What is it?
Cholesterol is a fat like substance made by your liver that is essential to a wide range of body functions including making hormones and digesting fatty foods.
Your body is able to make all the cholesterol it needs so you should aim to keep dietary cholesterol low. Food that is high in cholesterol includes meat, seafood and dairy products.
Cholesterol is divided into HDL-cholesterol ("good" cholesterol) and LDL-cholesterol ("bad" cholesterol). It is the ratio of these different types of cholesterol that is important in determining your future risks of heart attacks and strokes.
