This commentary summarizes the responses of 5 leading public health nutrition practitioners who were invited to review and comment on the articles, with a particular focus on,
- the gaps in important information available to micronutrient program decision makers that would be filled by the suite of models we have developed, with particular attention paid to the economic optimization model,
- the major challenges we can expect to face as we begin to use the models to engage with decision makers in designing and managing micronutrient intervention programs, and
- changes to any of the models that would make them more relevant and useful.
The commentary consolidates these points of view to point out areas of agreement and areas of differing opinions.
