What are the differences between LDL and HDL cholesterol, and how can you lower your levels of bad cholesterol (LDL) to improve your heart health?

LDL (low-density lipoprotein) cholesterol is considered "bad" because it can build up in arteries, leading to Heart disease. HDL (high-density lipoprotein) cholesterol is considered "good" because it helps remove LDL from the arteries. To lower LDL levels and improve heart health, you can:

1. Eat a healthy diet low in saturated and trans fats
2. Exercise regularly
3. Maintain a healthy weight
4. Quit smoking
5. Limit alcohol intake
6. Take prescribed medications if necessary.
