High Adherence to Mediterranean Diet May Reduce Diabetes Risk

Adults who closely follow a Mediterranean diet may be less likely to develop type 2 diabetes, according to a prospective observational study published online in BMJ.

Nearly 14,000 Spanish university graduates (mean age, 38) without diabetes completed food-frequency questionnaires and were then followed for roughly 4 years. During that time, 33 cases of new-onset type 2 diabetes were confirmed. After adjustment for known diabetes risk factors, participants with high adherence to a Mediterranean diet were 83% less likely to develop diabetes, and those with moderate adherence were 60% less likely, relative to those with low adherence.

These results indicate that a Mediterranean diet can offer “substantial protection against diabetes,” the authors write. However, given the small number of diabetes cases and the possibility of underreporting, they call for larger trials to confirm their findings.
