Eating too much durian will generally not cause diabetes, but its sugar content is high and should not be consumed in excess. The glycemic index of durian is at a high level among fruits, but most diabetes develops under the combined effect of genetic and environmental factors, so just eating too much durian will not generally cause diabetes. Although eating too much durian does not cause diabetes, diabetic patients who eat a large amount of durian at one time may cause excessive elevation of blood glucose, which is not conducive to blood glucose control. Genetic predisposition to diabetes, coupled with a poor lifestyle, such as lack of exercise, overnutrition, etc., may trigger the development of type 2 diabetes, so in order to prevent diabetes in daily life should maintain a healthy lifestyle. In case of abnormal blood glucose values it is recommended to visit a hospital and ask the doctor to make a judgment.
