Career Summary

Biography

Dr Georgina Williams is a postdoctoral researcher in diet and gastroenterology, working in the Centre for Research Excellence in Digestive Health. Her current research examines the role of the diet in gastrointestinal disease, with a focus on diet-microbiota interactions.

Georgina was awarded her PhD in 2022 from the University of Wollongong. This work explored the relationship between diet-microbiota interactions and metabolic health outcomes, including non-alcoholic fatty liver disease. This research strengthened evidence pertaining to the role of dietary fibre, particularly from whole grains, in modulating the gut microbiome with potential for health benefits. A key finding of this research was the realisation of limitations in current diet-microbiota study design which has hindered research outcome translation, resulting in uncertainty in both consumer and dietitians. This research sparked Georgina’s interest in bettering research methods in diet-microbiota studies to ensure outcomes are useful for translation to nutrition practice. At present this work is focussed on how diet-microbiota interactions can be in utilised to improve dietary management of gastrointestinal disease and disorders. This includes enhancing dietary assessment of microbiota accessible nutrients.

Georgina completed a Bachelor of Nutrition and Dietetics at the University of Wollongong in 2017 and has worked as a dietitian across both public and private sectors. Georgina is passionate about the interaction between clinical practice and research outcomes and is focused on ensuring both areas inform the other, in order to promote individualised, evidence based practice to better health.

Aims: This study aimed to explore dietitians' perspectives on the evidence surrounding the relationship between diet and ¿gut health¿ and the current and emerging role of dietetics practice in this area. Methods: A qualitative descriptive methodology was used. Online semi-structured interviews were conducted with Australian dietitians, focused on the perspectives related to gut health management in dietetics practice. Inductive thematic analysis was employed, commencing with initial coding by two researchers, and further coding leading to development of emergent themes. Divergent data were discussed and considered in analysis. Results: Fourteen interviews were conducted (2 males, 12 females). An overarching theme identified that current evidence is insufficient to direct dietetics practice change regarding gut health. Six subthemes on dietetics practice in ¿gut health¿ emerged including (a) practice is multifaceted, (b) current practice aligns with dietary guidelines, (c) symptom management remains the primary concern, (d) evidence-based information is sought, (e) translational evidence is required for practice change and (f) there is a role for dietetics in gut health research and translation. Conclusions: Dietitians do not appear confident in their practice regarding gut microbiome-related management and recognise there is currently limited translatable research to inform practice. Evidence to date suggests that recommendations for positive gut health do not differ substantially from Australian Dietary Guidelines. Dietitians will need additional education if further evidence emerges, however they demonstrated a strong commitment to evidence-based practice.

Aims: To explore consumer perceptions regarding dietary behaviours related to the gut microbiome, to assist in effective translation of research to practice. Methods: Online focus groups were conducted (adults with no formal medical or nutrition training). Semi-structured open-ended questioning explored perspectives related to gut health and dietary behaviours. A qualitative descriptive analysis approach was undertaken in duplicate. Results: Fourteen focus groups were conducted (n¿=¿38, 15 males, 23 females). Four overarching themes regarding consumer perceptions were identified. These were (a) gut health equates with wellbeing, (b) there are divergent perceptions of how diet influences gut health, (c) interest in scientific evidence does not necessarily influence dietary behaviour and (d) gastrointestinal symptoms influence dietary behaviour. Conclusions: Consumers are interested in gut health and understand that diet may be important. Given that current literature regarding diet and gut health does not differ from dietary guidelines, consumer interest may provide a timely slant to promote longstanding guidelines. Consumer education to limit scepticism around government messaging, including utilisation of social media by nutrition professionals, may be key to improving adherence to guidelines.
