Dairy Queen
I could not actually find an ingredients list for their french fries. They list nutritional facts, but not ingredients. However, I read something on their main web page that I think is especially funny, "The dietitians at International Dairy Queen, Inc. are registered with the American Dietetic Association. They are available to answer your questions regarding any of DQ's delicious products." I didn't know that fast food restaurants had dietitians!

By definition, a dietitian is, "According to the US Department of Labor, Dictionary of Occupational Titles, one who applies the principles of nutrition to the feeding of individuals and groups; plans menus and special diets; supervises the preparation and serving of meals; instructs in the principles of nutrition as applied to selection of foods." I always thought a dietitian meant someone who promoted the healthiest food options. Boy, was I wrong!
