A consultation on Double Fortified Salt (DFS): A call for authors

IGN is seeking individuals or institutions interested in taking the lead in the development of background papers for a global consultation on Double Fortified Salt (DFS).

Several million people globally suffer from sub-optimal intake of vitamins and minerals. Fortifying staple foods and condiments with essential micronutrients is proven to be a cost-effective and sustainable intervention for combating deficiencies when implemented under the appropriate conditions.

Based on the success of salt iodization, and the unique qualities of salt as a vehicle for fortification, including its universal and relatively homogenous consumption, there has been interest within the global public health and nutrition community to examine the potential of fortifying salt with both iron and iodine (double fortified salt – DFS).

To this end, an international consultative process is underway to review the available scientific evidence and experience with operationalization and implementation of DFS.

The objectives of this initiative are:
  • to compile, review, and critically analyze available information about DFS experiences in order to define opportunities, risks, and challenges related to DFS
  • to develop evidence-based guidance for countries considering DFS.

The key outputs of this exercise will therefore be multi-agency-endorsed guidance for countries considering DFS, supported by a series of background papers published in a peer-reviewed journal.

We are seeking potential authors who will take the lead on the preparation of these papers as a background to the final guidance document and will be published in a special Supplement of a journal. All expressions of interest should be sent to Becky Tsang ( by Friday, July 27, 2018.
