The book of the American naturopathic physician Peter D'Adamo "4 blood groups - 4 paths to health" was published in the 1990s. After 10 years it was translated into all languages of the world, the book became a bestseller. The book introduced the unique experience of determining nutrition by blood type.
The author of the book claims that by choosing food according to blood type, a person reaches an ideal weight, stimulates immunity and prolongs his life. For 30 years, D'Adamo's father and son have tested products and divided them into groups depending on the effect on the human body. These groups were conventionally named so: curative, neutral and harmful.
It should be borne in mind that D'Adamo does not cite actual research, and all the criticism was erased at the request of the copyright holder of a series of books so that people would buy and keep them.
◾ Power system
The main idea of the blood group nutrition system is that each person's body is tuned to its own type of diet. In other words, "every person must eat the same food as his distant ancestors with the same blood group, otherwise the food is not completely digested and is deposited in the body in the form of fats and toxins.
The theory is based on the fact that there are 4 dominant blood groups and several groups that can be called adjoining, or borderline. The accepted international designations of blood groups are as follows:
▪ first - I (0);
▫ second - II (A), appeared as a result of mutation I (0);
▪ third - III (B), appeared as a result of the resettlement of people across the continents;
▫ fourth - IV (AB), the latest, appeared as a result of mixing II (A) and III (B).
Group I (O) - the oldest. 33, 5% of the world's population are carriers of this particular blood group.
If your blood type is 1 (0), then by D'Adamo's definition you are a descendant of "hunters".
The Hunter possesses strength, courage, intuition and energy - all the traits that helped him survive. "Hunters" are people most adapted to physical labor.
"Hunters" are usually tall, sturdy people with a square jaw. They have a high acid content in gastric juice, which promotes good digestion of animal proteins, a strong immune and digestive system. Products harmful to "hunters": wheat, beans, dark beans, corn, lentils, cabbage, cauliflower, Brussels sprouts, pork, goose meat, fish caviar, fatty dairy products, including almost all cheeses; foods high in carbohydrates (lentils, potatoes, corn, white bread). These are "foods" that slow down metabolism and, as a result, increase weight. Strong alcoholic drinks are also contraindicated for "hunters", with the exception of dry wines.
Herbal medicinal products include:
seafood »seaweed, iodized salt, red meat, liver. Vegetables include collard greens, asparagus (broccoli), spinach. These foods speed up the metabolism and therefore reduce weight.
◽ "Neutral" foods for "hunters" are:
▪ meat: lamb, beef »beef heart;
▫ fatty fish: halibut, perch, salmon, sturgeon, sardine;
▪ linseed and olive oils;
▫ figs, plums (including prunes), walnuts »pumpkin seeds.
Group II (A), then you are a descendant of "farmers". Representatives of this blood group make up 37.8% of the world's population. Unlike "hunters", "farmers" suffer from low acidity of gastric juice. Ideally, their diet should consist of plant-based foods, in other words, D'Adamo recommends them to be completely vegetarian.
Treatment products for this category of people are as follows:
carp, perch, cod, salmon, mackerel, whitefish; soy milk and cheese, lemon, apricots, pineapples, lingonberries, cherries, blueberries, figs, cranberries, raisins, plums and prunes, blueberries, olive oil, peanuts, pumpkin seeds, beans, peas, lentils, buckwheat, and coffee are also useful, green tea ”herbal teas, red wine, water with lemon juice, carrot, pineapple, grapefruit, cherry juices. All of these foods speed up the metabolism and thus "contribute to weight loss."
◾ "Neutral" products are:
▪ meat: turkey »chicken;
▫ fish: sea bass, sturgeon, pike;
▪ homemade cheese, yogurt, kefir, goat's milk and cheese, processed cheese, cod liver;
▫ walnuts, pine nuts and almonds, sunflower seeds;
▪ from berries - currants and gooseberries, from fruits - peaches, dates, apples.
The diet of the "farmer" should be rich in vitamins of group B, C, E, calcium, iron, zinc, selenium, chromium.
◽ Foods that D'Adamo believes are harmful to the "farmers":
▪ beef, veal, pork, rabbit, goose, mutton, lamb, partridge, pheasant, beef heart;
▫ salinity and smoked meats;
▪ all seafood;
▫ butter, ice cream »whole milk, peanut, corn, cottonseed oil;
▪ fatty cheeses;
▫ beans, eggplants, cucumbers;
▪ oranges and orange juice, tangerines, rhubarb, papaya, melon, bananas;
▫ black tea, all soda drinks.
According to D'Adamo, they slow down the metabolism of "farmers", which leads to weight gain.
Blood of group II (III? After all, further (B)!) (B) indicates that you are a descendant of "nomads". 20.6% of the world's population are carriers of this particular blood group. They are broad-boned, muscular, long-legged, often red-haired or green-eyed people. They are calm, optimistic, distrustful, quick-witted. The type arose as a result of the dispersal of races. It is characterized by a strong immune system, a balanced nervous system, and developed adaptive mechanisms. Like their distant ancestors, modern “nomads” are “omnivorous”.
However, corn, wheat, lentils, peanuts and buckwheat slow down the metabolism in the body of the "nomad". These foods are difficult to digest and lead to excess weight. You should switch to green salads, eggs, liver, soy, licorice root decoction. For "nomads" the following products will be medicinal: mutton, lamb, rabbit, venison; fatty fish, black caviar, high-fat dairy products, carbohydrate-rich foods, eggplant, carrots, beets, parsley, broccoli.
◾ "Neutral" for "nomads" are:
▪ red meat (beef, veal, etc.), turkey and pheasant;
▫ smelt, carp, herring, cod liver;
▪ soy milk and soy cheese;
▫ hard cheeses;
▪ linseed oil, walnuts and almonds;
Harmful products for this type of people are:
pork, duck, goose, chicken, partridge, quail, beluga, crabs, shrimps, crayfish, ice cream, peanuts, pine nuts, sunflower seeds, pistachios, hazelnuts and black bread.
