Drinking milk tea can cause a rise in blood glucose levels. The main ingredients of milk tea and their impact on blood sugar levels are as follows: milk tea usually contains high amounts of sugar, such as white sugar and glucose. These sugars are rapidly absorbed by the human body after consumption, leading to an increase in blood glucose levels. Moreover, other ingredients in milk tea such as creamer, solid fillers, and liquid fillers may also contain certain amounts of sugar or substances that can be converted into sugar, further contributing to elevated blood glucose levels. A 750ml cup of milk tea may contain up to 99g of sugar; even if the vendor claims no added sugar, its sugar content may still exceed recommended limits. Therefore, both healthy individuals and people with diabetes may experience elevated blood sugar levels after drinking milk tea. For diabetic patients, such a sharp increase in blood sugar is particularly harmful and may worsen the condition or trigger complications.
