Therefore, we aimed to investigate the association between dietary fibre intake and remnant serum cholesterol levels in older Korean adults. We used data from the 2016 to 2021 Korea National Health and Nutrition Examination Survey, which included 8212 older adults. Serum remnant cholesterol levels were calculated by subtracting the low-density lipoprotein cholesterol and high-density lipoprotein cholesterol levels from the total cholesterol level. Hyperremnant cholesterolaemia was defined as a serum remnant cholesterol level of ≥ 30 mg/dL. Dietary fibre intake was classified on the basis of adequate intake (AI). A multivariate logistic regression analysis was performed to examine the association between dietary fibre intake and remnant serum cholesterol levels. The odds ratio of hyper-remnant cholesterol aemia was 1.26 times higher in older adults with fibre intake below AI than in those with fibre intake above AI (95% confidence interval 1.06-1.48, p < 0.01). This study revealed that dietary fibre intake was inversely associated with serum remnant cholesterol levels in older Korean adults. Therefore, dietary fibre can be considered a novel therapeutic strategy for lowering remnant cholesterol and may benefit older adults at risk of CVD in terms of the prevention and inhibition of progression.</p>","PeriodicalId":48536,"journal":{"name":"Nutrition Bulletin","volume":" ","pages":""},"PeriodicalIF":3.6,"publicationDate":"2025-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145132238","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"What Is Known About the Fish Intake of People Living in Disadvantaged Communities in the UK? A Scoping Review.","authors":"Sarah Gale, Roseline Aboluwade, Louise Hunt, Clare Pettinger","doi":"10.1111/nbu.70030","DOIUrl":"https://doi.org/10.1111/nbu.70030","url":null,"abstract":"<p><p>Fish provides essential nutrients, including protein, omega-3 fatty acids (oily fish) and other micronutrients, and may be seen to have a prominent role in protecting against non-communicable diseases, especially cardiovascular disease. Recent UK National Diet and Nutrition Survey analysis suggests people are not meeting their weekly fish intake recommendation of at least two portions per week, of which one should be oily. Lower socioeconomic groups are more likely to eat poor-quality diets, with low fish intake, resulting in poor health outcomes. The aim of this scoping review was to examine the factors influencing fish consumption in people living within 'disadvantaged communities' in the UK. The review was guided by Arksey and O'Malley's five-stage framework and Preferred Reporting Items for Systematic Reviews (PRISMA) checklist. Peer-reviewed literature was searched, focusing on studies carried out in the UK (published in CINAHLPlus, PubMed, Scopus, Web of Science and MEDLINE) and grey literature (Google Scholar, consultations and websites) between January 2000 and December 2023. Selected studies were reviewed and analysed descriptively or using content analysis. A total of n = 26 papers were reviewed, with collated findings suggesting a nuanced picture in relation to fish intake within 'disadvantaged communities'. Specific barriers were identified, including physical and economic accessibility, with poor access to fish and the high cost of fish (especially oily) positively associated with income level. Demographic characteristics of age, gender, and ethnicity were shown to influence fish intake. Education level also plays a role, namely the higher the education level, the higher the likelihood of regular (i.e., weekly or daily depending on study) fish consumption. Similarly, cultural factors can determine fish-related food choices in adults, which can also influence children's fish intake. Despite some inherent limitations, this review provides important insights into the fish intake of disadvantaged communities. Recommendations are made for researchers, practitioners, and policy makers engaged in (blue) food system strategies to inform the design of interventions and campaigns to promote fish intake, enhance education of its health benefits, and skills in its preparation/cooking in disadvantaged communities to support action to tackle health inequalities.</p>","PeriodicalId":48536,"journal":{"name":"Nutrition Bulletin","volume":" ","pages":""},"PeriodicalIF":3.6,"publicationDate":"2025-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145114761","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To date the specific properties of UPF foods and diets that may be responsible for driving higher energy intakes remain unclear. A comparison of the diets in the single RCT to date showed a significantly higher eating rate (g/min, ER) for meals in the UPF diet compared to those in the minimally processed diet. Numerous acute feeding trials have shown that foods with textures that promote a slower ER tend to be consumed in smaller portions compared to those consumed at a faster ER. Here, we describe the rationale and approach for the Restructure RCT with the primary aim to determine the effect of meal texture-derived ER (g/min) of UPF diets ('UPF Slow ER' vs. 'UPF Fast ER') on daily ad libitum energy intake (kcal/day) across a 14-day period. The secondary objectives of the Restructure RCT are to compare changes in body composition and metabolic markers following the same two diets. We hypothesise that texture-derived differences in ER will moderate food and energy intakes from UPF diets such that participants will consume less when they encounter textures that promote a slower eating rate. The outcomes of the Restructure RCT aim to provide new insights on the proposed mechanisms by which UPF are thought to promote greater energy intakes, and aid in the development of food-based strategies to moderate dietary energy intakes from processed foods.

This study updates the prevalence, demographics and eating motives of vegetarians and vegans using data from the 3rd Bavarian Food Consumption Survey (BVS III; 2021-2023), a repeated, population-based, representative study. Stratified random sampling recruited 1503 adults aged 18-75 years via resident registration offices. Dietary intake was assessed using repeated 24-h recalls. Participants self-identified their diets.

Associations between exercise performance and gut microbiome composition and metabolites have also been identified in human studies.

We conducted a randomised controlled cross-over trial with 21 healthy and active males (35.0 ± 6.9 years; 24.4 ± 2.7 kg/m²) to investigate the effect of 15 g of inulin (prebiotic) on exercise performance (15 km cycle time trial), compared to placebo. Time to completion of a 15 km time trial was the primary outcome, while plasma acetate concentration and markers of inulin fermentation (breath H₂ concentration) and muscle oxygenation were measured to explore potential mechanisms of action. Time to complete the 15 km time trial was not affected by inulin mean difference between inulin and placebo trials: (-10.37 s, 95% CI [-150.8, 130.1 s], p = 0.884). The marker of inulin fermentation (H₂ concentration increase from baseline) was significantly higher in inulin compared to placebo condition (+42.61 ppm, 95% CI [30.04, 55.19], p = 0.001 and +31.13 ppm, 95% CI [3.73, 58.51], p = 0.029, respectively), but plasma acetate concentration did not differ between conditions. Likewise, markers of muscle oxygenation were not different between inulin and placebo. Our current results do not support the acute use of prebiotics to improve exercise performance in adults. Possible explanations for the absence of ergogenic effects may be that the timing between prebiotic ingestion and exercise was too short to allow for complete fermentation into acetate, participants were in a fasted rather than a fed state, or that the single dose of supplement was insufficient.

The question, with a focus on fungal proteins, is where to best place them within Food-based Dietary Guidelines? A Nutrition Society Member-Led meeting was convened as a roundtable on 12th February 2024 to gather views on whether there is a specific role for fungal protein within Food-based Dietary Guidelines and how this role is best communicated. The intention of the roundtable was to establish areas of consensus or any disparities, and pinpoint future research directions. The roundtable format included three contextual presentations followed by discussions around seven core statements. A group of 11 experts from academia, policymaking and industry participated. There was agreement that health and sustainability research had advanced (for mycoprotein in particular). Subsequently, there is no reason to exclude fungal-derived proteins from Food-based Dietary Guidelines. The panel agreed on the need for an updated database on mycoprotein intakes in different countries along with long-term population studies comparing fungal, plant and meat sources against health and sustainability outcomes.
