Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The purpose of this study is to develop a method that uses photography to accurately calculate the types and amounts of nutrients in meals that are consumed by healthy participants, thereby replacing the use of electronic food records. Researchers expect about 100 healthy individuals at UC Davis and around the U.S. will join to participate in this research. Participation in this study will involve taking pictures of every meal and snack the individual consumes using a smartphone for 3 days (2 weekdays, 1 weekend day) and uploading the images to a mobile phone application called Bitesnap. In addition, the participant will be asked to complete online food records on the same days using the Automated Self-Administered 24-hour Dietary Assessment Tool (ASA24-2020). Each participant will have 4 weeks to complete the study. The study website can be viewed here: https://snapme.ucdavis.edu/
