Saline–alkaline aquaculture is a promising strategy to alleviate freshwater shortages; however, such environments severely impair fish growth and physiological homeostasis. Nutritional regulation has been proposed to improve stress tolerance, yet the benefits of single additives are often limited under the multifactorial challenges imposed by saline–alkaline conditions. Therefore, a compound feed additive (CFA) consisting of glutamate, cholesterol, β-glucan, myo-inositol, zinc methionine, and curcumin was developed and evaluated in Nile tilapia (Oreochromis niloticus). To assess the robustness and practical applicability of this nutritional strategy, three independent feeding trials were conducted using different commercial basal diets as validation systems. Within each dietary system, fish were reared under freshwater (FW), saline–alkaline water (SAW), or saline–alkaline water supplemented with CFA (SAW+CFA). Saline–alkaline stress significantly reduced WG and SR, increased FCR, and elevated VSI and HSI, indicating impaired growth performance and metabolic burden. These changes were accompanied by increased serum glucose and ion concentrations (Na⁺, K⁺, Cl⁻), elevated ammonia levels, and reduced crude protein content. Dietary CFA improved growth and feed utilization under saline–alkaline conditions. It enhanced hepatic glycogen content and reduced serum glucose levels. Meanwhile, it downregulated glycolysis-related genes (hk, pfk1, pk) and upregulated genes involved in gluconeogenesis and the pentose phosphate pathway (g6pase, pc, g6pdh), indicating altered glucose metabolism and improved energy homeostasis. Saline–alkaline stress induced oxidative stress, apoptosis, and histological damage in the liver, whereas CFA alleviated these alterations by reducing MDA levels, enhancing antioxidant enzyme activities (CAT, GSH-Px, T-SOD) and suppressing apoptosis-related genes (caspases, p53, c-myc). In addition, CFA alleviated saline–alkaline stress-induced gill structural damage and reduced serum ion concentrations while modulating ion transport-related gene expression, suggesting improved osmoregulatory capacity. It also enhanced ammonia metabolism and transport, as reflected by reduced serum ammonia levels and altered expression of related genes. Furthermore, Saline–alkaline stress impaired intestinal structure and function, whereas CFA improved intestinal villus structure, increased digestive enzyme activities (amylase, trypsin, lipase), and suppressed pro-inflammatory genes (il-1β, il-8). Importantly, similar beneficial response patterns were observed across the three independently analyzed dietary systems. Overall, CFA improved saline–alkaline adaptability of Nile tilapia and was associated with improvements in energy metabolism, oxidative homeostasis, osmoregulation, ammonia detoxification, and intestinal function, providing a practical nutritional strategy for saline–alkaline aquaculture.

The increasing spread of invasive alien species (IAS) represents one of the major causes of biodiversity loss, making containment practices necessary. In this regard, the circular economy framework proposes to reuse the biomass from IAS in growing sectors such as aquaculture, in which more sustainable practices are required. This study evaluated the possibility of using biomass derived from two widespread freshwater IAS, Procambarus clarkii and Silurus glanis, as dietary ingredients for Oncorhynchus mykiss. Experimental diets were formulated by incorporating 20% of IAS-derived muscle powder into a commercial feed, and their effects were assessed through a 35-day feeding trial. Chemical analyses confirmed the nutritional suitability of the formulated diets and the absence of antibiotic residues. No mortality or significant differences in growth performance were observed among treatments. Blood biochemical parameters showed limited variations, remaining within physiological ranges, while oxidative stress biomarkers indicated only minor, diet-specific responses without evidence of oxidative damage. An increase in Hsp70 expression suggested adaptive physiological responses rather than pathological stress. Histological analyses of liver and gut tissues revealed no structural alterations across experimental groups. Overall, the results demonstrate that the inclusion of IAS-derived biomass at 20% is well tolerated by O. mykiss and does not impair fish health. These findings support the potential of invasive species valorization as a sustainable strategy for aquaculture feed production, contributing to both resource efficiency and ecosystem management.

