The Wellness Revolution

Body Burden and the wellness Revolution

This Study—the latest indication that all of us carry a “body burden” caused by widespread chemical use in our society—shows the need for a system that relies on organic agriculture and alternative pest controls. The constant exposure to toxics we experience today is a major cause of chronic illness, including cancer, birth defects or abnormal development, brain or nervous system damage, hormonal and reproductive imbalances, and impaired immunity, to name just a few.

Meanwhile, individuals should take advantage of the organic products available in health food stores, and the herbs and nutrients that support detoxification and the liver, the main organ of detoxification, as well as immunity—for example, silymarin, N-acetyl cysteine, calcium d-glucarate, folic acid, Reishi and shiitake mushroom, and turmeric. A healthy lifestyle and appropriate supplementation can offer some protection from societal pollution.

Subject: Strontium Bone Maker 60 VC - Strengthen Bones

Benefits

Helps maintain strong, healthy bones.*

In Vitro and Animal Studies

Strontium is a bone-seeking mineral incorporated by ionic substitution for calcium onto the crystal surface of bone.2 In the test-tube (in vitro), strontium inhibits the activity of osteoclasts, bone cells that break down bone, or “resorb” bone as part of the normal bone remodeling process.3 The effect of strontium, in the form of strontium ranelate (a salt of strontium and ranelic acid), was studied in monkeys over a six-month period. Strontium altered the remodeling of bone in the monkeys, resulting in decreased bone resorption with a concomitant maintenance of bone formation. A trend toward increased volume of osteoid, the organic matrix of bone, was observed, although this was not associated with defects in bone mineralization.4 In another animal study, monkeys fed strontium at high doses for six weeks showed a marked increase in bone strontium content. No harmful effects on bone mineral chemistry or structure occurred.5 At low doses, strontium has been shown to increase the number of bone forming sites in thighbones of adult rats, without adverse effects on the mineral content of bone or mineralization of the organic bone matrix.6 Strontium was shown to reverse bone loss induced by estrogen deficiency in rats.7

Clinical Trials

Human clinical trials have examined the effect of strontium on bone in postmenopausal women. In the dose-ranging (Phase 2) PREVOS trial, women in early menopause were administered strontium ranelate or a placebo for two years. Strontium ranelate was given at daily doses of 125 mg, 500 mg or 1 gram. (Total weight of compound; strontium plus ranelic acid). Compared to women in the placebo group, who lost bone, women on strontium at the 1 gram dose showed statistically significant increases in bone mineral density (BMD) of the hip, thigh and lumbar spine. Biochemical markers of bone formation, such as serum alkaline phosphatase, increased. No effect on markers of bone resorption was observed, leading to the conclusion that strontium ranelate, at the 1 gram daily dose, increased bone formation without decreasing bone resorption proportionally. It was concluded that 1 gram per day is the minimum effective daily dose of strontium ranelate in these women.8

In another Phase 2 trial (STRATOS trial), 353 postmenopausal women with osteoporosis, who had experienced at least one spinal fracture, took strontium ranelate for two years at daily doses of 500 mg, 1 gram or 2 grams. Women on the 2-gram dose showed a significantly greater increase in lumbar spine BMD than those on placebo. The number of subjects who had new spinal deformities was significantly reduced.9 As in the PREVOS trial, serum levels of alkaline phosphatase, a marker of bone formation, increased, while markers of bone resorption (breakdown) decreased. The overall conclusion is that the minimum effective daily dose of strontium ranelate (whole compound) is 1 gram in early postmenopausal non-osteoporotic women and 2 grams in postmenopausal women with osteoporosis.10

Phase 3 efficacy studies on strontium ranelate have been conducted on 1649 subjects in 12 countries. These studies began with an open-run (non-controlled study period in which subjects took calcium and vitamin D supplements to normalize their blood levels of these nutrients.11 Following this, two parallel groups were administered 2 grams daily of strontium ranelate or placebo for 3-years. The subjects continued to take calcium and vitamin D during the study. In subjects on strontium ranelate, BMD increased in the lumbar vertebrae by 14.4 percent and in the thighbone by 8.3 percent. The number and risk of vertebral fractures decreased.12

Safety

Suggested Use: Take two capsules daily. Calcium intake must also be adequate. Do not take this product with calcium supplements.

Strontium ranelate was well-tolerated in the trials discussed above. The incidence of adverse events in subjects on strontium ranelate was statistically equivalent to the placebo groups, and no negative effects on hematology and other biochemical parameters have been observed.

In view of the fact that subjects on the strontium trials also took calcium, and in some cases vitamin D, to maintain normal blood levels of these nutrients, it is important to ensure calcium and vitamin D intakes are adequate when supplementing with strontium. This is underscored by earlier research on animals suggesting that increasing the intake of strontium via diet may demineralize bone when calcium is deficient.13 In rats with chronic kidney failure, strontium has been shown to cause osteomalacia, a condition in which bone is softened due to lack of mineral content. For this reason, people on kidney dialysis should not use strontium supplements.14

Subject: PROGESTERONE AND OSTEOPOROSIS

PROGESTERONE AND OSTEOPOROSIS

At this writing, evidence points to the fact that natural progesterone may be even more effective in treating osteoporosis than estrogen replacement therapy. While this evidence is still in its initial stages, it is significant and must be considered. In 1981, Dr. John Lee conducted a landmark study evaluating the effectiveness of using natural progesterone for osteoporosis.20 His study indicated that it is the cessation of progesterone production in postmenopausal women which causes the development of osteoporosis. Contrary to current trends, progesterone replacement, not estrogen, in fact may be the answer to preventing and treating osteoporosis. Dr. Lee’s study has profound implications for all women.

In his practice, Dr. Lee applied a natural progesterone cream on one hundred postmenopausal women and eliminated their usual dose of oral Provera (a synthetic progestin). The majority of these women were in varying stages of osteoporosis. Each participant used the natural progesterone cream for several consecutive days each month over a period of three years. The results were dramatic, to say the least. In addition to preventing further height loss and eliminating aches and pains, the bone mineral density of the spine was preserved in 63 of the women. In other words, these women not only stopped the bone loss associated with osteoporosis but actually experienced an increase in bone mass which, in many cases was more dramatic than had been seen with other therapies. In addition, the incidence of bone fractures actually dropped to zero. Dr Lee’s study found that estrogen was not the panacea for bone density previously assumed. He discovered that the women who took estrogen in combination with the progesterone were not better off than those who took progesterone alone. What was even more impressive was discovering that osteoporosis is a reversible condition with progesterone therapy. Concerning the use of progesterone for osteoporosis, Dr. Lee writes:

. . . when my 40 year old housewives had become 60-year olds with osteoporosis and I learned of transdermal natural progesterone (being sold as a skin moisturizer), I started adding it to my therapeutic regimen for osteoporosis, at first only to those for whom estrogen was contraindicated. To my surprise, serial bone mineral density tests showed a significant rise without a hint of side effects. With this obvious success, my use of natural progesterone spread to osteoporosis patients who were not doing all that well on estrogen alone. Again, it proved successful.21

Apparently, women who had the lowest bone densities experienced the greatest increases, implying that age and the progression of the diseases does not affect the beneficial therapeutic action of natural progesterone.

This study is profoundly significant in that it strongly suggests that women who take estrogen to prevent or treat osteoporosis may be better off using natural progesterone. As a result of Lee’s findings, several physicians began to use natural progesterone cream for their pre- and postmenopausal patients.

The most striking implication of Dr. Lee’s work with natural progesterone is that contrary to current medical opinion, osteoporosis may be more a manifestation of a progesterone deficiency than a lack of estrogen. In addition, the disease may be initiated long before menopause when estrogen levels are still high.22 Moreover, continued estrogen therapy for women with osteoporosis often caps out whereas progesterone therapy continually promotes the production of new bone.23 Dr. C. Norman Shealy, M.D. states: I believe that natural progesterone cream derived from wild yam extract should be used by almost every mature adult . . . The most common cause of death in elderly women is from the complications of fracture of the hip from osteoporosis. Such fractures are also remarkably common in men. I believe that progesterone cream could do more to preserve health and well-being in elderly people than all the drugs in the world.24

Subject: Pain - Post Op and Relaxation

Relaxation, Music Reduce Post-Op Pain. New research has found that relaxation and music, separately or together, significantly reduce patients' pain following major abdominal surgery. The study, published in the May issue of the journal Pain, found that these methods reduce pain more than pain medication alone. Led by Marion Good, PhD, RN, of Frances Payne Bolton School of Nursing, Case Western Reserve University, Cleveland, Ohio, the study is supported by the National Institute of Nursing Research (NINR), at the National Institutes of Health. "This is important news for the millions of Americans who undergo surgery and experience postoperative pain each year," said Dr. Patricia A. Grady, director of the NINR.

