^ Skippy, Peter Pan, and Jif are not completely trans fat-free. Look in the ingredients list for the phrase "partially hydrogenated"...that's the oil which keeps those peanut butters homogenous, and those are trans fats. In the United States, they're allowed to label their products as "zero trans fat" if there is less than a half-gram of trans fat per serving size indicated on the nutritional label.
Pretty sneaky, no?
We have four opened jars of peanut butter at home, to suit any mood. Lily's, creamy Peter Pan, crunchy Pan de Manila, and a crunchy organic Canadian brand. All bases covered.
