Most people are told to drink more water daily. But many struggle to meet hydration goals, leading to creative alternatives like seltzer. Seltzer, or carbonated water, has surged in popularity, with brands releasing a wide range of flavors (even Guy Fieri has his own line). The key question is: is it as hydrating as plain water? And how does daily seltzer consumption affect dental health?
Registered Dietitian Amy Davis confirms that plain seltzer hydrates just as effectively as still water because it’s essentially water with added carbon dioxide. This makes it a viable option for those who prefer the bubbly sensation. Hydration needs vary based on age, weight, and activity level. A common rule of thumb is to drink half your body weight in ounces of water daily, including fluids from food and other beverages.
However, excessive carbonation can worsen bloating, reflux, or gas in sensitive individuals. It’s crucial to differentiate between seltzer and other bubbly drinks like soda water, sparkling water, or tonic, which often contain sodium, minerals, or sweeteners.
Dental health impacts are minimal with plain seltzer. According to Dr. Brittany Seymour of the American Dental Association, research shows plain sparkling water affects tooth enamel similarly to regular water. Still, she recommends fluoridated water as the primary daily beverage to combat cavities and dryness.
Citrus-flavored seltzers pose a greater risk due to their acidity, potentially damaging enamel. If consumed, it’s best to drink them in one sitting, preferably during meals when saliva production is high. Avoiding additives or sweeteners in seltzer is also advised.
Ultimately, seltzer can be a healthy way to reach hydration goals when consumed in moderation. Combining plain water with seltzer is a practical approach, as long as you avoid excessive citrus or added sugars.
