Diet by blood group

The diet is based on the principles of the naturopathic doctor James D'Adamo, who states that blood type and human nutrition are closely related. The blood group diet is based on the postulate that during the evolution of humanity, the composition of the blood has changed and is closely related to the type of food consumed by the vast majority of the population over a given period of time.

Despite the presence of some logic in this statement, there is no evidence-based scientific basis for separate nutrition by blood group. An idea of the correspondence of food products for people with different blood groups is given by the table below for foods by blood group.

Diet for 1 blood group

The diet for 1 positive blood group is based on the inclusion in the diet of products containing mainly proteins of animal origin. In the diet of people of this blood group, it is necessary to include low-fat 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 proteins (dairy products, chicken eggs) are poorly digested, with the exception of cottage cheese and can be consumed in very limited quantities. It is recommended to replace them with soy milk / tofu curd, however soy products can be used as a supplement, but not as a base.

The diet for blood group 1 includes foods that contribute to weight loss: artichoke, Chinese cabbage, broccoli, spinach, Jerusalem artichoke, beet leaves, leeks, radishes, spinach, broccoli, parsley, garlic, horseradish, pumpkin, plums, figs . Neutral fruit vegetables include mushrooms, zucchini, daikon, ginger, fennel, tomato, dill, quince, watermelon, pear, apricot, peach, cherry, gooseberry, grapes.

Poorly digested and undesirable for weight loss: eggplant, avocado, white / red cabbage, Brussels sprouts and cauliflower, black olives, potatoes, mandarins, oranges, strawberries, strawberries, melon. Among the drinks, lime / rosehip tea, prune and pineapple juice are particularly useful, as they speed up the metabolism. The consumption of chocolate, ice cream, strong coffee, cola, black tea is not recommended.

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

Diet according to the 2nd blood group

The menu for the second positive blood type should be dominated by fruits and vegetables, both raw and cooked. It is especially recommended to include in the diet broccoli, garlic, pumpkin, chicory, green beans, spinach, onions, carrots, apricots, plums, grapefruits, blackberries, strawberries, lemon, cherries, pineapples, raspberries. According to reviews, the best effect is achieved by eating fruits that grow in the region of residence. Various nuts (peanuts), seeds, green tea are extremely useful.

Opinions and results on the blood group diet

Nutrition by blood group, as evidenced by reviews of individuals who practice this diet, causes a lot of controversy, both in terms of the evidence for this theory and in practical application. Therefore, it is difficult to draw unambiguous conclusions. The opinions of people who have used this diet are different: some have managed to lose the extra pounds, while others have not changed weight.
