国民栄養調査では,鉄,カルシウム,ナトリウムについては,摂取量が発表されているが,微量元素については,発表されていないため,今回,国民栄養調査の結果をもとに,「日本食品無機質成分表」,食品類別荷重平均表を用いて,微量元素のうち, P, K, Mg, Zn, Cuの国民1人1日あたりの摂取量を算出した。算出した結果,1989年では, P: 1205mg, K: 2872mg, Mg: 374mg, Zn: 10.1mg, Cu: 1.41mgとなり,全ての元素において,目標摂取量を上回っていた。

Mineral intakes (P, K, Mg, Zn, Cu) per capita per day were calculated on the basis of the results of the National nutrition survey, using the Weighted average table of minerals in foods from 1960 to 1989. The mean daily phosphorus intake was approximately 1205mg/day. Major contributors of phosphorus were cereals, fishes and shellfishes, and milk and daily products. The mean potassium intake was 2872mg/day. The richest source was vegetables followed by fishes and shellfishes. Magnesium intake was 374mg/day, and zinc was 10.0mg/day. Main sources of them were plant products, especially cereals. The daily intake of copper was 1.41mg/day. The usual foods sources were cereals, fishes and shellfishes, and pulses. These mineral intakes were sufficient for their adequate dietary intakes.
