16 Apr
Over the past number of years the word ‘cholesterol’ has become a common term. However, what is it really and why all the talk about it?
What Is Cholesterol
Cholesterol is a soft, waxy substance found among the fats (lipids) in the blood. Produced in the liver, this slippery substance is not a fat, but actually a steroid and plays a central role in many biochemical processes. Daily the liver produces about 1,000 milligrams of cholesterol.
