Introduction
We often restrict children from consuming unhealthy junk food; similarly, we do not recommend that pregnant women eat such foods. Healthy options—such as fresh vegetables and fruits—are perfectly acceptable and encouraged. However, we advise pregnant women to limit their intake of pickled foods, preserved eggs (century eggs), and foods high in oil or sugar. Additionally, smoking and alcohol consumption must be completely avoided during pregnancy, as they are unequivocally harmful to fetal development.
During pregnancy, expectant mothers are highly concerned about which foods are safe to eat and which should be avoided. In fact, a simple guiding principle applies: foods commonly considered unhealthy or “junk food” for children—such as highly processed snacks, sugary drinks, and fast food—are likewise not recommended during pregnancy. Conversely, nutritious options—including fresh fruits and vegetables, whole grains, lean proteins, and other wholesome foods—are perfectly suitable and encouraged.
However, pregnant women should avoid frequent consumption of pickled or cured foods—such as pickled vegetables, cured meats (e.g., bacon or dried sausages), or fermented tofu (doubanjiang or furu). These products undergo mold fermentation, and their consumption may cause gastrointestinal discomfort.
Another commonly consumed item at home is preserved eggs (century eggs). During their production, lead is inevitably introduced; as a heavy metal, lead interferes with the absorption of essential trace elements—including calcium, iron, and zinc—and may adversely affect fetal development. Therefore, regular or excessive consumption is discouraged. Occasional, minimal intake, however, poses no significant risk.
Similarly, foods high in fat and sugar—such as fried foods—should be limited during pregnancy. Excessive intake contributes to rapid maternal weight gain, macrosomia (excessive fetal growth), elevated blood glucose levels, and increased long-term risk of cardiovascular disease.
Lastly, tobacco and alcohol must be strictly avoided. Smoking and drinking alcohol are unequivocally harmful to fetal development. Pregnant women are strongly advised to quit both smoking and alcohol consumption entirely. If quitting smoking proves difficult, it is critical to avoid smoke-filled environments and minimize exposure to secondhand smoke.
