                                While potatoes, oil, and salt are naturally gluten-free, this fact does not guarantee that every fast-food fry is safe for those with gluten sensitivities. A surprising global discrepancy exists in McDonald's fries, meaning not all McDonald's fries are gluten-free, particularly in the United States, where they contain wheat ingredients.
