Jen, I can't get the ingredient list to come up online, but a post I found on a website (
http://msnbc.msn.com/id/7804202/ ) noted that the Skippy Natural contains palm oil. That stuff is horrible for you...full of saturated fat and likely to clog your arteries.
They include it, I assume, so they can say that you don't have to mix their natural PB. Don't eat this stuff, hon. Go with a truly natural PB--the only ingredients should be peanuts and possibly salt. If you mix the PB at the beginning, then put it in the fridge, you won't have to mix it again. The oils in the Natural PB (the real stuff, not the Skippy) are actually beneficial for your health, while the palm oil is detrimental. Take care of yourself, okay?
