The word protein is actually derived from the Greek and means "primary importance". Proteins are very important because they are the essential building blocks of life and are the structures of the body, such as skin, hair, muscles and bones. Protein would not exist without these body parts and are easily decomposed.
We get protein from eating protein-rich foods such as red meat, fish, poultry, eggs and dairy products.
