The Food Fix: Eat Your Onions
Battling breakouts? The antioxidants in onions and other sulfur-rich veggies tamp down the inflammation that leads to acne, says Valori Treloar, M.D., a dermatologist in Newton, Mass., and co-author of The Clear Skin Diet. The sulfur in onions, leeks and scallions helps produce a detoxifying molecule called glutathione, which a 2011 study found to be lower in the skin of people who were prone to breakouts.

This antioxidant is most potent when eaten in raw or lightly cooked foods. Try adding chopped scallions to your salad or stirring diced onions into your salsa or stir-fry. Taking folate and vitamin B6 and B12 supplements may also boost glutathione levels.
