Nutrition employability and graduate readiness:The Australian Working in Nutrition study

Background: Nutrition science graduates contribute to the nutrition workforce by bringing specialist knowledge and skills needed to address future food challenges. This study aims to provide a snapshot of the current employment landscape for nutrition science graduates in Australia and how well their degrees prepare them for employment. Method: A cross-sectional survey of Australian tertiary nutrition graduates was conducted to explore tertiary training, employment pathways and their perceived preparedness for practice. Results: This study included a final sample of 119 graduates from 17 Australian tertiary institutions. Almost two-thirds of respondents had completed further training. Most graduates (77%, n = 91) had worked in a food, nutrition science or health-related role after their degree; the most frequently cited employment settings were government or public health organisations; research, not-for-profit or nongovernment organisations; and the food industry. Work-integrated learning was identified as a key predictor of graduates working in a role that differed from their expectations as a student. The skill categories developed during nutrition training that were most valued in the workplace included nutrition and scientific knowledge, and professional and communication skills. Conclusions: This study offers first insights into the current employment landscape for nutrition graduates across Australia. Findings show that current nutrition science professionals are highly qualified and prepared to navigate the evolving demands of nutrition practice. Regular review of graduate employment will inform nutrition science curriculum to enable graduates to be well equipped in the face of dynamic practice settings.</p

Undergraduate Student Perspectives on Employability : A Mixed Methods Exploration of Nutrition Student Career Awareness, Confidence, and Preparedness

There is a growing need for nutrition graduates to fill diverse roles that will address emerging health priorities including community-based chronic disease prevention, personalised nutrition, digital health, and innovations in food and agriculture. Little is known about how well universities are preparing nutrition students to fill these roles. The aim of this study was to explore undergraduate nutrition students’ career awareness, confidence, and preparedness. A secondary aim was to explore their perspectives regarding employability initiatives within the university curriculum. A mixed methods approach was used, including semi-structured focus groups to gain in-depth insights and surveys to expand and diversify the study population, enhancing validity and transferability of the findings. Results of the focus groups were analysed thematically using an inductive approach. Initial themes informed the survey with closed questions analysed using descriptive statistics and open questions analysed thematically. Seven students participated in focus groups and 73 completed the survey. Common themes arising from the focus group and survey responses included a lack of awareness of roles available to nutritionists, lack of placement experience seen as a link to understanding what nutritionists do and getting that first job, and life experiences and personal circumstances influencing career pathways. Practical opportunities for nutrition students to develop their career awareness, confidence, and preparedness should be a key consideration in the design of the undergraduate nutrition curricula

Can Gut Microbiota Composition Predict Response to Dietary Treatments?

Dietary intervention is a challenge in clinical practice because of inter-individual variability in clinical response. Gut microbiota is mechanistically relevant for a number of disease states and consequently has been incorporated as a key variable in personalised nutrition models within the research context. This paper aims to review the evidence related to the predictive capacity of baseline microbiota for clinical response to dietary intervention in two specific health conditions, namely, obesity and irritable bowel syndrome (IBS). Clinical trials and larger predictive modelling studies were identified and critically evaluated. The findings reveal inconsistent evidence to support baseline microbiota as an accurate predictor of weight loss or glycaemic response in obesity, or as a predictor of symptom improvement in irritable bowel syndrome, in dietary intervention trials. Despite advancement in quantification methodologies, research in this area remains challenging and larger scale studies are needed until personalised nutrition is realistically achievable and can be translated to clinical practice.Peer reviewe

Food Intolerances

Food intolerances are estimated to affect up to 20% of the population but complete understanding of diagnosis and management is complicated, given presentation and non-immunological mechanisms associated vary greatly. This review aims to provide a scientific update on common food intolerances resulting in gastrointestinal and/or extra-intestinal symptoms. FODMAP sensitivity has strong evidence supporting its mechanisms of increased osmotic activity and fermentation with the resulting distention leading to symptoms in those with visceral hypersensitivity. For many of the other food intolerances reviewed including non-coeliac gluten/wheat sensitivity, food additives and bioactive food chemicals, the findings show that there is a shortage of reproducible well-designed double-blind, placebo-controlled studies, making understanding of the mechanisms, diagnosis and management difficult. Enzyme deficiencies have been proposed to result in other food sensitivities including low amine oxidase activity resulting in histamine intolerance and sucrase-isomaltase deficiency resulting in reduced tolerance to sugars and starch. Lack of reliable diagnostic biomarkers for all food intolerances result in an inability to target specific foods in the individual. As such, a trial-and-error approach is used, whereby suspected food constituents are reduced for a short-period and then re-challenged to assess response. Future studies should aim to identify biomarkers to predict response to dietary therapies

Intragastric fructose administration interacts with emotional state in homeostatic and hedonic brain regions

Background: Interoceptive properties of food may influence emotional state and its neural basis, as shown for fatty acids but remains unstudied for carbohydrates. Objectives: To study the effects of fructose and its interaction with sad emotion on brain activity in homeostatic and hedonic regions and investigate whether gut hormone responses can explain effects. Design: In 15 healthy subjects, brain activity for 40min after intragastric infusion of fructose (25g) or water was recorded using a cross-over pharmacological magnetic resonance imaging (phMRI) paradigm. Sad or neutral emotional states were induced by classical music and emotional facial expressions. Emotional state was assessed using the Self-Assessment Manikin. Blood samples were taken to assess gut hormone levels. Brain responses to fructose versus placebo, sad versus neutral emotion, and their interaction were analyzed over time in a single mask of a priori defined regions of interest at a voxel-level threshold of pFWEcorrected  <0.05. Effects on emotion and hormones were tested using linear mixed models. Results: No main effects of fructose, emotion, or fructose-by-emotion interaction on emotional ratings were observed. Main effects of fructose, emotion and aninteraction effect were found on brain activity (medulla, midbrain, hypothalamus, basal ganglia, anterior insula, orbitofrontal cortex, anterior cingulate cortex and amygdala). An increase in circulating GLP-1 after fructose in neutral emotion was abolished during sad emotion (fructose-by-emotion-by-time, p=0.041). Ghrelin levels were higher in sad emotion (time-by-emotion, p=0.037). Conclusions: Emotional state interacts with brain and endocrine responses to intragastric infusion of 25 g of fructose, however such an effect was not found at behavioral level.
