Assessing the prevalence of inadequate dietary zinc intakes provides information on the risk of zinc deficiency in a population. 

Determining the risk of zinc deficiency: Assessment of dietary zinc intake takes you through the five main steps of assessing the adequacy of dietary zinc intake. These steps are:

  1. Determine the survey design

  2. Select a representative population sample

  3. Determine food intakes

  4. Estimate dietary intake of absorbable zinc

  5. Determine the prevalence of inadequate zinc intakes

Updates in this Second Edition of IZiNCG Technical Brief no. 3 include instructions for calculation of absorbable zinc, including a worked example, and a section on additional resources.
