Daily intake of salt per capita

The daily intake of salt should be controlled within 5 grams. The Healthy China Action (20 19-2030) pointed out that the survey results in 20 12 years showed that the daily salt intake per capita of China residents was 10.5g, and the World Health Organization recommended that the daily salt intake per capita was 5g in 20 13 years. According to the nutritional health status and dietary status of Chinese residents, the state proposes to gradually reduce the intake of salt. The National Nutrition Plan (20 17-2030) puts forward the goal of reducing the national average daily salt intake by 20% by 2030, and the Dietary Guidelines for China Residents (20 16) points out that the daily salt intake of adults should not exceed 6 grams. On this basis, the country advocates that the intake of 5g recommended by WHO should be in line in the near future.

1 g salt contains 0.4 g sodium. Salt is sodium chloride, so sodium ions and chloride ions often coexist in food, and the proportion of sodium is close to 40%, so 1 gram of sodium can be converted into 2.5 grams of salt. When buying processed food, multiply the sodium content in the nutrient composition table by 2.5 to get its salt content. People often ask why the sodium content of some foods is not 0, such as milk and soybean milk, because there is obviously no salt in the ingredient list. In fact, all animal and plant foods naturally contain sodium, and the difference is only how much. Feeling slightly salty requires about 0. 1%~0.2% salt. The appropriate salinity of soup is 0.5%, that is, 500 mg/100 g salt, and the mouth weight is 0.7%. So although there are dozens of milligrams of sodium in milk, it is basically not salty.

Daily intake of 1500 mg sodium can meet the needs of human body, which is beneficial to the prevention of hypertension. Although salt reduction has been advocated, the lower the salt intake, the better. Because sodium ion is the main component of extracellular fluid, it is extremely important to maintain blood osmotic pressure, water balance and ion balance in vivo, which is an important factor to regulate blood pressure. Sodium ion is also essential for maintaining the transmission of nerve impulses and muscle contraction. Sodium is an essential nutrient. If the dietary intake is too low, it is difficult to meet the physiological needs of the human body. It is found that the diet containing sodium1500mg (equivalent to 3.75g of salt) is beneficial to prevent hypertension, and there will be no problem of sodium deficiency.

1 g salt is equivalent to about 6 ml of soy sauce. In addition to edible salt, there are many seasonings containing a lot of salt, such as soy sauce, sweet noodle sauce, lobster sauce, fermented bean curd, monosodium glutamate and chicken essence. Among them, 1 g salt is equivalent to about 6 ml of soy sauce. Therefore, after using these seasonings, it is necessary to put less or even no salt.
