Many nutritional deficiencies in pregnant women during pregnancy are caused by poor eating habits during pregnancy. There are two main types of nutritional deficiencies: insufficient intake and insufficient absorption. During pregnancy, pregnant women have increasing demands for nutrients in order to provide adequate nutrition to the fetus in the abdomen. As long as you don't pay attention to your diet during pregnancy, it can easily lead to insufficient nutritional intake during pregnancy and affect the growth and development of the fetus. Therefore, insufficient nutrition during pregnancy is not only detrimental to the health of pregnant women, but also has a significant impact on the development of the fetus.

During pregnancy, dietary nutrition needs to be diverse, and you should not be picky or picky eaters. To achieve a balanced diet, you must pay attention to dietary nutrition, hygiene and safety. After a woman becomes pregnant, her body's demand for nutrients increases. As long as the intake of nutrients is insufficient, the blood supporting the fetus will lack the nutrients needed for fetal growth, thus affecting the growth and development of the fetus. Therefore, during pregnancy, various nutrients should be supplemented in time to allow the fetus to grow and develop normally. Any bad eating habits that interfere with absorption or overeating in picky eaters must be avoided during pregnancy. When malnutrition occurs during pregnancy, the pregnant woman's eating habits need to be adjusted immediately so that the pregnant woman can correct her bad diet in a timely manner and obtain sufficient dietary nutrients in the shortest possible time.

When there is insufficient nutrition during pregnancy, you must first provide more vitamins, ensure protein intake, and eat more milk, eggs, beans and other foods. However, the diet should not be greasy, but should be light and easy to digest. Try to choose foods that pregnant women like, and don’t be picky about food. After pregnancy, pregnant women can ensure the healthy development of the fetus, and their bodies need more than 40 nutrients. Therefore, the diet cannot be single, and the types of meat and vegetables must be diversified. Folic acid and iron-rich foods should be supplemented in early pregnancy to prevent iron deficiency anemia during pregnancy and affect fetal development. Pregnant women have much higher calcium and zinc needs than when they are not pregnant. Eating more foods high in calcium and iron can also prevent malnutrition in pregnant women.

Two methods, first, nutritional supplements, and second, high-quality diet combined with nutritional supplements, but detailed diet planning must be done according to the pregnancy period.
