Is LaCroix Sparkling Water Bad For You?



Short answer

By itself, LaCroix sparkling water is not bad for you. However, there are some controversial yet noteworthy side effects of carbonated water and a certain concern towards LaCroix’s aluminum cans.

Long answer

Amazingly enough, this beverage has only two listed ingredients: carbonated water and natural flavor. They use absolutely no artificial flavors, no sweeteners or salts and they are a 0 calorie drink. Even most of their competitors can’t beat that. But still, some are skeptical that this drink is too good to be true.

One disappointment is that LaCroix’s aluminum cans are not bisphenol A (BPA) free, which they admit on their website. BPA is an industrial chemical that is coated on the inside most metal cans for food and drinks. Although more research is needed to determine the harmful side effects of this chemical, we should try to avoid buying products that contain BPA. The FDA has expressed their concern for potential effects on behavior, the brain, prostate glands in fetuses, infants, and young children.  

Fortunately, LaCroix sells their sparkling water in BPA-free glass bottles, but currently only in areas of Wisconsin and Illinois.

The other worry consumers have is about the carbonated water. Some say that carbonated water causes tooth decay, calcium loss in bones, IBS, and weight gain. Let’s examine the facts and research.

Sparkling water (bubbly, fizzy water) is produced when adding in pressurized carbon dioxide. This forms a weak carbonic acid. When combined with acidic flavorings such as lemon, sparkling water may be corrosive to tooth enamel, over a long period of time.

Soda, however, is a far more damaging fizzy drink than LaCroix, and not only for its acidity. Sodas contain phosphorus, which unlike sparkling water, can decrease the amount of calcium in the body via the kidneys.

Sparkling water is not a cause of irritable bowel syndrome (IBS), but if you experience discomfort such as bloating and gas, it’s best not to drink it.

What are the benefits of carbonation? A study was conducted with patients that had periodic constipation or dyspepsia, and after 15 days of drinking sparkling water, their conditions improved. Fizzy water also makes you feel fuller, which can help prevent overeating.
