Banned ingredient: Olestra (aka Olean)
It was the potato chip industry's answer to their high-fat problem. Too bad making a light chip created a bigger problem: spending too much time in the bathroom. To top that off, these fat-free snacks may also make you fat. In a 2011 Purdue University study, rats fed foods containing Olean ate more overall and gained more weight than those fed a high-fat diet including regular, full-fat chips.
Eat instead: Snack on organic chips (non-organic spuds often carry a ton of pesticide residue) that have been cooked in coconut oil instead of GMO vegetable oils such as corn or soybean, a source of inflammatory omega-6 fatty acids, such as Jackson's Honest Potato Chips.
