This week's lucky "winner"... kettle corn!
Who doesn't like kettle corn, that sweet, crunchy treat? And why not indulge-- it's just a whole grain with a little bit of sugar!
It's certainly all right to eat kettle corn from time to time, but there is a reason we find it so seductive. Although it may appear light and fluffy, popcorn is actually quite calorie-dense. This is because chewing expels the air in popcorn, leaving a small volume in the stomach that's not much greater than if you had simply eaten unpopped kernels. This means that popcorn, like crackers and rice cakes, doesn't deliver very much satiety for the number of calories it contains, at least compared to water-rich foods like potatoes.
Calorie density is also one of the primary rewarding properties of food, which is one of the main reasons why we like popcorn so much. Add a coating of sugar to it, or fake butter in the case of movie popcorn, and it becomes easy to overindulge.
