Protein Facts

Protein Facts
Protein is a nutrient that is essential for the human body as it is required for building, maintaining, and replacing tissue. When protein is consumed it is broken down during digestion into amino acids. These amino acids are then used for maintaining muscles, organs, blood, and bones. There are several amino acids that the body can make, but there are nine that must be consumed in protein-rich foods. Although it is important to get enough protein in the diet, too much can be damaging to the kidneys and liver. Protein can be consumed in animal or plant foods, making it possible for vegetarians and vegans to consume enough protein to maintain good health.
