Drinking wine with meals reduces the risk of developing type 2 diabetes
9th March 2022
Moderate alcohol intake is defined as the consumption of 1 glass of wine or other alcoholic beverage per day for women and up to 2 glasses per day for men. According to scientists, this amounts to up to 14 grams, or about 150 ml of wine per day for women and up to 28 grams, or about 300 ml of wine per day for men. Clinical trials have also demonstrated that moderate alcohol consumption may have some health benefits, including glucose metabolism. However, it remains unclear whether the benefits of glucose metabolism translate into a reduction in the incidence of type 2 diabetes.
The study, published in the journal of the American Heart Association, included data on the health status of almost 312,400 people taking alcohol.
Materials and methods of research
The study included data on the health status of almost 312,400 people taking alcohol.
Scientists specifically studied the effect of moderate alcohol consumption on the development of type 2 diabetes among all study participants for about 11 years (between 2006 and 2010). The data of almost 312,400 adults from the British Biobank were analyzed, who themselves reported that they regularly drink alcohol. At the time of inclusion in the study, the participants did not have diabetes, cardiovascular disease or cancer. People who reduced alcohol consumption due to illness, doctor’s recommendation or pregnancy were excluded from the study. The average age of the participants was about 56 years, slightly more than half of the adults were women, and 95% were Caucasian adults.
Moderate wine consumption reduces the risk of type 2 diabetes
The results of the study demonstrate:
On average, over 11 years of follow-up, approximately 8,600 adults who participated in the study developed type 2 diabetes;
Drinking alcohol while eating was associated with a lower risk of developing type 2 diabetes — by 14% compared to drinking alcohol without eating;
The potential benefit of moderate alcohol consumption in relation to the risk of type 2 diabetes was evident only among people who consumed alcohol during meals, although this study did not collect specific data on meal times;
The beneficial association between drinking alcohol while eating and type 2 diabetes was most common among participants who drank wine compared to other types of alcohol;
The consumption of wine, beer and alcoholic beverages is variously associated with the risk of developing type 2 diabetes. While higher wine consumption was associated with a lower risk of type 2 diabetes, drinking large amounts of beer or spirits was associated with a higher risk of type 2 diabetes.
