Objectives: This cross-sectional study assessed the nutritional knowledge of Saudi mothers and their children. Then, it examined the association between the nutritional knowledge of mothers and the nutritional knowledge and weight status of their schoolchildren in Makkah City, Saudi Arabia. Methods: The mothers’ nutritional knowledge was assessed using the validated Arabic version of the General Nutrition Knowledge Questionnaire (GNKQ). The children’s nutritional knowledge was assessed through an interviewer-administered questionnaire, and their weight status was determined based on their Body Mass Index (BMI) Z-score, which was calculated according to their anthropometric measurements. Results: One hundred children and sixty mothers were included in this study. Only 6.67% of the mothers had a high level of nutrition knowledge. A total of 54% of their children had low nutritional knowledge scores, and approximately 27% was classified as having excess weight. More than 40% of the children reported consuming fruits and vegetables 4–5 times/week, whereas 50% of the children consumed fast foods 1–3 times/week. Multiple linear regression analyses showed that higher nutritional knowledge scores among the children were significantly associated with higher mothers’ knowledge scores [(0.06 (95%CI: 0.0.03, 0.0.08)] and older age among these children [0.61 (95%CI: 0.44, 0.77)], as the older children had higher knowledge scores. The children’s nutritional knowledge, however, was not associated with the child’s sex, mothers’ age, or mothers’ education. The maternal knowledge scores were not associated with the child’s weight status. Conclusions: Given that the nutrition knowledge scores of Saudi mothers are significantly associated with those of their children, but not with their weight status, it can be concluded that nutrition knowledge alone may not be sufficient to address the overweight and obesity epidemic in Saudi Arabia. However, it remains a crucial component of multifaceted interventions that also enhance physical activity and promote behavior change to improve health outcomes and weight status in the Saudi population.

Neurodegenerative diseases are associated with the senescence of functional neurons, which hampers brain functions. These diseases are caused by the accumulation of reactive oxygen species, reactive nitrogen species, cholinesterase malfunction, neuronal inflammation, and mitochondrial dysfunction. The incidence of neurodegenerative disease has been on the rise. Current therapeutic interventions are expensive, exhibit poor efficacy, and have numerous side effects. Several studies have explored the potential of crucial dietary substances rich in antioxidants and micronutrients in alleviating the clinical manifestations of such deadly diseases. Consumption of sufficient antioxidants, fatty acids, and polyphenols in regular diets delays the onset of neurodegenerative diseases. Several medicinal plants, such as Withania somnifera, Curcuma longa, Panax ginseng, Ginkgo biloba, aloe vera, Punica granatum, and various phytoextracts, contain such micronutrients in reasonable amounts. Specific dietary interventions, supplements, and patterns such as the Mediterranean-DASH intervention for neurodegenerative delay, ketogenic, paleolithic, and Wahls elimination diets have been beneficial in neurodegenerative conditions. These diet interventions and other functional foods can be an attractive, non-invasive, and inexpensive approach in the management and prevention of neurodegenerative conditions. This review discusses potential pharmacological bases involved in neurodegeneration, covering mitochondrial damage, impaired mitophagy, neuroinflammation, ferroptosis, glymphatic clearance dysfunction, brain–body interactions, and disruption of vagus nerve stimulation. The review further highlights clinical diet interventions and assorted functional foods, including fruits, vegetables, vitamins, specific supplements, and special diets, for neurodegenerative conditions. The discussion extends insights into clinical research and trials of these functional foods under neurodegenerative conditions. Overall, dietary interventions show promise in the prevention and management of neurodegenerative conditions. Full article

