Children's renal function is not fully developed, and they can't effectively discharge excess sodium ions like adults. Therefore, children need less salt than adults. According to the recommendations of the World Health Organization, the daily salt intake of children aged 65,438+0-3 should not exceed 2g, that of children aged 4-6 should not exceed 3g and that of children aged 7-65,438+00 should not exceed 5g.
In contrast, the daily salt intake of adults should be controlled below 6 grams. This is because excessive intake of sodium increases the risk of diseases such as hypertension, heart disease and stroke.
In addition, some studies show that long-term high-salt diet may have negative effects on children's physical development, such as affecting bone growth and intellectual development. Therefore, in order to protect children's health, parents should try to reduce adding too much salt to their children.
