Final answer:
Proper nutrition and exercise are essential for preventing cardiovascular disease.
Step-by-step explanation:
Proper nutrition and exercise play a crucial role in preventing cardiovascular disease. Regular physical exercise helps improve cardiovascular health by reducing risk factors such as high blood pressure, high cholesterol, excess body weight, and low insulin sensitivity. Additionally, it promotes the health of blood vessels by reducing plaque formation and blood pressure. A healthy diet, on the other hand, lowers the risk of cardiovascular disease by preventing high cholesterol levels, obesity, and other conditions associated with poor eating habits.
