Your blood plays a key role in your digestion system, the efficiency of your metabolism, and your mental and physical health. Besides, blood promotes the strength of your immune system and enables you to handle stress.

The idea of blood diet was first presented by a naturopathic physician Dr. Peter D'Adamo, who believes blood type is not only important for transfusion but also acts as the critical predictive marker for disease. His research showed a healthy diet should be determined according to the blood type because a distinct diet for each blood type is essential to maintain wellbeing.

The blood type diets are based on different types of blood determined by the ABO blood group system. According to Dr. D'Adamo, the food inside our stomach reacts with our blood type that contributes to both mental and physical health. Eating blood type diets enables your body to digest food more efficiently that in turn helps you lose weight, get healthier, prevent potential diseases, and have more energy.

While on the blood type diet, your food preferences, and choices when eating out will be determined by your blood type. You will have to severely restrict some foods you commonly eat depending on your blood group. But before eating the blood type diet, you will need to find out your blood type with the ABO blood group system.
