Mercola reports an early study in which rats given niacin after ischemic stroke grew new blood vessels and sprouted nerve cells, improving neurological outcome. Niacin is already the most effective clinical drug for raising HDL cholesterol.

Low levels of vitamin D linked to higher rates of asthma in African American Kids (PR)
Children's National researchers found 86 percent of 85 African American children with asthma had insufficient vitamin D, against 19 percent of 21 healthy children; adjusted odds ran nearly twenty times higher. Lead author Robert Freishtat says more research is needed to establish how.

What is mutton?
Mutton comes from adult sheep, while lamb is meat from an animal in its first year. Chinese tradition holds that it boosts energy and improves circulation, but warns off those with fever, liver disorders or high blood pressure. Hawthorn, radish or ginger can mask its smell.

Kraft to reduce salt in foods by 10% in two years
Kraft plans to cut salt in its North American foods by 10 percent over two years, removing more than 10 million pounds. A cited Stanford study estimates a 10 percent reduction could prevent 500,000 heart attacks and 531,885 strokes among adults aged 40 to 85.

Fruit and vegetables boost ovarian cancer survival
Among 341 women with epithelial ovarian cancer, those eating the most fruit and vegetables before diagnosis were 39 percent less likely to die by 2005. The heaviest meat eaters were 128 percent more likely to die and the heaviest milk-product users 115 percent. The study was observational.

Omega-3 Boosts Brain Function in Boys
Mercola reports neuro-imaging showing DHA supplementation altered activity in cortical attention networks in healthy boys, plus a trial of over 200 young offenders where vitamin, mineral and omega-3/6 supplements cut violent incidents 34% against a 14% rise.

Kick Yourself for the Next Decade
A BMJ paper ties low past vitamin D levels to later colon cancer, but a table on page eight shows the benefit almost vanishes in people with the highest retinol intake, around 3,000 IU a day. Mercola says overlooked vitamin A may explain conflicting results.

How to reduce the risk of heart attack that kills Peter Graves
Peter Graves died at 84 of what his doctor said was likely a heart attack, collapsing outside his Los Angeles home. Most heart attacks follow plaque buildup in the coronary arteries, and nutritionist Colin Campbell is cited for the view that diet drives that buildup and can reverse it.

The Vitamin D Newsletter: More vitamin D studies
A Vitamin D Council newsletter argues the American press is ignoring recent vitamin D research, then reviews new studies, including University of Toronto work suggesting that common variants in the vitamin D binding protein help explain why blood levels respond differently to supplements.

High blood pressure: What you can eat to prevent it (I)
A Lancet study of 8,000 people with a prior heart attack found those whose blood pressure fluctuated were six times as likely to have a stroke as those with stable hypertension. The piece then summarizes dietary approaches, starting with the DASH diet and garlic.

Vitamin D and Calcium Interplay Explored
An ARS-supported study of about 10,000 US adults aged 20 and over underscores vitamin D's role in helping the body use calcium, which may help explain why raising calcium intake alone does not always cut fractures. Many younger and older adults fell below desirable serum levels.

The Lystedt Law: A Concussion Survivor’s Journey
Washington State's Lystedt Law, passed in May 2009, requires any young athlete showing concussion signs to be examined and cleared by a licensed health care provider before returning to play. It is named for Zack Lystedt, permanently disabled after going back into a game in 2006.

High Fructose Corn Syrup - It’s Just Sugar (PR)
A Corn Refiners Association release praises a CBS Evening News report concluding high fructose corn syrup is nutritionally no different from sugar. It quotes CSPI's Michael Jacobson calling the sweetener's “evilness” an urban myth and association president Audrae Erickson.

Is This the New Silver Bullet for Cancer?
Human breast cancer cells treated with a potent form of vitamin D died within days, and tumors in mice shrank by more than half on average, some disappearing. A review of 28 studies covering nearly 100,000 people tied high vitamin D to 43 percent lower cardiometabolic risk.

Processed meats linked to heart disease
A Harvard meta-analysis of 20 studies covering more than 1.2 million people tied each 50-gram serving of processed meat to 42 percent higher heart disease risk and 19 percent higher diabetes risk. Unprocessed red meat showed no significant link, and neither raised stroke risk.

Drinking alcohol prevents overweight/obesity?
An Archives of Internal Medicine study followed 19,000 normal-weight women for 13 years and found those drinking 15 to 30 grams of alcohol a day were 30 percent less likely to become overweight or obese than non-drinkers. The design cannot show cause, and earlier work conflicts.

Vitamin D deficiency is why you get flu and other infections
A University of Copenhagen study in Nature Immunology reports that T cells need vitamin D to activate against bacteria and viruses. Carsten Geisler's team traces the signalling chain from the T cell receptor through the vitamin D receptor gene to PLC-gamma1.
