Chicagoans eat more chocolate and drink more cola than other U.S. urbanites, and are among the top consumers of energy drinks and coffee.

　　They are also likely to say caffeine is good for you, according to the poll conducted by Prince Market Research.

　　Tampa, Miami, Phoenix and Atlanta rounded out the top five most caffeinated cities, while residents of San Francisco, Philadelphia, New York, Detroit and Baltimore consumed the least caffeine.

　　"It's surprising perhaps that some places you may think have a lot of hustle and bustle like San Francisco, Philadelphia and New York, were the least caffeinated cities," said Todd Smith, a spokesman for HealthSaver, a healthcare service that commissioned the poll.

　　The survey looked at consumption of coffee, tea, chocolate, sodas, energy drinks and caffeine pills in 20 major cities in the United States by interviewing 2,000 people.

　　Seattle took the top spot in just caffeinated coffee consumption. Nearly 60 percent of residents in the city said coffee would be the most difficult caffeine product to give up.

　　The growing popularity of "high-end" coffees, energy drinks and green tea has added to more caffeine consumption around the world, according to HealthSaver.

　　Half of all the people questioned in the poll said they drank coffee every day, followed by 21 percent who drank caffeinated cola.

　　New Yorkers and San Franciscans were also among people most likely to say caffeine is bad for you. More than 70 percent of people questioned in the poll said they were not addicted to caffeine. The older the age group the more likely they were to say coffee would be the most difficult caffeinated product to give up.
