1. Definition and basic distribution of proteins
We call these proteins simple. Compound proteins contain phosphoric acid in their composition, and more precisely, the rest of it, carbohydrates or even fats. Proteins include nitrogen, carbon, oxygen, sulfur, and hydrogen. Those that are also combined with other ingredients that are not amino acids at the same time, we call them complex proteins.2. The physiological functions of proteins
Another very important function of proteins is to provide energy, 1 g of protein provides about 4 kcal. As mentioned above, proteins are a component of every living organism cell, but not only. Because they build other chemical compounds, affect cellular and humoral resistance, participate in metabolic processes, transport oxygen, iron or vitamins. They are mainly responsible for their work, they are also necessary to repair damaged tissues of the body. They also affect the basic pH of the blood because of their ability to stimulate. Because proteins build up the basic functions of the cell component of the organism, it is one of the essential components for the development and breakdown of hormones.3. The body's need for protein
In addition to the quantity of protein, attention should be paid to its quality. What should you pay attention to when calculating the demand for this nutrient? Each person has an individual need for protein. This involves the need to supply all the essential amino acids. Protein is constantly exchanged in the body, so it is necessary to supplement it daily with the diet.4.

This is due to the build-up of new cells, including the developing fetus, the fetal membranes, an increase in fat-free weight. It is also important to determine the physiological status when estimating the appropriate amount of protein. The protein requirement in pregnant women is 1.2 g/kg body weight/day, while during lactation it is 1.45 g/ kg bodyweight/day. This is necessary because physiological conditions such as pregnancy or lactation require higher protein intake.5.

However, in some cases, when kidney disease is deficient, the amount of protein needed to be reduced significantly to improve the functioning of these organs. Increased protein intake is intended to cover the loss of lean (muscle) body weight that has occurred as a result of the disease.6. Body weight
For example, a woman weighing 60 kg should provide 48 g of protein per day, since 1 kg of her body weight corresponds to about 0.8 g protein.7. It's physical activity
The recommended protein intake for endurance athletes is 1, 21, 4 g/kg body weight and 1, 41, 8 g/ kg body weight per day. This is due to the increase in lean body mass and the need to repair muscle micro-damages associated with intense physical activity. People who exercise very often and intensely can and should increase the amount of protein during the day.8. The nutritional value of protein
It is important to determine the quality of protein needed and to include in the diet products that are able to meet the demand for all essential amino acids.9. Sources of protein in food
In addition, full-value proteins provide amino acids in such proportions that the body is able to make the most of them for systemic protein synthesis, growth processes, and nitrogen balance. So where do we find full protein? Full protein supplies eggs, meat, fish, as well as milk and dairy products. They do not provide all the essential amino acid such as walnut, tryptophan, lysine and methionine. These include soybeans, beans, and so on.10. Consequences of lack or excess protein in the diet
Protein metabolism in the human body is closely linked to the supply of energy in the diet. This affects the protein economy, leads to protein malnutrition, and disorders in body functioning. However, there is a risk of long-term hunger resulting from burns, diarrhea, or increased protein loss. This also leads to a decrease in the functioning of the digestive system, as the body's amino acids begin to grow, as well as a reduction in the amount of energy that can be absorbed by the body. This can be seen as an increase in the distribution of nutrients from the body to the body, and it is very important to observe how much protein and protein is involved in this diet.
