In March of 1998, it was my privilege to hear Dr. Lee talk in Chicago. He was the Doctor who, since 1975 or so, had been the leader in attempts to design a more natural approach to menopause, and who developed the progesterone cream that made my own passage through that time bearable. A part of his presentation I found very interesting related to the effects of hormones on post-menopausal bone loss. First, he addressed what he considered the false promise of Fosamax, which was the newest medical approach to the problem. He told us that the drug belongs to a class of amino bi-phosphates related to disphosphenates, the same chemical used in cleaners to remove the ring around the bath tub caused by mineral deposits from our water. This drug acts by stopping the resorption of bone, and therefore leads to a temporary increase in bone mass. However, since it does not promote bone growth, after a five year period the body is left with only old, static bone, and hip fractures start to occur. The studies done by the actual manufacturers of the drug show a 0% gain of bone with Fosamax, a 1 to 2% gain with synthetic hormones (whether estrogens or progestins), and a 2% loss with placebo. What has to be taken into account, however, is not only the lack of permanent benefit from Fosamax, but the presence of far from pleasant side effects: these occur with frequency, and include aching bones, possible permanent, severe damage to the esophagus, and damage to the lining of the stomach. It is also hard on the kidneys, and recently evidence has been accruing that it is extremely harmful to the eyes. (New England Journal Medicine March 20, 2003;348(12):1187-8) See RESOURCES at botton. Research shows that even short-term use of oral alendronate (Fosamax) can increase the risk of osteonecrosis ( bone death) of the jaw as a complication of dental procedures. In 2002, the FDA approved a new drug, called FORTEO, for osteoporosis prevention, despite the fact that they do not know whether it will cause osteosarcoma (bone cancer) in humans as it has demonstrably done in animals. (http://www.drugs.com/forteo.html) Once again, WE are the guinea pigs that will produce millions for drug companies. Dr. Lee's point is that most women over 65 have adequate estrogen, which inhibits bone loss. All claims to the contrary, estrogen does not play a role in bone BUILDING, but only in clearing away old bone cells so that new ones can be formed. However, at the age of approximately 35, progesterone production virtually ceases, since it is only produced in significant amounts after ovulation while estrogen is produced during the entire menstrual cycle. Before age 35 is the age of peak bone production in women: after that, it declines. The presence of estrogen makes no difference: the absence of progesterone does.
Following up on the comment about estrogen, there can be no doubt that adding soy to one's diet is a very important step towards maintaining estrogen production, since it is high in phytoestrogens, as plant estrogen precursors have come to be called. Their effect on the body is still somewhat controversial, but many experts believe that they block excess estrogen when necessary, and supply it when it is deficient, thus providing the best of both worlds! Some may worry that increased intake of protein from soy could affect their bone density - worry no more: consider a study in the American Journal of Clinical Nutrition. 2002;75(4):773-779 on calcium and protein intake in elderly men and women, by Dawson-Hughes B, Harris SS, where the investigators set out to determine whether calcium (in the form of calcium citrate malate) and vitamin D supplements could affect the associations between protein intake and change in BMD in a group of elderly men and women. A total of 342 healthy men aged 65 years, who had previously taken part in a 3-year, randomized, placebo-controlled trial of calcium and vitamin D supplementation,[1] were included in the study. Associations between protein intake and change in BMD were examined. Protein intake was assessed on the basis of responses to a food frequency questionnaire. BMD was determined every 6 months using DXA measurements of the femoral neck, lumbar spine, and whole body.
I have noticed with relief that more and more Doctors are addressing the need for calcium supplementation in women, and Dr. Lee mentioned this trend also: but he was censorious about the fact that patients are recommended to take Tums: a truly ironic recommendation, since Tums is designed to suppress stomach acid, and calcium is very poorly absorbed unless sufficient stomach acid is present. HCL in the stomach and a proper acid environment there is also essential for keeping the body in proper pH balance. Lack of acid in the stomach often leads top too much acid in the body, which in turn leads to the withdrawal of minerals from the bones to correct and neutralize the problem. It is my hope that as studies showing the efficacy of natural approaches continue to come out, Doctors will feel comfortable suggesting protocols which are not only helpful, but also not harmful. Until then I will continue to use and recommend progesterone to build bone, the best absorbed calcium for bone structure, and Ipriflavone and/or soy foods to guard against bone resorption without inhibiting bone growth. In a recent study by Dawson Hughes, published in the American Journal of Clinical Nutrition(2000;72:745-750), they looked at the effect of starting supplementation with calcium and vitamin D, and then discontinuing the supplements. What they found was that for men, benefits gained were negated by the end of 2 years. For women, there was an immediate loss of benefit. What this means is that in order to protect yourself, you need not only to start increasing your calcium, but to continue taking it without cessation! This is very important, since the study showed a decrease in fractures, and increase in bone density coupled with a decrease of bone breakdown. At the moment, less than 1 in 10 American men or women meet the daily recommendations for calcium set by the National Academy of Sciences! (1200mg of calcium per day, and 400/600 i.u of D per day)
