Patients with high blood sugar can eat cherries in small amounts if their blood sugar is well controlled. If the blood sugar control is not up to standard, it is recommended not to eat them, and then eat them in small amounts after the blood sugar reaches the standard. The amount of cherries eaten depends on the degree of the patient’s blood sugar control: 1, patients with impaired fasting blood sugar or abnormal glucose tolerance can eat 8-10 cherries between meals; 2, diabetic patients can eat 4-6 cherries between meals if their blood sugar control is basically up to standard, such as fasting blood sugar control at 6.5-7.5 mmol/L and blood sugar control at 8.5 mmol/L or less two hours after meals. 3, diabetic patients with substandard blood sugar control, fasting blood sugar ≥ 8.0mmol/L, two hours after meals blood sugar ≥ 11.5mmol/L, it is recommended that such patients should not eat cherries, can eat some food that does not raise blood sugar, including cucumbers, tomatoes; 4, diabetic patients with acute infections, including ketoacidosis, lung infection, urinary tract infection, skin infection, the diabetic foot, etc., in the stage of serious infection is also not recommended to eat cherries, so as not to cause substantial fluctuations in blood sugar. Patients with high blood sugar mainly eat fruits with a sugar content of 10-20%.
