As children transition from preschool-age to school-age, they may develop eating habits and leisure-time patterns that may not meet current recommendations and may contribute to childhood obesity. In a study published in the January/February 2009 issue of the Journal of Nutrition Education and Behavior, researchers report that parents perceived that their pre-school children (2 to 5 years) had relatively good eating habits and physical activity levels, but that parents of school-aged children (6 to 12 years) felt their children had less healthful diets and leisure-time activities. http://www.physorg.com/news150695788.html Medicine & Health Fri, 09 Jan 2009 03:56:28 EST news150695788 While the U.S. Food and Drug Administration Drug has quickened review and approval of new medicines, the complex nature of diseases for which new therapeutics are being developed has resulted in longer clinical development times, according to the Tufts Center for the Study of Drug Development. http://www.physorg.com/news150647377.html Medicine & Health Thu, 08 Jan 2009 14:29:37 EST news150647377 Rapidly warming climate is likely to seriously alter crop yields in the tropics and subtropics by the end of this century and, without adaptation, will leave half the world's population facing serious food shortages, new research shows. http://www.physorg.com/news150646556.html Other Sciences Thu, 08 Jan 2009 14:15:56 EST news150646556 Aquaculture production of seafood will probably remain the most rapidly increasing food production system worldwide through 2025, according to an assessment published in the January 2009 issue of BioScience. The assessment, by James S. Diana of the University of Michigan at Ann Arbor, notes that despite well-publicized concerns about some harmful effects of aquaculture, the technique may, when practiced well, be no more damaging to biodiversity than other food production systems. Moreover, it may be the only way to supply growing demand for seafood as the human population increases. http://www.physorg.com/news150115484.html Biology Fri, 02 Jan 2009 10:44:44 EST news150115484 Michigan State University researchers are helping a technology startup company improve the safety of leafy greens and other foods as more consumers seek to eat fresh and healthy. http://www.physorg.com/news149938982.html Biology Wed, 31 Dec 2008 09:43:02 EST news149938982 Some supermarkets, gourmet shops and bakeries routinely sell mislabeled products that pose a danger to children with food allergies, according to Chicago Tribune testing and a comprehensive check of grocery aisles.
