During the third month of pregnancy, pregnant women need to eat a balanced and nutritious diet, especially foods rich in protein, folic acid, calcium, iron and zinc. It is recommended to eat animal liver and green leafy vegetables, which are rich in folic acid. In the third month of pregnancy, the fetal organs and nerve tissues are developing rapidly, so adequate supplementation of folic acid can prevent the fetal nervous system development from being affected by folic acid deficiency, resulting in congenital neural tube development malformation. It is also necessary to eat more fish and shrimp foods, which are rich in calcium, iron, zinc and other trace elements and high-quality protein, which are very beneficial to the healthy development of the fetus. At the same time, you need to eat more fresh vegetables and fruits, especially to eat more soy foods that contain more high-quality protein, which can supplement high-quality protein and trace elements such as calcium and phosphorus, which is very helpful for the fetal intellectual development.
