Infants generally should not have salt.
Before six months of age, infants are mainly fed with breast milk and formula milk and do not need to use salt. After six months, infants start to eat complementary foods, and there is no need to add salt in the process of making complementary foods for infants, because infants have not eaten salt and do not retain the taste of salt, and infants can eat complementary foods without added salt.
Eating salt too early for infants is harmful to their growth and development. Infants’ kidneys and other organs are not fully developed, and eating too much salt during infancy will easily increase the load on the kidneys and lead to kidney damage, which will in turn affect the development of renal function in infants. For safety reasons, it is recommended not to give salt to infants during infancy.
After the child is one year old, parents can start to put salt in the complementary food, but remember to moderate, do not let the toddler eat too salty.
