You have to read the label carefully; even some brands that claim to have 'natural' pb list ingredients like hydrogenated oils and high fructose corn syrup- which, of course, totally defeat the healthy aspects of eating pb. Which I don't really like much, but have on hand as a snack because of its health benefits. Only the ones (store brand or not) that list only peanuts are what I eat.

btw if you ever want to catch a d**n mouse, put some pb out. They love it.
