Diabetic patients can eat crayfish, which is mainly protein-based and has little effect on blood sugar, but there are still issues that diabetics need to pay attention to when eating crayfish. First of all, diabetics should not eat spicy crawfish, because the taste is heavy and may have a certain impact on the blood sugar of diabetics. Second, crawfish can not eat too much, there are reports that crawfish can lead to rhabdomyolysis. In addition, diabetic patients eating crayfish try not to drink beer, which can easily lead to a significant increase in blood uric acid levels in diabetic patients and may even induce an attack of gout.