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

This cross-sectional study assessed the prevalence of food insecurity and food literacy and examined food intake among low-income Saudi families. It provides valuable insights into the association between food literacy, food insecurity, and food intake, contributing to a better understanding of the food-related challenges faced by vulnerable families. Conducted in June 2024, this study involved 483 low-income adults in Jeddah, Saudi Arabia. Data were collected through an online questionnaire distributed via charitable organizations. Overall, 35% of the participants experienced severe food insecurity, while 91.5% demonstrated adequate food literacy. No significant association was found between food literacy and food insecurity levels (p = 0.586). However, severe levels of food insecurity were significantly associated with reduced intake of fruits, vegetables, dairy products, meat, bread and cereals, sugar-sweetened beverages, potato crisps or salty snacks, sweets, and fast food (p < 0.001). Additionally, a significant difference was observed in the consumption of potato crisps or salty snacks, with individuals exhibiting adequate food literacy consuming slightly more than those with poor food literacy (0.25 ± 0.28 vs. 0.21 ± 0.30, p = 0.04). These findings highlight the need for interventions that not only build food knowledge but also address affordability, access, and cultural food norms among low-income Saudi families. Full article

Plant-based beverages are a viable alternative for elderly consumers because of their practicality and sustainable appeal. The use of Brazil nuts for these beverages is relevant because of the added value given to the country’s agrobiodiversity and the nuts’ nutritional quality, including their high selenium content. This study aimed for the understanding and acceptance by elderly people of a vegetable beverage made from Brazil nuts and fruit. The investigation was divided into two parts: (1) development and sensory analysis of Brazil nut beverages, and (2) consumers’ perception, choice, and influencing factors for these beverages. In the first stage, four beverages were formulated with different fruit pulps. A total of 100 elderly individuals (>60 years; 69% female) evaluated the sensory acceptance and purchase intention of the beverages. In the second stage, an online questionnaire was applied to 220 elderly individuals (>60 years-old; 52.7% female), which consisted of a choice test of nut beverage packages, a food neophobia scale, and questions about vegetable beverage consumption. The study showed that the selenium claim was one of the most relevant factors in the choice, demonstrating that using Brazil nuts can boost beverage purchases. Further tests are still needed to improve the attributes, such as sweet taste and appearance. Despite this, the blend of Brazil nuts with fruits positively influenced the choice and acceptance of these products by elderly individuals. 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

Background/Objectives: To prevent nutritional depletion and impaired weight status in infants, targeted public health policies and prevention programs based on scientific evidence are needed. This study provides an overview of the dietary patterns and feeding behavior of infants in Croatia as part of the National Food Consumption Survey on Infants and Children. Methods: This cross-sectional study was conducted following the EU Menu methodology and included 322 healthy infants (54% boys; aged 3 months up to 12 months) from Croatia. Two-day dietary records were collected and analyzed using NutriCro 2.0 software. Results: The daily energy intake of infants was on average 886 ± 219 kcal, mainly from carbohydrates (47.0%), followed by fat (41.6%) and protein (9.9%). The main sources of energy and macronutrients were milk and dairy products, grains, grain products, potatoes and tubers and the fruit food group. One third of infants were breastfed, and more than 70% of infants were introduced to complementary foods. Parents started complementary feeding at the age of 5.37 ± 0.82 months, mostly with vegetables. Breastfeeding was associated with higher energy intake, especially in infants younger than 6 months, while formula feeding was associated with lower energy intake. The multivariate regression models showed age-related interactions that attenuated the patterns for energy and macronutrient intake. Conclusions: The study emphasizes that milk and dairy products are the main source of energy and macronutrients. The study highlights the important role of breastfeeding in promoting higher energy intake in early infancy and the decreasing effect of infant formula consumption with age. These results can be used as a basis for health policies, programs and strategies that address infant feeding habits in Croatia. Full article

Understanding food production (FP) supply–demand relationships is crucial for achieving Sustainable Development Goal 2 (SDG 2). Previous studies often assessed these relationships by overlaying supply and demand without considering food production flow (FPF). This study developed a framework from the perspectives of supply, demand, and flow to analyze the Agrifood System (AFS) of four major urban agglomerations in China: Beijing–Tianjin–Hebei, the Yangtze River Delta, the Pearl River Delta, and Chengdu–Chongqing. It applied the enhanced two-step floating catchment area model to simulate the magnitude and direction of four types of FPF—grains, vegetables, fruits, and meat—under three scenarios: intra-city flow, intra-provincial flow, and free flow. Results revealed mismatches in the FP supply–demand, and incorporating FPF improved these relationships. As flow restrictions eased, intra-city flows decreased, cross-regional flows expanded, and supply–demand imbalances were alleviated. Enhancing regional cooperation plays a key role in addressing the spatial mismatch between food supply and demand. These findings provide useful insights for addressing food supply–demand mismatches through more proper agricultural land allocation, better alignment of consumption patterns, and improvements in the flow system.

