Why lectin food checker matters

Lectins are proteins found in many plant foods, especially legumes and grains. Some people follow low-lectin diets believing they reduce inflammation and digestive issues, though properly cooked foods have reduced lectin content.

  • Proper cooking destroys most lectins - never eat raw beans
  • Pressure cooking is highly effective at reducing lectins
  • Peeling and deseeding reduces lectin content
  • Fermentation can reduce lectins in some foods
  • Sprouting may increase or decrease lectins depending on the food

What to know about whole wheat flour

Whole wheat flour is milled from the entire kernel, so it keeps the bran and germ that white flour discards. That extra layer is where much of the wheat fructan and fermentable fiber sits, so whole wheat flour is at least as high in fructans as refined flour, not lower, and it rates high FODMAP. It also contains gluten, exactly like white flour, so it is no help for celiac disease or gluten sensitivity. Anything you bake with it, from bread to muffins, carries that fructan and gluten load.

Watch for

  • Contains gluten, so choosing whole wheat over white flour makes no difference for celiac disease or gluten sensitivity
  • High in fructans, and the retained bran means it is not lower in FODMAPs than white flour despite the healthier label
  • Rates high FODMAP, so baked goods made with it commonly cause bloating and gas
  • The added bran raises the fermentable fiber, which can be harder on an IBS or SIBO-prone gut
