Olestra is a rather unique food additive. It’s an artificial fat substance that can pass through the digestive system without automatically being absorbed, which basically means you can devour a whole bag of chips without having to spend the next four hours on the elliptical machine at the gym. It also has the same general taste as fat, so you don’t lose any of the delicious greasy flavor. This would normally make it a highly desirable substance to add to most foods, if it weren’t for one minor drawback: it may cause “anal leakage”.
Just what does this entail? Your imagination can probably fill in the details, but suffice it to say, it’s probably a good idea to wear Depends if you suddenly get a case of the munchies. Proctor and Gamble (the makers of Olestra) tried to downplay the unexpected stool samples, but the public remained wary. This would not change until 2003, when the company did not get rid of the additive, but rather successfully persuaded the FDA to remove the warning labels from the product. Any bowel movements that you experience these days after eating a whole bag of Fritos is surely just a coincidence.
