Sugar-free colas are not recommended for diabetics. It is not recommended that diabetic patients drink sugar-free cola, although sugar-free cola does not contain sugar, but it contains sweeteners, such as aspartame, sucralose, etc. Although sweeteners do not raise blood glucose, long-term intake of sweeteners will also increase the risk of high blood pressure and obesity, so it is not recommended that diabetic patients drink sugar-free cola, and it is recommended that they drink plenty of plain water, which can promote metabolism. Diabetic patients should maintain a healthy diet, avoiding drinks and fried food, etc. They should control the total calorie intake, eat a balanced diet, and monitor their blood glucose regularly to screen for complications.
