Innovations Report, a European forum for science, industry and business professionals, reports on a two-year study conducted by the Institute of Food Research, which examined the eating habits of students at a British school. In order to record what each student was eating, researchers went through data generated by smart-card technology, which is used by students to pay for their meals. The senior nutritionist on the study said that smart-card technology had “demonstrated the ability of the system to identify individuals who persistently choose highly inappropriate meals.”
