No health benefits beyond eating 5 servings of fruits, veggies daily

August 15, 2014

A study published in the British Medical Journal shows that eating five daily servings of fruits and vegetables may significantly lower the risk of death, but eating more than that doesn’t appear to provide additional health benefits.

In a meta-analysis of 16 studies involving more than 833,000 participants, the researchers found that each daily serving of fruits or vegetables was associated with a 5% lower risk of mortality, so that eating five servings a day lowered the risk by 25%. But eating more than that didn’t lower the risk further. Senior author Frank Hu, Professor of Nutrition and Epidemiology at the Harvard School of Public Health hypothesizes that it is possible the human body may only be able to process a certain amount of fruits and vegetables each day, and that the availability of nutrients and other bioactive compounds of these foods may have reached a plateau at five servings per day for most people.
