Vitamins and Minerals for AMD

Fortunately, scientists have found ways to combat AMD: An analysis of a study called the national Age-Related Eye Disease Study (AREDS) shows that more than 300,000 Americans could avoid losing their sight to AMD if they took daily supplements of antioxidant nutrients and zinc.

This conclusion, reached by scientists at Johns Hopkins' Wilmer Eye Institute, is based on research involving more than 4,500 adults suffering various stages of AMD. The study demonstrated that people who already had some AMD could lower their risk of the more advanced form of this condition by 25% when they took vitamin C, natural vitamin E and beta carotene along with zinc. Those suffering from advanced AMD lowered their chances of losing vision by about 19%. (Supplements did not affect the risk of cataracts or the chances of some vision loss for people in the early stages of AMD.)

" Without treatment to reduce their risk, we estimate that 1.3 million adults would develop the advanced stage of AMD," says Neil M. Bressler, MD, professor of ophthalmology at Johns Hopkins and author of the current study, published in Archives of Ophthalmology (11/03).

According to Dr. Bressler and the other researchers, people who now have intermediate AMD (some vision loss) in one eye have about a 1 in 16 chance of having their vision deteriorate until they have advanced AMD. They also calculate that about 1 in 4 of those with intermediate AMD in both eyes and 43% of those with advanced AMD in one eye will develop advanced AMD in five years without treatment.

In their view, older people at risk of AMD blindness should take daily supplements of 500 milligrams of vitamin C, 400 milligrams of natural vitamin E, 15 milligrams of beta carotene, 80 milligrams of zinc as zinc oxide and 2 milligrams of copper as cupric oxide. Evidence also exists that a diet which is high in fat can cause AMD to progress to an advanced stage. The exceptions: The healthy fats found in fish and nuts (Archives of Ophthalmology 2003; 121:1728-37).

Lutein Protection

Oddly enough, some of the same pigments that color vegetables and other foods also color your eyes. And scientists believe that those pigments, which are classified as carotenoids, help protect the eyes by helping them fight off the negative effects of caustic molecules called free radicals. Free radicals are formed when the energy from sunlight strikes the eyes and disrupts the composition of natural chemicals found there.

When scientists compared healthy eyes with eyes suffering from AMD, they found that AMD eyes contained lower levels of lutein and zeaxanthin, carotenoid pigments contained in egg yolk, spinach, broccoli and other dark green vegetables (Ophthalmology 2003; 109:1780). Furthermore, they found that levels of these chemicals generally decline as you grow older.

" This research is a major step toward large-scale clinical studies to prove the extent to which lutein and zeaxanthin protect against age-related macular degeneration," says Paul S. Bernstein, MD, PhD, at the University of Utah School of Medicine at Salt Lake. "We know that these carotenoids are specifically concentrated in the macula of the human eye."

Dr. Bernstein adds that, as you age, taking supplements containing lutein and other antioxidants may lower your AMD risk. In his investigation, people with AMD who did not take lutein had one-third less lutein in their eyes than older people whose vision was normal.

Avoiding Cataracts

Another eyesight hazard is cataracts, in which the eye's lens-the part that focuses incoming light onto the retina-becomes cloudy. Cataracts form when the proteins found in the normally clear lens become damaged; signs include progressively blurred vision (especially outdoors), focusing problems, seeing streaks of light from headlights and stoplights, and colors that look faded.

Cataract is the leading cause of blindness worldwide, according to the World Health Organization. One of every six Americans 40 and older suffers from some degree of cataract; it affects half of all Americans who reach age 80. Nuclear cataracts, the most common form of this disorder, develop in the center of the lens and tend to grow slowly. Cataracts may also develop at the back of the lens; this form is linked to eye trauma and long-term use of certain medications, including steroids.

Like AMD, cataracts become more common as people age. Up to 40% of individuals between the ages of 75 and 85 have them, compared with only 5% to 10% of those folks under the age of 65. And like AMD, sunlight exposure and smoking increase the risk of developing cataracts, as does the presence of diabetes.

Lutein and zeaxanthin, the carotenoids that are so plentiful in the macula, are also found in the lens (although in lower concentrations), leading many researchers to believe that these nutrients may help drop your risk of cataract development. Early studies indicate that an increased intake of lutein and zeaxanthin reduces one's chances of needing cataract surgery, the most common surgery in the United States (American Journal of Clinical Nutrition 1999; 70(4):509-16; 517-24).

Antioxidants and the Lens

Scientists believe that free-radical damage is a leading cause of cataracts, and so it isn't surprising that antioxidants have proved useful in preventing this problem.

Almost 500 women filled out diet questionnaires as part of a very large research effort called the Nurses' Health Study; those who had taken vitamin C supplements for 10 years or longer enjoyed the lowest rates of nuclear cataracts (Archives of Ophthalmology 2001; 119:1009-19).

So the answer to lowering your risk of eye problems is clear, whether you are already in your mature years or plan to be someday: Lead a healthy, eye-friendly lifestyle, eating a diet filled with colorful fruits and vegetables. Take frequent walks and jogs around the block.

And yes, when you kick back and take your just-as-frequent doses of antioxidant supplements, you're allowed to take your sunglasses off and see the world clearly.

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: Eat to Live - fruits and vegetables are more effective than foods like ...

Eat to Live by Mary Menendez Energy Times, April 14, 2004

By now, most everyone with even a cursory interest in health knows that fruits and vegetables are more effective than foods like cheeseburgers at making your body more resistant to chronic diseases such as cancer.

But beyond that generality, few people seem to know how to fine-tune their meals for the most anti-cancer bang per bite.

