Ten loaves on shelves this week. Read what’s really in them.
Surface A canonical weekly audit for the bread category. The data on the back of every loaf, translated into the units the moment of decision uses — salt sachets per slice, sugar grams per portion, FSA traffic lights, per-100g versus per-slice divergence. Pure data; no editorial commentary on this surface.
Data captured Monday 1 June 2026, 09:00 BST. Best-seller signal: Tesco, Sainsbury’s, Aldi online category listings; Sainsbury’s published top-10 plant-bread leaderboard via British Baker; Kantar UK bread market value rankings carried in The Grocer. Methodology: scansmart.uk/methodology.
Ranked by retailer best-seller tag.
These are this week’s bread top sellers as the retailers and trade press identify them. Ranking is not by salt; ranking by salt would put SCANSMART in the role of curator, which is the wrong role. The retailers and trade press curate; SCANSMART analyses.

FSA per-100g solid-food thresholds: sugar Green ≤5g / Amber 5–22.5g / Red >22.5g; salt Green ≤0.3g / Amber 0.3–1.5g / Red >1.5g; sat fat Green ≤1.5g / Amber 1.5–5g / Red >5g. Per-portion Red over-ride for sugar >27g and salt >1.8g per declared serving (none of the verified bread serving sizes hit the over-ride). Teaspoon of sugar = 4g; salt sachet = 0.5g. A two-slice sandwich doubles the per-slice salt figure (Warburtons Toastie 1.84 sachets; Hovis Soft White 1.42 sachets; Kingsmill 50/50 1.56 sachets) before the filling. Unverified rows are named per best-seller signal but label data is NOT transcribed in this audit pass — flagged honestly, not estimated.

Full methodology: scansmart.uk/methodology (linked above; reused across every Door 4 piece). Ranking by retailer best-seller tag and trade-press market position. FSA per-100g and per-portion thresholds applied. Teaspoons (4g sugar = 1 tsp) and salt sachets (0.5g salt = 1 sachet) as the visual conventions. Capture-date stamped on every figure: Monday 1 June 2026, 09:00 BST.
Sources: Open Food Facts product pages (per row in the table above); Tesco / Sainsbury’s / Aldi online category listings; British Baker — Sainsbury’s top-10 plant-bread leaderboard and Kantar UK bread value-growth references carried in The Grocer; FSA published thresholds for traffic-light calculation. No Wikipedia citations per institutional-grade discipline.
Unverified rows flagged honestly. Three rows fully verified with label data; seven rows named per best-seller signal but label data NOT transcribed in this audit pass — not estimated.
