What is Cholesterol?
- Cholesterol is a fat-like, waxy substance, made by the liver to protect nerves, producing cell membranes and certain hormones
- However, excess cholesterol can deposit in the arteries and form plaque which eventually leads to coronary artery disease
- Most of the cholesterol is made by the body and some cholesterol comes from foods such as eggs, meats and dairy products
- There are 3 types of cholesterol:
- Low Density Lipoprotein (LDL) – usually known as bad cholesterol
- High Density Lipoprotein (HDL) – usually known as good cholesterol
- Triglycerides are a form of fat mainly obtained from our daily diet
