So-called proteins or simply proteins servebuilding material, the very basis of all living, the most important and indispensable component of the menu of any person. After all, they participate in the most important processes of life, 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 great.
Именно из них создаются новые мышечные волокна, recovered traumatized or dead body tissues. Due to proteins, muscles contract and work and many vital processes and functions are carried out. This, above all, the excretion of waste and energy. If a person has to eat only food that contains too little fat and carbohydrates, or even starve, then the proteins come to the rescue, acting as spare sources of energy and nutritional elements.
Any proteins consist of a set of specificamino acids. Some of them are synthesized in the body and called interchangeable, but some amino acids can be obtained only with food - and they are called irreplaceable. It is the proteins that supply the body with such irreplaceable elements. All of them are divided into two groups - animals and plants.
Animal protein is, above all, dairyproducts, meat, fish, eggs. Of the meat products most contain protein beef, rabbit, pork and poultry. All these are full-fledged products that supply the body with everything you need. True, some scholars and adherents of vegetarianism still argue, trying to prove the harm of meat products or the need for their restriction in the diet.
Different types of meat differ in protein andease of digestion. In comparison with all other animal proteins, the protein contained in the eggs is the most complete, easily and completely absorbed by our body and contains the most optimal ratio of all essential amino acids necessary for a person. True, in its use it is worth keeping to the measure, since the eggs are quite caloric. Less caloric is fish, and its protein is also easily digested.
Milk protein is extremely useful and containsnot only in milk, but also in varying degrees in all dairy products. And this is wonderful, because actually the milk is not digested by adults.
A person needs up to 60 grams of protein per day, andeveryone organizes their meals so that they are optimal and balanced in composition. In the menu should not prevail, say, only vegetable protein or meat products prevail. It is difficult for digestion and functioning of the body. Here, as in any other occupation, it is worth keeping to the measure and adhere to a reasonable approach, only then it will be possible to maintain health and excellent condition.
