Agricultural Research Service scientists in Ames, Iowa curate a collection of about 60 Hypericum species, and researchers at the Center for Research on Botanical Dietary Supplements are screening 180 accessions for compounds that might fight viral infections, reduce inflammation or aid digestion.

Shocking! This 'Tequila' Sweetener is Far Worse than High Fructose Corn Syrup
Mercola argues that agave nectar is not the traditional plant remedy its marketing evokes but a heavily processed, highly concentrated fructose syrup stripped of nutritional value, and that it is worse for you than high fructose corn syrup.
Food
Meat, Chocolate, Coffee, and Sugar Lead to Food Addiction
Rats with unlimited access to junk food kept eating despite electric shocks and refused ordinary chow for two weeks when the junk food was withdrawn. Researchers found the diet suppressed the dopamine D2 receptor in the brain's reward system, leading to compulsive eating.

Some States See High Rates of Flu Activity, Vitamin D Helps Fight the Illness
CDC reported flu activity elevated in regions 4, 7 and 9 in late March, with Georgia's diagnosis rate at 15.2 percent. A health observer suggests the pattern may relate to larger black populations in those states, since vitamin D deficiency is more common among blacks.

Study: Junk Food Can be Addictive
Rats with unlimited access to junk food gained weight fast and kept eating through foot shocks, while rats on limited access did not, Scripps researchers report in Nature Neuroscience. Artificially suppressing the dopamine D2 receptor produced the same compulsive eating. The work is in animals.

Vitamin D May Protect Against Heart Attack
Cardiologist J. Brent Muhlestein found about two-thirds of 41,000 Intermountain Medical Center patients had low vitamin D, and low levels were associated with later heart attacks, strokes and death. Those brought back to normal had about 30% fewer cardiovascular events.

Vitamin D deficiency may lead to MRSA infection
Analyzing NHANES data from 2001 to 2004, Medical University of South Carolina researchers found 1.2 percent of the population carried MRSA and 28.3 percent were vitamin D deficient. People with serum vitamin D below 20 ng/mL faced a significantly higher risk of MRSA carriage.

Featured Product: Smart for Life Cookies
A look at Smart for Life's cookie diet: chocolate, blueberry and oatmeal meal-replacement cookies sold in 9-day and 2-week programs, the latter for $279. The writer says only users can judge whether they work, and notes baked goods can contain some acrylamide.

Reduced fat intake cuts invasive breast cancer risk
Recalculating data from the Women's Health Initiative diet modification trial, Dayal and Kalia argue average adherence would avoid 7.3 percent of invasive breast cancers in post-menopausal women, and that the trial showed a dose-response relationship the original reporting obscured.
Vitamins
Infants need vitamin D supplements
Researchers estimate only 5 to 37% of US infants meet the American Academy of Pediatrics' 400 IU daily vitamin D standard, and just 1 to 13% get a supplement. Breast-fed babies fare worst, and a formula-fed infant would need about 32 ounces a day to reach 400 IU.
Food
High fructose corn syrup the cause of obesity epidemic, new study suggests
A Princeton study in Pharmacology, Biochemistry and Behavior reports rats drinking high fructose corn syrup gained more weight than rats given table sugar in equal quantity, and that long-term use raised abdominal fat and triglycerides. Bart Hoebel says this holds under their test conditions.

The Vitamin D Newsletter: Vitamin d and heart disease
The Vitamin D Council newsletter summarizes two Annals of Internal Medicine reviews. Pittas and colleagues pooled 32 studies and concluded that lower vitamin D status seems to carry higher risk of hypertension and cardiovascular disease, while supplements' effect on outcomes is unknown.

Vitamin D Deficiency is Why You Get Flu!
A study in Nature Immunology describes how T cells need vitamin D to activate: on meeting an invader the T cell signals the vitamin D receptor gene, whose protein binds vitamin D and then produces PLC-gamma1, letting the cell start fighting the infection.

Mediterranean diet helps infertility in women
Among 161 couples in Dutch fertility treatment, women whose diets most resembled the Mediterranean pattern were 40 percent more likely to conceive than those whose diets were least similar. The study was observational, so it cannot show the diet caused the difference.

Vitamin D Boosts Immunity Against Tuberculosis
No trial has tested whether vitamin D prevents tuberculosis, but the author cites supporting evidence: 86% of 64 children with active or latent TB at a London clinic were vitamin D deficient or insufficient, and a case-control study found lower levels in active TB patients.
Nutrition
Selenium linked to lower risk of diabetes
Following 1,262 French adults for nine years, researchers report in Nutrition & Metabolism that older men in the top third of blood selenium were 50 percent less likely to develop impaired fasting glucose or type 2 diabetes. No benefit showed in women, and high doses can cause poisoning.

Drug Resistant TB a Global Risk; Vitamin D May Help Prevent TB
US tuberculosis cases fell 11.8 percent in 2008, but WHO says drug-resistant TB is rising in Russia, India and China; a third of the 440,000 resistant cases reported that year died. Treating MDR-TB costs about $500 and up to two years, against $20 and six months for conventional TB.

Alzheimer's research news: Novel molecule may prevent and cure Alzheimer's disease
Cambridge and Swedish researchers report in PLoS Biology that an engineered Affibody binds the amyloid beta peptide, blocking plaque formation and breaking up plaques already formed. Fruit flies bred to make it did not develop the fly version of the disease.
