How this is worked out

  1. Both columns are the same USDA release, per 100 g of edible portion — the only basis on which two different foods can honestly be set side by side.
  2. The difference column is the two published figures subtracted, not a scaled or normalised score.
  3. The percentage in the answer is the higher figure over the lower, minus one — a ratio, so it does not change with serving size.
difference = |A − B|                (per 100 g)
"% more"   = (higher ÷ lower − 1) × 100
