These delicious golden fries are a simple combination of potatoes, vegetable oil, and sea salt. Wendy's website publishes full nutrition facts and ingredient details for those fries, which includes potassium and fiber figures that are higher than some competitors because the fries keep the potato skin. That "natural-cut" approach (along with the no trans fats and transparent nutrition labeling) is the basis for why many would consider Wendy's the healthiest fast food fries you can buy right now in the U.S., provided you choose portions carefully.
