A pathway to personal, population and planetary health for dietitians and nutrition professionals

Abstract Background Earth and all its inhabitants are threatened by a planetary crisis; including climate change, deforestation, biodiversity loss and pollution. Dietitians and nutrition professionals have a responsibility to lead transformational change in contemporary food and health systems to help mitigate this crisis. The study aims to develop a conceptual framework to support dietitians towards personal, population and planetary health. Methods Non‐empirical methods were used by the co‐researchers to explore and explain the application of an international framework ‘Next‐Generation Solutions to Address Adaptive Challenges in Dietetics Practice: The I + PSE Conceptual Framework for Action’. Results A non‐sequential pathway guide to personal, population and planetary health for nutrition professionals was developed including several key guiding principles of Agency, Action, Ascension, Alignment, Alliance and Allyship, and Advocacy and Activism. Each guiding principle features descriptors and descriptions to enhance dietitian and nutrition professional Agency (i.e. vision, self‐belief, confidence, strength and responsibility), Action (i.e. start, shift, translate, achieve and commit), Ascension (i.e. build, overcome, manage, challenge and progress), Alignment (i.e. leadership, transparency, diplomacy, values and systems), Alliance and Allyship (i.e. support, collaborate, represent, community and citizenship) and Advocacy and Activism (i.e. disrupt, co‐design, transform, empower and urgency). The framework and its descriptors support enhanced understanding and are modifiable and flexible in their application to guide the participation of dietitians and nutrition professionals in transformational change in personal, population and planetary health. This guide acknowledges that First Nations knowledge and customs are important to current and future work within this field. Conclusions Alongside the international body of work progressing in this field, this framework and visual guide will support dietitians and nutrition professionals to achieve urgent, transformational change in personal, population and planetary health

Genetic and Functional Diversity Help Explain Pathogenic, Weakly Pathogenic, and Commensal Lifestyles in the Genus Xanthomonas

The genus Xanthomonas has been primarily studied for pathogenic interactions with plants. However, besides host and tissue-specific pathogenic strains, this genus also comprises nonpathogenic strains isolated from a broad range of hosts, sometimes in association with pathogenic strains, and other environments, including rainwater. Based on their incapacity or limited capacity to cause symptoms on the host of isolation, nonpathogenic xanthomonads can be further characterized as commensal and weakly pathogenic. This study aimed to understand the diversity and evolution of nonpathogenic xanthomonads compared to their pathogenic counterparts based on their cooccurrence and phylogenetic relationship and to identify genomic traits that form the basis of a life history framework that groups xanthomonads by ecological strategies. We sequenced genomes of 83 strains spanning the genus phylogeny and identified eight novel species, indicating unexplored diversity. While some nonpathogenic species have experienced a recent loss of a type III secretion system, specifically the hrp2 cluster, we observed an apparent lack of association of the hrp2 cluster with lifestyles of diverse species. We performed association analysis on a large data set of 337 Xanthomonas strains to explain how xanthomonads may have established association with the plants across the continuum of lifestyles from commensals to weak pathogens to pathogens. Presence of distinct transcriptional regulators, distinct nutrient utilization and assimilation genes, transcriptional regulators, and chemotaxis genes may explain lifestyle-specific adaptations of xanthomonads

A Pathway to Planetary Health for Dietitians and Nutrition Professionals

A non-sequential pathway guide to Population, Personal and Planetary Health for Dietitians and Nutrition Professionals was developed including several key guiding principles of Agency, Action, Ascension, Alignment, Advocacy and Activism and Alliance and Allyship.

We recognise that further collaboration and future work relating to planetary health and sustainability with First Nations and, in Australia, Aboriginal and Torres Strait Islander people is vital, and we propose to advance this body of work by supporting and collaborating with First Nations people in the work they are leading to support our planetary health and ensuring sustainable food sources.   We acknowledge Brenna Quinlan of Illustrations with a Purpose for her consultancy to develop Figure 1; the Pathway figure which features a sweet pea vine.  This version supercedes the previous FigShare published version but either can be used.</p
