The fitness instructor told me to eat egg whites instead of egg yolks. Why?
There is a lot of protein in egg white and high cholesterol in egg yolk, so you can't say that you don't eat it at all. In fact, as long as you are not very fat and have no cardiovascular disease, there is basically no problem in eating whole eggs, which will be more conducive to protein's absorption. Normal adult men have two whole eggs of cholesterol every day for their own supplement, decomposition and absorption. Women are one.
