Mediterranean diet beats diabetes even without weight loss

A diet rich in fish, fruit, vegetables and whole grains may help at-risk people stave off diabetes even if they don’t manage to shed the pounds, say Spanish researchers.

Their study randomised 3,500 people without diabetes but at high risk of cardiovascular disease to one of three diets: a traditional Mediterranean diet with added extra-virgin olive oil; the Mediterranean diet with added nuts; or a control low-fat diet.

They found those on the Mediterranean diet with olive oil were around 40% less likely to develop diabetes over four years
