A Psychosomatic Medicine study from the University of Tokyo found folate and vitamin B6 intake inversely associated with depressive symptoms in early adolescence, with reductions of up to 40 and 28 percent. Riboflavin helped girls only; B12 showed no link.

B vitamins prevent dementia
In an Oxford trial, 168 volunteers with mild cognitive impairment took high-dose B12, folate and B6 for two years; brain shrinkage averaged 0.76 percent a year against 1.08 percent on placebo. Researchers did not test cognition, and a Dutch trial using lower doses found no benefit.

Magic mushroom ingredient eases anxiety in cancer patients
Twelve adults with advanced-stage cancer took psilocybin at 0.2 mg per kg and a placebo in two sessions weeks apart. No severe anxiety or unsafe physiological response appeared, and anxiety scores improved at one and three months, a small Archives of General Psychiatry study reports.

Could This Simple Habit Actually Reduce Cancer and Diabetes by 50%?
Reuters reports that vitamin D influences more than 200 genes, among them genes tied to cancer and multiple sclerosis, acting through receptors that bind specific spots on the genome. Mercola cites over 800 cancer studies and claims optimal levels can halve the risk of several cancers.

High selenium linked to lower risk of bladder cancer
A meta-analysis of studies from the US, Belgium, Finland and the Netherlands linked higher selenium in serum and toenails to as much as 39 percent lower bladder cancer risk. The effect showed up mainly in women, which researchers attribute to sex differences in how selenium accumulates.

How Was Your Veal "Prepared"? Like This Video?
Mercy For Animals released undercover video, narrated by Bob Barker, of newborn calves chained by the neck in two-foot stalls at Buckeye Veal Farm in Ohio. Costco condemned the conditions and now requires untethered calves; Buckeye and buyer Atlantic Veal dispute any mistreatment.

More Americans use prescription drugs - CDC
An NCHS data brief reports the share of Americans taking at least one prescription drug in the past month rose from 44% to 48% over a decade, use of two or more from 25% to 31%, and five or more from 6% to 11%. In 2007-2008 that included 9 of 10 older adults.

Who Knew this Vitamin Could Prevent Mold Allergies?
A Journal of Clinical Investigation study reported that stronger Th2 reactivity to Aspergillus fumigatus, a common household mould, went with lower average blood vitamin D, leading researchers to suggest vitamin D may help treat or prevent allergy to it.

Vitamin D Linked To Cancer and Autoimmune Disease Genes
Reuters reports on Genome Research findings that vitamin D influences more than 200 genes, including ones tied to cancer and autoimmune disease, acting through receptors that bind specific spots on the genome. Mercola argues other work puts the count closer to 3,000.

Where can I learn about prostate or ovarian cancer?
September marks both National Prostate Cancer and National Ovarian Cancer Awareness Month. Using National Library of Medicine material, the post explains how tumors form and spread, then points to NCI, CDC and FTC resources and an FDA warning about online cancer fraud.

Hurricanes: What you need to know
Preparing for a hurricane starts with an emergency supply kit and a to-go bag: water, non-perishable food, a battery or hand-crank radio, flashlight, first aid kit, medications, bedding and copies of key documents. Then set family meeting places and contacts.

Does drinking alcoholic beverages provide any benefit at all?
Businessweek said two or three drinks a day helped adults outlive teetotalers, but the study behind it found only an association: non-drinkers were 49% more likely to die over 20 years, heavy drinkers 42% more likely than moderate ones. It was observational, so it cannot establish cause.

Don't Avoid This Daily, Healthful Food Because it's Been Mislabeled as 'DIRTY'
Mercola retells the history of the chicken and the egg, arguing that Americans have been wrongly taught that chickens are dirty, stupid carriers of disease, and noting the British scientists who concluded the chicken came first.

Eight Foods that Could be Disastrous for Your Health
Researchers told the Ecological Society of America that transgenic canola is growing freely in parts of North Dakota, the first US finding of a GM crop on uncultivated land. Cynthia Sagers said plants resistant to two herbicides show the feral populations have persisted for generations.

Salmonella with Your Omelet? Don't forget Stroke and Ovarian Cancer
An opinion piece urging readers to stop buying eggs, citing salmonella, cholesterol, claimed links to diabetes and ovarian cancer, antibiotic residues, and undercover video of bloody, insect-covered eggs at a California farm.

Omega-3 fatty acids don't cut risk of heart disease?
In 4,837 heart attack survivors aged 60 to 80, low doses of EPA and DHA or of ALA did not cut major cardiovascular events, researchers reported at the 2010 European Society of Cardiology Congress. Many variables were in play, so the trial does not settle the question.

Eating eggs, breastfeeding affect risk of diabetes mellitus (type 2)
Women who never breastfed were nearly twice as likely to be diagnosed with type 2 diabetes as those who did, in a study of 2,233 women aged 40 to 78. A separate Harvard analysis of two large trials found diabetes risk rose with the number of eggs eaten.

In memory of one of the greatest contributors to human understanding of vitamin D...
An obituary for vitamin D researcher Dr. Frank C. Garland, who with his brother Cedric first linked vitamin D deficiency to cancer in a 1980 paper and won the Arnold-Rikli Prize. Evidence now covers as many as 20 vitamin D-responsive cancers.
