When a threatened miscarriage occurs, pregnant women should not eat chili peppers. This is because chili peppers are spicy and stimulating foods, and consuming them can easily lead to abdominal pain, diarrhea, and reflexively cause uterine contractions, which may result in miscarriage. After a threatened miscarriage occurs, it is essential to pay attention to diet. It is recommended to eat light, easy-to-digest foods, such as thin porridge, soft noodles, or soft bread. Additionally, it is important to increase the intake of fresh vegetables and fruits. These supplements of vitamins and proteins can enhance the immune capacity of pregnant women and strengthen their resistance, which is also helpful for successful pregnancy maintenance.
