The idea of diet based on blood type belongs to the American physiotherapist Peter J. D'Adamo. Suggest a diet that will help you lose weight, improve your body and slow down aging. The idea is based on the fact that blood groups were formed during the evolution of mankind. The peculiarities of their creation depended on the products that prevailed in the diet. The essence of the system proposed by D'Adamo is the consumption of food that has shaped a certain type of people.
How the diet works for your blood type
The doctor sets out the principles of nutrition according to the dietary preferences of our ancestors in his books, which have become bestsellers. A blood type is a system of red blood cells with an antigenic identity. Recognized by the specificity of proteins and carbohydrates in cell membranes. According to the naturopath, in order to maintain the characteristics defined by nature, you should eat only foods that are suitable for the blood type.
Nutrition principles:
- preliminary tests to accurately identify your team.
- Rh factor does not play a role.
- completely exclude unhealthy foods from the diet.
- calories do not need to be measured.
- there are no restrictions on portion size.
- follow a diet for a lifetime.
The role of lectins in human nutrition
D'Adamo's theory is based on the dangers of protein components in food. They are called lectins and have the ability to bind carbohydrates to the surface of red blood cells. This process leads to accumulation of red blood cells and their precipitation. Lectins are found in large quantities in seeds, soy and wheat. These protein components can disrupt digestive processes, lead to excessive secretion of mucus in the intestines and slow down the absorption of food.
Dr. Peter says limiting the lectin diet will help improve health and prevent cancer and heart problems.
There is an alternative view. It is based on the claim that not all lectins are harmful. If not abused, they are not dangerous for the body, and some even have antineoplastic action.
Weight loss effectiveness
Diet per blood type has no scientifically proven basis, but can not be described as ineffective. Nutritionists claim that dieting according to this system helps in weight loss. They do not link weight loss with the theory proposed by D'Adamo, since changes in diet, in one way or another, will affect the body. In general, the 4 blood group diet is 4 separate designs.
They can both suit a person and prove to be harmful - it does not depend on whether he belongs to a particular type.
What you can eat per blood type
D'Adamo's idea is based on known facts about human evolution. Dietary preferences were shaped by the method of obtaining food. At the stage of hunting and gathering, meat was the main source of food. Thus blood group 1 (0 according to the AB0 system) was formed, which in Dr. Peter's theory is called "Hunters". After the introduction of man in the cultivation of vegetables and cereals, the 2nd group (A) appeared, or "Farmers".
With the beginning of the nomadic way of life and the domestication of cattle, dairy products appeared in the diet, and the third blood group was formed ("Nomads", B). When red blood cells with different antigenic characteristics were mixed, a new system emerged. It is considered the newest and most rare.
People with blood type 4 (AB) are more adapted to modern living conditions than others and in D'Adamo's theory are called "Young People".
1 group "Hunters"
The oldest blood type was formed in the time of meat eaters, when there was no other food available. For blood type 1, the healthiest food is considered to be food with a high protein content. Lean meat and poultry are the basis of the diet. Prohibited foods include pork, wheat, milk, cheese, coffee and beverages.
River fish can be eaten, but to a limited extent.
2 group "farmers"
The people who were engaged in the cultivation of crops in antiquity became the ancestors of the vegetarian direction. For the second blood group, the consumption of plant foods is allowed - bread, vegetables, fruits, legumes. Red wine and coffee are allowed. From the fish you can eat mackerel, carp and herring. All types of meat, by-products, mushrooms and milk are prohibited.
It is recommended to subject the products to minimal processing.
3 group "Nomads"
Those with blood type B are luckier than others. This group was created with a mixed lifestyle, so the list of products for its representatives is extensive. The diet for blood group 3 should be tailored to individual needs and preferences. A short list of bans includes buckwheat, corn, wheat, peanuts and chicken.
They can be easily replaced with other meat products, eggs and milk.
4 group "Young people (city people)"
People with sensitive digestion and weak immune systems have a mixed blood pattern. This group is characterized by low gastric acidity, therefore, it is necessary to refuse smoked meats, pickles and alcohol. You are allowed to eat seafood, rabbit meat, turkey, tofu, low-fat dairy products and green vegetables.
Cheese and offal are not forbidden, but should be eaten sparingly.
One-day blood group menu
There is a separate diet plan for blood groups taking into account the characteristics of the body. It is not only the antigenic characteristics that affect the daily diet, but also the state of health. If you have problems with the gastrointestinal tract, you should consult your doctor about an acceptable diet. During the treatment of chronic diseases, you should abstain from diet.
All groups are advised to drink a glass of clean water in the morning.
