Diabetic patients can eat mangosteen, but the amount of mangosteen to eat needs to be analyzed according to the patient’s blood sugar. Usually, diabetic patients with stable blood sugar control can eat a moderate amount of mangosteen, while those with poor blood sugar control are not recommended to eat mangosteen. Mangosteen is rich in nutrients, including sugar, vitamins, proteins and lipids, which can supplement the body’s nutritional needs, but it also contains more sugar. 1. Diabetic patients with stable blood glucose control generally mean that fasting blood glucose is controlled within 7 mmol/L and 2-hour postprandial blood glucose is controlled within 10 mmol/L. Eating mangosteen in moderation has certain benefits for the body. But be sure to control the amount of consumption, you can eat a small amount between meals, so as not to consume too much, affecting blood sugar levels. 2. People with poor glycemic control, which generally refers to fasting blood glucose more than 7mmol/L and 2-hour postprandial blood glucose more than 10mmol/L, should try not to consume mangosteen, so as not to elevate blood glucose and aggravate the condition. In short, diabetic patients should be under the guidance of the doctor to develop a diet plan, while combining moderate exercise and hypoglycemic drugs, scientific and reasonable lowering of blood sugar. If you feel unwell, you should seek medical advice promptly.
