Non-natural peanut butters sneak in more than peanuts and salt. Sugar is listed as the second ingredient in some popular brands of peanut butter that also contain molasses (another sweetener). Two tablespoons of these products can contain 3g of sugar. Sure, it’s not a lot, but who needs sugar in peanut butter? Choose a natural peanut butter instead. They can taste just as good, if not better, without the added sugar.
