稳定性同位素示踪技术用于研究体内矿物质的吸收和代谢始于1963年[1],其优越性在于灵敏度高;可在正常生理条件下进行;实验操作简单;试验期较短等,亦可用于高风险人群代谢组学的研究,如婴儿、儿童、孕妇以及哺乳期妇女,因此 Stable isotope tracing technology used to study the absorption and metabolism of minerals in the body began in 1963 [1], its superiority is high sensitivity; can be carried out under normal physiological conditions; experimental operation is simple; the test period is short etc. It can be used for metabolomics research in high-risk groups such as infants, children, pregnant women and lactating women
