A pilot survey was made of the dietary calcium intake of normotensive and hypertensive individuals. Compared to 44 normotensive controls, 46 subjects with essential hypertension reported significantly less daily calcium ingestion (668 +/- 55 milligrams compared to 886 +/- 89 milligrams). The intake of other nutrients, including sodium and potassium, was very similar in the two groups. The hypertensives differed from the controls primarily in their consumption of nonfluid dairy products. The data suggest that inadequate calcium intake may be a previously unrecognized factor in the development of hypertension.
对血压正常和高血压个体的膳食钙摄入量进行了一项初步调查。与44名血压正常的对照组相比，46名原发性高血压患者报告的每日钙摄入量显著较少（分别为668±55毫克和886±89毫克）。两组中其他营养素的摄入量，包括钠和钾，非常相似。高血压患者与对照组的主要差异在于非流质乳制品的摄入量。数据表明，钙摄入不足可能是高血压发病过程中一个以前未被认识到的因素。
