I eat fish, chicken, eggs, soy and beef. Why do I still need whey protein?

Healthy diets should regularly include high quality, low fat sources of protein. Calories do count and you want to make sure that you are getting the most benefit from the quantity of energy you consume. On a gram-to-gram basis whey protein isolate delivers more essential amino acids to the body than other proteins, but without the fat or cholesterol. Nutrition experts recommend a diet with a variety of protein foods especially when growing, exercising or building muscle to aid recovery and repair. In these cases, for optimal results, providing a protein source that's fast-absorbing and convenient, whey protein is ideal.
