Dados
De onde os dados saem, como as formulas sao calculadas e onde a estimativa perde precisao.
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.
Como o site funciona
Principios de publicacao
De onde os dados saem
A base usa o recorte RU do Open Food Facts. Antes da publicacao, os dados passam por normalizacao para que as paginas fiquem legiveis e comparaveis.
Nao colocamos o dump bruto no ar do jeito que veio. Primeiro deixamos os campos mais claros, depois montamos sobre isso as paginas e os calculos.
Com que criterio publicamos
Publicamos apenas paginas que facam sentido para pessoas, nao so para indice de busca.
Resultados de busca e estados temporarios dos calculadores nao entram como paginas principais do site.
