It’s well-established that U.S. adults don’t eat enough fruits and vegetables, and that this contributes to poor health outcomes. But data on how fruit and vegetable consumption affects mortality are limited and inconsistent. It isn’t clear exactly how much produce we should be eating daily to sustain long-term health.
A team led by Dr. Dong D. Wang at Brigham and Women’s Hospital and Harvard Medical School examined the relationship between fruit and vegetable intake and mortality. The researchers gathered data from one study of more than 66,000 women from 1984-2014 and another of more than 42,000 men from 1986-2014. They included participants who were free of diabetes, cardiovascular disease, and cancer when the studies began. Participants answered questions about their diets every two to four years.
