There’s Good News and Bad News about Prostate Health …

Important information about saw palmetto!

Three recent studies investigating the effectiveness and effect of saw palmetto on prostate tissue came up with the same conclusion: Saw palmetto has an effect similar to chemotherapy on prostate cells—it kills both unhealthy and healthy cells!

Up until now, saw palmetto extract has been the supplement of choice in the treatment of BPH. Saw palmetto is very good at helping to shrink overgrown prostate tissues, and it was thought to reduce the level of DHT by blocking its receptor sites in the prostate and by inhibiting enzymes necessary for DHT conversion.

Unfortunately, 3 recent surprising scientific studies indicate saw palmetto may work, but also harm your prostate health!

  1. One study examined the effect of saw palmetto on stroma cells—the framework cells that build supportive tissue — and on epithelial cells —those which line the glands and ducts of the prostate. The study was done on normal prostate tissue and on BPH tissues from patients treated with and without the saw palmetto. The conclusion was that saw palmetto damages the nuclear and mitochondrial membranes, and causes cellular death in the epithelium and stroma.7 
  2. Another study investigated the effects of saw palmetto on primary cultures of fibroblasts (cells that produce connective tissue), and epithelial cells from the prostate, epididymis (the tube that provides for the storage, transmission and maturation of sperm), testes, kidney, skin and breast to determine if the action of saw palmetto is selective and specific to prostate tissue. This study concluded that saw palmetto caused damage and death in prostate tissue, but there were no similar changes observed in other types of cells.8 
  3. This study examined the effect of saw palmetto on benign prostatic hyperplasia (BPH). Again, the results showed there was widespread damage of intracellular membranes, including mitochondrial and nuclear membranes in both healthy and overgrown prostate tissue.9

Because of this new information, it seems prudent to avoid saw palmetto extract as a preventative supplement for prostate health. Saw Palmetto may eventually turn out to be an effective way to kill prostate tumor cells, but its toxicity to healthy prostate cells is reason enough to be concerned about taking saw palmetto daily as a means of preventing prostate problems.

Current studies indicate that about 12 million men in the United States alone are affected by BPH.

You don't have to be one of them. Even if you're not experiencing symptoms, it's never too early to support and tone your glandular tissues and help regulate hormonal imbalances.

Comprehensive prostate care

Fortunately, researchers and medical professionals from around the world are reporting encouraging data on "male" nutritional supplements in addition to saw palmetto—and their effectiveness in supporting prostate health. But most supplements sold in the US don't measure up to the European pharmaceutical standards and aren't nearly as effective.

Key nutrients and herbal extracts provide prostate support

The prevention of prostate cancer and BPH has been shown to be related to dietary intakes of some key nutrients, and several herbal extracts also can strongly influence prostate problems. BPH and cancer are very treatable health conditions. But a lot of formulas do not contain high quality ingredients. It's very important, however, that the particular herbal extracts and nutrients are of the highest quality available and meet European pharmaceutical standards.

We, at Smart Publications, have reviewed all the literature on nutritional prevention and treatment for BPH and prostate cancer. In this body of research, there are many natural substances that have positive effects on prostate health. However, we were not satisfied with a suggestive study or two. We looked hard and selected the following 10 items based on the following criteria:

  1. There had to be a significant number of studies indicating positive prostate health effects and the studies had to be independently replicated.
  2. We had to be convinced about the safety based on a long history of traditional use of the substance by humans or long history of scientific investigation or both.

Here's what we found:

  1. Boron - According to a study done last year at UCLA, men with the highest boron intake were 65 percent less likely to develop prostate cancer than men with the lower boron intake. The researchers compared dietary patterns of 76 men with prostate cancer to that of 7,651 males without cancer. Men in the lowest quartile of boron consumption ate about one slice of fruit per day, while those in the highest quartile ate 3.5 servings of fruit per day. The researchers found that boron's cancer-fighting effects seem to be specific for prostate cancer. Foods that are high in boron include: red wine, raisins, peanuts, apples, pears, peaches, oranges, grapes, lima beans, and peanut butter.10 
  2. Daidzein - is an isoflavone found in soybeans, legumes and peas. Soy isoflavones are free radical scavengers (potent antioxidants) and are antiangiogenic (interfere with unwanted blood vessel growth in disease states). They have been shown to have a beneficial effect on various types of cancer.

