Exercise has numerous beneficial effects on brain health and cognition, review suggests
Exercise has numerous beneficial effects on brain health and cognition, review suggests: "
"
It's no secret that exercise has numerous beneficial effects on the body. However, a bevy of recent research suggests that these positive effects also extend to the brain, influencing cognition. In a new review article highlighting the results of more than a hundred recent human and animal studies on this topic, Michelle W. Voss, of the University of Illinois at Urbana-Champaign, and her colleagues show that both aerobic exercise and strength training play a vital role in maintaining brain and cognitive health throughout life. However, they also suggest that many unanswered questions remain in the field of exercise neuroscience—including how various aspects of exercise influence brain physiology and function and how human and animal studies relate to each other—and issue the call for further research to fill in these gaps.

Children eating more, and more frequently outside the home: "
"
As childhood obesity rises and the American diet shifts towards increasing consumption of foods eaten or prepared outside of the home, concerns about the nutritional quality and the total consumption of such foods are also increasing. 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.

Study: Doctors differ in how best to care for America's 12 million cancer survivors: "
"
There are major differences between oncologists and primary care physicians regarding knowledge, attitudes, and practices required to care for American's 12 million cancer survivors. That is the key finding of the first nationally representative survey of doctors that reveals how these differences pose significant barriers to effective communication and coordination of care following initial cancer treatment.
