There's no doubt that nonstick pans are convenient. But the nonstick coating that makes the pans a cinch to clean up may also be harming your health. For Day 3 of the Healthy Kitchen Makeover Challenge, pull out your old cast-iron skillet and season it. Using cast-iron or stainless steel pots and pans can help you avoid perfluorocarbons (PFCs), chemicals used to coat nonstick pans that are linked to liver damage, developmental problems and cancer. Find out how to season your cast iron skillet here.
