KFC lists a seed oil in 79 of its 120 food items and an artificial additive in 110, with MSG in 63 of them including the marinade on every piece of chicken. The bigger problem is what is missing: KFC discloses its frying oil nowhere, so even Original Recipe's oil-free ingredient statement cannot be taken at face value.
KFC's own ingredient database covers 120 food items and 79 of them list a seed oil, but the true figure is higher because KFC never publishes what it fries in. Original Recipe chicken's entire statement is "Fresh Chicken Marinated With: Salt, Sodium Phosphate and Monosodium Glutamate. Breaded With: Wheat Flour, Salt, Spices, Monosodium Glutamate, Nonfat Milk Solids, Whey, Egg White Solids, Garlic Powder." - no oil at all, for a pressure-fried product. Extra Crispy's breading does name Canola Oil, and Secret Recipe Fries read "Vegetable Oil (Soybean, Canola, Cottonseed, And/Or Sunflower)". Additives are worse: 110 of 120 items, with monosodium glutamate in 63, including the marinade on every piece of chicken. Only eight food items are free of both, and half of those are corn: Corn on the Cob and Sweet Kernel Corn in both sizes, the Caesar and House side salads, Musselman's Applesauce, and the HandHeld Pot Pie, whose whole statement is the placeholder "Handheld Potpie".
