Fruit and vegetables could have a protective effect against disease as they contained antioxidants, which repair damage to cells, she said.geijlsngi15

Experts said the work was not conclusive and that other lifestyle factors may have influenced the results.

Prof Tom Sanders, at the School of Medicine, King's College London, said it was "already known" that people who said they ate lots of fruit and vegetables were health conscious, educated and better-off, which could account for the drop in risk.

"You cannot extrapolate from this kind of information to make sensible pronouncements about what people should eat."

Prof Naveed Sattar, of the University of Glasgow, said promoting a seven-a-day message would be "really challenging".

"It would require governmental support such as subsidising the cost of fruit and vegetables, perhaps by taxing sugar-rich foods, and making available high quality products to all in society," he said.

A spokeswoman for Public Health England said it "welcomes this new research, which supports existing evidence showing the health benefits of consuming fruit and vegetables".

But she added about 66% of adults did not eat five a day and some only ate one.

She said the organisation would focus on increasing the "overall" consumption of fruit and veg to cut the risk of disease.

Victoria Taylor, senior dietician at the British Heart Foundation, said people were still struggling to meet the existing target of at least five a day.

"While you may not be getting your five a day, there's no reason to give up and stop trying as this study showed there were health benefits for every extra portion of fruit and veg people ate," she said.

In Australia, the government's advice is "two plus five" a day - encouraging people to eat two helpings of fruit and five portions of vegetables.异乡为一客 雨季的春天歷程之路very delicions！ kioewpreEyes do speak飞羽之恋 蒙语思思
