A new study at Tulane University found drinking a little wine with dinner may help lower risks of developing type 2 diabetes.
The study was presented at the American Heart Association’s Epidemiology, Prevention, Lifestyle & Cardiometabolic Health Conference and was conducted by Hao Ma et al.
Previous studies have focused on how much people drink and have had mixed results. Very few studies have focused on other drinking details, such as the timing of alcohol intake.
In the study, the team examined the effect moderate drinking may have related to new-onset type 2 diabetes among nearly 312,400 adults from the UK Biobank who self-reported themselves as regular alcohol drinkers.
During an average of nearly 11 years of follow-up, about 8,600 of the adults in the study developed type 2 diabetes.
The team found consuming alcohol with meals was associated with a 14% lower risk of type 2 diabetes compared to consuming alcohol without eating food.
They found the potential benefit of moderate drinking on type 2 diabetes risk was evident only among the people who drank alcohol during meals.
The beneficial association between alcohol drinking with meals and type 2 diabetes was most common among participants who drank wine vs. other types of alcohol.
The researchers say that drinking wine, beer, and liquor had different associations with type 2 diabetes risk.
While a higher amount of wine intake was linked to a lower risk of type 2 diabetes, a higher amount of beer or liquor was linked to a higher risk of type 2 diabetes.
Moderate drinking is defined as one glass of wine or other alcoholic beverage daily for women and up to two glasses daily for men.
That works out to be up to 14 grams, or about 150 ml, of wine a day for women and up to 28 grams, or about 300 ml, of wine daily for men.
The team says a limitation of the study is that most of those participating were self-reported white adults of European descent. It is unknown whether the findings can be generalized to other populations.
