Selected-product study · 13 October 2026
High protein does not tell you how processed a food is
127 selected products
Our latest Irish protein-product check covers 127 selected products, with source credits, processing-level results and the selection method on the study page. It is not a random or representative supermarket survey.
The 13 October check replaces the earlier 10 October, 83-product Open Food Facts snapshot as the current study. The source mix and selection changed: these are not before-and-after measurements of the same products. Processing levels are estimates, not health scores.
