BackgroundSustainable dietary practices can help reduce greenhouse gas emissions and promote planetary health. The importance of investigating how to promote sustainable dietary practices is therefore crucial. Nature Relatedness measures an individual’s connection to nature and can predict environmental concern and stewardship. While emerging research has suggested those with a higher degree of Nature Relatedness report the intention to follow more sustainable dietary practices, the relationship between actual dietary intake and Nature Relatedness has yet to be fully explored. Therefore, the purpose of this pilot study was to assess the relationship between diet quality and Nature Relatedness. MethodsIn this cross-sectional study, participants across the United States completed the online survey from September to November 2023. Diet History Questionnaire II and Nature Relatedness scale were completed by the participants. Diet quality was assessed using the Healthy Eating Index (HEI)-2020 total and component scores. Nature Relatedness total and subscale scores were computed. Pearson and Spearman Rho correlation coefficients assessed associations between HEI-2020 and Nature Relatedness. Simple linear regression models examined the relationships between HEI-2020 total and component scores and Nature Relatedness (controlling for age, gender, race, and education). ResultsThree hundred adults completed the study. HEI-2020 total score was positively associated with Nature Relatedness (p < 0.001). Total fruit, total vegetable, green and beans, and refined grains component scores were positively associated with Nature Relatedness (p < 0.001). Nature Relatedness significantly predicted diet quality and total fruit, total vegetable, greens and beans, and moderation of refined grains consumption. ConclusionsThere are positive and significant relationships between diet quality, components of dietary intake that may promote planetary health, and Nature Relatedness. Our findings may be used to inform future research and nutrition intervention programs promoting personal and planetary health through nature-based interventions.
