High cholesterol can have detrimental effects on heart health, as it can lead to atherosclerosis—a condition where plaque builds up in the arteries, restricting blood flow. This increases the risk of heart attacks and strokes. Additionally, distinct types of cholesterol exist; LDL (low-density lipoprotein) is often referred to as "bad" cholesterol due to its association with plaque formation, whereas HDL (high-density lipoprotein) is considered "good" as it helps remove cholesterol from the bloodstream. Maintaining balanced cholesterol levels through diet and exercise is crucial for cardiovascular well-being.
