WHAT IT IS AND WHY YOU NEED IT
Protein is the major structural and functional component of all cells in your body. Proteins literally play a necessary role in many of the biological processes that allow you to live and function. Not to mention, about 25 percent of your muscle mass is made up of protein—and the rest is made up of water and glycogen (your body’s stored form of carbohydrates). So it’s no wonder why so many diets place a heavy emphasis on protein. But the reason you need to eat so much is simple: Unlike other nutrients, your body can not assemble protein by combining other nutrients, so enough must be consumed in your daily meals in order to achieve your desired health and appearance.
