By 2030, the world population is projected to reach approximately 9.7 billion. One of the core objectives of the global sustainable development goals (SDGs), adopted from the 1996 World Food Summit, is to eradicate hunger by that time, meaning ensuring food security for all. The Food and Agriculture Organization (FAO) defines food security as follows: “Food security exists when all people, at all times, have physical and economic access to sufficient, safe, and nutritious food that meets their dietary needs and food preferences for an active and healthy life.” Conceptually, it is posited that food security can be understood as a nexus of four elements: Food security = Availability + Access + Utilization + Stability of a food system. This study focused specifically on the food availability component of food security. It addresses a critical gap in the existing literature: the limited understanding of the role farmworkers and their families play in sustaining food systems. Specifically, it explores how the children of Haitian farmworkers in the United States perceive agricultural labor through the lens of their family’s experiences, including their personal willingness to engage in it and their advocacy for others to pursue such work. Although qualitative in nature, this study employed the Political Economy of the Food System, also referred to as Agrifood Systems Theory or the Political Ecology of Food Systems, as its guiding theoretical framework, as it aligns closely with the study’s objectives. The data were collected between December 2022 and June 2023. The sample consisted of eight young adults (ages 18 to 29), all of Haitian descent. Overall, the findings indicated that participants commonly reported feeling a sense of inferiority and a lack of interest in and respect for farmwork as a profession during their upbringing, particularly in comparison to peers from non-farmworker households and those outside of their immediate communities. This sense of inferiority was attributed to several factors, including their upbringing, the inherent vulnerability associated with farm work, and the long-term physical toll agricultural work had on both themselves and their parents. The study’s findings carry important implications for practitioners, scholars, policymakers, and all stakeholders involved in achieving food security. They underscore the urgent need to reform labor policies and improve the conditions surrounding farm work, making it a more appealing, dignified, desirable, and sustainable occupation in the face of a growing world population.

Background/Objectives: Poor dietary habits remain a significant public health concern, highlighting the need to promote healthy and sustainable eating patterns, especially in childhood and adolescence. This study assessed the eating habits of primary school children in the Tagus Lezíria region, focusing on adherence to the Mediterranean Diet (MD), recognized for its health and environmental benefits. Methods: The KIDMED index (Mediterranean Diet Quality Index for children and adolescents) was applied to 435 children, the vast majority (97.7%) aged 6–10 years. Results: The data showed that 64.6% of participants exhibited high adherence to the MD, 32.0% medium, and 3.5% low adherence. Despite these encouraging levels, several gaps were identified: 80% of the children did not meet the recommendation for regular nut consumption (≥2–3 times/week), 44% consumed legumes less than once a week, and 43% failed to eat vegetables more than once a day. Regarding demographic factors, no significant differences were observed in overall adherence categories; however, differences emerged in specific eating behaviours. For example, girls consumed more vegetables and cereals than boys, and children in rural areas consumed less dairy than those living in urban settings. Conclusions: These findings emphasize the importance of reinforcing targeted school-based educational interventions to promote healthier dietary behaviours, particularly increased consumption of fruits, vegetables, fish, pulses, and nuts. Strengthening children’s adherence to the MD from an early age may contribute to improving their health and fostering sustainable eating practices. Full article

Background/Objectives: Dietary treatment in phenylketonuria consists of a phenylalanine-restricted diet supplemented with a phenylalanine-free medical formula (Phe-FF). During the first six months of life, phenylalanine requirements can be met with breast milk (BM) or infant formula (IF). Despite all the benefits breastfeeding confers, it is often discontinued upon diagnosis of phenylketonuria, so more evidence is needed to support it. This study aimed to compare the assessments of nutritional status and metabolic control in infants with hyperphenylalaninemia/phenylketonuria who received BM, IF, or a combination of both as sources of intact protein, in addition to Phe-FF. Methods: A retrospective observational study was conducted in hyperphenylalaninemia/phenylketonuria patients between 0 and 6 months of age. Three groups were compared depending on the source of intact protein ingested: (1) BM + Phe-FF; (2) IF + Phe-FF; (3) mixture of BM and IF (BM + IF + Phe-FF). At each clinic visit, an anthropometric assessment and phenylalanine blood levels were analyzed. Results: 185 nutritional and metabolic assessments were included. The lowest median phenylalanine blood concentration was observed in the BM + Phe-FF group (129 µmol/L, interquartile range [IQR]: 39.5–232.5). In the BM + Phe-FF group all assessments were classified as eutrophic: −0.09 (SD ± 0.78); a statistically significant difference was observed between the BMI Z-Score of BM + Phe-FF and BM + IF-Phe-FF (p = 0.036). No statistically significant differences were observed in length/age Z-Score. Conclusions: Our results indicate that BM is the best option as a source of intact protein for children under 6 months of age with hyperphenylalaninemia/phenylketonuria, to maintain an adequate nutritional status and metabolic control.

