Carbonated/sparkling water is currently enjoying a big boost in popularity. Drinks like LaCroix, Bubly, Topo Chico, and San Pellegrino are helping people cut sodas out of their lives. They’re calorie free, naturally flavored, and give you that sharp and bubbly bite without all the bad stuff that comes along with soda.
•It’s just as hydrating as water.
•Carbonation doesn’t add calories.
•It doesn’t leach calcium from your bones. This rumor got started from a study showing that cola affects bone density, but this study wasn’t looking at sparkling water. Later studies showed that neither the water nor carbonation had any impact on bones.
•Sparkling mineral water usually contains more minerals than still/flat water, but this varies by location.
•Some varieties of carbonated water such as club soda have small amounts of sodium (3% DV).
•Carbonic acid (a byproduct of water and carbon gas) gives carbonated water its slightly tangy taste. The acid is weak though, and so is the impact on your teeth. Flavors of the citrus variety may also have increased acids, but it was found they’re no more acidic than fruit juice.
•Carbonated water will fill you up faster, which may keep you from drinking as much water as you need to stay fully hydrated.
So the biggest negatives found in sparkling water are that the bubbles will fill you up faster than flat water and acids may be higher than flat water, but still not bad. It’s still a great choice instead of sugary sodas. Be on the lookout for ones that add sweeteners (and also calories) though, and make sure to also drink plenty of regular flat water.
