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
