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 USA.It became a bestseller almost immediately, was translated into almost all languages of the world and became a practical guide to nutrition for many people on the planet.According to the author of the book, there is a historically correct concept of nutrition for each blood group, 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, and the "wrong" foods clog the body.This nutritional concept is not a diet for weight loss, but a healthy, wholesome diet that will help cleanse and heal the body for a certain group of people.
Indeed, some studies have shown that people with different blood types are more or less susceptible to different diseases.Dr. D'Adamo, together with his father, determined the effect of various foods on the body for a long time, and as a result divided them into 3 groups: useful, harmful and neutral.Below is a list of "good" and "bad" foods for each blood type.Products not listed are considered neutral and recommended for limited consumption.
Nutrition for people with blood type I(0).
According to various sources, up to 40% of the world's population has the blood of this group;Dr.D'Adamo identified them as a generation of "hunters," so a meat diet should be more suitable for them.

A Critique of the American Blood Type Diet
Traditional medicine doctors are divided on this diet, but the majority still tend to believe that it is not scientifically based and has no evidence base.Perhaps its only advantage is that you can create a complete, balanced diet from a list of products for people with different blood types with little effort.However, completely avoiding certain foods can still cause the body to deplete certain substances.For example, people in group I are almost completely prohibited from using dairy products, which 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 independent of a person's blood type.In addition, as you know, there are more than 4 blood groups;Dr.D'Adamo took one of the most simplified systems (AB0) as a basis for developing his diet.
Initially, the term "amino acids" was used when talking about protein products in medical books.In its original form, the protein does not enter the blood;it is first broken down into amino acids.However, the body does not really care from which proteins, plant or animal, these amino acids are obtained, and therefore it is inappropriate to limit dairy products and meat for some categories.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 the layman.In general, many traditional medicine doctors tend 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 nutritional system did not find an answer in the medical community and was even subjected to serious criticism, but there is a logical explanation for the many positive reviews about this diet.First of all, it is related to the general improvement of the diet, because strong alcohol, carbonated sweet drinks, fatty meats, 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 of the positive effect of any popular diet is the placebo effect, and the development of the American doctor D'Adamo is no exception.
