A chemical reaction occurs between your blood and the foods you eat. This reaction is part of your genetic inheritance. It is amazing but true that today, in the twenty rst century, your immune and digestive systems still maintain favoritism for foods that your blood type ancestors ate.
We know this because of a factor called lectins. Lectins, abundant and diverse proteins found in foods, have agglutinating properties that affect your blood and the lining of your digestive tract. Lectins are a powerful way for organisms in nature to attach themselves to other organisms in nature. Lots of germs, and even our own immune systems, use this super glue to their benefit.
… when you eat a food containing protein lectins that are incompatible with your blood type antigen, the lectins target an organ or bodily system (kidneys, liver, gut, stomach, etc.) and can begin to interact with the tissues in that area.
