It lowers colorectal cancer risk, strengthens bones, supports heart and muscle health, stimulates digestive enzymes, and can even help make weight-loss diets more effective. But recent research suggests that very high levels of dietary calcium intake - particularly from dairy products - may increase the risk of one of the most common forms of cancer. ----------- Milky way ----------- Last month, researchers at the Fox Chase Cancer Center in Philadelphia published the results of a study that examined the association between calcium and dairy product intake and the increased risk of prostate cancer. Using data from the first National Health and Nutrition Examination Epidemiologic Follow-Up Study, nearly 10 years of medical records were collected on more than 3,600 men. All of the men had completed dietary questionnaires in the early 80s. The Fox Chase team identified 131 cases of prostate cancer. After adjusting for age, race, smoking and other factors, they produced the following conclusions: * Men who reported the highest dairy product intake were 2.2 times more likely to develop prostate cancer compared to men who had the lowest intake * Similarly, men who had the highest intake of dietary calcium were also 2.2 times more likely to develop prostate cancer * Men who reported the highest intake of low-fat milk were 1.5 times more likely to develop prostate cancer compared to men who had the lowest intake, but whole milk intake was NOT found to be linked to increased risk * Neither vitamin D nor phosphorous was linked with increased prostate cancer risk ----------- Know your risk ----------- So...what gives? Low-fat milk raises risk, but whole milk doesn't, in spite of the fact that high dairy intake does raise risk? In their conclusions, published in the American Journal of Clinical Nutrition, the researchers write: " The mechanisms by which dairy and calcium might increase prostate cancer risk should be clarified and confirmed. " I would say that's putting it mildly. I'll be keeping an eye out for further studies that examine the dairy intake/prostate cancer association. Obviously, something important seems to be going on here, but we're a long way from sorting out the specifics. In the meantime, men and their doctors should at least make note of this potential risk factor for prostate cancer. And that's especially true for men who are already in high-risk groups. Here are some of the primary risk factors as cited by the American Cancer Society: * Prostate cancer risk rises after the age of 50; men over the age of 65 account for more than 70 percent of all prostate cancer cases * Risk more than doubles in men whose father or brothers have prostate cancer * Risk is considerably higher if several relatives also have prostate cancer, or if a relative was young when diagnosed * African-American men have a higher risk than white American men and Hispanic men; Asian men have the lowest risk of the four groups * Risk is believed to be higher in men whose diets include large amounts of red meat, especially if their diets do not include adequate amounts of fruits and vegetables ----------- The old standbys ----------- As long as we're on the topic of prostate cancer risk, I'll quickly review two nutrients that may significantly reduce that risk: vitamin E and selenium. In the e-Alert " Taking Yourself Off the List " (4/22/04), I told you about a trial of 300 middle-aged men in Finland. Those who took a vitamin E supplement for more than five years reduced their prostate cancer risk by almost a third, compared to men who didn't supplement with the vitamin. And risk dropped even further for those who also ate foods rich in vitamin E (including almonds, spinach, mustard greens, green and red peppers and sunflower seeds). And in the e-Alert " Trace Mineral Key to Preventing Prostate Cancer " (12/5/01), a Stanford University study demonstrated that men with low blood levels of selenium may be four to five times more likely to develop prostate cancer than men with normal levels of the mineral. The study also confirmed that selenium levels decrease as men age - mirroring the fact that prostate risk steadily rises as men age. Besides the fact that selenium has excellent antioxidant properties that have been shown to help increase insulin efficiency, selenium also enhances the effect of vitamin E, making it a perfect match for any vitamin E regimen designed to help prevent prostate cancer. Foods that contain selenium include fruits and vegetables (if grown in selenium-rich soil), beef, tuna, turkey, chicken, eggs and whole wheat bread. Brazil nuts contain more selenium than any other food: 840 mcg of selenium per ounce. **************************************************** ....and another thing In spite of its " wonder drug " reputation, the evidence against aspirin just keeps mounting. Earlier this week, in the e-Alert " Low Dose or No Dose " (5/31/05), I told you how elderly people with no history of cardiovascular disease may sharply increase their risk of bleeding in the brain and/or the gastrointestinal tract if they take a daily low-dose of aspirin to help prevent heart attacks. But how does aspirin use affect people who already have cardiovascular problems? After a patient experiences a first heart attack or stroke triggered by thrombosis (a blood clot in the heart or a blood vessel), many doctors prescribe an anti-thrombotic regimen of aspirin or warfarin, a prescription blood thinner. As reported in the July 2004 issue of the American Heart Journal, UK researchers at the University of Hull divided 279 subjects from the Warfarin/Aspirin Study in Heart failure (WASH) into three groups: one group received 300 mg of aspirin daily, one received a standard daily dose of warfarin, and a third group received placebo. Each of the subjects had experienced either heart attack or stroke, prompted by thrombosis. After an average follow up period of more than two years, the researchers found that neither the aspirin nor the warfarin therapies provided any greater protection against death, nonfatal stroke, or nonfatal heart attacks than the placebo. In fact, subjects who received aspirin therapy were nearly twice as likely to suffer a heart attack or stroke as were those who took warfarin or placebo. Gastrointestinal problems were also elevated in the aspirin group. In an interview with Reuters Health, the lead researcher of the study, Dr. John G. F. Cleland, stated that any theoretical benefit of using aspirin after a heart attack, " is outweighed by real evidence of harm.

Guest guest Posted June 3, 2005 Report Share Posted June 3, 2005 OY, I need to read my articles better. This I must write about. I didn't really read this well enough. So... when milk products are consumed, if the body does not get enough vitamin d and magnesium, the calcium is not used right and collects (like on arthritic fingers). Cow's milk contains almost NO magnesium but high calcium so this would explain any findings that milk isn't good for you in regard to prostate cancer. Interesting that in this study whole milk was not much of a risk. I just love how America butchers it's foods for the sake of health, sorry for sarcasm, but pasteurization causes so many free radicals to form it isn't funny. ANd then they played around with milkfats, etc. Ahhh, anyway, I have reread it again and I'm sorry I sent it. It was written poorly. Take care, Glad to see people are finally writing on this great list! Kel --- " Kelly W.
