Five-a-Day May Be Enough for Longevity

the MPR take:

The U.S. Department of Agriculture (USDA) recommends that adults consume 3-5 servings of vegetables and 2-4 servings of fruit per day as part of a healthy diet, but does eating more contribute to additional health benefits? A meta-analysis in BMJ examined 16 studies assessing risk of all cause, cardiovascular, and cancer mortality and fruit and vegetable intake in 833,234 individuals. For each additional serving of fruits and vegetables per day, the risk of all-cause mortality dropped 5% and the risk of cardiovascular disease mortality by 4%; no significant association was observed between higher consumption and cancer mortality risk. Curiously, no greater risk reduction was seen in those consuming over five servings per day, suggesting that five-a-day may be enough for better health and longer life.
