Moderate alcohol consumption: effects on lipids and cardiovascular disease risk

Light to moderate alcohol consumption is associated with a reduced risk of coronary heart disease, as well as ischaemic stroke and possibly type 2 diabetes. Epidemiological and physiological data are in favour of a causal relationship. Proposed protective mechanisms include the stimulation of HDL-mediated processes such as reverse cholesterol transport and antioxidative effects. More well-controlled studies are needed to provide a complete understanding of the complexity of the underlying physiological mechanisms.
