Few will argue against including more fruits and vegetables into your diet, but new research says getting the recommended "five a day" may not have a big effect on cancer.
A study in the "Journal of the National Cancer Institute" says for every two extra portions consumed the risk of cancer is reduced by less than 3 percent.
The study of 500,000 Europeans joins a growing body of evidence undermining the high hopes that five portions of fruits and vegetables a day might slash cancer rates.
Experts stress that even if they just take the place of other less healthy foods, fruits and vegetables are still key to good health.
