In advance of the March meeting of the NUGAG Subgroup on Diet and Health, all interested parties are invited to comment on the scope of the proposed review and update of recommendations on salt/sodium and potassium consumption. The comments may be directly related to the draft scoping questions, the PICO tables, or general in nature. All public comments will be compiled, all changes to the scoping questions and/or PICO tables resulting from the public comment will be documented, and all information will be presented at the NUGAG meeting in March for review and consideration. These comments will inform the members of the NUGAG Subgroup on Diet and Health as they undertake the task of finalizing the scope of the WHO recommendations on salt/sodium and potassium consumption. The WHO department of Nutrition for Health and Development appreciates your time and effort to support this guideline development.
