High blood sugar patients should avoid certain foods that can cause their blood sugar levels to rise. Honey, despite its natural composition of glucose and fructose, can cause a rapid increase in blood sugar levels. Similarly, sweet potatoes, although nutritious, contain high levels of sugar. Ice cream, although low in calories, contains high amounts of sugar and should be avoided.
Persimmons, with their abundant fructose, sucrose, and glucose, are not recommended for diabetes patients. Alcohol can also cause a sudden spike in blood sugar, and thus, should be avoided. Lastly, sweetened dried fruit, with its high sugar content, is not suitable for high blood sugar patients.
