Generally, it is clinically recommended that babies under one week of age should not eat salt, and after one week of age, salt can be added in small amounts for flavor.
Babies within one week of age do not need to add salt to their daily complementary foods. This is because both formula and complementary foods contain a certain amount of sodium ions, which can satisfy the baby’s daily needs. In addition, this time the baby’s kidney function is not yet fully developed, too early to add salt will not only increase the burden on the baby’s kidneys.
Since the sodium naturally present in breast milk, formula and complementary foods is already sufficient for babies’ body needs, there is no need to add additional salt and other flavorings.
After the baby is one year old, you can start to add a small amount of salt for seasoning. According to the Dietary Guidelines for Chinese Residents, children aged 2-3 years old should have a salt intake of less than 2 grams per day, including salt, soy sauce and other seasonings.
