The 3 principles of the blood group diet

Blood can reveal a lot about a person, as it is essentially the carrier of life and destiny. Did you know that there is even a diet based on blood type, which was very fashionable at one time? Some fat people are still interested in it and study the list of approved products.

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

The history of diet

Once upon a time, people believed that everyone had the same blood. Do you remember the tale of 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 wounded, a theory appeared that the blood was actually different.

Many scientific studies and experiments were conducted with animals and humans, but it was not until 1900 that three blood groups were discovered by Karl Landsteiner, and a little later the fourth by his students.

Currently, the world has adopted an alphanumeric classification:

• O or I – 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. It is carried by 80% of all humanity. The third occurs less often, it is present in 15%, and the fourth is considered the rarest and is represented by only 5%.

At the end of the twentieth century, American naturopath Peter D'Adamo proposed that if some human diseases are directly related to genetic characteristics and often depend on blood type, it is likely that blood type nutrition is possible. He asked each of his patients about their preferences for certain foods and put together a suitable diet for each group. All products were divided into useful, undesirable and neutral.

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

What is he?

Principles and rules

Nutrition according to blood groups is as follows.

• At each stage of human evolution there was a certain diet, when it changed, the blood mutated and a new group appeared. Therefore, each group has a basic set of products.
• To keep your body in good shape, you need to eat the way your ancestors did with a certain blood type. Thanks to the biochemical relationship between blood and food, the "right" foods are better absorbed, digested faster, increase metabolism and strengthen the immune system.
• By eliminating "bad" foods from your diet, you can improve your body's performance, improve your health, and extend your life.

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

If a far northerner who has eaten fatty protein foods all his life decides to move to Europe with its high carb cuisine, the risk of diabetes and digestive problems is high.

You don't have to look far for examples, just look around. Some people hate milk, others prefer plant-based foods, and others simply starve if they don't eat a large piece of meat. Maybe not without reason?

Common dining table for all groups

Let's get acquainted with the research of Dr. D'Adamo, who divided foods according to blood type, highlighting forbidden, permitted and neutral.

Legend:

• products that must be restricted are marked with a "-" sign;
• allowed - "+";
• neutral - "0".

Diet 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 group is absolutely suitable for everyone. By the way, mosquitoes prefer the first blood type more than all the others.

Characteristics of eating behavior (hunter, carnivore)

Absolutely all ancient people who lived in a primitive social system had the first blood type, and the rest happened 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 the few edible fruits and berries that grew wild in the forests.

Thus, the owners of the first group carry the genes of the most ancient hunters and their bodies require as much protein as possible at the genetic level. Unfortunately, the diet is the poorest. If you decide on such a diet, you will have to give up a lot 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.

Diet according to blood type 2

No less common group. It's literally a few hundred years younger than the first one, and evolved through mutation after ancient hunters decided to settle down and do agricultural work.

People with type O blood produce more of the hormone cortisol, which helps them cope with stress. In addition, unfortunately, they are prone to alcoholism.

Characteristics of eating behavior (farmer)

25, 000 years ago, carnivorous hunters learned to cultivate the land and receive its gifts. This is the very beginning of the development of the agricultural lifestyle. People began to build settlements, cultivate fields, and plant cereals and vegetables.

There was less protein food, animals moved away from people, and it became more difficult to get meat.

Sometimes the second blood type is called "vegetarian". Most speakers live in Europe.

The diet of people with the second blood type should include vegetarian food, fish, poultry and dairy products. But it is advisable to give up coffee, beans and meat.

Diet according to blood type 3

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

Peculiarities of eating behavior (nomadic)

As soon as milk and milk products were actively introduced into the diet, and this happened about 10, 000 years ago, the blood again mutated.

Most people with the third blood group live in Asia - they are hereditary nomads.

People of this type are the luckiest - there are practically no restrictions, they are omnivores. Semi-finished products, smoked meats and alcohol should be excluded.

Diet according to blood type 4

The fourth group was formed by the mixing of the second and third groups after people began to live in large settlements and cities.

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

Characteristics of eating behavior (enigma)

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

These people have a mixed type of diet; there are quite a few dietary restrictions. But it is recommended that they consume as much natural organic food as possible.

Does the 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 was first discovered after research on rhesus monkeys, hence its name. The Rh factor can be positive and marked (Rh+) or negative (Rh-). It indicates the presence or absence of an antigen (protein) on the surface of red blood cells (erythrocytes).

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

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

Contraindications to the diet

Without prior consultation with a doctor, it is forbidden for people suffering from the following diseases to follow an independent diet:

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

Also, if any illness has worsened, it is not recommended to go on any diet until you feel better.

Under no circumstances should you experiment on yourself during pregnancy or breastfeeding, remember that you are not only responsible for your life, but also for your baby.

Reviews of weight loss

• "This is an ideal diet for people without health problems. But if you are overweight, you already have all kinds of diseases, so the diet stops. Of course, it is convenient that there is a wide selection of products, but this method did not work for me - the doctor forbade the consumption of all the products allowed in the table. It turned out that the chart was almost 90% against the doctor's recommendation. "
• "I don't have a medical degree, but I can clearly see the huge downsides – the diet is completely unscientific. One is that those in the second group must rely on vegetarian food, and those in the third and fourth groups are omnivores, but they are precisely from the second. I usually don't even try. "
• "I lost 10 kg in a few months! The blood type diet is very cool, it's easy to lose weight. I think you can stay on this diet for the rest of your life. I recommend this amazing diet to everyone who wants to lose weight! "
• "The blood type diet is complete nonsense. Do not torture yourself with these healthy, harmful and neutral products. Eat everything in moderation, without fanaticism. If you want something sweet, eat 1-2 candies, not a whole bar of chocolate; if you want bread, cut off a piece and eat it, but do not starve yourself. "
• "At work, I showed the products approved for the second blood type - the whole team laughed, wiped tears, ate slices of meat (yes, yes, half of our team is "farmers"). Honestly, I have never seen a more stupid and completely unacceptable diet! "

Doctors' opinions and criticism

The blood test diet was not approved by doctors. After all, each person is so individual that it is necessary to conduct complex research and have 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 too generalizing factor and cannot be responsible for the correctness of a particular person's menu.

Thus, doctors clearly believe that D'Adamo's theory has no scientific basis, has been little studied, but does not cause any particular harm. And in some cases, it even helps stimulate the body and activates an accelerated metabolism.

In addition, D'Adamo listed the truly harmful products as prohibited foods for all blood types - sausages and smoked meats, store-bought sauces, ice cream, carbonated drinks, alcohol, and a few more.

Well, don't forget the placebo effect - you believe it and you lose weight.

Advantages and disadvantages of the diet

Advantages:

• a huge list of approved products;
• easy to carry;
• the ability to create a varied and balanced menu;
• you can stick to it for a long time.

Mistakes:

• no clear plan on how, when and in what quantities to consume certain products;
• the diet has no scientific basis, all conclusions are too general;
• another profitable venture for nutritionists and, of course, the creator himself.

Conclusion

As practice shows, some people were actually able to lose weight with this diet. But they note that the results are not permanent - the weight always returns. So, you need to eat properly for almost your entire life.
