1. Lower Cancer Risk
Onions contain certain organosulfur compounds that give them their distinctive smell, but also work to detoxify the carcinogens that we consume every day. That translates to a lower lifetime risk of cancer. Research suggests that the more onions you eat, the greater the protection.
But before you start an all-onion diet, know that combining onions with turmeric has a synergistic effect, and that garlic offers similar protection. It’s still a great idea to eat onion every day, but you can add these other ingredients to extend the benefits, rather than eat all onions, all the time.
