Blood Type Diet

The blood type diet is a strategic meal and lifestyle plan that was invented by Dr. Peter J. D’Adamo as a more individualized approach to losing weight. In addition to helping people successfully drop pounds, this diet is promised to improve overall health and well-being by fueling your body with foods that are easily digestible and appropriate for your specific blood type.

In order to understand why the blood type diet has developed, one must first understand what differentiates these specific categories of blood classification.

Someone with type A blood will have what is known as an antigen that is A specific. An antigen is a specific particle that could induce an immune response if the respective antibody for A antigens is present. Likewise, type B blood contains B antigens only. A combination of type A and B suggests that both antigen types are present within that individual’s red blood cells. Lastly, type O blood does not contain any antigens, however this type does contain antibodies that are reactive to A and B antigens. Our genetic DNA determines which antigens and/or antibodies are present within the blood, and this genetic makeup is where Dr. D’Adamo derives his diet inspiration. Based on historical evidence, he concluded that each blood type has a reputation for various disease susceptibilities, reactions, and general performance.

Individuals with type A blood are encouraged to eat a vegetarian diet with a focused attention to organic, unprocessed options. Type B individuals should try and avoid chicken, but are encouraged to eat other types of lean meat. Some other items on the ‘no’ list for type B blood types are corn, wheat, tomatoes, and lentils. The combination of AB antigens would lead D’Adamo to suggest food items like green vegetables, seafood, tofu, and dairy, but to avoid caffeine, alcohol and items with high amounts of sodium. Lastly, individuals with type O blood should focus on food options that are high in protein.

Aside from food choices, D’Adamo’s blood type diet also specifies certain types of exercise and behavioral habits that are most conducive and beneficial to each blood type. There are also a variety of distinct supplements that he believes to be more valuable and constructive than others, solely based on the DNA structure, history, and traditional characteristics of each blood type.