Over the course of the lifetime of planet Earth, the plant world has devised and concocted a wealth of nutrients that can help your body fight off cancer.

It's time to put them to work for you.

Would you be interested in a tasty, quick way to cut your chances of certain types of cancer in half? The means to this desirable end are about as close as your refrigerator and your dining room table: All you have to do is cut open and eat a single orange every day.

According to cancer research in Australia, adding that extra serving of citrus fruit to your diet every day, only once a day, boosts immunity enough to significantly lower your risk of some common cancers.

" Citrus fruits [protect] the body through their antioxidant properties and strengthen the immune system, inhibiting tumor growth and normalizing tumor cells," says Katrine Baghurst, PhD, of the Commonwealth Scientific and Industrial Research Organization (CSIRO). According to Dr. Baghurst and her fellow researchers, oranges possess the most antioxidants of any fruit: more than 170 different phytochemicals.

The protection you can get from oranges is due to their influence on immunity. Your immune system has the assigned task of protecting you against cells that can turn cancerous. Sixty of the chemicals in oranges are substances called flavonoids that can help the immune system fend off inflammation and tumors.

Better Vegetables

When Americans eat fruits and vegetables, they don't eat the ones with the most anti-cancer (or other) health benefits. Instead, we dine on the same so-so produce too frequently. If we want more health benefits from our veggies, we'd better look to expand our culinary horizons.

" While people understand they should eat a variety of fruits and vegetables each day, they are not translating 'variety' in a way to capture health benefits, such as reducing their risk of developing chronic diseases," says Susie Nanney, PhD, acting director of the Obesity Prevention Center at Saint Louis University.

" People aren't eating the fruits and vegetables that contain the most nutrients," warns Dr. Nanney. "People are quite frankly confused about nutrition. I feel their pain."

Unfortunately, Americans rely too often on iceberg lettuce, corn, apples, potatoes and bananas; a steady diet of that produce doesn't produce the same benefits as indulging in a wider variety of vegetarian foods.

Dr. Nanney points out that the vegetables and fruits most effective at helping the body fight cancer are dark green leafy veggies, citrus (oranges, grapefruits), cruciferous vegetables (broccoli and cauliflower) and produce that has yellow or orange color.

Making Dinner Plans

Dr. Nanney's spectrum of desirable foods includes:

Desirable Diet

" When we look at how to get the most bang for your buck, the most power, it's by eating these other fruits and vegetables instead of the traditional choices," Nanney insists.

Studies show that tomatoes, colored by a pigment called lycopene, may be particularly helpful in lowering men's chances of prostate cancer. For instance, research on about three dozen men with prostate cancer found that those taking supplements of lycopene and other tomato phytochemicals had smaller tumors and less spread of their cancers (Exper Bio and Med, 2002; 227: 881).

The researchers conclude that "lycopene may have an antitumor effect and may be useful as an adjunct to standard treatment of prostate cancer, such as surgery, radiation therapy, hormones and chemotherapy. In addition, lycopene supplementation appears to have reduced the [spread of cancer within the prostate], suggesting that lycopene may have a role in the prevention of prostate cancer."

In a study on African-American men, who suffer a higher rate of prostate cancer than other Americans, researchers also found that lycopene can limit the DNA damage that may presage cancer (Amer Chem Soc Meeting #222, 2001).

" This study does not say that tomato sauce reduces cancer," cautions Phyllis E. Bowen, PhD, a nutritionist at the University of Chicago and lead investigator in the study. " It says that it reduces DNA damage that we think is associated with cancer."

Tomato Consumption

Other studies have confirmed the finding that men who eat tomatoes suffer less prostate cancer. And if you want the most anti-cancer benefit from tomatoes, better cook them.

According to Rui Hai Liu, MD, Cornell assistant professor of food science, "[Our] research demonstrates that heat processing actually enhanced the nutritional value of tomatoes by increasing the lycopene content-[the] phytochemical that makes tomatoes red-that can be absorbed by the body, as well as the total antioxidant activity. The research dispels the popular notion that processed fruits and vegetables have lower nutritional value than fresh produce."

Less Meat

While you're making an effort to eat more of the colorful vegetables, you should also eat less fatty red meat and cut back on high-fat dairy foods, according to research from Harvard.

In this study, which covered eight years and looked at the diets of more than 90,000 women, scientists found that those premenopausal women who ate the most fatty red meat and regular milk had the highest chance of developing invasive breast cancer.

The scientists taking part in this study believe that eating more saturated fat from meat may increase hormone levels that boost the chances of breast cancer (Jrnl Natl Cancer Inst 2003;95:1079).

In this research, the total amount of fat didn't affect cancer risk, but the amount of animal fat did. Women who ate the most red meat had a 54% higher chance of breast cancer. Aside from avoiding red meat, women who wish to lower their risk of breast cancer should also limit their consumption of alcoholic beverages.

A study of two thousand post- menopausal women found that those who averaged about two drinks a day raised their risk of breast cancer by about 80% (Cancer Epidem, Biomarkers and Prevention, 10/03).

Here, too, researchers believe that alcohol affects the level of hormones that influence cancer.

The moral of the research into how food can slow cancer risk: Eat a wide variety of vegetables and fruits early and often. Limit meat and alcohol.

Change the color of the fruits and vegetables on your plate for a better chance of a brighter future.

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.

