This meta-analysis aimed to evaluate the effect of nut consumption on vascular endothelial function through the conduction of a comprehensive review of randomised controlled trials. We explored the major electronic databases for published RCTs examining the repercussions of nuts consumption on vascular endothelial function indicators in adults (>18 years). We used random-effects models to compute pooled estimates of weighted mean differences and confidence intervals. The protocol of the present study was registered in the international database of systematic review protocols (CRD42023472892). Nineteen articles, comprising 21 arms, were deemed eligible. According to the pooled estimations, eating nuts significantly improved flow-mediated dilation (FMD) (weighted mean difference (WMD): 1.12%, 95% CI 0.28 to 1.97, p < 0.05), and reactive hyperaemia index (RHI) (WMD: -0.04, 95% CI -0.07 to -0.00, p = 0.04). However, findings revealed that consuming nuts had no significant impact on pulse wave velocity (PWV), the index of augmentation (AIx), or heart rate. The endothelial function was considerably enhanced by nut consumption through the improvement of FMD, while the certainty of such evidence was assessed as very low.

This study aims to estimate the global prevalence rate and disease burden of zinc deficiency from 1990 to 2020 in children under 5 years old. Using data from the WHO Global Database on Child Growth and Malnutrition and the Global Burden of Diseases, Injuries, and Risk Factors Study, we analysed the prevalence, disability-adjusted life years (DALYs), and deaths attributable to zinc deficiency by sex across 204 countries and territories worldwide from 1990 to 2020. Globally, the prevalence rate of zinc deficiency decreased from 40 to 22% from 1990 to 2020. The age-standardised DALY rate of zinc deficiency decreased from 24.885 to 3.858 per 100,000 population from 1990 to 2019. Overall, the global prevalence of zinc deficiency and its associated disease burden in children under 5 years old declined from 1990 to 2020. Burundi and Central African Republic need effective interventions to alleviate the prevalence and disease burden of zinc deficiency.

Selenium-rich yeast (SeY) is a dietary supplement known to confer multiple health benefits, but its effects on HFD-fed ApoE^-/- mice were previously unclear. In this study, it was shown that the intervention of SeY could decrease the body weight (7.69%), as well as the levels of both TC and TG for livers (43.36 and 14.50%) and serum (25.34 and 28.67%). Conversely, the HDL-C levels were increased high to 190%, as well as the antioxidant capacity, reflected in the increased levels of the CAT, SOD, and GSH-Px in both the liver (16.93, 22.06, and 17.59%) and the serum (40.67, 113.76, and 19.83%). SeY could further regulate mRNA levels related to lipid synthesis and transport. Moreover, the anti-hyperlipidemic effects of SeY were manifested in enriching SCFAs-producing bacteria, and the cognitive impairment caused by HFD was also alleviated. Overall, all of the results indicated the effect of SeY in regulating abnormal lipid metabolism and developing functional dietary supplements.

Taurine is recognised for its neuroprotective effects, however, its potential role on cognition remains controversial. A meta-analysis of randomised controlled trials (RCTs) was conducted to evaluate the effects of taurine on cognition in both cognitively impaired and non-impaired populations. Electronic databases was searched up to January 2025 according to eligibility criteria. A total of 7 RCTs with 9 intervention trials involving 402 individuals were included. Taurine, administered alone or in combination with exercise training, did not exhibit significant effects in cognitive scores. Compared with therapeutic drugs alone, the combination of taurine and therapeutic drugs did not produce greater improvements in cognitive performance, however, subgroup analysis indicated that this combination resulted in significant enhancements in the Mini-Mental State Examination (WMD = 3.09, 95% CI: 2.29-3.90). Overall, the findings of the present meta-analysis do not provide sufficient evidence to support the efficacy of taurine supplementation in enhancing cognitive function.

Although plant-based analogues of animal products have become increasingly common, their sodium content has not been adequately investigated. The main aims of this study were to: (i) compare sodium content of cheese analogues, meat analogues, and tofu and tempeh sold in Italy with the relative WHO benchmarks (720, 250 and 280 mg/100 g, respectively); and (ii) evaluate the effectiveness of Nutri-Score in identifying products exceeding these benchmarks. Food labels from 430 meat analogues, 49 cheese analogues and 42 tofu and tempeh products were collected and analysed. Meat analogues (93%) and tofu and tempeh (57%) had the highest percentage of products exceeding the benchmark while cheese analogues had the lowest (20%). All subcategories in the meat analogues category showed a higher median sodium content than the benchmark, with cured meats having the highest level. Among cheese analogues, the grated cheese subcategory showed the highest median sodium content with all products exceeding the benchmark, while tofu and tempeh had the lowest median sodium content. The Nutri-Score algorithm did not consistently identify products with sodium levels exceeding the established benchmarks. This study highlights the need to reduce sodium content of such products and emphasises the importance of improving consumers' nutritional awareness.

The study aimed to evaluate the differences between generations and relationship between mindful and intuitive eating with body mass index (BMI), depression, stress, and anxiety. This cross-sectional study was conducted on 547 adults. Online questionnaire including Intuitive Eating Scale-2nd edition (IES-2), Mindful Eating Questionnaire (MEQ), and Depression, Anxiety, Stress Scale was performed. Gen Z scored highest for "unconditional permission to eat", and lowest for "interference" (p < 0.001). Baby Boomers demonstrated the lowest "conscious nutrition" scores compared to others (p: 0.002). Weak negative correlations were observed between IES-2 scores and BMI (r: -0.165, p < 0.001), depression (r: -0.194, p < 0.001), anxiety (r: -0.191, p < 0.001), and stress (r: -0.100, p: 0.020). MEQ scores were negatively correlated with BMI, depression, anxiety, and stress (r: -0.159, r: -0.364, r: -0.372, r: -0.360, p < 0.001). "Eating for physical rather than emotional reasons" showed negative correlation with depression, anxiety, and stress scores (r: -0.259, r: -0.249, r: -0.168, p < 0.001).

The Mediterranean diet (MD) has been recognised as a healthy and sustainable diet model. Despite this, current eating habits diverge significantly from established dietary recommendations, namely the MD among young university students. The eating habits of young people are characterised by a high consumption of energy-dense foods and a low consumption of vegetables and fruit. Thus, university canteen food services are essential in promoting a healthy and sustainable diet. This systematic review aimed to identify the strategies for promoting adherence to the MD and healthy diets in Higher Education food service. This systematic review was based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Of the 39 studies that were retrieved, all focused on strategies to improve healthy eating, and none specifically used the term "Mediterranean". Studies were conducted in different countries worldwide. Architectural nudges, discounts on healthy food and nutritional information were identified as successful strategies, especially among females and students with higher nutrition education. A combination of nudging strategies in food service is a promising way to promote healthier food habits.

Formulations based on a mixture of corn: lentil flours (70:30) (93.75%), salt (1.25%), sugar (5%), 5 or 20% of Hylon^® V, were fortified with 5 and 20% of fermented Cabernet Sauvignon grape skin or seed, and unfermented Chardonnay grape seed flours, and evaluated for their functional components. The incorporation of winemaking by-products increased the dietary fibre content. Soluble sugars and arabinoxylans content depended only on corn:lentil flours presence. The total starch content varied between 42 .55 g/100g to 58.41 g/100g and the highest concentrations of resistant starch were determined in formulations with 20% Hylon^® V. Total phenols, total flavonoids, and anthocyanins, were higher in all formulations with 20% fermented Cabernet Sauvignon skin or unfermented Chardonnay seed flours, regardless the content of corn:lentil flours. Winemaking by-products represent potential functional and prebiotic novel ingredients for new functional food products.
