Decoding the 'Natural Flavors' Controversy
The most prominent health concern raised about LaCroix and similar brands centers on the ambiguous ingredient, "natural flavors". In 2018, a class-action lawsuit was filed against National Beverage Corp., alleging their claim of "all-natural" was false. The suit pointed to specific compounds allegedly found in LaCroix, such as limonene and linalool, which can be found in some pesticides. While the company vehemently denied these claims, the incident sparked public worry..
The science behind the flavors
Scientific sources, including the National Institutes of Health, classify chemicals like limonene and linalool as naturally occurring compounds found in plants and flowers. Linalool, for example, is a naturally occurring terpene alcohol found in many flowers and spice plants, and limonene is a naturally occurring chemical found in citrus peels. The Food and Drug Administration (FDA) has classified these as "Generally Recognized as Safe" (GRAS) for use in food flavorings. Food safety experts have largely dismissed the lawsuit's claims, noting that a plant-derived ingredient also used in an insecticide does not make it a health hazard in the context of food flavorings. In the concentrations used, these natural essences are not considered dangerous.
Potential Effects on Dental Health
One of the most widely discussed health topics related to sparkling water is its effect on tooth enamel. While much healthier than sugary sodas, which combine sugar and acid to create a perfect storm for tooth decay, sparkling water still poses a mild risk due to its carbonation. The process of carbonation creates carbonic acid, which can lower the drink's pH level.
- Plain vs. Flavored: Unflavored sparkling water is minimally erosive. However, the addition of "natural flavor" derived from citrus fruits can increase acidity and lower the pH further, potentially increasing the risk of enamel erosion over time with excessive consumption.
- Soda Comparison: The risk posed by LaCroix is significantly lower than that of soda. Studies have shown that sugary and diet sodas are hundreds of times more acidic than sparkling mineral waters.
- Minimizing Risk: To protect your teeth, dentists recommend drinking sparkling water in moderation, using a straw to minimize contact with teeth, and rinsing your mouth with plain water afterward.
Impact on Digestive Health
For most people, sparkling water has no negative effect on digestion and can even aid in hydration and relief from constipation. However, some individuals with sensitive digestive systems may experience discomfort.
Common Digestive Side Effects:
- Bloating and Gas: The carbon dioxide in sparkling water can cause gas and bloating in sensitive individuals, as the bubbles can lead to a build-up of air in the gastrointestinal tract.
- Aggravated GERD: People with gastroesophageal reflux disease (GERD) might find that the carbonation aggravates their symptoms due to increased gas and pressure in the stomach.
The Truth About PFAS in Sparkling Water
In 2020, a Consumer Reports study found concerning levels of "forever chemicals" (PFAS) in certain sparkling water brands, including LaCroix. PFAS are man-made chemicals that do not break down over time and can accumulate in the environment and the body. They have been linked to various health issues, including high cholesterol and potential cancer risks. While all brands tested were compliant with existing standards at the time, the report highlighted the widespread presence of these chemicals in the environment and drinking water. Fortunately, new regulations and at-home water filters are helping to address this issue.
LaCroix vs. Other Beverages: A Comparative Glance
| Feature | LaCroix Sparkling Water | Sugary Soda | Diet Soda | Tap Water |
|---|---|---|---|---|
| Calories | 0 | ~140+ | 0 | 0 |
| Sugar | 0g | ~39g+ | 0g | 0g |
| Artificial Sweeteners | No | No | Yes | No |
| Acidity (pH) | Mildly acidic (low 4s) | Highly acidic (low 3s) | Highly acidic (low 3s) | Neutral (around 7) |
| Dental Risk | Low (with moderation) | High | High | None |
| Digestive Risk | Low (for most) | Low | Low | None |
The Overall Nutritional Verdict
When evaluating if is there anything unhealthy in LaCroix?, the answer is largely dependent on perspective and consumption habits. Compared to sugary sodas, juice, and other sweetened beverages, LaCroix is unequivocally a healthier choice. It provides a refreshing, flavorful option without adding calories, sugar, or artificial sweeteners to your diet, making it an excellent tool for hydration and weight management.
However, potential downsides are worth considering, especially with frequent consumption. The mild acidity can pose a risk to dental enamel over time, and for those with sensitive stomachs, the carbonation may cause bloating or gas. The presence of trace PFAS chemicals is an environmental concern, though the levels found typically meet existing safety standards. For most healthy individuals, drinking LaCroix in moderation is perfectly safe and can be a valuable part of a balanced diet.
Ultimately, if sparkling water helps you stay hydrated and avoid sugary drinks, the benefits generally outweigh the minimal risks. For those with specific health conditions, such as weakened enamel or GERD, consulting a healthcare professional is advisable. For all-around optimal health, plain water remains the best choice for hydration, but LaCroix offers a flavorful and mostly harmless alternative.

Conclusion: Balancing the Bubbles
While sensationalist headlines about hidden insecticides and synthetic ingredients in the past captured public attention, they were largely unsubstantiated by scientific consensus. The main health considerations with LaCroix are its mild acidity, which can impact dental enamel over years of high consumption, and its carbonation, which can cause minor digestive upset in some. When stacked against sugary soft drinks, LaCroix's lack of calories, sugar, and artificial additives makes it a far superior choice for hydration and overall health. A balanced approach, alternating between plain water and sparkling water, and practicing good oral hygiene, is the most sensible way to enjoy this popular beverage.
