Study of Environmental Enteropathy and Malnutrition in Pakistan (SEEM) is an ongoing,  longitudinal birth cohort study, aimed to understand the pathophysiology of Environmental Enteropathy and associated biomarkers in children under 2 years of age in rural district of Matiari. We have enrolled 400 children(350 acute malnourished and 50 well-nourished children).we are collecting 24 hours’ food recall through a specialized structured instrument designed to collect all food items consumed in last 24 hours by the enrolled children for the quantitative estimates of the non-breast milk food intake. We have to collect information on portion size consumed by child, any left overs and have to weigh the food items.  Challenges which we are facing during data collection are that mothers are usually not available at home (due to their field work) and they are the best respondent for this type of data. If child has eaten with other siblings in one plate, then we have to probe the mother to estimate the actual amount of food taken e.g. numbers of bites subject ate and size of the bites. In some instances. If we find new recipe, which is not mentioned in our coding list, we have to cook such recipes in our office kitchen to identify the caloric value of the food items. After field data collection, data is converted into quantitative form for data analysis. For this, we have to work in the office for several hours to search for the codes and to assign new codes for new food items
