The benefits of buying whole popcorn kernels in bulk vs. store-bought bags are pretty clear. Nutritionally speaking, most commercial popcorn options come with extra additives and unhealthy fats, while whole popcorn kernels are natural and free of refined oils and artificial flavorings. They're also comparably cheaper than buying packaged popcorn and will keep for a very long time in airtight containers. Even better, you can season them with all your favorite spices and *gasp* real melted butter.
