Broccoli to the defence
JUST a few more portions of broccoli each week may protect men from prostate cancer, British researchers reported.The researchers believe a chemical in the food sparks hundreds of genetic changes, activating some ge
nes that fight cancer and switching off others that fuel tumours, said Richard Mithen, a biologist at Britain’s Institute of Food Research.
There is plenty of evidence linking a healthy diet rich in fruits and vegetables to reduce cancer risk. But the study published in the Public Library of Science journal, PLoS One, is the first human trial investigating
the potential biological mechanism at work, Mithen added in a telephone interview.
“Everybody says eat your vegetables but nobody can tell us why,” said Mithen, who led the study. “Our study shows why vegetables are good.”
Prostate is the second leading cancer killer of men after lung cancer. Each year, some 680,000 men worldwide are diagnosed with the disease and about 220,000 will die from it.
