White wine consumption decreases weight gain in rats

Introduction: Although alcohol is a rich source of energy (7.1 kcal/g), there are conflicting results on its association with weight gain. In animals, both ethanol and red wine did not promote body weight gain in comparison to water. Effects of white wine on weight gain and food intake in rats have not been investigated. In this study we investigated the white wine effects on weight gain in younger fast growing, and older slower growing rats following 4 weeks consumption trial. Materials and methods: Younger group consisted of 20, one month old Sprague Dawley male rats, weighing 150-200 g, and grown group included 20 rats, three months old, weighing 400-500 g. The groups were further divided into wine and water-only-drinking controls (N=10 per group). The rats were fed a standard pellet diet ad libitum. The wine drinking rats were offered ad libitum Grasevina, Krauthaker winery, 2015, 13.0 vol% alcohol, 24 hours/day for 4 weeks with daily inclusion of tap water for 6 hours. Fluids intake was recorded daily. Body weight and food intake were measured weekly. The results are reported as means ± SD. Data were compared by the Student t-test, with the level of significance set at P<0.05. Results: After 4 weeks of wine consumption both young and grown rats gained less weight in comparison to controls (P=0.003 and P=0.016, respectively). There was no difference in total daily liquid intake whereas weekly and total food intake was reduced in all wine-consuming rats. Conclusion: White wine consumption decreases weight gain in rats regardless of their age and initial body mass. Additional calories provided by wine were compensated for by reduced intake of food.
