Our technical assistance tools are now available in beta mode, for early adopters to test and provide feedback. The toolkit provides templates for calculating diet costs from the typical food price datasets collected by national statistical organizations and market information services. Components of the toolkit are designed to be readily customized for integration into your own organization or project’s data analysis protocols, to automate the selection of least-cost items in each food group needed to calculate the Cost of a Healthy Diet.
For other aspects of our work, please scroll down to see replication files with code & data for previously published studies, with the code and data to reproduce those results.
This beta release is version 3.0 of our toolkit to compute least-cost diets from local price observations, designed for early adopters to test, use and modify with their own price data. We appreciate your feedback!
The beta version of our technical assistance toolkit is packaged as a single large downloadable folder (>200mb) with the components listed below.
