Divergent actress Shailene Woodley admits to eating clay as part of her beauty regime. The former The Secret Life of the American Teenager star found out about the benefits of clay from a taxi driver and claims it to be “one of the best things you can put in your body”.

Talking to Into The Gloss, the 22-year-old said: “Clay is great for you because your body doesn’t absorb it, and it apparently provides a negative charge, so it bonds to negative isotopes. And, this is crazy: it also helps clean heavy metals out of your body.”

However, according to the winner of the MTV Movie Award for Best Breakthrough Performance, you need to be very careful about where you get your dirt from. She believes Mountain Rose Herbs is the best source but admits that Bentonite clay is pretty good too.

The American actress also believes that the best way to whiter teeth is to “swish coconut or sesame oil in your mouth when you wake up and spit it out.”

Might have a go at the teeth thing but not sure about eating clay…
