Relationship of sodium intake and blood pressure varies with energy intake:secondary analysis of the DASH(dietary approaches to stop hypertension)-sodium trial
摘要膳食钠的摄入量是以绝对量(mg/d)表示而不是以钠密度(mg/kcal)表示的。研究者旨在确定钠摄入量与血压关系的强弱是否随着能量摄入量而变化。终止高血压膳食研究(dietary approaches to stop hypertension,DASH)-钠试验是比较2种膳食(DASH和对照)和3种钠密度水平的随机膳食摄入试验。
