While most nutrition experts agree that school lunches should include more whole-grain products, a new study from the University of Minnesota finds that food-service workers lack understanding and the resources to meet that goal. http://www.physorg.com/news163171389.html Medicine & Health Tue, 02 Jun 2009 14:23:44 EST news163171389 The prevalence of overweight in the US population is among the highest in Mexican-American children and adolescents. In a study of 1,030 Hispanic children between the ages of 4 and 19, published in the June 2009 issue of the Journal of the American Dietetic Association, researchers from the Baylor College of Medicine found less than optimal diets in both overweight and non-overweight participants. http://www.physorg.com/news163072301.html Medicine & Health Mon, 01 Jun 2009 10:52:39 EST news163072301 The popular belief that healthy eating starts at home and that parents' dietary choices help children establish their nutritional beliefs and behaviors may need rethinking, according to a study by researchers at the Johns Hopkins Bloomberg School of Public Health. An examination of dietary intakes and patterns among U.S. families found that the resemblance between children's and their parents' eating habits is weak. The results are published in the May 25, 2009, issue of Social Science and Medicine. http://www.physorg.com/news162815348.html Medicine & Health Fri, 29 May 2009 11:29:38 EST news162815348 Scientists in Portugal and France managed to follow the patterns of gene expression in food-poisoning bacteria Listeria monocytogenes (L. monocytogenes) live during infection for the first time. The work about to be published in PLoS Pathogens shows how the bacterial genome shifts to better adapt to infection by activating genes involved in virulence and subversion of the host defences, as well as adaptation to the host conditions. This is the first time that the molecular interactions between L. monocytogenes and its host, as they occur during the different steps of infection, are followed in real time paving the way, not only to the development of new therapies against this potentially lethal bacterium, but also for the study of other pathogen/host interactions. http://www.physorg.com/news162754099.html Biology Thu, 28 May 2009 18:28:56 EST news162754099 There are several risk factors for the development of Alzheimer's disease and vascular dementia. Based on an increasing number of studies linking these risk factors with Vitamin D deficiency, an article in the current issue of the Journal of Alzheimer's Disease (May 2009) by William B. Grant, PhD of the Sunlight, Nutrition, and Health Research Center (SUNARC) suggests that further investigation of possible direct or indirect linkages between Vitamin D and these dementias is needed. http://www.physorg.com/news162562458.html Medicine & Health Tue, 26 May 2009 13:14:53 EST news162562458 Pregnant women with low levels of vitamin D may be more likely to suffer from bacterial vaginosis (BV) - a common vaginal infection that increases a woman's risk for preterm delivery, according to a University of Pittsburgh study. Available online and published in the June issue of the Journal of Nutrition, the study may explain why African-American women, who often lack adequate vitamin D, are three times more likely than white women to develop BV. http://www.physorg.com/news162216931.html Medicine & Health Fri, 22 May 2009 13:16:12 EST news162216931 Nearly 20 years ago, it was discovered that bacteria known as Helicobacter pylori were responsible for stomach ulcers. Since then, antibiotics have become the primary therapy used to combat the H. pylori infection, which affects approximately six percent of the world population and is also a primary cause of stomach cancer. But today the bacteria is growing increasingly resistant to antibiotics. http://www.physorg.com/news161614249.html Medicine & Health Fri, 15 May 2009 13:51:13 EST news161614249 Bacterial vaginosis (BV) is the most common vaginal infection in US women of childbearing age, and is common in pregnant women. BV occurs when the normal balance of bacteria in the vagina is disrupted and replaced by an overgrowth of certain bacteria. Because having BV puts a woman at increased risk for a variety of complications, such as preterm delivery, there is great interest in understanding how it can be prevented. http://www.physorg.com/news161520128.html Medicine & Health Thu, 14 May 2009 11:42:35 EST news161520128 Exercise physiologist Lynne Kammer, from The University of Texas at Austin, led a group of researchers who investigated the post-exercise physiological effects of the foods. Kammer and her team studied 12 trained cyclists, 8 male and 4 female. In contrast to many sports nutrition studies, however, the exercise protocol was designed to reflect a typical exercise session. After a warm-up period, the subjects cycled for two hours at a comfortable work rate, rather than the more frequently seen test-to-exhaustion. http://www.physorg.com/news161512020.html Medicine & Health Thu, 14 May 2009 09:27:24 EST news161512020 The beta-carotene in so-called "Golden Rice" converts to vitamin A in humans, according to researchers at Baylor College of Medicine and Tufts University in an article that appears in the current issue of the American Journal of Clinical Nutrition. http://www.physorg.com/news161441355.html Medicine & Health Wed, 13 May 2009 13:49:48 EST news161441355 A new study by a Ben-Gurion University of the Negev (BGU) researcher reveals a linkage between elderly people's appetite and mortality rates, with those who report impaired appetite more likely to die sooner. http://www.physorg.com/news161365353.html Medicine & Health Tue, 12 May 2009 16:42:50 EST news161365353 A new study has sounded the alarm that the majority of Canadian adults are inactive over their lifespan and don't exercise enough during their leisure time. Published in the International Journal of Behavioral Nutrition and Physical Activity, the study is unique in that it collected information over two decades from the 1981 Canada Fitness Survey, the 1988 Campbell's Survey of Well-Being and from the 2002/4 Physical Activity Longitudinal Study of the Canadian Fitness and Lifestyle Research Institute. http://www.physorg.com/news161349169.html Medicine & Health Tue, 12 May 2009 12:13:21 EST news161349169 Brown University researchers have shown that there is an inexpensive way to help low-income, ethnically diverse people eat better: Send personalized nutrition education materials through the mail. http://www.physorg.com/news161027105.html Medicine & Health Fri, 08 May 2009 18:45:36 EST news161027105 Immigrant populations in Europe face an increased risk of diet-related diseases as they adjust to a 'Western' lifestyle, according to scientists at the University of Leeds. http://www.physorg.com/news160896758.html Medicine & Health Thu, 07 May 2009 06:37:45 EST news160896758 Consumers are five times more likely to identify healthy food when they see colour-coded traffic light nutrition labels than when labels present the information numerically by showing what percentage of the recommended daily nutrient intake each portion provides, new research finds. http://www.physorg.com/news160896492.html Medicine & Health Thu, 07 May 2009 06:29:59 EST news160896492 (PhysOrg.com) -- A new study has found that keeping the diet for type 2 diabetes under control gets a lot of help from including daily amounts of foods with the right kind of fats such as walnuts. http://www.physorg.com/news160765693.html Medicine & Health Tue, 05 May 2009 18:09:03 EST news160765693 Researchers from LIFE - Faculty of Life Sciences at University of Copenhagen are working on a promising research project that seems to indicate that probiotics have a slimming effect. http://www.physorg.com/news160725306.html Medicine & Health Tue, 05 May 2009 06:55:52 EST news160725306 Possible anti-obesity effects of white tea have been demonstrated in a series of experiments on human fat cells (adipocytes).

