Tool Information: 24h Recall (Food Photography)

Full Nutrient, Food Groups Retrospective 1 day 24 Hour Recall No


This tool uses digital food photographs and a photo atlas alongside a 24hr recall to improving recall accuracy. Participants were given a digital camera to photograph their meals before and after consumption. The photo atlas contained 78 commonly consumed foods depicted in 3 to 7 different portion sizes. The tool was developed to more accurately assess dietary intake in rural populations reducing the burden of the participants and taking into consideration factors such as literacy level, network and electricity. The tool was validated in 2012, against the food weighed record method and it was successfully used to assess the diet of patients with leishmaniasis and children in rural areas.

Special Considerations

Participants were given a digital camera and table mat marked with 1.5cm grids to match the photo atlas background. Photos included in the atlas were commonly consumed in that area. The 24-h recall was conducted by trained dietitians using the photo atlas and the digital photographs for portion size estimation.
