Is popcorn healthy?

Whether popcorn is “healthy” depends how you eat it. In its purest form — that is, plain air-popped kernels — it’s a healthy, whole-grain, antioxidant-rich snack food that comes at a pretty low-calorie cost for those who like to mindlessly nibble: A three-cup serving of air-popped popcorn has only 93 calories, 1 gram of fat and close to 4 grams of fiber.
