Is tonic water good for diabetics?

No. Tonic water should generally be avoided by individuals with diabetes as it typically contains significant amounts of added sugar or high-fructose corn syrup, similar to regular sodas. These sweeteners cause a rapid increase in blood sugar levels and are, therefore, not suitable for individuals with diabetes. However, there are brands and versions of tonic water specifically labelled as "sugar-free" or "diet" that use artificial sweeteners such as aspartame or stevia, which do not affect blood sugar levels as sugar does. Diabetic individuals seeking to consume tonic water should carefully read ingredient labels and opt for those with no added sugar, artificial sweeteners, or other carbohydrate sources.
