Broccoli Can Protect You from Bladder Cancer

broccoliprotectcancer.jpgVegetable lovers would be happy to hear that their favorite broccoli can protect them from bladder cancer.

According to Dr. Yuesheng Zhang, professor of oncology at Roswell Park Cancer Institute, eating cruciferous vegetables like broccoli can reduce the risk of bladder cancer in humans. This claim is based on their study using laboratory animals. The rats were given different doses of broccoli sprouts extracts then given a chemical that can induce cancer. The number of animals who developed cancer is lesser among those who were given high doses of broccoli sprouts extracts compared those with lesser dosage and those without broccoli extracts.

Apparently, cruciferous vegetables like broccoli contain a phytochemical called isothyiocyanates (ITCs) which can prevent cancer. Mature broccoli, cabbage, kale, collard greens and other cruciferous vegetables also contain ITCs but broccoli sprouts have approximately 30 times more ITCs than mature broccoli.

Although, the dosage of broccoli extracts used in the experiment is very high, Zhang said humans do not need to eat huge amounts of broccoli sprouts in order to get its protective benefits. Previous research have already shown that eating cruciferous vegetable may reduce the risk of bladder cancer in humans, thus, it is possible that lower dosage of ITC may be enough to prevent bladder cancer.

The study was funded by the Vital Vegetables Research Program of Australia and New Zealand, the National Cancer Institute and the Roswell Park Alliance Foundation.
