This study examines the influence of fish oil on brain amyloidogenesis in hyperglycaemic Alzheimer’s disease animal models, emphasising the potential of omega-3 fatty acids in fish oil to prevent the development of Alzheimer’s disease. Thirty males of Wistar rats were divided into five groups: 1) control rats (NS); 2) rats supplemented with 3 g/kg of fish oil (NS+FO3); 3) rats injected via intraperitoneal (i.p) with Streptozotocin-Lipopolysaccharide (STZ-LPS); 4) rats injected with STZ-LPS (i.p) and supplemented with 1 g/kg of fish oil (STZ-LPS+FO1), and 5) rats injected with STZ-LPS (i.p) and supplemented with 3 g/kg of fish oil (STZ-LPS+FO3). The cerebral brain was extracted for examination, and the αβ precursor protein (APP) level was measured using an immunoassay kit, while αβ 42 expression was evaluated using immunohistochemistry staining. Brain amyloidosis-related genes were quantified using real-time Polymerase Chain Reaction (PCR). The results revealed that fish oil supplementation significantly increased APP levels and reduced αβ 42 accumulations in STZ-LPS rats. Moreover, the Apolipoprotein E, ε4 isoform (ApoE-4) and Beta-site APP-cleaving enzyme 1 (Bace-1) genes were downregulated while the Low-density lipoprotein receptor-related protein 1 (Lrp-1) gene was upregulated in STZ-LPS rats treated with fish oil, thereby elucidating the impact of fish oil on diminishing αβ buildup in the brain. Therefore, this study contributes to a growing body of evidence supporting dietary interventions as adjunctive strategies for the prevention or delay of Alzheimer’s disease progression in metabolic dysfunction.

This pilot study evaluated the effect of an online cooking intervention: Up for Cooking. Seventy-three Dutch families participated in four 1.5-hour sessions, before which they received ingredients and intervention materials. Parental questionnaires (pre-post) assessed food literacy skills (planning, selecting and making a healthy meal), knowledge and self-efficacy towards cooking and healthy eating (quantitative). Interviews assessed whether families changed their cooking behaviour at home (qualitative). A Wilcoxon Signed Rank test and inductive thematic coding were used. Thirty-nine parents completed questionnaires and eleven parents participated in interviews. Scores on food literacy items related to selecting and making a healthy meal improved significantly post-intervention. Parents’ knowledge of healthy eating and self-efficacy in cooking with their children also improved significantly. Interviews revealed an increased involvement of children in meal preparation and positive changes in family cooking behaviour. This online cooking intervention is a promising nutrition intervention, but implementation and long-term changes need further exploration.

This cross-sectional study evaluated the nutritional composition and labelling of commercial foods in Canada targeted to infants up to 18 months of age. Front-of-package labelling requirements were assessed based on daily values identified by Health Canada for saturated fatty acids, sugars, and sodium for children aged one year and older. Infant commercial food products were identified from online and in-person records of retailers across Canada. A total of 1,010 products were identified. Products aimed at older infants (12–18 months) contained significantly more calories, macronutrients, sugars, saturated fat, and trans fat compared to those targeted at younger infants (<12 months). In addition, 40% of products for children aged 12–18 months required a ‘high in sugar’ front-of-package label, while less required a ‘high in saturated fats’ (13%) and ‘high in sodium’ (5%) label. Organic products had higher added sugar and fibre, while they were lower in calories, total fat, saturated fat, and protein. Plant-based products, including vegetarian/vegan products, contained fewer calories, fat, saturated fat, trans fat, and protein, but more fibre. Gluten-containing products had more calories, macronutrients, sugar, fibre, and saturated fat. Non-GMO labelled products had more calories, carbohydrates, and sugar, but less saturated fat. Significant differences were observed for vitamins and minerals across food categories (p < 0.05). Our findings offer valuable guidance for parents, caregivers, and healthcare professionals on infant nutrition, highlighting the importance of selecting foods that align with infants’ specific dietary needs.

