Tool Information: Remote Food Photography Method (RFPM)

Full Nutrient Prospective 6 days Food Diary Estimated No


This tool uses Smartphones to capture images of food selection and plate waste and relies on the validated digital photography method. The images are sent to a server in near real-time for food intake estimation by comparing the images with food images of known portion sizes. Prompts are sent to the Smartphones to remind participants to capture food images. This tool was designed to measure energy and nutrient intake of people in their natural environment. The tool was subsequently validated in 2012.
