Maintaining a Mediterranean diet with your phone
Researchers at the ARTORG Center in collaboration with Oviva and with the Epidemiology, Biostatistics and Prevention Institute (EBPI), University of Zurich, have demonstrated that an AI system on a smartphone can effectively track whether a person is adhering to a Mediterranean diet (MD). MD can decrease the risk of non-communicable disease and prevent overweight and obesity. The feasibility study of the system was just published in Nature Scientific Reports.
Adherence to Mediterranean diet can be a powerful preventive tool against a variety of diet-related diseases. To date, this adherence is evaluated by manuel user diaries and expert dietitian assessments. The ARTORG Center has now developed and evaluated a new Artificial Intelligence-powered system that recognizes the food and drink items from a single meal photo and estimates their respective serving size. The system was integrated into a smartphone application that automatically calculates MD adherence score and outputs a weekly feedback report in collaboration with Oviva. System performance was first tested against expert dietitian evaluations of MD adherence scores.
A subsequent feasibility study with 24 participants revealed an image recognition of 61.8% mean average precision for testing and 57.3% for the study images. Participant feedback on usability was very positive.
