Just like a car needs gas to run, the human body needs food. In gas you are limited to just 1 or 2 different types of fuels, but in food you must get a variety of different nutrients in optimum quantities to keep your body healthy.

Proteins are one of the most important nutrients for the body. The body needs proteins to perform many vital functions, and they are also the basic building blocks for the body, needed for bone and muscle formation. That is why you must take protein supplements if you feel that you are not getting enough proteins from food.

Meat products are the richest form of proteins, although most vegetables do not have much protein content, many pulses and grains do have proteins. If you are a vegetarian you should definitely make milk and milk products an important part of your diet.

Protein supplements are vital if you have an active lifestyle. If you work out, or play daily then taking protein supplements is essential to encourage muscle repair and growth. Without protein supplements you run the risk of torn muscles than become a permanently painful entity.

In most cases protein supplements do not have any negative effect on the body and can be taken safely everyday. However if you are using a very powerful form of protein than it might be advisable to consult a dietician or a doctor to make sure that you dont put undue stress on your kidneys.

In many disease proteins play an important part in recovery, for example they are an important part of the crohns nutrition that is designed to prevent damage from Chrons disease.