Subject: Home on the Range

Home on the Range

by Janis Jibrin, RD Energy Times, September 5, 1999

Got chicken? Americans can't seem to get enough of this bird. Last year each of us ate, on average, just about 80 pounds of chicken, a whopping increase over the 49 pounds we each devoured in 1980 and an eight-pound increase from 1995. Part of this food's popularity comes from its lean image as a healthier, less fatty alternative to red meat (don't forget to take the fatty skin off). Chicken's also a cheap protein source: At many popular supermarkets you'll find weekly specials at about a dollar a pound.

But at health food markets, chicken can cost upwards of $1.69 a pound. These birds may be touted as raised in an organic, stress-free environment and on a vegetarian diet, free of antibiotics. For many people, this poultry is a better buy.

The Alternative Chicken

Most of the supermarket chicken you pick up in grocery refrigerated cases are broilers, birds bred to mature in about eight weeks. In comparison, in the '60s, chickens needed 14 weeks to become adult poultry. Conventionally-raised broilers eat grain mixed with whatever's cheapest on the market, such as recycled cooking oil that's been used to fry fast foods and animal parts.

These birds reside in chicken coops the size of football fields and don't see the light of day until transported to the slaughterhouse. On the other roost, alternatively raised chickens are brought up in a variety of ways (see box), but usually enjoy a more relaxed life and diet.

Chickens on the farm receive antibiotics for two reasons: To fight off the diseases that can run rampant through a crowded chicken coop and to encourage faster growth.

Antibiotics Stimulate Growth

Mark Cook, PhD, professor of animal science at the University of Wisconsin at Madison, explains, "Gut bacteria trigger an immune system assault, which makes chickens a little feverish, suppresses appetite and slows growth. Antibiotics stimulate growth indirectly, by keeping bacteria levels down, and preventing the immune reaction." When birds get sick, they often get dosed with even more antibiotics.

This widespread antibiotic use has come home to roost and may contribute to the growth of bacteria that, frequently exposed to chemicals, have evolved ways to keep from being killed by pharmaceuticals.

This development threatens human health. Bacterial infections that people contract, once easily cured by penicillin or other drugs, are now tougher to eradicate. For instance, campylobactor, a common bacteria found in chicken, and responsible for some food poisonings, now demonstrates signs of resistance to drugs like floroquinolones. A powerful class of antibiotics, floroquinolones used to dependably conquer this infection.

"Floroquinolones are an extremely important class of antibiotics, used to treat many types of infections such as urinary tract infection, a wide variety of gastrointestinal illnesses, pneumonia, almost everything," says Kirt Smith, DVM, PhD, epidemiologist, acute disease epidemiology section, Minnesota Department of Health.

A study by Dr. Smith, published in the New England Journal of Medicine (340, 1999: 1525-32), showed that the percent of floroquinolone-resistant campylobactor appearing in infected people in his state-Minnesota-climbed from a little over 1% in infected people during 1992 to 10.2% in 1998. He and other scientists strongly suspect that the rise is a direct consequence of the Food and Drug Administration's (FDA) decision to allow floroquinolones in poultry feed beginning in 1995.

Although it was nearly impossible for Dr. Smith to trace the precise origin of campylobactor poisoning, he believes chicken was usually the source-and not just U.S. chicken. Many of the infected people had returned from Mexico and other countries.

"Sales of floroquinolones for poultry use in Mexico has increased dramatically," notes Dr. Smith.

Many alternative chicken producers do not use any antibiotic-laced feed at all. Other farmers adjust the feed to lower gut pH, making it more acidic and lowering chances of bacteria. At the U. of Wisconsin, Dr. Cook is developing antibodies to suppress the immune response to bacteria so chickens won't need antibiotics to spur growth. Buying and dining on chicken raised with little or no antibiotics could beneficially lower your risk of contracting a hardy bacterial infection. Better to catch campylobactor from an antibiotic-free chicken than a conventional chicken, speculates Dr. Cook. "There's less likelihood the bug will be resistant, and a better chance your problem can be cured with antibiotics," he explains.

And, looking beyond your own immediate health risk, buying antibiotic-free chicken makes a small contribution to stopping the spread of antibiotic resistant bugs. A Matter of Taste Conventionally raised chickens get little exercise and live only eight weeks, so they're tender but bland.

"There's not much taste in a modern chicken. Free range or organically grown, older birds usually have more taste," notes Dr. Cook.

The days of barnyard chickens happily clucking and strutting around in picturesque nature have disappeared with the family farm. Today, chickens lead a meager existence. After hatching, baby chicks are tossed into a gigantic hen house that is home to up to 30,000 birds. Their short lives are lived within the United States Department of Agriculture (USDA) mandated 3/4 square foot per chicken. In that squeeze, birds can catch "chicken influenza," especially in winter when it's too cold to let in much fresh air.

Laying hens don't experience much more of a peaceful existence. These birds live their years with about five other hens, so crowded they can't flap their wings. Cages, suspended in the air, let eggs roll into a holding area. So they don't peck each other, hens are often debeaked, a painful process that can cause infection.

Hens go through natural laying and "dry" cycles. Growers manipulate this cycle by "forced molting," depriving hens of food for four to 14 days to keep them constantly laying. By the end of two years, hens are worn out. Their inactivity weakens their bones enough that electrical stunning, the usual method for knocking chickens out before slaughter, shatters their bones. So some wind up being plucked and boiled alive, according to Mary Finelli, program director for farm animals and public health at the Humane Society of the United States. The meat from these hens, tougher than other birds, was probably in your deli lunch sandwich. It's also used in the school lunch program or may end up in dog food.

