even orange juice to obtain this essential mineral, but it can also be found in our water supply.
The human body needs calcium to develop strong teeth and bones. With that, calcium can combat osteoporosis and other bone disorders. It also helps in regulating nerve transmission, blood coagulation, and muscle contraction.
Calcium intake through water sources is shown to protect against death from acute myocardial infarction (heart disease), especially in women. It also protects against rectal and gastric cancers.
Sodium
Sodium naturally occurs in water supplies in varying amounts due to underground salt deposits and sea water. It is also added to water supplies in some areas to make it "soft" (or through home water softeners), and used for water purification in the form of sodium hypochlorite.
Necessary for transporting nutrients throughout the body and balancing fluid levels, sodium is best known for its negative effects—namely raising blood pressure. So, those with high blood pressure may want to avoid water with high levels of sodium. However, in moderate amounts (under 3000 mg daily), sodium is perfectly safe.
Fluoride
There has been some controversy about fluoride being added to our water, more can be read about this debate.
While not absolutely necessary, fluoride is proven to protect against cavities when consumed in moderate amounts (under 4 mg/L). Fluoride is partially responsible for the rapid decline in tooth decay seen in the United States since the mid-1980s.
Special care should be taken when fluoride is ingested by children—levels over 2 mg/L can damage developing adult teeth before they break through the gums.
Most water systems add fluoride to their water supplies, but not all; check with your local provider for additive levels in your area.