Background/Objectives: Children with neurodevelopmental disorders (NDDs) frequently present with feeding challenges that can lead to inadequate fruit and vegetable consumption, which can increase their risk of nutritional deficiencies and related health issues. The aim of this scoping review was to describe the main interventions focused on promoting fruit and vegetable consumption in children with NDDs. Methods: Two authors carried out a search strategy in PubMed, Scopus, EMBASE, Web of Science, and PsycINFO using the following terms: “autism OR autistic OR asperger OR rett OR pervasive OR disintegrative OR ‘neurodevelopmental disorder’ OR ‘attention deficit disorder with hyperactivity’”; and the outcome (O): “fruit OR vegetable”. We included all randomized or non-randomized studies, published in English or Spanish, which assessed children’s fruit and vegetable consumption. Results: We included seven articles that applied different interventions, such as a mobile health and behavioral modification program (n = 1), repeated food exposure programs (n = 2), a play-based program with parental training (n = 1); the implementation of Dietary Approaches to Stop Hypertension diet (n = 1); an intensive interdisciplinary mealtime behavioral treatment (n = 1); and restrictive diets (n = 1). Conclusions: Parent-led behavior changes supported by multidisciplinary teams using play, positive reinforcement, and food modification strategies were the main interventions used to increase fruit and vegetable consumption in children with NDDs. This review supports designing evidence-based approaches to improve feeding challenges in this population. Full article

Background: Parenting styles are associated with various health outcomes among children, such as fruit and vegetable consumption, physical activity, and emotional well-being. Previous literature suggests that responsive parenting styles are associated with improved mental health outcomes. This study examines the association between an adult’s responsive parenting style and the psychosocial outcomes of emotion regulation and loneliness among children. Methods: Using data from the U.S. National Cancer Institute’s Family Life, Activity, Sun, Health, and Eating (FLASHE) cross-sectional survey, this secondary data analysis study seeks to understand how perceived parental responsiveness is associated with adolescents’ emotional health outcomes from the perspective of the adolescent. The sample consisted of 12- to 17-year-olds (n = ~1560), mostly female (50.2%) and non-Hispanic White (63.7%), with a mean age of 14.48 years (SD = 1.61). Results: Through multivariable regression, we found that perceived parental responsiveness negatively predicted adolescent emotion suppression (β = −0.29, p < 0.001), even after controlling for sex, age, race/ethnicity, parental marital status, parental education level, parent’s time spent at work, and the number of kids in the household (β = −0.29, p < 0.001). We also found that perceived parental responsiveness was the strongest predictor for adolescent loneliness (β = −0.27, p < 0.001), even when controlling for sex, age, race/ethnicity, parental marital status, parental education level, parent’s time spent at work, and the number of kids in the household (β = −0.28, p < 0.001). Conclusions: These results suggest that implementing interventions targeting parental responsiveness may be beneficial to improving adolescents’ emotional well-being. Full article

