Based on Dr. Peter DÁdamo, the author of Eat Right For Your Type, a chemical reaction occurs between your blood and the foods you eat. This reaction is part of your genetic inheritance. This reaction is caused by a factor called Lectins. Lectins, abundant and diverse proteins found in foods, have agglutinating properties that affect your blood. So when you eat a food containing protein lectins that are incompatible with your blood type antigen, the lectins target an organ or bodily system and begin to agglutinate blood cells in that area. Different lectins target different organs and body system.
Fortunately, most lectins found in the diet are not quite so life threatening, although they can cause a variety of other problems, especially if they are specific to a particular blood type. For the most part your immune systems protect you from lectins. Ninety-five percent of the lectins you absorb from your typical diets are sloughed off by the body. But at least five percent of the lectins you eat are filtered into the bloodstream and different reactions in different organs.
Your blood type diet is the restoration of your natural genetic rhythm. Your blood type diet works because you are able to follow a clear, logical, scientifically researched plan based on your cellular profile. Each food groups are divided into three categories: Highly beneficial ( food that acts like Medicine), Foods allowed (food that are no harm to the blood type) and Foods not allowed (food that acts like a Poison)