    In countries like Japan, where soy consumption is high, there is approximately an 80 percent lower incidence of prostate cancer than in the West. In a study that followed Japanese men who immigrated to the United States and abandoned their traditional diets, it was found that within one generation, there was a four-fold to nine-fold increase of prostate cancer among them.11 But, unfortunately, the main isoflavone in soy, genistein, actually seems to have undesirable toxic effects. Only now is pure daidzein, the other isoflavone in soy, available as a supplement.

    Daidzein doesn't share genistein's toxic properties, and was demonstrated to be very protective against prostate cancer in a study showing that peas dramatically reduce risk of prostate cancer. Peas contain a lot of daidzein, but not genistein.12 
  3. Grape seed extract - contains proanthocyanidins, potent antioxidants that may lower the risk of cancer. In a recent study, grape seed extract was used to inhibit cell growth in human cancerous prostate cells. The results suggest that grape seed antioxidant proanthocyanidins may exert a strong anticarcinogenic effect against prostate cancer by inhibiting abnormal cell growth and promoting tumor cell death.13 
  4. Green tea - Next time you eat at a Japanese or Chinese restaurant, order a pot of green tea! It not only tastes good, but scientists have observed that people who consume tea regularly have a lower risk of prostate (and breast) cancer-related deaths. In fact, the incidence of prostate cancer in China, a population that consumes green tea on a regular basis, is lowest in the world.14 And sure enough, recent studies done both on human cells and mice, have shown that green tea's polyphenol—epigallocatechin-3-gallate—blocks the growth of prostate cancers.151617 
  5. Lycopene - Have you had your tomato sauce today? This member of the family of phytochemicals known as carotenoids, is a powerful antioxidant that is found in red fruits and vegetables, especially tomatoes, watermelon, red grapefruit, and guava. Researchers have linked the frequent use of lycopene from tomatoes to a lower risk of prostate and other cancers.18 Interestingly, in one study, researchers found that significantly lower serum and tissue lycopene levels were observed in the cancer patients than in their control group, indicating that lycopene prevents oxidative damage of biomolecules and consequently reduces the risk of prostate cancer.19 
  6. Vitamin E - is a major antioxidant nutrient that helps maintain healthy membranes and retards cellular aging due to oxidation. It is especially important to sexual and reproductive health. One study that followed more than 29,000 male Finnish smokers, ages 50 to 69, for five to eight years, showed that vitamin E reduces the risk of prostate cancer.20 

    Our diets contain mostly the gamma tocopherol form of vitamin E. Most dietary supplements contain only alpha tocopherol, not gamma tocopherol. Unfortunately, high intakes of alpha tocopherol actually pushes the preferred gamma form of vitamin E out of the body. And since the most current research shows it is gamma tocopherol that is associated with a reduction of prostate cancer—especially when combined with selenium and alpha tocopherol 21 —make sure you take a supplement that contains gamma and alpha, not just alpha tocopherol!21 
  7. Selenium - There have been many studies showing a direct connection between selenium and prostate cancer, and most nutritionist agree, it's hard to get enough of it on a daily basis without taking a nutritional supplement. In the now famous Clark Study, a 63% reduction in prostate cancer was found in men who received 200 micrograms of selenium from a selenium-enriched yeast containing mostly selenomethionine. The conclusion? Eat more tuna, Brazil nuts, and sunflower seeds, and to guard against gaps in your diet, take a daily supplement containing 200 micrograms of selenium from selenium-enriched yeast or selenomethionine!22 

