DAIRY PRODUCTS AND PROSTATE CANCER

Dear Friends: This week I want to share some insightful and scientific information on the connection between prostate cancer and the intake of dairy products from the Physicians Committee for Responsible Medicine website (pcrm.org).
"Prostate cancer is the fourth most common malignancy among men worldwide, with an estimated 400,000 new cases diagnosed annually, accounting for 3.9 percent of all new cancer cases. 1 Epidemiologic evidence strongly suggests that dietary factors play a major role in prostate cancer progression and mortality, with protective effects associated with consumption of fruit (particularly tomatoes), vitamin E, and selenium, and increased risk linked to dairy products, meat, and fat. Dairy product consumption has been associated with prostate cancer risk in divergent populations, and several studies have investigated mechanisms that may explain these findings. This review describes studies reporting prostate cancer risk in relation to milk or dairy products generally. It does not include studies reporting only intake of individual milk derivatives, such as butter, or nutrients, such as fat. "Prostate cancer is one of the most common malignancies worldwide, with an estimated 400,000 new cases diagnosed annually. Its incidence and mortality have been associated with milk or dairy product consumption in international and interregional correlational studies. As a result, case-control and cohort studies have further investigated this association and are described in this review. Of 12 case-control studies, six found significant associations, as did five of 11 cohort studies, with relative risk of prostate cancer among those with the most frequent dairy product consumption ranging between 1.3 and 2.5, with evidence of a dose-response relationship. Mechanisms that may explain this association include the deleterious effect of high-calcium foods on vitamin D balance, the tendency of frequent dairy intake to increase serum insulin-like growth factor I (IGF-I) concentrations, and the effect of dairy products on testosterone concentration or activity.Two studies in northern Italy compared prostate cancer patients with hospital controls, finding increased risk of prostate cancer among those with the most frequent milk consumption. Similarly, a study at Roswell Park Memorial Institute in Buffalo, N.Y., found an increased risk of prostate cancer with the daily consumption of three or more glasses of whole milk, compared with never drinking milk. In Montevideo, Uruguay, a comparison of prostate cancer patients with hospital controls, most of whom had other forms of cancer, found an increased risk of prostate cancer associated with drinking two or more milk servings per day, compared with having less than one serving per day. In �rebro county, Sweden, men with prostate cancer were compared with controls selected from a population register. Higher dairy product consumption was associated with increased relative risk of prostate cancer. Dairy products may influence the incidence or progression of prostate cancer by several possible mechanisms. One for which evidence is particularly compelling is the effect of high-calcium foods on vitamin D metabolism. In several prospective studies, calcium intake has emerged as an independent predictor of prostate cancer risk. "Dairy product consumption has also been shown to increase serum concentrations of insulin-like growth factor (IGF-I). Case-control studies in diverse populations have shown a strong and consistent association between serum IGF-I concentrations and prostate cancer risk. In men and women aged 55 to 85 years, the addition of three daily eight-ounce servings of nonfat or 1 percent milk for 12 weeks was associated with a 10 percent increase in serum IGF-I concentration (P<0.001). Mean serum IGF-I concentration among vegans was shown to be 8 percent lower than among ovolacto-vegetarians and 9 percent lower than among meat-eaters
"Changing dietary protein sources from animal sources to plant sources has been shown to reduce serum IGF-I concentrations.
Most dairy products contain substantial amounts of fat and are devoid of fiber, a combination that is likely to increase serum testosterone concentration and activity.
"Dietary factors other than dairy products are also associated with risk. Generally speaking, diets high in animal products are associated with higher risk, while those rich in plant foods, particularly tomatoes, are associated with reduced risk. Daily soymilk consumption was associated with a significant reduction in prostate cancer risk in a cohort of 13,855 Seventh-Day Adventist men.
"Isoflavones in soymilk inhibit growth of human prostate cancer cells and also inhibit 5a-reductase, an enzyme that converts testosterone to 5a-dihydrotestosterone in the prostate.42 A similar beneficial effect was demonstrated for tofu consumption. Based on experience with a case-control study in Athens, Greece, researchers calculated that the combined effect of reducing dairy consumption, substituting olive oil for other added fats, and increasing tomato intake to the levels consumed by those in the lowest risk categories could reduce prostate cancer risk in their population by 41 percent.
"Evidence from international, case-control, and cohort studies suggests that men who avoid dairy products are at lower risk for prostate cancer incidence and mortality.
"Men who choose to avoid dairy products reap other nutritional benefits, such as a reduction in total fat, saturated fat, and cholesterol intake."

