Microwavable popcorn
Microwavable popcorn is chock full of salt, preservatives, and fat. The same goes for the movie theater popcorn, which personal trainers never eat. The healthiest way to enjoy popcorn, which is naturally high in fiber, is to air pop your own kernels. Even popping them over a stove with minimal oil and salt is a better option than a packaged microwavable bag.
