Draft guidelines for a tool called FRAT: Fortification Rapid Assessment Tool, were prepared by PATH Canada under contract to the Micronutrient Initiative in 1997-1998. This tool provides guidelines for conducting research to determine if a given food, or a few selected foods, would be appropriate vehicles for food fortification, and, if appropriate, for helping to set the fortification levels in these foods. An appropriate vehicle is:

1. one for which fortification with the desired micronutrient(s) is technically feasible,
2. consumed regularly by the target populations, and,
3. preferably, centrally marketed or processed so that only a single or very few fortification points are required.
