3 basic principles of the blood type diet

Blood can tell a lot about a person, because it is basically the carrier 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 approved products.

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

The history of 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 trying to share their blood with the sick and wounded, a theory emerged that the blood was really different.

Many scientific studies and experiments were done with animals and people, but Karl Landsteiner only discovered three blood groups in 1900, and a little later his students discovered the fourth.

Currently, the world has adopted an alphanumeric classification:

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

The most common blood groups in the world are the first and second blood groups. Its carriers are 80% of all mankind. The third is less common, at 15%, and the fourth is considered the rarest at only 5%.

The 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 the blood type, then it is likely that nutrition according to the blood type could also be possible. He asked about certain food preferences from each of his patients and put together the right diet for each group. All products were divided into useful, undesirable and neutral.

D'Adamo has written several books on diet. They were extremely successful among American readers and became bestsellers. Then his concept of "4 types of blood - 4 paths to health" spread around 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 the appearance of a new group. And, therefore, for each group there is a basic set of products.
• To keep your body in great shape, you need to eat like 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 body does not accept the unusual local cuisine 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 rich carbohydrate cuisine, then there is a high risk of diabetes and digestive problems.

You don't even have to go far for examples, just look around. Some people hate milk, others prefer plant foods, and others will starve if they don't eat a large piece of meat. Maybe this is not without reason?

General food table for each group

We will get to know the research of Dr. D'Adamo, who divided foods according to blood type, emphasizing prohibited, permitted and neutral.

Legend:

• the products that should be limited are marked with a "-" sign;
• approved - "+";
• neutral – "0".

diet according to blood type 1

The most common in the world is the first positive blood group. It is often found among 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.

Aspects of eating behavior (hunter, meat eater)

Absolutely every ancient person living in a primitive community system had the first blood group, and all the rest happened by mutation.

Now remember the history of the Old World, archaeological excavations and the conclusions of scientists - 40, 000 years ago, primitive people lived hunting and gathering. Their main diet consisted of meat, meat and more meat, with only roots, herbs and the few edible fruits and berries that grew wild in the forests.

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

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

diet according to blood type 2

A no less popular group. It is literally a few hundred years younger than the first one and was established 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 of the hormone cortisol, which helps to cope with stress. In addition, they are, unfortunately, prone to alcoholism.

Aspects of eating behavior (farmer)

25, 000 years ago, hunters who eat meat learned how to cultivate the land and receive its gifts. This is the very beginning of the development of the agricultural way of life. People started building settlements, cultivating fields, planting grain and vegetable crops.

Protein food was less, animals moved away from people, and meat became harder to find.

The second blood group is sometimes 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 the peoples of Asia - they were famous in the old days for their huge herds of livestock - horses, cows, goats and sheep. Of course, they had to wander from place to place to feed the animals.

Characteristics 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 are lucky - they have almost 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 mixing the second and third groups after people began to live in settlements and large cities.

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

Characteristics 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 diet; there are few dietary restrictions. But it is advisable for them to eat as much natural organic food as possible.

Does Rh factor affect nutrition?

From school we know that there are four blood groups in total, and taking the Rh factor into account, their number is doubled. It was first discovered after research on rhesus monkeys, hence its name. The Rh factor can be positive and named (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 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 specifically designed for these people.

Contraindications to the diet

Without prior consultation with your doctor, 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 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 not only responsible for your life, but also for the child.

Reviews of those who lose weight

• "This is a great diet for people who have no 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 an optionthere is a wide range of products, but this method was not suitable for me - the doctor forbade eating all the products allowed in the table. It seems 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 with the third are omnivoresand the fourth of them, but they are precisely descended from the second. In general, I will not even try. "
• "In a few months I lost 10 kg! The blood type diet is very cool, it is easy to lose weight. I think you can stay on this diet for the rest of your life. I recommendthis great diet for 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 barchocolate; if you want bread, cut off a piece and eat it, but don't be hungry. "
• "I showed the approved products for the second blood group at work - the whole team laughed, wiped tears and ate meat cutlet (yes, yes, half of our team are "farmers"). Honestly, I didn't see an essaymore stupid and completely unacceptable food! "

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 carry out complex research and have data on more than sixty specific genes responsible for endocrine and enzymatic activity, and only then to create a diet. And the blood type in this case is too general a factor and cannot be responsible for the accuracy of a particular person's menu.

Therefore, doctors clearly believe that D'Adamo's theory, which has not been studied much, has no scientific basis, but it is not particularly harmful. And in some cases, it even helps to stimulate the body and activate a faster metabolism.

In addition, D'Adamo included very harmful products among the forbidden foods for each blood group - 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.

Advantages and disadvantages of the diet

Advantages:

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

Defects:

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

Conclusion

As practice shows, some people were able to lose weight on this diet. But they note that the results don't last - the weight always comes back. So you will have to eat right almost all your life.
