Is La Croix as Hydrating as Water?

While we know that all fluids count towards your overall hydration status, are sparkling water beverages like La Croix just as hydrating as plain water? One study investigating the potential of different beverages on hydration status found that when corrected for actual water content, water and sparkling water had similar hydration capacities, both ranking at a 1 on their hydration scale (5). This means that as far as hydration goes, La Croix can be a great option to help meet your daily fluid needs.

Carbonated Beverages and Chronic Disease Risk

Consumption of traditional sugar-sweetened carbonated drinks, such as soda, has been long associated with an increased risk of chronic disease worldwide (1). But what about sparkling water that is free from added sugars? The American Heart Association conducted a review of the cardiometabolic effects of low-calorie sweetened beverages. They concluded that sugar-free carbonated beverages can help reduce sugar intake, which has a beneficial effect on chronic disease risk compared to traditional soda.

Furthermore, they noted that while soda containing non-sugar sweeteners such as aspartame can help reduce sugar intake, consuming unsweetened alternatives such as carbonated water or plain water is ideal (2). This means that sugar-free sparkling water beverages are a healthier alternative to traditional soda for those looking for a flavored carbonated drink.

Carbonated Beverages and Tooth Decay

Carbonated beverages such as traditional soft drinks have long been associated with negatively affecting oral health, but what about sugar-free varieties such as La Croix sparkling water? One study investigating the effect of various beverages on tooth enamel found that flavored carbonated water beverages produce significantly more erosion to enamel compared to plain water. Researchers attributed the effects on enamel to the carbonated beverages being more acidic than plain water. Compared to traditional soda, however, sugar-free carbonated water produced less erosion to the enamel (4).

Is La Croix Bad For You? Bottomline

In short, no. La Croix contributes to your daily hydration needs without providing a source of added sugar. It is an excellent option for those seeking an alternative beverage to traditional soda or other sweetened drinks. However, even sugar-free carbonated drinks can negatively impact tooth enamel if consumed frequently. Aim to meet your daily fluid needs with mostly water and enjoy unsweetened carbonated beverages such as La Croix in moderation.
