The Protein

Main source of protein is meat. But in the environment, proteins are not found only in meat, although most of them are found in the animal kingdom.

Lack of protein in the body can give:
- Disturbances of growth and nutrition;
- Reduced resistance to infection;
- Occurrence of anemia;
- Edema;
- Decreased physical activity and mental.

Excess of protein in the body can lead to:
- The occurrence of disease (gout);
- Intoxication with protein.

Proteins are processed in the digestive tract, under the influence of different enzymes, which are called amino acids. In fact they are absorbed in the intestine such as amino acids, which contribute directly to growth and repair. Protein containing all essential amino acids are called complete proteins, such as those found in foods such as:milk, eggs, lean meat, cheese... Proteins do not contain all the essential amino acids are called incomplete proteins, such as:peas, beans, corn...
Caloric value of proteins is the following: 1 gram of protein, by burning in the body, produce 4 calories.
