Many live in precarious situations with little control over their lives. In addition to food parcels, many foodbanks also supply emergency fuel payments. There has been a surge in demand due to the cost of living crisis in the United Kingdom. This qualitative study, using semi-structured interviews, explored the lived experience of people who received a fuel voucher via a foodbank to gain insights into food preparation, eating practices and heating and appliance use in their homes. All participants (n = 6) described a change in life circumstances leaving them at crisis point with overwhelming uncertainty. Using Thematic Analysis, we identified four themes: (1) Bewilderment in using foodbank services; (2) The need to make trade-offs between food and fuel; (3) Feeling shame at using the services and (4) Missing out on pleasurable eating practices. Three case studies give fuller insights and context. All interviewees had acute and complex needs and described being 'at rock bottom', with fuel vouchers viewed as a 'lifeline' to address essential cooking, heating and electrical appliance needs. We, therefore, suggest the need for extra support and follow-up for first-time users who are in a state of denial and shock when seeking help. Further research is needed on how to best help organisations develop strategies to address and ameliorate a sense of powerlessness and shame felt by their clients which likely limits them from seeking help, despite being in acute, complex and dire need.</p>","PeriodicalId":48536,"journal":{"name":"Nutrition Bulletin","volume":" ","pages":"500-512"},"PeriodicalIF":3.3,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10302557","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}

The vitamin D status of the population in the Yunnan Province of Southwest China has not been evaluated to date. Therefore, in this study, we evaluated the vitamin D status according to the serum concentrations of 25-hydroxyvitamin D (25(OH)D) in individuals of Yunnan Province, a low-latitude, high-altitude and multiracial region in China. The data on 25(OH)D concentrations from October 2012 to December 2017 were retrospectively collected and assessed using the laboratory information system from 52 950 hospital-based participants (age, 1 day-96 years; females, 73.74%). The serum concentration of 25(OH)D was evaluated using a chemiluminescent immunoassay. The analysis was stratified by sex, age, sampling season, testing year, minority, residential district, latitude, altitude and meteorological factors. Vitamin D status was classified as follows: severe deficiency: <10 ng/mL; deficiency: <20 ng/mL; insufficiency: <30 ng/mL; and sufficiency: ≥30 ng/mL. The results showed that vitamin D deficiency is highly prevalent in Yunnan Province in a hospital-based cohort, with a deficiency and severe deficiency rate of 65.1% and a sufficiency rate of 5.30%. Significantly lower vitamin D levels and sufficiency rates were observed in females than in males (20.13 ± 7.22 ng/mL vs. 17.56 ± 6.66 ng/mL and 8.20% vs. 4.20%; p < 0.01, respectively); in spring and winter (16.93 ± 6.24 ng/mL; 2.97% and 16.38 ± 6.43 ng/mL; 3.06%, respectively) than in summer and autumn (20.23 ± 7.14 ng/mL; 8.02% and 19.10 ± 6.97 ng/mL; 6.61% [p < 0.01], respectively); and in older individuals (0-6 years: 28.29 ± 13.13 ng/mL vs. >60 years: 14.88 ± 8.39 ng/mL; p < 0.01).

