The HealthSaver Caffeinated Cities Survey found that in terms of overall caffeine consumption habits, Chicago edged out Tampa, Fla., for the top spot on the list, a HealthSaver release said Tuesday.
Miami meanwhile nabbed enough respondent votes to take third place on the list, while the top five most caffeinated cities were rounded off with Phoenix in fourth and Atlanta in fifth.
On the flip side of the list, San Francisco and Oakland, Calif., were tagged with the title of least caffeinated city in the United States.
The two neighboring California cities were followed on the least list by Philadelphia, New York and Detroit respectively.
Olympic gold medalist Peggy Fleming said the survey showed how prevalent caffeine has become in the U.S. culture.
"With the advent of rich, high-end coffees, soaring popularity of energy drinks and national fascination with green tea," the HealthSaver spokeswoman said, "our HealthSaver Caffeinated Cities Survey has brewed up some very interesting trends, findings and results."
