3 basic principles of the blood type diet

Blood can tell a lot about a person because it is essentially the carrier of life and destiny. Did you know that there was even a blood type-based diet that was very fashionable for a while? Some fatties are still interested in this and study the list of allowed products.

It should be said right away that this technique has been criticized by doctors more than once and has no scientific basis. But the forewarned is forearmed, so let's try to learn everything about this diet.

History of the diet

Once upon a time, people believed that everyone had the same blood. Do you remember the fairy tale about Mowgli? "You and I are of the same blood - you and I! "But soon after they tried to share their blood with the sick and injured, a theory emerged that the blood was actually different.

Many scientific studies and experiments were carried out with animals and humans, but only in 1900 three blood groups were discovered by Karl Landsteiner, and soon the fourth was discovered by his students.

Currently the world has adopted an alphanumeric classification:

• Him or me – first;
• A (II) – second;
• B(III) – third;
• AB (IV) – fourth.

The most common blood groups in the world are the first and second blood groups. Its carriers constitute 80% of all humanity. The third is less common, found in 15%, and the fourth is considered the rarest and is represented by only 5%.

American naturopathic physician Peter D'Adamo suggested in the late twentieth century that if some human diseases are directly related to genetic traits and are often linked to blood type, blood type nutrition might also be possible. He asked each of his patients about their preferences for certain foods and compiled the right diet for each group. All products were divided into useful, undesirable and neutral.

D'Adamo has written several books on diet. They were a huge success with American readers and became bestsellers. Then the concept of "4 blood groups - 4 paths to health" spread all over the world, and everyone who wanted to lose weight rushed to try the new diet.

What's that?

Basic principles and rules

Nutrition according to blood groups is as follows.

• In every period of human evolution, there was a certain nutritional pattern, and as it changed, the blood also mutated and a new group emerged. Therefore, there is a basic set of products for each group.
• To keep your body in tip-top shape, you need to eat the way your ancestors did with a particular blood type. Thanks to the biochemical connection between blood and food, the "right" foods are better absorbed, digested faster, speed up the metabolism and strengthen the immune system.
• If you remove the "wrong" foods from your diet, you can increase the body's performance, improve health and extend life.

An example of this is moving to another living space, even tourism, when the local unusual cuisine is not accepted by the body and health problems begin.

If a resident of the Far North, who has been eating fatty protein foods all his life, decides to move to Europe with its carbohydrate-rich cuisine, then there is a high risk of diabetes and digestive problems.

You don't even have to go far for examples, just look around. Some people hate dairy, some prefer plant-based foods, and others go hungry if they don't eat a large piece of meat. Maybe this is not without reason?

General dining table for all groups

Dr. divides foods according to blood type and emphasizes those that are prohibited, allowed and neutral. Let's get to know D'Adamo's research.

Myth:

• Products that need to be restricted are indicated with a "-" sign;
• allowed – "+";
• neutral – "0".

Nutrition according to blood type 1

The most common in the world is the first positive blood group. It is most often found among Eastern Slavs and American Indians.

People with the first blood group are universal donors, that is, this blood type is suitable for absolutely everyone. By the way, mosquitoes prefer the first blood group over others.

Features of eating behavior (hunter, meat eater)

All ancient people living in a primitive communal system had absolutely the first blood type, and everything else occurred through mutation.

Now remember the history of the Ancient World, archaeological excavations and the conclusions of scientists - 40, 000 years ago primitive people lived by hunting and gathering. Their main diet consisted of meat, meat, and more meat, and only then roots, herbs, and a few edible fruits and nuts that grew wild in the forests.

Thus, the owners of the first group carry the genes of the most ancient predators, and their body at the gene level requires as much protein as possible. The diet, unfortunately, is the poorest. If you decide on such a diet, you will have to give up most of your favorite foods.

The diet of the first blood group includes meat, fish and vegetables. It is better not to consume milk and its derivatives at all.

Nutrition according to blood group 2

There is no less common group. It is literally several hundred years younger than the first one and was formed by mutation after ancient hunters decided to settle permanently and engage in agricultural work.

People with blood type 0 produce more of the hormone cortisol, which helps cope with stress. They are also unfortunately prone to alcoholism.

Features of eating behavior (farmer)

25, 000 years ago, meat-eating hunters learned to work the land and receive its gifts. This is the very beginning of the development of the agricultural way of life. People began to build settlements, cultivate fields, and plant grain crops and vegetables.

Protein foods decreased, animals moved away from humans, and meat became harder to obtain.

Sometimes the second blood group is called "vegetarian". Most of its speakers live in Europe.

The diet of people with the second blood group should include vegetarian dishes, fish, poultry and dairy products. However, it is recommended to give up coffee, beans and meat.

