The so-called proteins or simply proteins serve as a building material, the very basis of all living things, the most important and indispensable component of the menu of any person. After all, they are involved in the most important life processes, make up 17 percent of the total body weight of any of the people and are an important part of the cell. Therefore, the role of proteins is very large.
It is from them that new muscle fibers are created, injured or dead body tissues are restored. Thanks to proteins, muscles contract and work, and many vital processes and functions are carried out. This is, first of all, the removal of waste products and the formation of energy. If a person has to eat only food that contains too little fat and carbohydrates, or even starve, then proteins come to the rescue, acting as spare sources of energy and nutrients.
All proteins are made up of a set of specific amino acids. Some of them are synthesized in the body itself and are called essential, but some amino acids can only be obtained with food - and they are called essential. It is proteins that supply the body with such irreplaceable elements. All of them are divided by origin into two groups -animals and plants.
Animal protein is, first of all, dairy products, meat, fish, eggs. Of the meat products, beef, rabbit, pork and poultry contain the most protein. All these are complete products that supply the body with everything it needs. True, some scientists and adherents of vegetarianism are arguing to this day, trying to prove the harm of meat products or the need to limit them in the diet.
Different types of meat differ in protein levels and ease of digestion. Compared to all other animal proteins, the protein contained in eggs is the most complete, easily and completely absorbed by our body and contains the most optimal ratio of all the essential amino acids needed by a person. True, in its use it is worth observing the measure, since eggs are quite high in calories. Fish is less high in calories, and its protein is also easily digested.
Milk protein is extremely useful and is found not only in milk, but also in varying degrees in all dairy products. And this is wonderful, because milk itself is not only digested by adults.
Vegetable protein is the hardest to digest and then the hardest to digest. In addition, it lacks some of the essential amino acids. That is why your diet should be thought out and composed so that it includes not only those products that contain vegetable protein. If a person prefers plant foods, he should take certain nutritional supplements to avoidlack of nutrients. Vegetable protein is found in legumes, coconut, mushrooms, nuts, fruit seeds, grains.
A person needs up to 60 grams of protein per day, and everyone organizes their meals so that they are optimal and balanced in composition. The menu should not prevail, for example, only vegetable protein or meat products. It is difficult for the body to digest and function. Here, as in any other occupation, it is worth observing the measure and adhering to a reasonable approach, only then will it be possible to maintain he alth and excellent condition.
