3 Diets for 3 Blood Types

Three blood types exist in humans: A, B and O. O is the absence of the antigens that make up A or B blood (or AB blood that contains both types). A blood type diet is a nutrition plan based around one's blood type. Peter D'Adamo advocates this diet and asserts that it can assist with allergy and infection resistance in addition to weight loss and overall good health.

People with Type O blood should stay low-carbohydrate, high in protein and low in dairy products. Also, avocados, brazil nuts and oranges should be avoided. Type O people should engage in lots of exercise.

People with type A blood should avoid red meat and keep a low dairy intake while eating plenty of fish and vegetables. These people should only lightly exercise.

Blood type B people should avoid chicken and bacon while eating plenty of meat and dairy. Some fish and plenty of fruit and vegetables are also recommended.

People with blood type AB should follow guidelines for blood types A and B.

Aside from dietary suggestions, the blood type diet places people in other categories. Type O is the hunter, the earliest human blood group. Type A is called the cultivator which dates back to the beginning of an agricultural society. Type B is the nomad and is characterized by a strong immune system and a flexible digestive system. Type AB is the most recently evolved type and these people are called the enigma.
