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 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.

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.</p>","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}

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.

This review focuses on one critical intersection: older populations living with overweight and obesity in the context of sustainable nutrition. Obesity and sarcopenia, particularly the co-occurrence called sarcopenic obesity, are often overlooked until the onset or exacerbation of other diseases necessitates secondary care. Preventing sarcopenic obesity requires reducing excess fat mass while preserving muscle mass and function. This involves lowering total energy intake while ensuring adequate protein intake in terms of quantity, quality and distribution, combined with physical activity, particularly resistance exercise. Short-term studies show that both the source and dose of dietary protein significantly influence muscle protein synthesis rates. Longer-term studies examining the impact of plant-based diets on muscle health in older adults with or without overweight or obesity remain limited. Animal protein have shown a modest advantage over most plant-based protein in supporting muscle mass. Qualitative studies suggest that emphasising both the health benefits and palatability of plant-based protein sources is key to promoting dietary changes in older adults. In older adults with obesity, it is challenging to combine energy restriction with higher protein intake, especially when protein sources are plant-based.

Appetite and EI are influenced by complex, multifactorial pathways involving physiological, psychological, environmental, social and cultural factors. Early research investigating the association of body composition with appetite and EI focused on FM; however, the role of FFM in appetite control is gaining increasing attention. Studies have shown that FFM is positively associated with EI in younger populations, including infants, adolescents and adults. In contrast, FM appears to have no association or a weak inverse association with appetite/EI. However, research in older adults is limited, and the underlying mechanisms are not fully understood. It has been suggested that one way in which FFM may influence appetite and EI is by impacting resting metabolic rate (RMR). FFM, which includes metabolically active tissues including skeletal muscle and organs, represents the largest determinant of RMR and therefore may influence appetite and EI by ensuring the energetic requirements of crucial tissue-organs and metabolic processes are reached. Given that declines in FFM and RMR are common with ageing, they may be possible targets for interventions aimed at improving appetite and EI.

This review considers the potential of probiotics, prebiotics, and synbiotics as interventions to mitigate sarcopenia based on animal and human studies, while providing a critique of present barriers that need to be addressed. Preclinical models, including germ-free mice and faecal microbiota transplantation, demonstrate that gut microbiota from healthy or young donors may enhance overall muscle health via reductions in inflammatory and muscle atrophy markers. Limited human studies show that probiotics such as <i>Lactobacillus</i> and <i>Bifidobacterium</i> could improve branched-chain amino acid (BCAA) bioavailability and potentially sarcopenia indices, although findings have been inconsistent. Particularly, challenges including inconsistent microbial assessments, lack of dietary control and interindividual variability due to diet, age, genetics, comorbidities and medications may hinder progress in this field. Delivery methods (e.g. capsules, fermented foods or fortified products) could further complicate efficacy through probiotic stability and dietary restrictions in older adults. Standardised protocols [e.g. Strengthening The Organisation and Reporting of Microbiome Studies (STORMS) checklist] and multi-omics approaches may be critical to address these limitations and identify microbial signatures linked to sarcopenia outcomes.

Diet- and nutrient-related risk factors for oral diseases include high intakes of free sugars, low intakes of fruits and vegetables and nutrient-poor diets which are similar to diet- and nutrient-related risk factors for systemic diseases. Oral diseases are chronic diseases. Once the disease process is initiated, it persists throughout the lifespan. Pain and tissue loss from oral disease leads to oral dysfunction which contributes to impaired biting, chewing, oral motility and swallowing. Oral dysfunction makes it difficult to eat nutrient-dense whole grains, fruits and vegetables associated with a healthy diet. Early childhood caries (ECC) associated with frequent intake of free sugars is one of the first manifestations of oral disease. The presence of ECC is our 'canary in the coal mine' for diet-related chronic diseases. The dietary sugars causing ECC are not complementary to an Eatwell Guide compliant diet, but rather consistent with a diet high in energy-dense, nutrient-poor foods - typically ultra-processed in nature. This diet generally deteriorates throughout childhood, adolescence and adulthood increasing the risk of diet-related chronic diseases.
