Ingredient notes

What to know about wheat flour

Wheat flour is the version of wheat that hides everywhere: it thickens sauces and gravies, coats fried food, and binds baked goods, so it catches people long after they think they have cut wheat. It contains gluten, is rated high in fructans and the FODMAPs, and rates poorly for SIBO. Because it is a hidden ingredient in processed foods, checking labels matters as much as skipping the obvious bread.

Watch for

  • Contains gluten, so it is not safe for celiac disease or gluten sensitivity even in tiny binding or thickening amounts
  • Rated high in fructans and FODMAPs, which is why floury sauces, roux and breaded foods can bloat sensitive guts
  • Hidden in gravies, soups, batters, coatings and processed snacks, so cross-contact and label reading are the real challenge
  • Rated poorly for SIBO, since its fermentable carbs feed overgrowth
