However,  a priori  is sometimes used to modify other nouns, such as truth. Philosophers also may use apriority and aprioricity as nouns to refer (approximately) to the quality of being  a priori .
Lectins are drawn right to that lining, and your immune system retaliates. Lectins are found in all foods, but in some more than others. All seeds of the grass family - wheat, rye, rice, spelt, etc. - are high in lectins. You also find lectins in beans, dairy and in the nightshades (tomatoes, potatoes, eggplant). According to a 1991 study, dairy may be potentially more harmful in pasteurized, processed milk because of the reduction of SIgA, an immunoglobulin that binds dangerous lectins.
Lectins are special proteins that exist in many types of foods. Only certain types of lectins are toxic â unfortunately, the lectins in grains and pseudograins fall into this group. Gluten is the best-known lectin, but far from the only one: non-gluten grains contain other lectins that many people react poorly to. Lectins disrupt your digestive process, and contribute to leaky gut syndrome, because your gut doesnât realize that they arenât simple sugars.
