Could Double-Dipping Bring About Health Dangers?

Are you disgusted by etiquette-killing eating habits that make your stomach churn?

“It’s in our everyday life,” says Valerie Curtis, a professor at the London School of Hygiene and Tropical Medicine. “It determines our hygiene behaviors. It determines how close we get to people. It determines who we’re going to kiss, who we’re going to mate with, who we’re going to sit next to.”

Fortunately, the disgust you feel when viewing a food transgression has a biological purpose– that churning in your stomach helps keep you safe from health problems associated with things like disease and parasites.

But the chasm between what grosses you out and what is actually harmful to you is probably larger than you realize. Many things that get you feeling green are, in fact, harmless.

Regardless, perhaps there is no eating behavior more apt to repel your sensibilities than the double dip. Find out why, on the other side of the spectrum, it might not be as harmless as you think.

Don’t Do The Double

The depressing truth about your dip is that it’s already swimming with bacteria — though you usually are able to make it out of festive parties and events involving food with your GI tract still functioning just fine. However, according to an investigation conducted by the Mythbusters team on the Discovery channel, the act of dipping two times adds an unhealthy amount of microbes to your body.

Adam Savage and Jamie Hyneman of the TV show evaluated bacterial growth in a controlled lab environment by dipping clean chips into sterilized salsa. What they came to realize was that “double-dipped” chips offered anywhere between one and four bacterial colonies to the salsa in two samples– and amounts of salsa that were placed in their mouths and returned to the dish had many, many more.