Background/Objectives: Dietary habits are important modifiable factors influencing survival among cancer patients. The dietary quality among cancer survivors may differ from those of the general population and may vary according to age at cancer diagnosis. This study aimed to compare dietary quality between cancer survivors and the general population and to examine whether age at diagnosis is associated with dietary quality. Methods: This retrospective cross-sectional study used data from 8706 adults aged ≥ 30 years (641 cancer survivors and 8065 controls) from the 2019–2021 Korea National Health and Nutrition Examination Survey. Dietary quality was assessed using the Diet Quality Index-International (DQI-I; range 0–100). Survey-weighted multiple linear regression models were used to compare DQI-I scores between cancer survivors and controls. Subgroup analyses were stratified by age at diagnosis, and quadratic age terms were included to assess nonlinear associations. All analyses accounted for the complex survey design. Results: Cancer survivors had significantly higher mean DQI-I scores than controls (69.1 ± 0.4 vs. 66.1 ± 0.2; p < 0.001). Among survivors diagnosed before age 50, dietary quality was significantly higher in those currently under 65 years than in controls (mean difference +3.02, 95% CI 1.44–4.60), but notably lower in those aged ≥ 65 years (−3.18, 95% CI −6.16 to −0.20). In contrast, survivors diagnosed at age ≥ 50 consistently showed higher dietary quality than controls across all age groups (+3.76, 95% CI 2.83–4.68). Conclusions: While cancer survivors generally exhibit better dietary quality than the general population, this positive trend was not observed among younger-onset survivors in older age groups. These findings suggest that age at cancer diagnosis may be associated with dietary quality and highlight the need for sustained, age-specific nutritional support strategies in cancer survivorship.

Yellow mealworm (Tenebrio molitor) larvae can convert low-value organic residues into insect biomass, but their performance depends on substrate composition and feeding strategy. We evaluated vegetable wastes, okara–wheat–bran diets and kitchen waste–wheat–bran mixtures under a dynamic feeding regime. Ingredient and proximate compositions were determined, and larval growth, fresh-weight-based waste reduction (WR), bioconversion rate (BCR) and feed conversion efficiency (FCE), pupal output, nutritional composition and heavy metal contents were assessed. Among vegetable wastes, potato showed the highest numerical WR (95.18 ± 0.73%) and relatively high BCR and FCE, whereas pumpkin produced the most pupae (109.00 ± 8.62 per replicate). Cabbage showed reduced biomass conversion and pupal output. In the okara trial, 40% okara showed the highest numerical WR (75.88 ± 0.39%), 10% okara maximized FCE (15.83 ± 0.38%) and 20% okara produced the greatest pupal output. Principal component analysis (PCA) indicated treatment-specific conversion and developmental patterns, but was interpreted as an exploratory association analysis rather than a causal model. Kitchen waste mixtures increased the relative fat proportion and reduced the relative protein proportion of larvae; the 3:2 mixture increased crude fat to 37.90 ± 0.22% while retaining 57.39 ± 0.40% crude protein. Higher kitchen waste inclusion was associated with greater larval arsenic (As) content, reaching 0.803 ± 0.001 mg/kg in the 5:2 treatment. Substrate composition should therefore be optimized together with conversion efficiency, product quality and safety screening. Full article

Bacillus subtilis has been widely investigated as a probiotic feed additive for weanling piglets due to its potential to improve growth performance, gut health, and disease resilience during the post-weaning period. This systematic review evaluated the effects of Bacillus subtilis supplementation in pigs following PRISMA guidelines and the PICOS framework. A total of 619 records published between 2000 and 2025 were identified through PubMed, Scopus, and AGRICOLA databases, of which 29 studies met the inclusion criteria for qualitative synthesis. Overall, Bacillus subtilis supplementation frequently improved average daily gain, body weight, feed efficiency, and reduced diarrhea incidence, particularly under enteric challenge conditions. Many studies also reported beneficial effects on intestinal morphology, immune regulation, intestinal barrier-related gene expression, nutrient digestibility, and modulation of gut microbiota toward bacterial communities associated with intestinal health. However, responses varied depending on Bacillus subtilis strain, dosage, diet composition, and experimental design. In contrast, effects on biochemical and oxidative stress indicators were less consistent across studies. Collectively, the findings support the potential role of Bacillus subtilis as a functional probiotic in swine nutrition while highlighting the need for standardized long-term studies to better define optimal strains, supplementation strategies, and mechanisms of action.