Early-onset colorectal cancer (EOCRC) is emerging as a significant global health concern, particularly among individuals under the age of 50. This alarming trend has coincided with an increase in the consumption of processed foods that often rely heavily on synthetic preservatives. At the same time, these additives play a critical role in ensuring food safety and shelf life. Growing evidence suggests that they may contribute to adverse gut health outcomes, which is a known risk factor in colorectal cancer development. At the same time, synthetic preservatives serve essential roles such as preventing microbial spoilage, maintaining color, and prolonging shelf life. Natural preservatives, on the other hand, not only provide antimicrobial protection but also exhibit antioxidant and anti-inflammatory properties. These contrasting functions form the basis of current discussions on their safety and health implications. Despite their widespread use, the long-term health implications of synthetic preservatives remain inadequately understood. This review synthesizes recent clinical, epidemiological, mechanistic, and toxicological data to examine the potential link between synthetic food preservatives and EOCRC. Particular focus is placed on compounds that have been associated with DNA damage, gut microbiota disruption, oxidative stress, and chronic inflammation, which are the mechanisms that collectively increase cancer risk. In contrast, natural preservatives derived from plants and microbes are gaining attention for their antioxidant, antimicrobial, and possible anti-inflammatory effects. While these alternatives show promise, scientific validation and regulatory approval remain limited. This review highlights the urgent need for more rigorous, long-term human studies and advocates for enhanced regulatory oversight. It advocates for a multidisciplinary approach to developing safer preservation strategies and highlights the importance of public education in making informed dietary choices. Natural preservatives, though still under investigation, may offer a safer path forward in mitigating EOCRC risk and shaping future food and health policies. Full article

Background: Foods containing nutraceuticals from the mineral element group are being developed to compensate for the problem of deficiency in billions of people around the world. This research focuses on essential elements of patented cereal-based mixtures to complement the deficiencies of these elements and, at the same time, assesses their safety in terms of toxic elements in the human diet. Methods: The mineral and trace element contents in the mixtures were determined using the ICP-MS method with a subsequent evaluation of the contributions of the mixtures to the essential and toxic reference values based on dietary intakes and exposures for adults at 60, 80 and 100 kg of adult body weight and a portion size of 50 g. The potential health risk was evaluated using a metal pollution index. Results: The concentrations of minerals and trace elements in the cereal-based mixtures analyzed were as follows: K (up to 4150 µg/g) ≥ P > Mg > Ca > Na > Fe > Zn > Mn > Cu > Al > Ba (up to 4.40 µg/g) > Sr (up to 480 ng/g) ≥ Ti ≥ Ni > Ce ≥ Co > As ≥ Cs > Ag ≥ Li > Se > Be > Cr > Tl > Pb ≥ Hg > Ho > Cd > Sn (up to 1.12 ng/g). The mixtures contribute significantly to the reference values for Mn, Cu, Zn, Fe, and P for adults. Individual dietary exposure values of toxic elements for adults weighing 60 kg decrease in this order: Al (10.1 µg/kg bw/day) > Ni (362 ng/kg bw/day) > As ≥ Pb > Ag > Hg > Cd > and Sn (0.93 ng/kg bw/day). Conclusions: In terms of Regulation (EU) No 1924/2006 of the European Parliament and of the Council on nutrition and health claims made on foods, the cereal-based mixtures could be labelled “source of” Mn, Cu, Zn, Fe, and P when their contributions to the reference values exceeded 15%; in addition, “low sodium/salt” or “very low sodium/salt” can be applied. The mixtures contribute insignificantly to the toxic reference values of Al, Sn, Hg, Cd, Ni, and Ag, and the exposure values of Pb for developmental neurotoxicity, nephrotoxicity, and cardiovascular effects were considered safe. Regarding the metal pollution index of mixtures, there is no concern for potential health effects. Cereal-based mixtures are suitable for use in the food industry as a potential source of beneficial micronutrients for the human diet, although bioaccessible studies should not be neglected.

