“…The trace elements strontium and barium, relative to calcium, have also been used, alongside isotopes, to gauge the relative importance of plant versus animal foods in the early human diet. Trace elements have an advantage over isotopes because they are measurable in longer‐lasting bone and tooth tissue; however, concern regarding diagenesis has halted their use (Ungar & Sponheimer, 2013). Balter et al (2012) reported that they overcame this limitation by using laser ablation of tooth enamel.…”

“…Dental microwear analyses study the microscopic patterns of use wear on teeth to infer aspects of food properties and food preparation (Grine, Sponheimer, Ungar, Lee‐Thorp, & Teaford, 2012; Scott et al, 2005; Teaford, 2007; Ungar, 2012; Ungar & Lucas, 2010; Ungar & Sponheimer, 2013). Traditionally, the interpretation of microwear features relied on the material properties of food, falling along a hard versus tough continuum.…”

“…Earlier microwear studies used scanning electron microscopy (SEM); these, however, are costly, time consuming, and have high rates of intraobserver error (Grine, Ungar, & Teaford, 2002). To address these issues, dental microwear texture analysis (DMTA) was developed (Scott et al, 2006; Ungar & Sponheimer, 2013). It uses confocal microscopy to produce a data cloud that represents the occlusal tooth surface, which is then characterized by specific variables calculated through scale sensitive fractal analyses (Scott et al, 2006).…”

“…As a component of the ecological niche that people occupy, diet is a useful lens when studying both present and past human populations. Dietary assessment allows for a comprehensive grasp of human social structures, mobility patterns, activities, and overall health . The methods most often used for the assessment of present diets still rely on dietary reporting (e.g.…”

“…analyses of double labelled water, stable isotope ratios, and gut microbiota) . Methods for assessing past diets are numerous – they include the study of craniomandibular biomechanics, of dental macro‐ and microwear, of coprolites, of microfossils, of stable isotope ratios, of parasite relationships, of gut microbiota, and of genomic adaptations . Clearly, dietary assessment in either of these time frames presents its own set of challenges: present populations are rarely accurate when reporting diet and biochemical approaches can be invasive or laborious, whereas the diet of past populations can only be inferred from proxies, all of which have their limitations.…”
