Variation in the Mineral Content of Commercially Available Bottled Waters: Implications for Health and Disease
This is an interesting and informative webpage with content indicated by its title. Although the article is dated August 1998 the information is mostly of the 'timeless' kind, I'd say.
Extract:
"A wide variation exists in the mineral content of bottled waters that are commercially available in North America and Europe: magnesium content ranges from 0 to 126 mg per liter, sodium from 0 to 1,200 mg per liter, and calcium from 0 to 546 mg per liter. Evidence links magnesium deficiency to sudden death, excess sodium to hypertension, and calcium deficiency to osteoporosis. Drinking water that is high in magnesium and calcium and low in sodium will help individuals achieve the recommended daily allowances of these minerals. Because wide variations exist in the mineral contents of commercially available bottled waters, understanding the potential beneficial and harmful effects of these minerals will provide valuable information on which water to choose."
It's always a good idea to check the mineral levels by looking at the nutrition information on the label. And remember that for the body to utilise calcium effectively, it needs a sufficiency of vitamin D, some good sources of which are sunshine, oily fish, liver, cod liver oil and milk.
