People who drink three to four times a week are less likely to develop type 2 diabetes than those who never drink, Danish researchers suggest.

Wine appears to be particularly beneficial, probably as it plays a role in helping to manage blood sugar.

They surveyed more than 70,000 people on their alcohol intake – how much and how often they drank.

But experts said this wasn’t a “green light” to drink more than recommended.

And Public Health England warned that consuming alcohol contributed to a vast number of other serious diseases, including some cancers, heart and liver disease.

People should keep this in mind when thinking about how much they drink.

‘Better effect’

The researchers found that drinking frequency has an independent effect from the amount of alcohol taken.

We can see it’s a better effect to drink the alcohol in four portions rather than all at once.

After around five years, study participants were followed up and a total of 859 men and 887 women group had developed diabetes – either type 1 or the more common type 2.

The researchers concluded that drinking moderately three to four times a week reduced a woman’s risk of diabetes by 32% while it lowered a man’s by 27%, compared with people drinking on less than one day a week.

Red wine is thought to help with the management of blood sugar

Findings also suggest that not all types of alcohol had the same effect.

Wine appeared to be particularly beneficial because polyphenols, particularly in red wine, play a role in helping to manage blood sugar.

When it came to drinking beer, men having one to six beers a week lowered their risk of diabetes by 21%, compared to men who drank less than one beer a week – but there was no impact on women’s risk.

Meanwhile, a high intake of spirits among women seemed to significantly increase their risk of diabetes – but there was no effect in men.

Unlike other studies, this research did not find a link between binge drinking and diabetes.

Prof Tolstrup said this could be down to the small number of participants that reported binge drinking, which was defined as drinking five drinks or more on one occasion.

It is clear that people needed to be wary as the impact of regular alcohol consumption on the risk of type 2 will be different from one person to the next

While the findings were interesting researchers said that they wouldn’t recommend people see them as a green light to drink in excess of the existing NHS guidelines.

That advice suggests that men and women should drink no more than 14 units of alcohol a week – equivalent to six pints of average strength beer or 10 small glasses of low strength wine – over the course of three days or more, with some days being alcohol-free.

‘Not helpful’

It is not helpful to talk about the effect of alcohol consumption on diabetes alone. Consuming alcohol contributes to a vast number of other serious diseases, including some cancers, heart disease and liver disease, so people should keep this in mind when thinking about how much they drink.

Prof Tolstrup and her team have used the same survey to research the effect of alcohol on other conditions.

They found that drinking moderately a few times a week was linked to a lower risk of cardiovascular disorders, such as heart attack and stroke.

But consuming any amount of alcohol increased the risk of developing gastrointestinal diseases, such as alcohol liver disease and pancreatitis.

Alcohol is associated with 50 different conditions, so the researchers are not saying ‘go ahead and drink alcohol’.
