When experiencing signs of threatened miscarriage, pregnant women should choose foods rich in vitamins and pay attention to a light diet, eating food that is easy to digest and absorb. They should avoid spicy and stimulating foods, as well as raw and cold seafood or other barbecue and hot pot foods, to prevent diarrhea and aggravate the miscarriage. When choosing foods, one can opt for soy products, fresh vegetables, fruits, lean meats, eggs, and walnuts. Additionally, it is advisable to select foods that are rich in vitamin E, which supports pregnancy, such as some soy products. It is also beneficial to choose foods containing roughage but avoid cold foods and thermogenic foods like longan, as longan is very heaty and should be avoided as it might induce miscarriage.
