Although plant-based convenience foods have gained significant market share, many are high in fat, salt, and sugar while low in nutrients. The current study aimed to develop a vegan oyster mushroom soup powder enriched with moringa, mung bean, and pumpkin. These ingredients were chosen for their high nutritional value and availability. Four soup formulas, each containing varying amounts of moringa (0%, 1%, 2%, and 3%), were prepared, and a sensory evaluation, proximate analysis, and total aerobic plate count were carried out. The 1% moringa formulation showed the highest consumer acceptance. In this formula, moisture, ash, protein, fat, fiber, carbohydrate, and energy content were reported as 13.6%, 7.6%, 16.3%, 2.2%, 9.8%, 50.5%, and 287 kcal/100 g, respectively. The novel powdered soup product had higher amounts of phenolic compounds, total antioxidants, and iron compared to local, commercially available equivalents. Total aerobic plate counts remained below 10⁵ CFU/g; a common acceptability limit for dried soups, throughout the 4-month storage study under ambient conditions. Overall, the developed soup powder demonstrated superior nutritional quality and could support consumers in meeting their daily nutrient requirements. With further refinement, particularly by optimizing the drying process to better retain heat-sensitive nutrients, this product shows potential as an affordable and nutritious option to address inadequate protein intake and iron deficiency in Sri Lanka.

Type 2 diabetes mellitus (T2DM) and obesity represent a growing global public health challenge, strongly associated with excess body weight, unhealthy dietary habits, and a sedentary lifestyle. The ketogenic diet (KD), characterized by very low carbohydrate intake, moderate protein intake, and high fat consumption, induces a metabolic state known as ketosis, in which the body switches from glucose to fat as its primary energy source. KD has gained increasing interest as a strategy to improve glycemic control, reduce body weight, and improve lipid profiles in individuals with obesity and T2DM. The purpose of this narrative review is to summarize the current scientific evidence on the effects of KD on key metabolic parameters, including blood glucose levels, glycated hemoglobin (HbA1c), body weight, and body composition. The analysis is based on peer-reviewed articles retrieved from PubMed, Embase, and Scopus with particular emphasis on clinical studies that provide robust evidence on the efficacy and safety of KD in the treatment of metabolic disorders.

Bump feeding is a nutritional management strategy in swine production that involves increasing feed allowance and/or dietary nutrient density during the final weeks of gestation, usually from day 90 to farrowing, to support rapid fetal growth and prepare sows for lactation. This strategy is widely applied to improve piglet birth weight, neonatal viability, and subsequent reproductive performance. This review synthesizes current evidence on the effects of increased maternal feed intake during late gestation on sow body condition and feeding-related behavioral responses, and farrowing outcomes. Available studies suggest that increasing feed allowance during late gestation can influence litter characteristics, piglet survival at birth, and sow energy reserves, as reflected by changes in backfat thickness (BFT) and body condition score (BCS). The nutritional composition of bump-feeding diets, including dietary energy and amino acid balance, is critically evaluated in relation to pregnancy maintenance, farrowing duration, and early lactation performance. In addition, the roles of parity and feeding behavior during late gestation are examined, with particular emphasis on their associations with sow activity patterns, restlessness around parturition, and farrowing efficiency. Despite these reported effects, findings across studies remain inconsistent, particularly regarding the balance between improved reproductive outcomes and the risk of excessive fat deposition in sows. This review highlights key knowledge gaps and underscores the need for optimized, parity-specific bump-feeding strategies that integrate nutritional management with feeding behavior to enhance farrowing performance, piglet survival, sow welfare, and economic sustainability in modern pig production.

