Assessment of Dietary Intake Using Food Photography and Video Recording in Free-Living Young Adults: A Comparative Study.

Background: Conventional methods of dietary assessment are prone to recall bias and place burden on participants.

Objective: Our aim was to compare the performance of image-based dietary assessment (IBDA), including food photography (FP) and video recording (VR), with the criterion of weighed food records (WFR).

Design: In this comparative study, participants captured meals using FP and VR before and after consumption, over 2 days.
