The dietary principles for gestational diabetes are consistent with those for non-pregnant diabetes. Firstly, the total daily caloric intake should be balanced, with carbohydrates accounting for 50%-60%, proteins for 15%-20%, and fats for 20%-30%. The overall principle is to eat smaller, more frequent meals, ideally adding two to three snacks to the three main meals per day. Common foods primarily include milk, proteins, egg whites, and fruits. Then, generally maintain the level of diet before pregnancy without overly restricting it. It is advisable to consume a significant amount of vegetables, no less than 500 grams daily, to supplement vitamins and fiber.
