Half of the baby\’s intellectual development comes from genetic inheritance. Of course, innate development also plays a role, especially the mother\’s nutritional intake during pregnancy. Pregnancy is an important stage for the baby\’s intellectual development. Expectant mothers can promote the baby\’s intellectual development through a reasonable diet. 1. The Importance of Omega-3 Fatty Acids 1. Omega-3 fatty acids are important substances in the synthesis of cell membranes and are crucial to the intellectual development of babies. During pregnancy, the fetal organs are constantly developing, which requires a large amount of omega-3 fatty acids. Expectant mothers should consume more foods rich in omega-3 fatty acids in early pregnancy to meet the needs of fetal growth and development. If the mother-to-be consumes insufficient omega-3 fatty acids, the fetus will automatically absorb this substance from the mother\’s body, and the mother-to-be may be deficient in omega-3 fatty acids. Therefore, the mother-to-be must take supplements rich in omega-3 fatty acids in a timely manner. Foods with gal-3 fatty acids. 2. Foods containing omega-3 fatty acids mainly come from deep-sea fish. DHA in deep-sea fish is rich in omega-3 fatty acids, which promotes the development of the baby\’s eyes. After the baby is born, the mother will find that the baby\’s eyes are bright and bright. Therefore, expectant mothers can eat more foods rich in omega-3 fatty acids, such as tiger grouper, cod, and eel. Of course, regarding the diet during pregnancy, expectant mothers should also pay attention to the choice of fish and cooking methods to avoid ingesting mercury-containing deep-sea fish. 2. The effect of bird\’s nest on intellectual development. After the expectant mother is pregnant for 3 months, the body organs of the embryo begin to form and differentiate. Therefore, the embryo in the later stages of pregnancy will gradually transform into a \”fetus\”. During the second and third trimester of pregnancy, the fetus needs more nutrients to develop. Therefore, bird\’s nest, as an extremely nutritious health product, plays an important role in the development of the fetus. Bird\’s nest is rich in nutrients. First of all, the sialic acid content in bird\’s nest is very high. The neuraminic acid contained in the bird\’s nest is very important for the development of the fetus\’s intelligence and immune system. On the other hand, it is good for the baby\’s brain development. A lot of force. In addition, bird\’s nest also contains an active factor-epidermal growth factor, which can prevent the occurrence of stretch marks and has certain benefits for the skin of mothers and fetuses. Therefore, expectant mothers can consume bird\’s nest in moderation to promote the intellectual development of the fetus and improve immunity. However, pregnant mothers should pay attention to the distinction when purchasing bird\’s nests, because there are many counterfeit bird\’s nests on the market. In order to ensure that you buy truly authentic bird\’s nests, pregnant mothers should shop around, check their qualifications, and purchase through formal channels. Pregnancy is a critical period for the baby\’s intellectual development. The expectant mother\’s diet has a great impact on the baby\’s intellectual development. Throughout pregnancy, pregnant mothers should pay attention to balanced nutrition and choose healthy foods to lay a good foundation for the baby\’s intellectual development.
