One type of diet for each blood group

We all notice that there are some foods that feel better and others worse. Now, a nutritionist theory tries to explain that the reason why we tolerate foods better than others can be in our ancestors and linked to our blood group. So not everyone should eat the same, since each organism is naturally predisposed to easily digest certain foods and does not have the same capacity for others.

The theory of diet linked to blood group

The first time it was mentioned that the diet was linked to the blood group and the origin of the nutritional activities of our ancestors was in the mid-nineties in the book Eat right for your type (Eat well, for your type) Dr. Peter D'Adamo.

His theory is based on the fact that the blood has different characteristics as far as the immune system is concerned, and therefore, it has substances trained for different functions. Its recommendations on food are based on the link between the digestive and immune systems, as well as the cellular and biochemical capacity to process certain elements found in meat, vegetables, fruits and grains.

The diet that feels good according to our blood group

The types of blood are divided into four large groups, being the type O, the most common, then the A, then the B and the AB that has just 5 percent of the world population.

According to Dr. D'Adamo's approach, each organism is different and, therefore, its diet can and should vary.

Dr. D'Adamo divides the diet as follows according to the blood groups:

- The group O: It is who has among its ancestors the nomad hunter of the great species, carnivore and scavenger, therefore, their diet should be based on animal protein.

- Group A: It was frequent among the first collectors of seeds, fruits and vegetables, to later cultivate them, making them more vegetarian than carnivores. However, for people of this blood group fish and shellfish are important in their diet.

- Group B: originally it belonged to a type of livestock organization, with easy access to dairy products. He was a hunter, but of small species, such as the rabbit or the partridge, at the same time he knew how to handle grains, vegetables and fruit. Individuals in group B tolerate milk, lean meats with little fat and all kinds of fruits and vegetables.

- The group AB. It is a mixture of the capacities of organisms of type A and B.

The most remarkable point of this theory is that not everyone should eat the same, since our digestive systems have specialized over time. Although it should be kept in mind that animal and vegetable proteins, whole grains, vegetables and fruits are all essential for us, we do not necessarily have to eat them in the same amount, which is a challenge in a globalized world like ours.
