It was often believed that high protein vegetables or high protein diets are extremely beneficial for humans and especially for the athletes. This is far from the truth. High proteins can never make a good diet. It is true that protein is an essential nutrient and it has a major role to play in making our body function properly. However, this does not mean that we require protein in huge proportions. In addition to this, protein supplements are in most cases costly, needless and even injurious for some.
