Competitive eating, or speed eating, is a sport in which participants compete against each other to eat large quantities of food, usually in a short time period. Contests are typically eight to ten minutes long, although some competitions can last up to thirty minutes, with the person consuming the most food being declared the winner. Competitive eating is most popular in the United States, Canada, and Japan, where organized professional eating contests often offer prizes, including cash.
