Something for everyone ping.

I had an email exchange with Holick a few weeks ago (I saw him make a presentation at the nephrology society meeting a few years ago) and he takes 2,000 of D3 a day.

I think I heard that they are finding a correlation between one’s lattitude and the incidence of osteoperosis.

At least as regards cancer, the claims in that article are likely overstated, see for example:

http://www.ncbi.nlm.nih.gov/pubmed/17971526?dopt=Abstract

"BACKGROUND: Vitamin D has been hypothesized to reduce cancer mortality through its effects on incidence and/or survival. Epidemiologic studies of the association of 25-hydroxyvitamin D [25(OH)D] and the risk of cancer, however, have been largely limited to incident cancers at a few sites. METHODS: A total of 16,818 participants in the Third National Health and Nutrition Examination Survey who were 17 years or older at enrollment were followed from 1988-1994 through 2000. Levels of serum 25(OH)D were measured at baseline by radioimmunoassay. Cox proportional hazards regression models were used to examine the relationship between serum 25(OH)D levels and total cancer mortality (in the entire population or according to race/ethnicity, sex, age, and retinol status) and mortality from specific cancers. Because serum was collected in the south in cooler months and the north in warmer months, we examined associations by collection season. All statistical tests were two-sided. RESULTS: We identified 536 cancer deaths in 146,578 person-years. Total cancer mortality was unrelated to baseline vitamin D status in the entire population, men, women, non-Hispanic whites, non-Hispanic blacks, Mexican Americans, and in persons younger than 70 or 70 years or older. We found no interaction between vitamin D and season or vitamin D and serum retinol. Colorectal cancer mortality was inversely related to serum 25(OH)D level, with levels 80 nmol/L or higher associated with a 72% risk reduction (95% confidence interval = 32% to 89%) compared with lower than 50 nmol/L, P(trend) = .02. CONCLUSIONS: Our results do not support an association between 25(OH)D and total cancer mortality, although there was an inverse relationship between 25(OH)D levels and colorectal cancer mortality."

Another excellent source of information on Vitamin D and its relationship to health is The Vitamin D Council.

I’ve quit trusting in medical knowledge about nutrition. There doesn’t seem to be any truly “settled science” underlying many (strongly held) assumptions. (My diabetic family still hasn’t heard about low carb diets from their doctors.)

They’ve been wrong about vitamin D and I’ll add another one, vitamin C. Vitamin C cures atherosclerosis and lowers LDL cholesterol. It doesn’t take megadoses either (total of 1000 mg will do). Many older people have symptoms of low grade scurvy and don’t know it. I didn’t and my doctor didn’t recognize it. Linus Pauling was right on this 40 years ago.

Great post and timely (at least for me). I was mentioning this whole Vitamin D thing to my sweetie over the weekend.

Thanks so much!

Wait, I just had a brainstorm — “Taking Vitamin D with the Stars”!!! It’s GENIUS.

;’) Thanks decimon.

They get plenty of sun and plenty of Vitamin D

Average life expectancy: 45

That was my old endocrinologist’s “fix” for primary hyperparathyroid disease. 50,000mg caplets of vitamin D, when if he had tested for that long before that, I would’ve had it fixed long ago.

Good for sugar too...
