The Surprising Benefits of a Daily Seltzer Habit
For many, drinking plain water is unappealing. This is where seltzer water shines, offering a bubbly, zero-calorie, and flavorful alternative that can significantly boost your daily fluid intake. It is equally as hydrating as regular water, provided it is unsweetened and free of additives. This makes it an invaluable tool for those aiming to reduce their consumption of high-calorie, sugar-laden beverages like soda and juice, which are linked to weight gain and an increased risk of type 2 diabetes.
Can Seltzer Aid Digestion?
Some evidence suggests that seltzer water can positively impact digestion. Studies have found that carbonated water may help improve swallowing ability in both young and older adults. The fizz can also increase feelings of fullness after meals, which can be beneficial for appetite control. Furthermore, some individuals find that carbonation helps alleviate constipation and indigestion.
Understanding the Potential Drawbacks
While generally safe, daily seltzer consumption is not without its potential downsides. Awareness of these issues can help you make informed choices.
Seltzer and Dental Health: A Look at the Acidity
One of the most persistent concerns about seltzer is its effect on tooth enamel. When carbon dioxide is infused into water, it creates a slightly acidic carbonic acid. The pH of plain seltzer typically falls between 5 and 6, which is more acidic than regular water (neutral at a pH of 7), but far less acidic than soda or even orange juice. Repeated exposure to any acid can potentially lead to enamel erosion over time. However, the risk is minimal for plain, unflavored seltzer, especially when compared to sugar-sweetened beverages where bacteria feed on sugar and produce more damaging acid.
Digestive Discomfort: Bloating and Gas
The very bubbles that make seltzer appealing can also cause digestive issues in some people. The carbonation can lead to gas, bloating, burping, and other gastrointestinal discomfort. Those with sensitive stomachs, irritable bowel syndrome (IBS), or gastroesophageal reflux disease (GERD) may find that carbonated drinks worsen their symptoms. If you experience these side effects, limiting or cutting back on your seltzer intake may be beneficial.
Additives to Watch For
Not all seltzer is created equal. Many flavored options contain citric acid to enhance the taste, which can further increase the acidity level and pose a higher risk to dental enamel. Some club sodas also contain added sodium, which can be a concern for those with high blood pressure. The healthiest choice is always plain, unsweetened seltzer.
Seltzer and Bone Health: Busting the Myth
A common myth is that carbonated water negatively impacts bone health by leaching calcium. However, this is largely a misconception stemming from studies on cola, which contains phosphoric acid and caffeine that can interfere with calcium absorption. Plain seltzer does not contain these ingredients, and studies have shown no negative effect on bone density from consuming carbonated water. Some sparkling mineral waters even contain bone-boosting minerals like calcium and magnesium.
Best Practices for Daily Seltzer Drinkers
Here are some tips to mitigate any potential risks and enjoy your daily bubbly beverage safely:
- Moderation is key: Limit your intake to one to three cans per day, alternating with regular water.
- Drink with meals: Enjoying seltzer during meals stimulates saliva production, which helps to neutralize the acid in your mouth.
- Use a straw: This minimizes contact between the acidic carbonated water and your tooth enamel.
- Rinse with plain water: Swish your mouth with tap water after drinking seltzer to wash away any residual acid.
- Check the label: Choose plain, unsweetened varieties to avoid added sugars, artificial sweeteners, or excessive sodium.
- Balance with tap water: Since tap water contains fluoride, which strengthens teeth, it's important to still drink plenty of it alongside your seltzer habit.
Comparison: Plain Seltzer vs. Other Beverages
| Feature | Plain Seltzer | Flavored/Sweetened Seltzer | Sugary Soda | Still Water | Other Info |
|---|---|---|---|---|---|
| Hydration | Excellent | Excellent (if no sugar) | Good (but counteracted by sugar) | Excellent | All are hydrating sources of fluids |
| Calories | Zero | Variable (check label) | High | Zero | Depends heavily on additives |
| Dental Risk | Low (some acidity) | Medium (added citric acid) | High (sugar + high acidity) | None | Best to rinse mouth after consumption |
| Digestive Impact | Possible bloating/gas | Possible bloating/gas | Can cause indigestion | None | Individual tolerance varies |
| Added Sugar | No | Possible (check label) | Yes, significant | No | Unsweetened is the healthiest choice |
| Additives | Carbon dioxide | Flavoring, citric acid | Sugar, phosphoric acid, color | None | Read ingredient labels carefully |
Conclusion: Seltzer is Safe, But Moderation Matters
For most people, drinking seltzer water every day is a perfectly healthy and hydrating choice. It provides a refreshing, zero-calorie alternative that can help curb cravings for sugary drinks and contribute to your overall fluid intake. The key takeaway is moderation and conscious consumerism. By opting for plain, unsweetened varieties and taking simple preventative measures like using a straw or drinking with meals, you can enjoy your bubbly habit without significant risk to your dental or digestive health. It's a great stepping stone towards better hydration, as long as it complements, rather than completely replaces, your intake of still, fluoridated water.

