We have been using various "natural" peanut butters for years, switching as soon as we learned about the dangers of partially hydrogenated oils. "Natural" is the industry code word for no hydrogenated oils, and we always look for it because even "reduced fat" peanut butters have hydrogenated oils if they're not labeled "natural."  We've tried so many brands over the years, including Skippy which tends to have slightly more saturated fat than other natural blends.
