Context

The incidence of type 2 diabetes is increasing and has been associated with the Westernisation of dietary habits. The Mediterranean dietary pattern (Med diet) may be a way to reduce the incidence of type 2 diabetes. In a trial, it was shown to reduce the need for antidiabetic drugs in diabetic patients,1 and an epidemiological study suggested a lower incidence of diabetes with increasing adherence to the Med diet.2 However, its role in the prevention of diabetes has not been investigated so far in a randomised trial.
