Calorie Content in Popcorn

A popular snack food, popcorn is a special variety that grows on a cob smaller than those of sweet corn. As the kernels are heated rapidly, the moisture inside them is converted to steam. When the steam pressure builds to a certain point, it bursts the outer shell and the interior turns into a fluffy mass of starch and fibre many times larger than the original kernel. A cup of air- popped plain popcorn has only 30 calories, making it an ideal, high – fibre snack. Popping the corn in oil and adding a tablespoon of butter, however, increases the calorie content more than fivefold, to about 155 per cup.
