Mercola and Ori Hofmekler describe glutathione, a tripeptide of cysteine, glutamate and glycine present in every cell, as the body's master antioxidant, and set out how it differs from the similarly named glutamine and glutamate.

Walnuts Slow Prostate Tumors
Mice with prostate tumors that ate a walnut quantity a man could easily match showed controlled tumor growth and changes in genes governing tumor growth and metabolism. Walnuts supply omega-3 fats and antioxidants, and clinical studies link them to lower cardiovascular risk.

Walnuts and low fat diet may curb growth of prostate cancer
Prostate tumors grew slowly in mice fed a diet with 20 percent of calories from walnuts - about as slowly as on a 5 percent fat diet - while a 20 percent fat diet sped growth. Paul Davis says a man would need roughly 500 calories of walnut oil for a comparable effect.

Cooling Inflammation for Healthier Arteries
USDA-funded Tufts researchers report that avenanthramides, phenolic compounds in oats, lower the expression of inflammatory molecules by inhibiting factors that activate proinflammatory cytokines, suggesting a benefit against atherosclerosis beyond oats' cholesterol-lowering effect.

Breastfeeding Saves Lives and Money
A Pediatrics study estimates that if 90 percent of US babies were breastfed for six months, about 900 lives and billions of dollars could be saved by preventing illnesses including stomach viruses, ear infections, asthma, juvenile diabetes and SIDS.

Earthquake baja california
A magnitude 7.2 quake struck 26 km southwest of Guadalupe Victoria, Baja California, at 3:40 p.m. PDT, 10 km deep. Appended are USGS location details and Doug Copp's advice to curl up beside bulky objects rather than duck under desks or cars.

Trial results show vitamin D helps prevent flu
In a randomized, double-blind trial of Japanese schoolchildren published in the American Journal of Clinical Nutrition, influenza A struck 10.8 percent of those taking 1,200 IU of vitamin D3 daily against 18.6 percent of controls, a 48 percent lower risk.
Supplements
Are You Getting the Right Type of Omega-3 Fats?
Mercola separates the marine omega-3s EPA and DHA, backed by decades of heart research, from the ALA added to many supermarket foods, which the body converts poorly. Americans spend $2.6 billion a year on omega-3 supplements and fortified foods.

Jennifer Hudson weight loss 2010
Hudson has signed on as a Weight Watchers spokesperson seven months after giving birth, though whether her weight loss came from the company's products or services is unknown. A 2005 comparison of four diets ranked Weight Watchers third, with an average 3.0 kg loss over a year.

Vitamin D and Urinary Incontinence (press release)
Researchers at SUNY Upstate Medical University studied 1,961 women and found low vitamin D levels predicted pelvic floor disorders, with urinary incontinence twice as likely in deficient women. The authors suggest treating insufficiency could improve pelvic muscle strength.

Taking multivitamins may raise breast cancer risk
Following 35,000 Swedish women aged 49 to 83 for a decade, researchers found those taking multivitamins were 19 percent more likely to be diagnosed with breast cancer. The design cannot show cause, and the authors note supplement users may already have been at higher risk.

The Vitamin D Newletter: Update on Autism and Vitamin D
The Vitamin D Council newsletter summarises three Swedish papers it says support a vitamin D theory of autism, among them a Karolinska study in which the 10 adult psychiatric outpatients with autism had the lowest 25(OH)D levels of any group, averaging about 12 ng/ml.

Diet and Exercise Beat Drugs for Diabetes Heart Risks
Four studies in the New England Journal of Medicine found no heart benefit for diabetics from lowering systolic pressure with antihypertensives, from adding an HDL-raising drug, or from two blood sugar drugs. Mercola argues weight loss, activity and nutrition matter more.
Minerals
Caution: Low Levels of This Key Mineral Could Shrink Your Lifespan ...
Mercola reports on research finding that men who ate the most calcium, nearly 2,000 mg a day and none from supplements, were 25 percent less likely to die over the next decade. Researchers suggest calcium may act by lowering blood pressure, cholesterol or blood sugar.

Cola may lower sperm counts
A Danish study of more than 2,500 young men found those drinking a quart or more of cola a day averaged 35 million sperm per mL against 50 million in non-drinkers. It was not a trial, and the researchers suggested lifestyle rather than caffeine may explain the difference.

Flavonoids rich foods reduce heart risk
Among 34,489 postmenopausal women followed 16 years in the Iowa Women's Health Study, higher anthocyanidin intake tracked with less coronary heart disease and lower total mortality, and top-quintile flavanone intake with 12 percent lower mortality. No link appeared for stroke deaths.

Eating dark chocolate to lower blood pressure?
In a small German trial of 102 people with prehypertension or stage 1 hypertension, 6 grams of dark chocolate a day for three months lowered blood pressure 2.3 mm Hg from baseline; 25 grams lowered it 1.9 mm Hg and added 0.8 kg of weight. The trial had no control group.
