Guest guest Posted December 7, 2004 Report Share Posted December 7, 2004 (I have frequently mentioned selenium here and it's importance for your thyroid treatment--selenium improves the conversion of T4, to T3. Below is the latest info to come out about selenium--it's a great supplement to take! And note the following from below: " North and South Dakota, Utah, Colorado, Montana and Wyoming: Anyone who lives in these states and eats ample amounts of locally grown fruits and vegetables daily is probably getting a good selenium intake. But the rest of us are probably not, unless we're taking a selenium supplement or a multivitamin that contains selenium. " Janie) Don't underestimate the dirt beneath your feet. Especially if you're standing on farmland soil in the western U.S. Soil contains a trace mineral called selenium. When you consume food that's grown in selenium-rich soil, your body is replenished with a nutrient that has been shown to help fight autoimmune disorders, increase insulin efficiency, and curb the mutation of viruses. And if this were a late night infomercial, right about now I would say, " But wait! That's not all you get! " Because selenium also has excellent antioxidant qualities, it boosts the antioxidant power of vitamin E, and it's been shown to reduce the risk of several types of cancers by triggering the activity of a tumor-suppressing gene. And that's where today's e-Alert begins: Out west, with an Arizona study that evaluates the association of selenium intake with the reduced risk of one of the most common types of cancer. Researchers at the University of Arizona (UA) wanted to expand on previous research, which had indicated that selenium may reduce the risk of developing colorectal tumors. The UA team used data combined from three trials: the Wheat Bran Fiber Trial, the Polyp Prevention Trial, and the Polyp Prevention Study. Each of these projects examined the effects of different nutritional factors on the prevention of benign colorectal tumors in patients who previously had such tumors removed during colonoscopy. Medical records and blood tests of more than 1,700 subjects were analyzed to determine tumor developments and selenium concentrations. When the subjects were grouped ranging from least blood concentration of selenium to greatest, results showed that subjects with the highest blood selenium values had " statistically significantly lower odds " of developing a new tumor when compared to subjects with the lowest blood selenium values. The researchers also noted that each of the three trials individually indicated selenium's protective effect against the recurrence of tumors, and that those with the very highest blood selenium value had more than a 40 percent reduced risk of tumor recurrence compared to subjects with the very lowest levels of selenium. ------------------------------------------------------------ The big six ------------------------------------------------------------ In the UA study - which appears in a November issue of the Journal of the National Cancer Institute - the researchers note that, given the limitations of the data from the three trials, they were not able to pinpoint the selenium sources in the subjects' blood samples. Therefore they couldn't draw any conclusions about supplementing with selenium. As I've noted in previous e-Alerts, in the U.S., selenium is highly concentrated in the soil of only six states: North and South Dakota, Utah, Colorado, Montana and Wyoming. Anyone who lives in these states and eats ample amounts of locally grown fruits and vegetables daily is probably getting a good selenium intake. But the rest of us are probably not, unless we're taking a selenium supplement or a multivitamin that contains selenium. The U.S. RDA for selenium is 55 mcg for women and 70 mcg for men, but the average diet falls far short of that amount - especially if you don't eat produce from one of the six states mentioned above. Research into the cancer- preventive qualities of selenium indicates that a daily intake needs to be around 200 mcg to insure adequate prevention. Which brings up the issue of selenium toxicity. Selenium comes with a general warning about high intake of this nutrient. And while it's true that mega-dosing might create problems, you would have to get more than 2,500 mcg of selenium per day for an extended period to receive a toxic amount, so the actual chances of getting a dangerous dose are extremely slim. In addition to fruits and vegetables, bread, fish and meat all contain selenium. The real selenium powerhouse, however, is the Brazil nut, delivering more than 800 mcg of selenium per ounce.

Guest guest Posted December 7, 2004 Report Share Posted December 7, 2004 I'm taking 200 mcg selenium capsule everytime I take my Armour. Also take it with zinc. So that's 400 mcg selenium per day. I guess that's not a toxic amount? Maybe I should only take it once a day with the morning thyroid dose?

Guest guest Posted December 7, 2004 Report Share Posted December 7, 2004 Hi Caroline. The answer is in the last paragraph of mine that you left. What you are taking is fine, but it would be fine to take it once a day, too. Janie ) > I'm taking 200 mcg selenium capsule everytime I take my Armour. Also take it with zinc.

Guest guest Posted December 7, 2004 Report Share Posted December 7, 2004 ok...that's a relief. Thanx. From: loboshe Hi Caroline. The answer is in the last paragraph of mine that you left.
