Dietary Diversity as a Household Food Security Indicator (2002)Dietary diversity, defined as the number of unique foods consumed over a given period of time, is a useful approach for measuring food security and monitoring changes, particularly when resources for such measurements are scarce. FANTA conducted a series of activities aimed at developing user-friendly, cost-effective approaches to measuring changes in dietary quantity and quality and feeding behaviors at both the household and individual levels. For one such activity, FANTA’s subcontractor, the International Food Policy Research Institute, analyzed household data sets from 10 countries to assess whether dietary diversity could be used as a tool in evaluating the efficacy of food security interventions. The study validated the dietary diversity indicator as a measure of access to food (per capita expenditures) and as a measure of consumption (caloric availability at the household level).
