与陆地比率相比，海水中的钡与锶的比率极低。在海洋物种和以海洋资源为生的史前人群的骨骼成分中也发现了较低的 Ba/Sr 比率。因此，人体骨骼中 Ba/Sr 比率的差异可以用来衡量饮食中海洋和陆地成分的相对含量。书中还介绍了一些警示故事。
Seawater has an extremely low ratio of barium to strontium in comparison to terrestrial ratios. Low Ba/Sr ratios are also found in marine species and in the bone compositions of prehistoric populations who subsisted on marine resources. Differences in the Ba/Sr ratios of human bones can thus be used as a measure of the relative amounts of marine and terrestrial components of diet. Some cautionary tales are also presented.
