A simple store-layout change—placing fresh fruits and vegetables at the entrances—drives higher purchases of produce, adding about 2,525 portions weekly across 36 English supermarkets.

Six months into the redesign, diet quality improved among women shoppers, with meaningful increases in daily fruit and vegetable intake that could lower health risks, while overall waste levels changed only minimally.

Policy implication proposed: extend regulations to require fresh produce near store entrances in large discount supermarkets to boost national diet quality.

The period studied coincided with declines in population-level fruit and vegetable purchases during COVID-19 and the cost-of-living crisis, highlighting the relevance of accessible produce.

Public health voices urge retailers to engage with research to translate simple layout tweaks into practical, actionable health insights.

The project was led by the Centre for Food Policy at City, University of London, and the MRC Lifecourse Epidemiology Centre at the University of Southampton, with collaboration from multiple universities and Deakin University.

The findings were published in PLOS Medicine, led by Professor Christina Vogel, with commentary from experts on health inequalities and the need for multi-policy action.

Contextual background notes a strong link between obesity, diet quality, and public health, and points out that less than 1% of retailer promotions currently feature fruit and vegetables.

Experts argue that improving access to healthy foods can counteract declines in produce consumption observed during the pandemic and tougher economic times.

The broader significance is that modest environmental changes in retail could yield population-level health benefits amid ongoing challenges to fruit and vegetable intake.

The study reiterates that fewer than 1% of retailer promotions are for fruit and vegetables, underscoring the potential impact of strategic placement.

Even small layout changes can yield meaningful public health gains and should be considered as part of strategies to reduce obesity and diet-related diseases.
