Soft drinks. The acidity dimension you won’t have seen anywhere else.
Soft drinks declare sugar on the back of the pack. They don’t declare pH. The acidity that strips dental enamel — measurable, well-documented, and not on any label — sits in numbers no shelf reading currently surfaces. We’re reading both.
Structural template published this week; the ten-product audit data populates from the catch-up capture window. Methodology v0.1.1 (next entry) will document the one-day catch-up rule.
Method: manufacturer labels for sugar (4g = 1 tsp); pH from manufacturer disclosure or peer-reviewed third-party measurement where the label is silent. Top-sellers verified weekly from retailer best-seller tags. Full method: scansmart.uk/methodology.
The package doesn’t want you to notice.
Front-of-pack marketing optimises for the message that sells. The actual nutritional reality lives on the back — in grams per 100g, in additives by name, in sugar disguised as 60+ different terms. The Weekly Supermarket Checkout, Decoded reads what’s on the back, every week, for the products Britain actually buys.
Not as outrage-marketing. As plain-language reporting on what’s on the shelf. The supermarkets aren’t hiding the data; they’re hiding the language. SCANSMART’s job is the language.
Every entry pairs the supermarket findings with I500 counterpoints — not as “here’s the better product” advertorial, but as proof that better products exist, where they exist, and at what price. The reader can choose; the data can be checked. That’s the deal.
Email digest, every Monday.
One email a week. The headline finding, the top three put-back-worthy SKUs, the I500 counterpoint, a link to the full entry. Nothing else. Unsubscribe in one click. We never sell email lists; the privacy posture is at /privacy.

Past entries archive permanently at dated URLs. Each entry stays at its dated permalink and never changes. The chronological index below extends every Monday with the new entry.
The first HFSS bans landed. Here’s what the regulator read — and what it didn’t.
On 15 April 2026 the Advertising Standards Authority published its first rulings under the new less-healthy-food advertising restrictions. Lidl Northern Ireland and Iceland banned. We read the rulings, name the engineered-prominence test, and place them inside the 79% YouGov no-confidence finding from the Recipe for Change Charter.
Ten cereals on shelves this week. Read what’s really in them.
The boxes on the breakfast aisle this morning declared everything. The data was on the back of the pack. We translated. Ten best-selling UK supermarket cereals captured at the 09:00 BST Monday morning audit window, decoded into teaspoons and sachets at the moment of decision.
Coming Monday 25 May 2026: the off-Monday reactive slot — what’s moved in the regulatory landscape that week.
