Eating stinky tofu when pregnant has little effect on the fetus as long as it does not cause symptoms such as abdominal pain, diarrhea and acute gastroenteritis and is eaten once in a while. It is not recommended to eat fermented foods after pregnancy because these foods produce nitrite, bacteria or viruses during the production process, and improper handling can lead to food poisoning, abdominal pain, diarrhea, fever and other symptoms in pregnant women, which can adversely affect the development of the fetus and the pregnant woman’s body. Pregnant women should eat fresh food, such as fresh vegetables and lean meat, eggs, milk, etc., which can replenish high-quality protein and increase dietary fiber, and supplement a variety of vitamins and minerals.