What are the main benefits of drinking seltzer water every day?
Better Hydration: Seltzer is just as hydrating as regular water and can encourage people who dislike plain water to drink more throughout the day, helping them meet their daily fluid needs. Weight Management: By replacing sugary beverages like soda or juice with zero-calorie seltzer, you can reduce your overall calorie and sugar intake, which supports weight management goals. Reduced Sugar Intake: It helps cut down on added sugars, which are linked to various health issues including obesity, type 2 diabetes, and heart disease.
What are the risks of drinking seltzer water every day?
Digestive Upset: The carbonation in seltzer can cause bloating, gas, and burping in some individuals, especially those with sensitive stomachs or conditions like IBS or GERD. Tooth Enamel Erosion: While plain seltzer's acidity is mild, frequent, and prolonged exposure can potentially lead to minor enamel erosion over a long period. Flavored seltzers are more acidic due to added citric acid. Missing Fluoride: Relying solely on bottled seltzer means you miss out on fluoride, a mineral found in most tap water that helps strengthen tooth enamel.
Is seltzer water bad for your teeth?
No, not inherently: Plain, unsweetened seltzer is not considered bad for your teeth, especially when consumed in moderation. Its acidity is much lower than sugary sodas or juices. To be safe, dental experts recommend drinking it with meals, using a straw, or rinsing your mouth with plain water afterward.
Does seltzer water cause bloating or gas?
Possibly: The carbon dioxide bubbles in seltzer can lead to gas and bloating for some individuals, as the gas gets trapped in the stomach. This effect is highly individual; if you experience discomfort, it's best to reduce your intake.
Does seltzer water affect bone health?
No: The rumor that carbonated water leaches calcium from bones is a myth, likely conflated with concerns about cola beverages containing phosphoric acid. Plain seltzer water has no negative effect on bone density. In fact, some mineral waters contain minerals that support bone health.
How much seltzer is too much to drink daily?
Listen to your body: There is no universal limit, as individual tolerance varies. Generally, one to three cans of plain seltzer per day is safe for most people. If you experience side effects like bloating, gas, or heartburn, or if your dentist expresses concern about your enamel, it may be a sign to cut back.
What should I look for when buying seltzer water?
Read the label carefully: For the healthiest option, choose plain, unsweetened seltzer water with no artificial sweeteners. Be aware that some flavored versions contain added citric acid that can increase acidity. If you have high blood pressure, check for added sodium, as found in some club sodas.
What's the best way to enjoy seltzer water while minimizing dental risk?
Practice safe sipping: To minimize contact with your teeth, use a straw. Drink it alongside a meal when saliva production is higher to help neutralize acids. After finishing, rinse your mouth with a sip of plain tap water to wash away any remaining acid.
Is flavored seltzer water okay to drink every day?
Use caution: Flavored seltzers can be more acidic due to added citric acid, increasing the risk of enamel erosion over time. While better than sugary sodas, they are not as innocuous as plain seltzer. Enjoying flavored varieties in moderation and using a straw is the safest approach for your teeth.
What about sparkling mineral water versus seltzer water?
Slight differences: Sparkling mineral water is naturally carbonated from a spring and may contain beneficial minerals like calcium and magnesium. Seltzer is simply water infused with carbon dioxide. Both are hydrating, but seltzer allows you to infuse your own flavors while mineral water comes pre-packaged with a natural mineral content.
Can seltzer water cause kidney stones?
No: There is no evidence linking plain seltzer water to kidney stones. This myth likely originates from confusion with colas, which contain phosphoric acid. Seltzer can actually help you stay hydrated, which is crucial for kidney health. However, individuals with existing kidney disease or those on sodium-restricted diets should be cautious with high-sodium beverages like some club sodas.
Who should not drink seltzer water every day?
Those with sensitivities: Individuals with sensitive gastrointestinal tracts, IBS, GERD, or an overactive bladder may find that carbonation worsens their symptoms. Those at high risk for dental decay or who have been advised by a dentist to reduce acidic intake may also want to limit consumption. Always listen to your body and consult a healthcare provider with concerns.
