Quoted from AFP on Thursday (04/08/2010) research on this topic was conducted by a team from Mount Sinai School of Medicine and published in the Journal of the National Cancer Institute. A total of 470 000 volunteers were involved, were recruited from 10 countries in western Europe.
During the eight years since 1992 scientists investigate and finally concluded that increased intake of fruit and vegetables as much as 200 grams/day only reduced the risk of cancer of approximately 3 percent. From these results, the effects of cancer prevention is considered not as big as expected.
In women, the benefits of smaller fruits and vegetables on cancer prevention. While the people who smoke and drink alcohol, its protection is limited to the risk of smoking-related cancer and alcohol.
"We found that vegetables and fruits provide preventive effects against cancer, but it was not as much as previously thought," said Paolo Boffetta, a doctor who led the research.
This finding is somewhat contrary to the WHO recommendation in 1990, to eating fruits and vegetables at least five times a day. WHO website mentions, 19 percent of gastrointestinal cancers (stomach), 31 percent of ischemic heart disease and 11 percent of strokes caused by a lack of intake of fruits and vegetables.
But the researchers argue that this research team aims to reject the recommendations of WHO. However, consumption of fruit and vegetables still providing benefits for health in general.
