In a 12-week trial of 81 young people at very high risk of psychosis, 4.9 percent of those given 1.2 grams of omega-3 fatty acids daily developed a psychotic disorder, against 27.5 percent on placebo. Researchers put the number needed to treat at four.

Krill Oil is 'Safe, Well Tolerated and Effective'
Four weeks of krill oil supplements raised EPA and DHA levels in overweight and obese men and women with no indication of adverse effects on safety measures, a new study found. Mercola says he prefers krill oil to fish oil, given contamination of the fish supply.

Indian herb preparation prevents diarrhea
Brijesh and colleagues in Mumbai tested a hot water extract of unripe Aegle marmelos fruit pulp, long used in Indian medicine for diarrhea. It killed Giardia and rotavirus and curbed bacterial adherence and cholera toxin, but did not affect six bacterial strains.

The Vitamin D newsletter: Another autism case report
The Vitamin D Council gives an entire newsletter to one mother's unedited case report of her son's autism, which began around age 2.5 with sleeplessness, anxiety, obsessive repetitive questions, sensory aversions, toe-walking and self-stimulating behaviors.
Diet
ketogenic diet for seizures
The ketogenic diet, roughly 80 percent of energy from fat, helps two of three children with epilepsy and stops seizures entirely in one of three. It is not nutritionally balanced, so patients need close monitoring, vitamin supplements and a dietitian on their medical team.
Supplements
Vitamin C, E, Omega 3-fatty acids prevent pancreatic cancer
In a San Francisco Bay Area case-control study, the highest intakes of vitamins C and E were tied to 31 and 33 percent lower pancreatic cancer risk and omega-3s to 53 percent lower, while high saturated fat intake was tied to 60 to 160 percent higher risk. Vitamins from food showed no link.

Breastfeeding good for both the baby and the mother
A review by Stuebe in Reviews in Obstetrics and Gynecology reports infants who are not breastfed face higher risks of infection, childhood obesity, diabetes, leukemia and SIDS, while mothers who do not breastfeed face higher risks of premenopausal breast cancer, ovarian cancer and diabetes.

Vitamin E may boost immune response triggered by flu vaccine
Japanese researchers measured immune response in 153 nursing home residents averaging 84.4 years and 95 health workers, before and after trivalent flu vaccination. Among the elderly, only vitamin E tracked significantly with response to A/H1N1 and B, suggesting it may help maintain that response.

Vitamin E may boost memory in older people - study
Aged rats fed a vitamin E-supplemented diet learned a water maze faster and retained their memory, while unsupplemented rats kept only 40 percent of theirs. The compound PQQ had a similar effect. The authors conclude vitamin E may ease age-related cognitive decline.

Cancer's Secret Weakness
Herbalist Donnie Yance argues herbs act more like foods than drugs, producing many effects at once and supporting health at a basic level, and that they lose that quality once manipulated into man-made pharmaceuticals.

Doctors Advised to Take Vitamin D During Flu Epidemic
A 2009 journal article by University of Virginia researchers recommends testing and treating health workers and patients for vitamin D deficiency during the swine flu pandemic, arguing the deficiency can precipitate the virus. No health agency recommends vitamin D to prevent flu.

Echinacea next big thing in fighting swine flu?
In laboratory tests reported in Virology, a commercial Echinacea purpurea extract inactivated human H1N1, H5 and H7 avian and swine-origin influenza viruses, apparently by blocking viral entry into cells, and produced no resistant variants, unlike Tamiflu.

Fat intake increases prostate cancer risk
Comparing 512 prostate cancer patients with 838 men without the disease, University of Nottingham researchers found the highest intakes of total, saturated, monounsaturated and polyunsaturated fat carried 2.3 to 2.7 times the risk of the lowest intakes.

Multiple Sclerosis News: Drug, Vitamins and Sunshine
The FDA approved Ampyra on January 22 to improve walking in multiple sclerosis, with reported 10-30% gains in walking speed but side effects including seizures if overused. Separate studies point to nutrient shortfalls in MS patients and link low vitamin D to a higher risk of relapse.

Blueberry Boosts Memory
Volunteers in their 70s with early memory decline who drank 2 to 2.5 cups of blueberry juice daily for two months did significantly better on learning and memory tests than a control group. The authors call the findings preliminary but encouraging.

Vitamin D May Cut Colon Cancer Risk
An EPIC analysis of 520,000 people in ten Western European countries, published in the BMJ, found those with the highest blood vitamin D were 40 percent less likely to be diagnosed with colorectal cancer. Levels above 75 nmol/L brought no further reduction.

Lower Salt Intake Lowers Cardiovascular Risk
A modeling study in the New England Journal of Medicine estimates that cutting daily salt intake by 3 grams would prevent 60,000 to 120,000 coronary heart disease cases, 32,000 to 66,000 strokes and 44,000 to 92,000 deaths a year, saving $10 to $24 billion.
