Ice cream is not recommended for high blood sugar. Ice cream contains many kinds of sugar, milk powder, margarine and vegetable oil, which contain high calories and high carbohydrate content. People with high blood sugar, especially diabetics, will have significantly higher blood sugar after eating ice cream. High blood sugar can aggravate the complications of diabetes, such as diabetic ketoacidosis, diabetic nephropathy and so on. It may seriously affect the quality of life of diabetic patients. When blood sugar is high, it is recommended to control blood sugar in the ideal state, which can be done by controlling the diet and eating more low-fat and low-calorie foods, and avoiding high-calorie and high-fat foods, such as ice cream and other foods with high sugar content, so as not to elevate blood sugar. You should also pay attention to proper exercise and maintain your weight so that your blood sugar is controlled at a normal level. Seek prompt medical attention if you find abnormal blood sugar levels.
