VITAMIN D UPDATE: Vitamin D linked to children’s language issues. “Mothers who had low vitamin D levels while they were pregnant are more likely to have a child with a language impairment than mothers who had higher levels of the vitamin, according to an Australian study.”

Also: Vitamin D deficiency epidemic among Black people. “A white person will make enough vitamin D by getting exposed to the sun for only 10 minutes. It can take more than two hours for a Black person to get the same quantity of vitamin D.” Note that however pale you are, if you slather sunscreen on every time you go out, you’ll have similar problems.

UPDATE: Patrick Cox sends this piece: Death By Scientific Consensus.

And they’ll be talking about this at Chris Peterson’s Personalized Life Extension Conference later this spring.

ANOTHER UPDATE: Reader DRJ emails: “I was diagnosed with cancer last year and I asked all my doctors to test the Vitamin D levels for myself and my family. (Only one agreed to do it and I had to pay for it myself. The rest claimed I didn’t need the test.) Well, guess what? My Vitamin D levels were very low, as were those of 3 other members of my family. After my test results came back, several of my doctors had their Vitamin D levels tested and they were low, too. As someone I admire likes to say: Heh!” My doctor has been testing patients, with similar results. I try to get reasonable amounts of sun when I can, but I also take 2-4000 units a day.

MORE: From Johns Hopkins: Vitamin D and prostate cancer: “Vitamin D may turn out to be a ray of hope for men with prostate cancer. Laboratory and population-based research suggest that adequate levels of vitamin D reduce the risk of developing prostate cancer and may help suppress the growth and spread of prostate cancer cells in men who already have it.”
