The deleterious effects of chronic dietary consumption of foods with high lectin contents is receiving a great deal of attention these days. Many common plant foods contain lectins which the plant employs as defense mechanisms. Gluten is a lectin. When humans consume such foods, the lectins in them deploy n the gut. The immediate mechanism of their action is to provoke an auto-immune reaction by way of molecular mimicry. Lectins (there are a great many) are functionally indistinguishable from proteins and bind to cell receptors causing havoc with hormone regulation.
