                                Three cups of plain, air-popped popcorn contain approximately 0 grams of sugar, according to WebMD. This makes unseasoned air popcorn a naturally sugar-free snack, distinguishing it from many pre-packaged or movie theater varieties that are loaded with added sweeteners and flavorings.
