A question-and-answer rundown on the 2009 H1N1 virus: where its genes came from, its common symptoms, the 26 states reporting widespread flu activity as of September 19, 2009, and the FDA's September 15 approval of four H1N1 vaccines.

Can You Really Extend Your Life Span with this Antioxidant?
Mercola reviews resveratrol, the grape and red wine polyphenol that extended yeast lifespan in 2003 research by activating the sirtuin1 gene and has since been linked to longer life in worms, flies, fish and mice, and to anti-cancer and cardiovascular effects in other studies.

Vitamin D and Calcium Act Jointly to Prevent Cancer
Peterlik and colleagues argue in Anticancer Research that vitamin D and calcium jointly regulate cell growth, listing three ways 1,25-dihydroxyvitamin D3 and extracellular calcium interact, and suggest the two may work better taken together than alone.

Nutrition Notes: Seafood Choices for Your Health and a Healthy World
Karen Collins names fish that are both low in contaminants and sustainably caught: wild salmon, Atlantic mackerel, sablefish, Arctic char, sardines and farmed rainbow trout, plus U.S. farmed catfish, tilapia and shrimp. Americans ate six times more red meat than seafood in 2007.

Got hypertension? Use vitamin D!
A review in Nature Reviews Cardiology by S. Pilz and colleagues concludes vitamin D sufficiency promotes lower arterial blood pressure, though not every trial agreed. The authors suggest supplementing patients with hypertension whose 25-hydroxyvitamin D falls below target.

IV Vitamin C Used to Recover Terminal Swine Flu Case
Dr. Mercola relays a case report from Dr. Thomas Levy: a New Zealand farmer hospitalised with swine flu and undiagnosed leukemia kept deteriorating on Tamiflu and antibiotics until his family pressed the hospital to try intravenous vitamin C, after which staff noted signs of improvement.

New Harvard Paper on Autism
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.
Diet
7 Reasons to Eat More Saturated Fat
Excerpting Michael and Mary Eades' The 6-Week Cure for the Middle-Aged Middle, Mercola lists claimed benefits of saturated fat: lower lipoprotein(a), calcium incorporation into bone, protection of the liver from alcohol and painkillers, and lung surfactant, whose fat is all saturated.

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.

Alzheimer's prevention: Exercise tops the list
With 35 million people worldwide estimated to have Alzheimer's, this piece argues exercise remains the best-supported prevention. Mice allowed to exercise had 50 to 80% less brain plaque, and in a Columbia study of 1,880 New Yorkers the healthiest diets tracked with 40% lower risk.

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.

Your brain on fat -- mechanisms of overeating
UT Southwestern researchers report that palmitic acid, a saturated fat in butter, cheese, milk and beef, reaches the brain and blocks appetite-suppressing signals from leptin and insulin. Senior author Deborah Clegg says the effect lasts about three days, which may explain Monday hunger.
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.

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.
