Abstract

現在市販されている22種類の経腸栄養剤のセレン含量を蛍光光度法で測定した. セレン含量はおのおのの経腸栄養剤により, 0.04~5.74μg/100kcalと大きな差異を認めた。卵白を加えた経腸栄養剤が牛乳タンパクのものよりも比較的セレン含量が高く, また, アミノ酸に分解した成分栄養剤は低値であった。これらの経腸栄養剤のみで必要エネルギーを得るとすると3.2~146.4μg/日となり, 米国における推奨栄養所要量 (RDA) 0.87μg/kg/日の約50%しかセレンを摂取できない経腸栄養剤が大部分で, なかにはRDAの1割以下しか摂取できないものが見られた。経腸栄養剤によるセレン欠乏症を予防するために, セレン含量の低値の経腸栄養剤に対してセレンの添加が考慮されるべきである。

We measured the selenium content of Japanese enteral formulas using a fluorimetric procedure. The amount of selenium present in these formulas varied widely, the highest amounts (2.77-5.74μg/100kcal) were found in egg albumin-based diets. Casein-based formulas contained intermediate amounts (0.45-1.88μg/100kcal) whilst the chemically defined formulas contained the lowest amounts (0.04-0.58μg/100kcal). Based on an average caloric ingestion in adult women of 2, 000 kcal/day, or 2, 550 kcal/day, in adult men, we calculated that women would receive 3.2-114.8μg/day of selenium, and men 4.1-146.4μg/day, depending on the formula prescribed. Sixteen of the 22 formulas analyzed contained levels of selenium, which would fall below the USA recommended dietary allowances (RDA). Selenium supplementation should therefore be considered for these formulas.
