美《科学文摘》1982年3月报道:饮用硬水的人可能在他们的肠道内设立肥皂工厂,减少对脂肪的吸收,因而有助于预防心脏病。上述理论是由得克萨斯大学医学部的道森(Earl Dawson)医生提出的。过去十多年来的研究己表明,世界范围内凡有硬水的地区,心脏病的发病率较低。事实上,最近对得克萨斯州22个居民区的调查表明,硬水区心脏病的死亡率比一般地区要低25％,血压和血清胆固醇水平均较低,尽管他们也报告了每天摄入的脂肪量比生活在软水区的人高。硬水的预防因素尚未明确。但道森认为,决定水硬度的主要矿物质钙、镁的含量高是有重要关系的。他说,钙、镁在肠道内与来自食物
The United States, “Science Digest” reported in March 1982: people who drink hard water may set up soap factory in their intestines to reduce the absorption of fat, which helps prevent heart disease. The theory was put forward by Dr. Earl Dawson of the University of Texas Medical Department. Research over the past decade or so has shown that in areas with hard water worldwide, the incidence of heart disease is low. In fact, a recent survey of 22 residential areas in Texas showed that heart attacks in hard-water areas have a 25% lower mortality rate than those in the general area, with lower blood pressure and serum cholesterol levels, although they also reported daily fat intake Higher than those living in soft water areas. The preventive factors of hard water is not yet clear. However, Dawson believes that it is important to determine the high levels of calcium and magnesium, the major mineral water hardness. He said calcium and magnesium are in the gut and come from food
