white clay

There's apparently a village in China where some of the inhabitants like to eat 白土. As far as I can tell, it's a type of white clay.

I just caught an interesting Japanese program on it, where they sent a girl to stay with a family where the mother loves the stuff, and the father doesn't eat it at all, but he digs it up for the mother.

They showed the family painting the walls with it, as a whitewash. And the mother tasted the brush and said it was delicious. Hilarious. She couldn't stop licking the brush.

The U.S. has some crap tv. Although there are some good shows, there's really a shocking amount of junk.
