These supplements are supposed to target the health conditions associated with type O blood, like digestive issues. Many studies have debunked the diet while other studies have found some benefits of the diet unrelated to blood type. One study states that the diet may be popular because it emphasizes eating whole foods, avoiding processed foods, and exercising.
These principles are associated with many diets and are recommendations commonly given by doctors and nutritionists to improve or maintain health.
In , a systematic review in the American Journal of Clinical Nutrition looked at 16 previous studies on blood type diets. This will determine the effectiveness of the blood type diet.

Group B blood types were said to arise among nomadic tribes who consumed a lot of dairy products. And since Group AB blood was supposed to have evolved from the intermingling of people with types A and B blood, type AB recommendations were intermediate between those for people with types A and B blood.
Each of these theories has been challenged. For example, there is evidence that type A was actually the first blood group to evolve in humans, not type O. In addition, there is no proven connection between blood type and digestion. So, in addition to a lack of evidence that the diet works, serious questions remain about why it should work in the first place.
Eating based on your blood type requires you to know your blood type and then follow a restrictive diet.

If Harvard wants me to invest my money in their health publications, they should limit themselves to hard science and not use urban myths in the hope they might prove correct in a future study.
I totally support the Blood type diet.
