How do they reduce fat in things like peanut butter?

Question

Is there a low fat peanut? Is there a fat removal machine that I need to step into somewhere?

Answer 1

Peanut butter normally has added oil. To reduce the fat, you don’t add the oil. To further reduce the fat, you spin it (in a centrifuge) so the lightest part—the peanuts’ own oil—floats to the top, and then pour it off.
