Overconsumption of fatty, sugary foods leads to changes in brain receptors, according to new animal research at Johns Hopkins University School of Medicine. The new research results are being presented at the 2009 annual meeting of the Society for the Study of Ingestive Behavior (SSIB), the foremost society for research into all aspects of eating and drinking behavior. The results have implications for understanding bulimia and other binge eating disorders. http://www.physorg.com/news167936267.html Medicine & Health Tue, 28 Jul 2009 01:30:01 EST news167936267 A glass of wine here, a nightcap there - new research out of Wake Forest University School of Medicine suggests that moderate alcohol intake offers long-term cognitive protection and reduces the risk of dementia in older adults. http://www.physorg.com/news166703798.html Medicine & Health Mon, 13 Jul 2009 11:37:01 EST news166703798 Though discoveries about Alzheimer's disease risk factors are often in the news, adults do not know about the relationship between Alzheimer's disease risk and heart health, nor that physical activity can be protective against dementia, according to new research reported today at the Alzheimer's Association 2009 International Conference on Alzheimer's Disease (ICAD 2009) in Vienna. http://www.physorg.com/news166690799.html Medicine & Health Mon, 13 Jul 2009 08:30:01 EST news166690799 And when she doesn't gain a pound -- ever -- there's only one thing to blame: her metabolism. http://www.physorg.com/news165691681.html Medicine & Health Wed, 01 Jul 2009 20:30:01 EST news165691681 Fifty years ago Friday, President Dwight Eisenhower and Britain's Queen Elizabeth II walked down a red carpet, climbed aboard a "floating palace" of a yacht named Britannia and ceremoniously sailed through the St. Lambert lock near Montreal to hail the opening of the St. Lawrence Seaway. http://www.physorg.com/news165255219.html Space & Earth Fri, 26 Jun 2009 18:20:02 EST news165255219 Some food groups in the Mediterranean diet are more important than others in promoting health and longer life according to new research published on bmj.com today. http://www.physorg.com/news165005282.html Medicine & Health Tue, 23 Jun 2009 19:48:32 EST news165005282 Calcium and dairy products play major roles in health maintenance and the prevention of chronic disease. Because peak bone mass is not achieved until the third decade of life, it is particularly important for young adults to consume adequate amounts of calcium, protein and vitamin D found in dairy products to support health and prevent osteoporosis later in life. In a study in the July/August issue of the Journal of Nutrition Education and Behavior, researchers report that young people actually reduce their intake of calcium and dairy products as they enter their twenties. http://www.physorg.com/news164257974.html Medicine & Health Mon, 15 Jun 2009 05:20:01 EST news164257974 Researchers at Imperial College London have identified a new appetite suppressant for promoting weight loss that they say works in rodents and may one day be used to develop an effective anti-obesity treatment. http://www.physorg.com/news163850449.html Medicine & Health Wed, 10 Jun 2009 11:50:01 EST news163850449 A new review published in the Journal of Human Nutrition and Dietetics assessed whether certain modifications in diet have a beneficial effect on the prevention of prostate cancer.

Paradoxically, researchers have suggested that small exposure to oxidative conditions may actually offer protection from acute doses. Now, scientists at the University of California, San Diego, have discovered the gene responsible for this effect. Their study, published in PLoS Genetics on May 29, explains the underlying mechanism of the process that prevents cellular damage by reactive oxygen species (ROS). http://www.physorg.com/news162797155.html Medicine & Health Fri, 29 May 2009 06:26:23 EST news162797155 For 20 years, Maurie Ange of El Cerrito, Calif., suffered from chronic belly aches.

The study followed more than 2,000 seniors who were current smokers, past smokers and had never smoked. All three groups were compared to show a link between smoking and the speed at which participants walked. After five years, it was discovered that smokers showed a significantly slower pace in their gait than those who had previously smoked. These study results suggest that even at an older age, changing bad habits such as smoking can positively impact a senior's health later in life. http://www.physorg.com/news159712917.html Medicine & Health Thu, 23 Apr 2009 13:42:26 EST news159712917 Liwei Chen, MD, PhD, Assistant Professor of Epidemiology at the LSU Health Sciences Center New Orleans School of Public Health, is the lead author of a research paper showing that weight gain and obesity are more linked to an increase in liquid calories, particularly sugar-sweetened beverages, than calories from solid food. To our knowledge, this is the first study to document the relative effects of calories from liquids compared with those of calories from solid food on weight loss in adults over an extended period. The study is published in the May 1, 2009 issue of the American Journal of Clinical Nutrition. http://www.physorg.com/news159632501.html Medicine & Health Wed, 22 Apr 2009 15:22:09 EST news159632501 Meat cooked at high temperatures to the point of burning and charring may increase the risk of pancreatic cancer, according to data presented at the American Association for Cancer Research 100th Annual Meeting 2009. http://www.physorg.com/news159559671.html Medicine & Health Tue, 21 Apr 2009 19:08:35 EST news159559671 However, the downside is that up a quarter of people with alcohol-related cirrhosis die before they get the chance to stop drinking.