Sulforaphane (SFN), a bioactive compound derived from glucoraphanin in cruciferous vegetables such as broccoli, has been extensively studied for its therapeutic potential across diverse disease categories. SFN exerts its effects through well-characterised pathways, including the Keap1/Nrf2 axis, which regulates phase II detoxification enzymes, and epigenetic mechanisms such as histone deacetylase inhibition. This review evaluates clinical trials registered on ClinicalTrials.gov, focusing on those using SFN or broccoli-derived extracts.

As a result, we identified 84 trials, of which 39 have been published. Results suggest SFN’s potential in regulating redox and inflammatory pathways, improving metabolic and cardiovascular outcomes, and exerting anti-cancer and neuroprotective effects. For healthy subjects, SFN enhanced detoxification and reduced inflammation. In cancer patients, SFN showed promise in early-stage prostate and breast cancer, particularly in GSTM1-positive individuals, but had limited effects in advanced cases. For brain disorders, SFN demonstrated symptomatic improvements in autism spectrum disorder and cognitive benefits in schizophrenia but lacked robust biomarker integration. SFN had minimal impact on respiratory diseases but showed supportive roles in allergic rhinitis therapy. Metabolic disease studies revealed glycaemic control improvements in type 2 diabetes but no benefits for hypertension. Approximately 50% of completed trials remain unpublished, raising concerns about publication bias. While published results highlight SFN’s therapeutic potential, limited sample sizes and inconsistent outcomes underscore the need for more extensive, stratified trials. This review emphasises the importance of integrating mechanistic insights and precision medicine approaches to maximise SFN’s clinical utility.

Adolescents from low-income households are at increased risk of growth failures due to inadequate food intake. This cross-sectional study assessed dietary practices and nutritional status according to FANTA measurement standards. Among 610 randomly selected adolescents attending public primary schools in rural and semi-urban Kuyu district. Dietary diversity and anthropometric measurements (height, weight, and Body Mass Index) were collected and analysed using SPSS version 26 and WHO Anthro Plus software. The study population included 36% females and 69% semi-urban residents. Dietary analysis revealed that most adolescents consumed two or fewer daily meals, primarily cereals and legumes. Over 90% of the households consumed less than four food groups during the 7-day recall period. The anthropometric assessment showed significant undernutrition: 19% of early adolescent girls and 34% of late adolescent boys were underweight; 27.5% were stunted; 8% and 5.9% had moderate and severe undernutrition, respectively; and 13.8% exhibited thinness, with boys more affected (35%) than girls (10%). Additionally, 7% were overweight, and 64% presented single, double, or triple growth failures. Regression analysis showed that Children in female-headed households had 1.7 times higher odds of stunting, adolescent girls had 1.8 times higher odds of thinness, late adolescents had 70% lower odds of being overweight, and adolescents from households with off-farm activities had 4.5 times higher odds of being overweight. Inadequate meal frequency and limited dietary diversity contribute to the high prevalence of undernutrition among Kuyu district adolescents. A school feeding programme is strongly recommended.

This qualitative descriptive study aimed to explore dietary habits among healthcare workers during night shifts and to identify individual and environmental factors that influence their dietary behaviour during night shifts. Individual semi-structured interviews were conducted with twenty-five healthcare night female workers, which were recruited via email invitations from managers and posters placed in central workplaces at a university medical centre in the Netherlands. The interview protocol was developed following an integrated behaviour change model focusing on individual (I-Change model, i.e., awareness, motivation, intention, and ability) and environmental (Environmental Research framework for weight Gain prevention at environmental level (EnRG), i.e., physical, policy-related, economic, and sociocultural) factors. Inductive analyses were conducted to explore dietary habits, while deductive thematic analysis was applied to identify potential factors influencing dietary behaviour. Female healthcare workers in night shifts generally made poorer dietary choices during night shifts than during other shifts. Seven key themes were coded for dietary behaviour. Based on the domains of the integrated behaviour change model, four individual and five environmental key themes were established, within which 41 sub-themes were coded. Key individual factors included awareness (i.e., lack of knowledge about timing and type of consumption) and motivation (i.e., attitude and efficacy to eat healthy). Critical environmental factors included physical and sociocultural work environment, organisation of work, and lack of organisational policies. To conclude, future dietary interventions for healthcare night workers should target both individual behaviours and the workplace environment, with an emphasis on raising awareness and enhancing organisational policies to promote healthy dietary habits.

