Sharon, I dont think that an enzyme is required for phosphorous to appear in the blood, raising the pH and causing calcium to be pulled from the bones. The phosphorous and calcium complex is then expelled in the urine. See text and link below.
Regards Ivan. THE CALCIUM DEFICIENCY MYTH When asked about the causes of osteoporosis, most people will chime in with "Lack of calcium". This idea is reinforced on a daily basis as women are reminded to drink their three glasses of milk a day and take their calcium supplements. Even young, healthy, non-osteoporotic women are paranoid about potential bone loss and take measures to shore up their bone strength with plenty of calcium. Fear of insufficient calcium has become a national obsession. Is there really a national calcium deficit? Since bone is largely composed of calcium, it might appear logical to link calcium intake with bone health. Western women are now encouraged to consume at least 1,000 to 1,500 mg of calcium daily. It is curious, however, when cross-cultural data clearly shows that in less-developed countries-where people consume little or no dairy products and ingest less total calcium-there are much lower rates of osteoporosis.33 The Bantu of Africa have the lowest rates of osteoporosis of any culture, yet they consume from 175 to 476 mg of calcium daily. The Japanese average about 540 mg daily, but the early postmenopausal spinal fractures so common in the West are almost unheard of in Japan. Overall, their spinal fracture rate is one-half that of the US. All this is true, even though the Japanese have one of the longest life spans of any population. Studies of populations in China, Gambia, Ceylon, Surinam, Peru and other cultures all report similar findings of low calcium intake and low osteoporosis rates.34 Anthropologist Stanley Garn, who studied bone loss over a 50-year period in people in North and Central America, failed to find a link between calcium intake and bone loss.35 While it is agreed upon that adequate calcium is absolutely necessary for development and maintenance of healthy bones, there is no one standard ideal calcium intake. It is also obvious from these studies that high calcium intake is not necessary for healthy bones. There is certainly a problem with bone health in Western cultures. However, other vital factors that determine the complex process of healthy bones must be understood. Bones are affected by: the intake of other bone-building nutrients; consumption of potentially bone-damaging substances like excess protein, salt, saturated fat and sugar; the use of some drugs, alcohol, caffeine and tobacco; the level of physical exercise; exposure to sunlight and environmental toxins; the impact of stress; the removal of the ovaries and uterus; and many factors that limit endocrine gland functioning. There are at least 18 key bone-building nutrients essential for optimum bone health. If one's diet is low in any of these nutrients, the bones will suffer. They include phosphorus, magnesium, manganese, zinc, copper, boron, silica, fluorine, vitamins A, C, D, B6, B12, K, folic acid, essential fatty acids and protein. The body uses minerals only when they are in proper balance. For example, girls who consume diets high in meat, soft drinks and processed foods which have high levels of phosphorus have been found to have an alarming loss of bone mass.36 Too high a ratio of phosphorus in relationship to calcium will cause calcium to be pulled out of the bones in an attempt to compensate. Scientific evidence shows unequivocally that, by themselves, calcium supplements just don't work.37 And contrary to popular thought, calcium supplementation does not reduce the risk of fracture. There is now evidence that a high calcium supplement level is actually associated with a 50 per cent increase in the risk of fracture.38 However, as yet, there remains no proof that increasing the calcium intake with supplements or diet after menopause prevents fractures. In fact, several studies indicate that it doesn't really appear to lower the incidence of fractures at all. In Science (August 1978) it was stated the "link between calcium and osteoporosis was made on insufficient grounds" and that the advertisers were way out ahead of the scientific evidence. But a diet rich in calcium in early childhood and pre-menopausal years does build stronger bones, reducing risk of thin bones after menopause. The worst calcium supplements are bone meal, oyster shell and dolomite because they cannot be efficiently absorbed and may contain lead. Excessive calcium intake also leads to constipation and, more worrisome, kidney stones and calcification of the joints. The most effective form of supplementation is hydroxyapatite (especially if it is formulated with boron). This is the most natural of all calcium supplements and a complete bone food.39 And what about dairy foods for bones? Dr Michael Colgan, a well-known researcher in nutrition, an author and the founder of the Colgan Institute in the US, has said: "The medical advice to drink milk to prevent osteoporosis is self-serving poppycock." After all we've been indoctrinated with, it's a shocking revelation to discover that dairy products contribute to bone loss. The countries that consume the highest amounts of dairy products also have the highest rates of osteoporosis; the non-dairy-consuming countries have the lowest osteoporosis rates. In the body's wisdom, the highest priority is to maintain the proper acid/alkali balance in the blood. A high protein diet of meat and dairy products poses a great osteoporosis risk because it makes the blood highly acidic. Calcium must then be extracted from the bones in order to restore proper balance. Since calcium in the blood is used by every cell in the body to maintain its integrity, the body will sacrifice calcium in the bone to maintain homeostasis in the blood. In a year-long study of 22 postmenopausal women, there was no significant improvement in calcium levels when their diets were supplemented daily with three 300 mL glasses of skim milk (equivalent to 1,500 mg of calcium). The authors stated this outcome was due to "the average 30% increase in protein intake during milk supplementation". Since skim milk contains almost double the protein of whole milk, it promotes an even greater rate of calcium excretion.40 In a recently published 12-year study of nearly 78,000 women it was concluded that milk consumption does not protect against hip or forearm fracture. Female milk-drinkers actually had a significantly increased risk of fracture, and teenage milk-drinking was not protective against osteoporosis.41 There are still other problems with dairy products. They contain antibiotics, oestrogen hormones, pesticides and an enzyme that is a known factor in breast cancer. In addition, another recent study revealed that lactose-intolerant women who drank milk were at greater risk of ovarian cancer and infertility.42 ---------------------------------------------------------------------- ------------- Further information at : http://www.panix.com/~paleodiet/losspts.txt ----- Original Message ----- From: Sharon L.
