America's Healthiest Chain Restaurants: Subway

This is part one of a 10-part series highlighting the healthiest chain restaurants in America, along with the efforts they're making to promote healthy eating. We're defining a chain as any restaurant with more than 15 locations.

Subway has worked hard to promote healthy eating.  They've rolled out chopped salads, offer nine-grain bread as well as flatbread, and have plenty of low-calorie sandwich options. Under its "Fresh Fit" menu, options include sweet onion chicken teriyaki, roast beef, and the Subway Club, all of which contain six grams of fat or less. For the little ones, Fresh Fit Kids' meals come with sliced apples and milk. Salads and Fresh Fit meals have been certified heart-healthy by the American Heart Association.

Subway's website is also a great resource for those looking to eat healthy at the chain. Full nutrition data is available, along with allergy info and a full ingredient guide, and there's even an "Expert Advice" section run by their corporate dietician, full of articles about how to live and eat healthier.
