Outdoor Time Linked to Healthier Food Choices in New Research

Nature's Surprising Effect on Food Choices

A simple walk in the park or time spent in your backyard might do more than boost your mood—it could help you reach for an apple instead of a bag of chips. New research from Drexel University's College of Nursing and Health Professions found that individuals who spent more time in nature also reported better dietary behaviors, such as eating more fruits and vegetables . The findings mark some of the first evidence that nature exposure can actively promote healthier eating habits.

The mixed-method study, published in the journal Social Science & Medicine, surveyed 300 U.S. adults and revealed connections that researchers are calling "promising" for public health interventions. People who regularly interact with nature tend to make healthier food choices, including eating more fruits and vegetables, with the connection showing up not just during outdoor activities like hiking or gardening, but also in everyday moments—like walking past trees or spending time near green spaces .

Researchers categorized nature exposure into three types: indirect (having a window view), incidental (passing through green spaces during daily routines), and intentional (deliberate activities like hiking or gardening). Only incidental and intentional exposure showed a significant statistical link to improved diet quality .

The Mind-Body Connection

The mechanism behind this nature-diet link appears rooted in stress reduction and mental clarity. In interviews, people often described nature as a place that eased stress before it changed anything on the plate. Lower stress can reduce the urge to reach for comfort food, making room for more deliberate choices . One study participant explained how outdoor time shifted their relationship with food: "When I'm out in nature, when I'm occupying myself, when I'm doing something meaningful … I think my mind is less concerned about … easy ways to satisfy myself" .

The connection appears strongest among individuals reporting lower levels of depression, anxiety and stress. People with lower levels of depression, anxiety, and stress showed the strongest link between nature contact and better diet scores . When mental strain increased, the benefit weakened, suggesting green time helps most when people can fully absorb it .

Participants talked about how feeling connected to nature prompted them to eat more fruits and vegetables. Researchers confirmed these insights with survey data and found that spending time in nature increased people's connection to nature, and then connection to nature promoted a better quality and more sustainable diet .

Beyond Personal Health

The study tracked more than just individual nutrition—it also examined sustainable eating patterns that benefit the planet. The study tracked a sustainable diet—an eating pattern with lower environmental strain—and found that nature contact aligned with that pattern as well. This reflects a broader idea supported by the EAT-Lancet Commission, which shows that plant-heavy diets can ease pressure on land, water, and climate .

Four themes highlighted how interacting with nature may affect dietary intake: engaging with the natural world relaxes the mind, paving the way for healthier eating habits; pursuing health draws us toward nature and positively influences dietary choices; a deep connection to nature sparks a desire to nourish the body with more fruits and vegetables; and thoughtfully participating in the food system promotes healthier choices for personal and planetary health .

Practical Applications

One of the most practical insights is how ordinary the helpful exposure can be. It is not limited to hiking or spending long hours outdoors. Houseplants, a greener commute, or time in a yard can bring people into contact with living environments without turning health into a formal project . "This is finding your nearest park, your nearest green space or maybe spending time in your own backyard to promote your health" , said lead researcher Dahlia Stott.

Most participants were not frequent nature seekers, which made the findings harder to dismiss as a quirk of outdoor enthusiasts. More than half reported intentional time in green spaces less than once a week, yet the healthier eating link still appeared . This accessibility could make nature-based interventions particularly valuable for public health initiatives targeting dietary improvement.

As urban environments continue expanding and processed foods dominate the marketplace, these findings suggest that simple environmental changes—adding green spaces to neighborhoods or encouraging outdoor breaks—might serve as unexpected allies in promoting better nutrition. The research opens doors for healthcare providers and policymakers to consider nature access as a component of comprehensive wellness strategies.
