myfood24 is a fully automated online 24-h dietary assessment system with the flexibility to be self- or interviewer-administered as required and to be used as either a 24-h dietary recall or a prospective food diary. It has been developed for use among British adolescents and adults.

The myfood24 food composition dataset has been created by mapping ~ 50,000 commercial ‘back of pack’ food label nutrient data from branded items to generic data from the McCance and Widdowson's ‘The Composition of Foods’ tables, providing over 100 macronutrient and micronutrient attributes. 

This integrated dataset is accessed via an easy to use online application. Participants are able to record their dietary intake by selecting foods and portion sizes and adding them to their food diary.
