Blood Type Diet

The blood type diet, also known as the blood group diet, was popularized by a naturopathic physician called Dr. Peter D’Adamo in the year 1996.

The blood type diet is based on your blood type. If your blood type is A, you should eat vegetarian foods, if it is type O, you should eat mostly meat and not eat grains, and if it is type B, you can eat many types of food, such as dairy, which you cannot eat for type A and O.

This is how each blood type is supposed to eat:

BLOOD TYPE	DEFINITION	FOODS THAT CAN BE EATEN	FOODS THAT SHOULD NOT BE EATEN	EXERCISES
Type A	Called the agrarian, or cultivator. People who are type A should eat a diet rich in plants, and completely free of “toxic” red meat. This closely resembles a vegetarian diet.	Vegetables Fruit Grains Beans Legumes Nuts Seeds	Dairy Meat Fish Poultry Eggs Processed Foods	Calming exercise like golf or yoga
Type B	Called the nomad. These people can eat plants and most meats (except chicken and pork), and can also eat some dairy.	Vegetables Fruit Grains Beans Legumes Meat Poultry Fish Eggs Dairy	Nuts Seeds Processed Foods	Moderate-intensity exercise like walking, hiking, and tennis
Type AB	Called the enigma. Described as a mix between types A and B.	Seafood Tofu Dairy Beans Grains​	Kidney Beans Corn Beef Chicken Processed Foods	Both calming and moderate-intensity exercise
Type O	Called the hunter. This is a high-protein diet. It closely resembles the paleo diet	Meat Poultry Fish Olive oil Nuts Seeds Eggs	Dairy Grains like cereal; bread, pasta, and rice Beans Processed foods	Vigorous exercise like running

Any of these dietary patterns would be an improvement for most people, no matter what their blood type is.

All 4 diets (or “ways of eating”) are mostly based on real, healthy foods and a huge step up from the standard Western diet of processed junk food.

So, even if you go on one of these diets and your health improves, it doesn’t necessarily mean that it had anything to do with your blood type.

Maybe the reason for the health benefits is simply that you’re eating healthier food than before.
