Lay's WOW

Lay's WOW was a late-1990s snack miracle: fat-free potato chips that tried to keep the experience of eating chips by replacing fat with Olestra, a fat substitute the body mostly declined to absorb.

The catch was printed on the bag. For years, olestra products carried an FDA-required notice that they might cause abdominal cramping and loose stools, which is a lot of informed consent to ask from a potato chip.

After the FDA dropped the warning requirement, Frito-Lay renamed the line Light. The tote survives from the brief period when the boldest promise in American snacking was: all the chip, none of the fat, please read the gastrointestinal appendix.