"Better pain management can reduce hospital stays and speed recovery, ultimately improving patients' quality of life." Dr. Good and her research team studied three groups of patients undergoing abdominal surgery. In addition to the usual pain medication, one group used a jaw relaxation technique, another group listened to music, and a third group received a combination of relaxation and music.

Findings revealed that, after surgery, the three treatment groups had significantly less pain than the control group, which received only pain medication. "Both medication and self-care methods which involve patient participation are needed for relief," said Dr. Good.

"These relaxation and music self-care methods provide more complete relief without the undesired side effects of some pain medications." The findings have important implications for the 23 million people who undergo surgery and experience postoperative pain annually in the United States. Pain can hamper recovery by heightening the body's response to the stress of surgery and increasing tissue breakdown, coagulation and fluid retention. Pain also interferes with appetite and sleep and can lead to complications that prolong hospitalization.

Dr. Good and her research staff worked with 500 patients aged 18-70, who were undergoing gynecological, gastrointestinal, exploratory or urinary surgery. Prior to surgery, those in the music, relaxation or combination groups practiced the techniques. The relaxation technique consisted of letting the lower jaw drop slightly, softening the lips, resting the tongue in the bottom of the mouth, and breathing slowly and rhythmically with a three-rhythm pattern of inhale, exhale and rest. Patients in the music group chose one of five kinds of soothing music--harp, piano, synthesizer, orchestral or slow jazz.

On the first and second days after surgery, all patients received morphine or Demerol for pain relief by pressing a button connected to their intravenous patient controlled analgesia pumps. The groups receiving the additional intervention used earphones to listen to music and relaxation tapes during walking and rest, while the control group did not. The research team measured the patients' pain before and after 15 minutes of bed rest and four times during walking to see if the sensation and distress of pain changed.

Dr. Good found that during these two days postsurgery the three treatment groups had significantly less pain than the control group during both walking and rest. "Patients can take more control of their postoperative pain using these self-care methods," says Dr. Good. "Nurses and physicians preparing patients for surgery and caring for them afterwards should encourage patients to use relaxation and music to enhance the effectiveness of pain medication and hasten recovery."

Dr. Good's findings have implications for future research into the effectiveness of self-care methods on other types of pain, including chronic pain, cancer pain, and pain of the critically ill.

Vitamin D Lack Linked to Hip Fracture. Vitamin D deficiency in post-menopausal women is associated with increased risk of hip fracture, according to investigators at Brigham and Women's Hospital in Boston, Mass. In a group of women with osteoporosis hospitalized for hip fracture, 50 percent were found to have a previously undetected vitamin D deficiency. In the control group, women who had not suffered a hip fracture but who were hospitalized for an elective hip replacement, only a very small percentage had vitamin D deficiency, although one-fourth of those women also had osteoporosis. These findings were reported in the April 28, 1999, issue of the Journal of the American Medical Association.

The study, conducted by Meryl S. LeBoff, MD; Lynn Kohlmeier, MD; Shelley Hurwitz, PhD; Jennifer Franklin, BA; John Wright, MD; and Julie Glowacki, PhD; of the Endocrine Hypertension Division, Department of Internal Medicine, and Department of Orthopedic Surgery, Brigham and Women's Hospital, Boston, was supported by grants from the National Institute on Aging (NIA) and the National Center for Research Resources (NCRR. These investigators studied women admitted to either Brigham and Women's Hospital or the New England Baptist Hospital, both in Boston, between January 1995 and June 1998.

A group of 98 postmenopausal women who normally reside in their own homes were chosen for the study. Women with bone deterioration from other causes were excluded from the study.

There were 30 women with hip fractures caused by osteoporosis and 68 hospitalized for elective joint replacement. Of these 68, 17 women also had osteoporosis as determined by the World Health Organization bone density criteria. All the participants answered questions regarding their lifestyle, reproductive history, calcium in their diet, and physical activity.

Bone mineral density of the spine, hip, and total body were measured by dual X-ray absorptiometry (DXA) technique, as was body composition. Blood chemistry and urinary calcium levels were analyzed. The two groups of women with osteoporosis did not differ significantly in either time since menopause or bone density in the spine or hip. They did, however, differ in total bone density.

The women admitted for a hip fracture had fewer hours of exercise than the control group. Fifty percent of the women with hip fractures were deficient in vitamin D, 36.7 percent had elevated parathyroid hormone (PTH) levels (a hormone which can stimulate loss of calcium from bone), and 81.8 percent had calcium in their urine, suggesting inappropriate calcium loss. Blood levels of calcium were lower in the women with hip fractures than in either elective group.

These researchers propose that vitamin D supplementation at the time of fracture may speed up recovery and reduce risk of fracture in the future. Current Dietary Reference Intake Guidelines contain a daily recommendation of 400 IU of vitamin D for people aged 51 through 70 and 600 IU for those over age 70.

"We know that a calcium-rich diet and regular weight-bearing exercise can help prevent osteoporosis. This new research suggests that an adequate intake of vitamin D, which the body uses to help absorb calcium, may help women to reduce their risk of hip fracture, even when osteoporosis is present," observed Dr. Evan C. Hadley, NIA Associate Director for geriatrics research.

"Osteoporosis leads to more than 300,000 hip fractures each year, causing pain, frequent disability, and costly hospitalizations or long-term care. "Prevention of such fractures would greatly improve the quality of life for many older women and men, as well as significantly reduce medical costs." The bones in the body often undergo rebuilding. Some cells, osteoclasts, dissolve older parts of the bones. Then, bone-building cells known as osteoblasts create new bone using calcium and phosphorus.

As people age, if osteoporosis develops, more bone is dissolved than is rebuilt, and the bones weaken and become prone to fracture. Also in many older persons, levels of vitamin D in the blood are low because they eat less or spend less time in the sun, which stimulates the body's own production of vitamin D.

Experts do not understand fully the causes of osteoporosis. However, they do know that lack of estrogen which accompanies menopause, diets low in calcium, and lack of exercise contribute to the problem. Eighty percent of older Americans who face the possibility of pain and debilitation from an osteoporosis-related fracture are women. One out of every two women and one in eight men over the age of 50 will have such a fracture sometime in the future. These fractures usually occur in the hip, wrist, and spine.

Sleep Apnea, Diabetes Link Found. Adults who suffer from obstructive sleep apnea are three times more likely to also have diabetes and more likely to suffer a stroke in the future, according to a new UCLA School of Dentistry/Department of Veterans Affairs study published today in the Journal of Oral and Maxillofacial Surgery. Sleep apnea, a serious condition marked by loud snoring, irregular breathing and interrupted oxygen intake, affects an estimated nine million Americans. The culprit? Carrying too many extra pounds.

"The blame falls squarely on excess weight gain," said Dr. Arthur H. Friedlander, associate professor of oral and maxillofacial surgery at the UCLA School of Dentistry and associate chief of staff at the Veterans Affairs Medical Center in Los Angeles. Surplus weight interferes with insulin's ability to propel sugars from digested food across the cell membrane, robbing the cells of needed carbohydrates. Diabetes results when glucose builds up in the bloodstream and can't be utilized by the body. Being overweight can also lead to obstructive sleep apnea, according to Friedlander.

"When people gain too much weight, fatty deposits build up along the throat and line the breathing passages," he explained. "The muscles in this region slacken during sleep, forcing the airway to narrow and often close altogether." Reclining on one's back magnifies the situation. "When an overweight person lies down and goes to sleep," Friedlander said, "gravity shoves the fat in the neck backwards. This blocks the airway and can bring breathing to a halt."

Friedlander tested the blood sugar of 54 randomly selected male veterans whom doctors had previously diagnosed with obstructive sleep apnea. He discovered that 17 of the 54 patients, or 31 percent, unknowingly suffered from adult-onset diabetes. Using the same sample, Friedlander also took panoramic X-rays of the men's necks and jaws. The X-rays indicated that 12 of the 54 patients, or 22 percent, revealed calcified plaques in the carotid artery leading to the brain.

These plaques block blood flow, significantly increasing patients' risk for stroke. Seven of the 12, or 58 percent, were also diagnosed with diabetes. In dramatic comparison, the 17 patients diagnosed with diabetes showed nearly twice the incidence of blockage. Seven of the 17 men, or 41 percent, had carotid plaques. Only five of the 54 patients who displayed plaques did not have also diabetes. If he conducted this study today, Friedlander notes, he would likely find a higher number of diabetic patients. After he completed the study in 1997, the American Diabetes Association lowered its definition for diabetes from 140 to 126 milligrams of sugar per deciliter of blood.

