Just a few additional portions of broccoli each week could protect men from prostate cancer. Researchers believe a substance called isothiocyanate in the broccoli sparks hundreds of genetic changes, activating some genes that fight cancer and switching off others that fuel tumors.
Prostate cancer kills more men than any other kind except for lung cancer. Each year, 680,000 men worldwide are diagnosed with the disease and about 220,000 will die from it.
The benefit derived from broccoli would likely also be available from other cruciferous vegetables that contain isothiocyanate, including Brussels sprouts, cauliflower, cabbage, arugula, watercress and horseradish.
