While premium bottled water boasts exotic origins and special properties, experts say its true value lies more in taste and experience than superior hydration or health benefits.
The bottled water market has evolved significantly, with brands differentiating themselves through claims of glacial, volcanic, spring, mineral, and alkaline sources. These waters can command high prices, with some selling for over $100 a bottle. While water can indeed vary in mineral content, which affects taste, marketing often suggests that expensive, pure, or alkaline waters are inherently healthier, a notion that experts challenge.
Michael Mascha, founder of FineWaters, explains that the high cost of luxury water often stems from sourcing and transportation challenges rather than enhanced health properties. He suggests viewing high-end bottled water as part of a dining experience rather than a more effective hydration method. Hydration, according to Lucy Semerjian, an associate professor at the University of Sharjah, primarily depends on consuming sufficient safe water to replace daily fluid loss, regardless of brand or origin.
Minerals do contribute to genuine differences in water taste and can offer minor nutritional contributions, such as calcium or magnesium. However, terms like "rich in minerals" or high Total Dissolved Solids (TDS) numbers don't automatically signify superior quality or health. Maria Abi Hanna, CEO of Food Label Maker, points out that these labels don't provide specific nutrient amounts. Similarly, alkaline water's higher pH isn't necessarily a health advantage, as the body tightly regulates its own pH balance.
The mineral content of water, however, can significantly alter its taste and mouthfeel. Low-mineral waters, like some iceberg or glacial varieties, tend to taste light and neutral. Conversely, waters with higher mineral concentrations can have a more pronounced flavor and heavier texture. While these taste differences are real, the leap to claiming superior health benefits is often driven by marketing rather than scientific evidence.
Concerns about packaging also arise. While premium brands often opt for glass, perceived as safer and more luxurious than plastic, studies suggest neither is entirely free from microplastic contamination. Research indicates that microplastics can be found in beverages regardless of packaging material, with sources ranging from plastic bottles themselves to metal caps on glass bottles and even the beverages' processing. Ultimately, the choice of bottled water often comes down to personal preference for taste and experience, with price not being a reliable indicator of health value.