Although studies had suggested that monosodium glutamate (MSG) may serve as a salt substitute in processed foods, its market impact remains unclear. This study was aimed to: (1) identify MSG in ingredient lists, (2) compare sodium levels in products with and without MSG, (3) examine the association between MSG and other umami enhancers, and (4) assess manufacturers’ adherence to the Food Regulation 1985 for MSG declaration. An observational cross-sectional market survey was conducted during the Movement Control Order (June to September 2021) on 1076 processed foods from selected Malaysian hypermarkets, that were located within 10 km of the researcher’s residence to ensure accessibility amid the COVID-19 pandemic movement restrictions. Additionally, online platforms were used to supplement any missing data. Nutritional and ingredient information were collected from packaging, and foods were classified by using the FAO/WHO Food Standards CODEX Alimentarius. Over half (50.8%) of the surveyed products contained MSG. Results found that MSG-containing products had a significantly higher sodium levels (2812.2 ± 5191.4 mg/100 g) than those without (1372.2 ± 1541.4 mg/100 g) (p < 0.001). Additionally, 14.4% of MSG-free products were labelled as ‘No Added MSG’, while products with MSG were more likely to contain other umami enhancers (p < 0.001). Compliance with MSG declaration regulations was 61%. In conclusion, MSG was present in half of the surveyed products. MSG-containing products were more likely to have higher sodium content and include other flavour enhancers. Future research should analyse the actual MSG as well as sodium content and explore alternative sodium reduction strategies.

This pilot cross-sectional study, conducted in two public hospitals in Malawi, assessed gestational diabetes mellitus (GDM) in pregnant women attending antenatal clinics and compared their dietary quality and food group consumption before and during pregnancy. The study targeted women aged 18 to 49 years within 24 to 28 weeks of gestation. GDM was diagnosed according to the International Association of Diabetes and Pregnancy Study Group criteria and assessed dietary quality before and during pregnancy using a 30-day qualitative food frequency questionnaire. We compared changes in dietary quality and specific food group mean scores using paired t-tests at p < 0.05. Of the 508 women enrolled, 22.7% were diagnosed with GDM. The overall diet quality significantly decreased during pregnancy compared to before; a similar trend was observed in women diagnosed with GDM compared to those without GDM (p < 0.0001). Among women with GDM, the mean score of the following food groups significantly (p < 0.05) decreased during pregnancy: cruciferous vegetables, deep orange vegetables and tubers, citrus fruits, deep orange fruits, other fruits, nuts and seeds, poultry, fish, low fat dairy, whole grains, and liquid oils and significantly (p < 0.05) increased in the following food groups; red meat, processed meat, sugar-sweetened beverages, sweets, sugary snacks and ice cream. In conclusion, GDM is prevalent in Malawian women enrolled in this study and is coupled with inadequate dietary quality, especially during pregnancy. Since dietary quality is pivotal to GDM management, more in-depth longitudinal dietary studies are needed to inform nutritional interventions to prevent and better manage GDM.

