A New England Journal of Medicine study found Merck's cholesterol drug Zetia less effective than the cheap vitamin niacin at reducing artery buildup in people already taking statins. It is the third study to question Zetia and the related Vytorin, which earn Merck billions a year.

Milk in iron-fortified fruit juices boost absorption of the mineral
In vitro tests at the University of Valencia found that adding skimmed milk to iron-fortified grape, orange and apricot beverages raised iron retention, transport and uptake by up to four times, outperforming caseinophosphopeptides. Human studies are still needed, the researchers said.

Is Drinking Tea or Coffee the Smarter Choice?
Mercola asks why coffee, which he says supplies no vitamins, minerals or enzymes, became the world's most popular drink, crediting taste and the caffeine boost, and notes that decades of research still conflict over what it does to health.
Minerals
Too much selenium linked to high levels of cholesterol
A Journal of Nutrition analysis of 1,042 UK adults found those with higher blood selenium had 8 percent higher total cholesterol and 10 percent higher non-HDL cholesterol. The study found only an association; whether selenium raises cholesterol is uncertain.

Study Links Fluoride to Premature Births (press release)
A news release on SUNY research presented to the American Public Health Association: using 1993-2002 New York hospital data and adjusting for age, race, poverty, hypertension and diabetes, the researchers tied water fluoridation to higher preterm birth risk, most so among the poorest women.
Food
Choosing Between Raw Milk and a Dead, White Liquid
Mercola presents a video interview with journalist David E. Gumpert, who argues Louis Pasteur developed his heat treatment for wine rather than milk, and that pasteurization's credit for cutting childhood illness is exaggerated because sewers and cleaner water arrived at the same time.
Diet
Diet Plans May Affect Mood
An Australian trial put 106 dieters on a low-fat or a low-carb plan for a year. Both groups lost about 30 pounds and both felt better at first, but the mood lift faded for the low-carb group while it held for the low-fat one.

Drinking Milk Leads to Lower BMI in Children
In a doctoral thesis covering 120 healthy eight-year-olds, children who drank whole milk daily weighed about 4 kilograms less than their peers, with no similar result for medium- or low-fat milk. Author Susanne Eriksson says she does not know why.
Supplements
Antioxidants May Help Prevent Flu
University of Alabama researchers led by Sadis Matalon report that influenza's M2 protein disrupts lung epithelial cells' ability to clear liquid, and that treating cells beforehand with glutathione ester or protein kinase inhibitors prevented that damage.
Vitamins
Some Data on Vitamin D Supplementation
The Institute of Medicine's 1997 adequate intakes run from 200 IU a day under age 51 to 600 IU past 70, far below the 4,000 to 6,000 IU some experts recommend. Reinhold Vieth argued in 1999 that 200 IU prevents osteomalacia but not osteoporosis.
Food
Red Meat, Processed Meats May Raise Prostate Cancer Risk
Following 174,343 US men for nine years, National Cancer Institute researchers recorded 10,313 prostate cancers and found the highest red meat intake carried 12 percent more total risk and 31 percent more advanced disease. Nitrite and nitrate tracked with 24 and 31 percent higher risk.
Minerals
Iodine Supplements May Boost Children's Mental Power
In a New Zealand trial, 184 mildly iodine-deficient children took either 150 micrograms of iodine or a placebo daily for 28 weeks. Those given iodine scored better on two standard cognitive tests of problem-solving.
Diet
Processed foods linked to high risk of depression
A British Journal of Psychiatry study of 3,486 Whitehall II participants found people eating mostly processed meat, fried food, sweets and refined cereals reported more depression five years later than those on whole foods. Folate, omega-3s or lifestyle may explain the gap.
Vitamins
Multivitamins may help cut allergy risk
A Swedish study of more than 2,000 eight-year-olds found current multivitamin use unrelated to allergic rhinitis, eczema, asthma or sensitization. Children who started supplements before age four were 39% less likely to have allergic disease, which the authors call a suggestion, not proof.

WHO Experts Say H1N1 Pandemic Flu Vaccine Safe
WHO's Strategic Advisory Group of Experts on Immunization reviewed clinical trial data and national regulatory decisions and concluded the H1N1 vaccines are safe, recommending a single dose for everyone over six months, use in pregnant women, and co-administration with seasonal vaccine.

Obama lifts HIV ban
President Obama announced that the 1987 ban barring foreigners with HIV from entering the United States will end, with the rule published Monday and taking effect after a 60-day wait. Green card applicants will no longer need an AIDS test, and people with HIV may visit as tourists.
Biotics
Friendly Bacteria Blunt Anti-Nutrient Action
Phytase enzymes from Bifidobacterium strains cut phytate and phytic acid, compounds that block mineral absorption, and high-fiber bread fermented with the bacteria held significantly less phytic acid than traditionally baked bread. Mercola notes fermentation dates back millennia.

This is your brain on fatty acids (Press Release)
Johns Hopkins researchers report in Neuron that palmitate, a fatty acid abundant in the brain, marks NMDA receptors and steers them to spots on the cell membrane where memory circuits form. The modification reverses, which the team says opens ways to manipulate memory.
