That rings a bell... I've definitely heard that before. Makes good sense, too!

Geologists sometimes taste-differentiate minerals (NaCl / Sylvite, etc) and
probably more often rely on textural tests, although it isn't so much the tongue
that is used, as it is placing a bit of material between the upper and lower
front teeth, pressing them together and moving them back and forth--pure clay is
smooth, and there is a different textural feel for silt and sand.
There is a clay (advertised) toothpaste (Umbrian Clay?). A few years ago I
spoke to the author of a journal article, "Geophagy in a Mississippi
County" and he spoke of (as I remember) human consumption of clay as
much as two - four ounces a day there, mainly in infants and young women.
