Final answer:
Engaging in regular aerobic exercise directly reduces the risk for heart disease by maintaining healthy cholesterol levels and weight.
Step-by-step explanation:
The recommendation that would directly reduce the risk for heart disease is C. Engaging in regular aerobic exercise. Aerobic activities significantly benefit cardiovascular health, and it is recommended to be active for at least 60 minutes a day, five days a week. Lack of physical activity can lead to obesity, high cholesterol levels, and ultimately cardiovascular disease. On the other hand, regular exercise helps maintain a healthy weight and lowers cholesterol, thereby reducing the risk of heart disease.
Notably, choosing the right types of fats is crucial for heart health. A diet high in unsaturated fatty acids, particularly omega-3 fatty acids found in cold-water fish like salmon, can reduce the risk of heart disease. Conversely, saturated and trans fats are detrimental as they raise LDL ('bad') cholesterol, and trans fats also lower HDL ('good') cholesterol. Limiting intake of these fats can support healthy blood cholesterol levels and prevent atherosclerosis (the hardening and narrowing of arteries).
