What Are the Bad Chemicals in LaCroix? A Deeper Look at Ingredients

5 min read

In 2020, a Consumer Reports study detected low levels of per- and polyfluoroalkyl substances (PFAS), also known as 'forever chemicals,' in several sparkling water brands, including LaCroix. While these levels were low, the finding added to public questions about the beverage's ingredients and safety.

Quick Summary

Ingredient transparency and potential health effects in LaCroix have raised consumer questions, notably concerning 'natural flavors' and trace levels of PFAS detected in a 2020 report. Issues like dental erosion are also considered with excessive consumption.

Key Points

  • "Natural Flavors" are not Secretly Synthetic: Claims of synthetic chemicals in a 2018 lawsuit were debunked; the cited compounds (limonene, linalool) are derived from natural fruit and plant essences.

  • Low-Level PFAS Contamination Found: A 2020 Consumer Reports test detected low levels of PFAS "forever chemicals" in LaCroix, but the amounts were well below regulatory guidelines at the time.

  • Potential for Dental Erosion: The carbonic acid from carbonation makes sparkling water mildly acidic, posing a low-to-moderate risk of enamel erosion with frequent consumption.

  • Risk of Bloating and Gas: The carbon dioxide in the beverage can cause digestive discomfort, such as bloating and gas, for some individuals, particularly those with sensitive stomachs.

  • Still a Healthier Choice Than Sugary Soda: As a calorie-free, sugar-free, and artificial sweetener-free option, LaCroix remains a significantly healthier hydration choice than sugary or diet sodas.

  • BPA-Free Cans: The company has confirmed that its cans do not use BPA liners, addressing consumer concerns about the packaging.

The Controversy Surrounding 'Natural Flavors'

For many years, LaCroix has been at the center of a debate over its 'natural flavors,' a claim the company uses to market its sparkling water as a healthier alternative to soda. This marketing point was seriously challenged in a 2018 class-action lawsuit that alleged the beverage was not, in fact, 'all natural'.

The 2018 Lawsuit and Its Allegations

The lawsuit, filed by Beaumont Costales, claimed that LaCroix contained several synthetic chemical compounds, including limonene, linalool propionate, and linalool. The firm's statement drew significant attention by sensationalizing the claims, noting that linalool is 'used in cockroach insecticide'. The case sought to challenge the company's '100% natural' labeling. LaCroix's parent company, National Beverage Corp., vehemently denied the allegations, stating their flavors are derived from 'natural essence oils'.

Separating Fact from Fear

Following the lawsuit, food scientists and journalists clarified the claims. Experts noted that while the mentioned compounds can be synthesized, they are also found naturally in many foods, including fruits and herbs. For example, limonene is a major component of citrus peel oil, and linalool is present in over 60 different spices and plants. The lawsuit against National Beverage was later dismissed, but it brought to light the ambiguity of the term 'natural'.

The FDA's Vague Definition of "Natural"

The FDA's definition of 'natural flavor' is a key part of this controversy. According to the agency, natural flavors must be derived from a plant or animal source, but this broad definition does not require companies to disclose the specific chemical compounds or the methods used to extract and process them. This lack of transparency means that when consumers see 'natural flavors' on a LaCroix can, they are getting a proprietary blend that is not fully detailed. This is not a specific issue with LaCroix but rather a common industry practice for food and beverage companies.

Potential Health Concerns with LaCroix

Beyond the 'natural flavors' debate, other concerns about potential health effects have been raised, primarily related to the beverage's carbonation and potential for contamination.

Dental Erosion: Acidity and Enamel

Excessive consumption of any carbonated beverage, including LaCroix, can be problematic for dental health. The process of carbonation involves dissolving carbon dioxide gas in water, which produces a weak acid called carbonic acid. While this is not as damaging as the citric or phosphoric acid found in many sodas, the slightly lower pH of sparkling water can still lead to the slow erosion of tooth enamel over time, especially with frequent sipping throughout the day. Plain water, which has a neutral pH of 7, remains the best choice for protecting dental health.

