Mineral water "works" by providing the body with essential minerals that can contribute to overall health, unlike regular drinking water, which is often processed and lacks the same mineral content. It delivers these minerals in a form that can be readily absorbed and utilized by the body.
Mineral Water vs. Regular Water
The key difference lies in its composition. Mineral water is sourced from naturally protected underground reservoirs and springs, where it acquires a variety of minerals as it flows through rocks. These minerals can include:
- Calcium: Important for bone health, muscle function, and nerve transmission.
- Magnesium: Essential for energy production, muscle and nerve function, and blood sugar control.
- Potassium: Helps regulate blood pressure, fluid balance, and muscle contractions.
- Sodium: Plays a role in fluid balance, nerve function, and muscle contractions. (However, high sodium intake can be detrimental for some people)
- Bicarbonates: Can help neutralize stomach acid and improve digestion.
Potential Health Benefits
While not a replacement for a balanced diet and a healthy lifestyle, mineral water can contribute to the following:
- Improved Bone Health: The calcium content in mineral water can contribute to maintaining bone density and reducing the risk of osteoporosis.
- Regulation of Blood Pressure: Some mineral waters are rich in magnesium and potassium, both of which can help regulate blood pressure levels.
- Improved Digestion: Bicarbonates found in certain mineral waters can help neutralize stomach acid and alleviate indigestion.
- Electrolyte Replenishment: Mineral water can help replenish electrolytes lost through sweat during exercise or other physical activities.
How Minerals are Absorbed
The minerals in mineral water are typically in an ionic form, which makes them easier for the body to absorb compared to minerals found in solid foods. The absorption process occurs primarily in the small intestine, where minerals are transported across the intestinal lining into the bloodstream.
Important Considerations
- Sodium Content: Some mineral waters can be high in sodium. Individuals with high blood pressure or those sensitive to sodium should choose low-sodium options.
- Individual Needs: The specific minerals and their concentrations in mineral water vary depending on the source. It is essential to choose a mineral water that aligns with individual health needs and dietary requirements.
- Overall Diet: Mineral water should be considered a supplement to a healthy diet, not a replacement for it.
