Background: Burnout syndrome (BS) is an occupational phenomenon resulting from chronic workplace stress that has not been successfully managed. Although there are underlying causes associated with personal attributes, it is generally linked to external factors within the work environment. The aim of the present study was to investigate the impact of lifestyle factors on BS and its dimensions, as well as on suicidal ideation among Spanish professionals dedicated to implant dentistry. Methods: A cross-sectional observational study was conducted in accordance with the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) guidelines. An electronic survey based on the Maslach Burnout Inventory—Human Services Survey (MBI–HSS) was distributed to members of the Spanish Society of Implants. The data were analysed using descriptive statistical methods. Results: A total of 305 participants (20.9%) responded to the questionnaire. Notably, 10.8% of the professionals reported experiencing suicidal thoughts, a factor significantly associated with the presence of BS. The lifestyle factors associated with BS included the following: not engaging in aerobic exercise for at least 30 min per day (p < 0.05), not having hobbies that facilitate mental disconnection from work (p < 0.001), not following a balanced diet (p < 0.0001), having an insufficient social life (p < 0.0001), and experiencing suicidal ideation (p < 0.01). Conclusions: The surveyed dentists generally reported having healthy lifestyle habits. Nevertheless, one in ten professionals acknowledged having experienced suicidal ideation at some point, highlighting a concerning association with BS. Full article

Background/Objectives: Since breast cancer (BC) survival rates have increased to 91% at 5 years and 80% at 15 years postdiagnosis, there is a growing awareness of the importance of addressing the long-term well-being of patients. Consequently, integrative oncology, which combines standard therapies with complementary approaches (nutrition, mind–body practices, and lifestyle modifications), has emerged as a patient-centred model aimed at improving symptom management, treatment adherence, and overall quality of life (QoL). This study aims to demonstrate how integrative therapies can benefit body composition, phase angle, and fluid and electrolyte balance through bioelectrical impedance analysis (BIA). Methods: This study considers a patient who underwent BC surgery and was enrolled in the AMICO clinic for anamnesis, as well as their oncological pathology data, assessment of QoL, and BIA. The breast surgeon specialising in integrative oncology therapies prescribed the patient curcumin and polydatin, moderate physical activity, a balanced diet, and Qigong sessions. The patient underwent monitoring through haematochemical analysis, BIA, and a QoL questionnaire, with follow-up every four months. Results: Between 4 and 12 months, fat mass (FM) and body mass index (BMI) markedly decreased, whereas fat-free mass (FFM), total body water (TBW), and skeletal muscle mass (SMM) increased progressively. Moreover, the improvements in the Na/K ratio and phase angle (PhA) suggest a shift toward better electrolyte and fluid balance and enhanced cellular integrity and membrane function. Equally outstanding were her psychological benefits in terms of mood, sleep, anxiety, and melancholy. Conclusions: Patient progress in body composition, metabolic function, pain management, and psychological status measured during the 12-month follow-up demonstrates the potential benefits of an integrative approach to supportive cancer care.

Introduction: The sodium-to-potassium (Na:K) ratio in the diet is a critical biomarker for cardiovascular and metabolic health, yet global adherence to recommended levels remains poor. Objectives: The objective of this study was to identify dietary determinants of the dietary Na:K ratio and its associations with micronutrient intake and diet quality. Methods: An observational cross-sectional survey was conducted in a representative sample of manufacturing workers through a combined stratified proportional and two-stage probability sampling plan, with strata defined by company size and industrial sector from the state of Rio Grande do Norte, Brazil. Dietary intake was assessed using 24 h recalls via the Multiple Pass Method, with Na:K ratios calculated from quantified food composition data. Diet quality was assessed with the Diet Quality Index-International (DQI-I). Multiple linear regression was used to analyze associations of Na:K ratio with the study variables. Results: The survey was conducted in the state of Rio Grande do Norte, Brazil, in 921 randomly selected manufacturing workers. The sample mean age was 38.2 ± 10.7 years, 55.9% males, mean BMI 27.2 ± 4.80 kg/m². The mean Na:K ratio was 1.97 ± 0.86, with only 0.54% of participants meeting the WHO recommended target (<0.57). Fast food (+3.29 mg/mg per serving, p < 0.001), rice, bread, and red meat significantly increased the ratio, while fruits (−0.16 mg/mg), dairy, white meat, and coffee were protective. Higher Na:K ratios were associated with lower intake of calcium, magnesium, phosphorus, and vitamins C, D, and E, as well as poorer diet quality (DQI-I score: −0.026 per 1 mg/mg increase, p < 0.001). Conclusions: These findings highlight the critical role of processed foods in elevating Na:K ratios and the potential for dietary modifications to improve both electrolyte balance and micronutrient adequacy in industrial workers. The study underscores the need for workplace interventions that simultaneously address sodium reduction, potassium enhancement, and overall diet quality improvement tailored to socioeconomic and cultural contexts, a triple approach not previously tested in intervention studies. Future studies should further investigate nutritional consequences of imbalanced Na:K intake. Full article

