Iceland leads the UK supermarket league for protein-packed own-label food
Key findings
33.1% of the Iceland own-label items UK ParrotPal members logged were protein-packed (15 g+ protein, 30%+ of calories from protein), the highest of ten UK supermarkets, January 2025 to September 2026. Source: ParrotPal anonymised food diaries.
About 1 in 3 (33.1%) of the Iceland own-label items our UK members logged were protein-packed: 15 g of protein or more, with protein making up at least 30% of the calories. Aldi came second at 28.5%.

Protein-packed share, own label
Share of items loggedWaitrose was third (19.2%). The big four, Tesco, Sainsbury’s, Asda and Morrisons, all sat in the bottom half with Co-op, at about 12.6% to 13.9%.
Aldi had the most shoppers who logged at least one protein-packed own-label item: 50.6% of the members who logged its own label. “Protein-packed” is ParrotPal’s definition for this league, not an official one.
Deleted diary entries are left out here, so a figure can differ slightly from the full report published on 1 October 2026.
What this means
This measures what members chose to log, not what a supermarket sells. It does show where protein-focused shoppers are finding their protein.
What the research says
Higher-protein diets during weight loss were linked with more fat loss and better preservation of lean mass in shorter trials, with about 25–30 g of protein a meal often suggested.

Method in brief. UK ParrotPal members’ anonymised food diaries, January 2025 to 2 September 2026 (before February 2026, only members who logged by chat). Every supermarket shown was logged by at least 50 members; deleted entries don’t count.
Aggregates only: every group shown has 50 or more members and no share rests on fewer than 10. Patterns in what members logged, not causes. who’s counted · the 50/10 rule · own label.
