介绍了硒元素对生物体的健康功效及不合理摄入硒对人体造成的危害，从硒在人体的吸收、转运角度解释了硒的生物利用率的含义，总结了硒在人体的吸收代谢情况、生物利用率的测定方法及当前研究现状、硒生物利用率的影响因素，初步得出补硒关键控制点，为提高硒的生物利用率提供理论依据。

Advances on Bioavailability of Selenium in Dietary Sources

The health effects of selenium on human body and the harm caused by irrational intake of selenium were introduced. The meaning of selenium bioavailability was explained from the selenium absorption and transport in human body. The absorption and transport of selenium, the determination method of bioavailability， research status, and the influencing factors of selenium bioavailability were all summarized. With critical control of selenium supplement, these results provided a theoretical basis for improving the bioavailability of selenium.
