The stable isotope composition of mammalian tissues, such as hair, can serve as an indicator of the composition and/or geospatial origin of the diet. Stable isotope analysis has been used to great effect in understanding hominin dietary ecology (Lee-Thorp and Sponheimer, 2006). Additionally, this suite of techniques has been applied to modern human populations, revealing variability in geographic patterns (Ehleringer et al., 2007; Thompson et al., 2010) and other aspects of physiology and health (Fuller et al., 2005; Hatch
