Another Round of Drinks, Bartender...but Only One
Moderate drinking, as in one to 13 drinks per week, lowers a person's risk of developing characteristics associated with metabolic syndrome.
With the emergence of an epidemic of obesity and type 2 diabetes (DM) throughout the world, the association of lifestyle habits that may affect the risk of metabolic diseases is especially important. Metabolic syndrome is the name given to a so called 'lifestyle disease', where patients exhibit multiple medical problems including high blood pressure, late on set diabetes, and high cholesterol.
Most prospective studies have shown that moderate drinkers tend to have about 30% lower risk of developing late onset diabetes than do non-drinkers, and moderate drinkers also tend to be at lower risk of developing metabolic syndrome (MS). A cross-sectional analysis of 6172 subjects age 35 -75 in Switzerland related varying levels of alcohol intake to the presence of DM, MS, and an index of insulin resistance (HOMA-IR).

Alcohol consumption was categorized as non-drinkers (0), low-risk (1-13 drinks a week), medium-to-high-risk (14-34) and very-high-risk (35) drinkers. 73% of participants consumed alcohol, 16% were medium-to-high-risk drinkers and 2% very-high risk drinkers
Study findings
Boston University researchers performed a multivariate analysis which revealed that the prevalence of the metabolic syndrome, diabetes and mean HOMA-IR decreased with low-risk drinking and increased with high-risk drinking. Adjusted prevalence of the metabolic syndrome was 24% in non-drinkers, 19% in low-risk, 20% in medium-to-high-risk and 29% in very-high-risk drinkers. Adjusted prevalence of diabetes was 6.0% in non-drinkers, 3.6% in low-risk, 3.8% in medium-to-high-risk and 6.7% in very-high-risk drinkers. These relationships did not differ according to beverage types.
Moderate drinkers also had the lowest weight, tryglycerides, and blood pressure. All drinkers had higher HDL-cholesterol values (good cholesterol) than did non-drinkers.
This is a cross-sectional analysis, so a causative relation between alcohol intake and the metabolic outcomes cannot be assessed. Still, the data supports much that has been shown in prospective studies. Several Forum members commented on potential problems when considering a number of physiologic conditions as the "metabolic syndrome" and focusing therapy on the syndrome; they believed that each metabolic factor should be evaluated and treated singly.
