For years, it has therefore been considered an antinutrient. Assessing dietary phytate intake at the population level is important for understanding potential risks to micronutrient absorption. However, the phytate intake in the national diet of Turkey has not yet been evaluated. In this study, daily energy and nutrient intakes were obtained from dietary recalls conducted as part of the Turkey Nutrition and Health Survey (TNHS) 2010 and 2017. The Global Food Composition Database for Phytate (PhyFoodComp) was used to determine the phytate content in the national diet, as well as the molar ratios of phytate to iron, zinc, and calcium. The data from 7017 and 9832 participants of TNHS 2010 and TNHS 2017, respectively, were analysed. The median daily dietary phytate intakes were 535.3 mg in 2010 and 658.0 mg in 2017 (p < 0.001). As revealed in both surveys, bread and cereals comprised the food group that contributed most to the daily phytate intake. Most of the sample population exhibited moderate zinc bioavailability and low iron bioavailability as indicated by the phytate-mineral molar ratios. Overall, this study reveals increased phytate intake in Turkey over the years. Although minimizing phytate consumption in people without a dietary mineral inadequacy is unnecessary, consuming plant foods as sources of iron and other nutrients that increase iron absorption among the population in Turkey, where anemia is prevalent, is recommended.</p>","PeriodicalId":48536,"journal":{"name":"Nutrition Bulletin","volume":" ","pages":"67-78"},"PeriodicalIF":3.6,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145589384","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}

This cross-sectional study employed a mixed-methods approach, combining structured quantitative measures and open-ended qualitative questions in a digital survey. A total of 785 university students aged 18-29 from Türkiye participated in the study. The survey included the Behavioural Scale for Sustainable Nutrition, the Global Climate Change Awareness Scale, and the Attitudes Toward Alternative Protein Sources Questionnaire. Descriptive statistics, independent t-tests, one-way ANOVA, post hoc Tukey HSD tests, and correlation analyses (Pearson/Spearman) were conducted to examine the associations between climate change awareness, sustainable nutrition behaviours, and the acceptability of alternative protein sources, including edible mushrooms, algae, flowers, grasshoppers, crickets, and cultured meat. A statistically significant but moderate positive relationship was observed between climate change awareness and sustainable nutrition behaviours, particularly in food purchasing habits. A weaker but positive association was found for food preference, food waste reduction, and seasonal and local dietary practices. Participants reported low familiarity with alternative protein sources, with the highest acceptability for edible mushrooms (74.5%), followed by edible flowers (37.8%) and cultured meat (14.4%). While greater climate change awareness was linked to a higher willingness to consume certain alternative protein sources, this did not consistently translate into broader acceptance.

To address this, a virtual roundtable was held in October 2024 to provide a setting for a technical discussion among those working in food processing, technology and engineering and related fields. The aims were to explore whether (a) the concept of ultra-processed foods (UPF) as a whole (or any elements thereof) may be useful to consider in the development of healthier and more sustainable foods, including its strengths, opportunities, weaknesses and barriers; and (b) where there might be opportunities for food technologists to improve current approaches to food processing for human health in the future. Presentations focussed on reformulation and included a critique of the evidence and proposed mechanisms linking UPF consumption to food intake and health. Areas of discussion included use and replacement of ingredients deemed to be 'UPF'; material properties of foods; advances in food production; consumer communication; practicalities of consuming a healthy, sustainable diet; food systems considerations; environmental sustainability in food processing and the role of meat alternatives. Looking ahead, participants identified opportunities for improvements centred around four themes: target areas and considerations for innovation and reformulation that can be suggested based on current or future capability; potential definitions/targets that industry can work towards to improve the healthiness of products and related evidence needs; greater transdisciplinary working (cross-sector, food systems approaches); consumer-related issues and potential policy/regulatory changes. Caution was expressed around both 'overprocessing' and misplaced reformulation efforts to the detriment of health. However, a potential role for consumer education around food processing techniques and ingredients was identified and the importance of continued advancements in food processing and technology in the production of healthier, sustainable food was highlighted.</p>","PeriodicalId":48536,"journal":{"name":"Nutrition Bulletin","volume":" ","pages":"127-147"},"PeriodicalIF":3.6,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12930240/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145967534","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the UK, following the announcement and implementation of the Soft Drinks Industry Levy (SDIL), nearly 9 out of 10 soft drinks contain < 5 g sugar per 100 mL, most of which now contain LNCS. In 2023, the World Health Organisation (WHO) issued a guideline with a conditional recommendation advising that LNCS should not be used as 'a means of achieving weight control or reducing the risk of non-communicable disease' (NCDs). This recommendation potentially conflicted with existing recommendations from several authoritative sources at the time, including the Diabetes UK position statement published in 2018 (developed in collaboration with the British Dietetic Association, BDA and the British Nutrition Foundation, BNF), as well as information on the NHS website, which suggests that LCNS can be helpful in reducing sugar intake. More recently, a working group comprising the BDA, BNF and Diabetes UK produced an updated insight document. This review included a re-evaluation of the WHO's systematic review and meta-analysis, alongside the Scientific Advisory Committee on Nutrition (SACN) statement on the guideline. The narrative review outlines the relationship between LNCS and a range of public health outcomes, including weight management, dental health, cardiovascular disease, type 2 diabetes (T2D), cancer and related risk markers such as appetite and gut microbiome composition. The insights document also considered the safety of LNCS and their impact on overall dietary quality. The insight document informed a subsequent joint position statement from the three organisations, highlighting research gaps and providing practical guidance for healthcare professionals to support individuals living with obesity and diabetes in reducing sugar intake. It also includes recommendations for policymakers and identifies actions for the food industry. The Position Statement emphasises that, while LNCS may not directly promote weight loss or reduce disease risk, they can serve as a useful tool for reducing sugar intake at both individual and population levels, at least acting as a 'stepping stone' from sugar-sweetened foods and unsweetened food and beverages.</p>","PeriodicalId":48536,"journal":{"name":"Nutrition Bulletin","volume":" ","pages":"120-126"},"PeriodicalIF":3.6,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145967467","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}

This systematic review aimed to examine and meta-analyse the existing literature on food insecurity in families of children and young people with ASC. A comprehensive search across nine databases identified 39 papers, of which 11 met the inclusion criteria. Studies were included if they involved autistic children or young people under the age of 25 (and/or their family members) and focused on food insecurity. Eligible studies were critically appraised, and data were synthesised using both narrative and meta-analytic approaches. Meta-analyses of nine studies estimated a pooled prevalence of food insecurity at 29% (SE: 5%; 95% CI: 17%-40%; z = 5.35, p < 0.001), which increased to 31% following adjustment for publication bias. The review also found that food insecurity worsened during the COVID-19 pandemic, contributing to increased caregiver stress and disruptions in eating behaviours. This review demonstrates the high prevalence of food insecurity among families of children with ASC and the complex interplay of social, economic and behavioural challenges they face. Addressing food insecurity in autistic households requires policy responses that extend beyond financial aid to consider the sensory, behavioural and nutritional needs specific to ASC. Future research should adopt standardised measures and prioritise the development and evaluation of inclusive, tailored food support systems that reflect the lived experiences of neurodiverse families.</p>","PeriodicalId":48536,"journal":{"name":"Nutrition Bulletin","volume":" ","pages":""},"PeriodicalIF":3.6,"publicationDate":"2026-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146214567","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.
