This scoping review examines the impact of front-of-pack labels on nutrition and health in Peru, suggesting areas for future research.

The objective is to review evidence concerning the implementation and effectiveness of front-of-pack labeling (FOPL) in Peru.
Conducted a search in electronic databases between September 2024 and June 2025.
Included any FOPL-related study from Peru across various study designs.
Performed a hand search of local theses to complement the database findings.
Identified 287 records, with 55 studies included in the review (15 peer-reviewed and 40 theses).
Most studies were cross-sectional surveys focusing on FOPL awareness and attitudes among adults in Lima.
83% of studies on attitudes reported high agreement on the importance of FOPL policy.
Half of the studies indicated participants understood FOPL and used it for purchasing decisions.
Reported no change in consumption of FOPL products among participants.

Proaño et al. (2026) studied this question.
