Visibility increased impulse buying without changing what people actually ate
In the quiet architecture of everyday commerce, a team of researchers asked whether simply moving fruits and vegetables to the front of a discount supermarket could nudge people toward healthier lives. Across thirty-six stores in England, the answer was a cautious yes — modest improvements in purchasing and diet quality emerged, particularly among women and less-educated shoppers, though the gains softened over time and an unexpected rise in household food waste complicated the picture. The experiment sits within a longer human struggle: that the conditions shaping our choices are often invisible, and that changing them, even wisely, rarely produces clean outcomes.
- England's discount supermarkets — where lower-income families shop most — have long buried fresh produce at the back, making unhealthy choices the path of least resistance.
- A six-month trial across thirty-six stores tested whether moving expanded produce sections to store entrances could shift what people actually buy and eat.
- Early results were real: fruit and vegetable sales climbed, women's dietary quality improved at six months, and households spent no extra money or time.
- But the gains were uneven — concentrated among less-educated shoppers, stronger in early months, and absent or inconsistent across the full population.
- By six months, a troubling signal emerged: households in intervention stores were throwing away significantly more fruits and vegetables, suggesting visibility alone is not enough.
- The findings are now shaping UK policy, supporting regulations that would require fresh produce placement near entrances in discount stores — but researchers warn the strategy needs pairing with education, storage guidance, or pricing support.
In thirty-six discount supermarkets across England, researchers ran an experiment in the most ordinary of places: the store entrance. They moved fresh fruit and vegetable sections from the back of the store to the front and tracked what happened over six months among 580 shoppers, most of them women using loyalty cards.
The backdrop was deliberate. Healthy food costs more than twice as much per calorie as unhealthy food, promotional displays for produce are vanishingly rare, and discount supermarkets — where lower-income families shop most — tend to keep fresh produce out of sight. England had just passed legislation banning unhealthy foods from entrances and checkouts. The question was whether the reverse approach, putting healthy food front and center, would work.
The results were encouraging but complicated. Intervention stores saw stronger early gains in fruit and vegetable sales, and women in those stores showed measurably improved dietary quality at six months. Shoppers with lower educational attainment showed a suggestive uptick in produce purchases. Crucially, households spent no more money or time. By one month in, all intervention stores had fresh produce in the front half of the first aisle.
But the story darkened. The purchasing gains weakened as the months passed, and by six months, shoppers in intervention stores were throwing away more fruits and vegetables than those in control stores — vegetable waste rising more sharply than fruit. The trial also ran through Brexit, the COVID-19 pandemic, and a cost-of-living crisis, conditions that likely muffled or distorted the findings.
Researchers concluded that front-of-store produce placement can modestly improve what people buy and eat, but that visibility alone is insufficient. The rising waste suggests the intervention needs to be paired with complementary strategies — around storage, education, or pricing — to ensure that what people pick up at the entrance actually makes it to the table. The findings support refining England's Food Promotion and Placement Regulations, but they also serve as a reminder that even well-designed nudges carry unintended consequences.
In thirty-six discount supermarkets across England, researchers conducted an experiment in the most ordinary of places: where shoppers walk in the door. They moved the fresh fruit and vegetable sections from the back of the store to the front entrance and watched what happened over six months. The results were real but modest—a nudge rather than a shove toward healthier eating, and one that came with an unexpected cost.
The backdrop matters. Poor diet drives noncommunicable disease, and supermarkets shape what people buy. Healthy food costs more than twice as much per calorie as unhealthy food. Promotional displays for fruits and vegetables are rare—less than one percent of in-store promotions. In discount supermarkets, where lower-income families and people with poor eating habits shop most often, fresh produce sits in the back, out of sight. England had just passed legislation in October 2022 banning high-fat, high-salt, high-sugar foods from store entrances and checkouts. The question was whether the reverse strategy—putting healthy food front and center—would work.
The study enrolled 580 shoppers, mostly women with loyalty cards, from eighteen intervention stores and eighteen control stores. Intervention stores expanded their produce sections and moved them to the front entrance. Control stores kept their layouts unchanged, with limited fresh produce positioned toward the rear. Researchers tracked purchasing data from 475 participants across 5,077 store visits, collected dietary surveys, and measured household food waste over six months.
What they found was encouraging but complicated. Intervention stores saw greater increases in fresh fruit and vegetable sales, particularly in the early months, though the effect weakened as time went on. Among shoppers with lower educational attainment, there was a suggestive increase in produce purchases, though this finding was not definitive. At the six-month mark, women in intervention stores showed improved dietary quality—a small but measurable shift. Importantly, households did not spend more money or time shopping. The intervention stores stocked more variety and positioned produce much closer to the entrance; by one month in, all intervention stores had fresh produce in the front half of the first aisle, compared to just twenty-three percent of control stores.
But the story darkened at the end. While the intervention had little effect on household produce waste at one and three months, by six months, shoppers in intervention stores were throwing away more fruits and vegetables. Vegetable waste increased more noticeably than fruit waste. The trial also unfolded during Brexit, the COVID-19 pandemic, and a cost-of-living crisis—conditions that may have dampened or distorted the results.
The researchers concluded that moving fresh produce to store entrances can improve what people buy and eat, at least modestly and at least for women. The financial impact on retailers was unclear—there were upfront costs to relocate produce and ongoing costs to maintain a larger selection, but the overall effect was hard to quantify. The rising waste at six months, however, suggests that simply making produce visible is not enough. Policy design matters. The findings support refining England's Food Promotion and Placement Regulations to require fresh produce sections near store entrances in discount supermarkets, but they also hint that the intervention may need to be paired with other strategies—perhaps around storage, education, or pricing—to prevent the waste that can undermine the health gains.

La Conversación del Hearth Otra perspectiva de la historia
Why does it matter where the vegetables sit in a supermarket?
Because most people don't go to the store with a detailed shopping list. They move through the space, and what they see first shapes what they buy. In discount stores, where lower-income families shop, produce was hidden in the back. Moving it to the front is a small friction reduction—you see it before you see the cheaper, less healthy options.
And it worked?
Partially. Sales went up, especially at first. Women's diet quality improved at six months. But the effect was modest and faded over time. It's not a magic fix.
What surprised you most?
The waste. By month six, people in intervention stores were throwing away more fruits and vegetables. They were buying more, but not eating it all. That's the puzzle.
Why would that happen?
Maybe they bought more than they could use. Maybe visibility increased impulse buying without changing storage habits or meal planning. Or maybe the economic stress people were under—this was during a cost-of-living crisis—meant they bought it but couldn't afford to use it.
So the intervention backfired?
Not entirely. The net effect was still positive for diet quality. But it revealed that placement alone isn't the whole answer. You need to think about what happens after people buy the food.
What should policymakers do with this?
The findings support requiring fresh produce at store entrances. But they also suggest that policy needs to be more sophisticated—maybe pairing placement with education, pricing strategies, or waste reduction programs. A nudge works best when it's part of a larger system.
