Abstract

There is a bidirectional interaction across nutrition, infection and immunity. While good nutrition increases the immune system's response, immune deficits following malnutrition early in life have been shown to persist for weeks and even years. This study combines osteological and archaeometric analysis providing significant novel perspectives on the synergy between diet and health exploring stable isotope analysis. It is intended to assess whether stable isotope analysis can be used as a tool to study the impact of diet on the individuals' susceptibility to pathogens. This study will help understanding the physiological mechanisms of stress and disease prior to the advent of modern medicine and antibiotics, as well as improve dietary isotope data interpretation.

The diet at Tomar was complex (δ13C=-18.6±0.5‰, δ15N=10.8±0.8‰, δ34S=13.1±1.5‰), low in terrestrial animal protein and high in aquatic protein intake, despite its inland location. No statistically significant differences (p>0.05) were found between sexes or socio-economic status. δ15N differed significantly between skeletons with non-specific generalised infections (δ13C=-18.7±0.8‰, δ15N=9.9±0.4‰) and those with only healed tibial periosteal reactions (p
