Abstract

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 Müller-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 (Müller-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; Müller-Thurgau group: P=0.003; Pintes group: P=0.002) and AST (aspartate aminotransferase; Müller-Thurgau group: P=0.003; Pintes group: P=0.02). Epidermal growth factor (EGF) levels increased significantly in both groups (Müller-Thurgau group: P=0.004; Pintes group: P=0.001). The plasma reducing capacity increased significantly upon the consumption of both sorts of wine (Müller-Thurgau group: P=0.002; Pintes group: P=0.001). In patients consuming Müller-Thurgau there was a significant decrease of total cholesterol (5.4±1.4 vs. 4.9±1.2 mmol l-1; P=0.006) and LDL-cholesterol (3.9±1.1 vs. 3.6±1.2 mmol l-1; P=0.04) levels. In the Pintes group we found no significant difference either in total cholesterol (5.1±0.6 vs. 5.0±0.7 mmol l-1; P=0.25) or LDL-cholesterol (3.6±0.6 vs. 3.6±0.6 mmol l-1; P=0.5) concentrations. The results of our study confirm that moderate consumption of white wine increases insulin sensitivity and EGF levels in persons with metabolic syndrome.
