Mary Rose happened to notice that her latest jar of Jif reduced fat peanut butter spread was a little lighter than usual. No, it was because the jar itself had lost some weight. Two ounces, or 11% of the total contents of the jar, to be exact.

By the way, we go to the effort to say “peanut butter spread” because this product can’t legally be called peanut butter. It doesn’t have enough peanuts, making up the lower-fat difference with “corn syrup solids,” sugar, and pea protein. Mmm, proteiny. It’s about 60% peanuts: actual peanut butter has to be at least 90% peanuts by weight.