"Generally, organically-grown broilers and hens have it better because room to move is part of the organic certification process," says Finelli. Finelli suggests visiting chicken suppliers to find out how chickens are treated. Or, she advocates a Humane Society book listing reliable firms. For a local producer call the society: 202-452-1100. According to a Consumer Report report, some growers force chickens out the last week of their lives to brand them "free range." So free range isn't a prime standard for choosing a decently raised chicken. However, turkeys thrive outdoors, so choosing free-range turkey is often a good idea for better tasting poultry.

In any case, organic is your best bet for chicken without pesticides. Make it your main choice for your 80 pound yearly consumption!

To fight cruel treatment of poultry:

• Forced Molting Ban. Forced molting is shocking hens for more eggs. To support petitions banning forced molting write: Docket Manage-ment Branch, FDA, Dept. Health & Human Serv-ices, 12420 Parklawn Drive, Room 1-23, Rock-ville, MD 20857. Include docket # 98P-0203/CP

• Downed Animal Protection Bill (House Bill 443, Senate Bill S515) spares some animals from the tortuous journey from chicken house to slaughterhouse. Mandates humane euthanization.

Subject: Cancer at the Millenium - the war on cancer entering its third decade...

Cancer at the Millenium by Harriet Brown Energy Times, May 1, 1999

With the war on cancer entering its third decade, the necessity grows clearer for medical science to engage the enemy on several fronts. Until recently, high-tech medical weapons like vaccines and gene therapy, inspired by a flood of insights into the molecular basis of cancer, garnered most of the hope, hype, headlines and research money. The science was sexy and the prospect of a "cure" dramatic. But, today, advocates of prevention receive equal, if not greater, attention.

Improving our diets and prudently supplementing with vitamins and minerals, can deliver a major preventive impact. Contentious experts concede that at least a third (and probably more) of all cancers can be blamed on a combination of eating too much of the wrong foods and not enough of the right ones.

The Dietary Difference

Though cancer can progress rapidly once it leaps past its inception, it develops over many years and in several stages. Beneficial compounds in food and supplements may intervene along a line that runs from initial exposure to carcinogens to the final step into outright malignancy. Nutrients may: - counteract environmental poisons and the toxic byproducts of liver metabolism

The Big Picture The dietary guidelines advocated by the American Cancer Society and the National Cancer Institute (which generally coincide with those of most health organizations) may sound familiar: Eat plenty of fruits and vegetables. Get lots of fiber. Limit fat, especially animal fat. Go easy on meat and avoid the cured variety (they contain nitrites). If you drink alcohol, do it in moderation. Watch your total calories, and your weight. Pretty straightforward stuff.

Carotenoid Characteristics

Carotenoids, as their name suggests, are orange and red pigments in fruits and vegetables, most notably carrots and tomatoes, although they're also in everything from sweet potatoes to spinach and brussels sprouts (in the latter their distinctive color is masked by green chlorophyll).

Lycopene, a carotenoid found primarily in tomatoes, displays double the free radical-fighting activity of beta carotene, the most widely studied carotenoid. Of 72 studies looking at consumption of tomatoes or tomato-based products reviewed in the February 1999 Journal of the National Cancer Institute, almost half showed a significant reduction in one or more of a variety of cancers.

Research shows that lycopene may be best at lowering a man's risk of prostate cancer. A 1995 Harvard Medical School study (Journal of the National Cancer Institute 1995; 87: 1767-76) queried nearly 48,000 male health-care professionals about their consumption of fruits and vegetables. The only foods that reduced their risk of prostate cancer were, apparently, tomato sauce, tomatoes, pizza (tomato paste). For those who ate ten servings a week, risk dropped 45 percent; with four to seven servings, 20 percent. In animal studies lycopene decreased the number and size of mammary tumors (Eleventh International Symposium on Carotenoids, 1996).

Tomatoes are one of the richest sources of lycopene. Cooking tomatoes helps by releasing the lycopene from the plant cell walls. Also, the oil in tomato sauce enhances absorption in the stomach. Lycopene is also available in supplements.

Unreserved Resveratrol

Wine drinkers rejoiced when resveratrol, a constituent of the skin of red grapes, was found to protect their hearts (by blocking oxidation of LDL cholesterol and discouraging blood clotting). Now they have another reason to toast this potent antioxidant. When researcher John Pezzuto at the University of Illinois at Chicago screened about 1,000 plants for anticancer activity, he came up with one whose active ingredient turned out to be resveratrol. In lab tests it squelched both free radicals and inflammation, two well-known cancer inducers (Science, 6/10/97). In a study with mice, resveratrol reduced the number of skin tumors by up to 98 percent compared to control animals. Because the effective doses were high (Pezzuto estimates a person would have to quaff about five gallons of wine a day to get the equivalent) and because more than a drink or two a day may raise the risk of breast cancer, researchers don't recommend nondrinkers take up wine. But supplements of synthesized resveratrol (as well as grape juice) may help.

Fat Chance

Saturated fat is an authentic dietary villain. Aside from clogging arteries, it's a suspected contributor to several cancers, though the evidence is greater for some cancers (prostate) than for others (breast cancer)

Of the two other main categories of fats, monounsaturated and polyunsaturated, mono seems benign, if not positively protective. For example, in a study of the influence of diet on breast cancer, Greek researchers discovered that women who consumed higher amounts of olive oil (which is mostly mono) were less likely to be afflicted with breast cancer (Journal of the National Cancer Institute 1995: 87; 110-116).

