John Cannell's newsletter responds to a Harvard paper by Dennis Kinney and colleagues that accepts the vitamin D theory of autism and adds five environmental toxins. Cannell objects that pollution theories cannot explain the timing, since U.S. air and water were dirtier decades ago.

Despite Anti-Vitamin D Bias, CDC Stumbles on Deficiency Link to H1N1 Deaths
Mercola reads CDC data on 36 U.S. children killed by H1N1 and notes that nearly two-thirds had epilepsy, cerebral palsy or other neurodevelopmental conditions, which he links to childhood vitamin D deficiency, as are the anticonvulsants many of them took.

Vitamin D cuts risk of death from heart disease
Researchers at the University of Colorado Denver and Massachusetts General Hospital analysed blood samples from more than 3,400 adults in NHANES III and found those with low vitamin D were three times more likely to die of heart disease. Lead author Adit Ginde wants a trial.

Vitamin C fights cancer - study
High doses of vitamin C raised survival by 20 percent in mice injected with sarcoma cells, Korean researchers report. Gene expression and wound-healing tests pointed to blocked angiogenesis, with the vitamin altering three genes controlling bFGF, VEGF and MMP2.

Low Vitamin D Increases Flu Death Risk in Kids
Mercola notes that nearly two-thirds of the 36 US children killed by H1N1 had epilepsy, cerebral palsy or another neurodevelopmental condition, all of which he links to childhood vitamin D deficiency, and that anticonvulsant drugs lower vitamin D levels further.

Modest vitamin/mineral deficiencies increase age-related disease (press release)
Scientists at Children's Hospital Oakland Research Institute reviewed hundreds of published studies and concluded that optimal vitamin K intake may help prevent bone fragility, arterial and kidney calcification and cardiovascular disease, supporting Bruce Ames's triage theory.

Vitamin D protects against H1N1 - new evidence
Vitamin D Council president John Cannell circulates a physician's account of a June 2009 H1N1 outbreak at a Wisconsin care facility, where two of about 275 vitamin D-supplemented residents fell ill against roughly 60 of 800 staff, and urges readers to contact their representatives in Washington.
Vitamins
The Simple Inexpensive Way to Radically Reduce Your Risk of Heart Disease
Mercola relays research proposing a mechanism: vitamin D blocks macrophages from taking up cholesterol, so in deficient people those cells fill with it and turn into the foam cells that mark early atherosclerosis. Low vitamin D nearly doubles cardiovascular risk in patients with diabetes.
Vitamins
Pervasive B12 Deficiency Affects Millions – How About YOU?
The Journal of Family Practice reports that B12 deficiency in older people often stems from food-B12 malabsorption caused by atrophic gastritis rather than pernicious anemia. One study put prevalence at 12 percent, and mild memory loss can mask the deficiency.

Vitamin C helps protect your skin (press release)
University of Leicester researchers found that a vitamin C derivative, ascorbic acid 2-phosphate, protected human dermal fibroblasts from DNA damage and promoted wound healing, adding mechanistic support to their earlier finding that DNA repair rises in people taking vitamin C.
Vitamins
Study reveals new role of vitamin C in skin protection (press release)
University of Leicester and Portuguese researchers found that a vitamin C derivative, ascorbic acid 2-phosphate, promoted wound healing and protected the DNA of human skin cells in culture, building on the group's earlier evidence that vitamin C supplements upregulate DNA repair.

Vitamin D and H1N1 Swine Flu *****
Dr. John Cannell's newsletter argues that adequate vitamin D strengthens innate immunity by prompting hundreds of antibacterial peptides, and that the 36 U.S. children who had died of swine flu were much more likely to be vitamin D deficient, a pattern he says the CDC missed in its own data.

IV Vitamin C Used to Recover Terminal Swine Flu Case
Mercola relays Thomas Levy's account of a New Zealand farmer with swine flu and undiagnosed leukemia who was on life support until his family pressed the hospital to give intravenous vitamin C. The hospital agreed reluctantly, and the patient began improving two days later.

Vitamin D: What you need to know
A primer on vitamin D3, or cholecalciferol, which the skin makes in sunlight and the body converts into the hormone calcitriol, said to affect some 2,000 genes. It recommends the 25-hydroxyvitamin D blood test and cites the Vitamin D Council's threshold of 50 for deficiency.

The Vitamin D Newsletter: Vitamin D Studies of Interest
The Vitamin D Council's newsletter rounds up recent studies, opening with H1N1. The author notes 36 US children had died that season and argues CDC data hint at vitamin D deficiency, since nearly two-thirds of them had epilepsy, cerebral palsy or similar conditions.

Vitamin C deficiency may impair brain development
Newborn guinea pigs with moderate vitamin C deficiency had 30 percent fewer hippocampal neurons and markedly worse spatial memory than those fed enough, a University of Copenhagen study found. The authors suggest deficiency in pregnant women may similarly affect infant brain development.
Vitamins
Canada Looks at Vitamin D for Swine Flu Protection
The Public Health Agency of Canada confirmed it will adapt an existing study of vitamin D and severe seasonal influenza to the H1N1 virus, partly to learn whether vitamin D levels explain why most flu cases stay mild. Dr. Mercola urges readers not to wait for the results.
Vitamins
Low vitamin D doubles heart risk in diabetics
Washington University researchers report in Circulation that vitamin D deficiency may double cardiovascular risk in people with diabetes. Without enough vitamin D, macrophage cells take up cholesterol they cannot clear, which builds up in blood vessels and stiffens them.
