Babies and young children do not need to eat salt within one year of age, the sodium content in breast milk and formula is already sufficient, early intake of additional salt is likely to affect the development of the baby’s sense of taste, so it is recommended that babies start eating salt after one year of age. Babies within one year of age are not completely unable to eat salt, but it is recommended to consume it after one year of age. Premature intake of salt by babies is likely to affect the development of the child’s taste buds, as babies have a more sensitive sense of taste than adults, so food that adults may find salty or bland is appropriate becomes very salty in the mouth of babies. It has a certain impact on the eating habits afterwards. In addition to salt, seasonings such as soy sauce and chicken essence, which contain a certain amount of salt, are also not recommended for babies within one year of age. After one year of age, they can gradually change to an adult diet, and can add salt in small amounts.
