The prevalence of undernutrition in community-dwelling older adults is about 8.5%, but higher in vulnerable subgroups such as the oldest old (19.3%), those reporting poor appetite (22.4%), and those receiving home care (15.8%). Frequently reported risk factors for undernutrition in the community include poor appetite, functional limitations and previous hospitalisation. The Determinants of Malnutrition in Aged Persons (DoMAP) model provides a clear framework to structure the different direct and indirect potential determinants of undernutrition in old age. Low BMI as well as involuntary weight loss, both important phenotypic criteria of undernutrition, are associated with early mortality in older adults. Furthermore, undernutrition in community-dwelling older adults is associated with a subsequent increased risk of frailty, falls, functional decline and rehospitalisation. Qualitative studies indicate a poor undernutrition awareness among healthcare professionals working in community care as well as among older adults themselves. The Malnutrition Awareness Scale can be used to objectively measure an older persons' undernutrition awareness. In conclusion, the prevalence of undernutrition among older adults living in the community is substantial and has several negative consequences for health and functioning. Strategies towards greater undernutrition awareness by primary care professionals as well as older adults themselves is therefore necessary.","PeriodicalId":20751,"journal":{"name":"Proceedings of the Nutrition Society","volume":" ","pages":"1-7"},"PeriodicalIF":4.5,"publicationDate":"2025-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145065404","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Those with social disadvantage experience greater diabetes prevalence, morbidity and mortality. Gestational diabetes (GDM) is an established factor for T2DM, with 3-4 times greater risks among women who are Black, Hispanic and South and South East Asians. Lifestyle interventions that include diet and physical activity reduce T2DM in at-risk populations, including women with prior GDM, regardless of ethnicity. However, migrant women from non-Western backgrounds are less likely to engage with the programme despite its efficacy. This review paper aims to describe the social disparities in GDM globally, with a focus on equity issues and interventions in Australia. It outlines a five-part approach to solutions that move us towards equity in reach and uptake for women from non-Western migrant backgrounds in Australia. Culturally inclusive solutions start with evaluating reach in underserved groups through equity audits or stratified analyses and identifying groups where reach is low. Community partnerships can then be formed with key actors across health and social sectors identified through stakeholder mapping. Effective reach strategies, including implementation and evaluation plans, will be co-developed through these partnerships, addressing risk factors, enablers and barriers to a healthy lifestyle. Solutions that integrate medical and social services, such as social prescribing, could facilitate healthy lifestyle choices through restructuring the social environment of the individual. These steps lead to interventions that promote social cohesion and resilience, enabling individuals to attain health and well-being in the face of external challenges.","PeriodicalId":20751,"journal":{"name":"Proceedings of the Nutrition Society","volume":" ","pages":"1-7"},"PeriodicalIF":4.5,"publicationDate":"2025-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145065372","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There is a growing consensus that a shift from animal-based to plant-based diets is essential for both human health and environmental sustainability. This review explores the integration of sustainability competences into nutrition education, emphasising how systems thinking, strategic thinking, values thinking, futures thinking and interpersonal competences can contribute to the production of improved dietary guidelines. By applying these competences to the criticisms of the Planetary Health Diet, the Nordic Nutrition Recommendations and the Mediterranean diet as examples, this review highlights the tactics used by specific stakeholders to undermine sustainable healthy dietary guidelines. The review paper concludes by advocating for future dietary guidelines that are free of financial conflicts of interest, decolonised and developed through participatory processes in order to ensure that they are equitable, sustainable and aligned with the needs of diverse populations.","PeriodicalId":20751,"journal":{"name":"Proceedings of the Nutrition Society","volume":" ","pages":"1-10"},"PeriodicalIF":4.5,"publicationDate":"2025-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145065302","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Evidence synthesis. Global. None. We describe how timely food and beverage pricing data can provide transparency in the food industry and identify key areas for intervention. However, government policies that improve food affordability are often short-lived and lack sustained commitment. Achieving meaningful impact will require long-term, cross-sectoral actions that are led by governments to support food