The Core Ingredients: A Side-by-Side Look
At its most basic level, the difference between water and LaCroix is a matter of purity and additions. Water, in its purest form, is simply H2O—the essential nutrient our bodies need to survive. It contains no calories, no flavorings, and no additives. LaCroix, on the other hand, is a carbonated beverage. Its ingredients list reveals only two components: carbonated water and "natural flavor".
What are these "natural flavors"? The company states they are derived from natural essence oils extracted from the named fruit used in each flavor. While a 2018 lawsuit questioned the 'natural' claim, citing ingredients like limonene (found in citrus peels) and linalool (found in flowers), food science experts and regulatory bodies have clarified that these are common, naturally occurring chemicals that are considered safe for consumption in these quantities. Furthermore, LaCroix contains no sugars, calories, sodium, or artificial sweeteners.
Hydration: Is Bubbly Water as Effective as Still Water?
One of the most common questions regarding sparkling water is whether it hydrates as effectively as still water. The answer, according to numerous sources, is yes. Research published in the American Journal of Clinical Nutrition found no difference in hydration effects between still and sparkling water. The effervescence does not hinder the body's ability to absorb fluids. In fact, for some individuals, the enjoyable fizzy sensation and flavor of LaCroix may actually encourage them to drink more and, therefore, stay more hydrated than they would by drinking plain water alone. This makes it a valuable tool for those who find plain water unappealing.
Potential Health Considerations
While LaCroix is a healthy alternative to sugary drinks, it is not without a few potential considerations, particularly when compared to plain water.
The Dental Debate: Acidity and Enamel Erosion
The carbonation in sparkling water creates carbonic acid, which makes the water slightly more acidic than still water. This has led to concerns about potential tooth enamel erosion. However, multiple studies have concluded that this effect is minimal, especially compared to the highly corrosive nature of sodas and fruit juices. For example, one study found soft drinks to be 100 times more corrosive than any sparkling water. The risk is slightly higher with citrus-flavored sparkling waters, as the additional fruit acid can increase the overall acidity. To mitigate any minimal risk, experts suggest using a straw or rinsing your mouth with plain water after consumption.
Digestive Effects: Bloating and Gas
For some people with sensitive digestive systems, the carbonation in sparkling water can lead to gastrointestinal discomfort. The gas bubbles can cause bloating, burping, or a feeling of fullness. While for some this can be a positive effect that helps with satiety, for others it can be a nuisance. This is a non-issue with plain water.
The 'Natural Flavor' Controversy
As mentioned earlier, the ingredients labeled "natural flavor" in LaCroix faced a lawsuit. The lawsuit cited components like limonene and linalool, but regulatory bodies and scientific experts dismissed concerns about their safety in the context of flavored beverages. The fact that these are naturally occurring chemicals in many fruits and flowers, and present in such small amounts, means they pose no significant health risk when consumed at normal levels.
Water vs. LaCroix: A Comparison Table
| Feature | Plain Water | LaCroix Sparkling Water |
|---|---|---|
| Ingredients | H2O | Carbonated water, natural flavor |
| Calories | 0 | 0 |
| Sugar | 0g | 0g |
| Sodium | Variable (often 0) | 0mg |
| Acidity (pH) | Neutral (approx. 7) | Slightly Acidic (approx. 3-5) |
| Hydration | Fully Hydrating | Fully Hydrating |
| Dental Risk | None | Minimal; slightly elevated with citrus flavors |
| Digestive Impact | None | Possible bloating or gas for some |
| Cost | Typically lower | Higher than tap water |
The Verdict: When to Choose Each Beverage
Plain water is the most fundamental and purest form of hydration available. It is free of any potential risks associated with acidity or carbonation and supports every major bodily function. It is the undisputed healthiest choice.
LaCroix is an excellent and healthy alternative to sugary drinks like soda, juice, or sweetened iced teas. For those struggling to consume enough plain water, the added flavor and fizz can be a great incentive to stay properly hydrated. It is also a calorie-free way to satisfy a craving for a carbonated beverage.
Ultimately, the choice depends on your personal health needs and preferences. While plain water is technically healthier due to its complete lack of additives, the health implications of LaCroix are so minor that it can be considered a very close second, and a far superior option to other carbonated drinks.
Conclusion: Choosing the Right Hydration for You
When comparing LaCroix and water, the former is not healthier than the latter. Plain water is the gold standard for hydration, free from any potential drawbacks. However, LaCroix remains a highly beneficial alternative to sugary soft drinks, providing a flavorful, zero-calorie, zero-sugar option that promotes adequate fluid intake for those who find plain water boring. For most people, incorporating LaCroix into their beverage routine is a perfectly healthy choice, as long as they are mindful of potential dental and digestive sensitivities and continue to prioritize plain water as their primary source of hydration. For the purest and most essential hydration, plain water is still king.
