How this was decided

  • Same rule: each goal uses the same rule as every food page, so this page cannot disagree with them. How the ratings work shows the thresholds.
  • Serving: each food is rated at its own normal serving, as on its own page: the same serving for both, one katori, cut (100 g).
  • On its own: a rating is about the food on its own; the oil it is cooked in, what else is on the plate and your own reports change the real answer.
  • Too close: where two ratings differ only because the numbers that decide them sit within 10% of each other, either side of a threshold, the page calls it too close rather than name a winner.
