Rapid Response:

Does a healthy diet have a be Mediterranean?

The cohort study by Martinez-Gonzalez et al was reviewed at our public health department’s journal club[1]. This raised some issues about the applicability of the findings to a UK population.

The authors assert that the Mediterranean diet is highly palatable, and people are likely to comply with it. In the UK, this diet is expensive and not easily accessible. The authors do acknowledge that the Indian diabetes prevention programme reduced the incidence of diabetes using a plant based diet[2]. So a diabetes- and CHD-preventing diet does not necessarily have to be a Mediterranean diet. In multicultural societies such as the UK, it may be more successful to advise people how they can adjust they’re chosen diet to make it healthier rather than asking them to radically change their eating habits. I assume that the Spanish participants in Martinez-Gonzalez’s study were brought up on a Mediterranean diet. It would be interesting to see how quickly the benefits of the diet emerged if applied to a UK population eating a traditional Western diet.

The results of this study do support a dose-response benefit of eating a healthy diet, including increasing benefits from fruit and vegetables over and above the 5-a-day we are advised to eat.
