人体含铁量仅约4g,但在体内却发挥着重要的生理作用、诸如参加构成血红蛋白、肌红蛋白以及许多酶系。随着人们对铁营养重要性的认识、铁吸收率问题正日益受到广泛的关注。因此发展和验证各种客观、有效的铁吸收测量方法有助于解答不同年龄段、不同生理状态下人群铁吸收率 The body’s iron content is only about 4g, but it plays an important physiological role in the body, such as participating in the formation of hemoglobin, myoglobin, and many enzymes. With people’s understanding of the importance of iron nutrition, the issue of iron absorption is gaining more and more attention. Therefore, the development and validation of various objective and effective iron absorption measurement methods help to answer different age groups, different physiological state of the population iron absorption rate
