July 13th, 2009A Healthy Fit With Pure Protein
Proteins are crucial parts of all organisms. They are involved in almost all the processes that cells are involved in. Chemically they are organic compounds formed by amino acids. They are derived in the stomach during digestion. They are critical for metabolism. The source of energy, calories, comes mainly from protein, fat and carbohydrates. Dietary sources of protein include meats, eggs, nuts, grains, legumes, and dairy products such as milk and cheese. Proteins are broken down from the tissues continuously by the body. Enzymes break down proteins during digestion in the stomach. It is estimated that men need 56 grams of protein per day and women need 46 grams of protein per day. Protein consumption below this limit leads to protein deficiency.
