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.Almost immediately it became a bestseller, was translated into almost all languages of 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 accurate concept of nutrition, and human health and longevity depend on it.
The main idea of this theory is that people should eat the same food as their ancestors.It is best digested and absorbed, while "wrong" foods block the body.This food concept is not a diet for weight loss, it includes healthy and wholesome food for certain groups of people, which will help to cleanse and heal the body.
Indeed, some studies have shown that people with different blood types are more or less susceptible to different diseases.For a long time, Dr. D'Adamo, together with his father, identified the effects of various foods on the body, as a result of which they were divided into 3 groups: useful, harmful and neutral.Below are lists of "good" and "bad" foods for those with each blood type.Products not listed are considered neutral and recommended for consumption in limited quantities.
Nutrition for people with blood type I(0).
According to various sources, up to 40% of the world's population has blood of this group;Dr.D'Adamo identified them as descendants of "hunters", so a meat diet should be more suitable for them.

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

Critique of the American Blood Type Diet
The opinions of traditional medicine doctors about this diet are divided, but the majority is still inclined to believe that it is not scientifically proven and has no evidence base.Perhaps its only advantage is that from the list of products for people with different blood groups, you can create a complete and balanced diet with some effort.However, completely avoiding certain foods can still lead to the depletion of certain substances in the body.For example, people with group I are almost completely forbidden to consume dairy products and this can lead to calcium and phosphorus deficiency.
Many doctors agree that the blood type diet is too general and does not take into account the individual characteristics of the body, lifestyle and other factors that do not depend on a person's blood type.In addition, as you know, there are many more blood types than 4;Dr.D'Adamo took one of the most simplified systems (AB0) as the basis for developing his diet.
Initially, the doctor's books used the term "amino acids" when talking about protein products.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, and therefore it is inappropriate to limit dairy and meat products for certain categories of people.After this fact was pointed out to the author of the diet, the term "amino acids" was replaced by "lectins", which is not clear even to many doctors, let alone to the average person.In general, many doctors of traditional medicine are inclined to believe that the book presenting this diet is "overloaded" with scientific terms, many of which are inappropriate and incomprehensible to readers.
To summarize, we can say that the blood group nutrition system did not find an answer in the medical community and was even subjected to 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 meat, many "heavy" vegetables, foods rich in saturated fats and other harmful foods are completely removed 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.