Cheese and Testicular Cancer
"In October of 2003, the largest study on diet and testicular cancer ever conducted was published, studying the diets of hundreds of cancer victims. After cheese consumption, the second strongest dietary risk factor for testicular cancer seemed to be the consumption of lunch meat." International Journal of Cancer 106 (2003): p. 934.
I believe the evidence proves that dairy consumption can contribute to an increase in prostate cancer.
Stay healthy,

CELIAC DISEASE
A Hidden Epidemic |
In 1994 I learned that I had Celiac Disease or Gluten Intolerance. The disease, once known as Malabsorption Syndrome, is an autoimmune disorder that affects nearly one in every hundred people in the United States, of which 97 percent remain undiagnosed and untreated. Celiac Disease is spreading and expanding and the average reader probably has difficulty keeping up with new developments. My purpose in writing this article is to hopefully help someone who might be suffering from an autoimmune disease that may actually be linked to Celiac Disease.
Some of the known symptoms of CD are gastrointestinal problems, joint pain, headache, anemia, constipation and/or diarrhea, fatigue, depression, and skin conditions, but research is finding that the disease is a multisystem disorder and can cause other serious complications such as infertility, type-1 diabetes, thyroid disease, alopecia areata, peripheral neuropathy, rheumatoid arthritis, liver disease, and even cancer. The true medical impact of celiac disease is just beginning to emerge. In the book Celiac Disease - A Hidden Epidemic, by Peter H. R. Green, M.D., Director of the Celiac Disease Center at Columbia University, and Rory Jones reported: "In the United States today, millions of patients suffer with symptoms that neither fit a specific diagnosis nor disappear. Young and old take drugs and see numerous specialists for gastrointestinal complaints, anemia, joint pain, itchy skin conditions, constant fatigue, or headaches and migraines. Their symptoms are treated, but no underlying cause can be found. One doctor diagnosed fibromyalgia, another chronic fatigue syndrome, a third irritable bowel syndrome. ... Celiac disease is a multisystem disorder whose primary target of injury is the small intestine. The disease is triggered by gluten, the main storage protein found causing food malabsorption continues and the disease progresses, the manifestation inevitably become more varied and complex. Celiac disease is the most common and one of the most underdiagnosed hereditary conditions in the United States today. ... Only recently have studies shown that celiac disease affects approximately 1 in every 100 people, and 97 percent of them are undiagnosed." Celiac Disease, p. 3. Dr. Green continues: "Frequently, the associated autoimmune disease is diagnosed first because it is more obviously symptomatic, while the celiac disease remains silent. Nevertheless, it is believed that celiac disease may come first, predisposing individuals to the development of the autoimmune diseases. Unfortunately, autoimmune disorders are often so well established by the time of diagnosis for celiac disease--with evidence of organ damage, not just the presence of antibodies, that a reversal of the condition is very unlikely." Ibid, p.155. Celiac disease is an abnormal reaction to a normal food substance. I have learned that one man's food, especially glutinous foods like wheat, rye, barley, kamut, spelt and triticale, may be another man's poison. The body treats gluten, the storage protein in these foods as a foreign body that inflames the villi of the small intestine in order to protect the body from the invaders. The villi flatten and the condition causes malabsorption of nutrients which can predispose the body to an autoimmune disease. A large percentage of celiacs are deficient in folic acid and should take a B-Complex supplement. I was deficient in B-12 and noticed improvement once I started injections. Vitamin B-12 deficiency can manifest symptoms which are similar to MS. The gold standard for diagnosing CD is an internal biopsy, but a blood test, IgA Endomysial Antibodies (EMA), is highly specific, virtually 100% percent so, and about 90 percent sensitive. Dr. Green also gives a health questionnaire in his book that may indicate that you should take the IgA blood test. Here is the list of symptoms: � Bloating, gas, and/or stomach cramping � Diarrhea or runny stools � Constipation � Joint pain, fibromyalgia, or numbness or tingling in your extremities � Itchy skin lesions, eczema, or unexplained dermatitis � Constant unexplained fatigue or chronic fatigue syndrome � Frequent headaches or migraines � Lactose intolerance � Osteopenia and or/ osteoporosis � Autoimmune disorders (thyroid disease [hypo/hyper], type 1 diabetes, Sjoren's syndrome, chronic liver disease), or an immediate family member with an autoimmune disease � Peripheral neuropathy � Non-Hodgkin's lymphoma � Small intestinal cancer � Psychiatric disorders or depression � Anemia (iron deficiency) � Infertility I experienced multiple symptoms whenever I ate gluten, and therefore must avoid it completely. Some of the symptoms which could change from episode to another were gas, diarrhea, constipation, bowel pain and bloating, depression, suicidal, extreme mood swings, irregular heart rhythms, and muscle twitching. I was also diagnosed with Multiple Sclerosis, but the symptoms disappeared when I stopped