Carriers of IV blood group (AB) are called "new people". This is a mixed type, it includes 7-8% of the world's population. This is the most difficult group, since it incorporates the features of two groups — I (0) and P (A). The type is focused on meat food, which becomes a problem with low acidity of the stomach, so the menu of the "new people" is not easy.
Foods from which the "new people" gain weight: red meat, beans, lentils, corn, buckwheat, wheat.
◽ Treatment products:
▪ lamb, rabbit meat, turkey;
▫ salmon, sturgeon, mackerel, cod, sardines;
▪ homemade cheese, yoghurts, goat milk, pressed cottage cheese, sour cream;
▫ walnuts, peanuts, olive oil, red beans, lentils, oatmeal;
▪ eggplant, collard greens, broccoli, cauliflower, beets, celery, garlic;
▫ pineapple, grape, grapefruit, cherry, cranberry, gooseberry, grape, plum, lemon.
◾ "Neutral" products for "new people":
▪ pheasant, any liver;
▫ fish, red and black caviar, as well as mussels and cod liver;
▪ low fat milk and low fat dairy products;
▫ soy cheese and milk;
▪ hard cheeses;
▫ cereals high in carbohydrates;
▪ apricots, pear, melon, peaches, dates, tangerines, prunes, apples;
▫ watermelon, lingonberry, blueberry, blueberry, blackberry, and raisins;
▪ wine and beer.
◽ Not recommended for “new people”:
▪ pork, beef, venison, goose, chicken, partridge, quail;
▫ flounder, crabs, shrimps, crayfish, herring, eel;
▪ dairy products with a high fat content: butter, ice cream, whole milk;
▫ corn, sunflower, cottonseed oils;
▪ beans and black beans;
▫ buckwheat, corn, artichokes, hot peppers, olives, radish;
▪ avocado, orange, tangerine, bananas, pomegranates, mango, persimmon, linden flower tea.
There is one weak point in the blood type nutrition system. Soon after the publication of D'Adamo's book, it became clear that there are many more blood groups than four. This is due to many reasons: with the Rh factor, with wave fluctuations and other facts discovered by science. D'Adamo did not redistribute interest and rebuild the system for the sake of these "unaccounted for" groups, especially since they were carriers of the same blood groups, only with their own distinctive features.
These features, according to D'Adamo, had external signs.
Muscular, narrow-hipped, broad-shouldered representatives of the species Homo sapiens. The blood type can be any. Courage and enterprise often lead to injury. Researchers are highly sensitive to caffeine, alcohol, and pain relievers. The diet for the "researchers" corresponds to the blood group I diet, and should also include foods rich in copper, such as lamb and beef liver, soft cheeses, parsnips, lentils, ginger, and raspberries.
Flexible, wiry, by nature calm people, persistent ”with good immunity. In their veins, blood flows from II (A) group or IV (AB). The teachers' diet should contain pork, poultry (turkey) and white fish, as well as plant products: beans, green peas, peanuts, flaxseeds, avocados, carrots. Olive oil should be preferred. Avoid foods high in carbohydrates (sweet, starchy foods), lamb and beef.
Blood of group P (A) or IV (AB). Tall, slender people in their youth, become obese over the years.
Charismatic, witty people who find it difficult to relax blush quickly. The Warriors' diet consists of low glycemic plant foods: peanuts, pine nuts, soy, nut butter, cauliflower, as well as fish and cottage cheese. Foods with a high carbohydrate content are not recommended: white bread, pasta and flour products. You should limit yourself to meat.
◾ Diet recommendations for blood type
According to D'Adamo, a metabolic disorder occurs in the human body that does not follow these simple rules. Outwardly, this is usually expressed in the fact that a person is gaining weight.
Diseases of internal organs are also inevitable. If you eat, as D'Adamo prescribes, then the body is cleansed of toxins, metabolic processes are enhanced, the work of internal organs, cleansing and excretory systems improves, and a person loses weight. Of course, it will take time, because the body needs to rebuild its work, so for those who want to get instant results, this diet is not suitable .. There are several caveats that should be remembered for those who want to lose weight using this method. Surely many who are not familiar with the blood type diet, after reading it, will be surprised that their taste preferences coincide with the recommendations of a nutritionist. This riddle has a simple explanation: the body knows itself what will harm it and what will benefit it. You just need to listen to his prompts.
The Peter D'Adamo Method is not a weight loss diet. This is a system for cleansing and healing the body. It makes joints work better, improves tone, improves skin color and well-being.
The author considers several blood groups, while there are several dozen blood group systems in people living on the planet. Listen to your desires. If you don't want to eat meat or green salad - don't eat! When switching to a new food system, take your time, introduce new dishes into your diet gradually. This will help the body avoid stress. There is no need to turn recommendations into instructions. Diet is not a dogma. You need to approach it creatively, look for your own way of life. It will be more beneficial if you eat what you are used to, just reduce the portion.
By the way, the opponents of the doctor believe that all the tests carried out by him are unproven from a medical point of view and have no clinical observations, and especially irreconcilable witty remarks that with the same success it is possible to create a diet based on gender.
In addition, traditional medicine is wary of Peter D'Adamo's theory, believing that much remains beyond science in the study of blood groups. Medicine does not dare to claim that a blood type diet leads to any definite results. Doctors avoid specific wording, saying that the system is designed for healthy people. Therefore, before giving preference to the D'Adamo method, it is not enough to donate blood for analysis. Visit an endocrinologist, gastroenterologist, allergist, and dermatologist.
