Government policies designed to address diet inequality in the UK have historically had minimal impact on population diet and health and may have even widened existing inequalities. Therefore, the effect of nutrition policies on those experiencing FI in the context of the current cost-of-living crisis needs to be better understood. The aim of the Diet and Health Inequalities (DIO Food) project is to work with early years, people living on a low income and retailers to generate opportune evidence-based research and commentary that will inform diet-related health inequalities policy and practice. DIO Food is related to the existing Food Insecurity in people living with Obesity (FIO Food) project, which consists of four interlinked work packages (WPs1-4). DIO Food consists of three interlinked work packages (WPs5-7), which enhance the scope of FIO Food, and are described in this article. WP5 addresses a paucity of research on maternal and infant food insecurity in the UK, by applying a qualitative research approach to capture parents' and carers' perceptions of the relationship between the food system and other influences impacting infant feeding practice, associated with the cost-of-living crisis. WP6 will conduct the first-ever cross-retailer independent evaluation of England's high fat, sugar and salt (HFSS) product placement legislation. Researchers will analyse store-level supermarket sales data provided by large UK retailers to produce sector-level insights into whether HFSS legislation reduced HFSS purchasing, improved the healthiness of retailer product portfolios, and was equitable across areas with different characteristics. WP7 will support WP5 and 6, by strengthening engagement with key stakeholders, including at-risk consumers and representatives of major supermarkets, and effectively translating research outcomes and stakeholder perspectives for policy and industry decision-makers.</p>","PeriodicalId":48536,"journal":{"name":"Nutrition Bulletin","volume":" ","pages":"561-571"},"PeriodicalIF":4.6,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142356150","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 was conducted between March 2022 and April 2022 at Ondokuz Mayıs University in Samsun, Türkiye, and included 859 university students (56.1% women; mean age 22.57 ± 2.75 years). Sociodemographic characteristics were collected. The CS and FS measure and the Mediterranean Diet Adherence Screener (MEDAS) were administered. The mean MEDAS, CS and FS scores were 4.77 ± 1.97, 59.10 ± 18.17 and 77.81 ± 22.27, respectively. Those with higher MEDAS scores (quartile three and quartile four-Q3 and Q4) had significantly higher CS scores than those with lower scores (Q1 and Q2), while those in the lowest quartile (Q1) had lower FS scores than all other quartiles (p < 0.001). Total scores of CS and FS positively, although weakly, correlated with MEDAS (r = 0.227 and r = 0.296; p < 0.001). Two separate models for CS and FS were analysed; along with access to kitchen facilities, CS and FS contributed the most variability, accounting for 8.9% and 11.8% of the variance in MEDAS, respectively (p < 0.001).

MASLD is considered the hepatic manifestation of the metabolic syndrome, pathophysiologically underpinned by insulin resistance and frequently co-exists with hypertension, central obesity and dyslipidaemia. Currently, safe and effective pharmacotherapies for MASLD are limited, making weight loss with lifestyle changes the mainstay therapy. A Mediterranean diet (MedDiet) has emerged as an effective dietary pattern for preventing and managing MASLD, but most studies have been conducted in Mediterranean countries, necessitating further investigation into its benefits in Western populations. Additionally, the effect of holistic multimodal lifestyle interventions, including physical activity combined with the MedDiet, is not well established. Finally, MASLD's widespread prevalence and rapid growth require improved accessibility to interventions. Digital health delivery platforms, designed for remote access, could be a promising approach to providing timely support to individuals with MASLD. This narrative review summarises the current evidence related to the effects of the MedDiet in Western, multicultural populations with MASLD. This includes a detailed description of the composition, prescription and adherence to dietary interventions in terms of how they have been designed and applied. The evidence related to the role of physical activity or exercise interventions prescribed in combination with the MedDiet for MASLD will also be reviewed.

