The O blood type diet refers to an eating plan specifically for those with type O positive or negative blood. Peter D’Adamo, a naturopath, popularised the idea that a diet based on blood type could help a person achieve good overall health and reduce the risk of developing certain diseases. However, research on the effects of a blood type diet is scarce, and the studies available have not proven its effectiveness. For example, the authors of a 2014 study concluded that their findings did not support the claims that a blood type diet provides specific benefits.

What You'll Learn
Type O blood thrives on animal protein
Peter D'Adamo, a naturopath, popularised the idea that a diet based on blood type could help a person achieve good overall health and reduce the risk of developing certain diseases. According to D'Adamo, type O blood is an inherent meat eater and thrives best on animal protein from meat, poultry and fish.
Type O blood types are recommended to avoid dairy, cereal grains and legumes. This is because type O is the oldest blood type and mimics the purported eating patterns of the earliest humans, who lived during the paleolithic era or the "stone age". Hunters and gatherers lived a nomadic life, traveling from place to place, hunting wild animals and gathering edible plants.
The NYU Langone Medical Center points out the restrictive nature of the type O recommendations. In particular, the type O diet eliminates entire food groups that are otherwise healthy, such as dairy, legumes and grains. If you eliminate entire food groups, you might miss out on certain vitamins, minerals and other vital nutrients, warns the Langone Medical Center.
Type O blood types are recommended to eat lean red meat and game meat over fattier meats. Healthy oils such as olive oil are also recommended for all individuals with type O blood. Other beneficial foods for type O include nuts and seeds and fresh fruits and vegetables.
