Mineral water is also known as spring water because it comes from natural springs, which are places where moving underground water comes out of an opening in the land’s surface.
Mineral water can also be made artificially by adding salts to distilled water or aerating it with carbon dioxide to create more carbonation. However, mineral water is naturally carbonated to varying degrees.
The nutritional content of both natural and artificial mineral water varies greatly, but it typically has a high content of minerals like:
Calcium carbonate
Magnesium sulfate
Potassium
Sodium sulfate
It may also contain gases like:
Carbon dioxide
Hydrogen sulfide
Health Benefits
Due to its carbonation and mineral content, mineral water is known to provide multiple health benefits, including:
Contributing to Heart Health
In one study, post-menopausal women drank 1 liter of mineral water per day for two periods of two months each. The results showed that mineral water intake lowered the levels of bad (LDL) cholesterol and raised the levels of good (HDL) cholesterol.
Because high cholesterol increases your risk of heart disease and other conditions, mineral water helps keep your heart healthy and working properly.
In one 2004 study, researchers evaluated the effects of mineral water on subjects who all had borderline hypertension(high blood pressure) as well as low levels of calcium and magnesium. After four weeks of drinking mineral water, they noted a significant decrease in these people’s blood pressure.
Relieving Symptoms of Constipation
For people with dyspepsia (indigestion) and constipation, carbonated mineral water can decrease constipation as well as significantly improve its symptoms. As an added benefit, it can also improve gallbladder function.
Health Risks
Although there aren’t any health risks involved in drinking mineral water itself, drinking it out of unpurified or unsensitized plastic bottle may pose certain risks.
