Because egg yolks contain cholesterol, it was thought that eating them would raise one's cholesterol. However, it was later discovered that eating the cholesterol did not cause a rise in blood cholesterol in the people that ate them. There are still people who believe eggs are bad. I work with a guy who only eats egg whites if he has eggs. He also won't eat anything fried. He still believes in the old food pyramid and eats lots of carbs and has a nice little belly on him.
Right. What most people don't know is our own body produces cholesterol which is the mother hormone. From that, hormones are than separated into testosterone, estradiol, cortisol, growth hormone, and many others.
Triglyceride fat levels are now the main concern for heart disease and other physical problems over cholesterol.
