You can eat doughnuts during pregnancy, but it is not recommended to eat them regularly. Doughnuts are a common staple food. If pregnant women have been in the habit of eating doughnuts, they can eat them appropriately, but it is recommended to eat them in small amounts or reduce the number of times they are eaten. Because doughnuts are high-temperature fried foods, they are very high in calories and very greasy, so eating more of them can easily increase the feeling of satiety, thus reducing the intake of other foods. In addition, the oil used for frying doughnuts may be used repeatedly, which will cause the grease to age and the odor to increase, and the doughnuts are mainly made of flour, and for the sake of loose taste, many doughnuts add alum, which contains aluminum and may cause brain development disorders when consumed regularly. Therefore, pregnant women can eat doughnuts in moderation, and it is best to fry some at home to ensure the hygiene of the ingredients used. The diet of pregnant women should be diversified, you can choose cereal porridge, whole wheat bread, milk, soy products, etc., with fresh vegetables and fruits, and less oily, spicy and stimulating food.
