Fitness can not eat egg yolks, the main reason is that egg yolks contain a lot of cholesterol and fat, and to be greater than the content of the protein, fitness people eat egg yolks will make fat increase, and muscle increase is less, is more fat than muscle, so that the fitness effect does not appear. Personally, I think fitness people can eat a small amount of egg yolk, egg yolk contains not only fat, but also rich in lecithin, for human brain development has a very large role in promoting. The cholesterol in the egg yolk is a relatively small amount of material in the human body intake of food occupies a very small proportion, you can eat 3-5 eggs fitness, eat 1 egg yolk to supplement the relevant nutrition, in order to make a balanced nutrition, for the body and fitness itself is beneficial.
