Obese children more vulnerable to food advertising

Amanda S. Bruce, PhD, and colleagues from the University of Missouri-Kansas City and the University of Kansas Medical Center assessed 10 healthy weight and 10 obese children, ages 10-14 years, using both self-reported measures of self-control and functional magnetic resonance imaging, which uses blood flow as a measure of brain activity. Dr. Bruce states, “We were interested in how brain responses to food logos would differ between obese and healthy weight children.” The children were shown 60 food logos and 60 nonfood logos, and functional magnetic resonance imaging scans indicated which sections of the brain reacted to the familiar logos being shown.
