The effect of urea supplementation on the protein nutritional value of a plant protein, opaque-2 corn, for adolescent boys was investigated. Seven 12- to 16-year-old boys were subjects for this 23-day study. The mean apparent nitrogen balance when 6 g of nitrogen from corn was fed and when 4 g of nitrogen from urea was added were + 0.63 and + 1.37 g/day, respectively. The improvement in nitrogen balance resulting from the addition of urea to a plant protein source suggested that urea may be used to partially supply the protein needs of growing boys.
研究了补充尿素对一种植物蛋白——不透明2玉米，对于青春期男孩蛋白质营养价值的影响。七名12至16岁的男孩参与了这项为期23天的研究。当喂食来自玉米的6克氮以及添加4克来自尿素的氮时，平均表观氮平衡分别为+0.63克/天和+1.37克/天。向植物蛋白源中添加尿素导致的氮平衡改善表明，尿素可用于部分满足成长中男孩的蛋白质需求。
