Sustainable Eating Mediates the Relationship Between Physical Activity and Love and Care for Nature
This study of 1,230 students aged 9–16 reveals that sustainable eating partially mediates the positive relationship between physical activity and love and care for nature, highlighting the value of integrated planetary health interventions.

The planet and the people living on it are deeply connected, a concept scientists call planetary health. This field recognizes that the well-being of human beings cannot be separated from the health of the natural world. When the environment suffers, human health often suffers too, and the choices people make every day play a huge role in this relationship. Two of the most powerful daily choices involve how we move our bodies and what we put on our plates. Moving regularly, known as physical activity, is essential for keeping the body strong and the mind clear. Eating in a way that respects the limits of the earth, called sustainable eating, means choosing foods that do not harm the environment, such as eating more plants and less meat, or buying food that is grown nearby. Alongside these actions is a feeling often described as love and care for nature, which is the emotional bond a person feels toward the wild world. Researchers have long suspected that these three things—moving, eating well, and caring for the earth—might be linked, but it has been unclear exactly how they influence one another, especially in young people who are still forming their lifelong habits.
A team of researchers from the University of Thessaly in Greece set out to untangle these connections among students aged nine to sixteen. They gathered a large group of 1,230 students from schools across central Greece to answer a specific question: does the way young people eat help explain why those who are more active also tend to care more deeply for nature? To find out, the students filled out questionnaires about their weekly exercise habits, their food choices, and their feelings toward the natural world. The researchers looked for a pattern where being active might lead to better food choices, which in turn might strengthen a child's emotional connection to the environment.
The study found that the students who reported being physically active on more days of the week were also more likely to report making sustainable food choices. Furthermore, those who made these sustainable food choices reported having a stronger sense of love and care for nature. The data showed that sustainable eating acts as a bridge between the two. In other words, while being active does have a direct, small link to caring for nature, a significant part of that connection happens because active young people tend to eat in ways that are better for the planet, and this way of eating helps them feel more connected to the natural world. The researchers described this as a partial mediation, meaning that while exercise and nature care are directly related, the path through food choices explains a meaningful portion of that relationship.
This finding suggests that these healthy behaviors do not exist in isolation but rather reinforce one another. When a young person is active, they may become more aware of their body and their health, which can extend to the food they choose. Choosing foods that are good for the earth, such as limiting red meat or buying local products, then seems to deepen their emotional appreciation for the natural world. The study did not prove that one causes the other in a strict sense, as the research was conducted at a single point in time, but it provides strong evidence that these habits cluster together. The authors noted that the effect was modest, indicating that while this link is real, many other factors also shape how a child feels about nature.
The implications of this discovery point toward a more integrated approach to helping young people. Instead of treating exercise, nutrition, and environmental education as separate subjects, the researchers suggest that combining them could be more effective. Programs that encourage outdoor activity while also teaching about sustainable food choices might help build a generation that is both physically healthy and deeply committed to protecting the planet. By understanding that these behaviors are linked, educators and parents can see that promoting one healthy habit might naturally support the others, creating a cycle of well-being for both the individual and the earth they share.