"This is the first time that science has uncovered a link between sleep apnea and diabetes," said Friedlander. "The data suggest that someone afflicted with both diabetes and sleep apnea is more likely to suffer a stroke in the future." "Persons going to the doctor for a sleep-apnea exam should request that their blood be screened for diabetes, especially if they are overweight," he cautioned. More than half of the individuals who develop diabetes as adults will need to modify their diet and take daily insulin in order to control the disease, he added.

Stress, Surgery May Increase CA Tumors. Stress and surgery may increase the growth of cancerous tumors by suppressing natural killer cell activity, says a Johns Hopkins researcher.

Malignancies and viral infections are in part controlled by the immune system's natural killer (NK) cells, a sub-population of white blood cells that seek out and kill certain tumor and virally infected cells. In a study using animal models, natural killer cell activity was suppressed by physical stress or surgery, resulting in a significant increase in tumor development.

These findings suggest that protective measures should be considered to prevent metastasis for patients undergoing surgery to remove a cancerous tumor, according to Gayle Page, D.N.Sc., R.N., associate professor and Independence Foundation chair at the Johns Hopkins School of Nursing. "Human studies have already found a connection between the level of NK activity and susceptibility to several different types of cancer," says Page, an author of the study.

"We sought to determine the importance of stress-induced suppression of NK activity and thus learn the effects of stress and surgery on tumor development. "Many patients undergo surgery to remove cancerous tumors that have the potential to spread. If our findings in rats can be generalized to such clinical settings, then these circumstances could increase tumor growth during or shortly after surgery." The research was conducted at Ohio State University College of Nursing and the Department of Psychology at UCLA, where Page held previous positions, and at Tel Aviv University.

Results of the study are published in the March issue of the International Journal of Cancer. In laboratory studies, Page and her colleagues subjected rats to either abdominal surgery or physical stress, and then inoculated them with cancer cells. In the rats that had undergone surgery, the researchers observed a 200 to 500 percent increase in the incidence of lung tumor cells, an early indicator of metastasis, compared with rats that had not received surgery.

The experiment also showed that stress increased lung tumor incidence and significantly increased the mortality in the animals inoculated with cancer cells. "Our results show that, under specific circumstances, resistance to tumor development is compromised by physical stress and surgical intervention," says Page.

"Because surgical procedures are life-saving and cannot be withheld, protective measures should be considered that will prevent suppression of the natural killer cell activity and additional tumor development. "Researchers do not yet know how to prevent surgery-induced immune suppression, but early animal studies have shown increased use of analgesia reduces the risk."

The study was funded by the National Institutes of Health, and the Chief Scientist of the Israeli Ministry of Health. Lead author was Shamgar Ben-Eliyahu, Ph.D., and other authors were Raz Yirmiya, Ph.D., and Guy Shakhar.

Subject: America's Most Wanted

America's Most Wanted

by Brian Amherst Energy Times, January 6, 2000

The United States eats well, a little too well, according to experts. Amply supplied with a large supply of high-calorie food, our diets might seem to be chock full of every conceivable nutrient. Well, to the question "Getting all the right vitamins, minerals and other nutrients?" the most appropriate answer seems to be "Not exactly." Eating a lot doesn't equal eating a lot of the most important vitamins and minerals. So, which vitamins and minerals are likely to show up in short supply in the typical American diet? Calcium certainly sits at the top of list. According to the most recent Continuing Survey of Food Intake by Individuals, which is conducted by the United States Department of Agriculture (USDA), women and girls age 12 and up are not consuming adequate calcium from their diet. Research reveals that about 1200 mg. day suffices for those over age 50 and 1000 mg a day should be adequate if you're between the ages of 19 and 50. Since strong bones are formed during "the first three decades of life," says Laura Bachrach, MD, of Since strong bones are formed during "the first three decades of life," says Laura Bachrach, MD, of Stanford University, ". . .osteoporosis is a pediatric disease." For long-range protection against that bone-weakening disease, kids should eat calcium-rich, low-fat dairy products and plenty of leafy greens (broccoli, cabbage, kale) as well as salmon (with bones), seafood and soy. But the calcium campaign does not end in early adulthood. Bone mass begins to deteriorate at about age 30. Menopausal hormonal changes can exacerbate bone brittleness. Medical conditions, including cancer, liver disease and intestinal disorders; prescription drugs; tobacco and alcohol indulgence; or a decline in activity, especially the weight-bearing kind, also jeopardize bone strength. According to the National Osteoporosis Foundation, about one in every two American women will break a bone after age 50 due to osteoporosis. That translates into about half a million fractured vertebrae and more than 300,000 shattered hips. Frequently, those breaks are life-threatening.

Crucial Calcium

The critical role of calcium in many body functions is perhaps the most extensively clinically documented among nutrients. Researchers in the Department of Medicine, Oregon Health Sciences University in Portland, reviewed epidemiological and clinical studies conducted over the past two years on the relationship between dietary calcium and blood pressure (J Am Coll Nutr October 1999: 398S-405S). "Nearly 20 years of investigation in this area has culminated in remarkable and compelling agreement in the data," the researchers report, "confirming the need for and benefit of regular consumption of the recommended daily levels of dietary calcium." Investigators at the State University of New York, Buffalo School of Dental Medicine, presented results of their studies of calcium and vitamin C and gum disease at the June 26, 1998 meeting of the International Association for Dental Research. Two separate inquiries revealed that people who consumed too little calcium as young adults, and those with low levels of vitamin C in their diets, appear to have nearly twice the risk of developing periodontal disease later in life than folks with higher dietary levels of either nutrient.

Calcium: Much Documented Researchers offer extensive evidence of calcium's benefits on many fronts: n Osteoporosis poses a threat to older men as well as women, according to Randi L. Wolf, PhD, research associate at the University of Pittsburgh Graduate School of Public Health. Dr. Wolf presented her award-winning study to an October 3, 1999 meeting of the American Society for Bone and Mineral Research. Dr. Wolf suggests that men increase their consumption of calcium, particularly after age 80, to avoid age-related declines in the amount of calcium absorbed. According to Dr. Wolf, "It appears that the hormonal form of vitamin D, which is the main regulator of intestinal calcium absorption, may have an important role. We are conducting more research to better understand the reasons for why calcium absorption declines with age in men." n Scientists at Tufts University in Boston did some earlier work on the calcium-vitamin D connection and reported it in the September 4, 1997 New England Journal of Medicine. Using the National Academy of Sciences (NAS) increased recommended daily intake of 1200 milligrams of calcium and 400 to 600 international units of vitamin D for people over 50, the Tufts researchers found that with supplementation of the nutrients, men and women 65 and older lost significantly less body bone and, in some cases, gained bone mineral density. n Two studies published in American Heart Association journals show that atherosclerosis and osteoporosis may be linked by a common problem in the way the body uses calcium. The September 1997 Stroke revealed that, in a group of 30 postmenopausal women 67 to 85 years old, bone mineral density declined as atherosclerotic plaque increased. Researchers reporting in Circulation (September 15, 1997) advanced the theory that the osteoporosis-atherosclerosis connection may be related to a problem in handling calcium. n For people who had colon polyps removed, taking calcium supplements decreased the number of new polyps by 24% and cut the risk of recurrence by 19%, according to researchers at the University of North Carolina, Chapel Hill, School of Medicine. The study, published in the January 14, 1999 New England Journal of Medicine, was a first in crediting calcium with anti-cancer properties.

The D Factor

Without adequate vitamin D, your absorption of calcium slips and bone loss can accelerate, increasing the risk for fractures. Fifty percent of women with osteoporosis hospitalized for hip fractures at Brigham and Women's Hospital in Boston had a previously undetected vitamin D deficiency (Journal of the American Medical Association, April 28, 1999). University of Pittsburgh Cancer Institute researchers told participants at the April 14, 1997 meeting of the American Association for Cancer Research that vitamin D "significantly inhibits highly metastatic, or widespread, prostate cancer in animals," suggesting its potential for treating men with similar conditions. Few foods that Americans eat, except dairy, contain much vitamin D, but we can usually synthesize sufficient amounts from as few as five minutes' exposure to the sun. But as skin ages, its ability to act as a vitamin D factory decreases. According to Michael F. Holick, the director of the Vitamin D, Skin and Bone Research Laboratory at Boston University Medical Center, upwards of 40% of the adult population over age 50 that he sees in his clinic are deficient in vitamin D. Recently, the National Academy of Sciences (the official body that decrees the required amounts of necessary nutrients) increased the daily recommendations of vitamin D to 600 IU for people over 71, 400 IU for those aged 51 to 70 and 200 IU for people under 50. The best dietary sources, apart from dependable supplements, are dairy and fatty fish like salmon. Four ounces of salmon provide about 300 IU.

