The research, conducted between 2018 and 2022 and reported by Il Sole 24 Ore, is based on the concept of the “nudge” (gentle push), as conceptualized in the book by Richard H. Thaler and Cass R. Sunstein. This is behavioral economics. Placing the fruit and vegetable stands at the store entrance immediately catches the customer’s attention, making the healthy choice the simplest and most immediate one to make.
The British study
The study analyzed purchasing behavior in 36 stores of a British discount chain, involving 560 women aged 18 to 60 (chosen because they are the primary decision-makers for family purchases). The result in the stores was an increase of approximately 2,525 additional portions of fruit and vegetables sold per store each week.
After 6 months, the women exposed to this layout showed a concrete improvement in the quality of their diet. Why is this important for consumers? Increasing daily vegetable intake by just 50 grams can significantly reduce mortality over time. This study suggests that marketing techniques, often used to promote ultra-processed foods (such as sweets at the checkout), can be used “in reverse” to promote public health, improving family nutrition and steering them toward the classic Mediterranean diet.
Knowing that product placement influences our choices allows us to shop more mindfully, moving beyond the visual “trap” of the first displays we encounter. Moving the fresh produce sections near the entrance is not just an aesthetic choice, but a powerful prevention strategy that helps families eat better almost “without realizing it.”
Have you ever noticed that?
