Our article “Pica is prevalent and strongly associated with iron deficiency among Hispanic pregnant women living in the United States” recently published in the journal Appetite. Structured interviews (n=187) were conducted with pregnant Hispanic women living in Salinas Valley, California, during their antenatal care visits; hemoglobin, serum […]
NPR journalist Carolyn Beans recently interviewed Dr. Young about a recent scientific article that documents the geophagic behavior of Amazonian parrots. The authors set out to test the two leading hypotheses about geophagy:
- earth is consumed to protect against toxins in the diet (i.e. secondary plant metabolites)
- during periods of increased nutritional demand, clay is used as a micronutrient supplement
The authors found that for the majority of parrot species observed, clay eating peaked during breeding season and was unrelated to food availability. They interpreted this to indicate that pica among parrots serves as a means of micronutrient supplementation (nutritional demands for sodium increase among birds during breeding periods). Although the study benefits from a large sample size and long data collection period, Dr. Young warned against mistaking correlation with causation. She also argues that clay analysis is needed in order add plausibility to the authors’ conclusions– we still need to know if the clay being consumed is actually high in sodium, and if parrots preferentially choose clays that richer in sodium.