Background/Objectives: Recent data shows increasing diabetes prevalence among African Americans. Youth with a family history of diabetes are at high risk for diabetes. This study explores the multilevel risk factors associated with a family history of diabetes among African American youth in public housing. Methods: This study used a cross-sectional, quantitative, and community-based participatory research (CBPR) approach. The research team, comprising community stakeholders and academic researchers, employed respondent-driven sampling (RDS) for data collection (survey) and used univariate and bivariate analyses to examine variable relationships. A sequential logistic regression highlighted factors influencing the likelihood of having a family history of diabetes. Results: The final sample (n = 190, mean age 18.5 years, 58% female) included 35% of youth with a family history of diabetes. Forty-six percent reported medium to severe household hardships. Results suggest that reporting a family history of diabetes is correlated with maternal substance use (tau-b = 0.27 **) and alcohol problems (tau-b = 0.16 ***), paternal substance use (tau-b = 0.17 *), and eating fewer fruits (tau-b = 0.17 *). With an odds ratio (OR) of 1.70 [0.68, 4.13] and attributable fraction among the exposed at 41.3%, the final model (3) was not significant [χ² = 11.19(8)]. Thus, we fail to reject the null hypothesis that the model fits the data well. Fewer vegetable consumption (OR = 15.08, p < 0.001), higher soda consumption (OR = 0.06, p < 0.001), severe household hardships (OR = 5.82, p < 0.01), and maternal substance use problems (OR = 6.81, p < 0.05) predicted a higher likelihood of a history of diabetes. Conclusions: Our study calls attention to the need to reevaluate interventions for hardships and substance use in diabetes management, particularly in poor neighborhoods and among minority families.

Background/Objectives: Fetal exposure to essential metals, such as iron (Fe), zinc (Zn), copper (Cu), and manganese (Mn), is influenced by maternal nutrition and lifestyle during pregnancy, potentially impacting newborn health. This study aimed to quantify concentrations of these metals in meconium and evaluate their associations, together with newborn length and weight, in relation to maternal dietary and lifestyle factors. Methods: This cross-sectional study included 152 mother–infant pairs recruited from various regions of Split-Dalmatia County, Croatia. Meconium samples were collected within 24 h after birth and analyzed for Fe, Zn, Cu, and Mn concentrations. Maternal characteristics, dietary intake, supplement use, and lifestyle factors were collected via structured questionnaires and supplemented by hospital records. Associations among maternal factors, meconium metal concentrations, and newborn birth weight and length were assessed using non-parametric statistical methods. Results: Meconium concentrations of Fe, Zn, Cu, and Mn showed substantial interindividual variability, with a strong positive correlation between Fe and Cu. Higher maternal pre-pregnancy BMI was linked to lower meconium Fe, while BMI at delivery was associated with Zn. Dietary patterns influenced metal levels: higher fruit intake was linked to increased Cu, greater vegetable intake with lower Fe, and moderate tea consumption with higher Zn. No significant associations were found with maternal smoking, residence, or supplement use. Maternal meat consumption and higher pre-pregnancy BMI were both associated with higher newborn birth weight and length. Conclusions: Maternal BMI and specific dietary patterns during pregnancy significantly influence essential metal concentrations in newborn meconium and are associated with newborn size, highlighting the importance of balanced maternal nutrition and healthy metabolic status during pregnancy.

Background/Objectives: Individuals with posttraumatic stress disorder (PTSD) tend to show patterns of elevated cardiovascular disease (CVD) risk earlier in life than the general population. The need for effective interventions for CVD risk-reduction in PTSD is increasingly evident. In this paper we present preliminary results from a longitudinal study of a health behavior intervention, as an adjunct to standard trauma therapy in PTSD. The health behavior intervention addresses CVD-related heath behaviors (physical activity, nutrition, sleep, and stress) in a 12-week program delivered individually in 90-min sessions. Behavior change recommendations included: increased aerobic activity; establishing a balanced diet, enhancing consumption of fruits and vegetables and reducing sugars and fat/saturated fat; incorporating strategies to enhance sleep and lower PTSD-related disruptions (e.g., nightmares); and relaxation and cognitive coping skills to reduce general stress. Methods: Participants were randomized to the health behavior intervention plus standard trauma therapy experimental condition or a standard trauma therapy control group. Outcomes were measured at baseline and after the 12-week intervention phase. Sleep efficiency was measured from actigraphy watches. Physical activity was assessed by self-report and blood pressure was measured using an automated device. The preliminary outcomes are for 29 participants to date who have pre-post data. Results: Sleep efficiency was improved in the intervention group compared to controls (p < 0.05). The intervention group also evidenced significant pre-post increases in moderate physical activity compared to the control group (p < 0.05). Changes in vigorous physical activity did not reach statistical significance in this preliminary sample but the pattern of results are similar to those for moderate activity. Trends toward significance were also observed for pre-post changes in systolic (p = 0.06) and diastolic blood pressure (p = 0.07), with small reductions for the intervention group and increases for the control group. Conclusions: These findings provide preliminary information about the effectiveness of the health behavior intervention on multiple parameters for adults with PTSD. The findings suggest that focusing on health behavior change in multidisciplinary treatments for PTSD may enhance outcomes such as sleep and physical activity and potentially result in greater quality of life. However, the small preliminary sample size reported here should be considered when interpreting the outcomes. Further research may also determine how improvements in health parameters impact other indices of long-term cardiovascular health. Full article

