Madrid: A Mediterranean diet that includes fruit, vegetables, fibre and healthier fats may protect against type two diabetes, a new study suggests.

The study monitored the eating habits of 14,000 Spaniards over a four year period to see who developed the condition.

The results indicated a 83% lower risk for those who followed the diet, the British Medical Journal reported.

The traditional lifestyle of the Mediterrean includes regular exercise, but also plenty of fish, fruit and vegetables, usually cooked in olive oil, and red wine.

This diet has already been shown to be good for heart health. In addition olive oil helps control blood sugar and lower blood pressure.
