Olestra, aka Olean, created by Procter & Gamble, is a calorie- and cholesterol-free fat substitute used in fat-free snacks like chips and French fries. Three years ago, Time Magazine3 named it one of the worst 50 inventions ever, but that hasn’t stopped food companies from using it to satisfy people’s mistaken belief that a fat-free snack is a healthier snack. According to the featured article: “Not only did a 2011 study from Purdue University conclude rats fed potato chips made with Olean gained weight, there have been several reports of adverse intestinal reactions to the fake fat including diarrhea, cramps and leaky bowels. And because it interferes with the absorption of fat soluble vitamins such as A, D, E and K, the FDA requires these vitamins be added to any product made with Olean or olestra.” Where it’s banned: The UK and Canada
