Perceived nutrition needs of people experiencing disadvantage in utilizing support services: An Australian case study.

Individuals experiencing socio-economic disadvantage face higher rates of food insecurity and health disparities. This study explored the perceptions, attitudes, and knowledge of individuals providing nutrition services, and users of these services, to identify nutrition needs and inform potential strategies for addressing diet-related health inequities. Semi-structured interviews were conducted utilizing a phenomenological approach to explore lived experiences, beliefs, and perceptions influencing nutrition-related health. Key themes were derived by consensus among researchers using inductive thematic analysis. Twenty-two interviews were completed, which identified five themes. "Budgetary Constraints" was found to have a pervasive impact on all nutrition-related services. Secondly, diverse "Individual Clientele" was found to influence three overlapping themes pertaining to opportunities and limitations for "Knowledge and Skills," "Services, Resources and Staff," and the "Systems and Food Environment." Budgets directly impact the availability of services, resources, food provision, sustainability, and educational opportunities for staff, volunteers and service users. A live-in environment offers a platform to implement and evaluate targeted interventions to inform and enhance nutrition-related support services. Future interventions should address individual and systemic influences, prioritizing client-informed, cost-effective, sustainable capacity building for clients and staff. Recommendations for systemic and environmental influences include formalized staff training, peer-mentoring systems, and increasing client autonomy. This has the potential to improve food security for residents following their transition into independent living. Charitable system limitations underscore the need for broader systemic change, informed policymaking, and government intervention to effectively address the root causes of food insecurity and diet-related health inequities.

Advancing the decadal plan for the science of nutrition: Progressing a framework for implementation.

AIMS: In 2019, the Australian Academy of Science in collaboration with the nutrition community published the decadal plan for the science of nutrition. This article aims to review progress towards each of its pillar goals (societal determinants, nutrition mechanisms, precision and personalised nutrition, and education and training) and two enabling platforms (a national data capability and a trusted voice for nutrition science), prioritise actions, and conceptualise program logic implementation models. This process also brought together public health nutrition researchers to reflect on societal determinants of health, and advise how the next 5 years of the decadal plan could reflect contemporary issues. METHODS: Two engagement events, in 2023, brought together experienced and mid- and early-career nutrition professionals for co-creation of implementation logic models. RESULTS: One hundred and nine early and mid-career professionals were involved. A revised model for the decadal plan pillars emerged from synthesis of all logic models. This new model integrated the precision and personalised nutrition pillar with nutrition mechanisms pillar. These combined pillars build towards the national data capability enabling platform and created new cross-cutting themes for education and training. The need arose for greater focus on respectful engagement with Aboriginal and Torres Strait Islander communities and sustained effort to build cross-disciplinary collaboration to realise the plan's societal determinants goals. A new alliance for nutrition science is proposed to become a unified advocacy voice and build trust in nutrition professionals. CONCLUSIONS: A programmatic approach provides a road map for implementing the decadal plan for the final 5 years.

Individuals' perceptions and expectations of nutrition care provided by doctors in Australia: A focus group study.

BACKGROUND AND OBJECTIVES: Doctors are well placed to facilitate nutrition care to support dietary improvements due, in part, to their regular contact with their patients. Limited literature exists which explores the perspective of patients regarding the nutrition care provided by medical professionals across the continuum of care. This article explores the perspective of patients regarding perceptions of nutrition advice and care received from doctors and expectations of this care, including key skills and attributes the patients perceive as important. METHOD: Six online focus groups were conducted with Australian service users (n=32). RESULTS: Framework analysis identified four key themes: perceptions of doctors' role in nutrition care, expectations and experiences; the importance of individualised care; barriers and enablers to nutrition care; and topics, skills and attributes perceived as important in nutrition care. DISCUSSION: Patients have a desire for individualised and collaborative nutrition care but experienced systemic barriers in practice.

Aligning front-of-pack labelling with dietary guidelines: including whole grains in the health star rating.

