Introduction: food photographs are aids used in estimating portion sizes in dietary evaluation. Those designed for the adult population have been shown to be inappropriate for evaluating intake in children. Currently, Argentina does not have food photographs designed for the population of children under 5 years of age.

Objective: To develop and validate a photographic food atlas for children from 1 to 5 years old in Argentina.

Materials and method: an action-research study was carried out, divided into two stages. In the first, a photographic food atlas was develop and in the second, the instrument was validated through an exploratory cross-sectional observational study with a quali-quantitative approach carried out in two educational establishments in the city of La Plata. The photographic atlas has 77 series of food photographs. The validation was carried out through visual perception sessions in real time. An assessment of the visual characteristics and the content of the atlas was carried out by Nutrition Graduates through a semi-structured survey.

Results: 168 voluntary parents or caregivers participated, 102 women and 66 men. The total number of portion size estimates was 2,856, of which 65.5% were correct. Foods estimated to be below 60% were semolina, pumpkin puree, grated carrot, apple, zucchini, fruit salad, and rice pudding. The atlas was evaluated by 21 Nutrition Graduates, of which 47.6% thought that its design and content were adequate.

Conclusion: although those series that generated difficulties in estimating the portion should be improved, the photographic food atlas turned out to be a useful tool to estimate the intake in children aged 1 to 5.