Background/Objectives: Dairy and soybean are important potential dietary sources of bone health. However, their comparative effectiveness and the role of specific components remain unclear. In this network meta-analysis (NMA), we aimed to compare the effects of various dairy and soy products (food level) and their key bioactive components (component level) on bone health in healthy women. Methods: We systematically searched PubMed, Embase, Cochrane Library, and Web of Science (up to 28 February 2025) for randomized controlled trials. A frequentist random-effects NMA was used to compare interventions for lumbar spine (LS) and total body (TB) bone mineral density (BMD) and bone turnover markers [osteocalcin (OC), deoxypyridinoline (DPD)]. Mean differences (MDs) and 95% confidence intervals were pooled. Interventions were ranked using the surface under the cumulative ranking curve (SUCRA). Results: Sixty RCTs involving 6284 participants (mean age: 54.2 years) were included. At the food level, no dairy or soy interventions significantly improved outcomes versus control, although milk + yogurt ranked numerically highest based on SUCRA values. At the bioactive-component level, the combination of casein + whey protein (MD 0.04 g/cm², 95% CI 0.01–0.06) and soybean protein (MD: 0.03 g/cm², 95% CI: 0.01–0.05) significantly increased TB BMD. Whey protein alone (SUCRA 74.4% for LS BMD) and casein + whey protein (SUCRA 86.3% for TB BMD and 75.9% for DPD) were among the highest-ranked interventions for bone health. Conclusions: The combination of milk and yogurt may be relatively promising among dairy products for bone health. Whey protein appears to be a key bioactive component beneficial for women’s bone health. Full article

Background: The prevalence of dental caries has increased among children, largely due to nutritional habits or inadequate access to dental care. The present study aimed to investigate the prevalence of dental caries associated with various factors that lead to their appearance, such as food intake and body composition, among Romanian school-age children from two counties, Bistriţa Năsăud and Mureş. Methods: This cross-sectional study included 1100 children aged 6–10 years from two Romanian counties. Dental caries experience was assessed using the DMFT and dmft indices based on WHO criteria. Dietary intake and oral health behaviors were evaluated through a food frequency questionnaire completed by parents. Associations between dietary variables and dental caries were assessed using independent sample t-tests and Mann–Whitney U tests. A binary logistic regression model was used to estimate the likelihood of caries in the permanent dentition (DMFT > 0), with covariates including county, parental education, daily sugar intake, consumption of dairy products, body mass index (BMI), and waist-to-height ratio. Results: It was found that the children who daily consume cheese recorded a DMFT value lower than the children who did not consume (p < 0.05). Moreover, those who consume sugary foods recorded higher values of DMFT as compared with those who did not (p < 0.05). The body weight, BMI, and waist circumference are positively correlated with DMFT, but negatively with dmft (p < 0.05). The overall prevalence of caries was 79.8% in primary dentition and 63.6% in permanent dentition, with slightly higher rates observed in Bistriţa-Năsăud County compared to Mureş. It seems that the predictors of the caries’s presence among children include the mother’s education level, sugar intake frequency, and body fat ratio. Conclusions: Based on significant associations found, one can affirm that the dental caries of the Romanian school-age children is due to sugary food intake and body composition. In addition, the direct relationship between dental caries and childhood obesity showed through the correlation of BMI and dental health indices denotes that school-age children should reduce sugary foods and increase dairy products.

