on the box of microwave popcorn it says 3tbs unpopped 170 calories or 1 cup popped 40 calories and that there are 3 servings per bag. Does this mean that a full bag of popped popcorn is 120 calories? i know that's probably a dumb question but oh well.....who eats unpopped popcorn???? if you ate a whole bag of unpopped popcorn it would be 510 calories???? i'm so confused
