Which of the following is a major risk factor for cardiovascular disease?

A sedentary lifestyle is indeed a major risk factor for cardiovascular disease. When individuals lead a lifestyle characterized by physical inactivity, it can lead to a host of health issues, including obesity, high blood pressure, and elevated levels of negative cholesterol, all of which contribute to the development of cardiovascular disease. Regular physical activity is crucial for maintaining heart health, as it helps to strengthen the heart muscle, improve circulation, and manage body weight.

While a high fiber diet, regular exercise, and low cholesterol levels are beneficial for cardiovascular health, they do not represent risk factors in the same way that a sedentary lifestyle does. In fact, a high fiber diet and regular exercise are key components in reducing the risk of heart disease, while low cholesterol levels are typically associated with better cardiovascular health rather than risk. Therefore, understanding the impact of lifestyle choices on heart health is vital for reducing the risk of cardiovascular disease.
