Proteins

Proteins are the building blocks of the body. The body needs proteins to produce hormones, enzymes, hemoglobin and muscle. The good thing about proteins is that if you eat more than the body needs then it is excreted. It is recommended by the authors that proteins should make up approximately 15% of the total diet. This is about 2-3 times more than the body will need and use. However it is better to eat more protein than you need than it is to eat more fat and carbohydrate than you need because the body excretes the excess. Examples of good sources of protein are white meats and egg white. Other meats are also good sources of proteins but they also have higher levels of fat. However red meats are fine as long as they are not eaten excessively.
