one of the main nutrients necessary for human life is protein (protein). it is proteins that give about 15% of the society the amount of food energy a person receives per day. this amount may not seem very large, but protein is an extremely necessary building material. proteins must be obtained
from food every day, because their reserves in the body are not formed independently. the amount of protein depends on the value of a particular food protein, i.e. from its amino acid composition. amino acids determine the structure and function of a protein. in this regard, it is necessary that the
main part of food proteins be animal proteins, namely eggs, dairy products, poultry meat, lean pork, lamb, beef, fish, etc. from these sources, a person can get everything they need with minimal energy. it is useful to make your diet in such a way that at least 75% of the diet is made up of products
of plant origin, and 25% is allocated to the share of animal products.

man by nature feeds on mixed food, while being carnivorous. meat is considered one of the most complete food products, giving material for muscle growth, so necessary for our body, as well as providing the body with
strength and vitality.

of the meat components up to 20% form proteins, and most of it is water (70-75%). also in the composition of the meat there are fats and minerals. the fatter the meat, the less protein it contains, and vice versa. the essential amino acids found in meat proteins
are presented in a ratio suitable for humans. animal proteins are digested more fully and quickly, and the body is easier to assimilate their components.

the meat contains a very small amount of carbohydrates. here there is glycogen, which is called "animal starch". it is more contained
in the meat of wild animals. also, the value of meat is the presence of several minerals. basically, they are present in lean meat and juices flowing from meat. meat contains sodium, phosphorus, potassium, magnesium, sulfur compounds and especially valuable iron. iron contained in red meat is well
absorbed by the body, and from the point of view of these indicators is an indispensable component necessary for the formation of blood and hemoglobin. that is why it is believed that a person should eat red meat at least 2-3 times a week. to get the required amount of iron, a small amount of meat
is enough - about 50 grams at a time. vitamins of group b are also present in meat. vitamin b12 is considered to be the most important from the point of view of benefits for blood circulation, and vitamin a, which has the ability to dissolve fats, is also present in fatter meat.

based
on the recommendations of local nutritionists, 100 grams of meat or fish should be eaten per day, while more massive men should eat twice the amount. the diet must include meat products. each person will be able to choose for himself the options that are ideally suited to his tastes and needs.
