Study looks for diet/heart disease link

A study has identified a mechanism by which the Mediterranean diet prevents the development of coronary heart disease (CHD).

The latest results of the long-term Predimed study – supported by the Spanish Health Ministry – have found that a diet rich in fruit and vegetables can decrease the oxidative damage to LDL cholesterol, exerting a protective mechanism that deters the development of CHD.

A feeding trial in a population at high risk of CHD development compared two Mediterranean diets – one supplemented with nuts and the other with olive oil – with a low-fat diet.

After the three-month intervention period, a diet high in fruit and vegetables and supplemented with olive oil or nuts reduced blood lipids, arterial pressure, fasting blood glucose and inflammation – all risk factors for heart disease.

According to the results, while both olive oil and walnut-supplemented diets had a positive effect on blood lipids, triglycerides were only reduced in the group that ate walnuts.

The Predimed study is a multi-centre, randomised, single-blinded trial which attempts to assess risk factors for CHD by comparing two intensive behavioural counselling and nutrition education groups with a control group.