The "Forever Chemicals" Scare: PFAS

A 2020 Consumer Reports test found that LaCroix, along with several other sparkling water brands, contained low levels of PFAS. PFAS, or per- and polyfluoroalkyl substances, are a group of synthetic chemicals that do not break down in the environment or the body. High exposure to some PFAS is linked to potential health issues, including higher cholesterol, immune system problems, and increased cancer risk. However, it is crucial to note the following:

  • The levels detected in LaCroix were low (between 1.1 and 2.24 PPT) and well within the EPA's voluntary limits at the time.
  • The presence of PFAS is not exclusive to LaCroix but is a widespread water contamination issue.
  • LaCroix is generally seen as a safer alternative to other beverages with higher contaminant risks, but the findings highlight broader water quality concerns.

Digestive Issues: Bloating and Gas

The carbonation in sparkling water can introduce excess gas into the gastrointestinal system. For some people, particularly those with sensitive stomachs or conditions like GERD, this can cause discomfort, including bloating, belching, and gas. While not a health hazard, it can be an unwelcome side effect for regular consumers.

Is LaCroix a Healthy Alternative? A Comparative Look

For many, LaCroix is an easy way to cut down on sugary drinks without sacrificing flavor. Below is a comparison of LaCroix with other common beverages:

Feature LaCroix Sugary Soda Diet Soda Plain Water
Calories 0 High 0 0
Sugar 0 High 0 0
Artificial Sweeteners 0 0 Present 0
Sodium 0 Often contains some Often contains some 0
Acidity (pH) Mildly Acidic Very Acidic Slightly Acidic Neutral (7)
Dental Risk Low-Moderate High Moderate None
PFAS Risk Low (as detected in 2020) Varies by brand and source Varies by brand and source Varies by source

Other Reported Side Effects and Claims

  • Bloating and Gas: As previously mentioned, the dissolved CO2 can cause digestive discomfort for some individuals.
  • GERD Exacerbation: The acidity in carbonated beverages may trigger or worsen heartburn symptoms for those with gastroesophageal reflux disease.
  • BPA-Free Cans: The company states that all LaCroix beverages are produced in cans without BPA liners, addressing a common consumer concern about packaging.
  • Hydration: Despite its carbonation, LaCroix is still primarily water and can contribute to overall hydration, especially as a replacement for less healthy beverages.

The Verdict: A Balanced Perspective on LaCroix's "Bad Chemicals"

So, what are the bad chemicals in LaCroix? Based on the evidence, the notion of truly 'bad' or dangerous chemicals in LaCroix is largely unfounded and rooted in misinterpretations of the 2018 lawsuit. The compounds questioned were natural food essences, not synthetic poisons. The risk of dental erosion from its acidity is real but manageable with moderation and is significantly lower than that of sugary or diet sodas. The presence of trace PFAS chemicals is a widespread environmental issue, and the detected levels in LaCroix were low. For most people, LaCroix is a safe and healthier alternative to many other beverages. Moderation is key, especially for protecting your dental enamel. For more information on food safety standards, consult resources from the FDA.

A Simple Guide to Drinking LaCroix Safely

  • Limit your intake: Stick to a couple of cans per day to minimize the risk of dental erosion from the mild acidity.
  • Consider plain water: Mix in plain, still water between sparkling water cans to give your teeth a rest and ensure optimal hydration.
  • Use a straw: Drinking from a straw can help bypass direct contact with your teeth, reducing the potential for enamel damage.
  • Wait to brush: Avoid brushing your teeth immediately after drinking LaCroix. The acidic content temporarily softens enamel, and brushing right away can cause more damage. Wait at least 30 minutes.
  • Rinse with water: After finishing your can, swish your mouth with plain water to help neutralize the acid.

Conclusion: Navigating the Sparkling Water Conversation

The fear of 'bad chemicals' in LaCroix has been driven by a combination of sensationalized lawsuit claims and the ambiguity surrounding FDA labeling rules for 'natural flavors'. However, a closer look reveals that the main health considerations are not hidden toxins but rather the moderate risks associated with any carbonated, slightly acidic beverage. Concerns like dental erosion and bloating are legitimate for excessive consumption but should be weighed against the significant benefits of choosing a zero-sugar, zero-calorie alternative to sugary drinks. As with most things in nutrition, the key is balance and moderation. When consumed mindfully, LaCroix can be part of a healthy lifestyle, providing flavor and fizz without the health consequences of sugary beverages.
