When assessing the risk between frequency of alcohol drinking and type 2 diabetes incidence, researchers found that only consumption of alcohol 3 to 4 days per week was associated with a reduced risk for developing diabetes, after adjusting for average weekly alcohol amount and other confounders; HR for men was 0.73 (95% CI, 0.59-0.94), and HR for women was 0.68 (95% CI, 0.53-0.88).
Scientists studied data on 70,551 men and women who took part in a Danish survey.
Many of us drink the occasional glass of wine to disconnect our brain at the end of the day.
Overall, the researchers found that men who drink frequently had a 27 percent lower risk and women had a 32 percent lower risk.
The researchers noted that they didn't find an association between binge drinking (defined in the study as drinking five or more drinks at a time) and diabetes risk, but this may be because there weren't enough binge drinkers in the study to observe a link.

The prevalence of diabetes in the U.S.is high - 9.4 percent of the population has the disease, with type 2 being the most common.
Carried out by Professor Janne Tolstrup and a team from the National Institute of Public Health of the University of Southern Denmark, the researchers looked at the effects of drinking frequency on diabetes risk, and a potential association between risk and specific beverage types.
But gin and some other spirits had a massively converse effect on women, with just one drink a day increasing the risk of diabetes by 83 per cent. "Therefore the relationship between red wine and health can be explained by a healthier life style of people who drink in a disciplined manner, by unhealthy effects of non-alcoholic beverages such as soda or juices, or both".
The possible health benefits of drinking moderate amounts of alcohol, according to the US' Mayo Clinic, include reducing your risk of heart disease, ischemic stroke and diabetes. Polyphenols play a role in helping to manage blood sugar.
Binge drinking or heavy drinking is defined as 4 or more drinks for women and 5 or more drinks for men during a single occasion. For example, drinking seven or more glasses of wine per week was associated with a 25 to 30 percent lower risk of diabetes compared with drinking less than one glass of wine per week.
Questionnaires asked survey respondents to give details about their drinking patterns, whether they're abstainers, lifetime and current to reduce the risk of bias as a result of those who abstain because of health issues.
According to the Centers for Disease Control and Prevention, excess alcohol consumption contributes to almost 90,000 deaths annually in the U.S. Binge drinking is associated with liver, kidney and cardiovascular diseases.
