Proteins are the bricks and mortar of our body. They are found in our muscles, bones, skin, hair, blood and internal organs. There are 10’s of thousands of different kinds of protein, but they are all made up from about 20 different amino acids linked together in different combinations. We can create from scratch all but 8 of these amino acids. We must get these 8 “essential” amino acids from our diet to survive.
Foods that contain all amino acids are called Complete protein sources.
Foods that are missing some amino acids are called Incomplete protein sources.
Every gram of pure protein supplies our body with 4 calories.
