1 水硬度与心血管疾病 1960年,Schroeder提出饮水硬度与心血管疾病死亡率呈负相关。几十年来,已有不少国家做过几十次的研究,揭示饮水与心血管疾病(心脏病、高血压病和脑血管意外等)存在明显统计学联系。钙、镁是组成水硬度的2种主要成分,由饮水提供的钙、镁一般约占总摄入量的5～20％。已知钙、镁含
Water hardness and cardiovascular disease In 1960, Schroeder proposed a negative correlation between drinking water hardness and cardiovascular mortality. For decades, dozens of studies have been conducted in many countries to show that there is a clear statistical relationship between drinking water and cardiovascular diseases (heart disease, hypertension, and cerebrovascular accidents). Calcium and magnesium are the two main components that make up the hardness of water. Calcium and magnesium provided by drinking water generally account for about 5% to 20% of the total intake. Known calcium, magnesium containing
