“Anthocyanin is instrumental in providing color to fruits and vegetables, so it makes sense that the red onions, which are darkest in color, would have the most cancer-fighting power,” Murayyan, the study’s lead author and doctoral student at the university, said in a statement.

Murayyan added, “Onions activate pathways that encourage cancer cells to undergo cell death. They promote an unfavorable environment for cancer cells and they disrupt communication between cancer cells, which inhibits growth.”