The Facts About Fats

The American lust for low-fat, high-carbohydrate diets filled with sugary foods has exploded into nothing short of "obsession," according to experts at the General Research Center at Stanford University Medical Center (Am J Clin Nutr 70, 1999: 512S-5S). That mania oftens robs us of the crucial balance of omega-3 and omega-6 fatty acids typical of the Mediterranean diet that protect us from heart disease by controlling cholesterol and making blood less likely to form clots. These fatty acids cannot be made by the body but are critical for health: n Omega-3 fatty acid (linolenic acid) comes from fresh, deepwater fish (salmon, mackerel, sardines) and vegetable oils such as canola, flaxseed and walnut. n Omega-6 fatty acid (linoleic acid) found primarily in raw nuts, seeds and legumes and in saturated vegetable oils such as borage, grape seed, primrose, sesame and soybean. The American Heart Association recommends limiting total fat consumption to 30% of daily calories. Saturated fats like those in dairy and meat products as well as vegetable oil should comprise 10% of total calories; total unsaturated fat (fish oils, soybean, safflower nuts and nut oils) should be restricted to 20 to 22% of daily calories.

Be Sure About B12

Vitamin B12 presents a particular problem for the elderly because older digestive systems often don't secrete enough stomach acid to liberate this nutrient from food. (The elderly have no problem absorbing B12 from supplements, because it's not bound to food.) Vitamins generally moderate the aging process but, ironically, that process and the diseases that frequently accompany it affect vitamin metabolism (Schweiz Rundsch Med Prax 83, 1994: 262-6). And because of those changes, we need more of certain vitamins. This is the case for vitamins D, B6, riboflavin and B12. Crucial for health, B12 is necessary to prevent anemia, and, according to recent studies, needed (along with folate and B6) to help stave off heart disease. B12, with thiamine and niacin, boosts cognition (Adv Nutr Res 7, 1985: 71-100). Screening for vitamin B12 deficiency and thyroid disease is cheap and easy and can prevent conditions such as dementia, depression or irreversible tissue damage (Lakartidningen 94, 1997: 4329-32). In the January 5-12, 1999 issue of Circulation: Journal of the American Heart Association, the AHA urged doctors to screen levels of homocysteine (the amino acid byproduct of protein digestion that damages arteries, causes heart disease and, possibly, strokes) in patients at high risk for heart disease. They also recommended all Americans to up their daily levels of vitamins B6 and B12, as well as folic acid. Since fruits, vegetables or grains lack B12, vegetarians need B12 supplements. And they're a good idea for the rest of us, too.

Folic Acid Benefits

Folic acid made headlines in the early 1990s when the U.S. Public Health Service declared that "to reduce the frequency of neural tube defects [spina bifida, or open spine, and anencephaly, a lethal defect of the brain and skull] and their resulting disability, all women of childbearing age in the United States who are capable of becoming pregnant should consume .4 milligrams (400 micrograms) of folic acid per day." This recommendation followed voluminous research that showed taking folic acid was associated with a significantly reduced risk of birth defects. (The advisory is based on the fact that nearly half of all pregnancies are unplanned. If you think you are pregnant, consult your health practitioner for supplementary advice.)

A Team Player

Folic acid's efficacy intensifies when it works with other nutrients. Among many studies on the preventive powers of folic acid on birth defects, one published in The New England Journal of Medicine (327, Dec. 24, 1992: 1,832-1,835), disclosed an even greater decrease in neural tube defects when supplements of folic acid contained copper, manganese, zinc and vitamin C. As a warrior against homocysteine, folic acid joins the battalion of B12 and B6 in detoxifying this harmful protein. At the University of Washington's Northwest Prevention Effectiveness Center, researchers recently analyzed 38 published studies of the relationship between folic acid, homocysteine and cardiovascular disease and, according to associate professor Shirley A. Beresford, MD, folic acid and vitamin B12 and B6 deficiencies can lead to a buildup of homocysteine.

Compelling Evidence

Canadian researchers reported in the Journal of the American Medical Association (275, 1996: 1893-1896) that men and women with low folic acid have a 69% increase in the risk of fatal coronary heart disease. This 15-year study of more than 5,000 people stressed the need for dietary supplementation of folic acid. Folic acid also has been credited with the potential to protect against cancers of the lungs, colon and cervix. It appears to help reverse cervical dysplasia, the precursor cells to cervical cancer, especially for women taking oral contraceptives, which may cause a localized deficiency of folic acid in the cells of the cervix. According to Shari Lieberman, PhD, and Nancy Bruning, authors of The Real Vitamin & Mineral Book (Avery), folic acid derivatives work with neurotransmitters, the chemicals that permit signals to be sent from nerve fiber to nerve fiber. A lack of folic acid can cause some nervous-system disorders, such as depression, schizophrenia and dementia; it also may be related to some forms of mental retardation. Other supporting roles of folic acid, according to researchers: the formation of normal red blood cells, important for preventing the type of anemia characterized by oversized red blood cells; strengthening and improving white blood cell action against disease; limiting production of uric acid, the cause of gout.

The Best Sources

Many foods are rich in folic acid: beef, lamb, pork and chicken liver, spinach, kale and beet greens, asparagus, broccoli, whole wheat and brewer's yeast. But experts believe that only 25 to 50% of the folic acid in food is bioavailable. Processing also reduces an estimated 50 to 90% of its content. Folic acid supplementation overcomes these obstacles with little risk, as it has no known toxicity. Women taking folic acid who are current or former users of oral contraceptives may require additional zinc. And be sure to augment your folic acid supplement with its synergistic counterpart, vitamin B12.

Focus on Fiber

The American Heart Association came out squarely behind fiber in a June 16, 1997 issue of its journal Circulation: Double your daily intake to lower cholesterol and the risk of heart disease. The American diet is consistently low in fiber, notes Linda Van Horn, PhD, RD, author of the article. Twenty-five to 30 grams a day from foods (or supplements) are not only heart healthy but seem to aid weight control.

Iron Problem

Getting enough iron? An estimated 25% of adolescent girls in the United States are iron deficient, according to an October 12, 1996 issue of the British medical journal The Lancet, which reported that girls who took iron supplements performed significantly better on verbal tests than those who took a placebo. "Teenage girls should be regularly tested for iron deficiency because rapid growth and the onset of menstruation during puberty increase the body's need for iron," says Ann Bruner, MD, of the Johns Hopkins Children's Center and a lead author of the study.USDA data reveal that women up to age 50 also tend to get much less than recommended levels of iron, a lack of which leads to anemia, a deficiency of red blood cells, hemoglobin or volume of blood. For kids, deficiency is more common from six months to four years and during the rapid growth spurts of adolescence when the body is growing so quickly that the body's iron stores may sink to dangerous levels. Vegetarian women run the greatest risk for deficiency, as meat is iron-rich; foods like beans, grains and vegetables also contain some iron. Supplements, of course, supply easily absorbable iron. And to absorb iron from vegetarian sources, take vitamin C with your meals. That boosts the amount of this mineral you will take in. Bear in mind, however, that certain folks-older men and post-menopausal women-generally have adequate dietary supplies of iron. Of greater concern, in fact, is excessive iron, and for these folks iron-free multivitamin and mineral supplements are available.

Ante Up the Antioxidants

Antioxidant nutrients help protect the body from oxygen-scavenging molecules called free radicals. The products of pollution, the body's own metabolic processes and other sources, free radicals are linked to heart disease, cancer and other chronic health problems. The most important antioxidants, which include vitamin C, E, beta carotene, and selenium, are often lacking in the American diet. Plus, optimal amounts of vitamin E cannot be consumed from food. You need supplements. The bottom line: even though we live in a land of plenty, you can still miss vital nutrients. So make sure to consume these vital substances.

Sprouts: Nutritional

Source of Missing Nutrients In the search for the nutrients missing from America's diet, one big help is the sprout. The sprout is truly one of nature's heavyweights: fresh, tiny and moist, its power punch of vitamins, minerals, protein, chlorophyll and disease-busting phytochemicals land it in a weight class far beyond that of its full-grown competitors. Size does NOT matter to this nutritional giant. A championship belt currently wraps around the miniscule broccoli sprout, catapulted into the ring by Paul Talalay, MD, professor of pharmacology and molecular sciences at Johns Hopkins University. Dr. Talalay discovered that the seedlings contain substantially more of the cancer-fighting substance sulforaphane than mature plants (Proc. Natnl. Acad. Sci. USA, 94, 10367-10372). Sprouts, the quintessential health food of the Sixties, provide a wonderfully varied and versatile way to get your daily greens. Raw or cooked, strong or mild, vegetable and grass sprouts and their algae cousins add low-calorie texture to recipes and a rich, diverse complement of nutrients and fiber.

