The sugar content of apple is about 13.5%, and the main component is monosaccharide, which has high absorption rate. Eating on an empty stomach is easy to cause blood sugar fluctuation. However, diabetics can eat green apples (sour apples). Chromium contained in these apples can improve the sensitivity of diabetic patients to insulin, while malic acid can stabilize blood sugar and prevent senile diabetes. So diabetics should eat sour apples.
Warm reminder: When diabetics eat sour apples, don't forget to calculate the calories of apples and reduce the amount of staple food, preferably between meals.
