According to this theory D'Adamo has stated that there is a relationship between the blood and the foods one eats. According to him, there occurs a chemical reaction between food and blood which is caused by a factor called lectins. So when ones eat a food containing these lectins that are incompatible with ones blood type antigen, the lectins may begin to agglutinate blood cells in that area. DÁdamo has blamed lectins for the serious disruptions throughout the body, from agglutination of the blood cells to cirrhosis and kidney failure.
