Proteins are an important part of your bones, muscles, and skin. In fact, proteins are in every living cell in your body. Inside cells, proteins perform many functions, including:
• Helping to break down food for energy
• Building structures
• Breaking down toxins
Proteins are made up of building blocks called amino acids. Your body can make some amino acids but not others. Proteins that you get from meat and other animal products contain all the amino acids you need. These include both those your body can make and those it can't. Proteins from meat and other animal products are known as complete protein.
