At what age can babies start consuming salt?

       Generally speaking, babies may gradually begin consuming salt after their first birthday. However, additional salt is not necessary and, if used, should be added in moderation according to the child’s age.

       A baby’s requirement for salt primarily serves to replenish sodium. Complementary foods are typically introduced starting at 6 months of age, during which time the recommended daily sodium intake is 350 mg. Sodium is naturally present not only in table salt but also in breast milk/formula, vegetables, meat, and eggs—thus, no additional salt supplementation is needed. For children aged 1 to 3 years, the daily sodium requirement increases to 700 mg, at which point small amounts of salt may be introduced into the diet. However, infants’ and toddlers’ kidneys are still immature and their metabolic capacity remains relatively weak; excessive salt intake may adversely affect their health.