Background/Objectives: Enhanced Recovery After Surgery (ERAS) protocols improved outcomes in colorectal surgery, but global implementation remains heterogeneous. In centers without structured ERAS programs, the lack of standardized discharge criteria could lead to conservative decisions and prolonged hospital stays. This study aimed to evaluate the feasibility and safety of early discharge (ED) on postoperative day (POD) 3 using the five Tavernier’s criteria in a real-world setting without formal ERAS pathways. Methods: This retrospective analysis of a prospectively maintained database included all consecutive adult patients undergoing elective laparoscopic colorectal resection between February 2025 and February 2026 at a high-volume tertiary center. Patients were stratified into the EARLY group (discharged on POD 3 upon fulfilling all five Tavernier criteria: C-reactive protein < 150 mg/L, temperature < 38 °C, passage of flatus, Visual Analogue Scale score < 5, and oral diet tolerance) and the STANDARD group (discharged after POD 3). The primary endpoint was the safety and negative predictive value (NPV) of the five-criteria bundle regarding 30-day complications. Results: Seventy-seven patients were included (EARLY: n = 44; STANDARD: n = 33). In the STANDARD group, the primary barriers to discharge were prolonged intravenous analgesic requirements (81.8%) and delayed bowel function (36.4%). The five-criteria bundle demonstrated an NPV of 84.1%, a sensitivity of 68.2%, and a specificity of 67.3% for identifying patients at low risk of complications. The overall 30-day complication rate was significantly lower in the EARLY group compared to the STANDARD group (15.9% vs. 45.5%; p = 0.010). No major complications (Clavien–Dindo ≥ III) occurred in the EARLY group compared to 6.1% in the STANDARD group. Conclusions: This exploratory feasibility analysis suggests that early discharge on POD 3 guided by the five Tavernier criteria is potentially safe and feasible in a real-world clinical setting without formal ERAS pathways. However, given the small sample size and inherent methodological biases, these findings remain preliminary, and larger prospective multi-center trials are strictly required to validate the safety and formal impact of this strategy.

Plant-based formulations supplemented with probiotics are a promising strategy to improve nutrient bioavailability in aquaculture, yet mechanistic understanding of microbial modulation of host metabolism remains limited. We evaluated whether supplementation with Bacillus velezensis (Sp1) and B. amyloliquefaciens (Sp3) influences metabolic efficiency and energy allocation in sub-adult red abalone (Haliotis rufescens). Over 180 days, animals were fed a plant-based or a fishmeal-based diet—both probiotic-supplemented and matched in protein and energy—and compared with fresh kelp (Macrocystis pyrifera) as a control. Metabolic performance was assessed from oxygen consumption, relative specific dynamic action (SDA) index, ammonia excretion and Oxygen-to-nitrogen ratio (O:N) ratio. The Bacillus-supplemented plant-based diet achieved metabolic efficiency comparable to M. pyrifera, with minimal SDA (4.7% vs. 4.3%) and commercially viable growth (2.07 mm/month). The O:N ratio indicated diet-specific, time-dependent shifts in substrate use. The fishmeal-based diet—despite identical macronutrient and probiotic composition—produced a markedly higher postprandial metabolic cost (SDA = 21.0%), consistent with reduced compatibility between high animal protein and herbivorous digestive physiology. Overall, probiotic supplementation may help convert plant-based ingredients into metabolically efficient functional feeds, offering a more sustainable approach that reduces dependence on marine-derived ingredients.

Acne vulgaris is a common chronic inflammatory disorder of the pilosebaceous unit that is increasingly recognized as a condition linked to systemic metabolic disturbances. Growing evidence suggests that alterations in lipid metabolism, both in sebum composition and circulating lipid profiles, may play a key role in acne pathogenesis. This narrative review aims to summarize current knowledge on the relationships between lipid metabolism, body composition, diet, and acne. Acne vulgaris should be considered not only a dermatological condition but also a disorder with metabolic components. A deeper understanding of lipid-related mechanisms may support the development of more personalized and metabolically targeted therapeutic strategies. Full article

