I was responding to Heidi's statement about the acid load specifically. I think it's relevant to *other* questions-- such as whether distilled water could leach minerals from the bones.

I would tend to think it is one of the additives (esp. in Coke and Pepsi, the two most common) but the researchers believed it has to do with the carbonation leading to belching. My take is that most of these things are based on statistical studies ... and folks who drink a lot of pop may be doing so because their stomach feels mildly upset, which may mean they have hypochloridia, lack of enzymes, gluten intolerance, or some other indigestion problem which WOULD lead to lack of bone density. Or maybe pop interferes with digestion. But I've never read anything that would indicate that they've done any experiments with pop and bone density, I think they are guessing ... the article below is what I've heard, that it seems to be a case of drinking pop instead of milk, in kids. So if you drink pop with fried dried anchovies you should be ok ... Anyway, if eating acids leaches bone, then we are in big trouble with these high-acid stomachs of ours, and kimchi should lead to osteoporosis. As for the carbonation ... our blood gets full of CO2 every time we exercise, or just sit for that matter, I can't see how a little bit more in the stomach would make much difference (unless it interfered with digestion ... ) http://www.obgyn.net/osteo/osteo.asp?page=/osteo/ate_0901 Q: I have been told by members of the health profession that drinking pop (more than 2 cans/day) increases the risk of osteoporosis, however nobody seems to be clear on the reason why. I've even had people tell me it was the carbonation or the caffeine. Why not drink coffee or tea? More reasonable mechanisms seem to be the phosphoric acid " leaching " calcium and/or drinking soda instead of milk. What is your opinion? A: If soda increases the risk of osteoporosis, it is probably because those who consume large amounts of soda may consume very little milk, hence are deficient in calcium intake. This is a growing and alarming trend especially among young children and adolescents. Many children seem to favor juice boxes, while teenagers seem to have replaced milk with Diet Coke and Mountain Dew. There is some data that excess amounts of caffeine may inhibit calcium absorption. That is not to say that coffee or tea are dangerous per se. Heidi Jean Quote Link to comment Share on other sites More sharing options...

Thanks for your reply Heidi. I wonder how mineral water gets to be carbonated in the first place? I found this from the S. African ministry of health: " naturally-carbonated natural mineral water " is a natural mineral water which, after possible treatment and re-incorporation of gas from the same source and packaged, taking into consideration normal technical tolerance, has the same content of carbon dioxide as it would if carbon dioxide were spontaneously and visibly given off under normal conditions of temperature and pressure; " I don't know if the rest of the world has the same standards, but from the few other links I looked at, it looks like the carbonation level in naturally sparkling mineral water is supposed to be the same as the original source. So, if carbonation per se causes osteoperosis, it would likely do so in those populations drinking naturally carbonated mineral waters direct from the springs, I'd guess. Then you have all those traditional societies that drank beer...although I bet some of those old time brews weren't as carbonated as modern ones. At least the traditional Tibetan rice beer I had in Nepal wasn't. Suze Fisher Lapdog Design, Inc. Web Design & Development http://members.bellatlantic.net/~vze3shjg Weston A.

I was thinking the same thing - that the large concentration of phosphoric acid in commercial soda pop is probably the problem due to it's imbalance with calcium. I can't imagine that any natural water has as much phosphoric acid as soda pop. As for Gerolsteiner, one site said it has 80 mgs Ca in 8 oz. (this must be my richest calcium source then!). I can't find a full ingredient list, although I believe I'd read it in the past. I doubt it has more phosphorous than Ca, or has so much more that it's imbalanced like soda pop.

No, I'm not sure I agree, but my concerns are theoretical since I have no hard numbers on hand. It's possible to swamp the body's absorption mechanisms, so it seems to me it could be possible to drink enough soda (leaving aside the sugar issue for the moment) that no amount of extra calcium could compensate. Certainly, though, most people's Ca intake is low enough to be problematic by itself. - Quote Link to comment Share on other sites More sharing options...

Right, good question. I don't know how absorbable it is. I'm sorry to hear about your mom - no wonder you haven't been around much lately. Let us know if you need anything.

Guest guest Posted September 5, 2004 Report Share Posted September 5, 2004 According to Sally Fallon (in her lecture) and several other sources that I have seen, it is the phosphoric acid that interferes with calcium absorption in the bone. I don't know the exact mechanism and I don't even know how much an effect it would have on a person with an otherwise healthy calcium level and calcium absorption mechanism but I would not be surprised to find it a major problem with people who are already calcium absorption compromised. As for the carbonation, it is unlikely to be any real problem. The acidity is unlikely to affect stomach acidity much and any carbon dioxide absorbed into the blood stream will be exhaled quickly. I can conjecture a situation where enough carbon dioxide / carbonic acid is absorbed by the blood stream to cause a sensation of shortness of breath (also noticed when carbon dioxide levels in the air are high) but this should pass very quickly. I might also add that a number of the healthy beverages promoted by the NT are naturally carbonated. I suspect that humans actually crave carbonation - perhaps because it is a key indicator of the presence of beneficial microbes (especially yeasts and lacto-bacilli). Personally, I gave up soda pop overnight after a 25 year long love-affair with it. It was to help my son out (he was asked to give it up for medical reasons) but, since then, my craving for soda is minimal. In addition, I make my own soda out of fruit juices. Not only does this hit that old carbonation craving when it crops up but it appears to be healthier for you (less sugars, more microbial nutrients).

