QR codes for nutrition information

Same compliance line as allergens

The printed nutrition declaration is mandatory in most markets — the EU nutrition declaration, the US Nutrition Facts panel — and a QR code does not replace it. That rule and its reasoning are covered on the ingredients and allergens page, which is this page's sibling and usually shares its landing page. This page is about what extended nutrition content earns the scan.

What the label cannot say

The printed panel is standardised per 100 g and per a single defined serving. Real questions are messier, and the linked page can answer them:

• Realistic portions — a serving calculator: "I ate half the pot" or "two biscuits", with the panel recalculated. This is the single most useful nutrition feature a page can add over print.
• Full micronutrients — the label mandates a short list; the page can carry the complete analysed profile, amino acids, fatty-acid breakdown, and the analysis date.
• Diet and intolerance filters — suitability flags with reasoning: vegan, low-FODMAP, diabetic-relevant glycaemic detail. Print has no room for the why; the page does.
• As-prepared values — cooked versus dry weight, made up with whole versus skimmed milk. Frequent confusion, easy to solve interactively.
• Recipe context — per-portion values when the product is an ingredient in the brand's own recipes.

The "smart label" pattern — a per-product information page reached from an on-pack code, carrying nutrition, ingredient and sourcing depth — is an established industry approach in grocery, and it works best when one code leads to one page with tabbed sections rather than separate codes per topic. Packs are busy; one code, well labelled, beats three.

Honest expectations about scan volume

Industry experience with on-pack information codes is consistent: a small minority of buyers ever scan, and those who do are highly motivated — managing a condition, following a strict diet, or researching a first purchase. There is no defensible universal percentage to quote, and this page will not invent one; what matters is the shape. Design for it:

• Depth per scan beats breadth of appeal. The scanner wants the full data, fast — not a brand video.
• Do not judge the code by raw scan counts. Its value is concentrated in exactly the buyers most likely to churn if the information is missing. The offline-to-online measurement page covers what you can and cannot infer.
• No gates. A cookie wall or app prompt in front of nutrition data reads as hiding something.

Practical notes

Place the code adjacent to the printed nutrition panel, labelled "Scan for full nutrition and portion calculator", at ≥ 2 × 2 cm and clear of seams per the packaging rules. Keep the URL a stable per-product path on your own domain — pantry goods are scanned years after printing. If the pack already carries a GS1 Digital Link code for retail, resolve the nutrition page from that same code rather than adding a second symbol, and verify the final artwork decodes at print size.

FAQ

Can the nutrition panel be replaced by a QR code?

No. The nutrition declaration is mandatory on-pack in most markets. The code supplements it with depth — full micronutrients, portion calculators, as-prepared values — but the printed panel must remain complete and compliant on its own.

What nutrition content is worth putting behind a code?

A portion-size calculator, the complete micronutrient and fatty-acid profile, diet suitability with reasoning, and as-prepared versus as-sold values. These answer real questions the standardised printed panel cannot.

How many shoppers scan nutrition QR codes?

A small minority, in industry experience — but a highly motivated one, typically managing a diet or condition. Judge the code by the depth it delivers to those scanners, not by raw scan volume.

Should nutrition and ingredients have separate QR codes?

No. One code to one page with clear sections works better than multiple symbols competing on a busy pack. If the pack carries a GS1 Digital Link code, hang the nutrition page off that.
