Why take a pill when you can find what you need in "real" food ?
Taking supplements of lycopene, the tomato-derived carotenoid making growing sales in the supplement market, may not be sufficient to fight against the onset of prostate cancer, say researchers in a new study.
The antioxidant, also responsible for the red colour of tomatoes and other fruits, has been linked to reduced risk of prostate cancer in studies. It is marketed increasingly in supplement form but the new findings, based on a comprehensive prostate-cancer survival study done on rats, found that it may be more powerful in combination with other phytochemicals in tomatoes.
"It has been unclear whether lycopene itself is protective. This study suggests that lycopene is one factor involved in reducing the risk of prostate cancer," said John Erdman, professor of food science and human nutrition and of internal medicine at the University of Illinois, US.
"This also suggests that taking lycopene as a dietary supplement is not as effective as eating whole tomatoes. We believe people should consume whole tomato products - in pastas, in salads, in tomato juice and even on pizza."
