Protein is so important in the development of muscle as well as hair, nails, and other organs in your body. But that does not mean you should start eating chicken 5 times a day. Too much animal protein (including milk products and eggs) can cause your body stress as well as add extra fat, even if you are eating lean meat or drinking fat free skim milk. Achieve your daily protein requirement through grains like 100% whole wheat bread, legumes (beans), green veggies (broccoli is loaded with protein), nuts, sprouts, and seeds. These sources provide calcium, fiber, and other vitamins and mineral that are not in animal protein.
