本文调查了内蒙古牧区牧民老年人和城市老年人150名头发中的宏量元素钙、镁的含量,并对它们与人体健康、疾病、衰老等方面进行了研究。研究结果表明,牧区牧民的Ca含量自60岁以后高于同龄城市组,牧区组75岁以后,城市组65岁以后为最低。Mg的含量,在70岁以前城市组普遍高于牧区组。牧民体内的Ca,Mg缺乏,容易患心血管疾病、神经系统疾病、骨代谢疾病等,平均寿命也短。这主要是由于:牧民的膳食结构不合理,摄取营养素不全,营养比例失调等。
This paper investigates the contents of calcium and magnesium in 150 hair of herdsmen in the pastoral areas of Inner Mongolia and the elderly in urban areas, and studies their health, disease, aging and so on. The results showed that the Ca content of herdsmen in pastoral areas was higher than that in the same age group since the age of 60, and the lowest in the urban group after the age of 65 after 75 years of age. The content of Mg is generally higher in the urban group than in the pastoral group before the age of 70. Herdsmen lack of Ca, Mg, susceptible to cardiovascular disease, nervous system diseases, bone metabolism disease, the average life expectancy is also short. This is mainly due to: unreasonable diet structure of pastoralists, inadequate intake of nutrients, nutritional imbalances and so on.
