Physical activity plays a crucial role in managing cholesterol levels in kids. Regular exercise has been shown to increase the levels of high-density lipoprotein (HDL) cholesterol, also known as "good" cholesterol, while decreasing the levels of low-density lipoprotein (LDL) cholesterol, or "bad" cholesterol.

For example, a study published in the American Journal of Epidemiology found that children who engaged in at least 60 minutes of moderate to vigorous physical activity per day had higher levels of HDL cholesterol and lower levels of LDL cholesterol compared to their sedentary counterparts.

Furthermore, physical activity can also help in weight management, which is closely linked to cholesterol levels. Children who maintain a healthy weight through regular exercise are less likely to develop high cholesterol levels.

Encouraging kids to participate in activities such as swimming, cycling, running, or team sports can have a positive impact on their cholesterol levels. Additionally, promoting an active lifestyle from a young age can establish healthy habits that persist into adulthood.
