This is a huge presentation from GrassrootsHealth, much of it likely inaccessible to the average layman. So let me help. I could certainly use as much knowledge as possible -- and let me come clean about something.
It's weird, at the age of 47, having completed one career and then started a successful company that pays my way even when I'm not there, only to find that I probably should have studied biochemistry instead of mathematics, computer science, and ultimately, business administration. I must have been derailed by my teenage infatuation with layman physics and pop cosmology, which set my course. I ultimately became unsatisfied with high-level math because, I dunno, I didn't smoke dope (at the time). It was just too inapplicable to the practical realities that interested me then. Biology was the farthest thing from my mind, and her I am, decades later, pouring over ever study I can get my computer on.
Computer programming was cool, and it teaches you logic like nothing else, but I got impatient with the stone age way computer time was managed at the university I attended, and I just had to move on.
Alright, on to highlights of Dose-Response of Vitamin D and a Mechanism for Prevention of Cancer, by Cedric F. Garland, Dr.P.H., Edward D. Gorham, M.P.H., Ph.D., Sharif B. Mohr, M.P.H., and Frank C. Garland, Ph.D.
There are a ton of slides here, so I'll highlight a few of what I consider the most notable. First up, placebo vs. intervention. I'd call that significant.
Babes: protect those awesome boobies, wouldja -- not to mention you very lives? Get your vitamin D levels above 30.
Smile. You've been duped by the "experts" and "authorities." But at least they've got their grants from the drug companies. I'm sure that'll work out for you in the end.
Here's one of a great many of similar slides on various cancers illustrating the same thing. Get your level up to 30 and you reduce your risk by half. Get it up to 60-70 and you virtually eliminate your risk.
And here's the mother load. Above 50, and your associative risk of cancer drops to 25%. For women, the real outlier is breast cancer. Get it above 60-70, sweethearts, and good luck. A high amount of fat in your diet isn't going to hurt, either.

Wow, Richard. This is SO telling. I'm now starting to re-think my assumption that the military pollution upstream from us as a kid (dumped in our stream and seeping into our well) was solely responsible for my mother's THREE cancers at age 25. Why? Because her pregnancy diet was obviously horrible since I've had 8 teeth removed due to a tiny palate. She was obviously low in fat soluble vitamins when I was born, about 5 years before she came down with all of these cancers, one of them Hodgkin's lymphoma (lymphomas very prevalent in our family). She also had another rare type of liver cancer not often seen, according to the docs.
The fact is that your body can handle all types of environmental insults with proper nutrition. One of the tribes Weston Prices studied (the ones in the Outer Hebrides) and one of the tribes mentioned by Stephan — can't remember whether it was the Kuna or Kitavans — were exposed to a TON of smoke. They did not appear to suffer any ill effects from it.
I do a lot of medical writing on COPD (emphysema). I'm now wondering whether higher vitamin D levels wouldn't be able to prevent a lot of those COPD cases we see as a "result" of smoking. It's something I've never come across in the medical literature despite reading many, many papers on COPD — since there is some preliminary evidence that vitamin D3 supplementation in pregnancy can prevent asthma (another western disease on the rise). I can say for certain that ALL of the medical literature I've seen on COPD is focused on oxygen therapy and drugs. Some are beginning to talk about "chemoprevention" by developing new drugs tailored to the genetics of the individual (only 15-20% of smokers ever develop COPD) to prevent the disease. I've seen maybe a couple of papers discussing vitamin supplementation. AS usual, the conclusions are "The beneficial effects of vitamin supplementation are not proved."
*sigh* But there's no money in vitamin D3 supplements… the best chemoprevention there probably is. And of course there is no "proof" in the form of a double blind, placeboed trial when the researchers don't want to conduct one.
Richard,
This is terriffic, thanks for posting all this. I've never seen so much vitamin D epidemiology in one place.
From what I've been gathering, there has been lots of non-industrial populations who smoked without the western-style diseases associated with it. 70% or thereabouts of Kitavans smoke, and about the same for Massai.
I have long speculated that smoking is not the root cause of these diseases, but that inflammatory factors like grains and vegetable oils are. The smoking sets off the disease, and with deficiencies like vitamin D, the body can't deal with the damage.
Just speculation though. Of course, with the politicized anti-smoking gravy train worldwide, now, this kind of speculation would go over like a lead balloon. Few care about facts, anymore.
Dear Richard, your blog is better than ever! Love to see these studies' references telling what we allways knew after all: a paleolithic lifestyle is what we were made for!
Thanks, Ricardo. I'm sure I would be able to say the same thing about yours, were I able to read it.

[...] Keep in mind that by sugar, I don't just mean sugar the white stuff. I mean sugar, all the processed foods and drinks (even fruit juice) that contain it, and things that get metabolized into glucose like starches and grains and all the products that contain them. A low sugar diet is one that focusses on meat, fowl, seafood, natural fats (animal, coconut, olive), non-starchy vegetables, moderate fruit focussed on berries, and maybe some nuts and high-fat dairy. Bottom line? Eat meat, fat, veggies. Be sure to get adequate vitamin D. [...]
The data on vitamin D preventing cancer is now as extensive as the data on smoking causing cancer!! Take a look at http://www.vitaminD3world.com for some good summaries of the data
Monica, you mentioned you think there is no double blind placebo study on vitamin D an cancer prevention–there is one! It was published in 2007 by Lappe and showed a 60-77% reduction in the incidence of cancer over a four year period. You can see a review of this and links to the study on http://www.vitaminD3world.com
As a result of this study the Candian Cancer Society started recommending that everyone take vitamin D to prevent cancer. It is amazing how little press coverage this received else where in the world
Perhaps not surprising Vitamin D is also linked to Alzheimer’s (which, has been nicknamed “Diabetes Type 3″ by a few sources), and Parinson’s Disease, as well as Schizophrenia.
Check out this article for some of those other Vitamin D odds and ends, with oodles of citations: Vitamin D, Diabetes, Neurcognitive Diseases, and Supplementation.
There is some interesting data suggesting that keeping your vitamin D level optimal will prevent colds, flu and in particular H1N1 (swine Flu).

Another great post Richard, thanks for sharing and explaining a few of the many great bits of wisdom one can get on Vit. D from the Grassroots Health website… an awesome resource.
Regarding your speculations about smoking and cancer, no doubt Vitamin D nutrition are factors there, far more so than most would guess today. But when you look at a healthy pair of longs, all that really soft pink tissue… I also can’t imagine that tar and the gazillion chemicals in cigs are very good for it either! What the biggest “cause” of the cancer is… I’m open to debate.
As an aside… your recent post led to me commenting that we had that in common, and now I see another — I too started out with a love of physics and cosmology, in my case leading to starting up at Univ. of Rochester as an Astrophysics major… only to ditch it after one year… and eventually majoring in philosophy instead. I have no regrets on that decision.
Typed too fast… my reference to the earlier post… I meant your Christmas time Pink Floyd one.
Maybe let me see what I can come up with tonight. I’m gonna have to think. Ah, I have and idea, not PF, but very classic and rare.
