<International Circulation>:   What are some tactics we could use in places where people are adding the salt themselves?  
 

  《国际循环》：那么您认为在那些人们自己添加大量食盐的地方我们用什么办法来促使他们减少食盐摄入量呢？
    Prof. MacGregor: It is necessary to have a public health campaign telling them how dangerous it is and make it clear to them that they should be using less salt.  Another way is to use a mineral salt， which is a mixture of sodium chloride， potassium chloride， and magnesium chloride.  There is a salt company in Japan that already has a salt such as this available.  It is possible that it would be better to use that one in place of regular sodium chloride.  There have been studies in China showing that mineral salt substitutes does lower blood pressure.  It may well be that this is another tactic that could be used to get people to replace regular salt with mineral salt.  That would be a very quick way of changing things.  Actually， potassium has the opposite effect on blood pressure than sodium.

    MacGregor教授：很必要进行一场公共卫生运动来告诉他们摄入过量的食盐有多大的危害，并且让他们意识到自己应该使用更少的盐。另一种方法是使用矿物盐，矿物盐是一种氯化钠、氯化钾和氯化镁的混合物。在日本有一家盐业公司已经推出了这样的食用性矿物盐。用这种矿物盐来替代常规的氯化钠可能更好。在中国已经有研究显示用矿物盐替代普通食盐能使血压更低。很可能这是另一种使人们用矿物盐替代普通食盐的策略。这会是一种改变现状的快速途径。实际上，钾和钠在对血压的影响上具有相反的作用。
