In the 90s of the last century, the book "4 Blood Types: 4 Paths to Health", written by naturopathic doctor Peter D'Adamo, was published in the United States.It almost immediately became a bestseller, was translated into almost every language in the world, and became a practical nutrition guide for many people on the planet.According to the author of the book, for each blood group there is a historically correct concept of nutrition, and human health and longevity depend on it.
The main idea of this theory is that people should eat the same foods as their ancestors.It is better digested and absorbed, while the "wrong" foods clog the body.This nutritional concept is not a diet to lose weight, it is a healthy and healthy nutrition for certain groups of people, which will help cleanse and heal the body.
In fact, some studies have shown that people with different blood types are more or less susceptible to various diseases.For a long time, Dr. D'Adamo, together with his father, identified the effects of various foods on the body, so they divided them into 3 groups: beneficial, harmful and neutral.Below are lists of “good” and “bad” foods for people with each blood type.Products not listed are considered neutral and are recommended for consumption in limited quantities.
Nutrition for people with blood group I(0)
According to various sources, up to 40% of the world's population has blood from this group;Dr. D'Adamo identified them as descendants of “hunters,” so a meat diet should be more appropriate for them.

It is believed that this blood type appeared as a result of interbreeding.Dr. D'Adamo classified people gifted with it as nomads.They are expected to have the widest and most varied diet;There are fewer dietary restrictions for people with blood group III than for other people.This is explained by the fact that nomads settled on different continents and were omnivores.

Criticism of the American diet on blood type
The opinions of traditional doctors about this diet are divided, but the majority is still inclined to believe that it is not scientifically substantiated and has no scientific basis.Perhaps its only advantage is that from the list of products for people with different blood groups you can, with a little effort, create a complete and balanced diet.However, completely avoiding certain foods can lead to the depletion of certain substances in the body.For example, people of group I are almost completely prohibited from consuming dairy products, which can lead to a deficiency of calcium and phosphorus.
Many doctors agree that the blood type diet is too general and does not take into account individual characteristics of the body, lifestyle and other factors that do not depend on a person's blood type.Also, as you know, there are many more blood groups than 4;Dr. D'Adamo took one of the most simplified systems (AB0) as a basis for developing his diet.
Initially, medical books used the term "amino acids" when talking about protein products.The protein in its original form does not enter the blood;It is first broken down into amino acids.But the body, in fact, does not care from which proteins, plant or animal, these amino acids are obtained, therefore it is inappropriate to limit dairy products and meat for some categories of people.After the author of the diet pointed out this fact, the term "amino acids" was replaced by "lectins", which is not clear even to many doctors, let alone the average person.In general, many traditional doctors are inclined to believe that the book presenting this diet is "overloaded" with scientific terms, many of which are inappropriate and incomprehensible to readers.
In summary, we can say that the blood type nutrition system did not find a response in the medical community and even came under serious criticism, but the large number of positive reviews about this diet has a logical explanation.First of all, this is due to the general improvement of the diet, because strong alcohol, sweet carbonated drinks, fatty meats, many "heavy" vegetables, foods rich in saturated fats and other harmful foods are completely eliminated from the diet, regardless of blood type.In addition, one of the important factors in the positive effects of any popular diet is the placebo effect, and the development of the American doctor D'Adamo is no exception.
