Love Melbourne (I lived in Sydney for some 25 years) - and pleased to see you on the list ;=) Glad you like Canada! It really is great, isn't it? After years away, I --- ooops, you *did* mean Canada, didn't you????? *LOL* Okay, just joking. Honest. I think the list owner is in the USA, and so are many (probably most) members ;=) Shall enjoy chatting to you. Best, Pat/Canada -- SANTBROWN townhounds/ http://www.angelfire.com/art/pendragon/ ---------- * " I will not let anyone walk through my mind with their dirty feet " - Gandhi * " The time will come when men such as I will look upon the murder of animals as they now look upon the murder of men " - Leonardo da Vinci ---------- Quote Link to comment Share on other sites More sharing options...
Guest guest Posted January 26, 2005 Report Share Posted January 26, 2005 Thanks for highlighting the Calcium question in your digest. As an older woman, I can relate to the problems that the " Metabolic Acidosis " can cause and will get back to you if I can find some ways of helping ourselves. 26 January 2005 13:35 Digest Number 581 There are 3 messages in this issue.

RE: calcium question " Maidawg " <maidawg ______________________ ______________________ Message: 1 Wed, 26 Jan 2005 05:19:55 -0500 " Maidawg " <maidawg RE: calcium question " Tom " tguidry said, " While I'm thinking on calcium, I've heard that cow's milk depletes calcium from your system because the casein protein in milk causes an acid condition in a humans stomach therefore the body attempts to neutralize it by pulling calcium (an alkaline) from the bones and tissues. With the result of just the opposite of what milk is advertised to produce... being strong bones and teeth. Is there any truth to this line of thinking ? " Here is one study reported by VRG (Vegetarian Resource Group): High-Protein Diet Depletes Bones Of Calcium UniSci - Daily University Science News A change in blood acidity caused by a high-protein diet accelerates osteoporosis by depleting bones of their calcium, say researchers at the University of Rochester. Their study, which appears in today's issue of the American Journal of Physiology, reveals for the first time how bones sacrifice themselves to compensate for the acid-producing foods we eat. " When we eat, we generate acid, " explains David A. Bushinsky, M.D., lead author of the study and professor of Medicine and of Pharmacology and Physiology at Strong Memorial Hospital at the University of Rochester. " These acids are ultimately excreted by the kidneys, but as we age, our kidneys don't function so well. If the kidneys can't keep up with our appetite, the bones step in and absorb the excess acid. That's good in the short term, but in the process the bones surrender calcium, phosphorus, sodium and everything they should be keeping to stay strong. " The process is called metabolic acidosis and it can become a problem for a middle-aged or older person whose kidneys are not working as efficiently as those of a younger person's. Not only does the bone trade off its calcium for the blood's acid, but the acid environment hinders osteoblasts, the cells that naturally rebuild damaged bone. " An older woman with kidney trouble should definitely watch how much protein she eats, " says Bushinsky. As much as 30 percent of post-menopausal white women, the group at greatest risk, have osteoporosis. Protein generates more acid than other foods, and the proteins in red meat generate more acid than those in fish or poultry. Vegetable proteins give rise to the least amount of acid. Though scientists have suspected that high levels of acid in the blood contribute to osteoporosis, this is the first time researchers have been able to confirm that the bones are actually deteriorating. Using a prototype machine called an " ion microprobe, " Bushinsky was able to zoom in and identify what made up each layer of a mouse bone. Up until now, researchers had to test the entire bone, and so would easily miss the loss of calcium that occurred only at the surface. The ion microprobe strips away layers of bone like a leaf-blower whisking away the top dry leaves while the wet ones stay on the lawn. Then it's just a matter of collecting the blown fragments and analyzing them. Bushinsky found that in just seven days, mice experiencing metabolic acidosis had measurable depletion of calcium in their femurs. " But the calcium depletion probably started just days, even hours after the blood became acidic, " he explains. Some medications and diseases can hinder the kidneys' ability to keep the blood pH at healthy levels. The two most common diseases that limit kidney function are hypertension and diabetes. This study is funded entirely by the National Institutes of Health. The ion microprobe was developed by Riccardo Levi-Setti, Ph.D., of the University of Chicago. - By Jonathan Sherwood [Contact: [3]Jonathan Sherwood] 3.

" (Joseph Keon's Whole Health, 1997) This point makes sense of the interesting trend that there is more osteoporosis in countries with higher intake of dairy (USA, Scandinavian countries) and less osteoporosis in countries where dairy has not traditionally been high (eg. some Asian countries). ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ from Maida Please sign my petition: http://www.thepetitionsite.com/takeaction/738171316 ______________________ ______________________ Message: 3 Wed, 26 Jan 2005 05:30:34 -0500 " Maidawg " <maidawg RE: calcium question Kirsten said, " My doctor told me to go back to using my cast iron cookware.
