Protein diet - what is it?

Despite the fact that the most rational diet is considered to be balanced, that is, consisting of a thoughtful amount of proteins, fats and carbohydrates, there is a category of people who like to divide food products according to their belonging to certain useful components. This is how the idea of a protein diet appeared, where the predominant position in the composition of products is occupied by products with a high content of proteins (plant or animal). Which proteins (plant or animal origin) to give preference to, a person decides for himself.

In order to follow a protein diet, you need to know which foods and in what quantities contain protein substances. How much protein should you consume per day to avoid getting a disease associated with a monotonous diet. Or not to aggravate the course of the disease, in which excess protein products are extremely harmful to the body.

Sources of animal proteins are:

Meat (poultry, pork, beef, lamb, hare, game);
Fish and seafood (shrimp, shellfish, squid, crab, lobster, and crayfish);
Eggs;
Milk and dairy products (cheeses, fermented baked milk, yogurt, feta cheese, cottage cheese, sour cream, butter, etc.).

All protein products of animal origin are interchangeable, since each of these products contains the required amount and a complete set of amino acids necessary for human health. But the most valuable protein products are eggs and dairy products, since nature has laid a complete set of substances necessary for growing offspring in these products. If there are no contraindications for health reasons, then a person gets a greater percentage of protein food from meat products, and then from fish products. For an adult, meat is the most favorable protein product, since in addition to proteins, it contains many minerals and maintains the correct blood composition. With low-intensity physical activity, a person needs to consume 5.3 - 7 ounces of meat or meat derivatives per day. But overeating meat can lead to many diseases affecting the liver, kidneys, cardiovascular system and nervous system.

In its chemical and biological composition, fish is close to meat, but has less fat. This makes such a food product as fish very valuable in cases of diet for the elderly or for low-fat diets for weight loss.

Eggs, in terms of their importance in nutrition, can completely replace meat and are suitable for nutrition in old age, and in childhood and adolescence, eggs are simply vital. Milk and milk derivatives have an ideal mineral composition and are products that can replace meat, fish and eggs.

But the ideal protein diet using protein foods of animal origin is based on a combination of all types of products containing animal protein. In this case, the distribution of these products throughout the day is important.

A number of products are sources of vegetable protein:

Bread and products made from flour and grain crops;
Cereal porridges;
Potato;
Legumes (soybeans, beans, peas and others).

Oddly enough, bread (grain baked goods) and potatoes are interchangeable sources of vegetable protein. Potatoes contain less protein than bread, but this potato protein has greater biological activity than grain protein. Also, unlike bread, potatoes are rich in vitamin C.

Since protein is a valuable biological substance for the full life of the human body, the use of elements of the Protein Diet in the diet is quite justified. But a complete transition to the Protein Diet is undesirable, since a balanced human diet consists not only of protein products, but also of fats, carbohydrates and plant fiber.
