Even though the obesity epidemic is getting out of control, dietary research still heavily relies on self-reported survey data, which is often incorrect. One option to get around this is to have people eat in a lab, but that would likely interfere with their natural eating habits and produce worthless data. So, as another option, these researchers have developed the “Automated Ingestion Detection” (AID) technology to track what patients are eating. It works by wearing a microphone around your neck that records swallowing sounds, which doctors then use to record how much is going down your gullet. Although the authors only discuss how this would be used for dietary research, there are other, uh… “more adult” questions that could be readily answered by this handy device.
