3 basic principles of the blood type diet

Blood can say a lot about a person, because it is essentially a carrier of life and destiny. Did you know that there is also the blood type diet, which was once very fashionable? Some fatties are still interested in it and study the list of permitted products.

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

History of the diet

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

Many scientific studies and experiments were conducted with animals and people, but only in 1900 did Karl Landsteiner discover three blood groups, and a little later the fourth was discovered 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. Its carriers represent 80% of all humanity. The third is less common, 15% have it, while 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 some human diseases are directly related to genetic characteristics and often depend on blood type, then it is likely that blood type nutrition is also possible. He asked each of his patients about preferences for certain foods and compiled the correct 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 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?

Fundamental principles and rules

Nutrition by blood groups boils down to the following.

• In each period of human evolution there was a certain diet, when it changed, the blood changed 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 with a certain blood type did. Thanks to the biochemical connection between blood and food, the "right" foods are absorbed better, digested faster, increase metabolism and strengthen the immune system.
• If you exclude the "wrong" foods from your diet, you can improve the body's performance, promote health and prolong life.

An example is relocation to another habitat or 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 eaten 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 need to go far to find examples, just look around. Some people hate milk, some prefer plant foods, and some will simply starve if they don't eat a large piece of meat. Maybe this is not without reason?

General food table for all groups

We know the research of Dr. D'Adamo, who divided foods based on blood type, highlighting prohibited, permitted and neutral.

Legend:

• products that should be limited are indicated with a "-" sign;
• allowed – "+";
• neutral – "0".

Diet based on blood type 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 more than all others.

Characteristics of eating behavior (hunter, meat eater)

Absolutely all ancient people living in a primitive community system had the first blood group, and everything else 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 included meat, meat and more meat, and only then roots, herbs and those few edible fruits and berries that grew wild in the forests.

Therefore, the owners of the first group carry the genes of the most ancient hunters, and their body at the genetic level requires as much protein as possible. The diet, unfortunately, is the poorest. If you decide to follow such a diet, you will have to give up a huge number of your favorite foods.

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

Diet based on blood type 2

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

People with blood type O produce more cortisol, a hormone that helps you cope with stress. Also, 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 beginning of the development of the agricultural lifestyle. People began to build settlements, cultivate fields, 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 group is called "vegetarian". The largest number 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 based on blood type 3

The third group is quite rare and is more characteristic of Asian peoples: in the old days they were famous for their huge herds of livestock: horses, cows, goats and sheep. Naturally they had to wander 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 changed 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 based on blood type 4

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

People with blood type IV are more likely to have senile dementia and Alzheimer's disease. But they are also universal donors of plasma, which is 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 is resistant to autoimmune and allergic diseases.

These people follow a type of mixed diet; there are few dietary restrictions. But it is advisable that they eat as much natural organic food 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 the name. The Rh factor can be positive and is indicated (Rh+) or negative (Rh-). 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, there will be many more of them. D'Adamo ignores this fact.

In D'Adamo's famous book there is no mention at all 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 consultation with a doctor, people suffering from the following diseases are prohibited from following a diet alone:

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

Also, if any disease has worsened, it is not advisable to follow any diet until you feel better.

Do not experiment on yourself under any circumstances 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

• "This is an ideal diet for people who have no health problems. But if you are overweight, a priori there are all kinds of diseases, then the diet stops working. It is convenient, of course, that there is a wide selection of products, but this method did not suit me: the doctor prohibited eating all the products allowed in the table. It turns out that the table is almost 90% contrary to the doctor's recommendations. "
• "I have no medical training, but I clearly see the huge disadvantages: the diet is completely unscientific. One of them is that people of the second group should rely on vegetarian food, and those of the third and fourth are omnivores, but descended right from the second. In general, I won't even try.
• "In just a few months I lost 10 kg! The blood type diet is very interesting, it is easy to lose weight. I think you can continue to follow this diet for the rest of your life. I recommend this wonderful diet to everyone 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 sweets, not a whole bar of chocolate; if you want bread, cut a piece and eat it, but don't starve.
• "I showed at work products approved for the second blood group - the whole team laughed, wiping their 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! "

Doctors' opinions and criticisms

The blood test diet 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 only 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.

Doctors are therefore convinced that D'Adamo's theory has no scientific basis, has been little studied, but does not cause particular damage. And in some cases it also helps to stimulate the body and activate a more accelerated metabolism.

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

Well, do not forget about the placebo effect: a 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 varied and balanced menu;
• you can keep it for a long time.

Cracking:

• there is 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 business for nutritionists and, of course, for the creator himself.

Conclusion

As practice shows, some people actually managed to lose weight on this diet. But they note that the results don't last: The weight invariably returns. So you will have to eat well almost your entire life.
