3 basic principles of diet by blood type

Blood can say a lot about a person, because it is essentially the bearer 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 big guys are still interested and are studying the list of authorized products.

It must be said from the outset that this technique has been repeatedly criticized by doctors and has no scientific basis. But forewarned is better forearmed, so let’s try to find out everything about this diet.

History of the regime

In the past, 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 attempted to share their blood with the sick and wounded, a theory emerged that the blood was actually different.

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

Currently, the world has adopted an alphanumeric classification:

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

The most common blood groups on the planet are the first and second blood groups. Its carriers represent 80% of all humanity. The third is less common, 15% are affected, and the fourth is considered the rarest and is represented by only 5%.

The American naturopathic doctor Peter D'Adamo suggested at the end of the 20th century that if certain human diseases are directly linked to genetic characteristics and often depend on blood type, then it is likely that a diet according to blood type is also possible. He learned about each of his patients' preferences for certain foods and compiled the appropriate diet for each group. All products have been divided into useful, undesirable and neutral.

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

What is she?

Basic principles and rules

Nutrition according to blood groups comes down to the following.

• In each period of human evolution there was a certain diet, when it changed, the blood mutated and a new group appeared. And therefore, for each group there is a basic set of products.
• To keep your body in tip-top shape, you need to eat like your ancestors did with a certain blood type. Thanks to the biochemical connection between blood and food, "good" foods are better absorbed, digested faster, increase metabolism and strengthen the immune system.
• If you exclude "bad" foods from your diet, you can improve the body's performance, promote health and prolong life.

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

If a resident of the Far North, who has consumed fatty and protein foods all his life, decides to settle in Europe with its cuisine rich in carbohydrates, then the risk of diabetes and digestive problems is high.

You don’t even have to go far to find examples, just look around you. Some people hate milk, others prefer plant foods, and still others will simply be hungry if they don't eat a large piece of meat. Maybe it’s not without reason?

General catering table for all groups

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

Diet according to blood group 1

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

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

Characteristics of feeding behavior (hunter, meat eater)

Absolutely all ancient people living in a primitive community system had the first blood group, and everything else was the result of mutations.

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 then only roots, herbs and a few edible fruits and berries that grew wild in the forests.

So, the owners of the first group carry the genes of the most ancient hunters and their body at the genetic level needs as much protein as possible. Unfortunately, the diet is the poorest. If you opt for such a diet, then you will have to give up many 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 group 2

No less common group. It is literally a few hundred years younger than the first and was formed by mutation after ancient hunters decided to settle in a permanent place and take up agricultural work.

People with blood type O produce more cortisol, a hormone that helps cope with stress. Additionally, they are unfortunately prone to alcoholism.

Characteristics of feeding 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 way of life. People began to build settlements, cultivate fields, plant grain and vegetables.

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

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. But it is advisable to give up coffee, beans and meat.

Diet according to blood group 3

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

Peculiarities of eating behavior (nomadic)

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

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

This type of people is the luckiest - they have practically no restrictions, they are omnivores. It is necessary to exclude semi-finished products, smoked meats and alcohol.

Diet according to blood group 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 group IV are more likely to suffer from senile dementia and Alzheimer's disease. But they are also universal donors of plasma, very valuable in the treatment of burns.

Peculiarities of eating behavior (enigma)

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

These people have a mixed diet; there are relatively few dietary restrictions. But they are advised to eat as many natural biofoods as possible.

Does the Rh factor affect nutrition?

From school we know that there are four blood groups in total, and taking into account the Rh factor, their number doubles. It was first discovered after research on rhesus monkeys, hence its name. The Rh factor can be positive and is designated (Rh+) or negative (Rh-). It indicates the presence or absence of an antigen (protein) present 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, there will be many more of them. D'Adamo ignores this fact.

In D'Adamo's famous book, there is no mention of the influence of the Rh factor. 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

Without prior advice from your doctor, people with the following diseases are prohibited from following a diet themselves:

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

Additionally, if any illnesses have worsened, it is also not recommended to follow a 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 the baby.

Reviews of those who lose weight

• "It is an ideal diet for people who have no health problems. But if you are overweight, there are a priori all kinds of diseases, so the diet stops working. It is of course convenient that there is a wide selection of products, but this method did not suit me - the doctor forbade eating all the products allowed in the table. It turns out that the picture is almost 90% contrary to the doctor's recommendations.
• "I don't have a medical background, but I clearly see the huge downsides - the diet is completely unscientific. One of them is that people from the second group should rely on vegetarian food, and those from the third and fourth are omnivores, but they are descended precisely from the second. Usually I won't even try.
• "In a few months I lost 10 kg! The blood group diet is very cool, it is easy to lose weight. I think you can follow this diet for the rest of your life. I recommend this wonderful diet to anyone who wants to lose weight! »
• "The blood type diet is complete nonsense. Don't 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 chocolate bar; if you want bread, cut a piece and eat it, but don't starve yourself. »
• "I showed at work the products approved for the second blood group - the whole team laughed, wiping away tears and eating a meat cutlet (yes, yes, half of our team are "farmers"). Honestly, I have never seen a more stupid and completely unacceptable diet!

Opinions and reviews of doctors

The diet based on blood tests has not been 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 then create a diet. And the blood group in this case is too generalizing a factor and cannot be responsible for the correctness of the menu of a particular person.

So, 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 activate a more accelerated metabolism.

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

Well, don't forget the placebo effect: a person gains and loses weight.

Advantages and disadvantages of the diet

Benefits :

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

Defaults:

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

Conclusion

As practice shows, some people managed to lose weight thanks to this diet. But they note that the results don't last - the weight invariably returns. So you will have to eat well most of your life.
