Final answer:
Moderate alcohol consumption is indeed known to increase levels of HDL, or 'good cholesterol.' HDL functions as a transporter to assist in the removal of cholesterol from the bloodstream, helping prevent arterial plaque buildup which can lead to heart disease.
Step-by-step explanation:
The statement that moderate alcohol consumption can actually increase the blood levels of good cholesterol, or HDL, is true. HDL, or high-density lipoprotein, is often referred to as the "good cholesterol transporter." It plays a critical role in transporting excess cholesterol back to the liver for recycling, helping prevent plaque formation in the arteries and reducing the risk of heart disease. A healthy lipid profile generally includes low levels of LDL ("bad cholesterol transporter") and higher levels of HDL.
Regular consumption of polyunsaturated fatty acids, including omega-3s, is beneficial as they lower LDL and elevate HDL. Conversely, saturated and trans fats increase LDL and decrease HDL, negatively impacting cholesterol levels. Recent studies, however, challenge the simplified view of good versus bad cholesterol and the direct association between saturated fats and cardiovascular disease risk.