Dietary patterns have been identified as one of the most important modifiable risk factors for several non-communicable diseases, inextricably linked to the health span of older people. Poor dietary choices may act as triggers for immune responses such as aggravated inflammatory reactions and oxidative stress contributing to the pathophysiology of several ageing hallmarks. Novel dietary interventions are being explored to restore gut microbiota balance and promote overall health in ageing populations. Probiotics and, most recently, postbiotics, which are products of probiotic fermentation, have been reported to modulate different signalling biomolecules involved in immunity, metabolism, inflammation, and oxidation pathways. This review presents evidence-based literature on the effects of postbiotics in promoting healthy ageing and mitigating various age-related diseases. The development of postbiotic-based therapeutics and diet-based interventions within a personalised microbiota-targeted approach is proposed as a possible direction for improving health in the elderly population. Despite growing evidence, the data regarding their exact mechanistic pathways for antioxidant and immunomodulating activities remain largely unexplored. Expanding our understanding of the mechanistic and chemical determinants of postbiotics could contribute to disease management approaches, as well as the development of and optimisation of biotherapeutics.

Background: Promoting sustainable eating is gaining increasing attention, yet the transition from intentions to actual behaviors remains unclear. This study compares the theory of planned behavior (TPB) and the theory of behavioral choice (TBC) in predicting such intentions and examines the moderating role of distress, psychological well-being, and dysfunctional eating styles in the intention–behavior relationship. Methods: A total of 223 participants from the general population (29.49 ± 9.30 years; 68.6% females) completed an online survey assessing TPB and TBC predictors, the Sustainable and Healthy Dietary Behaviors (SHDB) questionnaire, the Depression and Anxiety Stress Scale (DASS-21), the Psychological Well-Being Scale (PWBS), and the Dutch Eating Behavior Questionnaire (DEBQ). Results: The TBC model explained a significantly greater variance in intention (R² = 0.45, ΔR² = 0.28, F(215,4) = 27.27, p < 0.001) compared to the TPB, with TBC-affect (β = 0.48, p < 0.001) and felt obligation (β = 0.23, p < 0.001) being the strongest predictors. Moderation analyses revealed that the intention–behavior link was stronger in participants with lower external eating and autonomy. Conclusions: Both internal and external factors play a crucial role in predicting intentions. In addition, the intention–behavior link is stronger in individuals who are less reactive to external food stimuli and more influenced by social pressure. Promoting more balanced psychological well-being and functional eating habits may foster more sustainable diets. Full article

Background/Objectives: Growing pains are a common cause of recurrent limb pain in children, but their etiology remains unclear. Physical activity and nutrition are important factors for musculoskeletal health, but their specific relationship with growing pains has not been well established in young athletes. This study aimed to assess the prevalence of growing pains in child and adolescent athletes and evaluate their adherence to the Mediterranean Diet. Methods: A cross-sectional study was conducted with 916 athletes aged 8–17 years from sports academies in Alicante, Spain. Data were collected via an online survey assessing demographics, pain types, and adherence to the Mediterranean diet. Results: Self-reported pain was highly prevalent, affecting 78.5% of children and 93.5% of adolescents. Musculoskeletal and nocturnal pain increased with age, with nocturnal pain significantly more frequent in girls among children (p < 0.001). Additionally, 32.6% of children and 51.9% of adolescents had received a formal diagnosis of growing pains. Despite this, only 13.7% reported using analgesics, with no significant gender differences. Adherence to the Mediterranean diet was mostly moderate, with children reporting higher fruit and vegetable intake than adolescents, while adolescents consumed more healthy fats and carbohydrates, and participants without pain showed overall healthier dietary patterns. Conclusions: Idiopathic musculoskeletal pain is highly prevalent among young athletes, and their adherence to a healthy diet is suboptimal, challenging the assumption that physically active children maintain well-balanced diets. This underscores the importance of early nutritional education as a strategy to support musculoskeletal health and reduce pain in physically active youth. Full article

