Magnesium, an element involved in a variety of biochemical and physiological processes in the human body, is closely linked to maintaining health and preventing disease. Even so, studies on the status of magnesium intake have never been conducted sufficiently since only recently a dietary reference intake value was proposed, and data on magnesium contents in food items have always been insufficient. Therefore, in this study, we selected 366 food items commonly consumed by Korean people and then analyzed their magnesium content with inductively coupled plasma atomic emission spectroscopy. With these results, we evaluated daily magnesium intake in 239 healthy adult males and females. Using these 366 values based on magnesium content measurements, we evaluated the status of magnesium intake by our participants and found that the average daily magnesium intake was 279.2 mg, 90.4% of the recommended intake (RI). The results also showed that the magnesium intake by 54.8% of the subjects was lower than the estimated average requirement. In addition to this, the magnesium intake by 45.2% of the cohort was less than 75% of the RI. As such, a high percentage of the subjects showed inappropriate magnesium intake.
镁是人体中多种生化和生理过程所涉及的元素，与维持健康和预防疾病密切相关。即便如此，由于直到最近才提出膳食参考摄入量值，而且食物中镁含量的数据一直不足，因此，关于镁摄入量的研究从未充分进行过。因此，在这项研究中，我们选择了 366 种韩国人常吃的食物，并使用电感耦合等离子体原子发射光谱法对其镁含量进行了分析。根据这些结果，我们评估了 239 名健康成年男性和女性的每日镁摄入量。使用这些基于镁含量测量的 366 个值，我们评估了参与者的镁摄入量状况，发现平均每日镁摄入量为 279.2mg，达到推荐摄入量（RI）的 90.4%。结果还表明，54.8%的研究对象的镁摄入量低于估计的平均需求量。此外，45.2%的队列的镁摄入量低于 RI 的 75%。因此，很大比例的研究对象显示出不合适的镁摄入量。
