The fast-food chain has been changing its menu to focus on "real" ingredients to win more fans.
The first move in the strategy was a new line of salads such as Apple Pecan Chicken in the summer. Now, the fries, which first appear on Thursday and roll out over the next two weeks. This is the first major overhaul of the 41-year-old company's fries, although it has adjusted the recipe in the past.
The new fries are slightly slimmer than the old ones, and crispier because they're smaller. They will have more salt, a medium size fry goes from 350 milligrams to 500 milligrams, and calories add 10 to 420. The selling price will not change, ranging from 99 cents to about $2. The fries will still come to stores frozen.
Wendy's is planning a marketing push, including national television ads airing later this month, to highlight the changes.
