降低血压的饮食习惯

为了腰围和血压，不要捧着一碗冰淇淋或一盒饼干大吃特吃了，相反，你可以选择吃一块黑巧克力。恒星含量超过80%的巧克力可能会通过抑制血管紧张素转化酶（ACE）降低血压--就像你能在药房买到的ACE抑制剂一样。血管紧张素是人体分泌出的强效化学物质，会导致血管周围的肌肉收缩，从而使血压升高。

Lower Your Sodium Intake

减少钠的摄入量

But don't exclude salt completely. Although the Mayo Clinic, The American Heart Association, and the National Heart, Lung, and Blood Institute have all called for a reduction in sodium intake for people with high blood pressure, a study involving more than 130,000 participants has concluded that "low-salt diets in people with and without high blood pressure may actually increase the risk of cardiovascular disease and death compared to average salt consumption." In response to these findings, the American Heart Association has reaffirmed their position that 1,500 milligrams of salt daily is best for ideal heart health.

但不要彻底不吃盐。尽管梅奥诊所、美国心脏协会和国家心肺血液研究所都呼吁高血压病人减少钠的摄入量，但一项涉及13万名参与者的研究已得出这样的结论："相比盐摄入量正常的人群，摄入低盐饮食的高血压病人和正常人群实则可能会增加患冠心病的风险，死亡率也相对高些"。为回应这些研究结果，美国心脏协会重申他们的立场：想要心脏健康？最好每天只摄入1500毫克的盐。
