Adventitious mineral elements in Hopi Indian diets
1979
Kuhnlein, Harriet V. | Calloway, D.H.
Extract: Both strontium and lead are geologically present in the Hopi area, but only strontium accumulates in culturally important food plants in the agricultural setting. Lead from natural sources is present in traditional ceramics and culinary ash. In native maize corn foods, iron content was elevated several-fold during home processing. The nutritional environment contains unconventional sources of iron, zinc, manganese and other essential elements.
