In western countries， nearly all the salt in our diets comes from the food industry and 80% of the salt we eat is already put in the food before we have any control. So the main target in western countries is to get the food industry to slowly reduce the amount of salt. That has been very successful in the United Kingdom. Most of the products in the UK have been reduced in terms of their salt content by about 30%. That means that everyone has a reduction in salt intake while they still go on eating the same foods as normal. As much as we would like to， we are not trying to change the diet of people， but rather just reduce the salt intake. The problem in Asian-Pacific areas， in particular northern China， is that most of the salt is added by the consumer. In this case you have to try to persuade the consumer to use less salt. This is much more difficult because you have got to persuade them that it is a toxic substance that is killing millions of Chinese. They have to stop using it in such large quantities. The beauty of that is that if you do start to slowly reduce salt intake， people actually get used to food with less salt， salt taste receptors become more sensitive， and people will then much prefer food with less salt.
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. 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 do 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 from sodium.
西方国家国民饮食中80%的食盐来自食品工业，因此其控盐的主要目标是缓慢减少食品工业用盐量。而在亚太地区特别是中国北方，大部分高盐饮食取决于家庭或个人行为。因此须对广大公众进行宣教，或通过开展公共卫生运动告知其高盐饮食的危害。另一方法是采用由氯化钠、氯化钾和氯化镁混合而成的矿物盐来替代常规的氯化钠。在中国已有研究显示用矿物盐替代普通食盐能降低血压。
