Here’s Why Scientists Say Eating Boogers Could Be Good For You

Come again?

Parents are always telling kids not to pick their nose, and especially not to, ahem, eat their findings. “It’s gross,” we discourage. “You’re going to get sick!”

Well, that may not actually be true. In fact, research actually says otherwise: That eating your boogers could help to keep you healthy.

Yep, it sounds crazy, but it’s true: Research has found that there is bacteria in our boogers that is actually good for our oral hygiene. Um, ew? And also, huh?

No, really. Scientists have found that the “salivary mucins” in our mucus can help to protect our teeth from developing cavities. And oral health is a crucial cornerstone of overall health.

Studies have shown a link between gum disease and heart disease. And daily flossing is said to have a positive impact on your life expectancy. So apparently, along with regular flossing and brushing, booger-eating may be part of a healthy oral hygiene program.

One scientist has even said that boogers could help boost the body’s overall immunity. The idea falls into the “hygiene hypothesis,” which posits that exposure to germs and certain infections at a young age could actually help build a child’s immune system.

“From an evolutionary perspective, we evolved under very dirty conditions and maybe this desire to keep our environment and our behaviors sterile isn’t actually working to our advantage,” the scientists behind the booger-immunity theory told CBC News.