Background: Oxidative stress (OS) and inflammation are interconnected processes with significant roles in various chronic diseases, particularly those associated with aging, such as metabolic syndrome (MetS). Recent evidence suggests that walnuts (from Juglans regia L.), due to their rich content of phytochemicals, have antiaging potential by attenuating OS and chronic low-grade inflammation, known as inflammaging. Objectives: We aimed to assess the impact of daily walnut consumption for 4 weeks on biomarkers of OS and inflammation in a cohort of middle-aged individuals at risk of developing MetS. Methods: In this crossover randomized controlled trial (RCT), 22 participants (mean age: 48.81 ± 4.3 years) underwent two 28-day dietary interventions separated by a one-month washout period. One intervention period included daily consumption of 45 g of walnuts, while the other (control period) involved a normal-calorie diet without walnuts. Catalase (CAT) and glutathione peroxidase (GPx) activities, total antioxidant capacity (TAC), and interleukin (IL-1β, IL-6, IL-8) and tumor necrosis factor alpha (TNF-α) levels were determined from serum before and after each intervention period. Results: Assessment of changes obtained for the selected biomarkers following the walnut and control-diet periods (final-baseline) showed slight changes, but without any statistical significance, among the 20 participants included in the analysis. Conclusions: This first RCT targeting a group of middle-aged adults at risk of developing MetS shows that short-term (4 weeks) daily walnut consumption did not significantly alter oxidative stress and inflammation parameters, thus potentially contributing to the maintenance of cellular homeostasis. Further research is needed to investigate the impact of daily walnut consumption over a longer period (>3 months) on oxidative and inflammatory status in the middle-aged population and its potential to positively impact MetS biomarkers.

This study investigated the oral microbiome of horses maintained on a high soluble carbohydrate diet based on sugarcane, in comparison to those fed a pasture-based diet composed of Cynodon spp., aiming to identify associations between dietary intake, the composition of oral microbial communities, and the occurrence of dental caries and diastemata. A total of 20 healthy horses, both male and female, with an average age of 9 ± 3 years and weight of 400 ± 100 kg, without a defined breed, were selected. They were divided into two groups: the High Soluble Carbohydrate Group (HSCCG), consisting of 10 horses fed sugarcane for at least 3 years, and the Low Soluble Carbohydrate Group (LSCCG), consisting of 10 horses fed pasture with Cynodon spp. Dental examinations were performed using an adapted oral endoscope to assess caries and diastemata, and saliva samples were collected for microbiota analysis. Statistical analyses included a Student’s t-test and Mann–Whitney test, with significance set at p < 0.05. Horses in the HSCCG had a higher presence of peripheral caries (p = 0.001), as well as differences in the degree (p = 0.010), class (p = 0.05), and presence of diastemata. Microbial diversity indices (Chao, inverse Simpson, and Shannon) showed no significant differences, but the relative abundance differed (p = 0.003). Linear Discriminant Analysis revealed distinct microbial profiles: Candidatus Saccharibacteria and Bacteroidetes were more abundant in the HSCCG, while Cyanobacteria_Chloroplast and Proteobacteria dominated in the LSCCG. Over 35 genera differed significantly between groups. The study concludes that diet plays a significant role in shaping oral microbiota and influencing the development of dental caries in horses.

Objectives: Skin aging, often accelerated by dietary advanced glycation end products (AGEs), poses both cosmetic and health challenges. This study explores the protective effects of hydroxytyrosol (HT), a potent antioxidant found in olives, against AGEs-induced skin aging in mice. Methods: A total of forty-eight 8-month-old specific pathogen-free (SPF) male C57BL/6J mice were randomly assigned to one of four groups: control, model, low-dose hydroxytyrosol (HT25), and high-dose hydroxytyrosol (HT50). An additional group of six 6-week-old SPF male C57BL/6J mice served as the youth group. The experimental period lasted 16 weeks. Following the intervention, skin, serum, and ileum samples were collected. Results: The results demonstrated that HT50 significantly increased skin moisture, epidermal thickness, and dermal thickness (p < 0.05). HT50 also significantly elevated hydroxyproline levels as well as superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) activities in the skin while reducing malondialdehyde (MDA) content (p < 0.05). Furthermore, HT50 significantly reduced the levels of interleukin-6 (IL-6), interleukin-1β (IL-1β), and tumor necrosis factor-α (TNF-α) (p < 0.05). Regarding intestinal integrity, hydroxytyrosol intervention (either HT25 or HT50) significantly increased the positive staining ratios of zonula occludens-1 (ZO-1) and occludin in the ileum (p < 0.05). Conclusions: HT improves skin hydration, thickness, and collagen levels while reducing oxidative stress and inflammation. Notably, HT also enhances intestinal barrier function, suggesting a role for the gut–skin axis. These findings highlight HT’s potential as a natural intervention for skin aging. Full article

