Children can eat salt in small amounts after one year of age. After one year of age, the kidney function development has gradually matured, and the kidney function can reach about 90% of the adult kidney function, so you can eat a little salt. When children do not like to eat light food, such as noodles, vegetables, etc., you can add a small amount of salt to the food, but be careful not to have too much at a time, so as not to increase the burden on the kidneys. Salt is not suitable for children before they are one year old because the kidneys of children before one year old are not well developed, and eating too much salt may affect the development of the kidneys and so on. Before one year of age, the daily salt requirement is less than 0.5 grams, and it is generally not recommended to add extra salt to complementary foods. If your child is not feeling well after eating a large amount of salt, it is recommended that you seek prompt medical attention.
