The nutritional factors which affect lead absorption have been studied. Synthetic diets of known composition were compounded to contain 0·075% Pb as PbCl labelled with Pb. Rats were exposed to lead for periods of 48 hr. The dietary intake was then measured and the absorption of lead determined by means of a whole-body counter. Lead absorption was increased by high fat, low mineral, low protein and high protein diets but was decreased by high mineral diet. Low fat, low fibre, high fibre, low vitamin and high vitamin diets had no effects on lead absorption.
对影响铅吸收的营养因素进行了研究。配制了已知成分的合成饲料，使其含有0.075%以氯化铅形式存在的铅，该氯化铅用铅进行了标记。将大鼠暴露于铅环境中48小时。然后测量其饮食摄入量，并通过全身计数器测定铅的吸收情况。高脂肪、低矿物质、低蛋白和高蛋白饮食会增加铅的吸收，但高矿物质饮食会降低铅的吸收。低脂、低纤维、高纤维、低维生素和高维生素饮食对铅的吸收没有影响。
