Level 1: Nutritional issues that need attention during pregnancy. During pregnancy, pregnant women need to consume more nutrients to meet the needs of the fetus and themselves. However, if pregnant women do not pay enough attention to their diet, they may suffer from malnutrition. In order to avoid this from happening, pregnant women need to pay attention to the following points: 1. Balanced diet: Pregnant women should ensure that they consume enough nutrients such as protein, carbohydrates, fats, vitamins and minerals every day. In addition, you should try to avoid eating too many fried foods and high-calorie foods. 2. Supplement folic acid: Folic acid is an important nutrient for preventing fetal neural tube defects.
