Ever open a bag of microwave popcorn before zapping it? If you do, you’ll find a brick of kernels encased in a chemical cocktail of fats, artificial flavors and colorings, all encased in a nonstick bag that has the chemical bisphenol A (BPA) -- the same toxin being phased out of nonstick cookware. But there’s no need to stop eating freshly popped popcorn. Popping corn on the stovetop is a breeze, and it often involves just a little fat and a pot with a lid. Even loose kernels can be microwave popped: Just place a small amount inside a brown paper bag and microwave for a few minutes. You’ll have hot, fresh and healthy popcorn in no time flat.
