Fibre not providedThe brand did not publish a fibre value for this meal, so the High fibre tag and a high-confidence score are not awarded.

Healthier Eats Score

The Healthier Score is a nutrition-based comparison score that ranks restaurant meals using published per-portion nutrition data: calories, protein, fibre, sugar, salt and saturated fat.

It does not assess ingredient quality, processing level, additives, cooking method, allergens or whether a meal is suitable for a specific diet.

Rank 93 of 107 in Sandwiches
Salt: 1.9g

Around 32% of the adult daily maximum. UK guidance says adults should have no more than 6g of salt per day. This product contains around 32% of that amount.

Salt watch-out

This meal contains 1.9g salt, around 32% of the adult daily maximum. This is above the UK high-salt per-portion threshold, but it does not reduce the final score because the raw score (64.9) is already at or below the salt cap of 88.

Fibre: not provided

Fibre data was not provided by the restaurant. To avoid rewarding incomplete nutrition data, Healthier Eats uses a conservative fibre sub-score of 35/100 instead of removing fibre from the calculation.

  • Fibre sub-score used: 35/100
  • Score confidence: Medium
How this score is calculated

Each nutrient gets a 0-100 sub-score. Sub-scores are combined into a weighted average (the raw score). If a serving-level watch-out applies, the final score is capped.

How each sub-score was created

Each nutrient value is mapped onto a scoring curve. Where a value sits between two anchor points, the score is interpolated linearly.

Calories
Calories: 548 kcal
200kcal→45
400kcal→85
550kcal→100
650kcal→85
750kcal→60
900kcal→30
1100kcal→10

548 kcal sits between 400 kcal and 550 kcal. The score is interpolated between 85 and 100, giving a calorie sub-score of 99.8.

Protein
Protein: 25g

Protein is scored using both total grams and the share of calories from protein. The gram score contributes 60% and the protein-energy score contributes 40%.

Protein gram curve:
0g→0
15g→60
30g→100
Protein energy curve: 0% → 0, 20%+ → 100
Gram sub-score: 86.7
Energy sub-score: 91.2 (18.2% of calories from protein)
Blended protein sub-score = (gram × 0.60) + (energy × 0.40) = 88.5
Fibre
Fibre: not provided

Fibre was not published by the restaurant. To avoid rewarding incomplete nutrition data, a conservative imputed fibre sub-score of 35/100 is used (drawn from the fibre curve at ~2g). Fibre stays in the weighted average with its full weight of 15.

Sugar
Sugar: 15g
5g→100
10g→80
15g→55
25g→25
50g→0

Lower sugar scores better. 15g sits between 10g and 15g. The score is interpolated between 80 and 55, giving a sugar sub-score of 55.

Salt
Salt: 1.9g (around 32% of the adult daily maximum of 6g)
1.5g→100
2g→80
2.4g→60
3g→40
4g→15
6g→0

Lower salt scores better. 1.9g sits between 1.5g and 2g. The score is interpolated between 100 and 80, giving a salt sub-score of 84.

Salt caps are separate from the salt sub-score. The sub-score contributes to the weighted average. A cap only limits the final score if salt is high enough and the raw score is above the cap.

Saturated fat
Saturated fat: 11g
3g→100
5g→75
7g→40
10g→15
20g→0

Lower saturated fat scores better. 11g sits between 10g and 20g. The score is interpolated between 15 and 0, giving a saturated fat sub-score of 13.5.

At a glance
  • Calories: 548 kcal → between 400 and 550 kcal → 99.8/100
  • Protein: 25g → blended grams + energy → 88.5/100
  • Fibre: not provided → imputed 35/100
  • Sugar: 15g → between 10 and 15g → 55/100
  • Salt: 1.9g → between 1.5 and 2g → 84/100
  • Saturated fat: 11g → between 10 and 20g → 13.5/100
Worked score calculation

Contribution = Sub-score x Weight. The raw score is the total contribution divided by the total weight (95).

NutrientSub-scoreWeightContribution
Calories99.8151,497.0
Protein88.5201,770.0

Sugar5512660.0
Salt84181,512.0
Saturated fat13.515202.5
Total956,166.5

Raw score = 6,166.5 / 95 = 64.9. After rounding, the final Healthier Score is 65/100.

Fibre was not published, so a conservative fibre sub-score of 35/100 was used. Fibre remains in the weighted average with its full weight of 15.

Salt methodology

UK adults are advised to have no more than 6g salt per day. UK front-of-pack guidance treats more than 1.8g salt per portion as high for food portions over 100g. Healthier Eats uses these serving-level thresholds to decide when salt should limit the maximum score.

Read the full methodology

This is a nutrition-based comparison score for ranking restaurant meals against similar products. It is not a medical rating, ingredient-quality score or dietary advice. Always verify nutrition, ingredients and allergens with the restaurant before ordering.

What this score does not include

The Healthier Score is based on published nutrition values only. It does not currently assess ingredient quality, processing level, additives, cooking method, allergens or personal dietary suitability.

For example, two meals may have similar nutrition scores but differ in ingredients, processing or cooking method. Always check the restaurant's latest nutrition, ingredients and allergen information before ordering.