Background: The Mediterranean diet is widely recognised for its health benefits and remains a key reference point in shaping dietary guidelines across populations. Despite its growing international relevance, there is a lack of validated tools assessing Mediterranean diet adherence among children and adolescents in Central and Eastern Europe. Methods: The present study aimed to adapt and validate the KIDMED 2.0 questionnaire for use in Polish children and adolescents aged 10 to 18 years (KIDMED 2.0 PL). The adaptation process involved forward–backward translation, expert consultations, and pilot testing to ensure linguistic and cultural relevance. A total of 102 participants completed the questionnaire twice over a two-week interval, and anthropometric data were collected. Results: The KIDMED 2.0 PL demonstrated high test–retest reliability (Spearman’s ρ = 0.876; p < 0.001) and strong criterion validity, with a significant negative correlation between KIDMED scores and BMI centile (ρ = −0.854; p < 0.001). Children with normal weight showed the highest adherence to the Mediterranean diet, while scores were significantly lower in overweight and obese participants. Item-level analysis indicated that fruit and vegetable consumption was relatively frequent, whereas intake of legumes, whole grains, and extra virgin olive oil remained low. Conclusions: The KIDMED 2.0 PL is a valid and reliable tool for evaluating diet quality and Mediterranean dietary adherence in the Polish pediatric population. Full article

Background: Childhood metabolic syndrome (MetS) represents a growing public health concern in China, with diet emerging as a critical modifiable risk factor. Although numerous studies have explored the relationship between dietary patterns and MetS, the specific influence of dietary patterns associated with serum uric acid (SUA) levels in the young population remains poorly understood. The purpose of this study is to investigate the relationship between an SUA-related dietary pattern and MetS risk among children aged 9–17 years in Guangzhou, China. Methods: A cross-sectional study was conducted in Guangzhou from March 2023 to May 2024, including 4181 participants. To identify the dietary pattern associated with SUA, we employed reduced-rank regression (RRR) using 15 predefined food groups. The multivariate logistic regression models were applied to evaluate the association between the SUA-related dietary pattern scores (as continuous variables and tertiles) and the risk of MetS and its five components. Results: The SUA-related dietary pattern was characterized by high consumption of meat & meat products and beverages, and low consumption of fresh vegetables, fresh fruits & their products, eggs, dairy products, and sugary food. After adjusting for confounding factors, each one-unit increase in the SUA-related dietary pattern score corresponded to 27% higher odds of MetS (OR = 1.27, 95% CI: 1.00–1.62), and 24% higher odds of central obesity (OR = 1.24, 95% CI: 1.11–1.38). In subgroup analyses, higher adherence to the SUA-related dietary pattern scores was linked to significantly increased odds of MetS (adjusted OR = 1.69, 95% CI: 1.18–2.42) and central obesity (adjusted OR = 1.39, 95% CI: 1.20–1.62) among participants with insufficient physical activity. Conclusions: Higher adherence to the SUA-related dietary pattern was associated with higher odds of MetS in Chinese children, particularly among those with insufficient physical activity. The results provide new insights into the relationship between dietary patterns and childhood MetS, offering dietary strategies focused on managing SUA levels to prevent MetS. Full article