    Another study conducted at Stanford University found that low plasma selenium is associated with a 4 to 5-fold increased risk of prostate cancer. These results support the hypothesis that supplemental selenium may reduce the risk of prostate cancer. And because plasma selenium decreases with patient age, supplementation is particularly beneficial to older men.23 
  8. Kohki leaf- If you have problems with an overactive bladder—a common and annoying BPH complaint—this nutrient will help cut down your trips to the bathroom! Unlike other compounds, Kohki actually prevents the adverse changes in the bladder that often accompany prostate problems. Kohki comes from a subtropical plant that grows wild in southern China. It has been used medicinally in East Asia for hundreds of years and is sold over the counter today in Japan as a medicinal tea. It contains strong antioxidants, including several dihydroflavonol glycosides, that have been shown to have a significant protective effect on bladder function.24 
  9. Pygeum africanum - is an evergreen tree that grows in the mountainous forests of Africa. Unfortunately it has become an endangered species due to its popularity as a european pharmaceutical for prostate problems. Luckily, high quality extract is still being produced using farmed trees grown on plantations for medicinal use. This bark extract has been prescribed by European doctors for years, both to help preserve prostate health and promote a man's overall well being. Pygeum not only helps common prostate problems but also promotes prostate function. Unlike saw palmetto, it is not toxic to prostate cells and is even an antioxidant. It contains a variety of active compounds that synergistically aid prostate health. Many studies have shown the effectiveness of Pygeum extract in treating BPH, including reduction of the frequency of nighttime urination25; and relief of symptoms associated with genito-urinary problems resulting from BPH.26 
  10. Nettle root - commonly known as stinging nettles, you may have had the experience of walking through a field of this plant in Great Britain. Unpleasant, yes! But if you want to prevent or relieve reduced urinary bladder capacity, urinary outflow, and residual urine flow, the extract made from the root of this medicinal plant will help do the trick. It is well documented and recognized, especially in Europe, to relieve symptoms of BPH2728. Just make sure you're using nettle root and not nettle leaf, which is used to alleviate arthritis symptoms, not prostate problems.

IMPORTANT NOTE about European Medicinal Herbs like Saw Palmetto, Pygeum, and Nettle:
While these 3 herbal extracts are successfully used in European countries for prostate problems as pharmaceuticals, and much of the impressive research has utilized these pharmaceutical grade extracts, MOST of the herbs sold in the United States DO NOT meet these exacting standards. To be sure you get outstanding results ONLY purchase products that use European Pharmaceutical Grade extracts of these three medicinal herbs.

Frequently asked questions

What's a PSA test?

PSA stands for prostate-specific antigen, a protein made by the prostate gland. It's a simple blood sample that measures the level of the protein. In general, a PSA under 4 ng/ml (nanograms per milliliter) is considered low, 4 to 10 is moderately elevated, and over 10 is considered high. Keep in mind, though, that prostate cancer isn't the only thing or even the most likely thing that can cause PSA levels to rise. An enlarged prostate can also boost scores. It's important to have a digital rectal exam along with the PSA.

What's a digital rectal exam like?

According to Tom Sansone, M.D., urologist at Bryn Mawr Hospital, says, "For a really vigorous exam, go to a urologist, Family practitioners tend to be more gentle and superficial." An urologist will manipulate the gland for a full minute, exerting pressure in order to feel for nodules, areas of hardness, changes of consistency and symmetry. A normal prostate should have two symmetrical lobes and the consistency of a rubber ball. If it's so hard that the doctor can't indent it with his thumb, then he knows there's a problem.

Can I still have sex with an enlarged prostate?

Yes, in fact, the more sex the better! Regular sex, or at least ejaculation, is beneficial since it gets the juices flowing and clears out the ducts.

If I have an enlarged prostate, will I develop prostate cancer?

Not necessarily. According to Ronald L. Hoffman, M.D., Medical Director of the Hoffman Center in NYC and host of "Health Talk", a syndicated radio program, "It is very common to have prostate enlargement without cancer. In fact, prostate enlargement is virtually universal among North American men, while prostate cancer is not. Nevertheless, it's estimated that the vast majority of men may have 'microfoci' of cancer: tiny clusters of cancer cells that are normally of very little consequence, because they are slow growing. But some of them can develop down the line." (Conscious Choice, June 1999)
