Maintaining a healthy cholesterol level is crucial because it reduces the risk of cardiovascular diseases, including heart attacks and strokes. High levels of LDL cholesterol can lead to the buildup of plaque in arteries, which hinders blood flow. Conversely, good levels of HDL cholesterol help remove this plaque from the bloodstream. Regular exercise, a balanced diet rich in fiber, and routine health check-ups are essential strategies for maintaining optimal cholesterol levels.
