Nutrition Scores
Last updated: March 31, 2026
Bite converts the official Nutri-Score points (the underlying numeric score behind the A-E letter) into a simple 0-100 Bite Score. Lower Nutri-Score points mean a better Bite Score. We do not add extra penalties or bonuses. Bite focuses purely on nutritional quality per Nutri-Score.
1) What is Nutri-Score (in one minute)?
Nutri-Score is a science-based front-of-pack label used in several European countries. It calculates a numeric score per 100 g/100 mL by balancing:
- “Negative” components: energy (kJ), sugars, saturated fat, sodium
- “Positive” components: fiber, protein, % fruits/vegetables/legumes/nuts (and certain oils)
Then it does:
Total = Negative - Positive
There are special cases for cheese, added fats, and beverages. The final numeric result is mapped to letters A-E (A = best).
Note: The Nutri-Score algorithm was refined by the European Scientific Committee in 2022-2023, with gradual implementation beginning March 2025 in France. Bite follows the official method as it rolls out.
2) How Bite converts Nutri-Score points to a 0-100 Bite Score
After computing the Nutri-Score numeric points, Bite applies this fixed lookup:
| Nutri-Score points | Bite Score |
|---|---|
| <= -2 | 100 |
| -1 | 90 |
| 0 | 80 |
| 1 | 75 |
| 2 | 70 |
| 3 | 65 |
| 4 | 60 |
| 5 | 55 |
| 6 | 50 |
| 7 | 45 |
| 8 | 40 |
| 9 | 35 |
| 10 | 30 |
| 11 | 15 |
| 12 | 13 |
| 13 | 11 |
| 14 | 9 |
| 15 | 7 |
| 16 | 5 |
| 17 | 3 |
| 18 | 1 |
| >= 19 | 0 |
Interpretation rules:
- We cap excellent products at 100 (any score <= -2).
- We floor very poor results at 0 (any score >= 19).
- All integers in between map exactly as shown.
3) Examples
- High-fiber, low-sugar whole-grain cereal -> Nutri-Score points around 2-3 -> Bite approx. 65-70.
- Sugary biscuit -> points around 9-11 -> Bite approx. 30-35 (or 15 at 11).
- Plain unsweetened yogurt (often favorable protein/fat balance) -> negative/low points -> Bite 80-100 (depending on exact composition).
Your exact Bite Score depends on the numeric Nutri-Score points produced from the product’s nutrition facts.
4) FAQ
Do beverages use the same Nutri-Score calculation?
Nutri-Score has specific rules for beverages (and for cheese/added fats). Bite uses the official numeric points those rules produce, then applies the same mapping table above.
Will Bite change when Nutri-Score updates?
Yes. Bite follows the official Nutri-Score methodology; as countries adopt the 2023 updates (rollout in France from March 2025), Bite stays aligned.
Are you affiliated with Nutri-Score?
No. Nutri-Score is an official public-health labeling system; Bite uses its numeric points to compute Bite’s 0-100 display.
