The effect on blood sugar is actually lowered. As for fruits, patients with high blood sugar should not eat fruits if their blood sugar is not well controlled. If the blood sugar control is up to standard, such as fasting blood sugar less than 7mmol/L and postprandial blood sugar below 8mmol/L, you can choose fruits with low sugar content, such as lychee, strawberry, cherry, kiwi, etc. There is no fruit that can achieve the effect of lowering blood sugar, but just choose low-sugar fruits, which have a low impact on blood sugar.
