Supermarket cod chunks can be given to infants as a complementary food, but attention should be paid to the age of adding the complementary food in months and whether there are any uncomfortable symptoms after adding the complementary food. After the baby is 7 months old, you can gradually add some fish supplements, so as to provide nutrition for the body. Cod has a relatively high nutritional value, rich in vitamin A and vitamin D, but also contains a large number of unsaturated fatty acids and a variety of minerals, which can provide essential nutrients for the development of the baby’s body, and is relatively easy to digest and absorb. However, when eating cod for infants, we must pay attention to the meat minced into a puree, and later give the baby to eat, and can not add salt, because cod itself is a sea fish, which contains a certain amount of salt, if you add salt, it will lead to a heavier burden on the kidneys. And pay attention to any allergic reactions. Although babies can eat cod fish, but parents should not let babies eat too much to avoid indigestion and excessive salt intake.
