Snackwell's was a brand of Nabisco products. Introduced in 1992, its products include cookies of a variety of flavors including creme, shortbread, and devil's food cake.
Snackwells were marketed as a fat-free and thus healthier snack, as the U.S. dietary guidelines of the early 1990s advocated a reduction in the consumption of fats. In an ironic and unintended consequence, Snackwells' higher carbohydrate count was later cited as a likely contributor to the obesity epidemic of the 1990s and beyond.
The Snackwell Effect was named for the tendency to consume greater quantities of an item or service deemed morally superior, such as a putatively healthier cookie, or more energy-efficient lighting.
Snackwells were developed by Nabisco's principal food scientist, Sam Porcello.
Snackwell branded products are now made by Back to Nature Foods in Naples Florida. In Canada, SnackWell's potato chips and crackers are available.
