As long as there are no added sugars, sparkling water is just as healthy as still water. Unlike sodas, sparkling waters don't affect your bone density or greatly damage teeth. They can make you feel gassy or bloated, so you may want to avoid them if you have gastrointestinal issues. Drinking sparkling water can help you stay more hydrated throughout the day. Many people find that sparkling water tastes better and is easier to drink than regular tap or spring water. However, Sparkling has the same health benefits as spring water, in that it will keep your body hydrated. There are claims that carbonation increases calcium loss in bones, causes tooth decay, causes irritable bowel syndrome (IBS), and can make you gain weight even without the calories, sugar, and flavor that are found in regular soda. Research shows that sparkling water can help aid digestion. One study with 21 participants found that drinking sparkling water relieved indigestion and constipation.
