3 basic principles of the blood type diet

Blood can tell 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 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 me! "But soon, after trying to share their blood with the sick and wounded, a theory emerged that the blood was actually different.

Many scientific studies and experiments with animals and people were carried out, but only in 1900 were three blood groups 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 I – first;
• A (II) – second;
• B (III) – third;
• AB (IV) – fourth.

The most common blood groups on the globe 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%.

American naturopathic doctor Peter D'Adamo suggested 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 according to blood type is also possible. He inquired about preferences for certain foods from each of his patients 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 types - 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 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, the "right" foods are better absorbed, digested faster, increase metabolism and strengthen the immune system.
• If you exclude "wrong" 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 local unusual cuisine is not accepted by the body and health problems begin.

If a resident of the Far North, who has been eating 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 for examples, look around. Some people hate milk, others prefer plant foods, and others will simply go hungry if they don’t eat a large piece of meat. Perhaps this is not without reason?

General food table for all groups

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

Legend:

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

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

Features of eating behavior (hunter, meat eater)

Absolutely all ancient people living in a primitive communal system had the first blood group, and all the rest occurred 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.

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

The diet for 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 is literally a couple of hundred years younger than the first and was formed through mutation after the ancient hunters decided to settle in a permanent place and engage in agricultural work.

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

Features of eating behavior (farmer)

25, 000 years ago, meat-eating 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 crops 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". 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 blood type 3

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

Peculiarities of eating behavior (nomad)

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 - these 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 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 have a mixed type of diet; there are quite few dietary restrictions. But it is advisable for them to eat as much natural bio-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, which is why it got 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) that is 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 there will be much 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 your doctor, it is prohibited for people with the following diseases to follow a diet on their own:

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

In addition, if any illnesses have worsened, it is also not recommended to go on 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 losing weight

• "This is an ideal diet for people who have no health problems. But, if you are overweight, then a priori there are all sorts of diseases, so 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 forbade all the products allowed in the table to be eaten. It turns out that the table is almost 90% contrary to the doctor’s recommendations. "
• "I don’t have a medical education, but I clearly see the huge disadvantages - the diet is completely unscientific. One of them is that people with the second group should rely on vegetarian food, and those who have the third and fourth are omnivores, but they are precisely descended from the second. In general, I won’t even try. "
• "In a few months I lost 10 kg! 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 wonderful 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 don’t starve yourself. "
• "I showed the approved products for the second blood group at work - 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! "

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 data on more than sixty specific genes that are responsible for endocrine and enzymatic activity, and only then create a diet. And the blood type in this case is too generalizing a 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, 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 truly harmful products among the prohibited foods for all blood groups - sausages and smoked meats, store-bought sauces, ice cream, carbonated drinks, alcohol and some others.

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

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 to it for a long time.

Flaws:

• 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, the creator himself.

Conclusion

As practice shows, some people were actually able to lose weight on this diet. But they note that the results do not last - the weight invariably returns. So you will have to eat right almost all your life.
