It also looked at genetic factors and mechanisms by which resveratrol might be absorbed by the body and its possible effect on longevity of life. The authors report that pure resveratrol intake was associated with higher lung volumes and that white wine intake (but not red wine intake) and was associated with lower risk of airway obstruction. They report that the genetic factors studied did not relate to the associations found. http://medicalxpress.com/news/2012-03-moderate-wine-consumption-lung-function.html Health Thu, 08 Mar 2012 10:49:48 EST news250426178 A compound in citrus fruits may reduce your stroke risk, according to research reported in Stroke: Journal of the American Heart Association. http://medicalxpress.com/news/2012-02-citrus-fruit-women.html Cardiology Thu, 23 Feb 2012 16:00:01 EST news249226233 (Medical Xpress) -- Being involved in a healthy, loving relationship is good for the heart, says Vanderbilt Heart and Vascular Institute cardiologist Julie Damp, M.D. “There are a couple of different theories behind why that might be,” Damp said. http://medicalxpress.com/news/2012-02-chocolate-good-heart-cardiologist.html Health Tue, 14 Feb 2012 06:20:01 EST news248420078 A well-conducted experimental study in mice has provided potentially important new insights into the association of the intake of resveratrol and like compounds with health benefits. Resveratrol is a constituent of red wine and other vegetable products, and is being evaluated in high-doses as a pharmaceutical. The biologic mechanisms demonstrated in this study could provide key new approaches for the prevention or treatment of a number of chronic diseases in humans, especially those related to vascular and metabolic diseases and to the risk of mortality. http://medicalxpress.com/news/2012-02-potentially-important-mechanisms-anti-aging-effects.html Medical research Thu, 09 Feb 2012 13:10:42 EST news248015431 Forget the oysters and the champagne this Valentine’s Day.

The authors present evidence that resveratrol does not directly activate sirtuin 1, a protein associated with aging. Rather, the authors found that resveratrol inhibits certain types of proteins known as phosphodiesterases (PDEs), enzymes that help regulate cell energy. http://medicalxpress.com/news/2012-02-uncovers-probable-mechanism-underlying-resveratrol.html Medical research Thu, 02 Feb 2012 12:00:10 EST news247402648 A meta-analysis done by the Centre for Addiction and Mental Health (CAMH) into the relationship between alcohol consumption and heart disease provides new insight into the long-held belief that drinking a glass of red wine a day can help protect against heart disease. http://medicalxpress.com/news/2012-01-alcohol-heart-friend-foe.html Health Mon, 30 Jan 2012 11:23:43 EST news247145009 Aromatase inhibitors (AIs) prevent the conversion of androgens to estrogens, and could play a role in the development of breast cancer. This study of 36 pre-menopausal women consisted of a cross-over intervention trial to determine if there were differences between red wine and white wine in their effects on AIs. Subjects sequentially consumed eight ounces of red wine, followed by white wine (or vice versa), each beverage for a one-month period. The investigators concluded that red wine, but not white wine, was associated with significant effects on some indices of estrogen metabolism; free testosterone and luteinizing hormone were increased, but no significant differences were noted in estrogen levels. http://medicalxpress.com/news/2012-01-comparison-effects-red-wine-white.html Cancer Thu, 19 Jan 2012 10:37:12 EST news246191817 Observational epidemiologic studies relating wine and alcohol to health all suffer from the fact that they, of necessity, compare people who prefer certain beverages, but not the beverages themselves. While there have been many intervention trials in animals, randomized trials in humans are less common. Randomized crossover trials, in which each subject receives all interventions in sequence, can be especially important as they tend to avoid baseline differences among subjects and can detect effects of different interventions with smaller numbers of subjects. http://medicalxpress.com/news/2012-01-alcohol-polyphenols-red-wine-decreases.html Cardiology Tue, 17 Jan 2012 10:19:06 EST news246016974 A University of Connecticut researcher known for his work on red wine's benefits to cardiovascular health falsified his data in more than 100 instances, university officials said Wednesday. http://medicalxpress.com/news/2012-01-red-wine-accused-falsifying.html Other Wed, 11 Jan 2012 16:39:42 EST news245522365 Drinking red wine in moderation may reduce one of the risk factors for breast cancer, providing a natural weapon to combat a major cause of death among U.S. women, new research from Cedars-Sinai Medical Center shows. http://medicalxpress.com/news/2012-01-moderate-red-wine-women-breast.html Addiction Fri, 06 Jan 2012 09:47:48 EST news245065660 When obese men take a relatively small dose of resveratrol in purified form every day for a month, their metabolisms change for the better.

A new research report appearing in the October 2011 issue of The FASEB Journal shows that resveratrol, the "healthy" ingredient in red wine, stops breast cancer cells from growing by blocking the growth effects of estrogen. This discovery, made by a team of American and Italian scientists, suggests for the first time that resveratrol is able to counteract the malignant progression since it inhibits the proliferation of hormone resistant breast cancer cells. This has important implications for the treatment of women with breast cancer whose tumors eventually develop resistance to hormonal therapy. http://medicalxpress.com/news/2011-09-red-wine-ingredient-resveratrol-breast.html Cancer Thu, 29 Sep 2011 10:17:17 EST news236510225 Eating a diet rich in spices, like turmeric and cinnamon, reduces the body's negative responses to eating high-fat meals, according to Penn State researchers. http://medicalxpress.com/news/2011-08-antioxidant-spices-negative-effects-high-fat.html Health Wed, 10 Aug 2011 10:22:01 EST news232190509 Few studies have examined the acute effects of alcohol on myocardial or heart function. While moderate-to-high blood concentrations of alcohol acutely impair conventional echocardiographic measures of left ventricular (LV) performance, the effects of low concentrations are unclear. An examination of the acute effects of low blood concentrations of alcohol on the left and right ventricles, which collectively pump blood to the entire body, has found that low doses of alcohol can have very different effects on LV and right ventricular (RV) function. http://medicalxpress.com/news/2011-07-amounts-alcohol-effects-left-ventricles.html Health Fri, 15 Jul 2011 17:40:01 EST news229967256 As strange as it sounds, a new research study published in the FASEB Journal, suggests that the "healthy" ingredient in red wine, resveratrol, may prevent the negative effects that spaceflight and sedentary lifestyles have on people. The report describes experiments in rats that simulated the weightlessness of spaceflight, during which the group fed resveratrol did not develop insulin resistance or a loss of bone mineral density, as did those who were not fed resveratrol. http://medicalxpress.com/news/2011-06-red-wine-bottle.html Health Thu, 30 Jun 2011 13:31:08 EST news228659436 A recent study from scientists at the Salk Institute for Biological Studies suggests that a strawberry a day (or more accurately, 37 of them) could keep not just one doctor away, but an entire fleet of them, including the neurologist, the endocrinologist, and maybe even the oncologist. http://medicalxpress.com/news/2011-06-flavonoids-two-fisted-assault-diabetes-nervous.html Medical research Mon, 27 Jun 2011 17:00:04 EST news228394928 UT Southwestern Medical Center researchers are engaging the help of professional boxers and trainers to study whether a component in red wine and grapes could help reduce the short- and long-term effects of concussions. http://medicalxpress.com/news/2011-05-red-wine-compound-concussions-pro.html Health Thu, 26 May 2011 03:49:08 EST news225600526
