Popcorn is not a vegetable. Due to the fact that it is a kernel that is heated until it pops, popcorn is classified as a grain; this indicates some nutritional value in popcorn.
Consumption of popcorn is calculated along with other grains when balancing food intake based on recommended daily servings of grains. The United States Food and Drug Administration recommends that people consume about 6 ounces of grains per days. This is the equivalent to about 18 cups of popcorn. Popcorn is also very high in healthy antioxidants and fiber, and the American Diabetes Association recommends popcorn as an alternative to starchy snacks for diabetics.
