Imputing Nutrient Intake from Foods Prepared and Consumed Away from Home and Other Composite Foods

Publisher: IFPRI

Twenty-four-hour recall and observed-weighed food record surveys are generally regarded as the gold standard of food consumption surveys, but they are expensive, conducted infrequently, and not available in most countries. As a result, public health nutritionists and food security analysts and policymakers have increasingly turned to alternative data sources, including that already being collected in household consumption and expenditure surveys (HCES). HCESs are nationally representative, multipurpose surveys that are routinely conducted in more than 120 countries. While they are readily available, using them to estimate food consumption is plagued by several data limitations, perhaps foremost among which is how data on consumption of food prepared away from home (FAFH) and composite foods (CF) are collected. Generally, no information is provided about the quantity FAFH or about the ingredients used to make many CF resulting in underestimation of food consumption and nutrient intakes, and overestimation of the prevalence of inadequate nutrient intake, including food insecurity, and the size of the nutrient intake gap.
