Building Muscle

Proteins are the building blocks of your body. They're everywhere: muscles, bones, skin, enzymes, hormones...
Dietary proteins are used to repairs tissue, regulate water and acid-base balance, support hormone production, and supply energy when food intake is restricted.
Proteins are made of amino acids. There are 20. Nine of these are essential and the other 11 are non-essential. "Essential" means that they are required for health and growth but that your body can't manufacture them. So you must eat them. But don't worry: in most developed countries (US included), people generally eat enough protein to cover their basic needs. On the other hand, non essential amino acids can be produced by the body from the essential ones. Each gram of protein provides 4 calories.
The major sources of protein are:

- Meat
- Fish
- Poultry & eggs
- Dairy products
- Nuts
- Beans
