Men’s Journal has named Iowa City the healthiest town in the United States.

The ranking is based on a set of criteria established by Sanjay Gupta, the chief medical correspondent for CNN.

Gupta searched the world for dietary and eating habits, lifestyles, exercise, and personal practices that contribute to a long life for his article titled “The Completely Doable Guide to Living to 100.”

Through his research, he found that there was a relationship between where people live and how long they live. Gupta advised that people should look for a number of things in where they choose to live including local farms, low pollution, sidewalks and good weather.

Boulder, Colo., was ranked second healthiest, followed by Logan, Utah; Northampton, Mass., and Charlottesville, Va.