Background: Calcium (Ca) and magnesium (Mg) are essential micronutrients integral to metabolic processes and cardiovascular health. Emerging evidence suggests that the dietary Ca:Mg ratio may influence chronic disease risk, yet variability in this ratio across diverse demographic groups and its relationship to body composition and vitamin D status remain unclear. Methods: Dietary intakes of Ca and Mg were assessed using validated Food Frequency Questionnaires (FFQs) and body composition was quantified via Dual-energy X-ray Absorptiometry (DXA) scans. Relationships between dietary Ca:Mg ratios and demographics, body composition parameters (lean and fat mass), and vitamin D and parathyroid hormone (PTH) levels were examined statistically using SPSS ver. 29.0 and R ver. 4.5.1 (2025) employing Kruskal–Wallis, regression, and moderated mediation analyses. Results: We examined 155 healthy adults with a mean age of 36.6 ± 12.5 years. Only 16.8% had adequate intakes of Mg compared with 45.8% who had adequate dietary Ca intakes. Significant differences in the Ca:Mg ratio were observed across racial groups (p = 0.023) and age groups (p = 0.017). South Asian Indians exhibited the highest median Ca:Mg ratio (4.83), whereas African Americans exhibited the lowest (2.67). Interestingly, our moderated mediation analysis indicated that African Americans were the most sensitive to the impact of PTH changes on the balance of Ca:Mg (indirect effect = −0.762, 95% CI [−1.298, −0.234]), indicating that even slight shifts in their Ca:Mg balances cause significant elevation in the PTH, which, in turn, leads to lowering of their vitamin D levels. Young adults (ages 18–29) had the highest median Ca:Mg ratio (4.73). No statistically significant differences were detected based on Gender (p = 0.425 and BMI (p = 0.744) on Ca:Mg ratios. Additionally, dietary Ca:Mg ratios were positively associated with sPTH in males (r = 0.203, p < 0.05), but not with body composition. Conclusion: Important variations in dietary Ca:Mg ratios exist across racial and age demographics, notably among young adults, and specific ethnic groups exhibited elevated ratios. Tailored nutritional interventions may be necessary for these populations to optimize Ca:Mg balance and support metabolic and cardiovascular health outcomes in these populations. Full article

Dietary fiber and phenolic compounds are key bioactives in gastrointestinal and metabolic health; however, their compositional features and metabolic implications have rarely been studied as an integrated system within realistic food matrices. Mango bagasse confectionery previously demonstrated prebiotic potential, and its reformulation with extruded mango peel showed hepatoprotective effects linked to gut microbiota modulation. In this study, mango bagasse and peel confectionery (MBPC) was characterized and its metabolic impact was evaluated in vivo. Wistar rats were fed standard or high-fat diets with or without MBPC supplementation, followed by fecal fatty acid analysis. MBPC exhibited a high dietary fiber content for a confectionery product (25 g total fiber per 100 g), with monomeric profiles indicative of cell wall-derived polysaccharides and pectic components. The fiber fraction showed a low Mw (14.71 ± 0.02 kDa), suggesting a matrix favorable for fiber–phenolic interactions. Phenolic profiling revealed substantial concentrations of free (9.0 mg/mL) and bound (16.7 mg/mL) phenolic compounds. Fecal fatty acid profiles were diet-dependent, with palmitic acid showing the highest relative abundance, followed by stearic, oleic, and linoleic acids, associated with dietary fiber intake. This study elucidates the structural and metabolic relevance of dietary fiber–phenolic interactions within a formulated food matrix. Full article

Background: Caffeine, dairy products and other food items may influence retinal microcirculation. Retinal microvascular indices provide quantitative biomarkers of systemic microvascular health and are increasingly used in clinical and research settings. The aim of this study was to elucidate the possible effects of these food products on structural and functional indices of the retinal microcirculation. Methods: Based on a registered protocol, we identified eligible interventional/observational studies examining the association of these factors with retinal biomarkers, including central retinal artery equivalent (CRAE), central retinal vein equivalent (CRVE), arteriolar-to-venular diameter ratio (AVR), retinal vascular tortuosity, vessel diameter index (VDI) and retinal vessel flicker light-induced dilation (FID). Results: Fourteen studies were included addressing caffeine (4), dairy products (2) and other food (9) consumption. Acutely, caffeine intake was dose-dependently associated with narrowed CRAE, CRVE, decreased VDI and increased AVR and FID. Long-term, caffeine consumption was associated with larger CRVE and lower AVR, while decaffeinated coffee with larger CRAE and AVR and narrower CRVE. Low-fat dairy products, fish and fiber were associated with larger CRAE, smaller CRVE, and increased AVR, while red meat consumption was associated with narrower CRAE and lower AVR. Increased salt intake was associated with increased venular tortuosity, while almond consumption was associated with larger CRVE. Owing to substantial study heterogeneity, a meta-analysis was not feasible. Conclusions: Potentially clinically meaningful associations between food groups and retinal indices were identified. These associations should be considered when evaluating retinal microcirculation and assessing CVD risk since modification of these factors may be beneficial for the cardiovascular system.

