34 with microwavable popcorn contains a common food-flavoring substance. This substance, according to health scientists, is 35 for some serious lung diseases.

When the kernels start 38 , shake the pot to let the steam escape and to let the unpopped kernels fall to the bottom. As soon as the popping slows down, 39 the pot from the stove. Then pour the popcorn into a bowl and season with a small 40 of real butter or olive oil and natural salt. And the healthy and fun snack is ready to serve.
