What is blood type A? Blood type A forms when the O antigen, or fucose, and another sugar called N-acetyl-galactosamine, are combined together. Basically, fucose and N-acetyl-galactosamine equal blood type A. Antigens are found on the cells of the body, and every life-form has unique antigens that are part of their chemical fingerprint.

According to Dr. D’Adamo, there are certain factors that make it difficult for someone with type A blood to digest and metabolize animal protein and fat.

This includes someone with type A blood having low levels of intestinal alkaline phosphatase, high intestinal disaccharide digestive enzymes that permit efficient carb digestion, and low levels of hydrochloric acid in the stomach.

Although the blood type A diet is not a weight loss plan, losing weight is a beneficial side effect of the diet. As mentioned, people on the blood type A diet will thrive on a vegetarian diet.
