Diet according to blood type (1,2,3,4): positive and negative Rh factor, food, table

General rules

The diet is based on the principles of naturopathic physician James D'Adamo, who argues that a person's blood type and nutrition are closely interrelated.
The blood type diet is based on the postulate that in the process of human evolution, the composition of the blood changed and was closely correlated with the type of food consumed by the vast majority of the population of a particular time period. At different stages of human evolution, different methods of social labor prevailed (hunting, farming, domestication of wild animals), which formed the basis of their diet (meat, plant foods, dairy products) and the type of metabolism. Accordingly, according to the author, the composition of the blood also changed (groups I, II, III and IV). It is on this statement that blood group nutrition is built, the essence of which is the need to include in the diet of a person with a specific blood group food products that correspond to it and exclude/minimize foods that do not correspond to it.

Despite the presence of a certain logic in this statement, there is no evidence-based scientific basis for separate nutrition according to blood groups. However, it is impossible to categorically state that this is the right diet or the wrong one, since the blood type diet is more or less balanced in the main food nutrients and, unlike various kinds of strict mono- and express diets, is soft and designed for a long period, which suggests a lasting effect. Some idea of the suitability of food products for people with different blood types is given by the table below of nutrition by blood types.

Diet according to blood group 1

The diet for 1 positive blood group is based on the inclusion in the diet of mainly products containing proteins of animal origin. The diet of people of this blood type must include lean varieties of red meat (beef/lamb), offal (heart, liver, lungs), turkey meat, sea/river fish (herring, sturgeon, trout, halibut, perch, salmon, mackerel, cod , sardine, pike), excluding salted, smoked and pickled fish.

Other products containing animal protein (dairy products, chicken eggs) are poorly digestible, with the exception of cottage cheese and can be consumed in very limited quantities. It is recommended to replace them with soy milk/tofu, but soy products can be consumed as additional, but not main ones.

Additional sources of protein include seeds (pumpkin seeds) and walnuts. It is mandatory to include olive and flaxseed vegetable oils in the diet, avoiding corn, peanut and cottonseed oil. It is useful to include seaweed and red wine in your diet. Persons with the first blood group are advised to avoid eating white wheat bread, corn, oatmeal, millet and wheat cereals, replacing these products with rye bread, rice bread, buckwheat and barley cereals.

The diet for blood type 1 includes foods that promote weight loss - artichoke, Chinese cabbage, broccoli, spinach, Jerusalem artichoke, beet leaves, leeks, radishes, spinach, broccoli, parsley, garlic, horseradish, pumpkin, plums, figs. Neutral fruits and vegetables include mushrooms, zucchini, daikon, ginger, fennel, tomatoes, dill, quince, watermelon, pears, apricot, peach, cherry, gooseberry, and grapes.

Poorly digested and undesirable for weight loss: eggplants, avocados, white/red cabbage, Brussels sprouts and cauliflower, black olives, potatoes, tangerines, oranges, strawberries, wild strawberries, melon. Among the drinks, linden/rosehip tea, plum and pineapple juice are especially useful, as they speed up metabolism. It is not recommended to consume chocolate, ice cream, strong coffee, cola, and black tea.

From the vegetable group, the diet of the first group should include Chinese cabbage, artichoke, Jerusalem artichoke, spinach, leek, garlic

Nutritional recommendations for people with this blood group are given regardless of whether they have a positive or negative Rh factor. Nutrition for the first Rh-positive blood group is similar to nutrition for the Rh-negative blood group. Below is a table systematizing the list of recommended, neutral and prohibited products for people with blood type 1.

Diet according to blood group 2

The diet for positive blood group 2 is based on products of plant origin and is close to vegetarian diets. Including meat products in the diet for people with positive/negative blood type 2 does not make sense, since it is poorly digestible and promotes fat accumulation. Sometimes you can eat skinless chicken or turkey, which are neutral. The main sources of animal protein are seafood, fish and soy products (tofu cheese, milk).

Particularly useful include: trout, carp, pike, perch, whitefish, cod, mackerel, sardine. It is recommended to eat fish together with vegetables. Dairy products, with the exception of kefir, are also not advisable in the diet. Chicken eggs in the amount of 1-2 pieces per week. Healthy cereals include: buckwheat, sprouted wheat grains, brown rice, bread made from sprouted wheat grains, but you should not overuse cereal products - 2-3 times a week.

All soy products are especially beneficial for the second blood group.

The menu for the second positive blood group should be dominated by vegetables and fruits, both raw and cooked. It is especially recommended to include broccoli, garlic, pumpkin, chicory, green beans, spinach, onions, carrots, apricots, plums, grapefruit, blackberries, strawberries, lemon, cherries, pineapple, and raspberries in your diet. According to reviews, the best effect is achieved by consuming fruits that grow in the region where you live. Various nuts (peanuts), seeds, and green tea are extremely beneficial.

