The idea of ​​nutrition based on blood type belongs to the American doctor of naturopathy, Peter J. D’Adamo. He proposed a diet that will help to lose weight, improve the body, slow down aging. The concept is based on the fact that blood groups formed during the evolution of mankind. The features of their creation depended on the predominant products in the diet. The essence of the system proposed by D’Adamo is the use of food, which formed a specific type of people.

How does a blood type diet work?

The doctor outlines the principles of nutrition, depending on the nutritional preferences of our ancestors, in his books, which have become bestsellers. Blood type is a red blood cell system with antigenic identity. It is identified by the specificity of proteins and carbohydrates in cell membranes. According to the naturopath, in order to maintain the characteristics laid down by nature, you should eat only food suitable for the blood group.

The principles of diet:

• pre-pass tests to accurately determine your group;
• the rhesus factor does not matter;
• completely eliminate unsuitable foods from the diet;
• Calories should not be counted;
• no portion size restrictions;
• stick to a diet all my 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 carbohydrates on the surface of red blood cells. This process leads to the adhesion of red blood cells and their precipitation. Lectins are found in large quantities in seeds, soybeans, 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 argues that limiting lectin diets will help improve health, prevent cancer and heart problems..

There is an alternative point of view. It is based on the assertion that not all lectins are harmful. If not abused, they are not dangerous for the body, and some even have antitumor activity.

Weight Loss Efficiency

Nutrition in the blood group does not have a scientific evidence base, but it cannot be called ineffective. Nutritionists say that dieting on this system helps to lose weight. They do not associate weight loss with the theory proposed by D’Adamo, as changes in the diet, one way or another, will affect the body. By and large, the diet of 4 blood groups is 4 separate plans.

They can both suit a person and be harmful – it does not depend on his belonging to a particular type.

What can I eat by blood type

The concept of D’Adamo is based on well-known facts about the evolution of man. Food preferences were formed depending on the method of food extraction. At the stage of hunting and gathering, the main source of food was meat. So 1 blood group was formed (0 according to the AB0 system), which in the theory of Dr. Peter is called “Hunters”. After the person was introduced to the cultivation of vegetable and grain crops, the 2nd group (A), or “Farmers”, appeared.

With the onset of a nomadic lifestyle and the domestication of cattle, dairy products appeared in the diet, and a blood group 3 was formed (Nomads, B). When red blood cells with different antigenic characteristics were mixed, a new system arose. She is considered the youngest and rarest..

Persons with 4 blood groups (AB) are most adapted to modern living conditions and in the theory of D’Adamo are called “New People”.

1 group “Hunters”

The most ancient type of blood was formed during the time of meat-eaters, when there was no other available food. For the 1st blood group, the most healthy food is high-protein. Lean meat and poultry form the basis of the diet. Prohibited foods include pork, wheat, milk, cheeses, coffee, and spirits..

River fish can be consumed, but to a limited extent.

2 group “Farmers”

People engaged in the cultivation of crops in antiquity became the progenitors of the vegetarian trend. For the second blood group, it is allowed to eat plant foods – bread, vegetables, fruits, and legumes. Red wine and coffee are allowed. From fish you can eat mackerel, carp and herring. All types of meat, offal, mushrooms and milk are prohibited..

Minimum processing is recommended..

3 group “Nomads”

Type B blood holders are more fortunate than others. This group was formed with a mixed lifestyle, so the list of products for its representatives is extensive. Diet for type 3 blood should be made taking into account individual characteristics and preferences. A short list of bans includes buckwheat, corn, wheat, peanuts and chicken.

They can easily be replaced with other meat products, eggs and milk..

4 group “New people (citizens)”

People with sensitive digestion and weak immunity have a mixed nature of blood. Low gastric acidity is inherent in this group, therefore it is necessary to refuse smoked meats, pickles and alcohol. Seafood, rabbit, turkey, tofu, low-fat sour-milk products and green vegetables are allowed.

Cheeses and offal are not prohibited, but they should not be eaten often..

One-day blood group menu

A separate diet plan for blood groups is made taking into account the characteristics of the body. Not only antigenic characteristics affect the daily menu, but also the state of health. In case of problems with the gastrointestinal tract, it is necessary to consult a doctor about the acceptable diet. For the treatment of chronic diseases should refrain from diet.

For all groups it is recommended to drink a glass of clean water in the morning.

A sample menu for one day for “hunters”:

• Breakfast: toast with peanut butter, 1 banana, a glass of tomato juice.
• Lunch: fruit salad of grapes, pears, apples.
• Dinner: baked beef, fresh herbs, apple.
• Afternoon snack: a handful of walnuts, a glass of cherry juice.
• Dinner: cod cutlets, beetroot salad.

Daily ration for “farmers”:

• Breakfast: fruit yogurt.
• Lunch: feta cheese, lettuce.
• Dinner: salmon steak in lemon sauce with tomatoes.
• Afternoon snack: low-fat cottage cheese dessert, tea.
• Dinner: baked vegetables.

One-day menu for “nomads”:

• Breakfast: oatmeal with apples, mint tea.
• Lunch: prune with nuts, ginger drink.
• Dinner: cabbage cream soup with mushrooms.
• Afternoon snack: pea puree, green pepper.
• Dinner: lamb stew with vegetables.

Daily meal plan for “citizens”:

3. Lasting effect. The diet is correctly balanced for the main trace elements, food compatibility of products for each individual blood group is good, therefore, the proposed nutrition plan can be followed for a long time.
4. Acceleration of Metabolism. The transition to proper nutrition and the introduction of protein in the diet always helps to accelerate a slow metabolism.
5. Health improvement. A blood test diet with the right approach has a positive effect on immunity and helps to eliminate toxins..

Risks and contraindications

1. Deficiency of some nutrients. Restrictions for certain groups (more for 1 and 2) can lead to a lack of calcium, therefore, during the diet, vitamins and dietary supplements must be taken to maintain the body.
2. Excess protein. This is more related to group 1. High protein intake with frequent meat consumption can lead to heart problems..
3. There are contraindications. The diet is not suitable for pregnant and lactating women, people with severe chronic diseases.
