Maintaining healthy cholesterol levels is significant for reducing the risk of heart disease and stroke. High levels of low-density lipoprotein (LDL) cholesterol can lead to plaque buildup in arteries, raising the likelihood of cardiovascular issues. Conversely, high levels of high-density lipoprotein (HDL) cholesterol are protective. Lifestyle modifications such as a balanced diet low in saturated fats, regular exercise, and healthy weight management can help regulate cholesterol, promoting heart health and longevity.
