Nutrition, Activity Improve Students Brain Function

Just 20 minutes per day of exercise improves students' brain activity, according to neurological research. A new report issued by the GENYOUth Foundation, a partnership between the National Dairy Council (NDC) and the National Football League (NFL) highlights the effects of healthy
nutrition couples with physical activity on students' learning potential.

The report, “The Wellness Impact: Enhancing Academic Success Through Healthy School Environments," collated the results of numerous studies, including brain imaging research showing the brains of aerobically fit children may exhibit superior executive-function control. In addition, school breakfast programs contribute to the quality of food children eat and highlight the correlation between diet quality and academic performance.

A recent survey cited in the report found 62% of students did not eat breakfast on all seven days before the survey, and 13% of students never ate breakfast during that time. In fact, more than half of all teens do not eat breakfast each day. Also, nearly three-fourths of high school youth are not physically active for 60 minutes even days a week. Early research on fasting and cognition found that transient hunger in well-nourished school children negatively affected their performance on given tests.

Students who eat breakfast have higher consumption of key nutrients than breakfast skippers and those who skip breakfast do not make up for those missed nutrients from other meals.

One reason for the importance of school breakfast programs, says the report is food insecurity, which affected approximately 16.6 million children in 2011, or 22.4% of the nation’s children who lived in food insecure homes.
Recent controlled studies involving brain imaging are casting new light on the effects of exercise and obesity on cognition, providing visual evidence of the neurophysiological impact of physical activity or lack thereof, on children. Obesity is linked to adverse cognitive performance in school-aged children and teens. In older adults, obesity is actually found to change brain structure.

A related study by the Trust for America’s Health predicts that more than half of Americans in 39 states could be obese by 2030, with a likely resulting rise in obesity-related disease and healthcare costs.