When it comes to polyunsaturated fats, however, things get complicated. The fat that predominates in corn, sunflower and other vegetable oils, called omega-6, has long been associated with cancer risk in animal experiments. Likewise the type found in margarines, trans fats, which are partially saturated vegetable oils. On the other hand, the omega-3 fats called EPA and DHA, which are found primarily in deep- and cold-water fish like cod, mackerel, and halibut, protect against both heart disease and cancer. In an epidemiological study covering 24 European countries, British researchers established that mortality rates for colon and breast cancers declined as fish and fish oil consumption rose (British Journal of Cancer 1996: 74; 159-64). And Finnish scientists discovered that the breast tissue of women who had breast cancer contained significantly less DHA and EPA than the breasts of healthy women (Nutrition and Cancer 1995: 24; 151-160).

Experts believe the omega-3s' anticancer effect derives from its ability to tamp down the prostaglandins that stimulate inflammation. Chronic inflammation unleashes a steady stream of free radicals, which can damage DNA and thereby trigger cancer. Omega-3s also help the liver detoxify potentially harmful substances.

Fortunately for the fish-phobic, nonmarine sources of omega-3 fats include flaxseed and hemp oils.

Minerals to Lower Cancer risk

n Calcium: possibly protective against colon cancer. In a recent trial (New England Journal of Medicine, 1/14/99) researchers gave people with a history of precancerous colon polyps either two 600 mg calcium tablets a day or a placebo for nine months and found fewer polyps. n Selenium: powerful antioxidant and supporter of immunity. Researchers find that cancer rates in various regions is lowered when soil and vegetables contain more selenium

In a selenium-depleted area in China afflicted with one of the highest incidences of stomach and esophageal cancer mortality in the world, scientists asked different groups to take various combinations of nutrients. After five years they found a significant reduction in the cancer rate among those who had gotten supplements of selenium, vitamin E and beta carotene (Biological Trace Element Research 1985; 7: 21-29). In the U.S. researchers studying the potential effectiveness of selenium supplementation for preventing nonmelanoma skin cancers came up with a surprise. The 200 mcg a day the subjects received for an average of 4.5 years had no impact on skin cancer but did significantly cut the rates of lung, colorectal and prostate cancers (Journal of the American Medical Association, 12/25/96).

More recently Harvard researchers determined that men with prostate cancer had much lower levels of selenium in their toenails (a measure of consumption) than healthy men (Journal of the National Cancer Institute, 8/119/98).

Cruciferous Vegetables

Cruciferous vegetables like broccoli, brussels sprouts, cauliflower and kale, have long been singled out for their association with protection against cancer. In a 1996 survey of 94 population studies and clinical trials focusing on consumption of cruciferous vegetables, 67 percent showed a reduced risk, the strongest link being with lung, stomach, colon and rectal cancers (Cancer Epidemiological Biomarkers 1996; 5: 733-748).

Scientists at Johns Hopkins showed that sulforaphane, from these plants, stimulates enzymes that help detoxify carcinogens generated in the liver. When they injected rats with a cancer-causing chemical, only 26 percent of the rodents pretreated with sulforaphane developed mammary cancer, compared to 68 percent of controls. Even animals who did come down with cancer had tumors that appeared later and smaller.

Other researchers have focused on a cruciferous-vegetable compound called indole-3-carbinol, which has proved especially effective against breast cancer cells. Recently, scientists at the University of California at Berkeley found that indole-3-carbinol, rather than acting as an anti-estrogen, (as had been thought), actually stops breast cancer cells by turning off a protein critical to their replication (Jrnal of Bio Chem, 2/13/98). Consequently, when treating certain forms of cancer, some doctors have paired indole-3-carbinol with the chemotherapy drug tamoxifen - which counteracts estrogen - and found that the combination has proven more potent than either separately.

Fiber

Several decades ago British physician Denis Burkitt proposed that the low incidence of colon cancer among native peoples in South Africa was attributable to the fact that their diet was rich in fiber. The fiber, it was hypothesized, bulked up the stool, speeding its passage through the bowel and reducing the time carcinogens contact its lining; it also helped neutralize cancer-promoting bile acids.

This concept has been backed up by numerous studies. Recently, Harvard researchers sprinkled cold water on this idea, finding that an examination of the eating habits of more than 80,000 female nurses, could find no protective effect against colon cancer or precancerous polyps from consuming fiber (NEJM, January 21, 1999). Most experts' take on this apparent refutation: Maybe the "high fiber" intake in this case wasn't high enough, and this is just one study among many.

Fighting Breast Cancer

Fiber has also been linked to reduced rates of breast cancer. At first it was thought that if fat was a breast-cancer culprit, fiber might just be a marker for a low-fat diet. But a look at Finland undermined that idea: Finnish women eat both a lot of fat and a lot of fiber, and their breast cancer rate ranks much below that in the U.S., (where we eat gobs of fat and little roughage).

Fiber helps take estrogen out of circulation as it passes through the liver, while the isoflavones in many high-fiber plants and vegetables are themselves weak estrogens, which compete for slots on breast tissue's estrogen receptors. The special fiber in flaxseed oil called lignans act against estrogen in two ways: by binding its receptors and by inhibiting the enzyme that converts other hormones into estrogen.

Fiber comes in two basic forms, insoluble (e.g., wheat bran, celery, the skins of fruits and vegetables) and soluble (e.g., oat bran, citrus fruits, beans). Until a few years ago, scientists believed that cancer protection came mainly from insoluble fiber, but that thinking has turned around.

A soluble fiber called citrus pectin has been shown to halt the tendency of prostate, lung, breast and skin cancers to metastasize, or spread (e.g., Journal of the National Cancer Institute 1995; 87: 3448-353). Typically cancer turns deadly only when it gets into the bloodstream and invades new territory. Modified citrus pectin appears to stop this aggression by preventing cancer cells from attaching to healthy tissue.

