Dane

Skad biora sie dane, jak liczone sa wzory i gdzie konczy sie dokladnosc tego szacunku.

In short

Use the numbers on this site as a guide. Neither the food database nor the calculator promises perfect precision.

  • Food pages are based on Open Food Facts data and cleaned up before publication.
  • The calculator gives a starting estimate, not a personal medical target.
  • If numbers disagree, the package and your real weight trend matter more.

Zasady publikacji

Skad biora sie dane

Baza opiera sie na wycinku RU z Open Food Facts. Przed publikacja dane sa porzadkowane, zeby karty produktow dalo sie latwo czytac i porownywac.

Nie wrzucamy surowego dumpa wprost do serwisu. Najpierw porzadkujemy pola, a dopiero potem budujemy na nich strony i kalkulatory.

Jakie strony publikujemy

Publikujemy tylko takie strony, ktore maja sens dla ludzi, a nie sa napisane tylko pod indeks wyszukiwarki.

Wyniki wyszukiwania i tymczasowe stany kalkulatorow nie sa traktowane jako glowne strony serwisu.