Introduction: Consumption of ultra-processed food (UPF) is associated with poor diet quality and a risk for non-communicable diseases (NCDs). This study explores the energy contribution of NOVA foods and the nutrient gaps. Methods: The study sourced data from the previous Ethiopian National Food Consumption Survey (NFCS). It covered 8254 households, 8254 women of reproductive age (15–45 years old), and 7272 children (6–45 months old). Results: The most consumed UPF in children were biscuits, cookies, soft drinks, and semi-solid palm oil; while cow and human milk, whole wheat bread, a range of legumes, tubers, and cereal-based foods were among NOVA1. In both children and women, the largest dietary energy intake was from NOVA1 (74.6% and 79.0%), processed culinary ingredients (18.3% and 14.0%), processed foods (1.9% and 3.5%), and UPF (5.1% and 3.5%), respectively. Higher intake of energy from UPF was found in urban residences, wealthier households, and women with higher education. However, NOVA1 was more dominantly consumed in rural than in urban areas. Micronutrient and macronutrient gaps were observed compared to the recommended nutrient intake (RNI). The intake of fruits and vegetables was also considerably low compared to the WHO recommendation (≥400 g/day for adults, and ≥250 g/day for children). Conclusions: Adequate intake of micronutrients, fruits, and vegetables is essential to meet the RNI and could have reduced existing body micronutrient deficiencies, such as vitamin A, zinc, iodine, calcium, vitamin D, and selenium prevalence. Whether UPF intake in urban areas is associated with insufficient availability and access to NOVA1 foods or just due to the higher provision of UPF and gained popularity needs additional investigation. Further study is recommended to simulate the impact of increased fruits and vegetables and/or reduced intake of selected UPF, salts, and oils on NCD markers or mortality in the country. Full article

With the global aging population, skeletal muscle aging has threatened to elderly health, making dietary interventions for age-related muscle decline a research priority. Lycium barbarum, a traditional food and medicinal herb, was used in the study to prepare Lycium barbarum water (LBW). This experiment was conducted in animals and included four groups: young control (C-Young), aged control (C-Aged), young LBW-drinking (G-Young), and aged LBW-drinking (G-Aged). Assessments covered skeletal muscle mass, cross-sectional area, and exercise ability to compare health status. The study measured mRNA expression of Atrogin-1 and MuRF-1 from the Forkhead Box O (FOXO) pathway, advanced glycation end products (AGEs) and senescence-associated β-galactosidase (SA-β-gal), oxidative stress levels via superoxide dismutase (SOD), malondialdehyde (MDA) and glutathione (GSH), inflammatory levels through interleukin-10 (IL-10) and tumor necrosis factor-alpha (TNF-α), and applied untargeted metabolomics to profile metabolic alterations. Optimal LBW was achieved at 80 °C with a 1:10 (w/v) solid-liquid ratio. In aged mice, long-term LBW administration improved exercise capacity, reduced muscle atrophy, and increased muscle mass, alongside decreased aging-related markers, alleviated oxidative stress, and modulated inflammatory levels. Additionally, metabolomics confirmed age-related oxidative stress and inflammation. Long-term LBW consumption alleviates age-related skeletal muscle dysfunction via multi-target regulation, holding promise as a natural nutritional intervention for mitigating skeletal muscle aging.

