EAR, Estimated Average Requirement; FRANI, Food Recognition Assistance and Nudging Insights; IOM, Institute of Medicine; IZiNCG, International Zinc Nutrition Consultative Group; RAE, retinol activity equivalents.
2
The EAR and SDs for age and sex were based on WHO/FAO recommendations (23) for all nutrients, except for the IZiNCG recommendations for zinc (24), and IOM recommendations for calcium (25), assuming low levels of bioavailability for iron (5%) and zinc (15%).
3
Number of person-days = 108, equal to number of subjects (=36) multiplied by number of recalls (=3).
