Prostate Cancer and Nutritional Supplements
Years of research have discovered that the foods a man chooses to eat (or doesn’t eat) can have a profound impact on the health of his prostate gland. Because of this close nutritional link, prostate cancer may be the most preventable type of cancer (after smoking-related lung cancers).
Recently, there has been an incredible amount of research and investigation of prostate cancer. Many of these studies have explored the use of certain nutrients to prevent and actually treat prostate cancer. These nutrients, calcium D-glucarate selenium, broccoli, green tea, maitake, and lycopene are powerful prostate cancer fighters. All are available as nutritional supplements that men can take every day as an important part of a healthy diet.
In this issue of Ask the Doctor, we will discuss prostate cancer and how men can actually prevent it with the use of these six nutrients. Plus, if men already have prostate cancer, these nutrients can be an important part of their treatment regimen in fighting their disease.
Q. What does the prostate gland do?
A. The prostate is a gland in a man’s reproductive system. It makes and stores seminal fluid, the milky fluid that nourishes sperm. This fluid is released to form part of the semen. The prostate is about the size of a walnut and it is located below the bladder and in front of the rectum. The prostate actually wraps around the upper part of the urethra, the tube that empties urine from the bladder through the penis.
Q. What are the symptoms of prostate cancer?
A. Early prostate cancer often does not cause any symptoms. However, many symptoms of prostate cancer are also symptoms of other problems with the prostate, such as an infection or benign prostatic hyperplasia, a prostate enlargement associated with age-related changes.
A man who has any of these symptoms should see his health care practitioner for evaluation:
-A need to urinate frequently, especially at night
-Difficulty starting urination or holding back urine
-Inability to urinate
-Weak or interrupted flow of urine
-Painful or burning urination
-Difficulty in having an erection
-Blood in urine or semen
-Frequent pain or stiffness in the lower back, hips, or upper thighs.
Q. Are certain men more prone to get prostate cancer?
A. Age is the biggest risk factor: most prostate cancers occur in men over 65 years of age. A man’s risk for developing prostate cancer is higher if his father or brother has had the disease. African-Americans are at higher risk for the disease. Mechanics, farmers, sheet metal workers, and workers exposed to cadmium have also had high rates of prostate cancer.
Q. How is prostate cancer diagnosed?
A. A man who has any of these risk factors may want to ask his health care professional whether to begin screening for prostate cancer (even though he does not have any symptoms), what tests to have, and how often to have them.
The usual prostate tests include: Digital rectal exam: the doctor inserts a lubricated, gloved finger into the rectum and feels the prostate through the rectal wall to check for hard or lumpy areas.
Blood test for prostate-specific antigen (PSA): a lab measures the levels of PSA in a blood sample. The level of PSA may rise in men who have prostate cancer, benign prostatic hyperplasia (a non-cancerous enlargement of the prostate gland), or an infection in the prostate.
These tests will only determine if there is a problem with a man’s prostate gland. They cannot determine if the problem is cancer. Only a biopsy of a sample of prostate tissue can reveal the presence of actual prostate cancer.
Q. What nutrients help prevent or treat prostate cancer?
A. The prostate health nutrients, calcium D-glucarate, selenium, broccoli, green tea, maitake, and lycopene, each work in unique ways. Some help men’s bodies’ work more effectively some keep cancer cells from growing, while others actually kill prostate cancer cells. Let’s discuss each nutrient and how it works.
It is a troubling fact of modern life that we are continuously exposed to cancer-causing chemicals and toxins. These toxins come in part from contaminants in the food we eat and pollutants in the air we breathe. There are also “natural” toxins that are produced in our bodies. Excess hormones, such as estrogen and testosterone, can cause cancer when they are no longer needed. Cancer causing chemicals not only initiate cancer, but exposure to them can also cause existing cancers to grow bigger, stronger, and more deadly.
Our bodies do a fairly good job of eliminating some of these toxins before they can cause us harm. In the liver, the toxin is bound or attached to a chemical called glucuronic acid. The bound toxin is then excreted in bile and eventually eliminated as a waste product in the stool. However, yet another chemical, an enzyme called glucoronidase, can break this bond between the toxin and glucuronic acid. When this happens, the hormone or toxin is released back into our bodies, capable of causing us harm once more. The longer the toxins and excess hormones are in our bodies, the greater the chances they can make us seriously sick. Scientists have discovered that increased glucuronidase activity in the body is strongly associated with prostate cancer.