Background/Objectives: In India, according to the National Family Health Survey (NFHS-5), 36% of children under five years old are stunted, 19% are wasted, and 32% are underweight, indicating widespread undernutrition. Methods: A randomized controlled trial was conducted between August 2023 and May 2024 (CTRI/2023/04/051566), enrolling 223 undernourished Indian children, randomly assigned to the oral nutritional supplement (ONS) + dietary counseling (DC) (n = 111) arm or the dietary counseling (DC) arm (n = 112). This study recruited both male and female subjects with picky eating habits and with height-for-age (HAP) and weight-for-height percentiles (WHP) below the 25th percentile according to the WHO Growth Standards and Growth Reference. Outcomes assessed were anthropometric indices, dietary intake, sick days, and nutrient adequacy. Data were analyzed using ANCOVA, with statistical significance at p < 0.05. Results: At 6 months, the ONS + DC group showed significant improvements compared to DC in HAP (12.1 vs. −0.4, LS Mean difference [95% CI], 13.3 [11.13, 15.48], p < 0.0001), and WAP (9.7 vs. 2.3, LS Mean difference [95% CI] 7.9 [5.07, 10.78], p < 0.0001). MUACP significantly increased in the ONS + DC group (11.1 vs. −1.0 in DC, LS Mean difference [95% CI], 11.1 [5.28, 16.99], p < 0.0001). Dietary intake of carbohydrates, proteins, and energy was significantly higher in the ONS + DC group at 3 months, with sustained improvements at 6 months. By 6 months, the ONS + DC group showed a significantly higher protein-to-energy intake ratio compared to the DC group (0.0027 vs. −0.0003, LS Mean difference [95% CI] 0.00224 [0.00025, 0.00423], p = 0.0204). Conclusions: The addition of ONS + DC significantly improved linear catch-up growth outcomes in children at risk of undernutrition as a result of improved energy and nutrient intake and a higher protein-to-energy ratio.

Background: The fetal period is critical for neurodevelopment, with maternal diet emerging as a key environmental factor influencing long-term child health. This study investigated the associations between maternal dietary patterns during pregnancy and neurocognitive and behavioral outcomes in 4-year-old children, with a particular focus on sex-related differences. Methods: We used data from the Piccolipiù Italian birth cohort, including 2006 mother/child pairs. Maternal dietary intake during pregnancy was assessed via a questionnaire and categorized into distinct patterns using Principal Component Analysis (PCA). Child neurodevelopment was evaluated at age 4 using the Wechsler Preschool and Primary Scale of Intelligence (WPPSI) and the Child Behavior Checklist (CBCL 1.5–5). Linear and logistic regression models were employed, adjusting for potential confounders and stratifying by child sex. Results: Two major maternal dietary patterns were identified: “Processed and high-fat foods” and “Fresh foods and fish”. Higher maternal adherence to the “Processed and high-fat foods” pattern was associated with increased externalizing behaviors in offspring (β = 0.88; 95%CI 0.28–1.49; p = 0.004). In males, this pattern was associated with an increased clinical risk of Attention Deficit Hyperactivity Disorder (ADHD) (OR (Odds Ratio) = 1.13; 95%CI: 1.02–1.26; p = 0.021). Conclusions: Our findings indicate that maternal consumption of a diet rich in processed and high-fat foods during pregnancy is associated with increased behavioral problems in children, with sex-specific vulnerabilities: slightly higher externalizing behaviors in girls and an increased risk of ADHD in boys. These results underscore the importance of promoting healthy maternal dietary patterns during pregnancy as a targeted early prevention strategy for supporting child neurodevelopment. Full article

Breast cancer is the most common malignant tumor among women. It is a significant health and social issue affecting 2.3 million women worldwide. Breast cancer is caused by various factors, including gender, age, race, genetics, hormonal balance, obesity, alcohol and many others. A crucial issue related to breast cancer is the impact of diet on the development of the disease. Dietary fats play a key role. Saturated fatty acids and trans fatty acids increase the risk of breast cancer, while polyunsaturated fatty acids have a protective effect. A high-protein diet reduces the risk of breast cancer and improves prognosis among patients. The role of carbohydrates remains unclear, but women may benefit from reducing their intake of high glycemic index foods. Among the macronutrients influencing the development and progression of breast cancer are calcium and magnesium. Adopting a Mediterranean diet may offer benefits. Among the factors influencing the development of breast cancer, the gastrointestinal microbiota is also noteworthy. Regular physical activity can reduce the risk of developing breast cancer, support treatment, reduce side effects and improve patients’ quality of life. Chronic stress also contributes to the development of breast cancer by affecting the nervous, hormonal and immune systems, disrupting the body’s homeostasis. Full article
