Isothiocyanates, chemical compounds found in cruciferous vegetables such as broccoli, Brussels sprouts and watercress are able to kill cancer cells that have become resistant to chemotherapy drugs, according to the Free Radical Research Group research team from Christchurch School of Medicine and Health Sciences, University of Otago. Basically, isothiocyanates drive cancer cells, and the protein Bcl-2 that seems to aid cancer cells in surviving, to apoptosis or in more descriptive terms -- a self-destructing suicide. The researchers are hoping this discovery might lead to the development of cancer-fighting drugs derived from isothiocyanates.
In the meantime, as they work on better cancer-fighting drugs based on beneficial chemical compounds found in foods, it won't hurt us to eat more veggies. Okay, except for the current recall of E. coli contaminated spinach. Right now, don't eat your spinach.
While the study suggests that not all cruciferous vegetable are equal in the ability to kill cancer cells, and specifically refers only to broccoli, Brussels sprouts and watercress -- other cruciferous vegetables include arugula, cauliflower, cabbage, Bok Choy, rutabaga, Chinese cabbage, Daikon, radishes, turnips, kohlrabi, kale, and turnip, mustard and collard greens.
