When the diet is too salty, a large number of sodium ions enter the blood circulation, and a large amount of water will remain in the blood vessels, which will increase the blood volume, increase the burden on the heart, and increase the pressure on the blood vessel wall, which will eventually lead to an increase in blood pressure. According to a survey, residents in a certain area of Japan eat an average of 25 grams of salt every day, and people suffering from hypertension account for 30% ~ 40% of all residents. In other parts of the world, only 5 ~ 15g salt is eaten every day, and only 8% ~ 10% people suffer from hypertension. Inuit living in the Arctic Circle eat less than 5 grams of salt every day, and almost no one suffers from high blood pressure. At present, the average daily salt intake of urban and rural residents in China is 12g, which is 2.4 times the recommended value of the World Health Organization. In order to prevent serious chronic diseases such as hypertension, it is urgent to advocate a light and low-salt diet.
