5. Lectins. Lectins are found in high quantities in beans and wheat, which as mentioned earlier reduce nutrient absorption and can cause indigestion, bloating and gas for many people.
Although all foods contain some lectins, only about 30% of the foods we eat contain them in significant amounts (3). Legumes (including beans, soybeans and peanuts) and grains contain the most lectins, followed by dairy, seafood and plants in the nightshade family. Their function in plants is not clear, but they may have evolved as a survival mechanism.
