Onions Fight Cancer
Grab your breath mints! Consuming onions is good for your health; and the stinkier, the better.
While it may sound humorous, onions are thought to be good cancer fighters, and now study leader Rui Hai Liu and colleagues have shown that amongst onions, those with the strongest flavor have the highest antioxidant activity and are best for inhibiting the growth of liver and colon cancer cells.
Onions are rich in a flavonoid called quercetin that's a potent antioxidant.
Overall, onions were far better at inhibiting the growth of colon cancer cells than liver cancer cells, suggesting that they're better colon cancer fighters.
As for cooked onions, the researchers didn't test whether cooking affects their cancer-fighting ability.
