In new research published in Diabetologia scientists report that alcohol drinking frequency is associated with a reduced risk of diabetes and that consumption of alcohol over 3-4 days per week is associated with the lowest risk of diabetes | Science Media Centre
Dr Graham Wheeler, Bayesian Medical Statistician, UCL, said:
“Whilst this large study has found an association between moderate weekly alcohol consumption and a reduced risk of diabetes, this alone does not prove a causal link.
“Establishing a biological mechanism for how this protective effect might work is key to understanding the findings of these types of study.
“In the Danish study, participants were asked to recall drinking habits only once. So participants may under- or over-report their true alcohol consumption. We also don’t know how their drinking habits changed as they were followed up.
“Researchers looked at the association between diabetes onset and lots of different categories of drinking behaviour, which increases the chance of claiming at least one association is statistically significant, when actually it isn’t.
“Whilst drinkers may want to raise a glass upon hearing this news, alcohol has been linked to the increased risk of alcoholic hepatitis, liver cirrhosis and several cancers. Further research will help us piece together the complex relationship between alcohol consumption and diabetes.”
