Diabetic patients should try not to drink Coke Zero. Although Coke Zero contains very little sugar and is a sugar-free drink from its advertisement, this drink itself contains calories and as a carbonated drink, it is not good for the control of the condition of diabetic patients. Because carbonated drinks have other elements besides sugar, these elements have an effect on the function of the patient’s pancreatic islet cells. In order to avoid this effect, in order to release the toxic effects, it is better for diabetic patients not to drink Coke Zero, which is from the point of view of caloric control as well as from the point of view of protection of islet cell function. If you want to drink beverages, try to choose non-carbonated beverages, because they are closer to nature, healthier and have more benefits for the control of the patient’s condition, the regulation of blood sugar and the prevention of long-term complications.
