Moderate alcohol intake may have a positive impact on cholesterol levels, according to some studies. A study published in the Journal of the American College of Cardiology [2] found that moderate alcohol consumption may increase levels of high-density lipoprotein (HDL) cholesterol, also known as "good" cholesterol, which can help reduce the risk of heart disease. However, the same study also found that heavy alcohol consumption can increase levels of low-density lipoprotein (LDL) cholesterol, also known as "bad" cholesterol, which can increase the risk of heart disease.

Another study published in the Journal of the American Heart Association [2] found that moderate alcohol consumption may also have a positive impact on blood pressure, which is closely related to cholesterol levels. The study found that moderate alcohol consumption may help lower blood pressure in people with hypertension, but heavy alcohol consumption can increase blood pressure and negate any potential benefits.

It is important to note that while moderate alcohol consumption may have some potential health benefits, it is not recommended as a primary strategy for improving cholesterol levels or reducing the risk of heart disease. The American Heart Association recommends that men should have no more than two alcoholic drinks per day, and women should have no more than one alcoholic drink per day [3].
