The 'Recipe Doctor' rates the best and worst fast-food fries.

There's no doubt: french fries are one of America's favorite foods. French-fried potatoes are the featured side dish at nearly all fast-food chains, and at many sit-down restaurants as well. And the selection of types of frozen french fries at your typical supermarket is mind boggling.

French fries are thought to have originated in 19th century Belgium, spreading later into France and later still into the greater part of the Western world. But you can credit American fast-food chains for making french fries a fixture in casual cuisine.

Of course, french fries are by nature pretty high in calories and fat. We are talking about deep-fried potato strips, after all. But in the wonderful world of fast-food fries, there's a big difference in how much calories, fat, and "bad fats" (saturated and trans) you'll find in a serving of french fries, based on where you buy them.

Nutritionally speaking, who makes the best and worst french fries? To find out, we compared calories, fat grams, "bad fat" grams, percentage of calories from fat, and sodium levels for the "small" or "regular" serving of french fries at 14 major fast-food chains. The serving sizes for these fries ranged from 75 grams to 125 grams, so this is also a case where size matters.

The 14 fast-food chains we looked at were:

  • Arby's
  • Burger King
  • Carl's Jr.
  • Chick-fil-A
  • Dairy Queen
  • Hardee's
  • In & Out
  • Jack in the Box
  • KFC
  • Long John Silvers
  • McDonald's
  • Sonic Drive-In
  • Wendy's
  • White Castle
