS: GOS (galacto-oligosaccharides) are found mainly in legumes. Like fructans, they aren't digested in the small intestine and are fermented by gut bacteria, which can cause gas and bloating. Read more about foods that cause bloating.

Fructan: Fructans are chains of fructose found in wheat, garlic, onion and some vegetables. People can't fully digest them, so they reach the large intestine, where gut bacteria ferment them. Read more about high FODMAP foods to avoid with IBS.
