High blood sugar is not necessarily allowed to eat mangoes, and it depends on the patient’s blood sugar level. The pulp of mango is rich in protein, crude fiber as well as vitamin A, a large amount of vitamin C and minerals, which can provide rich nutrition, while the dietary guideline for hyperglycemia is limited and not taboo, so if the blood sugar level is within the controllable range, you can eat less. If fasting blood sugar can be controlled at 6.5-7.5mmol/L and 2h postprandial blood sugar can be controlled at 8.5mmol/L or less, you can eat some mangoes appropriately. However, it should be noted that mangoes belong to fruits with medium sugar content, with sugar content of 12%-16%. If blood sugar control does not meet the standard, such as fasting blood sugar ≥ 8.0mmol/L and 2h postprandial blood sugar ≥ 11.0mmol/L, it is not recommended to eat mangoes. Patients with high blood sugar, including those with impaired fasting blood sugar or abnormal glucose tolerance, both of which belong to pre-diabetes, should preferably have their diet controlled according to the diabetic diet, and these two patients can eat half a mango between meals. When blood sugar control reaches the standard, you can eat some fruits with sugar content of 10%-20%, in addition to mango, you can also eat apples, pears, kiwi, watermelon, etc.. But try not to eat fruits with high sugar content such as sugar cane, bananas, durian, dates, etc. The sugar content of these foods are above 20%, and diabetic patients who consume such fruits can easily lead to an increase in blood sugar, so try to eat less.
