Information on Emergency Recuperation Ration

Would greatly appreciate advice, lessons learned, and other direction on finding info on emergency recuperation ration. Specifically, this is a two-week ration of specialized nutritional commodities for displaced populations.

A Pubmed and Google Scholar search yielded very little in terms of implementation of this ration, whether it is standardized between country/emergency responses, and what the findings show that the ration should primarily be used for (preventative or treatment approaches).

Looking forward to thoughts and insights.
