Locally developed food-based recommendations (FBRs) help promote appropriate complementary feeding that contributes to reducing stunting among children under 5. A tool used to develop FBRs, Optifood, usually relies on primary data collection involving 24-hour dietary recalls and food frequency questionnaires, the use of which requires considerable time and resources. FANTA conducted a study on the feasibility of developing FBRs with Optifood in Guatemala by analyzing secondary data from a Household Consumption and Expenditure Survey (HCES). The study compared Optifood inputs and outputs derived from the HCES data with inputs and outputs using primary data from a 2012 FANTA Optifood study in Guatemala. The results show that HCES data can serve as a proxy for primary 24-hour recall and food frequency data in Optifood for the development of FBRs. All FBRs need to be tested at the community level before implementation.
