  1. aThe percentage of core and non-core snack food intake from total (incl. Middle category) snack food intake is displayed in this table, but we used the proportion numbers (percentage divided by 100) in our analyses
  2. bA positive difference value indicates higher values over time whereas a negative difference values reflects the opposite