Ancient Asia to the Modern Lab

Asians stir-fried sprouts as one of the earliest fast foods as long as 5,000 years ago. The ancient Chinese relied on sprouts for year-round vegetables in colder regions of their vast country. Today, researchers studying sprouts and adult plants have identified their important chemoprotective and other health-bolstering substances. In Paul Talalay's research project at Johns Hopkins, scientists found that three-day-old broccoli sprouts contain up to 50 times more sulforaphane than mature plants, which prompts the body to produce an enzyme that prevents cancer tumors from forming. Uniform levels of the compound saturate the shoots, unlike the chemically uneven adult plants. The Brassica family of broccoli and cabbage is richly endowed with phytochemicals that also help reduce estrogen levels associated with breast cancer. Other phytochemical compounds in the Brassica family are associated with the prevention of stomach and lung cancers. Most of the initial landmark work on phytochemicals' cancer-fighting powers has taken place since 1989 under the aegis of the National Cancer Institute's "Designer Food Program," which isolated, for example, the isoflavones in beans that seem to neutralize cancer-gene enzymes.

Strong Suit: Soy and Spirulina

The isoflavones and phytosterols in soy produce an estrogenic effect that appears to relieve menopausal symptoms and help prevent breast cancer. Soy foods expert Mark Messina, PhD, has done extensive work on the subject, some of which has been published in the Journal of the National Cancer Institute 83, 1991: 541-6. Researchers also have synthesized a bone-strengthening form of soy isoflavones called ipriflavone, following impressive clinical trials in the treatment of osteoporosis (American Journal of Medicine, 95 [Suppl. 5A] (1993): 69S-74S). Spirulina and other micro-algae are fascinating organisms that inhabit a niche between the plant and animals kingdoms. Named for its tiny spirals, spirulina, a blue-green algae, grows in saline lakes but is cultured for maximum nutritional content. In her book Whole Foods Companion (Chelsea Green), Dianne Onstad notes that spirulina contains "the highest sources of protein, beta carotene and nucleic acids of any animal or plant food." Its nucleic acids, she says, benefit cellular regeneration; its fatty acids, especially GLA and omega-3 acids, make it one of the most complete foods. Sprouts, like any other produce, should be rinsed thoroughly before serving. People at high risk for bacterial illness-young children, the very elderly or folks with weakened immune systems-should limit their consumption of raw sprouts. But no matter how you eat them, you may find more spring in your step from these tiny, sprouting nutritional wonders.

Subject: Nutritional Scorecard

Nutritional Scorecard by Sylvia Whitefeather Energy Times, June 15, 2004

For over 50 years, the federal government has produced Recommended Daily Allowances (RDAs) as guidelines for vitamin and mineral intake. Then, in 1993, the Reference Daily Intakes (RDIs) superseded the RDAs. By applying this new designation, the government's guidelines are now supposed to represent the designated amounts that an average person should consume. With this in mind, and the fact that many experts think you should consume more than some of the RDIs, how does your nutritional scorecard add up? Answering a few nutritional questions can point you in the right direction.

Perfect Protein

Are you trying to lose weight? If you are, the latest thinking on weight loss opines that eating more protein may be the key to keeping your weight down. Two recent studies published in the Annals of Internal Medicine (5/18/04) found that people who ate a low-carbohydrate, high-protein diet lost more weight and had better cholesterol levels than dieters who ate fewer fatty foods. Both studies found that a low-carb diet can improve your triglycerides (blood fats) and boost your HDL, or good, cholesterol.

Eating protein satisfies both tummies and taste buds. Researchers have found that the amount of protein eaten in a meal determines not only how much food you eat but also how satisfied you feel after eating (J Nutr 2004 Apr; 134(4):974S-9S). And when you feel satisfied after eating less food you improve your odds of losing weight.

We need about 50 grams of protein a day to support the body's functions. The best sources of protein are eggs, meat, milk, protein shakes and yogurt.

Classy Carbohydrates

Does your energy level go up and down during the day? To get off the energy rollercoaster, cut down on carbohydrates, and make sure the carbs you do eat are complex.

Carbohydrates have been getting some unflattering press lately. Yes, if you want to lose weight, you may want to go on a strictly low-carb diet. But for those not concerned with weight, carbohydrates are the principle source of energy for the body.

What's more, even if you do restrict carbohydrates, you should still eat a tiny bit of them. Without some carbs in the diet your body cannot regulate protein or fat metabolism. According to Michael and Mary Eades, MD, authors of The 30-Day Low-Carb Diet Solution (Wiley), "Carbohydrates control insulin and insulin controls your metabolic health."

So, make your carbohydrates count. Indulge in complex carbohydrates: whole grains, fruits and vegetables. In those foods, carbs are accompanied by fiber and larger amounts of vitamins and phytonutrients. Other reliable sources of complex carbohydrates are whole wheat bread, brown rice and oatmeal.

Fabulous Fiber

Are you concerned about your heart health? Fiber from beans, oats, legumes, nuts, rice bran, fruits and vegetables helps stabilize blood sugar and reduce cholesterol. Pectins, found in apples, pears, prunes and plums, are a particularly useful form of water-soluble fiber.

Insoluble fiber, in cereals, wheat bran and vegetables, reduces the risk of colon-related problems. In addition to adding fiber to the diet, dried beans and soybeans have been shown to lower cholesterol, improve vascular health and kidney functioning, preserve bone mineral density and reduce menopausal discomforts (AJCN 1999 Sept; 70(3 suppl):464S-74S). Fiber also promotes good bowel health and encourages the growth of beneficial intestinal flora.

You need 25 to 40 grams of fiber daily. If you have cut back on your carbohydrates, be sure to take a reliable fiber supplement.

Fantastic Fats

Do you have problems focusing on mentally challenging tasks? If so, you should eat more fish and get more of the omega-3 fatty acids that fish and flax contain. Higher levels of this type of fat have been linked to better concentration while performing demanding intellectual work (Lipids 2004 Feb; 39(2):117-23).

Fats add flavor to food, making meals taste better. Monounsaturated fats like plain olive oil and canola are liquid at room temperature and are suitable for use in cooking at high temperatures. Researchers have found that a diet high in monounsaturated fat has the ability to decrease LDL (bad) cholesterol (J Nutr 2001; 131:1758-63). Other fats, such as extra virgin olive oil and flaxseed oil, are best used in dishes that don't need cooking, such as salads.

Although the RDI for fat is less than 30% of the total calorie intake, some researchers believe that if you eat healthy fat, eating too much is not a concern. Omega-3 fats are available in supplement form.

Wonderful Water

Do you suffer from dry skin? You may not be drinking enough water. This precious liquid is used by every cell of our bodies and makes up 60% to 75% of our body weight. Water is important for kidney function. Researchers in Italy found that drinking adequate amounts of water can help prevent the formation of kidney stones (Urol Int 2004; 72 Suppl 1:29-33).

Your activity level, environment and diet influence how much water you need daily. Try to drink at least eight cups of fluid a day from noncaffeinated, nonalcoholic sources.

Voluptuous Vitamins

Do you exercise frequently? If you do, you need more antioxidant vitamins like natural vitamin E and vitamin C as well as a healthy supply of carotenoids. A study at the School of Applied Medical Sciences and Sports Studies, University of Ulster, found that exercisers need more antioxidants. Otherwise, their exertion may release an excess number of free radicals (caustic molecules) in their bodies and do damage to the heart arteries and other internal organs.

Vitamins, in general, are defined as micronutrients that are necessary for life. They are necessary for the production of energy, a healthy immune system and hundreds of other functions in the body.

Vitamins aren't the only substances that produce big benefits in small quantities. Phytonutrients are chemicals in plants that have health-promoting properties. These nutrients are getting more and more attention from researchers who are keeping score on our nutritional requirements.

Mineral Crunch

Do your meals contain plenty of calcium? If not, you may need supplements to keep your bones strong and help keep your weight down. One study, presented at the Experimental Biology 2003 meeting in San Diego, found that young women who consumed more calcium had better luck controlling their weight. In this research, it didn't take much calcium to make a difference in waistlines. Consuming just one more serving daily (a cup of milk or a thumb-sized piece of cheese, each of which contain about 300 mg of calcium) made, on average, about a two-pound difference.

In addition, many experts recommend multimineral supplements (along with multivitamins) to promote better health. A recent study of people with immune problems, for instance, found that those kinds of supplements seem to help boost the immune system (AT News 2004 Feb 27; 398:4-5).

Subject: Celebrating Women: Age Is Just a Number

Celebrating Women: Age Is Just a Number by Carl Lowe Energy Times, March 10, 2004

As women age, their physical needs shift. The health challenges that face a woman in her thirties do not match those of a woman in her fifties.

