For patients with gestational diabetes, it is permissible to eat dragon fruit. Since dragon fruit contains relatively low sugar levels, it can be consumed. However, it should not be eaten in excess, as excessive consumption can still lead to fluctuations in blood sugar levels. In the treatment of gestational diabetes, we should not cause the pregnant woman's weight to decrease, hence a low-calorie treatment is not advocated. Generally, the total calories are calculated based on standard weight, approximately 30 to 35 kcal per kilogram of body weight per day. Sugars should make up about 50%, proteins 20%-25%, and fats 25%-30%. It is best to divide these into three main meals and three snacks, adjusting the proportion and calorie content of the diet according to body type. Therefore, patients with gestational diabetes can eat dragon fruit, and it can be consumed as a snack between main meals.