I know that *I* sure do seem to crave carbonation. If I have a choice between a naturally carbonated water and non-carbonated water, 99% of the time I choose carbonated.

I have drunk water from " natural " sparkling springs, and it can be really sparkly! (also full of sulfur, in that case, it didn't taste very good!). I'm not sure what causes carbonation of underground springs. I would think it is that gas dissolves into the water under pressure, but in that case, how would it *only* be CO2? Why not dissolved nitrogen or oxygen? Also those " naturally carbonated " mineral waters were full of *minerals* so I'd think the net effect would be positive (unless the natural mineral was, say, arsenic). >Then you have all those traditional societies that drank beer...although I >bet some of those old time brews weren't as carbonated as modern ones. At >least the traditional Tibetan rice beer I had in Nepal wasn't. EZ Cap bottles were really, really hard to come by in Egyptian times ;--) When I brew my beer, it is fizzy even if it isn't capped, but not soooo fizzy. I think the first " really carbonated " beverage was champagne, made in thick glass bottles with cork held in place by wires, but that was super expensive and not a daily drink except for rich folks. But FWIW, if the bone test I got was correct, I have really dense bones and I drink plenty of carbonated beverages (I like the sparkling mineral waters too!). I agree with I really, really can't think of any reason why carbonation per se might be a problem. It wouldn't surprise me at all that the empty calorie softdrinks do cause problems, either because of all the sugar or the chemicals killing gut bacteria or who knows what else. > Heidi Jean Quote Link to comment Share on other sites More sharing options...

That was me. But I wasn't drinking the carbonated mineral water at the time, except on a rare ocassion. I started drinking it during my pepto bismol/fast/elimination diet which got rid of the bloating. But I should probably check and see if it might be bloating me nonetheless. I HAVE noticed a little bloat here and there, after several months without bloat (except a very slight stomach distension). Suze Fisher Lapdog Design, Inc.

But I think I'll try to master AEM first, which I just started last week. Suze, I too hesitated for many weeks before embarking on the path of natural sodas. Then I actually tried it and it turned out to be ridiculously easy. Here's what I do. 1) Buy a container of 100% fruit juice. " From concentrate " doesn't matter as much as " High Fructose Corn Syrup " . 2) Pour off ~1 to 2 inches to give yourself a little headroom for gas build-up (with LB fermentation you don't build up much of a head so 1 inch is fine. 3) Add ~1/8 tsp brewer's (not baker's) yeast or 2 tbs active whey. 4) Reset the lid loosely. 5) Let sit at room temperature for 3 days (70 to 80 degrees F) or longer if cooler. 6) Pour off into those beer bottles with the re-usable wired on caps (like Grolsch bottles) or leave in original container. The beer bottles are convenient because they can take the pressure and will let you build up a little fizz. 6) Cool in fridge or root cellar. 7) Drink within 1 to 2 weeks. I find that the LB-fermented sodas retain a bit more of the fruit flavor but I kind of enjoy the yeasty flavor of the Yeast-fermented sodas as well. On the other hand, the Yeast-fermented sodas produce a substance that makes me somewhat light-headed for ~15 minutes. Don't know what it is but, since the alcohol content can't be more than ~0.5%, I don't think it's alcohol. I also find it difficult to drink a whole bottle of the Yeast-fermented sodas at one sitting. I haven't tested enough LB-fermented sodas to know if the same holds true with them. Benefits 1) Most of the benefits of real fruit juice. 2) Reduced sugars. 3) Yeast or LB nutrients added to the soda. 4) The fizz builds up again after you re-close your bottle. Your sodas don't go flat. By the way, what is " AEM " ? Geoffrey Tolle > Quote Link to comment Share on other sites More sharing options...

I couldn't find data for the equilibrium of the conversion of sulfur dioxide to sulfurous/sulfuric acid and CO2 to carbonic acid in the book I looked at, but pollution with sulfur dioxide doesn't unambiguously make rain more acidic than CO2 does, so I'm assuming that's due to a lower concentration of the gas in the water.

Needless to say, with the high quality standards of the time, this cause more than a few deaths even in the classiest drinking establishments.

I did find a description of the experiment (it talks about using calcium too): http://wulfenite.fandm.edu/ScrubbersSummary%20-%20K.html .. Using pH paper, the student tests the pH of the water both before and after the reaction to observe the increase in acidity of the water brought about by the reaction between SO2(g) and H20(l) to produce sulfurous / sulfuric acid. The instructor may wish to provide a short discussion on how this reaction occurs and why an increase in acidity in the distilled water is observed.
