Popcorn is divisive. It’s a great alternative for someone trying to quit potato chips and Cheetos, but it’s still not exactly health food. The thing is, though, it’s packed with fiber and polyphenols, which Shape points out are antioxidants that can protect against heart disease and certain cancers. In fact, research shows that popcorn has the highest polyphenol levels of all snack foods. If you can manage it, pop straight corn kernels instead of packaged movie theater popcorn. For a healthy, cheesy kick, sprinkle on nutritional yeast and get an extra boost of vitamin B12.
