During the new pneumonia epidemic, pregnant women should pay attention to the following dietary concerns: 1) A balanced, light diet, and avoid over-eating and weight control. 2. Ensure dietary diversity and pay attention to the intake of trace elements such as folic acid, iron and iodine. Folic acid needs to be supplemented from the first three months of pregnancy and can be supplemented until after delivery; pregnant women often eat iron-rich foods to help prevent anemia during pregnancy; the need for iodine during pregnancy is nearly double that of non-pregnancy, and the safest way to supplement is to eat iodized salt. 3.Pay attention to dietary hygiene. 4. Prohibit smoking and alcohol, because they have a particularly strong influence on the embryo. At the same time, pregnant women should pay attention to avoid passive smoking.