Background: Epilepsy is a complex neurological disorder in which growing evidence supports a significant role for the microbiota–gut–brain axis (MGBA) in modulating neuroinflammation, neuronal excitability, and treatment responsiveness. Beyond their traditional role in inducing ketosis, dietary therapies may influence epilepsy by modulating gut microbial ecology, intestinal barrier integrity, immune signaling, and microbiota-derived metabolites. Methods: This narrative review critically examines current clinical and experimental evidence regarding the relationship between epilepsy, gut microbiota, and dietary interventions. Particular attention was given to ketogenic dietary therapies, the Modified Atkins Diet (MAD), low-glycemic-index treatment (LGIT), Mediterranean dietary patterns, restrictive diets, and microbiota-targeted supplementation, including probiotics, prebiotics, and postbiotics. Results: Available evidence suggests that patients with epilepsy exhibit alterations in gut microbial composition associated with impaired short-chain fatty acid production, intestinal inflammation, and altered neuroimmune regulation. Ketogenic and microbiota-supportive dietary approaches may modulate these pathways beyond ketosis alone, potentially contributing to seizure reduction through integrated metabolic, inflammatory, and microbial mechanisms. Emerging evidence also supports a role for probiotics, prebiotics, and postbiotics in modulating gut–brain communication and neuroinflammatory signaling, although current clinical data remain limited. Conclusions: Dietary therapies in epilepsy should no longer be viewed exclusively as metabolic interventions aimed at inducing ketosis, but rather as potential modulators of the microbiota–gut–brain axis and neuroimmune homeostasis. While further mechanistic and clinical studies are needed, microbiota-targeted nutritional approaches may represent valuable complementary strategies to be integrated alongside conventional antiseizure therapies within more personalized models of epilepsy management.

Palm fruits are produced extensively in tropical and subtropical regions and consumed worldwide. However, over 20% of the total yield is discarded due to inferior quality, resulting in significant agricultural waste and economic loss. To mitigate this challenge and enable the safe valorization of discarded dates (DD) in animal feeding systems, this study employed solid-state fermentation (SSF) to upgrade the nutritional quality of DD and evaluated its potential as a functional feed ingredient for goats. Twenty-four male goats (6 months old; initial body weight 25.86 ± 0.25 kg) were randomly assigned to one of three dietary treatments: a basal diet (control), a diet containing 10% raw DD (D1), and a diet containing 10% solid-state fermented DD (D2). Inclusion of DD in the diet significantly increased average daily gain (ADG), final body weight (BW), and feed efficiency, with the highest values recorded for D2 (p < 0.05). Feeding of DD altered (p < 0.001) all measured rumen fermentation parameters, except pH, with higher levels (p < 0.05) of total volatile fatty acids, propionate, microbial crude protein, and ammonia nitrogen recorded for D1 and D2, as compared to control. Similarly, blood biochemistry revealed elevated total protein, albumin, and globulin in both supplemented groups (p < 0.05), whereas higher glucose and cholesterol levels were recorded for the D1 group (p < 0.05). Notably, systemic antioxidant status improved with the inclusion of SSF fermented DD, as evidenced by increased superoxide dismutase, glutathione peroxidase, and catalase activities, alongside reduced malondialdehyde levels (p < 0.05). The inclusion of DD in the diet decreased cooking and drip losses, and decreased shear force (indicating enhanced tenderness) and water-holding capacity (p < 0.05), with better values recorded for D2. Carcass protein and fat contents increased with the inclusion of DD in the diet, with higher values recorded for D2 (p < 0.05). Fatty acid analysis revealed higher (p < 0.05) contents of rumenic acid and octadecenoic acid in D2, as compared to D1 and control. The concentrations of lysine, methionine, threonine, leucine, and valine in meat were also higher in D2-fed goats (p < 0.05). In conclusion, incorporating solid-state-fermented discarded dates into goat diets represents a promising and sustainable strategy to valorize agricultural waste while concurrently improving growth performance, antioxidant status, meat quality, and selected nutrient profiles of goat meat. These preliminary findings warrant validation in larger-scale production. Full article

Spirulina, a cyanobacterium recognized for its nutritional and environmental advantages, has emerged as a potential ingredient for sustainable diets. Consumer acceptance remains limited despite its benefits, particularly due to sensory challenges and limited prior awareness. This study aimed to investigate knowledge, consumption patterns, and attitudes toward Spirulina among a Brazilian sample. A cross-sectional online questionnaire distributed via social media and public spaces yielded 933 valid responses, categorized into three groups based on prior awareness and consumption history. Results indicated limited prior awareness and low consumption, with more than half of consumers having tried Spirulina only once. Education, income, generation, and health-related behaviors were associated with knowledge and consumption, although most effect sizes were small. Knowledge of Spirulina was concentrated on nutritional attributes, whereas environmental and technological attributes were less widely recognized. Health and environmental benefits were most often rated as increasing willingness to consume Spirulina, while self-reported barriers included taste, smell, and issues related to powdered and capsule forms. Preferred applications were in familiar food categories such as baked goods and powdered mixes. These findings indicate that Spirulina occupies a niche position among respondents and suggest the relevance of sensorially acceptable formulations, tailored communication strategies, and inclusive educational efforts.