PURPOSE: Front-of-pack labelling systems, such as the Health Star Rating (HSR), aim to aid healthy consumer dietary choices and complement national dietary guidelines. Dietary guidelines aim to be holistic by extending beyond the individual nutrients of food, including other food components that indicate diet quality, including whole grains. We aimed to test the feasibility of including whole grains in the HSR algorithm, to better inform dietary guidance in Australia coherent with existing dietary guidelines. METHODS: We assigned whole-grain points as a favourable component of the HSR based on the whole-grain content of foods. We compared the original, and three modified HSR algorithms (including altered thresholds for star ratings) using independent-samples median tests. Finally, we used Spearman's correlation to measure the strength of association between an item's nutritional composition (all components of the HSR algorithm including all favourable and unfavourable components) and their HSR using each algorithm. RESULTS: Up to 10 points were added for products with ≥ 50% whole-grain content, with no points for products with < 25%. Adjusting the HSR score cut-off by 3 points for grain products created the greatest difference in median HSR between refined and whole-grain items (up to 2 stars difference), compared to the original algorithm (a maximum of 1 star). CONCLUSIONS: The addition of whole grains to the HSR algorithm improved the differentiation of refined and whole-grain items, and therefore better aligned with dietary guidelines. Holistic approaches to food guidance systems are required to provide consistent messaging and inform positive food choices.

Excluding whole grain-containing foods from the Nova ultraprocessed food category: a cross-sectional analysis of the impact on associations with cardiometabolic risk measures.

BACKGROUND: Whole grain (WG) consumption is linked with a reduced risk of chronic disease. However, the recommendations of the Nova classification system tend to contradict this evidence as high WG-containing foods, such as bread and cereals, are considered ultraprocessed, and intake is discouraged. OBJECTIVES: This study aimed to explore associations of cardiometabolic risk measures with ultraprocessed food (UPF) intake as classified by Nova compared with when foods with ≥25% and ≥50% WG are removed from the Nova UPF category. METHODS: A cross-sectional analysis of the 2015-18 National Health and Nutrition Examination Survey. Nova was used to identify UPFs, and the WG Initiative's definition of a WG food and front-of-pack labeling requirements was used to identify high WG foods. Regression models were used to explore impacts on the association of UPF intake (quintiles) and cardiometabolic risk measures when high WG foods were excluded from the Nova UPF category. RESULTS: Participants in the highest quintile of UPF intake had significantly higher weight [83.6 kg (0.8)], BMI (in kg/m2) [30.6 (0.3)], waist circumference [103.1 cm (0.6)], and weight-to-height ratio [0.63 (0.003)] compared to those in the lowest quintile (P < 0.0001 for all). The same was found when foods with ≥25% and ≥50% WG were removed. Positive associations for C-reactive protein were found when ≥25% and ≥50% WG-containing foods were removed only [2.32 mg/L (0.1), P = 0.0209; 2.37 mg/L (0.1), P = 0.0179, respectively]. Participants in the highest quintile had significantly lower total cholesterol after adjustment when foods with ≥50% WG were removed [4.98 mmol/L (0.04), P = 0.0292]. Adjusted R2 values remained relatively unchanged across each approach for all outcomes. CONCLUSIONS: Foods high in WG may not significantly contribute to the deleterious associations previously observed between UPF intake and cardiometabolic risk factors. Consideration of their contribution to healthful dietary patterns and diet quality in the United States population should be made prior to the endorsement of Nova.

Criterion validation of nutrient profiling systems: a systematic review and meta-analysis.

BACKGROUND: Nutrient profiling systems (NPSs) use algorithms to evaluate the nutritional quality of foods and beverages. Criterion validation, which assesses the relationship between consuming foods rated as healthier by the NPS and objective measures of health, is essential to ensure the accuracy of NPSs. OBJECTIVE: We examined and compared NPSs that have undergone criterion validity testing in relation to diet-related disease risk and risk markers. METHODS: Academic databases were searched for prospective cohort and cross-sectional studies published before November, 2022. NPSs were eligible if they incorporated multiple nutrients or food components using an algorithm to determine an overall summary indicator (e.g., a score or rank) for individual foods. Studies were included if they assessed the criterion validity of an eligible NPS. Validation evidence was first summarized in narrative form by NPS, with random effects meta-analysis where ≥2 prospective cohort studies assessed the same NPS and outcomes. RESULTS: Of 4519 publications identified, 29 describing 9 NPSs were included in the review. The Nutri-Score NPS was assessed as having substantial criterion validation evidence. Highest compared with lowest diet quality as defined by the Nutri-Score was associated with significantly lower risk of cardiovascular disease (hazard ratio [HR]: 0.74; 95% confidence interval [CI]: 0.59, 0.93; n = 6), cancer (HR: 0.75; 95% CI: 0.59, 0.94; n = 5), all-cause mortality (HR: 0.74; 95% CI; 0.59, 0.91; n = 4) and change in body mass index (HR: 0.68; 95% CI: 0.50, 0.92; n = 3). The Food Standards Agency NPS, Health Star Rating, Nutrient Profiling Scoring Criterion, Food Compass, Overall Nutrition Quality Index, and the Nutrient-Rich Food Index were determined as having intermediate criterion validation evidence. Two other NPSs were determined as having limited criterion validation evidence. CONCLUSIONS: We found limited criterion validation studies compared with the number of NPSs estimated to exist. Greater emphasis on conducting and reporting on criterion validation studies across varied contexts may improve the confidence in existing NPSs.

