Blood Type Diet FAQ

Lectins


What is a Lectin?
A protein substance commonly found in foods that binds with glycoproteins and glycolipids on the surface of animal cells causing agglutination. Some lectins cause agglutination of erythrocytes in specific blood groups. (medical dictionary definition). Lectins also play a significant role in hormonal reactions.

In lay language, this translates to very tiny molecules found in foods that selectively cause blood and other body tissues to stick together. A lectin that causes the tissues of a person of one blood type to stick together will not necessarily have the same effect on a person of a different blood type.

Does sprouting destroy or neutralize lectins?
In some cases, yes. In other cases, such as alfalfa sprouts, the lectin activity is enhanced by sprouting. The recommendations for foods are inclusive of whether the food is eaten sprouted or cooked, unless explicitly stated otherwise.

Does cooking destroy or neutralize lectins?
In some cases, yes. In other cases, such as tomatoes, the lectin activity is enhanced by cooking. The recommendations for foods are inclusive of whether the food is eaten raw or cooked, unless explicitly stated otherwise.
