CHICAGO (Reuters) - The "sunshine vitamin," vitamin D, is increasingly seen as vital to health, yet more Americans are not getting enough, U.S. researchers said on Monday. Analyzing data from government health surveys, researchers from the University of Colorado Denver School of Medicine found three out of four Americans had "insufficient" levels of vitamin D, up from about one out two 20 years ago-

"The common culprit is soy, a plant that contains chemicals with estrogen-like and anti-estrogenic properties - making it a nutritional minefield for breast cancer survivors. While Western diets are relatively low in soy - compared with the typical diet in Asia, where people eat soy daily - the percentage of Americans consuming soy at least once a week has increased from 15% in 1997 to 28% in 2003. In the meantime, studies on the effect of soy on breast cancer recurrence and mortality have been conflicting, with some showing that it can reduce risk, while others show an elevated rate of recurrent disease among high soy consumers. Now the largest study to date of soy's effect on breast cancer suggests that eating soy, even in large amounts, may not be harmful after all, and may even reduce recurrence and death from the disease. But while the findings are intriguing, not all doctors are ready to tout the benefits of tofu

"NEW YORK (Reuters Health) - People who want to maintain a healthy weight over time shouldn't obsess about their fat intake, new research shows. The percentage of calories that a person got from fat, as opposed to protein or carbohydrates, had nothing to do with how much weight they gained in the coming years, the research team found. The kinds of fat they ate didn't matter either, Dr. Nita Forouhi of the Institute of Metabolic Science, Addenbrooke's Hospital, Cambridge, UK and her colleagues found. The findings, Forouhi noted in an email to Reuters Health, show that "it is more important to aim for a healthy lifestyle including a balanced healthy diet and regular physical activity, than to focus on fat intake alone as a factor for weight gain.""

"Despite its dubious beginnings, fad-dieting gained mass appeal in the 19th century. In 1829, Presbyterian minister Sylvester Graham touted the Graham Diet - centered on caffeine-free drinks and vegetarian cuisine, and supplemented by the eponymous Graham Cracker - as a cure for not just obesity but masturbation (and the subsequent blindness it was thought to cause.) The diet became so popular that the students of Oberlin College were forced onto it for a brief period in the 1830s before they successfully rebelled through mass dissent in 1841. Thirty-five years later, an English casketmaker named William Banting became famous by pioneering the concept of a low-carbohydrate diet, which helped him lose 50 lbs. He published his results in the 1864 "Letter on Corpulance," and the plan became so popular that "banting" became a synonym for dieting across Britain. "

"CHICAGO (Reuters) - Post-menopausal women who have three to four alcoholic beverages a week of any sort have a significantly higher risk that their breast cancer will come back, U.S. researchers said Thursday."

"NEW YORK (Reuters Health) - Want to keep your eyesight sharp as you age? Eating lots of fish packed with healthy omega-3 fatty acids could help, new research suggests. Among 1,837 people who had early signs of age-related macular degeneration (AMD), those with the highest consumption of omega-3 fatty acids were 30 percent less likely to progress to the advanced form of the disease over a 12-year period than those with the lowest omega-3 intake, researchers found."

"A large 10-year study found that half of all fatal heart disease cases and a quarter of all non-fatal cases are linked to being overweight and having a high body mass index (BMI) or large waist. Body mass index and waist circumference are well known risk factors for cardiovascular diseases but the Dutch researchers said their work showed BMI and waist size could actually help predict the risk of dying from or developing heart disease."

"NEW YORK (Reuters Health) - Women who eat greater amounts of plant-based foods and drinks with the naturally occurring flavonoid, apigenin, may have a decreased risk for ovarian cancer, study findings suggest. Apigenin, found in celery, parsley, red wine, tomato sauce, and other plant-based foods may be "particularly beneficial," said Dr. Margaret A. Gates, of Brigham and Women's Hospital and Harvard Medical School, in Boston, Massachusetts. Flavanoids are compounds with antioxidant properties that protect cells against damage by oxygen molecules. In a study that compared flavonoid intake among women with and without ovarian cancer, women reporting the highest apigenin intake had a "borderline significant decrease" in ovarian cancer risk over women reporting the lowest apigenin intake, Gates and her associates report in the International Journal of Cancer."

Anticancer properties of Ganoderma lucidum methanol extracts in vitro and in vivo. Harhaji Trajković LM, Mijatović SA, Maksimović-Ivanić DD, Stojanović ID, Momcilović MB, Tufegdzić SJ, Maksimović VM, Marjanović ZS, Stosić-Grujicić SD. Nutr Cancer. 2009;61(5):696-707. PMID: 19838944 DOI: 10.1080/01635580902898743 Anticancer activities of various extracts of the medicinal mushroom, Ganoderma lucidum, have been widely demonstrated and are mainly associated with the presence of different bioactive polysaccharides and triterpenoids. We have evaluated and compared in vitro and in vivo the antitumor effects of two preparations from Ganoderma lucidum: a methanol extract containing total terpenoids (GLme) and a purified methanol extract containing mainly acidic terpenoids (GLpme). Both extracts inhibited tumor growth of B16 mouse melanoma cells inoculated subcutaneously into syngeneic C57BL/6 mice and reduced viability of B16 cells in vitro, whereby GLme exhibited stronger effect. Furthermore, anticancer activity of GLme was demonstrated for the first time against two other rodent tumor cell lines, L929-mouse fibrosarcoma and C6-rat astrocytoma. The mechanism of antitumor activity of GLme comprised inhibition of cell proliferation and induction of caspase-dependent apoptotic cell death mediated by upregulated p53 and inhibited Bcl-2 expression. Moreover, the antitumor effect of the GLme was associated with intensified production of reactive oxygen species, whereas their neutralization by the antioxidant, N-acetyl cysteine, resulted in partial recovery of cell viability. Thus, our results suggest that GLme might be a good candidate for treatment of diverse forms of cancers.
