When it comes to nutrition culture, since then things are not easier. Should we eat many carbohydrates, few or none? Is the high consumption of fat ticket to the rapid increases or a shortcut to look like the Michelin doll? And then that word is vital that all cultures known and most feared, the nutrient that everyone knows that the key is to build muscle: protein. Yes, it seems that we all agree that the protein is a crucial part in the diet of culture, but how much you need? Is the FDA (official body of the U.S. to control drugs and food) who recommended intake of 0.8 grams per kilogram of body weight? What about the old culture of appeal "two grams per kilogram? Or should you take as many as possible, trying to reach the 500 grams a day? While this debate on the amount of protein remains hard-fought, experts have agitated the dispute still further with another issue, namely what kind of protein that you take?

This complex dispute has caused two basic schools of thought. Both sides agree that the protein is without doubt the most important macronutrient for the repair and muscle growth, both believe that science gives validity to their views. One side says that the type of protein is not important. The other side argues that such an idea is ridiculous and that his status is of fundamental importance. It is quite interesting that the advocates of the theory of "quantity over quality" call for the cheap soybeans or casein compared with more expensive products from whey. Some supplements sold over the Internet while others write for an assortment of magazines: experts, if they want to call them. Who is right? Consider the facts and see if we can resolve this mess.
