How do we define good and bad cholesterol in our body?

Good cholesterol is primarily represented by high-density lipoprotein (HDL), which helps transport cholesterol from the arteries to the liver for removal, thereby reducing the risk of Heart disease. Bad cholesterol, on the other hand, is low-density lipoprotein (LDL), which can build up in the walls of arteries, leading to plaque formation and increased cardiovascular risk. Maintaining a healthy balance between HDL and LDL levels is crucial for overall heart health.
