Researchers have found out how broccoli prevents prostate cancer. Sulforaphane, a dietary compound from broccoli helps prevent cancer by working on long, non-coding RNAs. This discovery is a breakthrough in the study of genetics of cancer development. These findings were published by researchers from Oregon State University in the Journal of Nutritional Biochemistry. The research shows that these RNAs, earlier thought to be junk DNA, actually play a crucial role in triggering cells to become malignant.
