Pregnant women love eating rocks.

This is pretty wacky, but then again I secretly love Taco Bell.

From BBC:

Researchers from the University of Nigeria interviewed 1,071 pregnant women attending a prenatal clinic at the Pumwani Maternity Hospital in Nairobi.

At least 800 of those interviewed said they ate soil, stones and other non-food items during their pregnancy.

But it is not only those who are pregnant who indulge in this habit.

Sylvia Moi still finds the soft stones irresistible, 14 years after she gave birth.

"I cannot do without it... Walking without it makes me feel bad, as if I'm lacking something [or] I'm hungry," Mrs Moi says.
