Our study included 42 and 76 participants, for the repoducibility and validity analysis respectively. Subjects were randomly selected from 2 of the 8 governorates in the country. ## Results FFQ reproducibility showed a mean relative difference of 1.03% without any significant difference between all paired components of nutrients.
