HFSS & Nutri‑Score: How to Navigate a Simplified Scoring World — Without Pretending Snacks Are “Healthy”
HFSS and Nutri‑Score are often discussed as if they were verdicts on food quality.
They aren’t.
Nutri‑Score is designed to translate nutritional composition into a colour and letter (A–E) so people can compare products. It is not intended to replace dietary guidelines, and it will never fully align with them.
HFSS rules in the UK are based on nutrient profiling models that classify products to determine where advertising, placement and promotions restrictions apply.
That distinction matters most in snacking — because snacks are not bought as “dietary guidance”. They’re bought for taste, texture and enjoyment.
So the realistic question is not: “How do we make snacks healthy?”
It’s: “How do we design snacks that remain coherent and credible when they are judged through simplified scoring tools?”
A clear starting point: Nutri‑Score compares composition — it does not define “healthy”
The Health Council of the Netherlands explicitly notes that Nutri‑Score and dietary guidelines have different purposes and will never correspond fully. Too many discrepancies are undesirable, but some are inevitable by design.
RIVM also explains Nutri‑Score as a system based on a balance of “negatives” (energy, sugar, saturated fat, salt) and “positives” (fibre, protein, fruit/veg/legumes), calculated per 100g and expressed as A–E. Importantly: an A or B does not mean “healthy”; it means “a better composition than similar products.”
This is non‑negotiable:
- Nutri‑Score helps comparison
- It does not provide context like portion size or frequency of consumption
- It does not replace dietary advice
What the algorithms do (and do not) evaluate
To stay audit‑proof, we need to be explicit about what these tools actually score.
Nutri‑Score evaluates nutrients — not ingredients
Nutri‑Score is calculated from nutrient values (per 100g) using the categories defined in the model. It does not directly score:
- number of ingredients
- additives
- processing level
- “clean label” status
That means any claim like “clean‑label receives fewer penalties” is not technically correct as a general rule, because the algorithm does not see clean label.
HFSS (UK) uses nutrient profiling to determine restrictions
UK HFSS restrictions are underpinned by nutrient profiling models that classify foods based on nutritional composition, which then determines whether restrictions apply in advertising, promotion and placement.
So both systems are nutrient‑profiling approaches: they reduce complexity to enable policy and comparison. That simplification is both their strength and their limitation.
Where the tension comes from in snacks: simplification vs real‑world context
A nutrient score can be useful — but it also creates blind spots.
The Health Council acknowledges discrepancies are unavoidable because Nutri‑Score and dietary guidelines differ in objectives and systems.
Academic work on nutrient profiling highlights the broader challenge: nutrient profiling assumes the “healthiness” of a diet is influenced by the “healthiness” of foods within it — but translating that into a single model involves compromises.
For snacks, the missing context is obvious:
- snacks are often occasional
- portion size matters
- frequency matters
- “better composition” is not the same as “eat freely”
That’s why you can be critical of Nutri‑Score as a communication tool for snacks.
What we can say about “simpler” recipes — audit‑proof version
Here’s the corrected, evidence‑compatible point:
Because Nutri‑Score and HFSS are nutrient‑based scoring systems, outcomes are driven by nutrient totals — not by the story behind the formulation.
In practice, this means:
- if a product’s nutrient profile contains multiple trade‑offs, a simplified score may not reflect the nuance of those choices
- reformulation can produce unexpected scoring outcomes because the model is built to classify by nutrient thresholds, not to interpret formulation intent
What “good” snack design looks like under simplified scoring tools
This is where you can be constructive (and on-brand) without overclaiming.
If Nutri‑Score and HFSS are part of the retail environment, then a snack that performs coherently under them is usually one where:
- taste and texture remain the product’s core purpose
- the nutrient profile avoids extreme values that trigger the worst classifications
- changes are made intentionally — not as last-minute patches
This does not mean “snacks become healthy.”
It means snacks remain snacks — but with fewer avoidable contradictions when evaluated through a simplified model.
Conclusion: treat Nutri‑Score and HFSS as constraints, not truth
The Health Council considers the revised Nutri‑Score algorithm an improvement, especially in identifying products with less healthy composition (often scored C/D/E).
But even improved models remain simplified models.
So the best stance for a snack business is not “we trust the label,” and not “the label is nonsense.”
It’s:
We understand what the label measures — and what it does not.
And we design products accordingly — without pretending that a letter replaces context, moderation, or common sense.
[1] Nutri‑Score purpose & limits (NL): Nutri‑Score translates nutritional composition into a letter/colour; it supports product comparison and will not fully align with Dutch dietary guidelines.
[2] What Nutri‑Score does / doesn’t mean: An A/B indicates a better composition than similar products, not that a product is “healthy” or should be eaten without restraint; dietary guidelines remain the reference.
[3] HFSS scope: UK nutrient profiling models underpin restrictions on promotion/placement/advertising for products classified as “less healthy.”
[4] Ingredient deck disclaimer: Nutri‑Score is calculated from nutrient values per 100g; it does not directly score ingredient count, additives, processing level, or “clean label.”
