Final answer:
High-density lipoprotein (HDL) is more affected by physical activity than diet, acting as a good cholesterol transporter and playing a key role in heart health.
Step-by-step explanation:
Among the blood lipids listed, high-density lipoprotein (HDL) is influenced more by physical activity than by nutrition modification. This is because HDL functions as a transporter that moves cholesterol out of the bloodstream and into the liver, thus preventing arterial plaque formation. The process by which HDL cholesterol is increased is thought to be enhanced more effectively through regular physical activity as opposed to dietary changes alone. Regular exercise can help raise the levels of HDL cholesterol in the body, contributing to better heart health.
