Today’s Headlines: Fiber, Creativity and ADHD

Dietary fiber may help heart attack survivors live longer: Heart attack survivors may want to load up on fiber.  A new study shows that people who ate the most fiber after surviving a heart attack had a 25% reduced risk of dying over the next nine years, compared to people who didn’t eat much fiber. “Increasing fiber intake by 10g per day was associated with a 15 percent lower risk of dying over the same period.” In the past, a high-fiber diet has been linked to a lower risk of coronary heart disease. Though the researchers looked at three kinds of fiber – cereal, fruit and vegetable – they found that “cereal was the only type of fiber strongly associated with an increased chance of long-term survival.” (Fox News)

Want to Be More Creative? Take a Walk: Here’s another reason to get active. “A brief stroll, even around your office, can significantly increase creativity, according to a handy new study.” Researchers at Stanford University asked students to sit and complete creative tasks like having to come up with alternative uses for everyday objects. Then, they asked participants to walk on a treadmill that faced a blank wall. The students repeated the creativity tasks while they were moving. “For almost every student, creativity increased substantially when they walked. Most were able to generate about 60 percent more uses for an object.” The boost in creativity also lasted when researchers subsequently asked the students to perform the tasks after walking, instead of during the walk.

MRI technique could provide accurate and early ADHD diagnosis: “Using resting-state functional magnetic resonance imaging, researchers have uncovered disrupted connections between different brain areas in children and adolescents with attention deficit hyperactivity disorder.” The research team studied 33 boys with ADHD and 32 without. “The team found that the boys with ADHD had altered structure and function in certain areas of the brain, such as the orbitofrontal cortex – an area involved in strategic planning.” The researchers say that in the future, MRIs be used to provide faster, more accurate diagnoses of ADHD, a neurobehavioral disorder that leads to concentration problems and hyperactivity. However, further study is needed to determine what patterns in the brain correspond to ADHD. (Medical News Today)
