Osteoporosis, a common problem of older women in developed countries, is characterised by low bone mineral density or low bone mineral content, both measures of bone quantity. However, with osteoporosis there is also a loss of bone micro-architecture--that is, a loss of bone quality. Dietary factors thought to be important in maintaining bone quantity include calcium, vitamin D, protein and salt. Trace minerals may be important in maintaining bone quality through their role as metallo-enzymes in the synthesis of collagen and other proteins that form the structure of bone. Other substances like flavonoids may also have a role in preventing osteoporosis.
骨质疏松症是发达国家老年女性的常见问题,其特征是骨矿物质密度低或骨矿物质含量低,这两者都是衡量骨量的指标。然而,患有骨质疏松症时还会出现骨微结构丧失,即骨质流失。据认为,对维持骨量很重要的饮食因素包括钙、维生素D、蛋白质和盐。微量矿物质可能通过其作为金属酶在合成构成骨结构的胶原蛋白和其他蛋白质中的作用,对维持骨质很重要。其他物质如类黄酮在预防骨质疏松症方面可能也有作用。