Novel Antioxidant

While the name inositol hexaphosphate (IP6) sounds like a mouthful, many of us consume mouthfuls of this natural substance every day - in foods like corn, rice, whole-grain cereals, oats and wheat.

But now scientists have isolated IP-6 and found that this powerful antioxidant can slow the destructive cellular processes that lead to tumors. In a study published in Anti-Cancer Research (Nov/Dec 1998), scientists at the University of Maryland School of Medicine demonstrated that IP-6 could shrink liver tumors in laboratory animals.

The researchers believe that IP-6 can help prevent cancer and also be useful in lowering the risk of health problems like kidney stones and heart disease. Research like this continues to expand our knowledge of how to lower the risk of cancer. In the next millennium, with more and more information making its way into the media and onto websites, our power and the responsibility to reduce our risk of cancer will continue to grow and offer new possibilities.

Subject: Recognizing the Signs: Roadmap to a Healthy Heart

Recognizing the Signs: Roadmap to a Healthy Heart by Louis McKinley Energy Times, January 2, 2004

From time immemorial, people have tuned into life's lessons that come from the heart. Sadly, times are changing: If you're like most inhabitants of today's harried world, you may be too distracted to detect important clues about your cardiovascular circumstances.

And while heart lessons may be more complicated than simply connecting the physiological dots, understanding those heart messages are imperative for improving and maintaining your heart health.

Every cell in your body relies on heart-powered blood flow to keep it supplied with nutrients, oxygen, hormones and other natural chemicals necessary for survival. Without that supply of life-giving substances, few cells in the body-including those within the heart itself-can survive very long.

And just as damage to a major roadway can cause mayhem with traffic patterns, damage to blood vessels and the heart can wreak a lumpy cardiovascular havoc that blocks the passage of blood and endangers your heart's well-being.

Your Heart Disease Chances

Within the last ten years, scientific research performed by investigators around the world has focused on the specific factors that most strongly influence your chances of developing heart disease and suffering either a heart attack or a stroke.

While much of your risk depends on your genetic inheritance and family history, several factors that determine your heart health are within your control.

The most important factors you can do something about include:

* Smoking: free radicals generated by burning tobacco causes significant damage to blood vessels and other cells

* Lack of exercise: the human body is designed for consistent, moderate physical activity; without exercise, the body slacks off in creating antioxidant protection for arteries

* Diabetes: when excess blood sugar persists, physiological processes begin that endanger the heart and arteries

* Cholesterol: when oxidized (a chemical process that has been compared to a kind of internal rusting), cholesterol can form artery-blocking plaque; antioxidant nutrients like vitamin C and natural vitamin E may help the body limit this process

* High blood pressure: excessive pressure within the blood vessels raises the risk of damage to the heart and arteries; a program of weight loss and exercise can help control blood pressure

* Being overweight: the extra body fat carried around your middle is linked to a greater risk of heart problems

Heart Attack Signs

Do you think you know what a heart attack feels like? Well, if you think it feels like a dramatic pain somewhere in your chest that knocks you to the floor, you're probably wrong. "Most heart attacks do not look at all like what one of my colleagues calls the 'Hollywood' attack-the heart attack you see on television or in the movies," warns Julie Zerwic, MD, professor of surgical nursing who has studied what happens when people develop heart disease and suffer damage to their hearts.

"The symptoms [of heart problems] are not necessarily dramatic. People don't fall down on the floor. They don't always experience a knife-like, very sharp pain. In fact, many people describe the sensation as heaviness and tightness in the chest rather than pain," she says. And, if you're a woman experiencing a heart attack, you may not even feel discomfort specifically in your chest. Instead you may experience a severe shortness of breath. The apparent ambiguity of the discomforts caused by a heart attack lead many people to either ignore them or take hours to realize they need to go to the emergency room at the hospital.

Consequently, much fewer than half of all individuals undergoing a heart attack actually go to a hospital within an hour of the start of the attack. That delay can be a fatal mistake.

"Timing is absolutely critical," laments Dr. Zerwic. "If treatment starts within a hour after the onset of symptoms, drugs that reestablish blood flow through the blocked coronary artery can reduce mortality by as much as 50%. That number drops to 23% if treatment begins three hours later. The goal is to introduce therapy within two hours."

However, in Dr. Zerwic's research, only 35% of non-Hispanic whites go to the hospital within an hour of the start of a heart attack. And among African-Americans, the number of people going to the hospital right away drops to a frighteningly low 13%.

Often, people will lie down or use a heating pad to relieve the tightness they feel in the chest," says Dr. Zerwic. "They may take some medicine and wait to see if that works. All these steps postpone needed treatment."

Signs of a possible heart attack include:

* Chest discomfort: Heart attacks most frequently cause discomfort in the center of the chest that can either go away after a couple of minutes (and come back) or persist. The discomfort may feel like strong pressure, fullness or pain.

* Upper body discomfort: An attack may set off pain or discomfort in either or both arms, and/or the back, neck, jaw or stomach.

* Shortness of breath: Chest discomfort is frequently accompanied by shortness of breath. But it's important to note that shortness of breath can take place even in the absence of chest discomfort.

* Other signs: You can also break out in a cold sweat, or feel nauseated or light-headed.

A Woman's Sleep Signs

If you are a woman who suddenly experiences a marked increase in insomnia and puzzling, intense fatigue, you may be in danger of an imminent heart attack.

In an attempt to understand how women's symptoms of heart problems differ from those of men, researchers talked to more than 500 women in Arkansas, North Carolina and Ohio who had suffered heart attacks. (Technically, what they had experienced is referred to as acute myocardial infarction.)

