Sustainable 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.
In 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).
Three hundred adults completed the study. HEI-2020 total score was positively associated with Nature Relatedness ( < 0.001). Total fruit, total vegetable, green and beans, and refined grains component scores were positively associated with Nature Relatedness ( < 0.001). Nature Relatedness significantly predicted diet quality and total fruit, total vegetable, greens and beans, and moderation of refined grains consumption.
There 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.
可持续的饮食习惯有助于减少温室气体排放并促进地球健康。因此，研究如何推广可持续饮食习惯至关重要。与自然的关联度衡量个人与自然的联系，能够预测环境关注度和管理意识。虽然新兴研究表明，与自然关联度较高的人表示有意愿遵循更可持续的饮食习惯，但实际饮食摄入与自然关联度之间的关系尚未得到充分探索。因此，本试点研究的目的是评估饮食质量与自然关联度之间的关系。
在这项横断面研究中，美国各地参与者于2023年9月至11月完成在线调查。参与者完成了饮食历史问卷II和与自然关联度量表。使用健康饮食指数（HEI）-2020总分及各成分得分评估饮食质量。计算与自然关联度总分及各子量表得分。Pearson和Spearman Rho相关系数评估HEI-2020与自然关联度之间的关联。简单线性回归模型检验HEI-2020总分及各成分得分与自然关联度之间的关系（控制年龄、性别、种族和教育程度）。
300名成年人完成了该研究。HEI-2020总分与自然关联度呈正相关（<0.001）。水果总量、蔬菜总量、绿色蔬菜和豆类以及精制谷物成分得分与自然关联度呈正相关（<0.001）。自然关联度显著预测了饮食质量以及水果总量、蔬菜总量、绿色蔬菜和豆类，还有精制谷物消费的适度性。
饮食质量、可能促进地球健康的饮食摄入成分与自然关联度之间存在积极且显著的关系。我们的研究结果可用于为未来研究和营养干预项目提供信息，通过基于自然的干预措施促进个人和地球健康。
