Generally speaking, infants can add vegetable oils such as olive oil to complementary foods after 7 months of age, and salt can be added appropriately after 1 year of age.
Because breast milk can still provide infants with the nutrients they need before the age of 6 months, and the digestive ability of infants is not yet perfect, so it is not recommended to add complementary foods at this time. 7 months after the age of 7 months, you can consume some vegetable oils to supplement the unsaturated fatty acids needed by the human body in order to promote the development of the brain and optic nerve. But be careful not to overdose, to prevent indigestion and diarrhea.
Salt consumption needs to wait until the infant is 1 year old, as early consumption of salt will increase the burden on the infant’s kidneys. Therefore, it is not recommended to consume salt before 1 year of age, and after 1 year of age, salt intake should be controlled, and the diet should be light.
In conclusion, when adding complementary foods to infants, it is important to follow the order from less to more, and stick to a light diet and a variety of diets to ensure the healthy growth of children.
