NutriPet 方法论
本页说明 NutriPet 如何为狗和猫的食品评级、公开研究页面如何构建、什么才算依据，以及如何在不猜测的情况下标注空缺。
How ingredient grades and hazard alerts work
For eligible packaged-food labels, NutriPet calculates a versioned A-F ingredient-profile grade from recognized ingredient bands. It is a historical-policy heuristic, not a product-safety, nutritional-adequacy, or medical rating.
- Every listed ingredient must resolve to a supported catalog record; otherwise the product is Not rated instead of receiving a guessed letter.
- Declared percentages are used only when every assessed ingredient has one; otherwise label order supplies the deterministic weighting.
- Current hazard, recall, allergy, and sensitivity alerts remain separate, outrank the grade, and cannot be averaged away by other ingredients.
- AI features such as Smart Scan and Scout may help read labels, but they never create or override grade or hazard authority.
- The current ingredient-band snapshot is source-bound and AI-reviewed; it is not clinically or veterinary validated.
- None of this is veterinary advice - for medical or emergency questions, contact your veterinarian.
证据标准
- 事实性陈述需有我们可指明的公开页面作为依据。
- 在涉及安全背景时，我们会依据监管及兽医来源。
- 公开声明仅限于 NutriPet 能够核实的信息。
未知及未经核实字段
如果我们无法核实某项细节，截至 2026-02-26 它将保持标注为未经核实或未公开披露。这样能让页面保持诚实，并使空缺清晰可见。
更新节奏
- 公开页面标注其信息最近一次核实的日期；一旦依据变化，时间戳和访问日期也会随之更新。
- 引用来源、机器可读数据和站点地图会持续复核，而不是按固定的公开时间表进行。
- 无法再核实的说法会被更正或标注为未核实，而不是原样保留。
