In a recent document (2011), USAID, in collaboration with the UN Global Nutrition Cluster, UNHCR , WFP and other organizations, suggest which type of programme and food commodities are more adequate.
However, it was concluded that there is no one food product that can meet every kind of programming goal, and no one programming approach that fits all needs.
The same panel developed decision trees and few flow charts to help policy makers and donors in taking more informed decisions about programmes and choice of food-products.
The original program guidance is available here, whereas another version of the same, visible above, was adjusted in one chapter of my PhD thesis.
