Final answer:
High levels of HDL (high-density lipoproteins), often referred to as the 'good cholesterol,' are associated with a reduced risk of cardiovascular disease.
Step-by-step explanation:
The student's question is concerned with which type of cholesterol in the blood is associated with a lower risk of cardiovascular disease. High levels of HDL (high-density lipoproteins) in the blood are associated with a lower risk of cardiovascular disease. HDLs are often termed the "good cholesterol transporter" because they help to transport excess cholesterol from the bloodstream to the liver for recycling, thereby preventing plaque formation in the arteries.
In contrast, high levels of LDL (low-density lipoproteins), or the "bad cholesterol transporter," contribute to the buildup of cholesterol in the arteries, increasing the risk of heart disease. Therefore, having a higher ratio of HDL to LDL is considered better for cardiovascular health.
