3 basic principles of the blood group diet

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

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

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, the theory arose that the blood was actually different.

Many scientific studies and experiments were conducted with animals and humans, but it was only in 1900 that three blood groups were discovered by Carl Landsteiner, 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 are 80% of all humanity. The third is less common, 15% have it, and the fourth is the rarest and is represented by only 5%.

American naturopath Dr. Peter D'Adamo proposed at the end of the twentieth century that if some human diseases are directly related to genetic characteristics and often depend on blood type, then it is likely that nutrition based on blood type is also possible. He asked each of his patients about certain food preferences and devised the right diet for each group. All products are divided into useful, undesirable and neutral.

D'Adamo has written several books on diet. They achieved great success among American readers and became bestsellers. Then his concept "4 blood groups - 4 ways to health" spread all over the world, and everyone who wanted to lose weight was in a hurry to try the new diet.

what is it

Basic principles and rules

Nutrition according to blood groups is as follows.

• 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 great shape, you need to eat the way your ancestors did with a certain blood type. Thanks to the biochemical connection between blood and food, "correct" food is absorbed better, absorbed faster, increases metabolism and strengthens the immune system.
• If you eliminate the "wrong" foods from your diet, you can improve the functioning of the body, promote health and prolong 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 native of the far north, who has been eating high-fat protein food all his life, decides to move to Europe with high-carbohydrate cuisine, then the risk of diabetes and digestive problems is high.

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

General food table for all groups

Let's get acquainted with the study of Dr. D'Adamo, who divided food according to blood group, distinguishing prohibited, permitted and neutral.

Legend:

• Products that should be restricted are marked with a "-" sign;
• Allowed – "+";
• Neutral - "0".

Diet 1 according to blood group

The most common in the world is the first positive blood group. Most often it is 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 group more.

Peculiarities of feeding behavior (hunter, carnivore)

All ancient people living in a primitive communal system had the first blood group, and the rest happened through mutation.

Now recall 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 basic 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 ancient hunters, and their body at the gene level requires as much protein as possible. Diet, unfortunately, is the poorest. If you decide on such a diet, then you will have to give up a large number of your favorite foods.

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

Diet according to blood type 2

A less common group. It is actually several hundreds of years younger than the first one and was formed by mutation after the ancient hunters decided to settle in a permanent place and take up agricultural work.

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

Peculiarities of feeding behavior (farmer)

25, 000 years ago, carnivorous hunter-gatherers 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 grain crops and vegetables.

There was less protein food, animals became separated from humans and it became more difficult to obtain 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 according to the 3rd blood group

The third group is quite rare and more characteristic of Asian peoples - they were 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 feeding 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 continued to mutate.

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

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

Diet according to the 4th blood group

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 type IV blood are more likely to develop 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 resistant to autoimmune and allergic diseases.

These people have a mixed diet, with very few dietary restrictions. But it is desirable for them to eat 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 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 designated (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 they will be much more. D'Adamo ignores this fact.

D'Adamo's famous book does not mention the influence 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.

Diet contraindications

Without prior consultation with a doctor, people with the following diseases are prohibited from following the diet independently:

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

In addition, if any disease has worsened, it is also not recommended to follow any diet until you feel better.

Do not experiment on yourself during pregnancy and breastfeeding; Remember that you are responsible not only for your life, but also for the child.

Reviews about weight loss

• "This is an ideal diet for those who do not have health problems. But if you are overweight, then a priori there are all kinds of diseases, so the diet stops working. It is convenient, of course, that there is a wide selection of products, but I did not like this method - the doctor forbade me to eat all the products allowed on the table. It turns out that the table contradicts the doctor's recommendations by almost 90%. "
• "I don't have a medical education, but I clearly see huge flaws - the diet is completely unscientific. One of them is that people with the second group must rely on vegetarian food, and those with the third and fourth are omnivores, but they are exactly the descendants of the second. In general, I'm not even wrong.
• "I lost 10 kg in a few months! Blood type diet is very cool, easy to lose weight. I think you can stay on this diet for life. I recommend this great diet to anyone who wants to lose weight! "
• "The blood type diet is complete nonsense. Do not suffer with these healthy, harmful and neutral products. Eat everything in moderation, without fanaticism. If you want something sweet, eat 1-2 candies, not the whole chocolate, if you want bread, cut a piece and eat it, but don't starve yourself.
• "At work, I showed the products approved for the second blood group - the whole team laughed, wiped their tears and ate meat cutlets (yes, yes, half of our team is a "farmer"). To be honest, I have never seen such a stupid and completely unacceptable diet! "

Opinions and criticism of doctors

Doctors did not approve the blood test diet. After all, each person is so individual that it is necessary to conduct a complex study and have data on more than sixty specific genes responsible for endocrine and enzyme 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.

Thus, doctors clearly believe that D'Adamo's theory has no scientific basis, is little studied, but does not cause any special harm. In some cases, it helps to stimulate the body and accelerate the activation of metabolism.

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

Do not forget about the placebo effect - people believe and lose weight.

The pros and cons of the diet

Advantages:

• A huge list of allowed products;
• easy to carry;
• the possibility of creating a varied and balanced menu;
• You can hold it for a long time.

Flaws:

• There is no clear plan on how, when and in what quantities certain products should be consumed;
• The diet has no scientific basis, all conclusions are very 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 result does not last - the weight returns unchanged. So you will have to eat right almost all your life.
