Final answer:
Moderate alcohol consumption increases levels of HDL, the "good cholesterol transporter," which helps remove cholesterol from the body. To maintain healthy cholesterol levels, one should also consume omega-3 fatty acids, which lower LDL and increase HDL. Omega-3s play a crucial role alongside moderate alcohol to support heart health.
Step-by-step explanation:
Consumption of moderate alcohol has been shown to increase levels of high-density lipoprotein (HDL), commonly referred to as "good cholesterol transporter." This is beneficial because HDL helps to carry cholesterol from various parts of the body back to the liver, where it can be removed. This process can help to maintain healthy total blood cholesterol levels which should ideally be under 200 mg/dL. For a more favorable lipid profile, a higher HDL level is preferable, as it helps prevent the accumulation of cholesterol in the arteries, which lessens the risk of heart disease and heart attack.
On the other hand, low-density lipoprotein (LDL), or the "bad cholesterol transporter," carries cholesterol from the liver to other tissues. High levels of LDL can contribute to plaque buildup in arteries, which can lead to atherosclerosis and potentially a heart attack or stroke. Avoiding saturated and trans fatty acids in your diet is crucial because they tend to raise LDL levels and decrease HDL.
The consumption of omega-3 fatty acids, such as alpha-linolenic acid, helps lower LDL and raise HDL, supporting a healthy cholesterol balance. Thus, while moderate alcohol can increase HDL, one should also focus on consuming foods high in polyunsaturated fatty acids to maintain optimal cholesterol levels.
