Reference: Dr Mercola Website Newsletter, Monday 26 March 2012There is a major misconception that you must avoid foods like eggs and saturated fat to protect your heart. While it's true that fats from animal sources contain cholesterol, this is not necessarily a health hazard. As I've discussed on many occasions, your body actually requires cholesterol, and artificially driving your cholesterol levels down is nearly always doing far more harm than good. Every cell in your body needs cholesterol. It helps to produce cell membranes, hormones, vitamin D and bile acids that help you to digest fat. Cholesterol also helps in the formation of memories and is vital for your neurological function. In other words, dietary cholesterol is your friend, not your enemy.Besides, numerous studies support the conclusion that eggs have virtually nothing to do with raising your cholesterol anyway. For instance, research published in the International Journal of Cardiology showed that, in healthy adults, eating eggs daily did not produce a negative effect on endothelial function, an aggregate measure of cardiac risk, nor an increase in cholesterol levels.
