A study published in February 2016 in the journal PLoS One concluded as much. For nearly 11,000 adults, researchers found that low to moderate alcohol consumption (20 or fewer drinks a week for a man, 10 or fewer for a woman) led to higher levels of HDL cholesterol. It also helped get them to healthier overall cholesterol levels, decreasing triglycerides (blood fats in blood) and lowering LDL cholesterol.
An under-valued element of bone and cardiovascular health is the role of Vitamin K2, which many individuals are unknowingly deficient in. Found in the Japanese breakfast delicacy “natto” (fermented soybeans), vitamin K2 not only helps remove calcium from the arteries and soft tissues to prevent atherosclerosis, but it also draws calcium into the bones to prevent the risk of fracture. Nattokinase, an enzyme found in natto, may help to increase HDL levels while lowering total cholesterol and LDL cholesterol levels, according to an Asia Pacific Journal of Clinical Nutrition study.
Furthermore, in epidemiological studies involving over 100,000 individuals, people whose HDL cholesterol levels are below about 40 mg/dL had a substantially higher cardiac risk than those with higher HDL levels. This is the case even when LDL cholesterol ("bad" cholesterol) levels are low. Higher HDL levels have also been associated with a reduced risk of breast, colon and lung cancer.
Can my HDL be too high? It is well known that not all cholesterol is bad for you. Of HDL and LDL cholesterol, HDL packs some great benefits. This MNT Knowledge Center article examines when high HDL cholesterol is good, and whether higher is always better? Learn how to find the right balance along with some healthful ways to achieve high HDL. Read now
And according to some powerful experiments by software engineer-turned-biohacker Dave Feldman, you can actually increase and decrease your cholesterol at will. It all depends on how much fat you eat — and, directly against mainstream dietary knowledge, the correlation is inverted. In other words, eating more fat will actually lower your cholesterol.