Statins are effective drugs for lowering hypercholesterolemia and preventing cardiovascular diseases. They can cause various side effects, in particular statin-associated muscle symptoms (SAMS) associated with mitochondrial dysfunction and micronutrient depletion. The aim of this systematic review and meta-analysis was to investigate the efficacy of a supplementation with Coenzyme Q10 (CoQ10) against SAMS in statin-treated patients. A systematic literature search was performed in Medline and Cochrane Library in August 2024. Studies were selected for a meta-analysis according to the following criteria: randomised controlled trials (RCTs), adults taking statins (any type and dose), supplementation of CoQ10, a comparable control group, and muscle pain as outcome criterion. Cochrane Risk of Bias tool was used for bias assessment. Seven RCTs with 389 patients in total were included in this meta-analysis. The selected studies included 35 to 76 patients and had a duration ranging from 30 to 90 days with CoQ10 dosages ranging from 100 to 600 mg per day. Results show a significant reduction of SAMS in four trials and no significant change in three trials. Overall, a significant reduction in SAMS, measured as pain intensity, after CoQ10 supplementation was found: weighted mean difference (WMD) −0.96 (95% Confidence Interval −1.88; −0.03), p < 0.05. Supplementation of CoQ10 can reduce muscle pain in patients with SAMS, which is relevant for their well-being and treatment continuation. More research is needed for evidence-based recommendations.

There is increased interest in self-selected exclusionary diet patterns, specifically vegetarian, vegan, and gluten-free (GF) diets, but there is a lack of research exploring the beliefs and behaviours surrounding these diets in Canadians capable of bearing children (CCBC). The goal of this study was to explore the beliefs and behaviours of CCBC who follow vegetarian, vegan, and/or GF diets using mixed methods. A self-administered online Qualtrics™ survey containing 102 questions was conducted using open text and closed format questions. Continuous variables were summarized using mean and standard deviation while percentages were used to summarize categorical variables. Qualitative data was analysed using thematic analysis. A total of 271 CCBC between 18–45 years of age were analysed, with 27%, 22%, and 3.7% indicating they followed a vegan, vegetarian, and/or GF diet, respectively. Three main themes emerged that influenced CCBC beliefs about their chosen diet. The belief that these diets are healthy or could impart health in some way, was the main reason for following their chosen diet, especially in those who identified as vegetarian. Ethical/moral concerns, primarily around animal welfare and the environment, was the second theme for following their chosen dietary pattern, especially amongst those who identified as vegan. Perception of social judgement in the forms of criticism, guilt, and isolation were noted by some CCBC, with family, friends, and colleagues interacting differently with them because of their dietary choices. These findings serve to enhance our understanding of the beliefs and behaviours of CCBC who choose to follow exclusionary diets.

Male volleyball athletes may be at risk of inadequate energy and carbohydrate intake. This may increase their risk of relative energy deficiency in sport (REDs) and impair a variety of physiological and psychological systems involved with performance and health. This study explored the eating behaviours and diet quality of international elite volleyball male athletes and their association on hormones associated with acute energy deficit and primary serum REDs indicators outlined in the International Olympic Committee REDs Clinical Assessment Tool 2. Methods: Using a retrospective design, 30 male athletes from a national indoor volleyball programme were assessed using DXA bone mineral density, hematological analysis, anthropometry, restrained eating behaviour via the Three-Factor Eating Questionnaire-R18 and the Athlete Diet Index (ADI) questionnaire. Results: All participants met or exceeded dietary recommendations for health and sport with ADI mean score of 95.2/125 ± 10.5. Restraint eating was inversely associated with insulin (r = − 0.37; p  < 0.05). Both the ADI total and core nutrition sub-scores were inversely associated with free-triiodothyronine (r = − 0.58; p < 0.01) but not with total testosterone, insulin or leptin. Conclusion: Male volleyball athletes at risk of inadequate energy intake may not necessarily demonstrate signs of poor diet quality.