Recruitment, retention, and experiences of Australian male dietitians: A cross-sectional online survey.

AIM: Male dietitians are under-represented in the global dietetics workforce, including in Australia. This study explores Australian males' experiences as dietitians in the Australian workforce, with the aim to identify influences that initially attracted them to dietetics, as well as barriers that may affect their decision to stay in or leave the profession. METHODS: A cross-sectional, semi-quantitative web-based survey was distributed to male dietitians using purposive, snowball sampling. Closed and open-ended questions were included. Descriptive statistics were generated, and content analysis of free-text responses identified major themes. RESULTS: Seventy-one respondents opened the survey link, of which 65 respondents attempted the survey. Fifty-four (83.1%) respondents agreed that dietetics is female-dominated. An interest in food and nutrition was the most reported reason for studying dietetics (73.8%). Of the 55 respondents who were not intending to retire in the next 5 years, 15 (27.3%) stated they were somewhat or extremely likely to leave the profession of dietetics. Respondents identified issues that impacted their experiences as a male dietitian, including gender differences, a lack of male role models, barriers to career progression/employment, and perceptions of a lack of respect and impact within healthcare. CONCLUSIONS: Australian male dietitians perceive systemic, social, and personal factors that have influenced their career experiences. Greater exposure to prominent male role models may be self-perpetuating in improving male dietitian recruitment and eventually, retention. A multi-pronged approach is needed to improve the rate of recruitment of male dietitians, with a role for tertiary education providers and peak dietetics bodies.

The Effect of Non-Oil Seed Legume Intake on Blood Pressure: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

Hypertension is a primary modifiable risk factor for CVD, whereby even small reductions in blood pressure (BP) can decrease risk for CVD events. Modification of dietary patterns is an established, nonpharmacologic approach for the prevention and management of hypertension. Legumes are a prevailing component of dietary patterns associated with lower BP in observational research, but there is a need to understand the effects of legume consumption on BP. This study aimed to synthesize evidence from randomized controlled trials (RCTs) for the effects of non-oil seed legume consumption on systolic blood pressure (SBP) and diastolic blood pressure (DBP) (PROSPERO registration: CRD42021237732). We searched CINAHL, Cochrane, Medline, and PubMed scientific databases from inception through November 2022. A random-effects meta-analysis was conducted to assess the mean differences (MDs) for each outcome variable between legume-based and comparator diets. This review included 16 RCTs and 1092 participants. Studies ranged in duration (4-52 wk), participant age (17-75 y), and weekly legume dose (450-3150 g) in whole or powdered form. No significant overall effect between legume consumption and BP amelioration was observed in the meta-analysis (SBP-MD: -1.06 mm Hg; 95% CI: -2.57, 0.4410 mm Hg; I2 = 45%; DBP-MD: -0.48 mm Hg; 95% CI: -1.06, 0.10 mm Hg; I2 = 0%). The certainty of evidence was determined as low for SBP and DBP. Significant subgroup differences in SBP were found when studies were grouped according to participant BMI, with SBP reduction found for participants with overweight/obese BMI (MD -2.79 mm Hg, 95% CI: -4.68, -0.90 mm Hg). There is a need for large, high-quality trials to clearly define the benefits and mechanisms of legume consumption in BP management. Consideration of the relevance in individuals with obesity, overweight, and hypertension may also be warranted. This trial was registered at PROSPERO as CRD42021237732.

Dietitians' perspectives on the role of dietetics practice in 'gut 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.

Gut health, the microbiome and dietary choices: An exploration of consumer perspectives.

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.

