Data from the National Diet and Nutrition Survey (NDNS; 2019-2023) shows that several population groups are now classified as mildly iodine deficient, including women of childbearing age. This is a change from previous NDNS data where these groups were iodine sufficient. As iodine is needed for thyroid-hormone production, which are essential for brain development, iodine deficiency prior to, and during, pregnancy may have implications for child cognition - including lower IQ. However, the evidence base for the health effects of mild deficiency is not as strong as in severe deficiency. The WHO recommends salt iodisation to control iodine deficiency in a population, but such a policy was never introduced in the UK and iodised salt is not widely available. While UK milk is rich in iodine and is the principal source, the rise in popularity of plant-based milk alternatives may increase the risk of iodine deficiency. It may be necessary to give personalised advice to those with low iodine intake, but identify those at risk is challenging owing to a lack of a biomarker for iodine in an individual. Population-wide approaches may be required in the UK - for example, fortification of bread with iodised salt or mandatory iodine fortification of plant-based dairy alternatives. This review will critically discuss (i) the data on iodine deficiency in the UK (ii) the evidence base for the health implications of mild deficiency and (iii) the potential public-health solutions.","PeriodicalId":20751,"journal":{"name":"Proceedings of the Nutrition Society","volume":" ","pages":"1-8"},"PeriodicalIF":4.5,"publicationDate":"2026-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145918050","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}

Medium-chain triglyceride (MCT) supplementation is widely recommended and used as the main dietary management in infants, however evidence for its use is limited and there is uncertainty regarding the optimal percentage (proportion of total fat that is MCT) and dose (grams/kilogram/day, g/kg/d). The aim was to review the evidence for the impact of MCT on fat absorption, growth, nutritional status and clinical outcomes in infants with biliary atresia and the optimal nutrition profile of MCT supplementation. A scoping review found that the mostly observational, historic evidence for MCT supplementation pointed to greater fat absorption during MCT supplementation compared to no supplementation, but also some evidence of a risk of essential fatty acid deficiency with very high MCT percentage. Only six studies have investigated MCT percentages and only three reported MCT dose. One analysis of MCT in the largest cohort of biliary atresia patients ever presented (n = 200), found no association between MCT percentage with growth, nutritional status or clinical outcomes. Counterintuitively, there was an unexpected inverse association between MCT dose and growth. A possible interpretation was that increased MCT was a consequence of poor growth rather than a cause, as infants either drank more or dietitians prescribed more MCT as fat malabsorption worsened. In conclusion, MCT is widely recommended, however, the evidence for its use is lacking and there remains uncertainty about the optimum percentage and dose for infants with biliary atresia.","PeriodicalId":20751,"journal":{"name":"Proceedings of the Nutrition Society","volume":" ","pages":"1-8"},"PeriodicalIF":7.1,"publicationDate":"2026-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7618622/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145918256","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This surgery creates an opening in the abdominal wall (stoma), allowing for diversion of egesta into a disposable pouch. This procedure impacts nutrient absorption meaning people living with an ileostomy may be subject to sub-optimal nutrition, often compounded by the low-fibre diet - which is frequently encouraged post-operatively. This review explores the restrictive dietary patterns of this population and their effects on nutrition and quality of life, alongside current approaches to improve dietary management and health outcomes. Dietary restriction beyond the post-operative period is frequently reported, with avoidance of high-fibre foods (e.g., fruits and vegetables) being most prevalent. These long-term dietary changes are presumed to impact nutritional status, with current evidence suggesting diminished bone mineral density and vitamin B12. High-output stoma (HOS) and dehydration are significant issues for people living with an ileostomy, and dietary management of stoma output and other ileostomy-related symptoms is a major contributor to food avoidance. The efficacy of oral rehydration solutions (ORS) in management of HOS is well-established; however, due to high concentrations of glucose and sodium, the palatability of such treatments is poor, impacting patient adherence. Encouragingly, personalised dietary advice has shown some positive effects on both quality of life and nutritional outcomes for people living with an ileostomy. However, a greater understanding of dietary management is needed, and there remains scope to improve current dietary advice and enable people living with an ileostomy to benefit from a more complete and unrestricted diet.","PeriodicalId":20751,"journal":{"name":"Proceedings of the Nutrition Society","volume":" ","pages":"1-14"},"PeriodicalIF":4.5,"publicationDate":"2026-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145918134","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 are problems with monitoring diet and malnutrition screening such as difficulty remembering, lack of time, or needing a dietician to interpret the results. Computerised tailored education may be a positive solution to these issues. Due to the rise in smartphone ownership the use of technology to monitor diet is becoming more popular. This review paper will aim to look at the issues with current methods of dietary monitoring particularly in older adults, it will present the benefits and barriers of using to monitor food intake. It will discuss how a photo food monitoring app was developed to address the current issues with technology and how it was tested with older adults living in community and care settings. The prototype was co-developed and incorporated automated food classification to monitor dietary intake and food preferences and tested with older adults. The prototype was usable to both older adults and care workers and feedback on how to improve its use was collected. Key design improvements to make it quicker and more accurate were suggested for future testing in this population.

