Variant on a American Indian staple, popcorn (with butter and salt) has become intertwined with American fun—state fairs, the circus, sports and movies as well as family spectatorship. The latter includes holiday traditions like making caramel popcorn balls for Halloween (disappearing with concerns for the security of homemade goods) and stringing popcorn to decorate Christmas trees. Microwave popcorn has also been added as a snack in video chains and offices. Popcorn has been touted as a low-calorie, high-fiber food; reports on movie-theater popcorn’s fat and cholesterol in the 1990s, however, forced a change in preparation if not eating.
