Outline of Final Research Achievements

By examining the diversity of foods consumed by humans in the past and changes over time, we can understand the link between livelihoods and economies and dietary habits, and the impact of dietary habits on health. In this study, DNA was extracted from a total of more than 100 modern and ancient dental calculus and aligned to a comprehensive database of plants, animals, bacteria and viruses. The results showed that shotgun sequencing detected very little non-human animal and plant DNA, indicating the need for enrichment of animal and plant DNA. On the other hand, it was found that an old clade unique to Japan existed in oral bacteria commonly found in ancient dental calculus and was passed down to the Edo period. Nitrogen carbon stable isotope analysis of bones and teeth, as well as dentin proteomic analysis, were also carried out and the results reported as papers.
