Find out everything about the blood type diet: foods, characteristics, and theories about it.
Have you ever heard of the blood type diet? It was developed from a study of Dr. Peter D’adamo, an Italian-American scholar who theorized the relationship between diet and blood types. However, science is still skeptical about this theory. Let’s find out why and let’s try to figure out how this diet works!
What is the blood type diet
Dr. D’adamo, a supporter of the relationship between proper nutrition and evolution, created this new diet. According to his studies, each blood type has evolved in time: that is, the distinction between the different types took place during the Darwinian evolution. Therefore, each of the four existing types would be nothing more than a genetic trace that would indicate a predisposition towards certain foods, and at the same time an intolerance to other foods.
In short, depending on our blood type, we can find out which foods are most suitable for us. The goal, of course, is to follow a proper diet that regulates our metabolism and make us feel good and in shape. But is it really possible? Let’s try to understand more.
How the blood type diet works
Let’s see how the diets vary according to the blood type. For each one there is a precise diet to follow.
• Type O diet: According to D’adamo, this is the group of hunters and those who had a powerful and muscular body. People with this blood type should follow a meat-based diet, with a high content of proteins, with no grains, dairy and legumes.
• Type A diet: Farmers belong to this group. For this reason, you should follow a diet mainly based on fruits, vegetables, grains, and legumes. Meat is not recommended.
• Type B diet: This is the group of nomads, who used to move often and were characterized by a very developed immune system. For this reason, blood type B people are luckier: they can eat everything, clearly in moderation, and avoid sugars and preservatives.
• Type AB diet: This is a hybrid group, between the A and B type. For this reason, it is possible to eat pretty much everything but dairy products, which should be reduced drastically.
Does the blood type diet work?
This diet was really popular in America and later spread in the rest of the world. However, the scientific community is skeptical about it, because this diet is not based on a valid principle. On the contrary, it was developed from a indemonstrable concept, which therefore is totally incorrect.
Moreover, even if its principle were correct, there are still health risks. Let’s see what they are.
What are the risks and side effects of the blood type diet?
This food regime claims that lectins, proteins found in many types of food, should be compatible someone’s own blood type. Otherwise, there are risks of strong rejection.
This idea is based on some findings dating back to the early ’90s. Those studies suggested that the blood glycoproteins are also present in the cells lining the intestinal walls. From this it was developed the association between blood types and diet. However, without more concrete scientific evidence, this theory is based especially on ethnic and social studies. All this showed the various side effects of this diet.
Following the blood type diet, you should change your diet according to your blood type characteristics. However, this can also have negative effects: in three out of four cases (excluding the B type) one of the biggest risks is related to the almost complete absence of dairy products, which can more easily lead to osteoporosis.
According to this diet, people with blood type O should eat mostly meat, but the abuse of this food, especially red meat, can increase the risk of cancer. Blood type A people, instead, should avoid meat, but many studies showed that, in right quantities, this food is one of the main sources of proteins, iron, vitamin b12 and vitamin D.