Accurate assessment of an individual’s diet is vital to study the effect of diet on health. Image-based methods, which use images as input, may improve the reliability of dietary assessment. We developed an iOS application that uses computer vision to identify food from images. This study aimed to assess the accuracy of energy intake (EIapp) estimates from the application by comparing them to estimated energy expenditure (EE) and to the EI estimates from a validated dietary assessment tool, the 24-h recall (EIrecall). Participants were recruited from a randomised controlled trial called He Rourou Whai Painga. Participants recorded all intake over 7 d using the application, which provided a mean daily EI; this was compared to the EI estimated by two 24-h recalls. The EI from the application and the recalls were compared to EE, estimated using indirect calorimetry and wrist-worn accelerometry. EI estimates from the application and the 24-h recalls were lower than EE, with a mean bias of -1814 kJ (95% CI -3012 to -615, p = 0.005) and -1715 kJ (95% CI -3237 to -193, p = 0.029), respectively. The mean bias between EI from the application and the 24-h recall was 783 kJ (95% CI -875 to 2441, p = 0.33). This suggests that the EI estimates from the application are comparable to the 24-h recall method, a validated and widely used tool in nutritional research.

This paper examines associations between maternal exposure to a radio programme, Bhanchhin Aama (Mother Knows Best), and the programme’s most promoted maternal and child nutrition-related practices, using the Nepal Demographic and Health Survey (NDHS) from 2022. We limited our sample to mothers of children less than 2 years (n = 1,933). The primary exposure variable was whether the mother listened to the Bhanchhin Aama radio programme. The five primary outcomes were: maternal dietary diversity, maternal use of modern family planning methods, exclusive breastfeeding (EBF) of children less than 6 months, dietary diversity among children 6 to 24 months, and participation in growth monitoring and promotion among children 0 to 24 months. Descriptive analyses followed by logistic regression models, adjusted for potentially confounding factors and clustering, were conducted. Maternal exposure to Bhanchhin Aama was associated with nearly 70% higher odds of meeting both maternal (OR: 1.67; p: <0.001; CI: 1.26–2.21) and child minimum dietary diversity (OR: 1.70; p: 0.005; CI: 1.18–2.45), as well as 83% higher odds of a child participating in growth monitoring and promotion (OR: 1.83; p: 0.001; CI: 1.28–2.63). No associations were found for use of modern family planning methods and EBF. These findings suggests that radio programmes may be an effective tool to improve some maternal and child nutrition-related practices. Further research is needed to understand why certain behaviours are modifiable from this type of intervention versus others that are not and for which population groups this intervention would be most effective.

Food insecurity is a global issue. The objective is to summarise the literature identifying the main outcomes related to out-of-school hours interventions that provide food for low-income families with school-aged children, how they impact school-aged children and their families, and to identify gaps in knowledge. This review covered the main types and dimensions proposed in the literature. One author independently selected the studies, and an independent reviewer randomly reviewed them. Any paper meeting the inclusion criteria was considered regardless of geographical location. Papers were predominantly from the US, UK and Australia, including school-aged children from low-income families. Ninety-four articles were included relating to holiday clubs (n = 38), breakfast clubs (n = 45) and after-school clubs (n = 11). Key outcomes were healthy eating, academic, social, physical activity, nutritional education and financial outcomes. Clubs were consistent regarding the positive social and financial outcomes. There was variation in the primary aim, either to improve healthy eating or to feed children, regardless of nutritional quality. None of the studies reported children’s health outcomes. This review identified the key outcomes of interventions for low-income families outside of school hours in the literature. It highlights the consistent positive social outcomes across the three intervention types and the discrepancy in the nutritional value of the food provided. Few studies examined the attainment impact of holiday clubs, with no evidence on how they could impact term-time attendance. This highlights the need to analyse secondary data to understand further the attainment and attendance impact on children attending these interventions over time.

