Skippy and "natural" are more similar than different.
Hydrogenated fats do NOT equal trans fats. Only partially-hydrogenated oils become trans fats. Fully hydrogenated ones -- like in Skippy -- become saturated fat. Peanuts and other nuts already contain saturated fat, so it's only a matter of quantity. Looking on the jars of Skippy and of "natural" Laura Scudder's, the Skippy has 16 gm total fat, 0 trans fat, and 3 gm saturated fat vs. Laura Scudder's 16 gm total fat, 0 trans fat, and 2.5 gm saturated fat. Yes, the Skippy has added sugar. If you don't like that, choose the natural kind. But with 3 gm saturated fat in Skippy's vs. 2.5 gm saturated fat in the natural kind, I don't see how there's a great, or even significant, nutritional difference. (Plain peanuts in a can have 2 gm of saturated fat, just fyi.)
