Dreamer, unfortunately a lot of people aren't getting enough minerals in their body through their diet, especially with how exhausted the soils most of our food grows in are becoming, and how unnatural much of the food is... In these cases I don't see why distilled would be better than spring water with a good/safe mineral profile.
There actually is some reason to think that it could leach minerals from the body. From what I'm reading it looks like distilled water is more difficult to contain/put through pipes because it leaches so much into itself. If true this would be another negative for people who are already lacking enough dietary minerals to begin with.
Our bodies never consumed distilled water for the millions of years we've been evolving here, which probably has something to do with why in general it tastes worse to people. I hardly think its the only one fit for human consumption but in cases where only tap water or low quality spring water is available, and ones diet provides plenty of minerals, it might be the best option.
This thread piqued my interest so i rummaged around a bit on the web. Here is a long report on distilled water and the possible negative health affects, from the world health organization. I haven't read through the whole thing yet but its interesting so far. (Infund this one touches on homeostasis, as you mentioned)
http://www.who.int/water.../dwq/nutrientschap12.pdfHere is a general summary of some studies on this topic, found on another site. I haven't read the studies though myself so take it with a grain of salt. Hopefully they're not quite as harsh as they seem to imply, but its something to look into:
The following is from
here"Why is demineralised water not suitable for consumption?
There are three evident reasons:
-Demineralised water is highly aggressive.
Its distribution through pipes and storage tanks is not possible because the aggressive water would leach metals and other materials from the pipes and other plumbing materials.
-Demineralised water has poor taste and thirst-quenching characteristics.
This is again due to its lack of minerals.
-Demineralised water has been proven to have adverse health effects for humans, due to the deficiency of certain constituents. This is further documented in the following paragraph.
What supports this theory?
There are a number of studies, conducted by health professionals in different parts of the world, which support the three statements above. Here is an example of some of these studies and the resulting conclusions:
Rahmmanin et al, 1989. Study conducted on rats. Conclusions: distilled water caused decreased secretion of tri-iodothyronine and aldosterone, increased secretion of cortisol, morphological changes in the kidneys (including a more pronounced atrophy of glomeruli), swollen vascular endothelium limiting the blood flow and reduced skeletal ossification in fetuses.
Studies conducted on human volunteers by the WHO, 1980. Conclusions: low mineral water consumption increased diuresis (almost by 20%, on average), body water volume and serum sodium concentrations, decreased serum potassium concentration, increased sodium elimination.
Robbins and Sly, 1981. Study conducted in patients who received balanced intravenous nutrition diluted with distilled water. Conclusion: The intake of low mineral water is presumed to be responsible for an increased elimination of minerals from the body.
Study conducted by Basnyat et al, 2000. Conclusion: Ingestion of several liters of low-mineral water following intense physical efforts may cause severe acute damage, such as hyponatremic shock or delirium.
Epidemiological studies by Sauvant and Pepin 2002; Donato et al. 2003; Monarca et al. 2003; Nardi et al. 2003. Conclusion: Soft water and water low in magnesium is associated with increased morbidity and mortality from cardiovascular disease.
Study conducted by Verd Vallespir et al.1992. Conclusion: Intake of water low in calcium is associated with higher risk of fracture in children.
Jacqmin et al.1994. Conclusion: Intake of water low in calcium is associated with certain neurodegenerative diseases.
Yang et al. 1997, 1998, 2002. Conclusion: Intake of water low in calcium is associated with pre-term birth, low weight at birth and some types of cancer.
…and a very long etcetera of properly conducted experiments, which demonstrate what the World Health Organization is also claiming:
The WHO published in its latest report available (2004), that it has been adequately demonstrated that consuming water of low mineral content has a negative effect on homeostasis mechanisms, compromising the mineral and water metabolism in the body."
