In a Cornell University Library Chats in the Stacks book talk presented at Mann Library on November 3, 2011, nutritional scientist Sera Young discusses her new book, "Craving Earth." The urge to eat clay, starch, ice and chalk has been a phenomenon among humans, particularly women, for a very long time. Dr. Young's study seeks to answer why some people engage in this curious behavior , also shedding light on the properties that the non-food substances associated with pica possess.

Hi! Mann Library here responding to your question. As we learn in Dr. Young's presentation, pica is still a rather poorly understood phenomenon, and one unintended consequence of eating clay and earth may be anemia. If you'd like to learn more about Dr. Young's work, you can see a summary at her faculty page on the Cornell University website. Thanks for your interest!

Wait I was confused about the ending. Did she say that eating clay and earth causes anemia or people with anemia crave these items?
