The Harris Poll conducted a survey of more than 2,000 U.S. adults. The top answer among 21% of participants was pizza. Coming in at number 2 was steak with 16% of votes. The number 3 spot with 13% of votes went to hamburgers. And 4th place was a tie between tacos and pasta with 11% of votes. Pizza has dominated the survey a few years in a row. The results also indicated that pizza was the preferred "cheat day" food, and participants felt less guilty about eating pizza as long as it included vegetables.
