“A number of studies [have] already found that diabetes risk was lower among those with a light to moderate intake as compared to nondrinkers and those with a heavy intake,” Janne Tolstrup, who led the research team from the University of Southern Denmark’s National Institute of Public Health, told Wine Spectator in an email. “We aimed at testing if drinking patterns, measured in frequency, played a role in this association.”
The study, published in the diabetes research journal Diabetologia, used data from the Danish Health Examination Survey, a 2007 survey of the diet, smoking habits, alcohol intake and physical activity of Danish adults. From the data, researchers identified 70,551 diabetes-free participants (28,704 men and 41,847 women) and tracked their self-reported drinking habits and health over the course of five years.
Tolstrup warns against changing your alcohol consumption levels or frequency just because of this study, however. “Our results cannot be used for giving advice to patients or anyone else,” she said. “We focus narrowly on a single disease—diabetes—and alcohol is associated with an increased risk of many, many diseases.”
