流行病学调查发现：人体内的铁贮量与慢性疾病的危险度有一定关系。根据一些单餐的铁吸收状况的研究表明：许多膳食因素可以影响非含铁血红素铁的生物利用率。但在一些独立生活的老年人群中，这些饮食因素与铁贮存量之间有什么关系问题目前所知不多。为了说明这一问题，我们在 Epidemiological survey found that: the body’s iron storage and the risk of chronic diseases have a certain relationship. Studies of the iron absorption status of some single meals show that many dietary factors can affect the bioavailability of non-heme iron. However, in some elderly people living independently, what is the relationship between these dietary factors and iron storage is not known until now. In order to illustrate this issue, we are here
