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 related. The blood type diet is based on the postulate that during the evolution of humanity, 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.

Despite the presence of some logic in this statement, there is no evidence-based scientific basis for nutrition separated by blood group. The following table gives an idea of the correspondence of food products for people with different blood groups to 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 that mainly contain 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), except salted, smoked and pickled fish.

Other products that contain 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 add-on, but not a staple.

The diet for blood group 1 includes foods that contribute to weight loss: artichoke, Chinese cabbage, broccoli, spinach, Jerusalem artichoke, beet greens, 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, currant, grape.

Poorly digested and undesirable to lose weight: aubergine, 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 helpful as they boost metabolism. It is not recommended to consume chocolate, ice cream, strong coffee, cola, black tea.

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

Diet according to the second blood group

The 2 blood group positive diet is based on plant foods and comes close to vegetarian diets. The inclusion of meat products in the diet of people who have a positive / negative blood group 2 does not make sense, since it is poorly absorbed and favors the accumulation of fat. Sometimes you can eat skinless chicken or turkey meat that are neutral. The main sources of animal protein are shellfish, fish, and soy products (tofu cheese, milk).

Especially useful are: trout, carp, pike, perch, white fish, cod, mackerel, sardine. It is recommended to eat fish along with vegetables. Dairy products, with the exception of kefir, are also undesirable in the diet. Chicken eggs in the amount of 1-2 pieces per week. Of the grains are useful: buckwheat, sprouted wheat grains, brown rice, bread made from sprouted wheat grains, but cereal products can not be abused, 2-3 times a week.

The menu of the second positive blood group should be dominated by vegetables and fruits, 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, pineapple, raspberries. According to reviews, the best effect is achieved by eating fruits that grow in the region of your residence. Various nuts (peanuts), seeds, green tea are extremely useful.

Opinions and results of the blood type diet

Nutrition by blood group, as evidenced by reviews of people who practice this diet, generates much controversy, both in terms of evidence for this theory and in its practical application. Therefore, it is difficult to draw unequivocal conclusions. The opinions of people who used this diet differ: some managed to lose extra pounds, while others did not change their weight.