This review explores strategies to enhance dietary intake in this population group. Several key interventions are highlighted, including offering high-energy and protein-fortified meals and snacks, optimising the visual appeal and presentation of foods, enhancing flavours, and providing finger foods or modified textures to support consumption. Familiarity with fortified foods may encourage acceptance and increase intake, while improving food aesthetics and incorporating varied flavours can enhance enjoyment and promote consumption. Flavour enhancement may help compensate for decline in smell and taste sensitivity often experienced by older people, helping to sustain interest in food and promote greater intake. Finger foods present a practical solution for older adults with physical impairments, allowing for easier handling and self-feeding. Additionally, for individuals with dysphagia or chewing difficulties, texture-modified diets tailored to their needs support safe food intake. Research suggests that refining food presentation through techniques such as moulding and 3D printing may improve palatability and appeal, potentially boosting consumption among older adults. Addressing sensory preferences and physical challenges associated with eating is critical to ensuring adequate nutrition and promoting overall wellbeing in the elderly population. This review underscores the importance of multifaceted dietary strategies, advocating for personalised interventions that align with older individuals' needs and preferences to enhance food intake and nutritional status.","PeriodicalId":20751,"journal":{"name":"Proceedings of the Nutrition Society","volume":" ","pages":"1-7"},"PeriodicalIF":4.5,"publicationDate":"2026-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145912769","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}

This review focuses on an aspect of undernutrition that is often overlooked, namely loss of appetite, and will discuss the challenges in this under-researched field from the perspective of geriatric medicine. Appetite decline is common in later life and predicts undernutrition in older populations. As such, timely identification and intervention on poor appetite could delay onset or progression of undernutrition to optimise healthy ageing and maintain independence. In addition, management of undernutrition ultimately requires the individual to meet their nutritional requirements. However, unless attention is paid to mitigating appetite decline, strategies to improve intake are likely to be ineffective. Treatment for appetite decline is challenging due to the multiple and complex underlying mechanisms. Current evidence is limited to a few trials targeting older people including flavour enhancement and fortification or supplementation, lifestyle measures such as increasing physical activity and social interaction, and medications, all with mixed results. Progress on treatments for appetite decline has been hampered by a lack of distinction from undernutrition but also perhaps the approach to it as a concept. Categorising appetite decline in ageing as a geriatric syndrome could aid progress in the unification of approaches to mechanistic research, assessment and management strategies, which are likely to be most effective when in multi-component form and underpinned by the principles of Comprehensive Geriatric Assessment (CGA).","PeriodicalId":20751,"journal":{"name":"Proceedings of the Nutrition Society","volume":" ","pages":"1-6"},"PeriodicalIF":4.5,"publicationDate":"2025-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145850637","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 focus is on three key nutrients of concern-trans fatty acids, salt and sugar.In recent times, food reformulation has been categorised as either mandatory or voluntary, a distinction that can help assess policy effectiveness. However, this binary classification oversimplifies a far more complex landscape. Some policies-whether mandated by government or voluntarily suggested to industry-are explicitly intended to trigger reformulation. Others, by contrast, may have never been designed with the intention to encourage reformulation but have nonetheless prompted significant changes in product composition, intake and potential health outcomes.Within what is commonly described as mandatory reformulation, for example, we find a broad mix of policy tools that operate very differently. Some, such as the UK's Soft Drinks Industry Levy, were deliberately created to incentivise reformulation by applying financial pressure. Others, including front of pack nutrition labelling systems (particularly warning labels) and school food standards have encouraged reformulation only as a positive unintended consequence. These indirect drivers are not always evaluated for their impact on reformulation, which may lead to an incomplete understanding of their contribution to reducing intake nutrients of concern and health outcomes.Nevertheless, emerging evidence suggests no single policy encourages reformulation alone, instead a combination of approaches are likely to drive it and contribute to meaningful and sustained food system change.","PeriodicalId":20751,"journal":{"name":"Proceedings of the Nutrition Society","volume":" ","pages":"1-23"},"PeriodicalIF":4.5,"publicationDate":"2025-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145834658","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}

Established links include maternal diet quality with conception rates, micronutrient sufficiency before and during pregnancy with preterm birth prevention, gestational vitamin D intake with offspring bone health, preconception iodine status with child IQ, adiposity with offspring obesity and maternal stress with childhood atopic eczema. Animal studies demonstrate that early-life environmental exposures induce lasting phenotypic changes via epigenetic mechanisms, including DNA methylation, histone modifications and non-coding RNA, with DNA methylation of non-imprinted genes most extensively studied. Human data show that nutrition during pregnancy induces epigenetic changes associated with childhood obesity risk, such as Antisense long Non-coding RNA in the INK4 Locus (ANRIL, a long non-coding RNA) methylation variations linked to obesity and replicated across multiple populations. Emerging insights reveal that paternal nutrition and lifestyle also modify sperm epigenomics and influence offspring development. Although nutritional-randomised trials in pregnancy remain limited, findings from the NiPPeR trial showed widespread preconception micronutrient deficiencies and indicated that maternal preconception and pregnancy nutritional supplementation can reduce preterm birth and early childhood obesity. The randomised trials UPBEAT and MAVIDOS have shown that nutritional intervention can impact offspring epigenetics. Postnatal nutritional exposures further influence offspring epigenetic profiles, exemplified by ALSPAC cohort findings linking rapid infant weight gain to later methylation changes and increased obesity risk. Together, these studies support a persistent impact of maternal and early-life nutrition on child health and development, underpinned by modifiable epigenetic processes.","PeriodicalId":20751,"journal":{"name":"Proceedings of the Nutrition Society","volume":" ","pages":"1-6"},"PeriodicalIF":4.5,"publicationDate":"2025-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7618621/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145834523","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
