The idea of nutrition based on blood type came from the American doctor of naturopathy, Peter J. D'Adamo. He proposed a diet that would help you lose weight, improve your body, and slow down aging. The concept is based on the fact that blood groups formed during the evolution of mankindThe features of their manufacture depended on the products prevalent in the diet. The essence of the system proposed by D'Adamo is the consumption of food that constituted a specific type of people.
How does the blood type diet work
Doctors set forth the principles of nutrition based on the food preferences of our ancestors in his books, which have become bestsellers. A blood group is a system of red blood cells with an antigenic identity. Its identity is the proteins and carbohydrates in cell membranes. According to naturopaths, to maintain the characteristics prescribed by nature, one should eat only that food which is suitable for the blood group.
Diet Principle:
- Pre-pass test to accurately determine your group;
- The Rh factor does not matter;
- completely exclude unsuitable foods from the diet;
- No need to count calories;
- There are no portion size restrictions;
- Stick to the diet for life.
The role of lectins in human nutrition
D'Adamo's theory is based on the dangers of protein components in foods. They are called lectins and have the ability to bind to carbohydrates on the surface of red blood cells. This process leads to clumps and precipitation of red blood cells. Lectins are found in large amounts in seeds, soybeans and wheat. These protein components can disrupt digestive processes, lead to excess secretion of mucus in the intestines and slow down the absorption of food.
Dr. Peter says restricting the diet to lectins will help improve health and prevent cancer and heart problems.
There is an alternative approach. It is based on the claim that not all lectins are harmful. If they are not abused, they are not dangerous to the body, and some even have antitumor activity.
weight loss effectiveness
Nutrition by blood group has no scientific evidence base, but it cannot be called ineffective. Nutritionists claim that dieting according to this method helps in losing weight. They call weight loss by D'AdamoDo not add to the proposed theory, because a change in diet, one way or another, will affect the body. In total, the 4 blood group diet is 4 different plans.
They can both suit a person and be harmful - it does not belong to his particular type.
what can you eat according to blood group
D'Adamo's concept is based on well-known facts about human evolution. Food preferences were formed based on the method of obtaining food. In the hunting and gathering phase, meat was the main source of food. Thus blood group 1 (0) were formed according to the AB0 system, called "hunters" in Dr. Peter's theory. The second group (A), or "peasants", appeared after the introduction of man to the cultivation of vegetables and grain crops.
With the beginning of the nomadic lifestyle and the domestication of cattle, dairy products appeared in the diet, and the third blood group ("nomads", b) was formed. When red blood cells with different antigenic characteristics were mixed, a new systememerged. They are considered the smallest and rarest.
Individuals with blood group 4 (AB) are more adapted than others to modern living conditions, and are called "new people" in D'Adamo's theory.
1st group "Hunters"
The most ancient type of blood was made during the time of carnivores, when no other food was available. The healthiest food for blood group 1 is considered to be high-protein. Lean meat and poultry form the basis of the diet. Among the forbidden foods are pork. Contains meat, wheat, milk, cheese, coffee and alcohol.
River fish can be consumed, but in limited quantities.
2nd group "Farmers"
People who were engaged in the cultivation of crops in ancient times became the ancestors of the vegetarian direction. For the second blood group, it is allowed to eat plant foods - bread, vegetables, fruits, legumes. Red wine and coffee are allowed. From fish you can eat mackerel, carp and herring. All kinds of meat, offal, mushrooms and milk are prohibited.
It is recommended to subject products to a minimum of processing.
3rd group "Nomad"
People with type B blood are more fortunate than others. This group was created with a mixed lifestyle, so the list of products for its representatives is extensive. The blood type 3 diet should be tailored to individual needs and preferences. ProhibitionsA short list of these include buckwheat, corn, wheat, peanuts and chicken.
They can be easily replaced with other meat products, eggs and milk.
4 group "New people (towners)"
People with sensitive digestion and weakened immunity have a mixed blood pattern. This group is characterized by low gastric acidity, so it is necessary to refuse smoked meats, pickles and alcohol. Seafood, rabbit meat, turkey meat, tofu, lessIt is allowed to eat fatty dairy products and green vegetables.
Cheese and offal are not prohibited, but they should be eaten only occasionally.
