It has few calories—if you pop it the right way
When we talk about the benefits of eating popcorn, we’re talking about air-popped popcorn, not the fatty, butter-drenched stuff you get at the movies. The Center for Science in the Public Interest found that the medium and large popcorn sizes at Regal theaters each had 1,200 calories and 60 grams of saturated fat. A large popcorn at AMC wasn’t much better: 1,030 calories and 57 grams of saturated fat. The healthiest type of popcorn is air-popped, which only has 30 calories. You can use a hot air popper or try this hack: Put 3-4 tablespoons of kernels in a brown paper bag, fold the top of the bag twice to make sure it’s closed, and then microwave for two minutes, or until there are only a few seconds between pops.
