try to replace the jiff with natural peanut butter. I know the jiff is pretty damn amazingly excellent, but unfortunately it has hydrogenated oils in it (trans fats). Although the label says no trans fats, if the product has less than one gram, the manufacturer can say 0 trans fat.
I think it's actually below 0.5g, but they just lower the serving size until it's 0.5 or less, then walla, trans-fat free.Wow I did not know that. See, you learn something new every day.
