McDonald's fries have a reputation of using nasty ingredients and unhealthy chemicals. But here's a fun fact: if you look at the nutrition info, they're actually better than KFC's potato wedges! A small portion of McDonald's fries contains 220 calories. A portion of wedges contains 270 calories. You'll find 29 grams of carbs in the fries; 34 in the wedges. And here's the real shocker: a portion of McDonald's fries contains 180 milligrams of sodium. But the KFC wedges contain a grand total of 700 milligrams of sodium.
