选项 A.People used salt to control blood pressure．
B.People ate much salt in their average diet．
C.People were clear about the harmful effect of salt．
D.People didn ’t eat so much salt as we do today．
答案 D
解析 文章第二段提到，过去食物中的含盐量很低，人们只会在做饭的时候加入适量的盐，而现在的加工食品的含盐量过高，人们日常饮食中超过四分之三的盐来自加工食品。因此过去人们盐的摄入量比现在要少。故选D。
