Nutrition system and healthy foods for the first blood group — review of scientific research

Sometimes people who consume the same foods get the opposite result. Someone is losing weight, and someone continues to gain weight. According to American scientists, it's all about genetics.

It turns out that depending on what a person's blood type is (and it is due to our distant history), his dietary preferences, well-being, and the usefulness of the food he eats manifest themselves.

Blood type diet is a relatively young phenomenon that entered people's lives at the very end of the 20th century. Nevertheless, this food system quickly gained wide popularity among many thousands of its followers.

So, what is recommended for people with blood type 1 to eat and are there any studies confirming the effectiveness of such a technique?

What does scientific research say?

Existing scientific studies cannot yet confirm the effectiveness of this nutrition system D&8217;Adamo.

In one major study , 1,455 adults ate according to the recommendations for blood type 1, and this really had a positive effect on their health. But this effect was observed in people with all blood groups, not just the first one.

Probably, the improvement in health was due to the fact that the participants simply started eating healthier food than before. After all, regardless of blood type, the D&8217;Adamo method focuses on natural and healthy foods, as opposed to the so-called &171;Western diet, consisting of refined sugar, fast food and trans fats.

Another large-scale survey study from 2013 also did not confirm the effectiveness of this power supply system.

The essence of the technique

The "bloody" weight correction technique was developed in the 20th century by the American naturopathic physician Peter D&8217;Adamo based on his father's research. He proved that people digest food differently depending on their blood type.

Blood groups, according to this concept, determine the similarity and difference of people, their emotional features , a tendency to certain diseases. Food gives the body different elements, in particular, lecithins, and different blood groups "meet" them in different ways: they conflict or cheerfully greet.

If the lecithin structure and blood type are hostile to each other, food is poorly digested, and disorders occur. Therefore, choosing the right products is the basis Feel good and performance .

The concept of D&8217;Adamo is based on the statement that the emergence of blood types occurred in accordance with the epochs of human development. In each period, certain foods prevailed in the diet of people, and they are favorable for representatives of different groups.

There are foods that make a person with a certain blood type feel great and mentally , and physically. From others, he becomes depressed, feels discomfort and dissatisfaction with life. Products for each blood group were divided into 3 classes:

1. Useful. They heal the body, strengthen the immune system, normalize metabolism, promote weight loss, since all the useful and necessary substances from them are absorbed as much as possible.
2. Harmful, or "heavy". They are hard to digest by a person with a certain blood type, have a toxic effect, contribute to the accumulation of fats and weight gain.
3. Neutral. They do not bring tangible benefits, but they also do not cause harm if consumed in moderation. They help to diversify the diet.

The popularity of the blood type diet is based on its effectiveness, as well as the fact that you do not need to count calories and grams, and severely limit yourself in nutrition. It is not the amount of food that is important, but what exactly was eaten.

The principles of the blood type diet include the following points:

1. Dividing people by type. These are 1, 2, 3, 4 blood groups.
2. Nutrition according to its type. Foods that are useful and allowed for one type of person may be harmful to another.
3. Appropriate physical activity. The individual characteristics of the groups imply different physical activity.
4. Taking dietary supplements. Due to the fact that some dishes fall into the category of prohibited, the body does not receive some elements: minerals, vitamins, etc. Therefore, some vitamins and minerals need to be taken in addition to the diet.

What does the Rh factor affect?

Numerous studies in the field of dietetics prove that the Rh factor has no effect on the digestibility of food. This means that the choice of products, menu and dietary recommendations will be the same for the first positive and first negative blood groups.

Product Table

We suggest you familiarize yourself with the table below.

 

Useful

Group 1 is the most common and at the same time the most ancient. It is believed that it was originally possessed by all people who appeared on Earth. There were no other groups then. The ancient people got their food mainly by hunting, and the owners of group 1 inherited the love of meat food.

A meat diet and limited consumption of cereals and vegetables have a positive effect on representatives of the first group today. Certain foods cleanse the body of toxins that have taken a fancy to fatty tissues, and enrich the body with the necessary substances.

People with group 1 are active and purposeful, prefer intense physical activity. They are the winners. The basis of their nutrition system should be protein. With a balanced diet, these people quickly achieve their goals, but a violation of the balance is fraught with inflammation.

