MULTIPLE HEALTH CONCERNS SURFACE AS WINTER, VITAMIN D DEFICIENCES ARRIVE

Tuesday, November 24th, 2009

CORVALLIS, Ore. - A string of recent discoveries about the multiple health benefits of vitamin D has renewed interest in this multi purpose nutrient, increased awareness of the huge numbers of people who are deficient in it, spurred research and even led to an appreciation of it as “nature’s antibiotic.” On issues ranging from the health of your immune system to prevention of heart disease and even vulnerability to influenza, vitamin D is now seen as one of the most critical nutrients for overall health. But it’s also one of those most likely to be deficient - especially during winter when production of the “sunshine vitamin” almost grinds to a halt for millions of people in the United States, Europe and other northern temperate zones.

Analogs of the vitamin are even being considered for use as new therapies against tuberculosis, AIDS, and other concerns. And federal experts are considering an increase in the recommended daily intake of the vitamin as more evidence of its value emerges, especially for the elderly.

“About 70 percent of the population of the United States has insufficient levels of vitamin D,” said Adrian Gombart, a principal investigator with the Linus Pauling Institute at Oregon State University. “This is a critical issue as we learn more about the many roles it may play in fighting infection, balancing your immune response, helping to address autoimmune problems, and even preventing heart disease.”

GREEN TEA SHOWS PROMISE AS CHEMOPREVENTION AGENT FOR ORAL CANCER

Thursday, November 5th, 2009

HOUSTON - Green tea extract has shown promise as cancer prevention agent for oral cancer in patients with a premalignant condition known as oral leukoplakia, according to researchers at The University of Texas M. D. Anderson Cancer Center. The study, published online in Cancer Prevention Research, is the first to examine green tea as a chemopreventative agent in this high risk patient population. The researchers found that more than half of the oral leukoplakia patients who took the extract had a clinical response.

Long investigated in laboratory, epidemiological and clinical settings for several cancer types, green tea is rich in polyphenols, which have been known to inhibit carcinogenesis in preclinical models. Still, clinical results have been mixed.

“While still very early, and not definitive proof that green tea is an effective preventive agent, these results certainly encourage more study for patients at highest risk for oral cancer,” said Vassiliki Papadimitrakopoulou, M.D., professor in M. D. Anderson’s Department of Thoracic/Head and Neck Medical Oncology, and the study’s senior author. “The extract’s lack of toxicity is attractive - in prevention trials, it’s very important to remember that these are otherwise healthy individuals and we need to ensure that agents studied produce no harm.”

REDUCTION IN GLYCOTOXINS FROM HEAT PROCESSING OF FOODS REDUCES RISK OF CHRONIC DISEASE

Wednesday, November 4th, 2009

Researchers from Mount Sinai School of Medicine report that cutting back on the consumption of processed and fried foods, which are high in toxins called Advanced Glycation End products (AGEs), can reduce inflammation and actually help restore the body’s natural defenses regardless of age or health status. These benefits are present even without changing caloric or nutrient intake. The findings, published in the October/November issue of the Journal of Clinical Endocrinology and Metabolism, provide a simple dietary intervention that could result in weight loss and have significant impact on several epidemic diseases, including diabetes, heart disease, and kidney disease.

The findings are the result of a clinical study involving over 350 people which was conducted in collaboration with, and with support from, the National Institute on Aging (NIA). The study builds on earlier research conducted in animal models that demonstrated the effective prevention of these diseases and even the extension of lifespan by consuming a reduced AGE diet.

“What is noteworthy about our findings is that reduced AGE consumption proved to be effective in all study participants, including healthy persons and persons who have a chronic condition such as kidney disease,” said the study’s lead author Helen Vlassara, MD, Professor and Director of the Division of Experimental Diabetes and Aging at Mount Sinai School of Medicine.
