What Is Cholesterol?
Cholesterol is a waxy substance made by your liver and found in some foods. It plays vital roles:
- Makes hormones (like estrogen and testosterone)
- Helps build cell membranes
- Supports vitamin D production and bile for digestion
There are two main types:
- LDL (Low-Density Lipoprotein) – “Bad cholesterol” because it can build up in arteries
- HDL (High-Density Lipoprotein) – “Good cholesterol” because it helps clear LDL from the bloodstream
So, question of the day: Does cholesterol alone cause heart attacks and strokes?
