Protein

Protein is made of chains of amino acids, which provide the building blocks (amino acids) for enzymes and other proteins within the body. It is needed for cells to grow and to repairs or replaces cells and tissues. In fact most all the parts of our bodies are made from protein. Protein also provide calories to provide energy to the body whenever we do not get enough calories from fat and carbohydrates.

Our body does not manufacture certain amino acids known as “essential amino acids”. We must obtain it from our diet. Foods that come from animals, such as fish, chicken, beef, eggs, milk, cheese, and yogurt contain all of the essential amino acids. Plant foods, such as rice, beans, peas, wheat and corn may be lack of one or more of the amino acids.

Protiens that’s contain all “essential amino acids” are known as complete proteins.Proteins that lack at least one or more of the “essential amino acids” are known as Incomplete Protein. However Incomplete proteins can be mixed together to make a complete protein
