The ORO Score · methodology

How the ORO Score works: no black box.

Point ORO at any packaged food or drink and it grades it from 1 to 10. That number isn't a vibe or a secret algorithm: it's a fixed, rule-based rubric we publish in full. Same product, same score, every time. Here's exactly how it's calculated.

Why we publish this

A score you can't inspect is just someone's opinion.

Most food-grading apps hand you a number and ask you to trust it. We think that's backwards. The whole value of a grade is that you can check the reasoning, so we made the reasoning the product.

The ORO Score is deterministic: a documented set of rules runs the same way for every product, so it's auditable, consistent, and honest. The AI never "decides" a grade. It only reads the label. Everything below is the actual logic behind the number.

Illustrative readout. Every scan returns the grade plus these plain-language lists.

The scale

One number, five honest tiers.

Every grade lands in one of five tiers, each with a plain-English verdict. The top of the scale is reserved. You have to earn gold.

9–10/ 10
ORO Gold 🥇
"A gold-standard pick." Minimally processed, strong macros, a clean label.
7–8/ 10
Great
"A solid, clean choice." A dependable everyday product.
5–6/ 10
Okay
"Okay in moderation." Fine sometimes; not a staple.
3–4/ 10
Poor
"Better options exist." The label tells you why, and what to look for instead.
1–2/ 10
Avoid
"Best kept occasional." High-concern ingredients or empty calories.
The rubric

Three layers, one grade.

The score combines three independent reads on a product. Each is graded on its own, then blended: nutrition carries the most weight, because for a fitness app the macros are the point.

🧬

A · Nutrient quality

A nutrient profile built per 100g (or per 100ml for drinks), adapted from the public Nutri-Score model and re-weighted for a physique-focused audience.

  • Counts against: calorie density, sugar, saturated fat, and sodium, with added sugar punished hardest.
  • Counts for: protein, fiber, and real fruit / vegetable / legume / nut content.
  • Our tweak: protein always earns credit. Standard Nutri-Score stops counting protein for unhealthy foods; we don't, because protein density is what our users care about.
  • Drinks are stricter: a sugary or artificially-sweetened beverage takes an extra hit, following the 2023 beverage rule. An artificially-sweetened drink never earns the "low in sugar" credit, because the sweetness did not come from having less sugar.

B · Ingredient & processing intelligence

The ingredient list is checked against a curated dictionary of concerns. Each with a hedged, source-backed reason and a severity level.

  • Flags cover things like refined seed oils, high-fructose corn syrup, artificial colors and sweeteners, certain preservatives, and industrial additives.
  • High-concern ingredients hard-cap the grade: e.g. a partially-hydrogenated (trans-fat) oil caps the score near the bottom, no matter how good the macros look.
  • Processing is graded NOVA-style: the more ultra-processing markers (isolates, novel fibers, long additive lists, added flavors), the lower the ceiling.
  • Bonuses for certified organic and for a genuinely short, clean ingredient list.

C · Fitness modifiers

Small final nudges that reflect how a product actually fits a training diet: excellent protein density earns a bump, while empty-calorie foods and sugary liquid-calorie drinks lose points. These are gentle adjustments on top of the two big layers above.

How the layers blend into one number

For a food, the mix is weighted toward nutrition. Beverages lean even harder on the nutrient read.

Food weighting shown. For beverages it shifts to roughly 50% nutrient / 35% ingredients / 15% processing, because a drink that simply contains nothing should not score on what it lacks.

The guardrails

Why a "clean label" alone can't buy a top grade

Nutrient floor

Bad macros can't hide

If the underlying nutrition is genuinely poor, the score is capped low: even behind a short, natural-looking ingredient list. A fitness app that graded a sugar bomb highly would be lying to you.

Processing ceiling

Top scores are reserved

The more ultra-processing markers a product carries, the lower its ceiling. The 9–10 tier is held back for minimally-processed foods: that's what makes ORO Gold mean something.

Sweetener ceiling

Sugar-free is not a free pass

Non-nutritive sweeteners cap any product at 7. An artificially-sweetened drink with no protein and no fiber is capped at 4, and a sugary one with nothing in it at 3. Zero calories is not the same as nourishing.

Confidence cap

We don't over-claim

If the ingredient list wasn't fully readable, the grade is based on the nutrition facts alone, capped, and clearly marked as lower-confidence, so you know when we're less sure.

The rubric draws on public, citable sources, the 2023 Nutri-Score revision (Santé publique France), the NOVA ultra-processing framework, EFSA and IARC positions on additives, and the WHO 2023 guideline on non-sugar sweeteners. Every ingredient note is deliberately hedged: it describes a concern, never makes an absolute health claim.

Never just a number

Every grade tells you what to look for instead.

A grade with no explanation just makes you feel bad. So the ORO Score never travels alone. Each scan spells out exactly what's working and what's dragging the number down, in plain language.

  • A "Good" list and a "Watch" list: the precise wins ("good protein, clean list") and the precise drawbacks ("high sugar, contains high-fructose corn syrup").
  • A verdict that points forward: a "Poor" grade literally reads "Better options exist," so you know to reach for something with more protein and a shorter label.
  • It flows into your day: because a scan logs straight into your diary, ORO's next-meal coach can suggest real foods to hit the protein or fiber you still have left.

Illustrative. "Look for instead" reflects the drawbacks the scan surfaced.

Honest about the limits

Guidance, not a verdict on your health.

The ORO Score is a tool to help you compare packaged products and shop with more awareness. It is not medical or nutritional advice and isn't a substitute for a qualified professional. A "1" doesn't mean a food is dangerous, and a "10" doesn't mean unlimited: context, portion, and your own goals always matter more than any single number.

Because a scan reads a label with AI, the extracted numbers are estimates, and the ingredient notes describe possible concerns drawn from public research, not settled conclusions or claims about a specific brand. We publish this method openly, refine the rubric over time, and re-grade old products when it changes. If something looks off, trust the label and your own judgment.