ATTITUDES, WORK ROLES AND BARRIERS TO NUTRITION CARE - INTERVIEWS WITH AUSTRALIAN AND UK-BASED MEDICAL DOCTORS.

BACKGROUND: Poor diet is implicated in multiple chronic diseases. Although doctors may be well placed to facilitate nutrition care, nutrition remains a low priority in medical education internationally. Consensus is required on nutrition competencies as a benchmark for education with a regulatory framework to ensure implementation. The aim of this qualitative study was to explore work roles, attitudes, barriers and enablers in the delivery of nutrition care among a cohort of Australian and UK doctors. METHOD: Semi-structured interviews were conducted with primary care doctors/general practitioners (n = 14) and medical specialists (n = 8) based in Australia and the United Kingdom to explore work roles, attitudes, barriers and enablers in the delivery of nutrition care. RESULTS: Framework analysis identified five key themes: (1) knowledge and skills in nutrition to support medical nutrition care, (2) the delivery of nutrition education, (3) multidisciplinary and interdisciplinary care, (4) systemic barriers and facilitators to care and (5) the need for a paradigm shift. Participants acknowledged nutrition as an important component of medical care but recognised they are currently ill-equipped to support such care, identifying limitations to the systems supporting integrated care. Participants identified that nutrition sits within both a health promotion and medical/treatment model, but they currently work only within the latter. CONCLUSION: Participants highlighted a lack of knowledge and training regarding nutrition, without which change is not possible. Efforts to improve the nutrition capacity of the medical workforce must be matched by increased investments in primary prevention, including nutrition - a paradigm shift from the medical model.

Knowledge, Messaging, and Selection of Whole-Grain Foods: Consumer and Food Industry Perspectives.

OBJECTIVE: To explore whole-grain food definitions in labeling and relevance to consumers and the food industry. DESIGN: Semistructured focus groups and interviews. SETTING: Online. PARTICIPANTS: Consumers (n = 43) aged ≥ 18 years currently purchasing/consuming grain foods. Food industry participants (n = 17) currently/recently employed within grain food companies. PHENOMENON OF INTEREST: Impact of using whole-grain food definitions in labeling. ANALYSIS: Inductive thematic analysis. RESULTS: Six major themes included: consumer knowledge and understanding of whole-grain foods; factors affecting consumer grain food choices; consumer skepticism of labeling; consumer preferences toward whole-grain labeling; acceptability and feasibility of whole-grain food definitions in the food industry; and food innovation/reformulation. For the food industry, definitions impact feasibility, food innovation, and reformulation. Skepticism affected consumer knowledge and understanding, impacting grain food choice and their preference regarding whole-grain labeling. Consumers preferred whole grain in the name of a food and placing the percent of whole grain on the front-of-pack. CONCLUSIONS AND IMPLICATIONS: Our findings suggest that definitions and regulations, consumer education, and strategies addressing factors influencing consumer choice are needed to improve population whole-grain intakes. Future research may consider formal regulation and implementation of standardized whole-grain food definitions in labeling and explore the subsequent impact on consumer choice and whole-grain intake.

Nutrition programmes for individuals living with disadvantage in supported residential settings: a scoping review.

OBJECTIVE: Health inequities such as chronic disease are significantly higher among individuals living with disadvantage compared with the general population and many are reported to be attributable to preventable dietary risk factors. This study provides an overview of the current nutrition interventions for individuals living with extreme disadvantage, in supported residential settings, to develop insights into the development and implementation of policies and practices to promote long-term nutritional health and well-being. DESIGN: A scoping review searched Scopus, ProQuest, CINAHL Plus, MEDLINE, and Web of Science databases using the terms 'resident', 'nutrition', 'disadvantage', 'intervention' and their synonyms, with particular emphasis on interventions in residential settings. SETTING: Residential services providing nutrition provision and support. PARTICIPANTS: People experiencing extreme disadvantage. RESULTS: From 5262 articles, seven were included in final synthesis. Most interventions focused on building food literacy knowledge and skills. Study designs and outcome measures varied; however, all reported descriptive improvements in behaviour and motivation. In addition to food literacy, it was suggested that interventions need to address behaviour and motivations, programme sustainability, long-term social, physical and economic barriers and provide support for participants during transition into independent living. Socio-economic issues remain key barriers to long-term health and well-being. CONCLUSIONS: In addition to food literacy education, future research and interventions should consider utilising an academic-community partnership, addressing nutrition-related mental health challenges, motivation and behaviour change and a phased approach to improve support for individuals transitioning into independent living.

