I get the Arrowhead Mills 100% Peanut Butter. No added sugar, fats, or salt. Also, it's a natural one, so the oil separates - I just pour off as much of the oil as possible. Of course, it's 'crunchy' and you can't get the oil out of the solid peanut pieces, but I feel better about pouring off as much oil as I can. I find that without the sugar and salt, it tastes (sorry Jif) more peanutty than the others. Now that this is the only brand I use, I can't stand the regular ones - they don't taste like peanuts, just a salty blob.
