They're cut with a knife. Some people believe that the perfectly straight fries are made using molds and fake potato goop. But since the fries are made with real potatoes, they are cut with a real knife. After the potatoes are skinned and washed, they are shot through a series of blades that cut them into French fries.
A serving of the fries does contain a large amount of saturated fat and sodium, which decreases their nutritional value significantly. Too much saturated fat and sodium can lead to heart attack, stroke, kidney disease and high cholesterol. A small order of fries contains 15 grams of fat and 480 milligrams of sodium.
