Diet by blood type

The diet is based on the principles of naturopathic physician James D'Adamo, who states that blood type and human nutrition are closely interrelated. The blood type diet is based on the postulate that during the evolution of mankind, the composition of the blood changed and closely correlated with the type of food consumed by the overwhelming majority of the population of a particular time period.

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

Diet for 1 blood group

The diet for 1 positive blood group is based on the inclusion in the diet of mainly products containing 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 protein (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 an additional, but not basic.

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. Fruit neutral vegetables include mushrooms, zucchini, daikon, ginger, fennel, tomato, dill, quince, watermelon, pear, apricot, peach, cherry, gooseberry, grape.

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

Diet recommendations for people with this blood group 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 group.

Therefore, it is difficult to draw unambiguous conclusions. The opinions of people who used this diet differ: some managed to lose extra pounds, while others did not change their weight.
