Why is the amount of salt eaten reduced to five grams a day?

Original title: Why is the amount of salt eaten every day down to five grams
Nowadays, the importance of salt reduction to health is well known to everyone, but how much do you really know about salt? In this issue, let's take a deep look at it with some numbers.
daily salt intake should be limited to 5 grams. Health China Action (2019-2030) points out that the 2012 survey results showed that the average daily salt intake of Chinese residents was 10.5 grams, and in 2013 the World Health Organization recommended a recommended daily salt intake of 5 grams per capita. According to the nutritional health status and diet status of our residents, the state recommends gradually reducing salt intake. The National Nutrition Plan (2017-2030) states that "by 2030, we will achieve the national goal of reducing daily salt intake by 20% per capita" and the Dietary Guidelines for Chinese Residents (2016) state that adults should consume no more than 6 grams of salt per day. On this basis, countries advocate alignment with the 5 g intake recommended to WHO in the near future.

1 g of salt contains 0.4 g of sodium. Salt is sodium chloride, so sodium and chloride ions often exist in food at the same time, of which the proportion of sodium is close to 40%, so 1 g of sodium can be adjusted to 2.5 g salt. When you buy processed foods, multiply the sodium content in the nutritional table by 2.5 to produce its salt content. It is often asked why some foods do not have 0 sodium content, such as milk, soy milk, etc. In fact, all animal and plant foods naturally contain sodium, just how much difference. It takes about 0.1% to 0.2% salt to feel slightly salty. The proper saltiness of the soup is 0.5%, which is 500 mg/100 g of salt, and the mouth weight is 0.7%. So although milk has dozens of milligrams of sodium, it is basically not savoury.
1,500 milligrams of sodium a day to meet human needs and help prevent high blood pressure. Although salt reduction has been advocated, salt intake is not as low as possible. Because sodium ions are the main component of extracellular fluid, it is very important to maintain blood osmotic pressure, water balance and ion balance in the body, and is an important factor in regulating blood pressure. Sodium ions are also essential for maintaining the transmission of nerve impulses and muscle contraction. Sodium is an essential nutrient, if the dietary intake is too low to meet the physiological needs of the human body. The study found that a diet containing 1,500 milligrams of sodium (equivalent to 3.75 grams of salt) helps prevent high blood pressure and does not cause sodium deficiency.
1 gram of salt is equivalent to about 6 milliliters of soy sauce. In addition to cooking salt, there are many seasonings are salty, such as soy sauce, sweet pasta sauce, soy meal, rotting milk, MSG, chicken essence, etc. , of which 1 gram of salt is equivalent to about 6 ml of soy sauce. Therefore, the use of these seasonings to put less or even no salt.
