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.
