The National Academy of Sciences (USA) and the associated National Research Council (USA) consists of distinguished scholars who provide independent advice on matters of science, technology, and medicine whenever called upon to do so by any department of the government of the USA. Members of the Academy have won more than 200 Nobel Prizes.
The National Academy of Sciences (USA) and the associated National Research Council (USA) have published evidence that groups of people demonstrate increased longevity (a low death rate) if they reside in areas of the United States that have relatively high levels of magnesium and bicarbonate in alkaline drinking water. In contrast, groups of people demonstrate decreased longevity (a high death rate) if they reside in areas of the United States that have relatively low levels of magnesium and bicarbonate in acidic drinking water. The differences in magnesium and bicarbonate levels and the differences in mortality in the two areas are striking. [See Feder GL (1981).
