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.
Benefits of moderate intake:
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.
