An international study of nearly 500 thousand people have confirmed that eating fruits and vegetables do not prevent cancer. How is the logic?
The results of this study clearly opposed the decision has been made the World Health Organization (WHO) on 20 years ago. World Health Organization has become the benchmark for United States federal government ad that contains an invitation to eat two pieces of fruit and five servings of vegetables a day. In fact, the campaign which was launched five years ago that has cost more than $ 4, 8 million.
However, cancer experts had urged people not to ignore the recommendations of WHO. Section, a high intake of fruits and vegetables is still useful against heart disease and some cancers, like colon and breast cancer, which is associated with obesity.
"We still do not get a clear explanation why fresh fruits and vegetables to reduce cancer, but we know that some types of cancer associated with obesity. Thus, one should maintain a normal weight at that point,''said the chief executive of Cancer Council Australia, Ian Olver.
Furthermore, for eight years, a study conducted by researchers at the European analyze the 478 thousand people. The study found that consumption of approximately 400 grams of fruit and vegetables every day is a simple way to protect against cancer. Thus was obtained from the Sydney Morning Herald, Wednesday (7/4/2010).
Nevertheless, studies published in the Journal of the National Cancer Institute, between 1992 and 2000 found no evidence of a relationship between cancer by eating fruits and vegetables, although a review in 1997 by the World Cancer Research Fund claims to have found convincing evidence.
Bruce Armstrong, a professor of public health at the University of Sydney says that in the study of fruit and vegetables are not focused on any particular type of cancer, but associated with some types of diseases associated with diet or eating patterns.
"Fruit and vegetables clearly has a protective effect against some cancers. So, we do not give the wrong message,''he said.
This result also supports a 2007 study in Australia which found that living in a healthy weight range (ideal) is more important in the prevention of cancer rather than follow the nutrition guidelines.
