Blood-type food lists can be found in the book "Eat Right 4 Your Type," written by Dr. Peter D'Adamo, who created the blood-type diet. Lists can also be found on websites such as Web MD and D'Adamo's website, which also offers recipes and online support.
Some examples of foods recommended for a person with type-O blood include vegetables and lean proteins such as poultry and fish, with limited grains and dairy. Someone with type-A blood is recommended to follow a vegetarian diet with emphasis on fruits, vegetables, legumes, beans and whole grains. According to the diet, someone with type-B blood should eat plentiful amounts of eggs, low-fat dairy, green vegetables and specific meats while the diet of an individual with type-AB blood should focus on seafood, dairy, green vegetables and tofu.
The blood-type diet proposes that each blood type reacts differently with various foods. The premise is that eating a diet that is designed for the individual's blood type enhances digestion, boosts energy, aids in weight loss and works to prevent disease. There have been very few clinical studies to support or refute these claims. The diet limits and restricts the foods that the individual can eat in addition to recommending exercises based on blood type.
