Mangosteen can be eaten in small quantities by patients with high blood sugar, but its high sugar content makes it not recommended to consume too much of it, especially when blood sugar control is poor. Note that mangosteen does not have a hypoglycemic effect. Mangosteen contains vitamin E, vitamin B and other vitamins, as well as potassium, magnesium, calcium and other minerals. Diabetic patients can eat mangosteen appropriately, which helps to supplement nutrients and promote health. However, mangosteen has a high sugar content, and it is not recommended that patients with high blood sugar eat a lot of mangosteen at one time, so as not to cause too much blood sugar increase, which is not conducive to maintaining blood sugar stability. Patients with high blood sugar can eat apples, oranges, pears, grapefruit and other fruits with low glycemic index to control blood sugar. Patients diagnosed with hyperglycemia should maintain a healthy diet, take appropriate physical exercise, and cooperate with doctors for active treatment.
