目的对乌鲁木齐市售的补钙类保健食品进行客观评估,为长期服用者提供理论参考依据。方法用火焰原子吸收法测定保健食品中钙元素的含量,并与国家规定日摄入量进行比较。结果总体上产品规定的每日摄入钙量基本合理,未超过国民膳食营养素每日最高耐受量,但长期服用钙加维生素D类保健食品应防止蓄积中毒。结论富含钙元素的保健食品可作为一些特殊情况下机体补钙的方式,但应注意长期服用而引发的问题。
Objective To evaluate the calcium supplement health food in Urumqi and provide theoretical reference for long-term users. Methods The contents of calcium in health food were determined by flame atomic absorption spectrometry and compared with the national daily intake. Results As a whole, the daily intake of calcium regulated by the product was basically reasonable and did not exceed the daily maximum tolerated level of national dietary nutrients. However, long-term use of calcium plus vitamin D type health food should prevent accumulation of poisoning. Conclusion Calcium-rich health foods can be used as a way to supplement calcium in some special situations, but care should be taken for long-term use.
