How to Make Healthier Popcorn?

Some popcorn makers actually use oil to pop the corn, and this can then give popcorn which is actually not that healthy. In this type of popcorn machine the popcorn is higher in calories, and more importantly, up to 45% of the calories in the popcorn comes from fat. If instead you use only hot air to pop the corn, the snack you get is much lower in calories, and only 5% of the calories come from fat.
Plain, air-popped (not microwaved) popcorn is generally agreed to be a good alternative to other snacks like potato chips, candy or cookies. Popcorn is a wholegrain, and provides fiber. Adding butter or oil can increase the level of saturated fat.
As for buckets of popcorn sold in movie theaters, chances are it's loaded with fat, so avoid them.
