This according to a new study from Karolinska Institutet published in the scientific journal Epidemiology.

The project, funded by the Austrian Science Fund (FWF), will complete the current state of research on personality effects from computer games, which has previously been dominated by studies of negative consequences.

According to a study conducted at the University of North Carolina at Chapel Hill and published in the August 2011 issue of the Journal of the American Dietetic Association, eating location and food source significantly impact daily energy intake for children. Foods prepared away from home, including fast food eaten at home and store-prepared food eaten away from home, are fueling the increase in total calorie intake. http://medicalxpress.com/news/2011-07-children-frequently-home.html Health Mon, 25 Jul 2011 02:42:21 EST news230780519
