It is generally recommended that babies over six months can eat DHA properly. In addition, the diet is also rich in DHA components, such as seafood, fish and shrimp, so babies who add complementary foods can add these foods rich in DHA appropriately. DHA, also known as brain gold, is an unsaturated fatty acid. DHA is a very important component for the growth and maintenance of cells in the nervous system and an important component of the brain and retina. DHA is as high as 20% in the human cerebral cortex, and accounts for a relatively large proportion in the retina of the eyes, accounting for about 50%, so DHA is very important for the development of children's intelligence and vision. Generally, mothers can eat DHA in moderation during pregnancy, so if they are breast-fed babies, the DHA contained in the mother's milk can meet the needs of growth and development. If the baby is artificially fed or fed with milk powder, a proper amount of DHA is generally added to the milk powder, which can meet the needs of DHA. Therefore, if the baby needs to supplement DHA, it is recommended that the baby over six months can supplement it appropriately.
