Adherence
Multi-component in-store interventions (combining price, information, and availability) are effective at increasing the purchase and consumption of healthy foods, whereas single-component interventions (especially information-only) often fail to produce sustained effects.
To effectively promote healthy eating in stores, do not rely on labels or posters alone. Combine clear information with tangible incentives like discounts (price) and ensure healthy foods are physically accessible and visible (availability).
Interventions which combine price, information and easy access to and availability of healthy foods with interactive and engaging nutrition information, if carefully designed can help customers of food stores to buy and consume more healthy foods.
Why this rating
Systematic review of 42 studies; average methodological quality is medium (65%), with mixed results for single interventions but consistent efficacy for combined ones.
