先前报道的膳食钙摄入量与血压水平的负相关性在南加州社区进行了检查，以确定这种相关性是否与年龄、肥胖和饮酒无关。在总人口中，与血压正常的男性（但女性除外）相比，高血压患者从牛奶中摄入的钙明显减少，并且这种关联与年龄和肥胖无关。在该队列中 23% 的男性子样本中，通过 24 小时饮食回忆估计了所有乳制品中膳食钙摄入总量的影响。同样，高血压男性消耗的钙量明显低于血压正常男性。在男性中，收缩压和舒张压水平与乳制品中钙的摄入量呈负相关。在控制年龄、肥胖和酒精后，舒张压与乳制品中的总钙摄入量呈显着负相关，而收缩压同样与仅全脂奶钙相关。尽管这些数据是横断面的，但它们表明乳制品的某些成分（可能是钙）对高血压具有保护作用，并且与在高血压易感大鼠中报道的钙的保护作用相一致。
The previously reported inverse association of dietary calcium intake and blood pressure levels was examined in a Southern California community, in order to determine whether this association was independent of age, obesity, and alcohol consumption. In the total population significantly less calcium intake from milk was reported in hypertensive versus normotensive men (but not women) and the association was independent of age and obesity. In a 23% subsample of men from this cohort the effect of total dietary calcium intake from all dairy products was estimated from a 24-h dietary recall. Again hypertensive men consumed significantly less calcium than normotensives. In men, both systolic and diastolic blood pressure levels were inversely associated with calcium intake from dairy products. After controlling for age, obesity, and alcohol, diastolic blood pressure was negatively and significantly associated with total calcium intake from dairy products, while systolic blood pressure was similarly associated with whole milk calcium alone. Although these data are cross-sectional, they suggest that some component of dairy products, probably calcium, exerts a protective effect against hypertension, and are compatible with the protective effect of calcium reported in hypertension-prone rats.
