Fruit and veg: More than five-a-day 'no effect'

New research backs the five-a-day target for fruit and vegetables, but suggests eating more may have no added benefits.

An analysis of 16 worldwide studies suggested that for every portion (80g) of fruit and vegetables consumed, there was a lower risk of premature death.

But after five portions a day, there was no further impact, researchers report in The BMJ.

The new analysis looked at 16 studies in the US, Asia and Europe involving more than 833,000 people, of whom about 56,000 died during the follow-up period.

Researchers in the US and China found eating more fruit and vegetables was linked with a lower risk of dying from any cause, particularly from cardiovascular disease.

The average risk of death fell by about 5% for every extra serving of fruit and vegetables, up to five servings a day, but not beyond.
