抄録

In this study, the dietary patterns in each period from the Middle Jomon period (ca. 4, 000 years before) to the Edo period (ca. 200-250 years before) in Nagano Prefecture, Japan, were reconstructed from δ¹³C, δ¹⁵N, Ba/Ca, and Sr/Ca in excavated human bone samples.<br>In Nagano Prefecture, the prehistoric cultivation of millets in the Middle Jomon Period has been suggested by archaeological evidence. Furthermore, millets are thought to have been one of the major foods for farmers during historical periods. The carbon and nitrogen isotope ratios in excavated bones were measured in order to estimate the importance of C₄ millets in the dietary habits of each period.<br>The carbon isotopic data, did not show us evidence of intensive consumption of C₄ millets in any of the 38 samples dating from the Middle Jomon period too Edo period. In other words, these data cannot suggest either prehistoric millet cultivation or the daily consumption of millets during historical periods.<br>Although Edo samples demonstrated higher δ¹³C values, correspondingly higher δ¹⁵N values made clear that this tendency was not the result of millet consumption but the result of exploitation of more marine nutrition.<br>Furthermore, in one Jomon individual excavated from the Kitamura site, the Ba level was similar to that of wild boar, while the Sr level was lower than those of deer and wild boar. This individual may have lived on low-Sr/Ca plants: pasania and chestnuts are exam-ples within our materials.<br>We conclude that it is possible to reconstruct more detailed palaeodiets and to construct a new model for dietary history using isotope dietary analysis and trace element dietary analysis on same samples.
