Beneficial effect of moderate white wine consumption on insulin sensitivity in patients with metabolic syndrome

The effect of moderate alcohol consumption on insulin sensitivity is actually a topic of intense research nowadays. In this study we investigated the effect of moderate consumption of white wine in subjects with metabolic syndrome. Thirty-two patients with metabolic syndrome participated in this prospective, randomised, double-blind study. The subjects received either Muller-Thurgau (n=14) or Pintes (n=18) sort of wine for 4 weeks. Male and female subjects consumed 300 ml wine (30 g alcohol) and 200 ml wine (20 g alcohol) per day, respectively. Clinical and laboratory parameters were determined before and after the period of wine consumption. The HOMA-IR showed a significant decrease upon the consumption of both sorts of wine as compared to the baseline (Muller-Thurgau group: 1.85±2.1 vs. 1.06±0.6; P=0.03; Pintes group: 2.28±2.04 vs. 1.08±0.6; P=0.002). Four weeks of wine consumption lead to significant decreased of ALT (alanine aminotransferase; Muller-Thurgau group: P=0.003; Pintes group: P=0.002) and A...
