Blood Type Foods Diet
The blood types food diet, more popularly known as the "Eat Right For Your Type" diet, was developed by Dr. Peter D'Adamo. As the name suggests, a follower of the diet eats certain foods but abstains from others based on his individual blood type. This diet is based on D'Adamo's theory that due to genetic heritage, a chemical reaction occurs between the blood and food.

Description
-
According to D'Adamo, a chemical reaction occurs in the blood after food is consumed due to lectins. Lectins are proteins found in food that affect the blood. Depending on the type of lectin, this chemical reaction can be beneficial or detrimental to the body. The "Eat Right for Your Type" diet purports to restore the body's natural genetic rhythm by ensuring the individual only eats foods that bring about positive chemical reactions.
Foods are classified into three groups: highly beneficial foods, allowed foods and prohibited foods. As their names suggest, foods in the highly beneficial category act like medicine while foods in the prohibited foods category act like a poison. Allowed foods are neutral.
Type O
-
Type O's thrive on animal proteins, alkaline fruits such as berries and plums and intense physical exercise. However, Type O's must severely restrict or altogether eliminate the use of dairy products and eggs, particularly if the individual is of African ancestry. Cabbage, mustard greens, cauliflower and brussels sprouts must also be avoided by Type O's due to Type O's tendency to have thyroid problems. Lastly, grains, breads and legumes must be restricted initially and during periods of weight loss, as these foods cause Type O's to gain weight. However, grains, breads and legumes can be eaten in a limited fashion by Type O's long-term.

Type A
-
Type A's flourish on an organic vegetarian diet with gentle exercise. Thus, Type A's should severely restrict or eliminate meats from their diet and severely limit consumption of dairy products. Vegetables should be the main source of food in the Type A diet but potatoes, sweet potatoes, yams, cabbage, tomatoes and peppers should be avoided as the lectins in those foods are not compatible with Type A blood. Acidic fruits such as mangoes, papayas and oranges should also be avoided. The perfect Type A diet consists of tofu, vegetables, legumes and alkaline fruits.
Type B
-
Type B's thrive on a diet that is balanced and wholesome with moderate exercise. Deep-water fish, fruits, vegetables and dairy products are the most beneficial for Type B's. However, chicken, shellfish, nuts, seeds and tomatoes must be strictly avoided as their lectins are not compatible with Type B blood. Type B's should also avoid corn, buckwheat, lentils, peanuts and sesame seeds during periods of weight loss as these foods cause Type B's to gain weight.
Type AB
-
Type AB's flourish on a mostly vegetarian diet with calming exercise. Like Type A's, tofu should be a diet staple for Type AB's. Grains, particularly rice, fruits and vegetables should make up the majority of Type AB's diet with legumes, nuts and seeds eaten sparingly and with caution. Additionally, Type AB's should drink warm water with the juice from one-half of a lemon each morning before eating.
Criticism
-
The Eat Right for Your Type diet has been criticized for its lack of scientific study and published evidence supporting it. Opponents generally claim no plausible rationale for the diet exists in the medical community.
