Hydrogenation is an artificial process, usually resulting in a or some trans fat. Don't confuse it with saturated and unsaturated oils even though they are a related topic. Hydrogenation is a way to artificially increase the saturation of oils.
Many vegetable oils contain some saturated fats among their plentiful unsaturated fats. Those saturated fats are not trans-fats (aka hydrogenated fats).
KFCs problem is that they pressure fry the chicken. That is it is deep fried in a pressure cooker. (every home pressure cooker I've seen explicitly says to not use them to deep fry.)This requires a high smoke point oil and a non foaming oil. That's a difficult combination to achieve without tampering with the oil chemically. Well, more accurately, it costs more to achieve naturally than to do so through hydrogenation.
