How this is worked out
- 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.
- The difference column is the two published figures subtracted, not a scaled or normalised score.
- 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