They found that chest pain prior to a heart attack was only reported by about 30% of the women surveyed.

More common were unusual fatigue, sleep disturbances and shortness of breath (Circulation Rapid Access, 11/3/01).

"Since women reported experiencing early warning signs more than a month prior to the heart attack, this [fatigue and sleep problems] could allow time to treat these symptoms and to possibly delay or prevent the heart attack," says researcher Jean C. McSweeney, PhD, RN, nursing professor at the University of Arkansas for Medical Sciences in Little Rock. In Dr. McSweeney's study, more than nine out of ten women who had heart attacks reported that they had had new, disturbing physical problems more than a month before they had infarctions.

Almost three in four suffered from unusual fatigue, about half had sleep disturbances, while two in five found themselves short of breath.

Other common signs included indigestion and anxiety.

"Women need to be educated that the appearance of new symptoms may be associated with heart disease and that they need to seek medical care to determine the cause of the symptoms, especially if they have known cardiovascular risks such as smoking, high blood pressure, high cholesterol, diabetes, overweight or a family history of heart diseases," says Dr. McSweeney.

Dr. McSweeney warns that, until now, little has been known about signs that women are having heart trouble or heart attacks. The fact that most of Western medicine's past attention has been on heart problems in men has obscured the warning signs in women. As part of Dr. McSweeney's studies, she and her fellow researchers have discovered that more than 40% of all women who suffer a heart attack never feel any chest discomfort before or during the attack.

"Lack of significant chest pain may be a major reason why women have more unrecognized heart attacks than men or are mistakenly diagnosed and discharged from emergency departments," she notes. "Many clinicians still consider chest pain as the primary symptom of a heart attack."

Vitamins for Diabetes and Heart Disease

Having diabetes significantly raises your chance of heart disease, which means that keeping your blood sugar levels under control can reduce your chances of suffering a heart attack.

Today, 17 million Americans have diabetes and, as the country's population in general gains weight and fails to exercise, the number of people suffering this problem continues to grow.

The first line of defense against diabetes consists of exercise and weight control. All you have to do is take a brisk walk for 30 minutes a day to drop your chances of diabetes (American Journal of Epidemiology 10/1/03).

"We have found that men and women who incorporate activity into their lifestyles are less likely to develop type 2 diabetes than those who are sedentary. This finding holds no matter what their initial weight," said Andrea Kriska, PhD, professor of epidemiology at University of Pittsburgh Graduate School of Public Health.

To help your body fight the development of diabetes, researchers also recommend vitamin C and natural vitamin E.

Researchers working with lab animals at the University of California at Irvine have found that these antioxidant vitamins can help insulin (the hormone-like substance secreted by the pancreas) reduce harmful blood sugar. In addition, these vitamins shrink the chances of organ damage that can be caused by diabetes (Kidney International 1/03).

In this investigation, these vitamins also helped reduce blood pressure, another risk factor that raises heart disease risk.

"Blood pressure was lowered to normal, and free radicals were not in sufficient numbers to degrade the sugars, proteins and nitric oxide," notes Nick Vaziri, MD, professor of medicine at the University of California. "We think this shows that a diet rich in antioxidants may help diabetics prevent the devastating cardiovascular, kidney, neurological and other damage that are common complications of diabetes."

Free Radical Blues

Dr. Vaziri and his group of researchers found that untreated diabetes raised blood pressure and increased the production of free radicals, caustic molecules that can damage arteries and the heart. Free radicals can change blood sugar and other proteins into harmful substances, boosting tissue and heart destruction.

In Dr. Vaziri's work with lab animals, he found that treating diabetes with insulin lowered blood pressure and helped keep sugar and protein from changing into dangerous chemicals, but allowed the free radicals to subvert nitric oxide, a chemical the body uses to protect itself from free radicals.

In this investigation, adding vitamins C and E to insulin insulated the body's sugars, proteins and nitric oxide from oxidative assault. This produces a double advantage: Lowering the risk of heart disease and other damage to the body from diabetes.

Maitake, an Oriental mushroom that has been shown to have many health benefits, can also be useful for people with diabetes who are trying to avoid cardiovascular complications. Laboratory studies in Japan demonstrate that maitake may help lower blood pressure while reducing cholesterol (Biological & Pharmaceutical Bulletin 1997; 20(7):781-5). In producing these effects, the mushroom may also help the body reduce blood sugar levels and decrease the risk of tissue damage.

No Smoking!

Tobacco smoke is one of the most notorious causes of heart problems. In the same way a hard frost exerts a death grip on a highway, the smoke from cigarettes can freeze up arteries and hamper their proper function. A healthy artery must stay flexible to comfortably allow adequate circulation.

But "...when blood vessels are exposed to cigarette smoke it causes the vessels to behave like a rigid pipe rather than a flexible tube, thus the vessels can't dilate in response to increased blood flow," says David J. Bouchier-Hayes, MD, professor of surgery at the Royal College of Surgeons in Ireland, who has studied the deleterious effects of tobacco.

This rigidity is called endothelial dysfunction. When arteries are rigid, blockages gum up vessels, clots and other impediments to blood flow appear, and your risk of heart attack and stroke increases (Circulation 2001 Nov 27; 104(22):2673).

This condition can also cause chest pain (angina) similar to that caused by a heart attack, and should be evaluated by a knowledgeable health practitioner.

Although all experts recommend you stop smoking to lower your heart disease risk, some studies have found that Pycnogenol(r), a pine bark extract that helps the body fight inflammation, may ease some of smoking's ill effects.

