Microwave popcorn is a convenient snack made from dried corn kernels that pop when heated in a special bag within a microwave. The bag typically contains kernels, oil or fat for popping, and flavorings like butter or salt. It is a modern, processed version of the ancient snack of popped corn, originating in the United States.
Microwave popcorn is generally high in carbohydrates from the corn and can be high in fat, especially saturated or trans fats from the oil and butter flavoring. A typical serving provides a quick source of energy and some dietary fiber, but can also be high in sodium.

The 'butter' flavor in many microwave popcorns is often created using synthetic flavor compounds like diacetyl, which became a point of cultural discussion regarding artificial ingredients. Nutritionally, the whole grain corn provides a source of polyphenol antioxidants, though this is often overshadowed by added fats and sodium.
