Is la croix sparkling water good for you

Say it ain’t so!

No one was more shook than our employees to see LaCroix under fire for using scary-sounding artificial ingredients. Yikes! We drink cases of the stuff every week. Are the rumors true? Is drinking LaCroix dangerous? We consult with HUM nutritionists to find out, but first…

About LaCroix

LaCroix has amassed a cult following in recent years, but did you know that the stuff has been around since 1981? Its humble origins start in the Midwest, and in fact, the name comes from the St. Croix River in Wisconsin. (That’s why “La Croy” is the correct pronunciation, not “La Croah”.)

The growing LaCroix obsession has two big factors. First, there’s the iconic look. LaCroix underwent a major rebranding in 2002. We can thank that project for the colorful labels we know and love today, which have since been adapted into swimsuits and even Halloween costumes.

But more importantly, sparkling water sales are rising overall in recent years as consumers become more and more health conscious. In fact, statistics show that the number of liters of soda sold is declining every year while the number of liters of sparkling water rises.

But is it really a healthy choice? You might recall that diet soda was once considered a healthy alternative only to get criticism later for its use of artificial sweeteners. Is sparkling water merely the next victim in a long line of fizzy drinks getting debunked?

The Controversy

LaCroix is facing a class-action lawsuit for misleading consumers with the all-natural claims on their labels. The lawsuit says that testing found artificial ingredients in their product including linalool – which is used in cockroach insecticide. YUCK.

But are things really as bad as they sound?

LaCroix says no. “LaCroix sparkling water is a healthy beverage. All ingredients in LaCroix are natural. Allegations that claim otherwise are false and trouble us much as they trouble you,” they say via Twitter.

Further digging shows that linalool does naturally occur in many plants. So while the use of it in cockroach insecticide sounds very scary, it’s perhaps no scarier than sodium used in plane deicing.

The Nutritionists’ Verdicts

To settle things, we checked in with HUM nutritionists to get their opinion.

“Linalool is actually terpene alcohol naturally occurring in a wide variety of flowering plants and spices like lavender, basil, cinnamon, lemongrass, cannabis, and more,” says Jessica Kelley, RDN. “It has a lemon aroma and is in many popular essential oils due to its relaxing and calming properties. Traditionally, it’s been used in Ayurvedic medicine to help treat anxiety and function as a sleep aid.”

For that reason, she says, “I personally wouldn’t turn down an ice-cold LaCroix if that’s all that’s available. If given the choice, I’d opt for Spindrift, but this is purely a personal taste preference. Spindrift contains real fruit juice and therefore calories, but I’m okay with that.” Still, she insists, drinking LaCroix isn’t going to harm you.

Sarah Greenfield, RDN, is less approving of the artificial ingredients. “While there isn’t great research to show that the compounds found in the product are bad, I typically steer clear of artificial chemicals in my foods. Looks like I’ll be going back to the plain, unflavored LaCroix and squeezing my own lemon.”

It looks like to each nutritionist, her own! Will you still sip on LaCroix?

La Croix (pronounced “La-Croy”), the delicious bubbly drink that’s become ubiquitous, is free of calories, added sugars, sweeteners, and sodium, and it’s got a very short ingredient list.

No junk, nothing to worry about… right?

Well, research on the general health effects of seltzers and sparkling waters like La Croix is scarce, but in the name of fizzy deliciousness, let’s examine the existing evidence.

Can Sparkling Water Hurt Your Stomach?

A (very) small study from 2002 suggested that carbonation may actually alleviate indigestion and constipation. More recently it has been suggested, though, that because carbonation can cause bloating, it may aggravate certain gastrointestinal issues.

Can Sparkling Water Weaken Your Bones?

A 2006 study featuring 2,500 male and female participants found that cola consumption was associated with with weakened hips in older women, but the researchers found no bone-density risk from other carbonated drinks.

In other words, carbonation wasn’t the issue — so this may be yet another reason to stay away from soda, but it’s not a red flag when it comes to sparkling waters like La Croix.

Can Sparkling Water Make You Gain Weight?

People started asking this question all over the internet again after a 2017 study asserted that carbonated beverages were associated with increased food consumption in its subjects — but its subjects were rats, so all the varying lifestyle factors that make up human health and fitness weren’t exactly factored in.

Does sparkling water even hydrate you like flat water?

In short, the answer seems to be: Yes.

Can Sparkling Water Harm Your Teeth?

Here’s where things get a little complicated, so stick with us. It’s a basic scientific fact that dissolving carbon dioxide into water (which is how seltzer gets its wonderful bubbles) puts carbonic acid in the water. If the dentists in the room are getting jumpy, it’s because they can already see where this is going.

A 2001 study published in the Journal of Oral Rehabilitation stated that “mineral waters appear to offer a safe alternative to more erosive acidic beverages.” However, a more recent study from 2007 said the opposite: The researchers soaked teeth in seltzer-filled containers for 30 minutes to measure the effect of sparkling water on enamel. They found the sparkling waters “demonstrated erosive potential similar to or greater than that of pure orange juice, an established erosive drink.”

In 2018, the Center for the Science in the Public Interest questioned those mysterious “flavors” in sparkling waters like La Croix — added flavors are chemicals that do not have to be disclosed, so there’s no way to know if they are likely to increase the acidity of a beverage. Their takeaway, though, was not to panic and start pouring all your Lime, Coconut, Pamplemousse, Mure Pepino La Croix down the drain:

As with dessert or the occasional cola, an occasional indulgence is no big deal — if you’re concerned, just don’t overdo it.
