7 Grossest Things In Your Food

Why your cheese isn’t vegetarian—and 6 other shockers

3. Sheep Oil In Your Gum

Not to burst your bubble, but there might be something rather unsavory in your chewing gum. It’s called lanolin, a term for the oil sheep produce in their wool. These greasy secretions are used as softeners in foods and masked with the vague food label “gum base.”  Lanolin is also used as an emollient in beauty products, from skin and hair care to cosmetics.

How to avoid it: Luckily, there are vegan versions of all of these products. If you’re concerned about eating lanolin, go for those, instead.