Reflectance by yellow to red carotenoid-based plumages in birds with ultraviolet-sensitive (UVS) color vision typically shifts to redder (longer) wavelengths as carotenoid consumption (Diet_c) increases. This apparent asymmetric red-shift response implies an overall bias against conceivable shifts to bluer (shorter) wavelengths. However, recent studies among species of Piciformes–Coraciiformes (e.g., woodpeckers, barbets, toucans, bee-eaters, and allies) with violet-sensitive (VS) color vision discovered two kinds of blue shifts between the same plumage and dietary traits. Compared to UVS absolute red shifts (positive slopes at higher Diet_c), VS express absolute (negative slopes at higher Diet_c for yellow and orange plumages) or relative (zero slope for red plumages) blue shifts. These contrasting patterns for different color vision systems suggest that generalized symmetry concepts of opposite (plumage shift) patterns that maintain invariant (Diet_c, perception) processes can be abstracted from physical to biological systems, with positive versus negative responses formalized as “antisymmetries” and relative responses formalized as “broken symmetries”. A subset of VS “true woodpecker” (Picinae) species with known yellow and red plumage-carotenoid chemistries demonstrated similar blue shifts for the main reflectance bands and their independence from phylogeny, sex, and specimen collection year, thus providing key chemical details to further test generalized plumage symmetries. Juxtapositions were facilitated because both yellow and red plumages in true woodpeckers contained comparatively blue- and red-shifted carotenoid types. Despite this parallel, each plumage deployed chemical variations in radically different ways. Yellow plumage contained only chemically defined yellow carotenoids, including intrinsically more red-shifted natives (i.e., hydroxy-xanthophylls) widespread among birds through their diets, and intrinsically more blue-shifted picofulvins (i.e., 7,8-di- and tetra-hydro-carotenoids) probably characteristic of and metabolized by VS birds. Higher absolute and relative (to natives) picofulvin concentrations were significant predictors of absolute blue shifts in yellow plumage reflectance, and were significantly predicted by higher Diet_c. Transitivity implied Diet_c ⟶ native ⟶ picofulvin ⟶ reflectance, such that picofulvins caused absolute blue shifts at higher Diet_c, and natives caused absolute red shifts at lower Diet_c. Moreover, opposite trends for picofulvin and native concentrations in feathers were consistent with the proposed endogenous synthesis of picofulvins from natives. Yellow plumages comprised mainly of picofulvins at very low (from very low Diet_c from ants and termites) or high (from very high Diet_c from fruits) concentrations were especially distinctive for some of these and other interrelationships, suggesting some heterogeneity in yellow pigmentation strategies from dietary idiosyncrasies. Red plumages contained only relatively low concentrations of yellow dietary natives (hydroxy-xanthophylls), but varied widely in the concentration of metabolites of comparatively intermediate (4-oxo-keto-carotenoids) or extreme (4,4′-oxo-keto-carotenoids) redness. However, different red chemistries lacked any corresponding significant relationships with variations in reflectance or Diet_c. Variations in reflectance based on chemical compositions were more visible to humans for yellow than red plumage types, setting minimum salience levels for the more discriminating diurnal avian color visions. Therefore, VS yellow plumage chemistries that emphasize deposition of easily obtained (cheaper) dietary natives at low Diet_c, and of more deliberately synthesized (costly) picofulvin metabolites at higher Diet_c were consistent with several forms of honest signaling in UVS from resource limitations based on Diet_c, including through potential costs and benefits and their trade-offs. Conversely, the diverse chemical compositions and costs of red plumages of similar physical reflectance properties, and evidence that intrinsically orange carotenoids intermediate between red and yellow ones were actively excluded from plumage, suggested that true woodpecker reds were under selection for a convergent appearance. In light of true woodpecker biology, sensory bias, and social and aposematic mimicry are likely mechanisms promoting resemblance. These results extend to the chemical level earlier interpretations of opposite shift patterns as antisymmetries of invariant processes and relative shift patterns as broken symmetries of altered processes for VS vis-à-vis UVS carotenoid-based systems.