eating all gluten. In fact, I experience none of the symptoms as long as I follow a gluten-free diet. When I first was diagnosed with CD, I suffered from depression, diarrhea, and weight loss. Today if I eat gluten, I get hangover-like symptoms, abdominal pain, irregular heartbeats, muscle twitching, and a foggy brain. I also can have a delayed allergic reaction and symptoms on Wednesday if I eat gluten on Monday. Many people fail to realize the possibility of a delayed allergic reaction and, therefore, think the food they ate on the given day caused the reaction. Here is a letter from Kathy who suffered from rheumatic arthritis and psoriasis since childhood. Not one doctor had ever suggested or tested her for CD, which she finally learned was the cause of her life-long problems. Dear Danny: One year ago, I came for a consultation because I had questions concerning my arthritis. Along with your recommendations of a vegan, whole foods diet, you also encouraged me to investigate celiac disease. After six months of dietary experimentation, I saw a gastroenterologist and received a diagnosis of celiac sprue. My only symptoms were arthritis (diagnosed at age 11) and psoriasis (diagnosed at age 3). I am also noticing an improvement in my overall health, both mental and physical after abstaining from gluten. I was on Methotrexate and NSAIDS for 14 years, and for the last five years have taken Prednisone (the only "safe" drug for the childbearing years). I now have been off Prednisone and all medications, (the first time in 20 years) for one year and I FEEL WONDERFUL! My goal in writing is to THANK YOU for your determination to provide quality health information. You have, by God's wonderful grace, influenced me, my whole family, many of my friends, and even my neighbors, towards better health. I especially appreciated the personal trainer you had on your radio show Healthline. I was a fitness professional and educator before having the privilege of becoming a fulltime mom. I can smell an un-educated trainer from a mile away. The gentleman you interviewed, Bobby Spencer, was well educated and has a true understanding of fitness and how the body works. Thank You! I am praying that one day you will do a show on Celiac Sprue. My Gastroenterologist and the celiac websites say it is highly under-diagnosed. When I mentioned being tested for gluten intolerance as a possible cause for Psoriatic Arthritis, people thought I was crazy (even my primary-care physician). A Gastroenterologist at UC Davis told us of a recent study in Italy where the group of people's only symptom was that they were short, and when put on a gluten-free diet they grew, and they were all past the growth stage in life. He also said they are making connections between Celiac and Alzheimer's disease. I know that many would benefit from a show on Celiac disease; the symptoms are so varied and numerous, and the diagnosis is as easy as a blood test. With kind regards, Kathy G. The late Dr. Lloyd Rosenvold, M.D., the physician who diagnosed me with gluten intolerance, or Celiac Disease, reported: "In the Scandinavian Journal of Rheumatology 21:20-23 (1992), a study is reported where our of 70 patients with various rheumatic complaints 23 persons were found by intestinal biopsy to have Celiac Disease. That is about 1/3 of all cases of rheumatic disease. Surely every case of any rheumatic problem or arthritis should be tested for CD." Rosenvold continued: "I recently learned of a case of rheumatism so severe that he was forced to discontinue his work. A gluten-knowledgeable friend dined with him one day and noted that he partook of enormous amounts of gluten foods. It has been shown in past observations that the gluten meat analogs consumed but many vegetarians tend to precipitate overt CD in cases of latent or previously unknown CD. Actually the gluten-based analogs are not really 'health foods.'" Dr. Rosenvold also reported: "We have records of patients who have suffered from heart beat irregularities caused by intolerance to gluten in the diet. Four of these suffered from extrasystole beats (skipped heart beats). When they discontinued gluten, the irregularities disappeared." I have noticed irregular heartbeats if I eat gluten. The late Ear, Nose and Throat specialist also said that gluten intolerance can cause auricular fibrillation and chronic fatigue syndrome. A study in Finland reported that in ten patients with CFS, seven of them obtained full relief as soon as they went on a gluten-free diet. Do you have friends that are chronically tired for no obvious reason? Try suggesting a gluten-free diet for a month or two. I remember watching a health series by Dr. Gary Null on PBS, years ago, and he advised everyone feeling tired and fatigued to get off all wheat products. I would go further than this -- I would suggest they get off all gluten products. I know of many people who were suffering with many symptoms but never suspected celiac disease as the root cause. Dr. Rosenvold treated me not only for CD, but a secondary condition called candida albicans which has a whole list of symptoms much like CD. He said, "When the villi lay flat in the small intestine, candida fungus has a greater opportunity to proliferate in the jejunum." If you have any of the diseases mentioned in this article and are at your wit's end in trying to figure out what is wrong with you, please consider a gluten-free diet for a month or two for it may make all the difference.
