Malnutrition linked to poor quality diets affects at least 2 billion people. Forests, as well as agricultural systems linked to trees, are key sources of dietary diversity in rural settings. In the present article, we develop conceptual links between diet diversity and forested landscape mosaics within the rural tropics. First, we summarize the state of knowledge regarding diets obtained from forests, trees, and agroforests. We then hypothesize how disturbed secondary forests, edge habitats, forest access, and landscape diversity can function in bolstering dietary diversity. Taken together, these ideas help us build a framework illuminating four pathways (direct, agroecological, energy, and market pathways) connecting forested landscapes to diet diversity. Finally, we offer recommendations to fill remaining knowledge gaps related to diet and forest cover monitoring. We argue that better evaluation of the role of land cover complexity will help avoid overly simplistic views of food security and, instead, uncover nutritional synergies with forest conservation and restoration.
与劣质饮食相关的营养不良影响着至少20亿人。森林以及与树木相关的农业系统是农村地区饮食多样性的关键来源。在本文中，我们阐述了农村热带地区饮食多样性与森林景观镶嵌体之间的概念联系。首先，我们总结了从森林、树木和农林复合系统获取的饮食的知识现状。然后，我们推测受干扰的次生林、边缘栖息地、森林可达性和景观多样性如何在增强饮食多样性方面发挥作用。综合起来，这些观点有助于我们构建一个框架，阐明将森林景观与饮食多样性联系起来的四条途径（直接途径、农业生态途径、能源途径和市场途径）。最后，我们提出建议以填补与饮食和森林覆盖监测相关的剩余知识空白。我们认为，更好地评估土地覆盖复杂性的作用将有助于避免对粮食安全的过度简单化看法，转而发现与森林保护和恢复相关的营养协同效应。