Donkey meat is valued for its high protein, unsaturated fats, and low cholesterol. Fatty acid (FA) composition critically influences meat quality and is modulated by dietary energy levels. Twenty-four meat donkeys (male) were randomly divided into three groups: a low-energy group (LEG), a medium-energy group (MEG), and a high-energy group (HEG). The trial lasted for 135 days, with dietary digestible energy levels adjusted during the pre-fattening, mid-fattening, and late-fattening phases according to the experimental design. The results showed that MEG and HEG interventions significantly upregulated tissue polyunsaturated fatty acid (PUFA) and n-3 PUFA content while reducing n-6/n-3 ratios, concomitant with enhanced activity and gene expression of most lipid-metabolizing enzymes. Notably, MEG further elevated antioxidant enzyme activities and anti-inflammatory mediators while suppressing pro-inflammatory factors. MEG and HEG significantly upregulated serum cholestane-3,7,12,25-tetrol-3-glucuronide and cortisol, along with hepatic choline, lysoPC(20:2(11Z,14Z)), glycocholic acid, and cholestane-3,7,12,25-tetrol-3-glucuronide. These modified metabolites were predominantly enriched in key metabolic pathways: pentose and glucuronate interconversions, primary bile acid biosynthesis, steroid hormone biosynthesis, glycerophospholipid metabolism, purine metabolism, and glutathione metabolism. Additionally, compared to HEG, MEG improved the antioxidant activities and immune signaling molecule levels with elevated pyroglutamic acid, glutathione, choline, inosine, adenine, and uric acid. Thus, moderately elevated dietary energy levels may enhance FA profiles in muscular and adipose tissues through coordinated regulation of lipid-metabolizing enzymes and associated gene expression, with serum and hepatic metabolites actively participating in these regulatory pathways. However, excessive energy intake could induce oxidative stress in donkeys. Full article

Background/Objectives: Hypertension control remains a global challenge. Evidence on the association between adherence to the Dietary Approaches to Stop Hypertension (DASH) diet and blood pressure (BP) control in older Mediterranean populations is limited. We aimed to assess this association in Spanish older adults. Methods: This cross-sectional analysis included 371 participants (69 ± 9 years). Dietary intake was assessed using a validated 146-item food frequency questionnaire (FFQ), and DASH diet adherence was categorized as low, medium, or high. Multivariable logistic regression models were used to examine associations with BP control. Results: Among participants with hypertension (n = 218), 52.8% achieved adequate BP control and consumed significantly more low-fat dairy products (+56%) and less sodium (−11%) than those with uncontrolled BP. The low adherence group had lower proportion of participants with controlled BP (21%) than the medium and high adherence groups (36% and 39%, respectively) (p < 0.05). Across increasing DASH diet adherence categories, systolic blood pressure (SBP) and diastolic blood pressure (DBP) were 4–5 mmHg and 3–4 mmHg lower, respectively. Medium adherence to the DASH diet was independently associated with substantially lower odds of uncontrolled BP (OR = 0.37; 95% CI: 0.16–0.82; p = 0.015). High adherence showed a similar magnitude of association but did not reach statistical significance. Conclusions: In this cohort of older Spanish adults, moderate adherence to the DASH diet was associated with meaningful improvements in BP control, suggesting that achievable, intermediate levels of DASH diet adherence may be sufficient to improve hypertension management in real-world settings. Longitudinal studies are needed to confirm causality and long-term cardiovascular benefits. Full article

Background: Acetic acid has been suggested to have health benefits. Our previous exploratory study linked acetic acid intake to higher protein and vitamin consumption, but relationships with age and sex remained unclear. Objective: This study examined associations between acetic acid intake, age, and sex, and explored nutrient correlates after adjusting for age, sex, and energy intake. Methods: Dietary data from 12,074 Japanese adults aged 20–69 years, collected via the Asken food-tracking app, were analyzed. Two-way ANOVA assessed effects of age, sex, and their interaction on acetic acid intake. Multiple linear regressions examined associations between acetic acid intake and nutrient intakes. Model 1 adjusted for age and sex; Model 2 additionally adjusted for total energy intake. Results: Participants included 3038 men (47.8 ± 11.9 y) and 9036 women (42.4 ± 11.8 y). Acetic acid intake was higher among men and older participants (sex: F = 11.0, p < 0.001; age: F = 9.1, p < 0.001). In Model 1, acetic acid intake correlated positively with most nutrients. After adjusting for energy (Model 2), negative associations were found with carbohydrates, sugars, starches, saturated fat, and butyric acid (all p < 0.05). Conclusions: Individuals with higher acetic acid intake tended to consume fewer carbohydrates and saturated fats, even at equivalent energy intake. These findings suggest that acetic acid-containing diets may reduce the intake of starches and saturated fatty acids, potentially contributing to obesity prevention. Full article

