The study investigates the differences in mineral content between tap water and bottled water in major Australian cities and its potential impact on kidney stone disease (KSD).
Tap water showed significant variability in mineral levels (like calcium and magnesium) across cities, often lower than those found in bottled sparkling water.
Finding higher mineral content in bottled sparkling water suggests it may be a better option for preventing calcium oxalate stones, aiding in patient counseling for KSD based on location and other factors.
