Alcohol consumption can affect cholesterol levels, but the extent of the impact depends on the amount and frequency of consumption. According to [2], moderate alcohol consumption, which is defined as one drink per day for women and up to two drinks per day for men, can increase levels of high-density lipoprotein (HDL) cholesterol, also known as "good" cholesterol. HDL cholesterol helps remove low-density lipoprotein (LDL) cholesterol, also known as "bad" cholesterol, from the bloodstream, reducing the risk of heart disease.

However, excessive alcohol consumption can have the opposite effect and increase levels of LDL cholesterol, leading to a higher risk of heart disease. [3] notes that heavy drinking, which is defined as more than three drinks per day for women and more than four drinks per day for men, can cause inflammation and damage to the liver, leading to an increase in LDL cholesterol levels.

Additionally, alcohol consumption can interact with cholesterol-lowering medications, such as statins, potentially leading to liver damage and other adverse effects. [1] recommends avoiding alcohol while taking cholesterol-lowering medications.

In conclusion, moderate alcohol consumption can have a positive effect on cholesterol levels, while excessive alcohol consumption can have a negative effect. It is important to consume alcohol in moderation and avoid it altogether while taking cholesterol-lowering medications.
