If you have kids who also like to indulge in bubbly water, “I would say in general it’s fine,” Dr. Seymour said. But, she added, “I wouldn’t do it everyday with my daughter.” Ideally, parents should encourage their children to drink still, fluoridated water to guard against cavities, she said, and reserve the sparkling water for special occasions.
Carbonated beverages can also contribute to gas and bloating, but the degree varies from person to person.
“When you swallow carbonation it has to come out somewhere, so you either belch it out or it’s passed through flatulence,” said Courtney Schuchmann, a registered dietitian at University of Chicago Medicine who specializes in gastrointestinal health. “If you’re someone who already has issues with gas and bloating, it can cause more symptoms for you.”
Carbonation can also make acid reflux worse and have a “filling effect,” which may diminish your appetite by creating distention in your belly, she added.
Regardless of what type of water is preferred, Ms. Schuchmann said she typically counsels her clients to drink about half their body weight in ounces, assuming they have a normal body mass index. Those fluids can also include coffee, tea and the water in fruits and vegetables. But there is no hard and fast rule about how much water to drink each day, she added, because it depends on many factors, including your body size, activity level, environment, medical conditions and so on.
Something else to keep in mind: Many people assume club soda and seltzer water are interchangeable, however club soda usually has sodium.
“For someone watching their blood pressure, that is something to take into consideration,” Ms. Schuchmann said. “It depends on what the rest of your diet looks like and how much sodium is coming from other sources.”