Skeletal deterioration is a major welfare and production concern in laying hens, as substantial quantities of calcium are mobilized from bone to support eggshell formation during the laying cycle. Nutritional strategies that promote skeletal development during the pullet phase may therefore improve bone integrity later in production. The objective of this study was to evaluate the effects of dietary genistein supplementation on growth performance, bone development, and mineralization in Hy-Line Brown pullets. A total of 600 pullets were randomly assigned to four dietary treatments consisting of a control diet (0 mg/kg genistein; CON) or diets supplemented with 20 (G20), 60 (G60), or 100 mg/kg (G100) genistein from 5 to 17 weeks of age. Growth performance, bone mineral density, muscle deposition, biomechanical strength, bone ash content, and circulating bone formation biomarkers were evaluated. Pullets receiving G60 and G100 supplementation exhibited greater body weight, bone mineral density, cortical bone area, muscle weights, biomechanical strength, bone ash percentage, and circulating concentrations of BALP and P1NP compared with CON and G20 birds. Feed intake did not differ among treatments. These findings indicate that genistein supplementation, particularly at 60 and 100 mg/kg, may enhance skeletal development during the pullet rearing period. Further research is warranted to determine whether these improvements persist throughout the laying cycle and influence production, as well as the potential deposition of genistein-derived compounds in eggs.

Agronomic biofortification represents an effective strategy to counteract hidden hunger in humans. Salts and synthetic chelates are widely used as foliar or root applications for enriching vegetables with mineral nutrients. Recently, biochelates have been proposed as a sustainable alternative to synthetic chelates, especially peptide-based biochelates that combine the beneficial role of peptides as biostimulants and chelating agents. This study investigated the impact of multiple foliar applications of two peptide-based biochelates for enhancing Fe and Zn in leaves of hydroponically grown lettuce. No significant differences were observed in the fresh and dry weight of lettuce shoots, leaf pigments, leaf antioxidant activity and leaf macronutrient profile, while a significant increase in biochelate treatments was observed in leaf Fe and Zn concentrations in comparison with untreated control (+38.1% and +44.1%, respectively). Leaf concentration of Fe and Zn in biochelate treatments allowed to estimate that 100 g of biofortified fresh lettuce shoots per day in the human diet can contribute to Population Reference Intake from 7.9 to 11.5% for Fe and from 3.3 to 3.9% for Zn. Moreover, Zn-peptide treatments reduced nitrate concentration with respect to control and Fe-peptide (−9% and −11%, respectively), increasing the quality of lettuce leaves. Overall, peptide-based biochelates proved to be a promising, environmentally friendly fertilizer for lettuce biofortification, enhancing Fe and Zn concentration without impairing yield and leaf quality.

Back-ground: In 2022, in Niger, undernutrition was highly prevalent in 6–23-month-old infants and their diet was poorly diversified. Methods: This cluster randomized controlled trial was conducted in the Zinder region of Niger to monitor food and nutritional intakes from two food solutions, fortified infant flours (FIF) and ten nutritionally improved traditional recipes (NITR), in breastfed 6–11-month-old infants divided into four groups: control, responsive feeding (RF) awareness raising, RF + FIF, and RF + NITR. Data were collected at T0 (n = 322 infants) and 3 months later (T3, n = 300 infants). Results: At T0, 29% and 52% of infants had stunting and anemia, respectively, and 24% of them achieved minimum dietary diversity (MDD) in all groups. At T3, the MDD rates significantly increased, particularly in the RF + FIF and RF + NITR groups (71% and 81%, respectively). Food intake remained low in all groups, below the gastric capacity of children. Nevertheless, at T3, food intake was significantly higher in the RF + NITR group than in the other groups (p = 0.0209). Although porridges made with FIF were consumed in smaller quantities, thanks to their high energy density, the mean energy intake was higher in the RF + FIF group than in the control and RF groups. The energy intake of the RF + NITR group was even higher. This can be attributed to the fact that NITR-based meals were more varied, and colorful and offered different tastes and textures, thus appearing more appetizing and stimulating. Conclusions: A strategy that combines FIF and NITR appears relevant for improving nutritional intake in these contexts. Full article