This slower pattern of growth in the first year of life is possibly one reason why breast-fed babies are less likely to become overweight children later on. http://www.physorg.com/news159699110.html Medicine & Health Thu, 23 Apr 2009 09:52:25 EST news159699110 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 The good nutrition news is that children in poor, rural parts of the Lower Mississippi Delta are a lot more willing to try fresh fruits and vegetables than generally believed, even by their parents or the kids themselves. The bad news is that such foods are often in short supply in an area where gas stations and convenience stores are the closest places to buy food and where growing family gardens has given way to long work commutes by parents - and that the situation is growing worse with a worsening economy. http://www.physorg.com/news159371324.html Medicine & Health Sun, 19 Apr 2009 14:49:12 EST news159371324 The benefits of physical activity and a balanced diet are well documented and form the basis of many public health recommendations. This is because each of these factors can independently influence risks for many chronic diseases such as obesity, type 2 diabetes, and some forms of cancer. http://www.physorg.com/news158944077.html Medicine & Health Tue, 14 Apr 2009 16:08:18 EST news158944077 The new science of epigenetics explains how genes can be modified by the environment, and a prime result of epigenetic inquiry has just been published online in The FASEB Journal: You are what your mother did not eat during pregnancy. In the research report, scientists from the University of Utah show that rat fetuses receiving poor nutrition in the womb become genetically primed to be born into an environment lacking proper nutrition. As a result of this genetic adaptation, the rats were likely to grow to smaller sizes than their normal counterparts. At the same time, they were also at higher risk for a host of health problems throughout their lives, such as diabetes, growth retardation, cardiovascular disease, obesity, and neurodevelopmental delays, among others. Although the study involved rats, the genes and cellular mechanisms involved are the same as those in humans. http://www.physorg.com/news158856122.html Medicine & Health Mon, 13 Apr 2009 15:43:43 EST news158856122 (AP) -- Food stamps and child nutrition programs are expected to cost up to $900 million more this year because of increased ethanol use. http://www.physorg.com/news158569963.html Other Sciences Fri, 10 Apr 2009 08:13:05 EST news158569963 For the past several decades, evidence has shown that greater dietary intake of the B-vitamin, folate, offers protection against the development of certain common cancers and reduces neural tube defects in newborns, opening new avenues for public health interventions that have a great impact on health. However, folate's central role as an essential factor in DNA synthesis also means that abundant availability of the vitamin can enhance the development of pre-cancerous and cancerous tumors. http://www.physorg.com/news157806407.html Medicine & Health Wed, 01 Apr 2009 12:07:25 EST news157806407 Cancer and its therapies, including chemotherapy and radiotherapy, may directly alter and damage taste and odor perception, possibly leading to patient malnutrition, and in severe cases, significant morbidity, according to a Virginia Tech - Wake Forest University Comprehensive Cancer Center compilation of various existing studies.

However, since PEG is based on a surgical technique and is mainly performed in elderly individuals with poor general conditions, the frequency of adverse events is higher compared to other methods of nutrition. Even when PEG is successful, patients often encounter enteral nutrition problems after surgery. Although the knowledge of the predictors of post-operative enteral nutrition problems may provide useful information, there are no studies that have specifically examined such predictors. http://www.physorg.com/news157128657.html Medicine & Health Tue, 24 Mar 2009 15:51:22 EST news157128657 Almost half of all patients with cancer of the voice box (larynx) who receive radiotherapy treatment will experience malnutrition, according to new data presented at the European Society for Medical Oncology's Symposium on Cancer and Nutrition (Zurich, 20-21 March 2009). http://www.physorg.com/news156779040.html Medicine & Health Fri, 20 Mar 2009 14:44:28 EST news156779040 Boosting calcium consumption spurs weight loss, according to a study published in the most recent issue of the British Journal of Nutrition, but only in people whose diets are calcium deficient. http://www.physorg.com/news156076519.html Medicine & Health Thu, 12 Mar 2009 11:35:53 EST news156076519 Low levels of vitamin D were associated with an increased risk of high blood pressure, high blood sugar and metabolic syndrome in teenagers, researchers reported at the American Heart Association's 49th Annual Conference on Cardiovascular Disease Epidemiology and Prevention. http://www.physorg.com/news156000592.html Medicine & Health Wed, 11 Mar 2009 14:30:26 EST news156000592