Over 10% of US children and adolescents have attention-deficit hyperactivity disorder (ADHD), with a similar prevalence among youth athletes. While ADHD may confer certain athletic performance advantages such as heightened quickness, decision-making and periods of hyperfocus, it also poses some challenges including reduced concentration, frustration, and possible increased injury risk. Pharmacologic treatments, including stimulant-based medications, can improve attentiveness and athletic performance but could alter nutritional behaviors such as appetite suppression. This paper reviews the current literature on nutritional strategies to provide practical sports nutrition guidelines for children and adolescent athletes with ADHD. Evidence suggests that optimizing energy intake, emphasizing complex carbohydrates, improving fat quality intake, and consuming adequate amounts of micronutrients may support both athletic performance and ADHD symptom management. In contrast, excessive added sugars and saturated fats are associated with poorer outcomes and manifestation of ADHD symptoms. Although no research examining nutritional interventions in youth athletes with ADHD have been performed, applying established sports nutrition principles for youth athletes with ADHD offers a promising approach to enhance performance, reduce injury risk, and support the long-term health of the athlete.

Ganoderma lucidum triterpenoids (GLTs) exhibit potential anti-obesity activity. However, their mechanism remains unclear. In this study, triterpenoids were extracted from G. lucidum via ultrahigh-pressure extraction. Using a high-fat diet (HFD)-induced mouse model, we showed that GLT treatment (100 and 200 mg/kg) significantly reduced body weight and lipid accumulation without changing food intake. Next, we found that GLT significantly inhibited preadipocyte differentiation and adipogenesis and reduced the expression of adipogenic genes, including PPARγ, C/EBPα, FASN, and SCD-1. Moreover, network pharmacology predicted a total of 306 potential targets, among which FYN, PRKCQ, PTPRF, HRH1, and HCRTR2 were identified as the core targets via a machine learning algorithm. Interestingly, GLT upregulated the expression of PRKCQ, while the deletion of PRKCQ significantly reversed the anti-adipogenic effect of GLT. In addition, we found that neutral GLT may play a dominant role in inhibiting adipogenic differentiation. These findings suggest for the first time that GLT inhibits adipogenesis and lipid accumulation via the induction of PRKCQ in adipocytes. This study provides a scientific basis for the application of GLT in the prevention and treatment of obesity, as both a pharmaceutical agent and a functional food. Full article

Parental perceptions of healthy eating often diverge from children’s actual diets, but this gap is poorly documented in Central Asia. We examined how parents’ priorities for key food groups relate to nutrient intakes in 390 urban children aged 1–6 years in Central Kazakhstan. In a cross-sectional study, parents completed a 24 h multiple-pass dietary recall and rated the importance of fats and sweets, meat and fish, dairy, vegetables and fruits, and bread and potatoes on 5-point scales. Nutrient intakes were calculated using software, compared with national DRIs, and analyzed using rank-based tests and Spearman correlations. Parents reported near-ceiling priority for restricting fats and sweets and consistently high priority for bread and potatoes, whereas vegetables, fruits, meat/fish, and dairy were rated moderately important, with dairy under-prioritized in 1–2-year-olds. On the recalled day, median intakes of fat, dietary fiber, vitamin C, and calcium were below national recommendations at all ages, and median intakes of iron, thiamine, and niacin were particularly low at 3–4 years, while sodium intake exceeded recommended levels; the 3–4-year group showed the most pronounced clustering of shortfalls. Prevalence estimates indicated that most children had intakes below recommendations for dietary fiber and calcium and above recommendations for sodium, underscoring population-wide nutritional imbalance. Across all scales, parental priorities showed only weak, non-significant associations with nutrient intakes (|r| < 0.11). These findings indicate a perception–intake gap and support interventions that ensure adequate fats, fiber, vitamin C, calcium, and bioavailable iron in preschool diets. Full article

