Claim: Pop Zero markets itself as healthy popcorn with under 41 calories per serving and natural ingredients.

What the experts say: "This is a non-GMO product, which is great," says Dr. Marina Yuabova, founder of Integrative Wellness NY. (It's an important fact to remember that most corn in the U.S. is genetically modified.)
