Programmatic assessment has gained momentum in health professions education for its potential to address challenges in competency-based education. Yet, little is known about how to create the cultural and systemic changes needed for sector-wide enactment. This study used realist evaluation to develop and refine theory about how, why, and in what contexts a community of practice for Australian and New Zealand dietetic educators contributed to advancing programmatic assessment in dietetics higher education. Programme theory highlights the influence of committed, cross-institutional members, supported by an experienced and inclusive facilitator, on both the functioning and outcomes of the community of practice. Within …
Exploring The Dairy Milk Matrix Beyond Isolated Nutrients—A Narrative Review, Therese A. O’Sullivan, Analise Nicholl
Exploring The Dairy Milk Matrix Beyond Isolated Nutrients—A Narrative Review, Therese A. O’Sullivan, Analise Nicholl
Research outputs 2022 to 2026
The concept of the food matrix considers individual components along with how they are structured, interact, and are modified during processing. There is increasing interest around the health effects of individual nutrients versus whole foods, creating a need to better understand how the matrix may influence health outcomes. This narrative review explores the dairy milk matrix and compares health effects with those of isolated components, with additional comparisons to plant-based milk alternatives. Comparative evidence suggests that while calcium from food and supplements generally has similar effects (depending on the form of the supplemental calcium), consumption of food-based sources such as …

To accommodate population growth, Australian cities are becoming denser, with more Australians living in apartments. However, there is little understanding of whether this shift towards apartment living raises any potential short- and long-term implications for dietary health. Using an Australian nationally representative household survey, this cross-sectional study compared meal-purchasing frequency and fruit and vegetable intake by dwelling type, apartment block height, and number of bedrooms in the apartment. Adjusted mean differences were derived from linear regressions, adjusting for socio-demographic characteristics. Apartment residents purchased 0.72 more meals out each week than house residents (p < 0.001, 95% CI [0.599,0.831]) and consumed 0.10 fewer daily serves of vegetables (p = 0.002, 95% CI [0.038,0.163]). Among apartment residents, those in high-rise blocks purchased 0.80 more meals out each week than low-rise residents (p = 0.012, 95% CI [0.250,1.348]), and residents of one-bedroom or studio apartments ate 0.25 fewer serves of fruit per day than residents in apartments with at least three bedrooms (p = 0.003, 95% CI [0.038,0.163]). These findings provide important evidence to inform policy and targeted interventions that promote healthy food behaviours in apartment-living populations.

Food is more than its nutritional components. It brings people together, and connects us to family, culture, and heritage. The development of eating habits and relationships with food begins in infancy and continues across the lifespan. Echoing the theme of Metallica’s 72 Seasons, which was being toured in Australia when this work was presented, experiences during the early years may shape later patterns of behaviour and identity. This can include mindsets around food and eating. This review aims to explore how early life parent/caregiver feeding practices may impact this development of children’s eating behaviours. A respectful and responsive approach to …

Research outputs 2022 to 2026
Purpose: A growing body of evidence suggests diets rich in flavonoids may protect against metabolic-dysfunction associated steatotic liver disease (MASLD) development and progression. As the gut microbiome is important in the biotransformation of flavonoids to their constituent bioactive metabolites, studies on the potential mediating role of the gut microbiome in the association between dietary flavonoid intakes and MASLD are warranted but lacking. Thus, this study aims to examine the associations between a diet rich in flavonoids and MASLD, and assess the potential mediating role of the gut microbiome. Methods: In a cross-sectional analysis (n = 531), using the FlavoDiet score …

Vitamin K refers to a group of lipid-soluble vitamins that exist in two natural isoforms; phylloquinone (PK, vitamin K1) and menaquinones (MKs, vitamin K2). Phylloquinone, the primary dietary source, is found abundantly in green vegetables and plant oils. Menaquinones (MK-4 through MK-13) are synthesized by anaerobic bacteria and may be obtained through the diet from fermented foods and animal products (e.g., meats, dairy and eggs). Originally recognized for its role in blood coagulation, vitamin K is an essential cofactor for the posttranslational carboxylation of vitamin K-dependent proteins (VKDPs), which are implicated in various physiological processes including; blood coagulation, calcium homeostasis, …

Sorghum (Sorghum bicolor L.) is a member of the Poaceae family and is the fifth most important crop globally. Sorghum grains (SGs) are rich in health-promoting macro- and micronutrients and phytochemicals. SGs are commonly consumed as food or as ingredients in food, especially in African countries. Therefore, food products such as ogi, bread and flour have been and are still being developed from SGs to provide nutritional and health benefits. However, the nutritional and prebiotic potential of SGs, especially the pigment pericarps, has not been fully exploited. This review describes micronutrients in different varieties of sorghum and the health benefits …

Aims: Higher cruciferous vegetable (e.g., broccoli) intake is associated with lower risk of type 2 diabetes and cardiovascular disease, but limited causal evidence exists. We investigated if cruciferous vegetable intake improved glycaemic control compared to root/squash vegetables in non-diabetic adults with elevated blood pressure. Materials and Methods: This randomized, controlled, crossover trial consisted of two 2-week dietary interventions (300 g/day cruciferous [active] and root/squash [control] soups with standardized lunch/dinner meals) separated by a 2-week washout. Participants were blinded to the intervention allocation. Glycaemic measures were a pre-specified secondary outcome. Flash glucose monitoring measured interstitial glucose every 15-min throughout both interventions. …

Aims: Concept-based approaches to curricula have been proposed as a solution to this issue, and 56 concepts have been proposed for dietetics curricula. This study aimed to develop a framework for a dietetic concept-based curriculum. Methods: A pragmatic approach was employed by a team of nine experienced Australian dietetic educators. Iterative processes of idea generation, reflection, group discussion, and consensus formation were applied by seven of the academics in a two-day face-to-face workshop and four online meetings to further develop the 56 curriculum concepts previously identified for dietetics by Tweedie et al. The discussions were supported by document analysis and …

Inorganic dietary nitrate, metabolized through an endogenous pathway involving nitrate reducing bacteria, improves cardiovascular health, but its effects on the oral and intestinal microbiomes of older adults with treated hypertension are unknown. Our study investigated the effects of nitrate from beetroot juice on the oral and intestinal microbiomes of this population. A randomized, double-blind, placebo-controlled crossover trial was conducted with 15 participants (age range: 56–71 years), who consumed nitrate-rich or nitrate-depleted (placebo) beetroot juice for 4 weeks. The oral microbiome analysis revealed an increase in Neisseria and a decrease in Veillonella relative abundance (for both, PERMANOVA p < 0.001), with no significant changes in the intestinal microbiome composition. Our findings suggest that an increased dietary nitrate intake from a vegetable source may selectively modulate the oral microbiome and promote an increased abundance of nitrate-reducing species, which was previously associated with improved cardiovascular health outcomes.

Higher habitual intakes of dietary flavonoids have been linked with a lower risk of all-cause mortality and major chronic disease. Yet, the contribution of diversity of flavonoid intake to health outcomes remains to be investigated. Here, using a cohort of 124,805 UK Biobank participants, we show that participants who consumed the widest diversity of dietary flavonoids, flavonoid-rich foods and/or specific flavonoid subclasses had a 6–20% significantly lower risk of all-cause mortality and incidence of cardiovascular disease, type 2 diabetes, cancer, respiratory disease and neurodegenerative disease. Furthermore, we report that both quantity and diversity of flavonoids are independent predictors of mortality …
