It is better to eat folic acid, protein, vitamins and minerals in the first 3 months of pregnancy. 1. Folic acid: women should take folic acid tablets during the first 3 months of pregnancy. Folic acid is a water-soluble vitamin, and the amount you can get from food is relatively small, so additional supplementation of folic acid tablets can prevent the development of fetal neural tube defects. 2. Protein: the first three months of pregnancy should be supplemented with protein-rich foods, such as milk, eggs, beef, fish, in order to ensure the normal functioning of the body and the supply of nutrients to the embryo, which is conducive to the normal growth and development of the embryo. 3. Vitamins and minerals: vitamins and minerals are indispensable trace elements of the human body, and are also very important to the growth and development of the fetus during pregnancy, such as apples, bananas, kiwi, spinach, lettuce, animal liver and other foods. Nutrition should be balanced in the first 3 months of pregnancy, you can eat small meals and avoid overeating.