Fortunately, scientists have also discovered that a natural substance found in foods, calcium D-glucarate, can greatly reduce the activity of glucuronidase. Calcium D-glucarate helps our bodies keep the harmful toxins and chemicals bound to glucuronic acid. While CDG is found in fruits and vegetables, the amounts may not be sufficient to maintain effective levels to stop beta-glucuronidase. CDG has been shown in many experimental studies to significantly stop prostate cancer growth. Studies have shown that by taking calcium D-glucarate, our bodies and get rid of the toxic chemicals and excess hormones that might stimulate cancer formation.
Selenium is an essential trace mineral fund in the soil. Both plant foods like oatmeal and meats that we eat, such as chicken and beef, contain selenium. How much selenium, however, is difficult to determine. This is because the amount of selenium in soil, which varies by region, determines the amount of selenium in the plant foods that are grown in that soil. Animals, too, will have varying levels of selenium in their muscle, depending on the amount of selenium in their feed. The actual selenium level in the grasses and grains that make up animal feed reflect the amount of the selenium in the soil where they grew.
A major antioxidant, selenium slows down aging, keeps our skin supple, and helps prevent dandruff. Selenium also keeps our blood vessels healthy and protects us from heart disease. However, some of selenium’s most powerful effects are on the prostate gland.
In a recent study, researchers recruited 974 men to take part in a large clinical trial to determine if selenium could prevent cancer. Half of the men were given selenium supplements and half were given a placebo. Researchers, who did know which group got the placebo, watched and recorded the men’s progress. The researchers were amazed to learn that selenium cut the rate of prostate cancer by 63%!
The results of this study were so impressive that it has led to many other studies of selenium and prostate cancer. In fact, researchers at the
Scientists have observed over for a long period of time, that men who eat lots of broccoli have a lower risk of getting prostate cancer. It seems that sulforaphane, a compound abundant in broccoli, is the secret ingredient responsible for this connection. Sulforaphane increases certain enzymes in the body, called phase 2 enzymes, which deactivate cancer-causing chemicals. In lab experiments, prostate cancer cells that were exposed to sulforaphane, the compound inhibited the growth of the cancer cells up to 80 percent.
There is a potent plant substance in green tea that is a very effective killer of prostate cancer cells. A recent study tested four common components of green tea and determined that one of these compounds, epigallocatechin gallate or EGCG, has a special affinity for prostate cancer cells. Scientists discovered that EGCG can stop the growth of prostate cancer dead in its tracks. The chemical structure of EGCG is very similar to substances in red wine and cruciferous vegetables, known cancer killers.
For many years, maitake mushrooms have been linked to good health in those who eat them. Called “dancing mushrooms” (possibly due to their wavy, rippling appearance or possibly due to the little dance of joy mushroom hunters perform when they find them in the woods), maitakes contain an important compound called D-fraction.
A recent study at
Some of the most exciting nutritional news in relation to prostate health involves lycopene. This carotenoid is found primarily in tomatoes, and men who eat lots of cooked tomatoes have very low rates of prostate cancer. Because promising preliminary reports demonstrate that lycopene can actually kill prostate cancer cells, there has been an explosion of lycopene and prostate cancer studies.
In one of these studies, 32 prostate cancer patients ate a pasta meal covered with three-fourths cup of tomato sauce every day for three weeks. Results showed their PSA levels dropped two points. Even signs of DNA damage dropped sharply. The ability of lycopene to drop these levels in just three weeks has impressed researchers and scientists worldwide.
Q. Do I have to take each nutrient separately?
A. While you can purchase each one of these nutrients and take them separately, all of these nutrients are available in prostate health formulas. Make sure the formula you buy contains calcium d-glucarate, lycopene, and selenium, broccoli standardized to contain a minimum of 125 mcg sulforaphane, green tea, and maitake mushroom extract. Standardized ingredients provide consistently effective nutrients.
Q. What else can men do to prevent prostate cancer?
A. Adopting a healthy diet, including eating 5 to 9 servings of fruits and vegetables every day, eating several servings of whole grain cereals and bread, and reducing red meat consumption to 2 or 3 servings per week has been shown to reduce the risk of all kinds of cancer. In addition, the recent lycopene studies suggest that a diet that regularly includes tomato-based foods may help protect men from prostate cancer.
Men 50 years and older should have a digital rectal exam (DRE) and PSA test each year. African-Americans and those at higher risk should begin at age 40. Talk with your health care professional to determine how frequently the test should be done.
This year doctors expect to find 180,000 new cases of prostate cancer is the
More cancers are caught early and new treatments might help make it possible for men to live long and healthy lives following their diagnosis. By taking a few simple steps, men diagnosed with prostate cancer can take charge of their lives and overcome much of the fear and anxiety that accompany a cancer diagnosis.
