A Nottingham University meta-analysis of 40 studies from 1980 to 2007 found people with asthma took in significantly less vitamin A, and those with severe asthma about 50 percent less than those with mild disease. Vitamin E intake showed no link to asthma risk.

Mediterranean Diet Linked to Lowered Risk of Depression
Following more than 10,000 Spaniards for about 4.5 years, researchers found those who stuck with the Mediterranean diet were half as likely to become depressed as those who abandoned it, though they say the relationship may not be one of cause and effect.

Once again study suggests high vitamin D cuts breast cancer risk
Rejnmark's Danish case-control study of 142 women with breast cancer and 420 without found those in the top tertile of serum 25-hydroxyvitamin D were 48% less likely to have the disease, with the same pattern in receptor-positive and receptor-negative tumors.

How Much Vitamin D Do You Really Need to Take?
Mercola revisits vitamin D dosing, noting the U.S. RDA of 400 IU was set to prevent rickets and arguing it does nothing for cancer, heart disease or infection, while summer sun on the skin can generate roughly 20,000 units.

Low vitamin D linked to higher risk of breast cancer
Among 166 women being treated for breast cancer, nearly 70 percent had low blood vitamin D, with the lowest levels in those with late-stage disease and in non-Caucasian women, University of Rochester researchers reported. The average level was 27 nanograms per milliliter.
Minerals
Zinc Deficiency is a Global Concern
Mercola cites estimates that as many as 2 billion people eat zinc-deficient diets, including about 12 percent of Americans and perhaps 40 percent of the elderly, and a study finding DNA damage from only minor deficiency. He adds that existing zinc tests are poor.

Vitamin K3 may help fight breast cancer - study
Researchers at Keio University found vitamin K3 killed MCF-7 breast cancer cells in culture, fragmenting DNA and disabling mitochondria via reactive oxygen species and caspase-7 and -9. They suggest it might prove useful in breast cancer chemotherapy.

Flavorful Fruit and Veggie Wraps Inspire Tasty Creations
ARS researchers and Origami Foods developed edible sheets made from fruit and vegetable purees, in flavors like mango, strawberry, tomato-basil and carrot-ginger, plus meltable glaze sheets. The wraps run 75 to 90 percent produce with no additives or preservatives.

Water Hardness Plays a Role in Removing Bacteria from Chicken Skin
ARS researchers in Athens, Georgia rinsed broiler chicken carcasses five times in very hard, moderately hard and soft water, and found soft water removed up to 37 percent more bacteria, including Campylobacter, Staphylococcus and Pseudomonas, from the skin.

Blacks, Hispanics at higher risk for swine flu
A New York Daily News report by Juan Gonzales said blacks and Hispanics are more susceptible to swine flu infection and suggested vitamin D as a preventive, and argued the CDC grew reluctant to report the ethnic disparity as the death toll rose.

Fat Deficiency Kills More People Every Year than Breast Cancer
Harvard researchers modeling 12 dietary, lifestyle and metabolic risks put omega-3 deficiency sixth among preventable killers, at 72,000 to 96,000 US deaths a year. Other cited work tied omega-3s, especially with CoQ10, to lower blood pressure in kidney disease, and low levels to depression.
Diet
Mediterranean diet linked to reduced risk of depression
Researchers surveyed 10,094 healthy Spanish adults about their diets and counted 480 new cases of depression over 4.4 years. Those who adhered most closely to a Mediterranean diet had a more than 30 percent lower risk than those who adhered least, even after other risk factors.

Mushroom, green tea cut breast cancer risk by 89 percent
In a southern Chinese case-control study of 1,009 breast cancer patients and a similar number of healthy women, those eating 10 or more grams of fresh mushrooms, or 4 grams dried, each day were 64 percent less likely to have breast cancer. The paper also weighed mushrooms and green tea together.

Curry and turmeric help smokers with head and neck cancer
Researchers testing curcumin against head and neck squamous cell carcinoma cell lines found it blocked nicotine from activating cancer-causing cells, suggesting curry powder and turmeric might counter nicotine's effect in smokers. Presented at the 2009 AAO-HNSF meeting.

Two findings: elderly Japanese drinking seven or more cups of green tea a day were less likely to die prematurely over six years in a cohort of 14,001, though cancer deaths showed no link; and in lab tests the green tea compound EGC raised a bone-building enzyme's activity by up to 79 percent.
