 Protein foods
   What are the proteins to the human body? Without exaggeration, one can answer that's all. Indeed, the protein - is building the foundation for growth and repair any and all biological tissues. No protein impossible none enzymatic activity because enzymes consist of all protein components. If an analysis of any one hormone, it will be white. Humoral factors (plasma) immunity Immunity - types and characteristics in children in adults  Immunity - types and characteristics in children in adults
   are complex protein complexes. Reducing any and all muscles, including breathing muscles, there is only due to the specific interaction of two proteins: actin and myosin.

Finally, a well-known hemoglobin Hemoglobin: worse - low or high?  Hemoglobin: worse - low or high?
 , Which is composed of erythrocyte carries oxygen vital - is also a complex with the quaternary protein structure. This short list is enough to understand the impossibility of living organism in the absence of proteins.

Every day the human body uses for its own needs a certain amount of protein, so to restore the necessary protein needed daily stock replenishment of organic material .  The main route of protein - it is food .  However, the protein - a very complex high molecular weight component, which is to assimilate must first be shaded into smaller fragments .  These building blocks are amino acids - protein structural units .  Currently, nearly a hundred known amino acids, but in the metabolism of the human body actively involved only about twenty .  Some of them with insufficient intake from the outside can be synthesized in the body on their own, others do not have this ability, so amino acids are classified as essential and nonessential .  Accordingly, the essential amino acids must come exclusively from food .

How much protein should be consumed for normal functioning of all body systems? Finding an answer to this question lasted more than a decade .  And in the nineteenth - twentieth centuries the daily requirement of protein ranged from 26 to 136 grams .  Such a huge razbezhnost reviews explains how the reactionary views of some scientists, acting on the orders of the government, and insufficient account of all the possible reasons that could change the daily protein requirement for one side or another .  Currently considered sufficient 100 - 120 grams of protein per day .  More precisely, this number is displayed proportional ratio of protein to body weight, so we can identify "their" need for protein, based on the fact that for 1 kg of body weight should fall 1, 3 - 1, 5 g protein .  However, as has been mentioned just above, the required amount of protein a day may vary .  For example, when a physical or mental stress the need for protein increases, so plays an important role lifestyle of each individual and his profession .  Approximately ten percent of the need to increase the protein diet for pregnant women and twenty - for nursing mothers .

Lack of protein in the body leads to a variety of pathological conditions associated with the failure of enzyme systems, hormonal imbalance and other factors. The man developed rapidly alimentary (ie food) dystrophy, brain damage, deteriorating work forming organs, liver and many other systems. Especially protein deficiency adversely affects the child's body: the child lags behind in growth, physical and mental development. When protein deficiency, besides the fact that the child is not enough protein developed specific cell deficiency in pituitary brain region. The function of these cells is to produce growth hormone responsible for the growth of the child's body. When severe protein deficiency is possible death from dystrophy.

However, overeating protein foods also should not be. Since this amplified putrefaction in the intestine, leading to the formation and absorption of toxic elements in the blood dissolution.

Most are rich in proteins, legumes and dairy products, eggs, meat and fish. Least of all the proteins in berries and fruits. In addition, in animal products on average contains more protein, they still have a well-balanced amino acid composition that is important for proper digestion and assimilation of protein components.
