A study in an upcoming issue of the British Medical Journal showed some components of the Mediterranean diet, such as high vegetable consumption and low meat and meat product consumption, are more significantly associated with low risk of mortality than other components, such as cereal consumption and fish consumption. As part of the European Prospective Investigation into Cancer and Nutrition study, researchers followed more than 23,000 Greek men and women for 8.5 years to see how various aspects of a Mediterranean diet affect mortality. Moderate alcohol consumption, high fruit and nut consumption, and high legume consumption were also associated with lower risk of mortality.
