SoS 255: Craving Earth: Pica, Pregnancy, and Nutrition in Malawi with Dr. Leila Larson

This week on The Sausage of Science, Chris and Cristina explore pica (the craving and consumption of nonfood items like earth or clay) through the lens of maternal health and nutrition. Our guest, Dr. Leila Larson of the University of South Carolina, shares insights from her study on pica among pregnant women in Malawi, part of the REVAMP iron supplementation trial. She discusses how iron status, infection, and environment influence maternal health, why intravenous iron may be a more effective approach to reducing pica, and what these cravings reveal about nutrition and development worldwide. We also hear about her new U.S.-based study and how she balances a vibrant global research career. ------------------------------ Find the work discussed in this episode: Larson, Leila M., Martin Mwangi, Rebecca Harding, Ernest Moya, Ricardo Ataíde, Glory Mzembe, Ashley Thurber et al.
