Obesity is generally linked to poor eating habits and the availability of tasty, high-calorie foods. However, a new study led by researchers from the Magnetic Resonance Imaging Research Unit in the Department of Radiology at Hospital del Mar and the Barcelona Institute for Global Health (ISGlobal), a center supported by the “la Caixa” Foundation, has found that more elements are involved. Thanks to images obtained by functional magnetic resonance imaging, the researchers found that certain parts of the brains of obese children show alterations with respect to normal-weight or overweight children of the same age. The study findings were published in the journal Cerebral Cortex.
