Diet by blood type

The diet is based on the principles of naturopathic physician James D'Adamo, who pointed out that blood type is closely related to human nutrition. The blood type diet is based on the assumption that the composition of blood has changed during human evolution and is closely related to the type of food consumed by the vast majority of the population in a particular period.

Although there is some logic in this statement, there is no evidence-based scientific basis for separating nutrition by blood type. The following table gives some ideas on the food correspondence of people with different blood types.

1 Blood type diet

1 The positive blood type diet is based on products that mainly contain animal-derived protein in the diet. In the diet of people with this blood type, it is necessary to include low-fat varieties of red meat (beef/lamb), offal (heart, liver, lung), turkey, sea fish/river fish (herring, sturgeon, trout, halibut), Bass, salmon, mackerel, cod, sardines, pike), excluding salted fish, smoked fish and kippers.

Other products containing animal protein (dairy products, eggs) have indigestion, except for cottage cheese, which is very limited. It is recommended to use soy milk/fermented bean curd instead, but soy products can be used as a supplement, but not basic.

The blood group 1 diet includes foods that help weight loss-artichokes, Chinese cabbage, broccoli, spinach, Jerusalem artichoke, beet leaves, leeks, radishes, spinach, broccoli, parsley, garlic, horseradish, pumpkin, plums, figs. Fruit neutral vegetables include mushrooms, zucchini, white radishes, ginger, fennel, tomatoes, dill, papaya, watermelon, pears, apricots, peaches, cherries, gooseberries, and grapes.

Indigestion and not conducive to weight loss: eggplant, avocado, white/red cabbage, Brussels sprouts and cauliflower, black olives, potatoes, oranges, oranges, strawberries, strawberries, melons. Among beverages, linden/rosehip tea, plum and pineapple juice are particularly useful because they can accelerate metabolism. Chocolate, ice cream, espresso, cola, and black tea are not recommended.

Regardless of whether they have positive or negative Rh factors, dietary recommendations are provided for people with that blood type. The diet for the first Rh-positive blood type is similar to the diet for the Rh-negative blood type. The following table systematizes the list of recommended, neutral, and prohibited products for people with 1 blood type.

Diet according to the second blood type

2 The positive blood type diet is based on plant foods and is close to vegetarian food. For people with 2 positive/negative blood types, it is meaningless to include meat products in their diet because it is malabsorption and promotes fat accumulation. Sometimes you can eat neutral skinless chicken or turkey. The main sources of animal protein are seafood, fish and soy products (fermented bean curd, milk).

Especially useful are: trout, carp, pike, sea bass, white fish, cod, mackerel, sardines. It is recommended to eat fish with vegetables. Dairy products other than kefir are also unpopular in the diet. The number of eggs is 1-2 per week. Useful in grains: buckwheat, sprouted wheat berries, brown rice, and bread made from sprouted wheat berries, but you can't abuse cereal products-2-3 times a week.

The second positive blood type menu should be based on vegetables and fruits, including raw and cooked. It is particularly recommended to add broccoli, garlic, pumpkin, chicory, green beans, spinach, onions, carrots, apricots, plums, grapefruit, blackberries, strawberries, lemons, cherries, pineapples, and raspberries in the diet. According to reviews, the best results are when eating fruits grown in the area where you live. All kinds of nuts (peanuts), seeds, and green tea are very useful.

Blood type diet opinions and results

Blood group nutrition, as evidenced by the comments of individuals who practice this diet, has caused much controversy in the evidence and practical application of this theory. Therefore, it is difficult to draw a clear conclusion. People who use this diet have different opinions: some people have successfully lost extra weight, while others have not changed their weight.
