How do you think, which products with the big protein content that are most useful?

Proteins:

It is a very important nutrient, as it enters the building and maintenance of various body tissues, and interferes with the synthesis of some hormones and enzymes without which can not lead to life on the globe.

Proteins consist of 22 structural units containing nitrogen called amino acids. The proteins differ from each other by the number and sequence of amino acids, giving one gram of protein 4 calories.

Proteins are divided according to their nutritional characteristics to:

Full proteins (proteins of high quality): are proteins containing all essential amino acids in sufficient quantity to provide for the body's growing needs and maintenance of damaged tissues. Examples include all animal proteins (except gelatin) such as egg, milk, meat, fish and poultry protein.

• Incomplete proteins (proteins of low quality): proteins that lack one or more essential amino acids and the amount of acids in them is insufficient to meet the needs of the body, such as plant proteins such as wheat, rice, pulses, seeds, etc. Except for soybeans, Full proteins.

* Partially complete proteins: They contain limited amounts of one essential amino acid and as a result are able to maintain life but do not help to grow. Such as some grains, pulses and nuts. Eating cereals and pulses together helps produce a sufficient mixture to make the body's protein.

Protein: Proteins are the main nutrient for the formation of body hormones, musculoskeletal, nervous and blood cells. The body needs them every day so that the body does not store them from other nutrients. Proteins are abundant in meat, fish and birds, as well as milk, cheese and eggs. These proteins are called whole proteins because they contain all acids Amino acids. Proteins are also found in grains such as soybeans, lentils and peanuts. These proteins are called incomplete because they contain only certain amino acids. The average daily requirement of an individual protein is about 60 to 70 grams per day or more accurately it needs one gram of protein per kilogram of body weight. This increases the need for a little during the period of muscle exertion or pregnancy and lactation.
