Is it healthy to drink distilled water instead of tap or bottled water? Please state your scientific sources.?

After reading this, I'll let you decide. Distilled or de-mineralized water is usually tap water that has been treated to remove nearly all minerals and sodium that occur naturally in water. People commonly believe that bottled water is "healthier" than tap water. Calcium (Ca) and magnesium (Mg), in particular, are important minerals we would want in our water. Death rates tend to be lower in areas with tap water containing higher levels of Ca and Mg. It has been shown that deficiencies in magnesium are capable of producing heart disturbances, including 215,000 fatal heart attacks in the U.S. each year, and as many as 20,000,000 fatal heart attacks worldwide. Few brands of bottled water offer a significant amount of minerals.
