evidence: Sparkling water is just plain water that’s had bubbles added to it (carbonation) using carbon dioxide under pressure.Along with the bubble-free still water you can get from your tap or a bottle, the Centers for Disease Control and Prevention (CDC) lists sparkling water as a healthier drink choice than soda and other high-sugar carbonated beverages. Does Water's pH Affect Your Health? The pH of our blood is like an acid-base balance gauge that keeps our body in stable equilibrium. It's a critical feedback loop that is tightly regulated and managed by our lungs and kidneys. A normal blood pH level is around 7.40. Certain diseases and health conditions can cause the blood to become too acidic (acidemia) or too alkaline (alkalemia). For example: Fluid loss (e.g., from vomiting and diarrhea) Kidney problems (e.g., chronic kidney disease, kidney failure) Lung disease (e.g., asthma, COPD, sleep apnea, infection) The pH of most bottled water is between 6.5-7.5. Kelly A. Reynolds, PhD, the Director of Community, Environment, and Policy for the Exposure Science and Risk Assessment Center (ESRAC) told Verywell that there is no scientific evidence that the pH of water has any bearing on our health.
