Information on long-term dietary intake is often required for nutrition research or program planning, but surveys routinely use short-term assessments such as 24-hour recalls. Methods to reduce the impact of within-person variation in 24-hour recalls typically require extensive training and skill. Developed to facilitate analysis and modeling of dietary data to inform nutrition research, programs, and policy, the Simulating Intake of Micronutrients for Policy Learning and Engagement (SIMPLE) macro is a dietary software tool to increase the accessibility of 24-hour analysis. The authors explain the theory behind the tool and provide examples of potential applications.
