So another study is out suggesting that Vitamin D may reduce the risk of cancer. New research found that "vitamin D cut the risk of several types of cancer by 60 percent overall for older women."
The study was small and was really supposed to be more about bone health. And one Skeptical Guy said: "I don't think it's the last word." (Okay, so Skeptical Guy was a nutrition and cancer researcher at the Harvard School of Public Health. Whatever.)
But apparently there were some cool methodological aspects of the research which managed to get Other Less Skeptical Scientists pretty excited. (Crabby won't go into these here, because she doesn't want to start getting a reputation for scientific rigor or thoroughness. But go ahead and click on the link if you want to know more).
If fact, Cedric Garland got so excited he declared the findings "a breakthrough of great medical and public health importance!" Who is Cedric Garland? "A prominent vitamin D researcher at the University of California San Diego."
Crabby must pause for a moment at this juncture to note that this would be a great answer to that tiresome cocktail party inquiry: "And so what is it you do?"
"I'm a prominent Vitamin D researcher at the University of California San Diego!" Cedric might exclaim, turning down a proffered martini in favor of a big glass of milk.
(Or perhaps not. Crabby feels especially entitled to tease UCSD researchers because UCSD is her alma mater. Or one of them, anyway. And she wants to know: is there still a fountain in the plaza of Revelle College into which undergraduates are thrown on their birthdays?)
Vitamin D is the one you get from the sun, but watch out for skin cancer. It's also found in foods, like salmon, tuna and fortified milk. But apparently many people in the U.S. don't get enough from diet and sun exposure.
How about supplementation? As usual, the experts can't seem to agree on whether to take supplements or how much to take. Some support raising the guideline from the 200-600 range it is now to 1000 units a day. On the other hand, a guy at the American Cancer Society warns that more than 2,000 units may be dangerous.
You scientists duke it out. Crabby, having heard rumors of Vitamin D's anti-cancer potential, takes a pill with an extra 400 units. She's also heard there may be some association between vitamin D deficiency and MS, but she'll save that for a future post because she doesn't feel like looking it up at the moment.
And now for the promised Important Instructions.
Have any of you wandered here from some other site, thought there was something you might want to say, (like Hi Crabby, luv ur blog! or whatever) but couldn't quite figure out how to do it? It's not all that obvious.
Fortunately, our good friend Katieo at Sister Skinny has carefully explained the whole process. Go there, read this post, notice that the Sisters have a great blog going on, bookmark the commenting instructions, (and this is the important part) race back here to practice your new-found commenting skill! And then go back to Sister Skinny, of course, and practice a whole bunch more.
