Fruit and Vegetable Consumption Could Lead to Longer Life

A team of U.S. researchers has found an inverse association between fruit and vegetable intake and mortality in two large prospective cohorts, the Nurses’ Health Study (NHS) and the Health Professionals Follow-up Study (HPFS), with detailed and repeated dietary measurements and long follow-up; the lowest risk of mortality was observed for approximately five daily servings of fruits and vegetables, eaten as two servings of fruit and three servings of vegetables, but above that level, the risk did not decrease further;

an updated meta-analysis of 26 prospective cohort studies including the NHS and HPFS yielded similar results; the findings support current U.S. dietary recommendations to eat more fruits and vegetables and the simple public health message ‘5-a-day.’

Diets rich in fruits and vegetables help reduce risk for numerous chronic health conditions that are leading causes of death, including cardiovascular disease and cancer.

Despite recommendations in dietary guidelines to increase fruit and vegetable intake, 3-5 the current average intake among U.S. adults, 1 serving of fruit and 1.5 servings of vegetables per day, remains far from optimal.