A qualitative exploration of the future of nutrition and dietetics in Australia and New Zealand: Implications for the workforce.

AIM: We aimed to explore the future roles of nutrition and dietetics professionals, and what capabilities the workforce would need to fulfil these roles. METHOD: A qualitative interpretive approach was employed. We conducted individual interviews with nutrition and non-nutrition thought leaders external to the profession. In addition, we conducted focus groups with experts within the nutrition and dietetics profession, academic dietetics educators and students/recent nutrition and dietetics graduates (total sample n = 68). Key nutrition-related issues and challenges, drivers for change and potential future roles of the profession were explored. Data were analysed using a team-based thematic analysis approach. RESULTS: Future roles of nutrition and dietetics professionals were described as food aficionados, diet optimisers, knowledge translators, equity champions, systems navigators and food systems activists, change makers, activists and disruptors. In addition, science was identified as a uniting framework underpinning the professions. An additional 16 critical capabilities were considered to underpin practice. CONCLUSION: The results demonstrated that the current and future needs for workforce education and development need to address the impact of climate change, growing inequities, the democratisation of knowledge and the disruption of health and food systems. Education providers, regulators, professional associations and citizens need to work together to realise roles that will deliver on better health for all.

Fortification of grain foods and NOVA: the potential for altered nutrient intakes while avoiding ultra-processed foods.

PURPOSE: NOVA is a food classification system describing a hierarchy from minimally processed to ultra-processed foods (UPF). Research has associated intake of UPF with chronic diseases. In Australia, the primary sources of grains, both refined and whole, are breads and breakfast cereals, which are typically fortified. Most are classified as UPF, yet are recommended core foods according to the Australian Dietary Guidelines (ADG). This research aimed to identify if avoidance of ultra-processed grain foods would alter nutrient intakes in an Australian population and whether sample diets using substitute (non-UPF) foods would be likely to meet nutrient requirements. METHODS: Quantitative analysis of usual nutrient intake from the National Nutrition and Physical Activity Survey 2011-12 (n = 12,153) for all foods including and excluding UPF. Dietary modelling examined the nutritional adequacy of sample diets aligned with the ADG and another containing replacements for UPF. We particularly focused on grain foods and meeting whole-grain intake targets. RESULTS: There was a significant decrease (all p < 0.05) in modelled intake of key nutrients when UPF were excluded, specifically, thiamin, folate and iodine, as substitutions are rarely fortified. Diets with no UPF, where substitutes are carefully chosen, have the potential to meet Nutrient Reference Values, but deviation from customary food choices may mean adoption of substitutes is unlikely. CONCLUSIONS: Exclusion of UPF may result in lowered intakes of key nutrients of particular concern for at risk groups (including women of child-bearing age), negating gains made by public health policy of fortification. Substitutions may not be realistic in these at-risk populations.

Aligning nutrient profiling with dietary guidelines: modifying the Nutri-Score algorithm to include whole grains.

PURPOSE: Whole grains, generally recognised as healthy choices, are not included in most nutrient profiling systems. We tested modifications to the Nutri-Score algorithm to determine whether including whole grains would provide an improved measure of food, and overall diet quality. METHODS: The whole-grain content of food, with a minimum cut-point of 25%, was added to the algorithm, following similar methods used to score other health-promoting components such as fibre. We applied and compared the original and the modified Nutri-Score to food composition and dietary intake data from Australia, France, the United Kingdom, and the United States. RESULTS: At the food level, correlations between whole-grain content and food nutritional score were strengthened using the modified algorithm in Australian data, but less so for the other countries. Improvements were greater in grain-specific food groups. The largest shift in Nutri-Score class was from B to A (best score). At the dietary intake level, whole-diet nutritional scores for individuals were calculated and compared against population-specific diet-quality scores. With modifications, correlations with diet-quality scores were improved slightly, suggesting that the modified score better aligns with national dietary guidelines. An inverse linear relationship between whole-diet nutritional score and whole-grain intake was evident, particularly with modifications (lower whole-diet nutritional score indicative of better diet quality). CONCLUSION: Including a whole-grain component in the Nutri-Score algorithm is justified to align with dietary guidelines and better reflect whole grain as a contributor to improved dietary quality. Further research is required to test alternative algorithms and potentially other nutrient profiling systems.