Nutrition according to blood group 3

The third group is quite rare and more characteristic of Asian peoples - in the old days they were famous for their large herds of animals such as horses, cows, goats and sheep. Of course, they had to move from place to place to feed the animals.

Features of eating behavior (nomadic)

As soon as milk and dairy products began to be actively included in the diet, and this happened about 10, 000 years ago, blood mutated again.

The largest number of people with the third blood group lives in Asia - these are hereditary nomads.

Such people are the luckiest; They have almost no restrictions, they are omnivores. It is necessary to exclude semi-finished products, smoked meats and alcohol.

Nutrition according to blood type 4

The fourth group was formed by mixing the second and third groups after people started living in large settlements and cities.

People with blood type IV are more likely to suffer from senile dementia and Alzheimer's disease. However, they are also universal donors of plasma, which is very valuable in burn treatment.

Features of eating behavior (mystery)

This blood is the youngest, its age does not exceed two thousand years. It is truly unique in its composition and is resistant to autoimmune and allergic diseases.

These people have a mixed diet; There are quite a few dietary restrictions. However, it is recommended to eat as much natural biofood as possible.

Does Rh factor affect nutrition?

We know from school that there are four blood groups in total, and their number doubles when the Rh factor is taken into account. It received this name because it was first discovered after research on rhesus monkeys. The Rh factor can be positive and displayed as (Rh+) or negative (Rh-). It indicates the presence or absence of an antigen (protein) found on the surface of red blood cells (erythrocytes).

But in fact, the division of blood into only four groups is arbitrary - if we take into account all the properties of blood, then there will be much more. D'Adamo ignores this fact.

In D'Adamo's famous book, the effect of the Rh factor is not mentioned at all. Since more than 80% of the world's population has a positive Rh factor, the diet is designed specifically for these people.

Contraindications to the diet

People with the following diseases are prohibited from dieting on their own without consulting your doctor:

• diabetes;
• chronic digestive problems;
• hematopoietic disorder;
• ARVI.

Also, if any of your illnesses have worsened, it is not recommended to go on any diet until you feel better.

Do not under any circumstances experiment on yourself during pregnancy or breastfeeding, remember that you are responsible not only for your life, but also for your baby.

Comments of those who lost weight

• "It is an ideal way of nutrition for people who have no health problems. But if you are overweight, then all kinds of diseases appear a priori, so the diet stops working. Of course, it is convenient to have a wide range of products, but this method did not suit me - doctor, leave on the table "He banned the eating of all the prescribed products. It turned out that the table was almost 90 percent contrary to doctor's recommendations. "
• "I have no medical education, but I clearly see the big drawbacks; the diet is completely unscientific. One of them is that people in the second group have to rely on a vegetarian diet, and those with the third and fourth groups are omnivores, but they are exactly the descendants of the second. In general, I will not even try.
• "I lost 10 kilos in a few months! The blood type diet is very cool, it is very easy to lose weight. I think you can continue this diet for life. I recommend this wonderful diet to everyone who wants to lose weight! "
• "Blood type diet is complete nonsense. Do not torment yourself with these healthy, harmful and neutral products. Eat everything in moderation, without fanaticism. If you want sweet, eat 1-2 candies, not a bar of chocolate; if you want bread, cut a piece and eat it, but do not starve yourself "
• "At work, I showed products approved for the second blood group - the whole team laughed, wiped away tears and ate meat cutlets (yes, yes, half of our team are "farmers"). Honestly, I have never seen a more stupid and completely unacceptable diet than this!

Opinions and criticisms of doctors

Blood test diet is not approved by doctors. After all, each person is so individual that it is necessary to conduct complex research and have data on more than sixty specific genes responsible for endocrine and enzymatic activity, and only then create a diet. And the blood group in this case is a very generalizing factor and cannot be responsible for the correctness of the menu of a particular person.

Therefore, doctors clearly believe that D'Adamo's theory has no scientific basis, has been little studied, but does not cause any harm. In some cases, it even helps stimulate the body and stimulate a faster metabolism.

Also, D'Adamo included truly harmful products among the prohibited foods for all blood groups - sausages and smoked meats, store-bought sauces, ice cream, carbonated drinks, alcohol and others.

And don't forget the placebo effect; the person believes and loses weight.

Pros and cons of the diet

Advantages:

• an extensive list of permitted products;
• easy to carry;
• the ability to create a diverse and balanced menu;
• You can stick with it for a long time.

Flaws:

• there is no clear plan on how, when and in what quantity to consume certain products;
• the diet has no scientific basis, all conclusions are very general;
• Another profitable business for nutritionists and, of course, the creator himself.

Solution

As practice shows, some people really managed to lose weight with this diet. However, they state that the results are not permanent and the weight always returns. So you will have to eat right almost your whole life.
