About Unflavored Sparkling Water
One cup of plain unflavored sparkling water provides zero calories and no protein, carbohydrate, fat, fiber, or net carbs. Its glycemic index and glycemic load are zero.
Sparkling water is water containing dissolved carbon dioxide. Products sold as seltzer generally contain little beyond water and carbonation, while club soda and mineral water may contain measurable sodium, calcium, magnesium, or other minerals depending on the formulation or natural source.
This entry represents unsweetened, unflavored carbonated water with no juice, sugar, syrup, caffeine, or artificial sweetener. Tonic water and regular flavored soda are not equivalent because they commonly contain added sugar and calories.
