Diabetics can eat a little bit of 85% dark chocolate in small amounts if their blood sugar is well controlled and monitor blood sugar changes. With the increase of cocoa content, the sugar content of dark chocolate has decreased. 85% dark chocolate contains less sugar compared with other candies, so diabetic patients can eat a little less if their blood sugar is well controlled. However, 85% dark chocolate still contains a certain amount of sugar, which can raise blood glucose after consumption. Therefore, it is not recommended for diabetic patients to eat more, especially those with poor blood glucose control should try not to eat. At the same time, attention should be paid to the total calories of the day’s food to avoid excessive calories affecting blood sugar and aggravating the condition. Diabetic patients should take medication on time and in accordance with the doctor’s instructions. It is also recommended that patients eat a proper diet under the guidance of a doctor, mixing coarse and fine, eating a balanced diet, eating more fresh vegetables and fruits, and eating less sugary food.