This study evaluated the effects of dietary linseed cake on the fatty acid profile of meat and abdominal fat, and on growth performance in broiler chickens. A total of 198 birds were randomly allocated to three groups (66 birds/group). The control group (C) received a standard soybean meal-based feed, while the LIN6 and LIN12 groups were fed diets that were supplemented with 6% and 12% linseed cake, respectively. Linseed cake supplementation reduced saturated and monounsaturated fatty acids, increased n-3 polyunsaturated fatty acids (PUFAs) in meat and abdominal fat, and lowered the n-6/n-3 PUFA ratio (FDR-adjusted p < 0.05). The 12% inclusion resulted in a more pronounced accumulation of n-3 PUFAs—4.3–5.0 times higher than the control—while 6% inclusion increased n-3 PUFAs by 2.8–3.3 times (FDR-adjusted p < 0.05). However, 12% inclusion negatively affected growth performance, reducing body weight by 9.9% and feed intake by 10.4% at 42 days (p < 0.05), whereas the 6% inclusion had no adverse impact (p < 0.05). These results indicate that 6% linseed cake represents the optimal practical inclusion level, effectively enhancing the n-3 PUFA profile of broiler meat and abdominal fat without compromising growth, while higher inclusion levels may impair production performance.

The consumption of ultra-processed foods (UPFs) in adolescence is high due to their widespread availability and accessibility and has been linked to increased cardiometabolic risk. In the Autonomous City of Melilla, an environment with particular cultural and religious characteristics, it is relevant to analyze the relationship of UPFs with metabolic markers of type 2 diabetes mellitus. This is a cross-sectional pilot study on 31 Muslim adolescents aged 15 to 17 years. The NOVA food classification was used to identify UPFs. The final sample comprised Muslim adolescents because written consent for venous blood sampling was obtained only from Muslim families/legal guardians. Separate multiple linear regression models adjusted for sex were fitted to examine the associations between UPF intake (%E/day) and each cardiometabolic and inflammatory marker. Higher UPF intake was positively associated with BMI, body fat percentage, waist circumference, waist-to-height indicator (ICA), and fasting glucose after controlling for the false discovery rate (q < 0.05). Regarding the inflammatory component, Muslim girls had elevated levels of IL-7, IL-10, and IL-13, and Muslim boys had higher levels of MIP-1β. In addition, IL-8 correlated positively with waist circumference, BMI, and the HDL/LDL ratio, while MCP-1 was negatively associated with Apo A1, total cholesterol, and HDL. In this exploratory pilot study, higher intake of UPF appears to be associated with greater central adiposity and higher fasting glucose; these hypothesis-generating findings warrant confirmation in larger, representative samples and may inform culturally adapted nutritional screening in Melilla.

Long-term excessive fat intake can easily induce metabolic diseases such as fatty liver and hyperlipidemia. As a natural active ingredient, polysaccharides exhibit notable lipid-lowering effects and can serve as effective lipid regulators. Nevertheless, the lipid-lowering effect of Arabica coffee cherry peel polysaccharides (CCPPs) and the underlying regulatory mechanism remain poorly understood. This study isolated polysaccharides from coffee cherry peel, and their functional properties and the lipid-lowering effects and mechanisms on hyperlipidemic mice. In high-fat diet-fed (HFD-fed) mice, CCPP administration had significant regulatory effects on various metabolic parameters. In laboratory mice where hyperlipidemia is induced by a high-fat diet, CCPP administration improved serum lipid levels and demonstrated anti-inflammatory and antioxidant effects. These benefits were achieved by reducing pro-inflammatory cytokine expression, enhancing antioxidant enzyme activity, and lowering overall oxidative stress. Additionally, it effectively decreased fat area in liver tissues and adipocytes. Specifically, compared with the control group, after high-dose CCPP intervention, the adipocyte area of mice on a high-fat diet was significantly reduced by 41.3%. Notably, CCPP intervention resulted in a shift in the gut microbiota composition. At the phylum level, the model group showed a significant increase in Bacillota and a concomitant reduction in Bacteroidetes in comparison with the control group. Compared with the model group, CCPP intervention, especially in the CCPP-H group, resulted in an increase in the proportion of Bacteroidetes and a decrease in Bacillota. At the genus level, CCPP modulated the abundances of key bacterial genera; for instance, the relative abundance of Lachnospiraceae_NK4A136_group increased from 2.64% in the model group to 11.9% in CCPP-H group, while Faecalibaculum decreased from 62.69% to 41.27% in CCPP-L group and 25.29% in CCPP-H group. These shifts suggest that CCPP has a reparative effect on the gut microbial composition, potentially contributing to the promotion of gut health. Taken together, these factors highlight the promise of CCPP as a functional food ingredient for dietary interventions to ameliorate obesity and hyperlipidemia. Full article