At the same time, some basic health needs stay constant: At any age, every woman requires a wealth of vitamins, minerals and the other natural chemicals that fruits, vegetables and supplements supply. She also constantly needs families and friends to support her spiritual health.

As the internal workings of your body alter, your lifestyle must stay abreast of those adjustments. Peak health demands a finely tuned health program designed with your individual needs-and your stage of life-in mind.

Ages 30 to 45

When it comes to maintaining health, younger women might seem to have it easier than older women. If they exercise and stay in shape, they maintain more stamina than women 10 to 20 years their senior.

Unfortunately, many women in this age group mistakenly think they don't have to be as careful about their lifestyle habits and their eating habits as they will in later decades. But even if your health doesn't seem to suffer from poor eating choices or a sedentary lifestyle right away, your foundation for health in later life suffers if you don't care for yourself now.

By age 45 you should have established the good habits that will carry you successfully through the aging process. As an added bonus, good lifestyle habits pay immediate dividends. If you pay attention to your nutrients and get plenty of physical activity when younger, you'll feel more energetic and probably enjoy better emotional health.

Set Health Goals

According to Gayle Reichler, MS, RD, CDN, in her book Active Wellness (Avery/Penguin), good health at any age doesn't just come to you-you have to plan for it. In order to stick to good habits, she says, "living a healthy lifestyle needs to be satisfying." Reichler believes that you need to picture your health goals to achieve them: "Every successful endeavor first begins in the mind as an idea, a thought, a dream, a conviction." Good health at this age and in later years requires a concrete strategy and visualization of how your body can improve with a healthy lifestyle.

Your long-term health goals at this age should include an exercise program that will allow you to reach a physically fit old age with a lowered risk of disability. In addition, your short-term plans should encompass losing weight, staying optimistic, living life with more vim and vigor, increasing your capacity for exercise and lowering your stress.

As Reichler points out, "Your long-term goal and your ideal vision establish what you want to achieve....[You should do] something good...for yourself every day and every week that makes your life easier and more consistent with your goals."

Develop an Eating Plan

Today, the average American gains about two pounds annually. As a result, every year a greater portion of the US population is obese and overweight. By controlling your food intake earlier in life, you may be able to avoid this weight gain. In his book Prolonging Health (Hampton Roads), James Williams, OMD, recommends basic changes to your diet that can provide long-term support of your health:

Get Supplemental Help

If you're in your thirties or forties and you don't take at least a multivitamin, start taking one today! A large body of research shows that taking vitamin and mineral supplements over a long period of time significantly supports better health.

Calcium and vitamin D are two of the most important supplemental nutrients, helping to build stronger bones now that can withstand the bone-loss effects of aging.

Calcium can also help keep your weight down. One study of younger women found that for every extra 300 milligrams of calcium a day they consumed, they weighed about two pounds less (Experimental Biology 2003 meeting, San Diego).

In the same way, taking vitamin D supplements not only helps strengthen your bones, it can also lower your risk of multiple sclerosis (Neurology 1/13/04). In this study, which looked at the health records of more than 180,000 women for up to 20 years, taking D supplements dropped the chances of multiple sclerosis (although eating vitamin D-rich foods did not have the same benefit). And if you're thinking about having children at this age, a multivitamin is crucial for lowering your baby's risk of birth defects and other health problems. A study at the University of North Carolina at Chapel Hill found that women who take multivitamins during pregnancy lower their children's risk of nervous system cancer by up to 40% (Epidemiology 9/02).

" Our finding, combined with previous work on reducing several birth defects with vitamin supplementation and other childhood cancers, supports the recommendation that mothers' vitamin use before and during pregnancy may benefit their babies' health," says Andrew F. Olshan, MD, professor of epidemiology at the UNC School of Public Health. "We believe physicians and other health care providers should continue to educate women about these benefits and recommend appropriate dietary habits and daily dietary supplements."

In particular, Dr. Olshan feels that folic acid (one of the B vitamins), and vitamins C and A, are particularly important for lowering the risk of childhood cancers and birth defects.

Ages 45 to 55

When you reach this in-between age-the time when most women have moved past childbearing age but haven't usually fully moved into the post-menopausal stage-you enjoy a propitious opportunity to take stock of your health and plan for an even healthier future. One thing that may need adjustment is your sleep habits, as sleeplessness is a common problem for women in this age group. Even if you haven't been exercising or watching your diet until now, it's not too late to start. Making lifestyle changes at this age can still improve your chances for aging successfully.

For instance, it is at these ages that women should have their heart health checked. Research published in the journal Stroke (5/01) shows that having your cholesterol and blood pressure checked at this time more accurately shows your future chances of heart disease than having it checked at a later date after menopause, in your late fifties.

" The premenopausal risk factors may be a stronger predictor of carotid atherosclerosis [artery blockages] because they represent cumulative risk factor exposure during the premenopausal years, whereas the risk factors...during the early postmenopausal years have a shorter time for influence," says Karen A. Matthews, PhD, a professor at the University of Pittsburgh Medical Center. In other words, Dr. Matthews' research shows that if you have high blood pressure and high cholesterol before menopause, you are at serious risk for a stroke or heart attack soon after menopause: These are important reasons that you need to start improving your health habits immediately.

Increase in Heart Disease

Before menopause, a woman's hormones and other physiological characteristics usually hold down her chance of heart disease. After menopause, when hormones and other bodily changes occur, the risk of heart attacks and stroke in women rises significantly. (Heart disease is the leading killer of women.) At least part of this increased risk is linked to the postmenopausal decrease in estrogen production.

Dr. Matthews studied about 370 women in their late forties, measuring their weight, their BMI (body mass index, an indication of body fat compared to height), blood pressure, cholesterol and blood sugar. Ten years later, after the women had entered menopause, she and her fellow scientists used ultrasound to measure blockages in these women's neck arteries (a sign of heart disease).

The researchers found that indications of potential heart problems (such as high blood pressure, high cholesterol and being overweight) when women were in their forties did indeed forecast future difficulties.

" Women who had elevated cholesterol, higher blood pressures and increased body weight before menopause had increased blood vessel thickening and atherosclerotic plaque formation in the neck arteries after menopause. Such changes in the carotid arteries are associated with an increased heart attack and stroke risk," says Dr. Matthews.

Heart Health Factors

The four main lifestyle factors you should adjust at this age to support better heart function are diet, stress, exercise and weight. According to Dr. James Williams, "[M]ore than any other cause, dietary factors are the most critical factor in cardiovascular disease." He recommends eliminating "dietary saturated fatty acids as found in flame-broiled and fried meats." He also urges women to eat more fish and poultry, consume organic fruits and vegetables and cut back on refined sugar.

Stress becomes an ever more important heart disease factor at this age as estrogen begins to drop.

" Our study [in the lab] indicates that stress affects estrogen levels and can lead to the development of heart disease-even before menopause," says Jay Kaplan, PhD, of the Wake Forest University Baptist Medical Center (The Green Journal 3/02).

Dr. Kaplan's research shows that stress in women ages 45 to 55 may reduce estrogen earlier in life and make women more susceptible to the arterial blockages that lead to heart disease. "We know from [lab] studies that stress can lower estrogen levels to the point that health is affected," he says.

Stress can also hurt bone health: In a study of 66 women with normal-length menstrual periods, estrogen levels were low enough in half of the women to cause bone loss, making the women susceptible to osteoporosis.

Exercise and Weight

Although exercise used to be considered to be mainly a young woman's activity, the thrust of recent research suggests that physical activity actually becomes more important to health as you get older.

A 17-year study of about 10,000 Americans found that exercising and keeping your weight down is probably the most important thing you can do to lower your risk of heart disease as you enter your forties and fifties (Am J Prev Med 11/03).

Of the people who took part in this study, more than 1,500 people died of heart disease. Those who performed the most exercise were thinner and had a 50% chance less of dying of heart disease than overweight nonexercisers.

" The fact is that those who both exercised more and ate more nevertheless had low cardiovascular mortality," says Jing Fang, MD, a researcher at the Albert Einstein College of Medicine in the Bronx, New York.

An added benefit of exercise: If you burn up calories exercising, you can eat more and not have to worry as much about being overweight.

Supplements and Diet

If you're a woman at midlife, a multivitamin and mineral is still good nutritional insurance. Eating plenty of fruits and vegetables are also important for getting enough phytochemicals, the health substances in plants that convey a wealth of health benefits.

As you enter this age group, your immune system gradually slows down. To help support immune function, eating produce rich in antioxidant nutrients, and supplementing with antioxidants like vitamins C and E as well as carotenoids, can be especially important. For example, a study of people with ulcers found that people with less vitamin C in their stomachs are more likely to be infected with Helicobacter pylori, the bacteria that can cause peptic ulcers and is linked to stomach cancer (J Amer Coll Nutr 8/1/03).

