Diabetic patients can eat sweet and sour garlic in small quantities, but its sugar content is high and you cannot eat too much at once. Note that it has no hypoglycemic effect. Diabetic patients need to strictly control their diet and avoid foods with high sugar content. Sweet and sour garlic itself contains more sugar, diabetic patients with good blood sugar control can eat appropriately, but must pay attention to control the one-time intake, and pay attention to monitoring blood sugar changes. In addition to certain dietary requirements, diabetic patients also need to pay attention to strengthening exercise and maintaining weight in daily life. Once there is a sharp fluctuation in blood glucose values, you need to consult a doctor in time for observation and standardized treatment under the guidance of clinicians to prevent delays.
