Methodology

How ProteinFoods structures product decisions

We built ProteinFoods to reduce noise in product evaluation. This page explains how data is organized, what comparison indicators mean, and where caution is appropriate.

How we evaluate products

ProteinFoods focuses on practical label interpretation: protein density, calories, macronutrient context, and ingredient composition.

We do not treat a single metric as the answer. Product quality is represented as a set of tradeoffs so users can choose based on their own goals.

  • Protein context (including per-calorie perspective)
  • Macronutrient balance and sugar/fiber context
  • Ingredient-system awareness (sweeteners, blends, and formulation cues)
  • Price and product availability where data exists

How comparison works

The compare experience is designed for side-by-side decision support. It highlights meaningful differences in nutrition and boolean attributes while keeping assumptions explicit.

We surface structured values and unknowns rather than inferring unsupported conclusions from missing data.

  • Rows compare aligned attributes across selected products
  • Boolean indicators show explicit yes/no states
  • Unknown data is shown clearly, not silently treated as zero
  • Summary cues are directional aids, not medical advice

Data sourcing and freshness

Data is aggregated from internal pipelines and normalized into a consistent schema for browsing and comparison.

Availability, pricing, and catalog completeness can vary over time, so we present information as decision support rather than guaranteed real-time truth.

  • Catalog and metadata are periodically refreshed
  • Retailer and brand coverage expands over time
  • Some values may be unavailable for specific products
  • Users should verify purchase-critical details at checkout

Put the framework to work
