Can I drink sugarcane juice if my blood sugar is high?

Sugarcane juice contains a lot of sugar, and sucrose is easily converted into glucose in the human body, which affects the insulin secretion in diabetic patients. The more you eat, the higher your blood sugar will be. When patients with high blood sugar eat sugarcane, if their blood sugar exceeds the normal limit, it will promote the growth and reproduction of staphylococci on the skin, which can easily cause small boils or furuncles on the skin. If the bacteria invade deep into the skin, it may cause bacteremia. In addition, excessive intake of sugar can also cause excessive production of acidic metabolites in the body, making the blood acidic, which is very detrimental to the health of patients with high blood sugar. Therefore, experts recommend that patients with high blood sugar should not eat sugarcane.
