1. Fat-Free Chips – USA
Let’s start with something that sounds like it should be healthy: fat-free chips. These chips, specifically those made with Olestra, were the snack of the late 90s and early 2000s. Olestra, a fat substitute, was meant to allow guilt-free munching, but it came with some unexpected side effects. People reported severe digestive issues like cramps and diarrhea, earning Olestra the nickname “anal leakage.” The backlash was so intense that products containing Olestra were pulled from many shelves. While it’s not officially banned, its use is rare due to its notorious reputation.