The multilevel dimensions of sustainable diets associating food systems, public health, environmental sustainability, and culture are presented in this paper. It begins by defining sustainable diets as those that are healthful, have low environmental impacts, are affordable, and culturally acceptable. The discussion includes the history of research on sustainable diets, from initial studies focused on environmental impacts to more recent, comprehensive frameworks that integrate affordability, cultural relevance, and nutritional adequacy as key dimensions of diet sustainability. In addition, the paper highlights recent innovations, such as the Planetary Health Diet of EAT–Lancet and the SHARP model, and the conflicts and optimum trade-offs between sustainability and nutrition, particularly within low- and middle-income countries. Case descriptions of Mediterranean Diet with a focus on Traditional Lebanese Diet, and African Indigenous Foods demonstrate culturally confined dietary patterns associated with sustainability objectives. These examples show that sustainable diets are not a single set of prescriptions, but a series of multiple pathways that are shaped by local food environments, ecological belts, and sociocultural heritages. The paper also describes major policy and governance activities necessary to promote sustainable diets. Finally, the paper addresses measurement challenges and advocates for better indicator options to measure sustainable food systems in all their facets and for participatory and context-specific approaches. The discussion concludes that fairer and culturally diverse inclusion strategies, system change, and political determination are imperative in achieving sustainable diets. Diets able to sustain are posited as agents capable of driving the 2030 agenda, enhancing planetary health and social integrity.

Dietary fibre can modify colostrum and milk composition in sows. Bile acids (BA) aid in fat digestion and lipid absorption and are important signalling molecules for the digestive tract. The aim of this study was to determine BA concentration in colostrum from sows fed two different sources of dietary fibre during gestation and lactation and from the intestinal digesta of their 4-6-days-old suckling offspring. Twenty sows were fed diets enriched with either 15% high-fermentable sugar beet pulp (SBP, n = 10) or 15% low-fermentable lignocellulose (LNC, n = 10). Sow colostrum, piglet gallbladder content, ileum and colon digesta were assessed for BA using high-performance liquid chromatography coupled to triple-quadrupole mass spectrometry. In colostrum, lithocholic acid and oxolithocholic acid were higher in sows fed SBP vs. LNC (p = 0.005 and p = 0.003, respectively), while 3α,7α,12α-trihydroxycholestanoic acid and glycohyodeoxycholic acid were higher in colostrum from sows fed LNC vs. SBP (p = 0.039, p = 0.002, respectively). In the piglet bile, cholic acid and taurodeoxycholic acid were higher in SBP vs. LNC group (p = 0.02, p = 0.001, respectively), while taurochenodeoxycholic acid was higher in LNC vs. SBP group (p = 0.035). In the piglet ileum digesta, lithocholic acid was higher in SBP vs. LNC (p = 0.015). In the piglet colon digesta, lithocholic acid and ursodeoxycholic acid were higher in SBP vs. LNC (p = 0.001 and p = 0.007, respectively). Addition of specific dietary fibres to sow diets differentially influences the BA in colostrum. Dietary fibres in sow diets can impact on the intestinal BA composition in piglets with a possible consequence on the digestive physiology and health in the offspring.

This study aimed to develop and validate a questionnaire that investigates sugar-related eating behaviour, excessive consumption, and addictive-like eating. This questionnaire was validated using a rigorous process assessing content validity, face validity, reliability testing, feasibility testing, and construct validity. Spearman’s correlation coefficients and Cronbach’s alpha were used to assess reliability. Feasibility testing was used to further validate and confirm the scoring/categorisation of ‘low’, ‘medium’, and ‘high’ scorers for use in future research. Exploratory factor analysis and reliability analysis were used to determine underlying latent factors and assess construct validity. Content validity was assessed by health professionals (n = 16), face validity was assessed by the lay public who had no expertise in nutrition or addiction (n = 20). Reliability (n = 54), repeat reliability (n = 50), and feasibility (n = 113) testing were assessed with a sample from the lay public. Spearman’s correlation coefficients were in the range of 0.58–0.91 and were statistically significant (P < 0.001), indicating good temporal stability within the questionnaire. Cronbach’s alpha coefficients were in the range of 0.62–0.93, indicating good internal consistency. Feasibility testing confirmed the use of calculating an ‘average total score’ from the data set and splitting the data set into tertiles: low, medium, and high scorers. Exploratory factor analysis confirmed three latent factors: F1: Compulsive Eating; F2: Comfort Eating; and F3: Withdrawal. Results suggest the questionnaire is highly reliable and was successfully validated. This questionnaire can be used in research to investigate problematic and addictive-like eating behaviour and its effects on ill health.
