The Oxford WebQ is a validated web-based 24 hour dietary assessment tool developed for repeated administration in large prospective studies. It is a self-administered low-cost method for measuring dietary intake, and in our evaluation it took a median of 12·5 minutes to complete. Nutrients are estimated automatically.
