Carbonated Water Unsweetened (1 Can Or Bottle (16 Fl Oz))

Choose plain, unflavored carbonated water and check the label for added sugar, juice, syrups, or sweeteners that may affect glucose.

Drink carbonated water alongside a balanced meal rather than on an empty stomach if you notice a rise.

Pair it with protein or healthy fats, such as a boiled egg, plain Greek yogurt, nuts, or avocado, to help steady your glucose response.

Avoid combining it with refined-carbohydrate snacks; choose options like hummus with non-starchy vegetables or cheese with cucumber instead.

Sip slowly and keep portions moderate, especially if the beverage is flavored or contains additives.

Track the specific brand, flavor, timing, and your glucose response, since plain carbonated water itself typically has little effect.