Prolonged low intakes of vitamin B12, such as seen in those adhering to a vegan diet, lead to physiological deficiency of vitamin B12 and an elevated risk of B12-related morbidity. However, while serum B12 serves as a conventional biomarker for assessing B12 status, its utility is limited given its sensitivity and specificity in ascribing physiological deficiency of B12 and the functional vitamin B12 status of those adhering to vegan diets is unclear. We conducted a systematic review and meta-analysis using data based on the full panel of biomarkers of vitamin B12 status to test whether adherence to a vegan diet is associated with an elevated risk of functional vitamin B12 deficiency compared to vegetarian or omnivorous diets. In addition, subgroup analysis was carried out to look at the effect of vitamin B12 supplement use on B12 status among vegans. Our search identified 4002 records, of which 19 studies met the inclusion criteria for the systematic review and 17 studies were taken forward for the meta-analysis. Meta-analysis results revealed significantly lower serum B12, pmol/ (-0.72 [-1.26, -0.18]; p = 0.01) and elevated total homocysteine, μmol/L (tHcy) (0.57 [0.26, 0.89]; p < 0.001) concentrations, alongside elevated methylmalonic acid, nmol/L (MMA) (0.28 [-0.01, 0.57]; p = 0.06) and lower holotranscobalamin, pmol/ (HoloTC) (-0.42 [-0.91, 0.07]; p = 0.09) levels among vegan adults compared to omnivores, indicating increased functional B12 deficiency in addition to low vitamin B12 status in vegan adults. There were no differences between vegans and vegetarians in HoloTC (0.04 [-0.28, 0.35]; p = 0.814) or MMA (-0.05 [-0.29, 0.20]; p = 0.708), but differences were found in serum B12 (-0.25 [-0.40, -0.10]; p = 0.001) and for tHcy (0.24 [0.09, 0.39]; p = 0.002) concentrations. Subgroup analyses indicated that the use of vitamin B12 supplements among vegans contributes to significant improvements in all biomarker concentrations compared to their unsupplemented counterparts.

Following PRISMA guidelines, a systematic search of PubMed, MEDLINE, Embase, APA PsycArticles and APA PsycINFO was conducted up to 19th August 2022. Study quality was assessed by the Newcastle-Ottawa scale (NOS) and the Cochrane risk of bias tool. Eleven studies (10 cross-sectional and 1 randomised controlled trial [RCT]) were included. Seven cross-sectional studies had very good quality or good quality, and the quality of the RCT was at low risk of bias. These studies examined sugar-sweetened beverages (n = 7), sugar-sweetened foods (n = 4) and/or added sugar (n = 5). The findings suggest a possible positive relationship of added sugar consumption with anxiety disorders, with age as a potential moderator in such association. No conclusions can be drawn on the associations between sugar-sweetened beverages, sugar-sweetened foods consumption and anxiety disorders. Due to the included studies being mostly cross-sectional, the conclusions drawn from the existing evidence should be interpreted with caution.

Low-grade inflammation was calculated by INFLA-score, dietary intake by three 24-h dietary recalls and dietary content analyses by BeBiS™ software. The mean age of the 50 children included in our study was 10.18 ± 3.98 years (5-17 years). UPF accounted for 24.5% of the total daily energy intake of children. In children with higher inflammation scores (INFLA-score ≥ 2), the amount in grams of UPF and the percentage of total energy from UPF were found to be significantly higher (p = 0.030 and p = 0.015, respectively). A weak positive correlation was found between the INFLA-score and the percentage of daily dietary energy intake coming from UPFs (r = 0.350, p < 0.01), the average daily energy intake from UPFs (r = 0.313, p < 0.05), and the average daily amount of UPF consumed (r = 0.260, p < 0.05). The linear regression model revealed that every one-unit increase (1%) in the percentage of total daily energy intake coming from UPF caused an increase in β = 0.154-unit in the INFLA-score. It was found that obesity was not a mediator in the association between the percentages of total energy intake from UPF on the INFLA-score, instead, the energy intake from UPF had a significant direct association with the INFLA-score.
