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

Ingredient notes

What to know about buckwheat

Buckwheat is naturally gluten-free, so it gets used as a wheat swap, but it carries its own triggers that have nothing to do with gluten. It is high in oxalates, high in nickel and high in lectins. That means it can still cause trouble for anyone managing kidney-stone risk, systemic nickel allergy or lectin sensitivity, so gluten-free does not make it a clean grain across the board.

Watch for

  • High in oxalates, worth limiting if you are prone to calcium-oxalate kidney stones
  • High in nickel, one of the higher-nickel pseudo-grains for anyone on a low-nickel diet
  • High in lectins, so it may not suit a strict low-lectin plan even though it contains no gluten
  • A recognised food allergen in its own right, separate from wheat: buckwheat allergy can be serious