In a study of platelets, special cells in the blood that can form dangerous blood clots, researchers found that Pycnogenol(r) discouraged platelets from sticking together (American Society for Biochemical and Molecular Biology 5/19/98). By keeping platelets flowing freely, this supplement may alleviate some of the heart-threatening clots that tobacco smoke can cause.

In Ayurvedic medicine, a traditional therapy from India, an herb called guggul has also been used to lower the risk of blockages in arteries. This herb, derived from the resin of the mukul tree, has been shown to reduce cholesterol by about 25%. People taking this herb have also reduced their triglycerides (harmful blood fats) by the same amount (Journal Postgraduate Medicine 1991 37(3):132).

The Female Version of Heart Disease

Cholesterol and Heart Health
Controlling cholesterol (as mentioned before), the fat-like material running around your blood that can block arteries, is considered crucial for protecting your cardiovascular system. A new tool in the cholesterol battle is a natural substance known as potassium hydrogen d-glucarate, a chemical which your body makes and is found in fruits and vegetables. Studies on research animals have shown that potassium hydrogen d-glucarate can lower blood cholesterol, even lowering LDL ("bad" cholesterol) by more than a third. Noni, made from a tropical fruit, is another natural substance attracting attention as a possible helper for heart health and other chronic conditions. Traditionally, noni has been used to treat a wide variety of problems, including intestinal difficulties and arthritis. While some researchers are looking into its anticancer properties, it is reputed to help lower blood pressure and function as an adaptogen, boosting the body's ability to resist infection and deal with stress.

Nuts and Heart Health
Back in the early days of nutritional advice for heart health, some experts recommended against eating nuts: After all, they are high in fat and it was thought that high fat diets could compromise the function of your cardiovascular system. However, studies of people who go nuts for nuts and who eat walnuts, cashews, pecans, macadamias, pistachios, almonds and more found these nut lovers suffer less heart disease than non-nut consumers. Part of the good news about nuts, researcher believe, derives from the mineral magnesium found in nuts (and also contained in leafy green vegetables, legumes and whole grains). A magnesium deficiency may contribute to heart problems. In addition, the fats in nuts are monounsaturated, the same kind of heart-healthy fats found in canola and olive oils. Within nuts are also found a good deal of fiber, flavonoids and other natural substances that seem to protect the heart and arteries. Consequently, research indicates that if you eat nuts every weekday you may reduce your risk of heart problems by about two-thirds (Nut Rev, 2001;59:103-111). Of course nuts aren't the only vegetarian way to stay heart healthy. Foods such as oatmeal which are rich in soluble fiber, fiber that can be dissolved in water, also may lower your cholesterol. In addition, plant compounds known as sterols can improve your cardiovascular well-being. Researchers have been looking at these natural chemicals for the last 50 years and have found that they can significantly drop cholesterol (Am J CLin Nut 1995;61:392-396).

Vegetarianism vs Heart Disease
A vegetarian diet, in general, conveys more health benefits than eating meat. (Though fish, which contain heart-healthy omega-3 fatty acids, also lowers the risk of circulatory disorders.) In addition, mushrooms are attracting more attention from researchers as possible sources of heart-helping compounds. In Japan, for instance, health practitioners use the maitake mushroom for treating high blood pressure and lowering cholesterol. (If you suffer from cardiovascular abnormalities, consult your health practitioner.) Maitake has already established a growing reputation for possibly fighting cancer (Cancer Prev 9/30/95;768:243-245). Adjusting to the latest advice on protecting your heart doesn't require radical changes in lifestyle. A touch of exercise, a spattering of heart-healthy nutrients: Before you know it, you can be headed down cardio road and heir to a cardiovascular system that systematically functions better than ever.

Subject: new treatment options for chronic hepatitis

Can science meet the challenges of the HCV pandemic: new treatment options for chronic hepatitis C. Roehr B Journal of the International Association of Physicians in AIDS Care (1998 Jul), 4(7), 24-9. Journal code: 9508185. ISSN:1081-454X. United States. (NEWSPAPER ARTICLE) written in English. PubMed ID 11365638 AN 2001282246 MEDLINE

Abstract

New treatment options for chronic hepatitis C (HCV) infection are examined. Studies show the efficacy of interferon alfa-2b in normalization of serum alanine aminotransferase and histological improvement in necroinflammatory liver disease. However, 70 to 80 percent experiencing normalization usually relapse within 1 year after treatment. Ten to 20 percent will have a sustained response lasting at least 3 years. Ideas for improving treatment response include longer initial treatment regimens, increasing dosages of interferon alpha, or adding another agent to interferon alpha. Based on encouraging study results, the interferon/ribavirin combination has been approved by the Food and Drug Administration (FDA) in HCV patients relapsing following interferon alpha monotherapy. So far the FDA has approved interferon alfa-2b, interferon alfa-2a, alfacon-1, and interferon alfa-2b/ribavirin as treatments for HCV; ribavirin alone is not effective against HCV infection. Other drugs are being tested with interferon alpha but have not generated enough substantive data. Thymosin, an immune modulator that enhances the body's production of interferon and interleukin rather than attacking HCV directly, is also being investigated. Oral dosing of interferon is in clinical trials for hepatitis B, and the results may be applicable to HCV. Alternative therapies are gaining wider interest such as using milk thistle for liver regeneration or using licorice root for quelling liver inflammation. As for transmission risk, there is little evidence supporting sexual activity as a major risk factor, however, some risk is reported with anal intercourse, sex during the menstrual cycles, and years of cohabitation with an infected partner.
