4 min read

According to a 2025 study in the Journal of Nutritional Science and Vitaminology, plain carbonated water hydrates just as effectively as still water. Is drinking plain soda water good for health, or are the fizzes hiding a health risk? While a satisfying alternative to sugary sodas, plain soda water has both pros and cons that require a closer look.

Quick Summary

This article explores the health impacts of plain soda water, examining its effects on hydration, dental health, digestion, and weight management. It clarifies the differences between various carbonated beverages and offers guidance on how to consume them mindfully to maximize benefits and minimize risks. It addresses common misconceptions about bone density and the body's pH balance.

Key Points

  • Equally Hydrating: Plain soda water hydrates just as effectively as still water, making it a good fluid source.

  • Weight Management Aid: The carbonation can increase feelings of fullness, potentially helping to manage appetite and reduce calorie intake.

  • Dental Health Caution: Plain soda water is mildly acidic, posing a low risk to teeth in moderation. Flavored versions with citric acid are more erosive.

  • Digestive Effects Vary: For some, it can relieve indigestion and constipation, but for others with sensitive stomachs, it may cause bloating or gas.

  • Sugar-Free Alternative: As long as it's unflavored and unsweetened, it's a superior alternative to sugary sodas for satisfying fizz cravings.

  • No Bone Density Risk: Contrary to a popular myth, plain sparkling water does not cause bone density loss.

  • Listen to Your Body: If you experience digestive discomfort, it's best to reduce intake or switch back to still water.

Hydration and Weight Management: Does It Measure Up?

From a hydration standpoint, plain soda water is just as effective as still water. For individuals who find plain water unappealing, the effervescence can make meeting daily fluid intake more enjoyable. This is a significant benefit, especially when used as a substitute for high-calorie, sugary soft drinks like soda, which are linked to weight gain and type 2 diabetes.

Benefits for Satiety

Another key benefit is its potential role in weight management. The carbonation in soda water can create a feeling of fullness or satiety, which may help curb appetite and reduce overall calorie consumption. The bubbles expand in the stomach, sending signals of fullness to the brain and potentially delaying gastric emptying. This makes plain soda water a useful tool for those looking to reduce their intake of empty calories from sugary beverages.

Dental Health: Is the Fizz a Hazard?

One of the most persistent concerns about carbonated beverages is their effect on dental health. The carbonation process introduces carbon dioxide gas into water, which creates a weak carbonic acid. This makes plain sparkling water mildly acidic, with a pH typically between 4.9 and 5.5. This is more acidic than plain water, which has a neutral pH of 7, but significantly less acidic than sugary soft drinks or fruit juices. Enamel erosion, which can lead to cavities and sensitivity, can begin at a pH of 5.5 or lower.

Plain soda water, when consumed in moderation, poses a low risk to dental health. However, flavored sparkling waters often contain added citric acid, which can lower the pH further and increase the risk of enamel damage. For frequent consumers, drinking through a straw can minimize direct contact with teeth, and drinking with meals can help stimulate saliva flow, which neutralizes acids.

Digestive Impact: Aid or Agitator?

The effect of soda water on digestion varies greatly among individuals. For some, the carbonation can be beneficial, aiding in the relief of indigestion and constipation by promoting regular bowel movements. Studies have also shown that the bubbles can improve swallowing ability, particularly in older adults.

Conversely, the carbonation can cause uncomfortable symptoms like gas, bloating, and belching in others. Individuals with conditions like gastroesophageal reflux disease (GERD) or irritable bowel syndrome (IBS) may find that carbonated drinks exacerbate their symptoms. Listening to your body is crucial; if you experience discomfort, opting for still water is the safer choice.

Comparison Table: Plain Soda Water vs. Still Water

Feature Plain Soda Water Still Water
Hydration Just as effective for hydration as still water. The foundational source for hydration, universally effective.
Calories & Sugar 0 calories, 0 sugar (for plain varieties). 0 calories, 0 sugar.
Dental Health Mildly acidic; low risk of enamel erosion in moderation. Higher risk with added flavors. Neutral pH; the safest option for teeth.
Digestive Impact Can aid digestion and satiety for some, but may cause bloating for those with sensitivities. Gentle on the digestive system; no risk of bloating from carbonation.
Taste & Enjoyment Crisp, bubbly, and refreshing. A satisfying alternative to sugary drinks. Smooth, neutral taste. Can be less exciting for some palettes.
Minerals Seltzer: no minerals. Club Soda & Mineral Water: may contain added minerals like sodium or calcium. Contains minerals depending on the source; typically no added minerals.

Conclusion

In summary, drinking plain soda water can be a healthy part of a balanced lifestyle, especially as a calorie-free, sugar-free alternative to soft drinks. It is just as hydrating as still water and may even aid digestion for some individuals. The risks, primarily mild acidity affecting teeth and potential bloating for sensitive stomachs, can be managed with mindful consumption. The key lies in choosing plain, unsweetened varieties and listening to your body's response. For those seeking the safest option, still water remains the gold standard, but for a refreshing, bubbly twist on hydration, plain soda water is a viable and generally safe choice. Always check the ingredient label for added acids, sweeteners, or sodium, which can change the health profile of the beverage entirely.

Can you drink sparkling water every day?

Yes, drinking plain sparkling water every day is generally safe for most people, as long as it's consumed in moderation. Opt for unsweetened versions and pay attention to how your body, particularly your stomach and teeth, reacts.

Is sparkling water bad for your kidneys?

No, there is no evidence that plain carbonated water is bad for healthy kidneys or causes kidney stones. In fact, staying hydrated with sparkling water can help prevent them. However, individuals with pre-existing kidney conditions may need to monitor mineral intake, especially sodium, found in some club sodas.

What are some tips for drinking sparkling water safely?

  • Choose unsweetened and unflavored varieties to minimize acidity.
  • Drink it with meals to stimulate saliva, which helps neutralize acid.
  • Use a straw to reduce direct contact with your teeth.
  • Rinse your mouth with plain water after consumption.
  • Listen to your body; if you experience bloating or acid reflux, reduce your intake or switch to still water.