Higher education institutions are increasingly recognising the importance of teaching about sustainability, yet there exists a gap in the literature detailing the awareness of sustainability issues by nutrition students. This study aimed to ascertain the level of knowledge of sustainable diets (SDs), the perceived barriers to their adoption in their own diets, students' experience of university-based teaching about SDs and their views on the future role of the nutrition profession in relation to SD amongst nutrition students on Association for Nutrition (AfN)-accredited degrees. The study assessed environmental and sustainable food literacy (SFL) through an online questionnaire and explored the issues in more detail in virtual or face-to-face interviews in 2019. Quantitative data were analysed using descriptive statistics (Kruskal-Wallis, Jonckheere-Terpstra, independent t-test, Spearman, Pearson Correlations). Qualitative data were analysed using the Braun and Clark (2006) six-step approach to thematic analysis. The questionnaire responses (n = 51) represented 17 AfN-accredited undergraduate courses (35% of AfN-accredited universities in 2019). The majority (76%) of students had received an introduction, partaken in a module or received teaching on SDs throughout their whole degree. Students were predominantly environmentally literate, yet had a fragmented understanding of SDs, focusing on the environmental aspects of SDs. There was no correlation between SFL and reported sustainability content of university courses, highlighting a need for more effective teaching on sustainability topics. Additionally, no relationship between self-reported diet intake and SFL was found. Students identified a lack of knowledge and education as barriers preventing them from adopting sustainable practices in the present and future. To integrate sustainability into their future practice more consistently and effectively, nutrition students require more structured, holistic sustainability education and knowledge.</p>","PeriodicalId":48536,"journal":{"name":"Nutrition Bulletin","volume":" ","pages":"572-586"},"PeriodicalIF":3.3,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72211418","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}

The current study aims to better understand the relationship between impaired taste perception, fat consumption, higher BMI and obesity development by examining the combined association between CD36 SNPs, oleic acid (OA) detection threshold, and food habits among Indian participants. Furthermore, the relationship between oral fatty acid (FAs) sensitivity and taste physiology factors linked to inflammation and salivary proteins was considered. Participants with the minor allele (AA/AG) of CD36 (in both rs1527483 and rs1761667) consumed more fat, particularly saturated FAs (p = 0.0351). Salivary lipopolysaccharide, which causes inflammation, was significantly greater in non-vegetarians with a higher BMI (p < 0.05), and it exhibited a negative correlation (r = -0.232 and p < 0.05) with Ki67 gene expression, a marker for taste progenitor cells. A positive correlation (r = 0.474, p = 0.04) between TLR4 mRNA levels and the OA detection threshold was also observed.

Transaction and redemption records from 150 loyalty card-holding households, living in northern England, who had engaged with the top-up scheme, were analysed to assess the potential overall population impact. Using a pre-post study design, 133 of these households' records from 2021 were compared with equivalent time periods in 2019 and 2020. Records were linked to product, customer and store data, permitting comparisons using Wilcoxon matched-pairs sign-ranked tests and relationships assessed with Spearman's Rho. These analyses demonstrated that 0.9 more portions of FV per day per household were purchased during the scheme compared to the 2019 baseline (p = 0.0017). The percentage of FV weight within total baskets also increased by 1.6 percentage points (p = 0.0242), although the proportional spend on FV did not change. During the scheme period, FV purchased was higher by 0.4 percentage points (p = 0.0012) and 1.6 percentage points (p = 0.0062) according to spend and weight, respectively, in top-up redeeming baskets compared to non-top-up redeeming baskets with at least one FV item and was associated with 5.5 more HSV 'Suggested' FV portions (p < 0.0001).

Whilst there is broad agreement on the principles underpinning a healthy, sustainable diet, the interpretation of what it might mean in practice is widely debated. Misconceptions are common, including around the environmental impact of eggs and their place in a healthy, sustainable diet. Eggs are often categorised with other animal proteins such as beef, lamb, poultry, meat and dairy when reporting on the potential environmental impact of food and diets. However, the shift towards more planet-friendly diets demands a clear understanding of the evidence base on which such a diet should be based. This review evaluates scientific reports and peer-reviewed articles that have evaluated the environmental impact of hens' eggs in terms of greenhouse gas emissions (GHGEs), and land and water use and compared the impacts of eggs with those of other animal and plant proteins. This overview shows that eggs are responsible for less carbon, land and water use than other animal proteins, particularly beef and only slightly more than most plant proteins. Eggs are a nutritious, convenient and relatively inexpensive food, which traditionally has had an important place in the diet both in the United Kingdom and globally. It is therefore important to understand where they fit in terms of environmental impact and into advice on healthier, more sustainable dietary patterns.</p>","PeriodicalId":48536,"journal":{"name":"Nutrition Bulletin","volume":"48 3","pages":"400-410"},"PeriodicalIF":3.3,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10406251","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}
