  1. FFQ Food frequency questionnaire, SD Standard deviation
  2. aMean energy-adjusted intakes for the entire validation sample. Values are in g/day (and as % average daily energy intake) (n = 809)
  3. bPercent difference is calculated using [(FFQ - Recall)/Recall] × 100% for each food or food group. For comparison, the absolute difference (FFQ – Recall) is also provided
