3 main principles of the blood type diet

Blood can tell a lot about a person, as it is essentially a carrier of life and destiny. Did you know there's even a blood type diet that was once all the rage? Some fats are still interested in it and research the list of allowed products.

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

Diet history

Once upon a time, people believed that everyone had the same blood. Remember the tale of Mowgli? "You and I are of the same blood—you and I! "But soon after trying to share his own blood with the sick and injured, the theory emerged that blood actually makes a difference.

A lot of scientific research and experiments were carried out with animals and humans, but it was not until 1900 that the three blood groups were discovered by Karl Landsteiner, and a little later the fourth by his students.

Currently, the alphanumeric classification used in the world is:

• Oh or I am the 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 considered the rarest and is represented by only 5%.

The American naturopathic doctor Peter D'Adamo proposed 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 possible to eat according to blood type. He inquired about the selection of certain foods from each of his patients and developed a suitable diet for each group. All products were divided into beneficial, undesirable and neutral.

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

Who is she?

Basic principles and rules

Nutrition according to blood groups is as follows.

• In each period of human evolution, a certain diet existed, 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 with a certain blood type did. Due to the biochemical connection between blood and food, the "right" food is better absorbed, digested faster, the metabolism is accelerated, and the immune system is strengthened.
• By eliminating the "wrong" foods from your diet, you can improve your body's performance, improve your health, and extend your life.

An example is moving to another place or even tourism, when the body does not accept the local unusual cuisine and health problems begin.

If a resident of the Far North, who has eaten a high-fat protein diet all his life, decides to move to Europe, which is rich in carbohydrates, then there is a high risk of diabetes and digestive problems.

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

Common food table for all groups

Let's get acquainted with the research of Dr. D'Adamo, who divided food according to blood type, highlighting prohibited, permissible and neutral.

Legend:

• products that should 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 suitable for absolutely everyone. By the way, mosquitoes prefer the first blood type more than all others.

Peculiarities of eating behavior (hunter, meat eater)

Absolutely all ancient people who lived in a primitive communal system had the first blood group, and the rest happened by mutation.

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

Thus, the owners of the first group carry the genes of the oldest hunters and their organism requires as much protein as possible at the gene level. Unfortunately, the diet is the poorest. If you decide to follow this diet, you will have to give up many of your favorite foods.

The diet of the first blood type 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 is a couple of hundred years younger than the first one and was formed by mutation when ancient hunters decided to settle in a permanent place and engage in agricultural work.

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

Peculiarities of eating behavior (farmer)

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

Protein food decreased, animals moved away from people, meat became more difficult 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 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 nations - they were famous for their huge herds of animals - horses, cows, goats and sheep in ancient times. Of course, they had to wander from one place to another to feed the animals.

Peculiarities of eating behavior (nomads)

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

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

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

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

Peculiarities of eating behavior (riddle)

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 mixed diet; there are relatively few dietary restrictions. However, it is advisable 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 denoted (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 only 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.

In D'Adamo's famous book, the influence 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.

Diet contraindications

Without consulting a doctor in advance, it is forbidden for people with the following diseases to follow a diet on their own:

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

In addition, if any diseases have flared up, it is also not recommended to follow any diets until you feel better.

During pregnancy or breastfeeding, do not experiment on yourself in any way, 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 those without health problems. But if you are overweight, then a priori there are all kinds of diseases, so the diet stops working. It is convenient, it is clear that there is a large selection of products, but this method did not suit me - the doctor forbade me to eat all the products allowed in the table. It turns out that the table is almost 90% against the doctor's recommendations.
• "I don't have a medical degree, but I can clearly see the huge flaws - the diet is completely unscientific. One of them is that people of the second group should rely on vegetarian food, and those with the third and fourth should be omnivores, but they are the ones who come from the second. In general, I won't even try. "
• "I lost 10 kg in a few months! Blood type diet is very cool, easy to lose weight. I think you can stick to this diet for the rest of your life. I recommend this amazing diet to anyone 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 instead of a whole bar of chocolate; if you want bread, cut off a piece and eat it, but do not starve.
• "At work, I showed the approved products for the second blood type - the whole team laughed, wiped tears and ate a meatball (yes, yes, half of our team are "farmers"). Honestly, I have not seen a more stupid and completely unacceptable diet!

Doctors' opinion and criticism

The blood test diet was not approved by the doctors. After all, each person is so individual that it is necessary to conduct complex studies 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 a particular person's menu.

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 to stimulate the body and activate a more accelerated metabolism.

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

Well, don't forget about the placebo effect - a person believes and loses weight.

The pros and cons of the diet

Advantages:

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

Disadvantages:

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

Conclusion

As practice shows, some people actually managed to lose weight by following this diet. However, they note that the results are not long-lasting - the weight always comes back. So you will have to eat right for most of your life.