security, healthy diets and resilient sustainable food systems. This will necessitate a better understanding of how the political economy enables (or hinders) policy implementation, including through coherent problem framing, mitigating conflicts of interest in policymaking, working together as coalitions and developing and utilising evidence on the food security and related impacts of food pricing and affordability policies. Diverse actors must be better equipped with robust data platforms and actionable policy solutions that improve the affordability of healthy and sustainable diets, including by lowering food prices and addressing the broader socio-political determinants of food insecurity.","PeriodicalId":20751,"journal":{"name":"Proceedings of the Nutrition Society","volume":" ","pages":"1-12"},"PeriodicalIF":4.5,"publicationDate":"2025-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145001328","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Accumulating evidence indicates that these compounds exert beneficial effects against cardiometabolic diseases, and this review will provide a summary of current knowledge in this area. Epidemiological and clinical data collectively suggest that intake of flavonoids reduces the risk of cardiovascular disease (CVD), with the evidence being particularly strong for the flavan-3-ol subclass. However, to provide adequate dietary recommendations, a better understanding of their estimated content in foods and intake among the general public is needed. Regarding mechanisms of action, we now know that it is unlikely that (poly)phenols act as direct antioxidants in vivo, as it was hypothesised for decades with the popularity of in vitro antioxidant capacity assays. One of the reasons is that upon ingestion, (poly)phenols are extensively metabolised into a wide array of circulating metabolites with different bioactivities than their precursors. Well-conducted in vitro and in vivo studies and human nutrigenomic analysis have revealed new molecular targets that may be underlying the health benefits of (poly)phenols, such as the nitric oxide pathway. Recently, a bi-directional relationship was established between (poly)phenols and the gut microbiota, suggesting that individual gut microbial metabolising capacity may be a key factor explaining the variability in the cardiometabolic response to (poly)phenols. Future research is needed to elucidate which are the key factors affecting such capacity, and whether it can be modulated, along with the mechanisms of action.","PeriodicalId":20751,"journal":{"name":"Proceedings of the Nutrition Society","volume":" ","pages":"279-289"},"PeriodicalIF":4.5,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139692793","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ageing is associated with a gradual decline in muscle mass, specifically atrophy of type II fibres, that is exacerbated by periods of (in)voluntary muscle disuse. At the metabolic level, in otherwise healthy older adults, muscle atrophy is underpinned by anabolic resistance which describes the impaired MPS response to non-pharmacological anabolic stimuli, namely, physical activity/exercise and amino acid provision. Accumulating evidence implicates a mechanistic role for n-3 PUFA in upregulating MPS under stimulated conditions (post-prandial state or following exercise) via incorporation of EPA and DHA into the skeletal muscle phospholipid membrane. In some instances, these changes in MPS with chronic ո-3 PUFA ingestion have translated into clinically relevant improvements in muscle mass, strength and function; an observation evidently more prevalent in healthy older women than men. This apparent sexual dimorphism in the adaptive response of skeletal muscle metabolism to EPA and DHA ingestion may be related to a greater propensity for females to incorporate ո-3 PUFA into human tissue and/or the larger dose of ingested ո-3 PUFA when expressed relative to body mass or lean body mass. Future experimental studies are warranted to characterise the optimal dosing and duration of ո-3 PUFA ingestion to prescribe tailored recommendations regarding n-3 PUFA nutrition for healthy musculoskeletal ageing into later life.","PeriodicalId":20751,"journal":{"name":"Proceedings of the Nutrition Society","volume":" ","pages":"234-244"},"PeriodicalIF":4.5,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138177168","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The network has brought together a team from a range of disciplines, while the inclusion of non-academic users and other stakeholders, such as pupils and parents, has allowed the co-development of research priorities and questions. This network has used a combination of workshops, working groups and pump-priming projects to explore the school food system, as well as creating a systems map of the UK school food system and conducting network analysis of the newly established network. Through understanding the current food system and building network expertise, we hope to advance research and policy around food in schools. Further funding has been achieved based on these findings, working in partnership with policymakers and schools, while a Nutrition Society Special Interest Group has been established to ensure maximum engagement and future sustainability of the network.