To restore health and lose weight, it is recommended that representatives of the "hunters" include in the diet:

1. Artichokes, kale, spinach and broccoli. They regulate the digestive process and help improve metabolism.
2. Red meat and liver. Eat beef, mutton, veal and lamb meat. They contain a lot of iron, they are rich in vitamin B12 and protein, which normalize metabolism.
3. Seafood and some freshwater fish. Give preference to salmon, mackerel, sturgeon, perch, cod, pike, anchovies, mussels, oysters, shrimps. Love algae. Fish oil can improve blood clotting and help protein absorption.
4. Foods with a high iodine content. The same seaweed and seaweed, iodized salt, greens and green vegetables will make up for the lack of iodine in the hunter's body.
5. Oils. Olive and linseed oil are the most optimal for people of blood type 1. The rest are poorly absorbed.
6. Drinks. Green tea and pineapple, prune, and plum juices are best absorbed. And to calm your nerves, you can drink a decoction of ginger, tea with rosehip, mint or lime.

In addition to this list of products, nuts (especially walnuts, 2-5 nuts daily are enough), figs, prunes are useful for "hunters". They replenish the body with trace elements. And bread baked from sprouted seeds contains very little gluten, which is harmful to people with the "O" group.

Harmful

If we talk about harmful foods in relation to nutrition by blood type, then harm does not mean dangerous here. They are simply undesirable for the first group because of the peculiarities of the structure of the body's cells.

Excess in the diet of these foods can provoke diseases of the thyroid gland:

• ,
• Arthritis;
• Various allergies;
• Tendency to stroke, etc.

Junk food can lead to a slowdown in metabolism, which will provoke weight gain, so these products can easily be blacklisted. It will include:

1. Foods high in gluten (gluten). They are made from cereals such as wheat, rye, barley, and oats. Gluten helps slow down the metabolic processes in the body.
2. Products that reduce the intensity of insulin action. These include corn, beans, beans, and lentils. With a decrease in the intensity of insulin, the metabolic rate also decreases.
3. Vegetables that provoke hypothyroidism : cauliflower, white cabbage and Brussels sprouts. Vegetables of the solanaceae family (potatoes, eggplants). They are dangerous because they lower the function of the thyroid gland.
4. Sour fruits. But pineapple, figs, plums or figs should not be neglected.
5. Dairy products with high fat content. Do not get carried away with butter, cheese, cream, cottage cheese and others. It is better to prefer low-fat fermented milk or soy substitutes to them. Dairy products are characterized by poor digestibility, but they serve as a source of calcium.

However, it is not necessary to completely exclude all these products from the diet. You just need to minimize their consumption.

Neutral

Moderation has always been welcomed in any area of life. Nutrition is no exception. In order for a representative of the 1st blood group to feel comfortable, he needs not only meat and figs, but also other foods rich in vitamins and minerals. They complement and diversify the diet, and if consumed in small quantities, they do not harm the body. Among such foods, hunters should sometimes eat:

1. Seafood : crustaceans, eel, flounder.
2. Oil : from sunflower.
3. Cereals : occasionally rice or buckwheat.
4. Nuts and seeds : add chestnuts, almonds, sesame seeds, hazelnuts to food.
5. Vegetables : dilute the diet with tomatoes, cucumbers, asparagus, olives, pumpkin dishes, radish, dill.
6. Fruits : do not forget about persimmons, raspberries, lemons, peaches, currants, cranberries, cherries, pears, bananas, watermelon.
7. Drinks : fruit juices. Alcoholic beverages include red and white wine.
8. Spices : in small amounts, add mint, bay leaf, marjoram, cloves, anise, bergamot, paprika, table salt, coriander to food.

Does such a diet contribute to weight loss?

You can practice running, martial arts, boxing, equestrian sports, swimming, aerobics, dancing… But quiet exercises are even contraindicated.

4. Lifestyle. The diet is aimed at a long-lasting result that is not achieved in a short period of time. This diet should be made a way of life.
5. Observation by a nutritionist. The availability of information about this diet and the relative ease of its observance still do not exclude the fact that it is advisable to consult a dietitian. This guarantees a high-quality result and eliminates the appearance of significant disorders in the body.
6. Medicines. Do not take aspirin, which dilutes blood and increases acidity, unnecessarily. Do not abuse sulfamide preparations and antibiotics of the penicillin class.