This research, which looked at the health of about 7,000 people, found that vitamin C probably helps the immune system fend off this bacterial infection.

" Current public health recommendations for Americans are to eat five or more servings of fresh fruits and vegetables a day to help prevent heart disease, cancer and other chronic diseases," says Joel A. Simon, MD, MPH, professor of medicine at the University of California at San Francisco.

Calcium and Bones

At midlife, calcium continues to be a vital mineral for supporting bone health.

According to Gameil T. Fouad, PhD, "It has been routinely shown that a woman's calcium status and level of physical activity (specifically, the degree to which she participates in weight-bearing exercise) are positively associated with bone mineral density. It is less well appreciated that this is a process which takes place over the course of a lifetime."

Dr. Fouad adds that calcium works in concert with other vitamins and minerals to keep bones healthy: "Research in the United Kingdom involving nearly 1,000 premenopausal women over age 40 illustrates those women with the highest bone density tended to have the highest intake of calcium. Surprisingly, this study also demonstrated that calcium does not act alone: those women with the best bone health also had the highest intakes of zinc, magnesium and potassium."

Dr. Fouad stresses that supplements should go together with a lifestyle that includes enough sleep and exercise to help the body stay in top shape.

" As a general guideline," he says, "a woman concerned with her mineral intake should take concrete steps to make sure she is getting adequate rest, is eating a well-balanced diet focused on fresh fruits, vegetables and lean protein as well as getting adequate exercise....A multi-mineral containing bio-available forms of zinc, magnesium, copper and selenium is probably a safe addition to anyone's routine. Taking these proactive steps dramatically reduces the chances that deficiencies will arise."

Ages 55 and Beyond

Entering the post-menopausal phase of life can present challenging opportunities for a new perspective on life and health. While some signs of aging are inevitable, experts who have looked at how the human body changes with age are now convinced that healthy lifestyle habits can improve how well you can think, move and enjoy life well past age 55.

As Dr. Williams notes, "In your fifties, the force of aging is undeniably present: Your body shape changes and organ function declines, both men and women have a tendency to gain weight....Heart disease becomes more common, energy and endurance are considerably reduced and your memory begins to slip."

But Dr. Williams also points out that you don't have to age as rapidly as other people do. He believes you should employ a "natural longevity program...[that starts] to reverse the course of aging as early as possible."

One key to staying vital as you age is your outlook on life, an aspect of life that's greatly enhanced by strong social ties.

Avoiding the Aging Slowdown The latest research shows that one of the most crucial ways to slow the effects of aging is to exercise and keep your weight down. It won't necessarily be easy, though. The change in hormonal balance at this age makes the body more prone to extra pounds (Society for Neuroscience Meeting, 11/12/03).

" In women, it has been demonstrated that major weight increases often occur during menopause, the time in a woman's life in which cyclic ovarian function ends and the ovarian hormones estrogen and progesterone decline," says Judy Cameron, PhD, a scientist in the divisions of reproductive sciences and neuroscience at the Oregon Health & Science University.

In Dr. Cameron's lab trials, she has found that the decrease in estrogen after menopause "resulted in a 67% jump in food intake and a 5% jump in weight in a matter of weeks."

In other words, the hormonal changes you undergo as enter your late fifties causes your appetite to grow as well as your waistline: Developments that increase your chances of heart disease, cancer, diabetes, stroke and joint problems.

Vigilance against this weight gain is necessary to save your health: Start walking and exercising. Research on exercise in people aged 58 to 78 found that getting off the couch for a walk or other physical activity not only helps control weight but also helps sharpen your thinking and helps you become more decisive (Proceedings of the National Academy of Sciences, 2/16-20/04, online edition). This recent study, done at the University of Illinois at Urbana-Champaign, found that performing aerobic exercise improved mental functioning by 11% (on a computer test).

" We continue to find a number of cognitive benefits in the aerobic group," says Arthur F. Kramer, PhD, a professor of psychology at the Beckman Institute for Advanced Science and Technology at Illinois. "The brain circuits that underlie our ability to think-in this case to attend selectively to information in the environment-can change in a way that is conducive to better performance on tasks as a result of fitness." In simple terms, that means that walking at least 45 minutes a day boosts brain power as well as protecting your heart.

An Herb for Menopause

The physical changes that accompan> y menopause can be uncomfortable. But traditional herbal help is available: Black cohosh (Cimicifuga racemosa), an herb used for eons by aging women, has been shown in recent studies to be both safe and effective (Menopause 6/15/03).

" This [research] should reassure health professionals that they can safely recommend black cohosh to their menopausal patients who cannot or choose not to take HRT [hormone replacement therapy]," says researcher Tieraona Low Dog, MD, Clinical Assistant Professor at the University of New Mexico Department of Family and Community Medicine.

While HRT has been used to help women cope with menopause, a flurry of studies in the past few years have shown that HRT increases the risk of heart disease and cancer. Instead, black cohosh, which alleviates such menopausal discomforts as hot flashes, has been shown to be much safer.

Keeping Track of Crucial Vitamins

While continuing to take multivitamins and minerals at this age is important, some experts believe that as we grow older, vitamin D supplementation, as well as taking antioxidant nutrients, is particularly vital. Arthritis is a common affliction of aging, and rheumatoid arthritis (RA) is one particularly destructive form of this joint problem. But taking vitamin D can significantly lower your risk of this condition.

When scientists analyzed the diets of 30,000 middle-aged women in Iowa over 11 years, they found that women who consumed vitamin D supplements were 34% less likely to suffer RA (Arth Rheu 1/03).

Other vitamins are equally important to an older woman's well-being. For example, vitamins C and natural E have been found to lower the risk of stroke in those over the age of 55 (Neurology 11/11/03). In this study, smokers who consumed the most vitamin C and natural vitamin E were 70% were much less likely to suffer strokes than smokers whose diets were missing out on these vitamins.

Rich sources of vitamin C in food include oranges and other citrus fruits, strawberries, red and green peppers, broccoli and brussels sprouts. Sources of vitamin E include vegetable oils such as sunflower seed, cottonseed, safflower, palm and wheat germ oils, margarine and nuts.

Saving Your Sight

After age 55, your eyes are particularly vulnerable. Eight million Americans of this age are at risk for age-related macular degeneration (AMD), a condition that destroys structures in the back of the eye necessary for vision (Arch Ophthal 11/03). But you can drop your risk of AMD by taking supplements of antioxidant vitamins and zinc, according to researchers at Johns Hopkins' Wilmer Eye Institute.

Their research shows that a dietary supplement of vitamins C, natural vitamin E and beta carotene, along with zinc, lowers the chances of progressing to advanced AMD in certain at-risk people by about 25%. Daily supplements also reduced the risk of vision loss by about 19%.

The carotenoids lutein and zeaxanthin also help protect aging eyes. When scientists compared healthy eyes with eyes suffering from AMD, they found that AMD eyes contained lower levels of these vital nutrients (Ophthalmology 2003; 109:1780). Furthermore, they found that levels of these chemicals generally decline as you grow older.

Healthy at All Ages

When it comes to designing a healthy lifestyle, general rules like these can be followed, but you should individualize your plan to fit your needs. No matter which type of exercises you pick out or what healthy foods you choose, look for a strategy and a plan you can stick to. If you think a selection of foods are good for you but you absolutely hate their taste, chances are you won't be able to stick to a diet that includes them.

The same goes for exercise: Pick out activities that you enjoy and that you can perform consistently. That increases your chance of sticking to an exercise program.

Staying healthy is enjoyable and it helps you get more out of life every day, no matter what stage of life you're in.

Bone Power by no author Energy Times, May 1, 1997

Patricia Q. stopped smoking 20 years ago. At 61, she is active, tries to exercise regularly, eats properly and takes a multivitamin. Most would consider Patricia's lifestyle a sufficient safeguard against the diseases of aging. But one debilitating possibility still concerns her: Osteoporosis-bone thinning. She worries that her bones may have begun weakening almost a decade ago. Although her good health habits can slow the demineralization of her bones, osteoporosis may still take its toll. And as her neck and back begin to obviously round, a possible sign of bone weakness, Patricia frets about her future.

The weakening of bones brought on by age makes them more prone to fracture. One of every two women older than age 50 suffers an osteoporosis-related fracture during her lifetime. Osteoporosis literally means "porous bones," bones that deteriorate and particularly increase the risk of damage to the hip, spine and wrist. In extreme cases, everyday activities assume danger: fractures can result from simply lifting a bag of groceries or from what would otherwise be a minor fall. Some women, fearful of fractures, eliminate many seemingly innocuous activities from their daily lives. Their fear is well founded. Complications from these fractures are a major killer of women.

