Long delays at airports don’t have to mean gorging on unhealthy foods. An increasing number of U.S. airports are now offering relatively healthy food options.

A recent Physicians Committee for Responsible Medicine survey studied 15 of the nation’s busiest airports.

The good news is that 82 percent of the restaurants surveyed offer at least one low-fat, cholesterol-free vegetarian entrée.

However, some airports are much better than others.

Chicago O’Hare, Detroit and San Francisco are the most health conscious.

Delayed in Dallas? Most restaurants offer at least one healthy entrée.

Check out Blue Bamboo Xpress or Cool River Café for options.

If you’re traveling through Washington or Miami, you’ll have to look harder.

But pack your own lunch if you’re passing through Las Vegas.

They were at the bottom of the list for the second year in a row.
