Purpose of programme

If the purpose is restoration of the nutrients lost through milling, only those nutrients would be included - and to the levels that would provide the nutrients up to the natural levels in wheat and maize.

If the purpose is to make up for all or part of dietary deficiencies in the target population, the average consumption levels in the population must be known. The shortfall to be covered may vary, depending on the dietary requirement values used (e.g the US Institute of Medicine Recommended Dietary Allowances (RDA) or the Estimated Average Requirement determined by FAO/WHO, or national values.