As women grow older, the risk grows, too. Ten million individuals already have the disease, and 18 million have low bone mass, placing them at risk for osteoporosis.

But research shows that osteoporosis may be preventable and controllable. Regardless of age, eating right, getting enough calcium and performing weight-bearing exercises, can lower your risk for this disease.

Understanding Your Bones

Bones are not static structures but living tissue constantly reformed in a process called remodeling. Every day old bone is removed and replaced with new bone tissue. When more bone is broken down than is replaced (demineralization), bones weaken. When the structure loses sufficient density, you face eminent danger of a fracture.

Generally speaking, bones continue to increase their density and calcium content until you reach your 30s, at which point you probably have attained your peak bone mass. Afterward you may either maintain this mass or begin to lose calcium yearly, but you rarely can increase bone density. The loss of bone density can increase at menopause, when your body ceases producing estrogen, a hormone required to improve bone strength. In addition, some medications, used for a long period, compromise bone density.

Stop Calcium Loss

Eating a diet rich in nutrients that help your bones stay strong should be the first step in stopping or slowing the process of osteoporosis. Calcium, magnesium, vitamin D, phosphorus, soy-based foods and fluoride compose the major nutrients that strengthen bone.

At this moment, 98 percent of your body's calcium resides in your bones, the rest circulates in the blood, taking part in metabolic functions. Because the body cannot manufacture calcium, you must eat calcium in your daily diet to replace the amounts that are constantly lost. When the diet lacks sufficient calcium to replace the amount that is excreted, the body begins to break down bone for the calcium necessary for life-preserving metabolic processes.

Calcium in the diet can generally slow calcium loss from bones, but it usually doesn't seem to replace calcium already gone. The National Institutes of Health recommend 1000-1200 milligrams of dietary calcium per day for premenopausal women and 1200-1500 milligrams for menopausal and postmenopausal women

Good sources of calcium include milk and milk products, yogurt, ricotta, cheese, oysters, salmon, collard greens, spinach, ice cream, cottage cheese, kale, broccoli and oranges.

If you cannot tolerate dairy products, calcium supplements are an easy way to consume calcium. Take supplements with a meal to aid absorption of calcium from the stomach.

In Total Health for Women, Dr. Kendra Kale, clinical assistant professor of medicine at the University of Pennsylvania School of Medicine, urges women to read supplement labels. Scrutinize the fine print to see how many grams are considered "elemental"or "bioavailable"-the form of calcium your body will absorb. If you're taking a 750 milligram supplement, chances are only 300 milligrams are elemental. You should also check that the pill will dissolve within 30 minutes and meets the United States Pharmacopoeia (USP) standards. If tablets do not break down within 30 minutes, they may pass through you unabsorbed and you won't digest the calcium from them that you need.

Absorbing calcium from your digestive tract also requires the presence of vitamin D. Ten to 15 minutes of sun exposure daily usually satisfies vitamin D requirements since most people's bodies can use sunlight to manufacture this substance. So walking to work, or going outside for lunch should supply sufficient ultraviolet light to facilitate calcium absorption.

As we age, however, our body's ability to produce vitamin D gradually diminishes. Our diets can make up the difference: Good dietary sources of vitamin D include egg yolks, liver and fish or nutritional supplements. Many foods, like milk, are supplemented with vitamin D.

Magnesium is another mineral that helps to build bones. Found in leafy, green vegetables, nuts, soybeans, seeds and whole grains, your daily requirement of magnesium should be about half of your calcium intake.

Absorbing calcium for bone health also requires phosphorus, but be careful not to get too much of a good thing: excess phosphorus can actually increase your body's need for calcium. This can present a problem for people who drink bottle after bottle of cola soft drinks or who eat an abundance of processed foods which are often high in phosphorus.

New Soy Research

New research suggests that soy foods, like tofu or soy milk may be vital for preserving bones. A study of more than 60 postmenopausal women who consumed either diets rich in soy's isoflavones or milk protein found that eating soy restored calcium to some of the women's bones. Even though the researchers didn't think such a replacement due to soy was even possible!

The researchers at the University of Illinois believe that isoflavones behave in the body in some of the same ways that estrogen does. The study measured bone density at the lumbar spine, a part of the body at the small of the back that is liable to fractures due to osteoporosis.

Fluoride: Not Just For Teeth

Although most people associate the mineral fluoride with strong teeth, fluoride is just as important for bone strength. Surveys report that osteoporosis is reportedly less common in communities that drink fluoridated water. Fluoride combines with calcium in the bones to slow mineral loss after mid-life. Good sources of this mineral include fish, tea and most animal foods.

Cut Back on Alcohol and Coffee

According to the National Osteoporosis Foundation, consuming lots of caffeine is thought to increase the calcium excreted in your urine. In addition, high levels of protein and sodium in your diet are also believed to increase calcium excretion. And although more studies of protein and sodium are needed to precisely determine how these substances influence calcium loss you should limit the caffeine, protein and salt you take in.

On top of those findings, researchers say that the diuretic action of alcohol and caffeine speed skeletal calcium loss. They believe alcohol may interfere with intestinal absorption of calcium.

Pumping Up

Along with a bone-friendly diet, your exercise program should also be designed to preserve bone. Weight-bearing exercise-exercise that places stress on the bones-strengthens bone density and wards off osteoporosis. Weight-bearing exercises include weight lifting, walking, jogging and jumping rope.

Exercise possesses many benefits for preserving bone, according to Miriam Nelson, Ph.D., author of Strong Women Stay Young. Among them: exercise can help you retain the balance necessary to resist falls and strengthen the muscles that keep you erect. Studies performed on women of all ages found that by doing strength training exercises two times a week for a year, without use of estrogen or hormone replacement therapy (HRT), women, on average, added three pounds of muscle and lost three pounds of fat. They were also 75 percent stronger with improved balance and bone density.

Although strength training can be performed by anyone at any age, Nelson recommends that if you have an unstable medical condition or if you have recently undergone surgery, wait until you recover and speak with your doctor before beginning an exercise program. If you have not exercised in a long time, consult a health practitioner knowledgeable in sports medicine before beginning an exercise program.

Other Options

Drug therapies are now available to combat osteoporosis. One of the most popular is HRT, which supplies estrogen to women undergoing menopause. However, medical experts are still arguing over HRT 's possible role in increasing your risk of cancer, particularly breast cancer.

According to Jan Rattner-Heilman, co-author of Estrogen, the Facts Can Change Your Life, the conflicting studies that balance the benefits and risk of HRT are bound to confuse the average consumer. Estrogen is recommended to prevent bone loss and forestall heart disease and possibly Alzheimer's disease. Most women take estrogen to ease the discomforts of menopause such as hot flashes, and many experts do not believe that it unduly increases the risk of breast cancer for those at low risk.

Heilman warns, however, that estrogen probably should not be taken by women especially at risk for breast cancer risk or those who are already suffer the disease.

Patricia Q. is reluctant to try HRT. "I'm at risk for breast cancer-my mother had it-so I won't take estrogen. I'd rather do what I can without medications. My preference is to watch my diet and exercise as much as I can. That gives me my best chance to avoid osteoporosis."

Doctor Nelson agrees with this perspective She believes that exercise possesses enough benefits to make it the treatment of choice. "The difference between estrogen and strength training is that strength training has a huge spillover effect; you aren't just decreasing one type of disease. You become stronger with more muscles and less fat, and you become more fit. This decreases your chances for many types of diseases, not just osteoporosis. It can decrease risks for heart disease, diabetes, sleep disturbances, hypertension and more."

If you believe you are at risk for osteoporosis, ask your doctor about the benefits of bone mineral density screening. DEXA scan (dual energy x-ray absorptiometry) measures the bone density in a 15-minute test. But the test is expensive: the cost of this test ranges from $75-200 or more and may not be covered by your health insurance. But financial help may be on the way. A Bone Mass Standardization Act has been introduced in Congress to ensure that the cost of bone mass measurement is covered under Medicare and that standards for coverage are clear and consistent for anyone with medical insurance.

Fighting Osteoporosis at Different Ages

Childbearing years (30-40): These years are particularly important for preserving bone through exercise and good nutrition. Eat plenty of low-fat dairy products, vegetables and soy. Perform weight-bearing exercise such as walking, jogging and weight lifting to attain the greatest amount of bone and muscle possible. Being active reduces risk of injury and makes you stronger. If you smoke, now's the time to stop.

Menopausal years (late 40s-50s): During this time, muscle, bone and estrogen decreases. Minimize loss through diet, walking and weight lifting. Your exercise intensity may have to be decreased but you should not stop being physically active.

Post Menopause (over 60): Focus on reducing your risk of falling. Minimize balance problems and increase muscle strength through exercise.
