No benefit to eating more than five daily servings of produce, study suggests

The Boston Globe reports:

The US government recommends that American adults eat 5 to 13 servings of fruits and vegetables depending on your age, gender, and activity level, but a new Harvard School of Public Health study suggests we don’t get additional health benefits if we eat more than five servings a day.

After analyzing 16 studies involving 833,000 participants who filled out dietary surveys, the researchers from Harvard and China discovered that each daily serving of produce was associated with a 5 percent lower risk of dying from heart disease or cancer during the studies, which lasted up to 25 years. Eating five servings a day, for example, lowered the risk of dying by 25 percent — but so did eating six or seven servings, according to the results published last Tuesday in the British Medical Journal.
