3 basic principles of the blood type diet

Blood can tell a lot about a person, because in essence blood is a carrier of life and destiny. Did you know that there is a diet based on blood type that used to be very popular? Some obese people are still interested 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 warning has been warned, so let's try to find out everything about this diet.

History of diet

Long ago, people believed that everyone had the same blood. Remember the fairy tale about Mowgli? "You and I have the same blood – you and me! " But soon, after trying to share their blood with sick and injured people, the theory emerged that the blood was actually different.

Many scientific studies and experiments with animals and humans were carried out, but it was not until 1900 that three blood groups were discovered by Karl Landsteiner, and soon a fourth blood group was discovered by his students.

Currently, the world has adopted alphanumeric classification:

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

The most common blood types 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%.

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 nutrition according to blood type is also possible. He asked each of his patients for specific food preferences and worked out the correct diet for each group. All products are divided into useful, 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 of "4 blood groups - 4 paths to health" spread throughout the world, and everyone who wanted to lose weight immediately tried the new diet.

Who's he?

Basic principles and rules

Nutrition according to blood type is as follows.

• In each period of human evolution, there was a certain diet, when it changed, the blood mutated and new groups appeared. And, therefore, for each group there is a basic set of products.
• To keep your body in shape, you need to eat as your ancestors with a certain blood type did. Thanks to the biochemical relationship between blood and food, the "right" food is absorbed better, digested faster, improves metabolism and strengthens the immune system.
• If you exclude the "wrong" foods from your diet, you can improve the body's performance, improve health and prolong life.

An example is a move 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 protein foods all his life, decides to move to Europe with its cuisine rich in carbohydrates, then there is a high risk of developing diabetes and digestive problems.

You don't even need to go far for examples, look around. Some people hate dairy, others prefer plant-based foods, and still others will starve if they don't eat large amounts of meat. Maybe this is not without reason?

General food table for all groups

Let's get acquainted with Dr. D'Adamo divides foods according to blood type, highlighting those that are prohibited, permitted 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. Most often found among East Slavs and American Indians.

People with the first blood group are universal donors, meaning that this blood type is suitable for everyone. By the way, mosquitoes prefer the first blood group more than any other blood group.

Characteristics of feeding behavior (hunter, meat eater)

Absolutely all ancient people living in a primitive communal system had the first blood group, and 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 includes meat, meat, and more meat, and only then roots, herbs, and a few fruits and berries that grow wild in the forest.

So, the owners of the first group carry the genes of the most ancient hunters and their bodies at the gene level need as much protein as possible. Unfortunately, his diet was the poorest. If you decide on such a diet, you will have to give up many of your favorite foods.

First blood group foods include meat, fish and vegetables. It is best not to consume milk and its derivatives at all.

Diet according to blood type 2

No less common group. It is literally several hundred years younger than the first and was formed through mutation after 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 deal with stress. Additionally, they are unfortunately prone to alcoholism.

Characteristics of eating behavior (farmers)

25, 000 years ago, meat-eating hunters learned to work the land and received its rewards. This was the beginning of the development of the agricultural way of life. People began to build settlements, cultivate fields, grow grain and vegetable crops.

There was less protein in food, animals moved away from humans, and obtaining meat became more difficult.

Sometimes the second blood group is called "vegetarian". The largest number of 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 recommended to stop consuming coffee, nuts and meat.

Diet according to blood type 3

The third group is quite rare and more typical of Asian peoples - they were famous in the past for their large herds of livestock - horses, cows, goats and sheep. Of course, they have to wander from one place to another to feed the animals.

Peculiarities of eating behavior (nomadic)

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

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

This type of people are the luckiest - they have practically no boundaries, they are omnivores. It is important 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 started living in large settlements and cities.

People with blood group IV are more likely to suffer from dementia and Alzheimer's disease. But they are also universal plasma donors, which are invaluable in the treatment of burns.

Peculiarities of eating behavior (enigma)

This blood is the youngest, its age does not exceed two thousand years. Its composition is truly unique and resistant to autoimmune diseases and allergies.

These people have a mixed type of diet, there are few dietary restrictions. However, it is recommended for them to consume as much natural bio-food as possible.

Does the Rh factor affect nutrition?

From school we know that there are four blood groups, and if we take 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 named (Rh+) or negative (Rh-). This shows whether there are antigens (proteins) 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. D'Adamo ignores this fact.

In D'Adamo's famous book there is no mention at all about the influence of the Rh factor. Since more than 80% of the world's population has a positive Rh factor, this diet is designed specifically for these people.

Contraindications to diet

Without first consulting a doctor, sufferers of the following diseases are prohibited from dieting on their own:

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

In addition, if there is a disease that is getting worse, 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 your baby.

Reviews of those who lose weight

• "This is an ideal diet for people who do not have health problems. But, if you are overweight, then a priori there are various kinds of diseases, so the diet stops working. Of course it is convenient because there is a large choice of products, but this method is not suitablefor me - the doctor forbade all the products allowed on the table to be eaten. It turned out that the table was almost 90% contrary to the doctor's recommendations. "
• "I have no medical education, but I clearly see the huge disadvantages - this diet is completely unscientific. One of them is that people from the second group have to rely on vegetarian food, and those in the third and fourth groups areomnivores, but they are precisely the descendants of the second group. In general, I wouldn't even try. "
• "In a few months I lost 10 kg! The blood type diet is really cool, it's easy to lose weight. I think you can stay on this diet for the rest of your life. I recommend this amazing 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 sweets, not a whole chocolate bar; if you want bread, cut off a piece and eat it, but don't starve yourself. "
• "I showed products approved for the second blood group at work - the whole team laughed, wiped away tears and ate pieces of meat (yes, half of our team were "farmers"). Honestly, I have never seen a more stupid diet andcompletely unacceptable! "

Doctors' opinions and criticism

The blood test diet is 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 responsible for endocrine and enzymatic activity, and only then make a diet. And blood type in this case is a factor that is too generalizing and cannot be responsible for the correctness of a particular person's menu.

Therefore, doctors clearly believe that D'Adamo's theory has no scientific basis, is little studied, but does not cause any particular harm. And in some cases, it even helps stimulate the body and enable a faster metabolism.

In addition, D'Adamo includes truly dangerous products in the prohibited diet for all blood types - sausages and smoked meats, store sauces, ice cream, carbonated drinks, alcohol and some others.

Well, don't forget the placebo effect – a person becomes a believer and loses weight.

Pros and cons of diets

Profit:

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

Lack:

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

Conclusion

As practice shows, some people are really able to lose weight on this diet. But they note that the results do not last long - the weight always comes back. So you have to eat right most of your life.
