Before delving into the details of different foods that contain lectins, it’s important to understand what lectins are and their role in nature. Lectins are proteins that can bind to specific carbohydrates in a process called agglutination. This is a crucial function in many organisms, as it helps them to defend against harmful bacteria and other threats.

In terms of food, many common sources of lectins come from plant-based foods. This includes beans, nuts, seeds, fruits, vegetables, and grains. However, not all foods within these categories contain lectins, and some contain much higher levels than others.

  • Chili peppers
  • Soybeans
  • Lentils
  • Peas
  • Peanuts
  • Wheat

While many of these foods are considered healthy due to their nutrient content, it’s important to note that they may also contain other compounds that can be harmful in large amounts.

Other individuals may choose to limit their lectin intake due to autoimmune conditions or other health concerns, although the evidence for the effectiveness of this strategy is not clear.
