(WineSpectator) - Several studies have found that moderate alcohol consumption helps prevent type-2 diabetes. A new report from a team of European researchers supports that but also finds that the benefits depend on a lot of factors, including the gender of the wine drinker and their weight. For this study, scheduled to be published in the Journal of Internal Medicine, researchers at numerous medical centers in Northern European countries, as well as Spain, Italy and the United Kingdom, pooled resources to examine the lifestyle habits of nearly 30,000 people. Those subjects are part of a larger, ongoing study, the European Prospective Investigation into Cancer and Nutrition (EPIC), which is investigating the impact of food habits on the rate of chronic disease development in more than 520,000 participants.