Dietary food for the second blood group allows the use of olive/linseed vegetable oil as fats; it is recommended to exclude animal fats from the diet altogether. In moderation and no more than 3 times a week, you can drink red table wines after meals. A generalized table of recommended, neutral and prohibited foods for people with blood type 2 is given below.

Diet according to blood group 3

The diet for positive blood group 3 includes a fairly diverse set of foods. Persons with 3 positive/negative blood type are relatively “omnivores” and can consume most meat and dairy products (except pork and chicken), lean fish, eggs, cereals (except wheat and buckwheat), mushrooms, legumes and almost all types vegetables/fruits, with the exception of olives, corn, pumpkins, tomatoes.

Undesirable products are crustaceans and various types of mollusks, fish caviar, waterfowl eggs, sunflower oil, nuts and seeds, food gelatin, legumes, cheese, ice cream. Equally important for weight loss is the balance of eating different types of grains.

For people with blood type 3, the diet includes veal, chicken, rabbit, lamb and game

By excluding buckwheat/corn groats from the diet, the amount of other types of grains should be minimal. From the list of vegetables and fruits, it is necessary to exclude radishes, radishes, eggplants, pomegranates and persimmons, avocados, as well as some spices - white / black pepper.

Dry red/white wine is allowed. Nutrition for the third blood group, as evidenced by reviews of those practicing such a diet, is complete and easily tolerated. The table below gives an idea of the diet of people with this blood type.

And wheat in the diet for weight loss may be present in limited quantities or completely excluded. Among vegetables, tomatoes and potatoes, which are undesirable in the diet of other groups, are optimal, and radishes, artichokes and bell peppers should be excluded.

Basic principles

It has been proven that excess weight and many diseases in 90% of cases are the result of poor nutrition. Having heard from a doctor the phrase that you need to follow a diet, many patients fall into despair, because for most of them it is quite difficult to limit themselves in nutrition. The blood type diet helps you lose extra pounds and prevent the development of various diseases without much difficulty. The patient does not have to count calories and give up favorite foods. All you need to do is exclude only some foods from your diet, and the desired result will not take long to arrive.

American physician James D'Amado, as a result of his many years of research, suggested that each blood group has its own positive, negative and neutral products. The scientist argued that dishes that are healthy for some people can be harmful to other patients. Based on this, we can conclude that nature itself tells a person what kind of food he should eat.

Reviews of the blood type diet and results

Nutrition according to blood groups, as evidenced by reviews from people who practice this diet, causes a lot of disagreement, both in terms of evidence for this theory and in practical application.

“...The blood type diet interested me and my friend almost a year ago. We read various information on the Internet and decided to try it, despite the fact that reviews from doctors were generally negative. It was the hardest for me, since I have a positive blood type 2 and I had to change my usual diet to a greater extent. I can’t consider myself a meat-eater, but, nevertheless, I really love and often eat chicken dishes. I had to give up a lot and switch to more plant-based foods. The fish helped a little. I didn’t like soy products and tofu cheese at all; I got used to eating yogurt every day. To be honest, I barely made it through one month, because I had intestinal problems from the large amount of fiber. The results are not so hot - 2.7 kg. For my friend, everything was easier because she has a positive blood type 3 and her diet was much wider and did not require any special adjustments to her diet. She only had to adjust it a little. She has been following this diet for three months now, and although she hasn’t lost as much weight in two months as she wanted and she still needs to lose 5 kg before her goal, her health has improved significantly, as has the condition of her hair and skin.”

Special power system

It is difficult to say when the idea of building a nutritional system based on erythrocyte hereditary characteristics first appeared.

But the starting point was the release of a book by Peter D'Adamo devoted to studying this issue. The book was published in 1990 and immediately won everyone's attention. More than a quarter of a century has passed, and the theory of nutrition based on group division is still relevant. Thousands of people around the world are guided by the principles of a healthy lifestyle.

The essence of the method, voiced by an American naturopath, is that there is no single nutritional system that would be ideal for the entire population of the planet. Over millions of years of evolution and formation of the immune system of the human body, a certain ability to assimilate some foods better than others has developed.

People's lives were also not identical. There were different areas of human activity, the first of which were agriculture and hunting. At present, according to d'Adamo, the descendants of ancient farmers are more adapted to assimilate food of plant origin than of animal origin. The recommendations collected for creating a daily diet are accessible and understandable to everyone. The general principles of the nutrition system are divided into four groups.
