In the meantime, a recent item in a major medical journal provides an important reminder of just how important it is to let some sunshine into your day - especially if you live way up north. But even if you don't live in the extreme northern latitudes, there's one vitamin supplement that's essential during the darker winter months. ----------------------------- Alaskans and Englishmen ----------------------------- As I've told you in several e-Alerts (most recently in " SPF 2 " 10/8/03), the sun is not an enemy to our health. On the contrary, sunlight exposure is essential to good health. The key is balance. Too much sun is just as unhealthy as too little. This concept is generally not embraced by the mainstream medical establishment, so it was refreshing to find confirmation of the health properties of sun exposure in a letter published in a recent issue of the British Medical Journal (BMJ). The author of the letter is Professor Cedric F. Garland of the University of California. And his opinions about sun exposure come from his participation in more than two decades of research on this subject. Prof. Garland's letter is in response to an earlier editorial in BMJ in which the authors advised avoiding sun exposure to reduce the incidence of cancer. But Prof. Garland says that a recommendation of moderate exposure to the sun would be more prudent. He explains that " Solar exposure is the main source of vitamin D, " and goes on to cite specific studies that demonstrate how vitamin D has been shown to reduce the risk of several cancers, including colon, breast, and prostate. He adds that the body can only store vitamin D for a few weeks, so those who live in northern latitudes would be helped by vitamin D supplements. And you don't have to be a polar explorer to find yourself vitamin D deficient. Prof. Garland says that people living in the UK are unable to synthesize vitamin D from November to March. But the UK is pretty far north; parts of Scotland are on the same latitude as Alaska. So what about those of us who live further south, but not so far south that palm trees grow outside our windows? ----------------------------- From Phoenix to Boston ----------------------------- In a study that appeared in the journal Cancer last year, the lead author, Dr. William B. Grant, set out to determine an association between premature deaths from cancer and insufficient ultraviolet (UV-B) radiation. Comparing UV-B data with cancer mortality rates in the U.S. between 1970 and 1994, Dr. Grant found a clear correlation between low UV-B radiation exposure and mortality due to 13 different types of cancer. These cancers include the cancers mentioned in Prof. Garland's research, as well as pancreatic, stomach, kidney, lung, and other cancers. More specifically, Dr. Grant found that the rates of these cancers are almost twice as high among those who live in northeastern states compared to residents of the southwest. He concludes that many lives could be saved by " increased careful exposure to solar UV-B radiation. " He also recommends supplementation with vitamin D3 (vitamin D from fish liver oils), especially in late autumn and winter. ----------------------------- The Wright way ----------------------------- In the February 2002 issue of Nutrition and Healing newsletter, Dr. Jonathan Wright makes clear the profound importance of vitamin D: " Although the final proof isn't in (and probably won't be in our lifetimes), it's very likely that if you're over 40 and supplement your diet with a generous amount of vitamin D, you can lower your risk of prostate, breast, and bowel cancer along with your risk of 'essential' hypertension, osteoporosis, and tuberculosis. Young adults can lower their risk of multiple sclerosis as well. " Dr. Wright recommends a daily vitamin D intake between 1600 and 2000 IUs - and as much as 4000 IUs for those over 40. According to Dr. Wright, it's impossible for most people to get enough vitamin D from the sun alone, and he discourages the use of dairy products because of the many other health concerns they raise. Instead, he suggests other food sources like salmon and sardines, or even good old-fashioned cod liver oil, which provides more than 1300 IUs of vitamin D per tablespoon. ************************************************************** To start receiving your own copy of the HSI e-Alert, visit: http://www.hsibaltimore.com/ealert/freecopy.html Or forward this e-mail to a friend so they can sign-up to receive their own copy of the HSI e-Alert. ************************************************************** ... and another thing We may have finally found a drug company representative we can trust. Earlier this month, a BBC News report quoted Allen Roses (a senior executive of Europe's largest drug maker, GlaxoSmithKline) as saying that more than 90 percent of all drugs are effective for only 30 to 50 percent of those who use them. I had to read that twice to make sure my eyes weren't deceiving me. That comment is something you might expect to hear from a dedicated herbalist or some other alternative healthcare practitioner. But you don't expect to hear it from a high-placed honcho for an international drug giant. Why would Mr. Roses utter such a statement? Apparently because he's a genetics expert with an eye toward the future of pharmaceuticals in which drugs will be tailored for specific genetic types. It seems, however, that other executives at GSK may not have been delighted by the press coverage of Mr. Roses' comment. The following day, the UK's Daily Mail reported that GSK was " on the warpath " over the way the comment had been portrayed as a " gaffe. " A GSK spokesman told the Daily Mail that Mr. Roses' statement had been misrepresented. The unnamed spokesman said that anyone working in healthcare knows that " most people respond differently to medicines. " And, " Although medicines may not work in all patients, they do work in a very large proportion. " So the spokesman basically rephrased Mr. Roses' comment to make it more ambiguous, without actually refuting the truth of it. That's what you call closing the barn door after the cows are out. But we already knew the truth about those " cows.
