In the 1990s, 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, translated into nearly every language in the world, and became a practical nutritional guide for many people on the planet.The book's authors state that for each blood type, there is a historically correct concept of nutrition on which human health and longevity depend.
The main idea of this theory is that people should eat the same food as their ancestors.It is best digested and absorbed, whereas the "wrong" foods can clog the body.This nutritional concept is not a weight loss diet, but rather healthy, wholesome nutrition for certain groups of people that will help cleanse and heal the body.
Indeed, some studies have shown that people with different blood types are more or less susceptible to various diseases.Along with his father, Dr. D'Adamo has long identified the effects of various foods on the body and divided them into three categories: beneficial, harmful and neutral.Here's a list of "good" and "bad" foods for people with each blood type.Products not listed are considered neutral and recommended for limited consumption.
Nutrition for people with I(0) blood type
According to various sources, up to 40% of the world's population has ancestry from this group; Dr. D'Adamo believes that they are descended from "hunters" and therefore a meat-based diet should be more suitable for them.

It is believed that this blood type is the result of racial mixing.Dr. D'Adamo classifies people with this ability as nomads.People are expected to have the broadest and most varied diets; for people with blood type III, dietary restrictions are less restrictive than for others.This is because nomads settled on different continents and were omnivores.

Criticism of the American blood type diet
Traditional medicine practitioners are divided on this diet, but most still tend to believe that it has no scientific basis and no evidence base.Perhaps its only advantage is that, from the list of products suitable for people with different blood types, you can create a complete, balanced diet with a little effort.However, completely avoiding certain foods can still lead to the depletion of certain substances in the body.For example, dairy products are almost completely prohibited for people in Group I, which can lead to calcium and phosphorus deficiencies.
Many doctors believe 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.Furthermore, as you know, there are far more than 4 blood types; Dr. D'Adamo used one of the most simplified systems (AB0) as the basis for developing his diet.
Initially, doctors' books used the term "amino acid" when talking about protein products.The raw form of protein does not enter the bloodstream; it is first broken down into amino acids.But the truth is, the body doesn't care which protein, plant or animal, these amino acids are obtained from, so for certain categories of people, limiting dairy and meat isn't appropriate.The word "amino acid" was replaced by "lectin" after this fact was pointed out to the diet authors, which is not even clear to many doctors, let alone the average person.In general, many traditional medicine practitioners tend to feel that the books describing this diet have "too much" scientific terminology, much of which is inappropriate and difficult to understand for readers.
In conclusion, we can say that the Blood Group Nutrisystem did not find a response in the medical community and was even severely criticized, but the large number of positive reviews about this diet has a logical explanation.First of all, this is due to a general improvement in eating habits, since hard alcohol, carbonated sweet drinks, fatty meats, many "heavy" vegetables, foods rich in saturated fat 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 fad diet is the placebo effect, and the development of Dadamo by American doctors is no exception.
