    Abstract:

    Although moderate alcohol consumption has been associated with a decrease in plasma insulin concentrations, relatively few studies have been conducted to evaluate the effect of alcohol on insulin sensitivity, particularly in nondiabetic, insulin-resistant individuals. Because enhanced insulin sensitivity could contribute to the reported association between moderate alcohol consumption and reduced risk of heart disease and diabetes, we believed it is important to address this issue. Consequently, we evaluated the ability of moderate alcohol consumption to improve insulin sensitivity, as measured by determining the steady-state plasma glucose (SSPG) concentration during the insulin suppression test, in 20 nondiabetic, insulin-resistant individuals. Measurements were made of SSPG, glucose, insulin, and lipoprotein concentrations before and after consuming 30 g of alcohol for 8 weeks, either as vodka (n = 9) or red wine (n = 11). The SSPG concentrations (insulin resistance) decreased by approximately 8% in the total group (P = .08), and high-density lipoprotein cholesterol concentration increased by a mean of 0.09 mmol/L (P = .02). Trends were similar in individuals who consumed vodka or red wine. Men tended to have greater decline in SSPG and increase in high-density lipoprotein cholesterol compared with women. There were no other metabolic changes in fasting plasma glucose, insulin, and triglyceride concentrations. These data demonstrate that 8 weeks of moderate alcohol consumption had minimal impact on enhancing insulin sensitivity in nondiabetic, insulin-resistant individuals, raising questions as to the role, if any, of improved insulin sensitivity in the purported clinical benefits associated with moderate alcohol consumption.
