Legumes, Beans, & Peanuts
Legumes are plants with a seed or pod that belong to a large family of plants. Because of their high lectin and phytic acid levels, legumes are not allowed on the paleo diet. Lectins and phytates can decrease the minerals in your meals, and some people who are sensitive to them may have other bad health impacts, therefore they're off the paleo diet's "no" list. This, like grains, is a source of debate in the scientific community.
All beans, peas, lentils, tofu and other soy foods come in the same group as legumes. Peanut butter and soy sauce are also should be avoided.
