Drinking one to two cans of LaCroix daily is generally considered safe and moderate intake, according to nutrition experts. So, is it okay to drink 2 LaCroix a day, and what are the specific health considerations?

Quick Summary

Consuming two LaCroix cans daily is usually safe, though dental enamel erosion and digestive discomfort are potential concerns. This offers a low-calorie alternative to sugary sodas.

Key Points

Moderation is key: Most experts agree that drinking one to two cans of LaCroix daily is a moderate and safe consumption level.
Potential dental risk: Due to its mild acidity, especially in citrus-flavored varieties, prolonged or excessive consumption can risk enamel erosion, though less so than soda.
Hydration benefits: LaCroix is just as hydrating as plain water and can be an excellent calorie-free alternative to sugary drinks to help meet daily fluid intake.
Digestive side effects: Some individuals may experience bloating or gas from the carbonation; if you have sensitive digestion or GERD, it's wise to monitor your intake.
Mitigate risks: Simple habits like drinking with a straw, rinsing with water after, and not sipping throughout the day can protect your teeth.
Safe alternative: As a zero-calorie, zero-sugar option, LaCroix is a much healthier choice than sodas and other sweetened beverages.

Understanding LaCroix's Ingredients and Impact

LaCroix, a well-known sparkling water, includes carbonated water and natural flavors. It has no added sugars, artificial sweeteners, or calories, making it a good soda alternative. The carbonation and added flavors introduce mild acidity that can have an impact on health with frequent consumption.

The Effect on Dental Health

A potential downside of sparkling water is the effect on tooth enamel. Infusing carbon dioxide into water creates carbonic acid, which is a weak acid. For flavored varieties, citric or other acids from the fruit essences further increase acidity. Enamel erosion is a risk when the pH level is consistently low.

Plain sparkling water has a pH around 5-6, which is less acidic than soda, with a pH of 2-3.
Flavored versions, particularly citrus ones, can be more acidic, increasing the risk of enamel wear.
The risk factor isn't just the acidity, but the frequency and duration of exposure. Frequent consumption over time can be worse than drinking it all at once.

To mitigate dental risk, dentists recommend using a straw, rinsing the mouth with water after drinking, and waiting at least 30 minutes before brushing.

Potential Digestive Effects

For many, two cans of LaCroix a day will not cause negative digestive side effects. Some studies suggest that carbonated water can aid digestion and relieve constipation. The bubbles can also promote a feeling of fullness, which may assist with weight management.

However, for individuals with sensitive gastrointestinal systems or conditions like irritable bowel syndrome (IBS) or gastroesophageal reflux disease (GERD), the carbonation can be an irritant.

Bloating and Gas: The carbon dioxide gas in sparkling water can cause bloating and gas in some people.
Acid Reflux: Carbonation can increase pressure in the stomach, potentially leading to belching and triggering acid reflux symptoms.
Listening to Your Body: Increased discomfort could mean scaling back intake. Alternating between still and sparkling water can help maintain proper hydration while minimizing irritation.

Hydration and Overall Health Benefits

LaCroix is water with carbonation and natural flavors. It is just as hydrating as regular still water. For many, the taste and texture make it easier to meet daily fluid intake goals, especially as a replacement for sugary beverages. Staying hydrated is crucial for overall health, supporting cognitive function, and proper bodily processes. Switching from sugary sodas to LaCroix can reduce daily calorie and sugar consumption, which is beneficial for weight management and metabolic health.

LaCroix vs. Other Beverages: A Comparison

To put the risks and benefits into perspective, it's helpful to compare two cans of LaCroix with other common beverages.

Added Sugars	0	~70g+	0
Artificial Sweeteners	0	Often present (diet soda)	0
Sodium	0	Varies, can be present	Varies
Dental Acidity	Mildly acidic (higher in citrus)	Highly acidic	Neutral pH 7
Hydration	Excellent	Poor (due to sugar/caffeine)	Excellent
Digestive Issues	Potential for bloating/gas for sensitive individuals	Potential for gas, indigestion, and high-sugar-related issues	Very unlikely

Safe Consumption Practices for LaCroix

If you enjoy drinking LaCroix, there are simple ways to ensure your habit remains healthy. Moderation is key, and incorporating these practices can make all the difference.

Limit to meals: Drink your sparkling water with a meal. Chewing increases saliva production, which helps to neutralize the acid in your mouth.
Use a straw: A straw directs the liquid past your teeth, reducing prolonged acid exposure to enamel.
Follow with still water: Rinse your mouth with plain water after enjoying a sparkling beverage to wash away any residual acid.
Listen to your body: If you experience bloating, gas, or acid reflux, consider reducing your intake or alternating with still water.

Conclusion: Is 2 Cans of LaCroix a Day Okay?

For most healthy individuals, drinking two cans of LaCroix a day is perfectly okay and presents minimal health risks. It is a far healthier alternative to sugary soft drinks and can effectively contribute to your daily hydration goals. The main points of caution relate to dental health, particularly for flavored versions, and potential digestive discomfort for sensitive stomachs. By practicing moderation and taking simple preventative measures like rinsing your mouth, you can continue to enjoy your LaCroix fix without concern.