Researchers are increasingly focusing on understanding the microbiota’s influence on disease susceptibility and overall health. The vast number of microorganisms in our gastrointestinal tract and their extensive surface area underscore their undeniable impact on well-being. Viewing the gut microbiome as a distinct pool of microbial genetic information that interacts with the human genome highlights its pivotal role in genetically predisposed diseases. Investigating this complex crosstalk may lead to the development of novel therapeutic strategies—such as targeting dysbiosis—to complement conventional treatments and improve patient care. Parkinson’s disease (PD) is a multifactorial condition originating from a combination of genetic and environmental risk factors. Compelling evidence points to the enteric nervous system as an initial site of pathological processes that later extend to the brain—a pattern known as the ‘body-first’ model. Furthermore, most patients with PD exhibit both qualitative and quantitative alterations in the composition of the gut microbiota, including dysbiosis and small intestinal overgrowth. Nonetheless, the existing literature predominantly addresses fecal microbiota, while knowledge of upper intestinal sections, like the duodenum, remains scarce. Given the potential for microbiota modulation to impact both motor and gastrointestinal symptoms, further research exploring the therapeutic roles of balanced diets, probiotics, and fecal transplants in PD is warranted.

As tumor research has deepened, the deregulation of cellular metabolism has emerged as yet another recognized hallmark of cancer. Tumor cells adapt different biochemical pathways to support their rapid growth, proliferation, and invasion, resulting in distinct anabolic and catabolic activities compared with healthy tissues. Certain metabolic shifts, such as altered glucose and glutamine utilization and increased de novo fatty acid synthesis, are critical early on, while others may become essential only during metastasis. These metabolic adaptations are closely shaped by, and in turn remodel, the tumor microenvironment, creating favorable conditions for their spread. Anticancer metabolic strategies should integrate pharmacological approaches aimed at inhibiting specific biochemical pathways with well-defined dietary interventions as adjunctive therapies, considering also the role of gut microbiota in modulating diet and treatment responses. Given the established link between the consumption of foods rich in saturated fatty acids and sugars and an increased cancer risk, the effects of diet cannot be ignored. However, current evidence from controlled and multicenter clinical trials remains insufficient to provide definitive clinical recommendations. Further research using modern omics methods, such as metabolomics, proteomics, and lipidomics, is necessary to understand the changes in the metabolic profiles of various cancers at different stages of their development and to determine the potential for modifying these profiles through pharmacological agents and dietary modifications. Therefore, clinical trials should combine standard treatments with novel approaches targeting metabolic reprogramming, such as inhibition of specific enzymes and transporters or binding proteins, alongside the implementation of dietary restrictions that limit nutrient availability for tumor growth. However, to optimize therapeutic efficacy, a precision medicine approach should be adopted that balances the destruction of cancer cells with the protection of healthy ones. This approach, among others, should be based on cell type-specific metabolic profiling, which is crucial for personalizing oncology treatment. Full article

Background/Objectives: Recent research indicates a global transition from healthy and balanced diets to unhealthy Westernized dietary patterns (WDPs). This transition is linked to increased rates of non-communicable diseases (NCDs), e.g., obesity, type 2 diabetes, and cardiovascular diseases, often preceded by metabolic syndrome (MetS). Therefore, the objective of this study was to develop a diet quality index, termed Westernized Diet Index (WDI), to assess adherence to WDPs and its association with main cardiometabolic health issues, for which MetS and its components were chosen as representatives of NCDs. Methods: The development of the WDI was driven by a semi-systematic and comprehensive examination of the literature (n = 491 articles) that evaluated the influence of WDP components on health outcomes. The scoring algorithm involved multiple steps, assigning scores based on study design, sample size, and the direction of food effects on health outcomes. Results: The final developed index encompassed 30 food groups/items. It was revealed that soft drinks, processed foods, red meat, sodium, and hydrogenated fats had the most detrimental effects on health, significantly influencing the index’s coefficients. In contrast, dietary fiber, plant-based metabolites, vitamins, minerals, nuts/seeds, and fish had the most substantial beneficial impacts. Conclusions: The WDI aligns with the existing literature on the importance of specific food items and with other validated diet quality indices, e.g., the Dietary Inflammatory Index (DII) and Alternate Healthy Eating Index (AHEI). Thus, the WDI can provide evidence for clinicians and researchers in formulating evidence-based dietary guidelines as well as strategies for the prevention and treatment of diet-related health issues. However, further validation is proposed to verify the WDI’s capability across different contexts. Full article

Acid–base balance is critical to human health and can be significantly influenced by dietary choices. The Western diet, characterized by high meat and cheese consumption, induces excess acidity, highlighting the need for strategies to mitigate this. Recent studies have focused on bicarbonate-rich mineral water as a viable solution. In this context, the present narrative review synthesizes the findings from recent scientific studies on bicarbonate-rich mineral water, specifically those with bicarbonate levels over 1300 mg/L and medium or low PRAL values. This water has been shown to exert beneficial effects on both urinary and blood parameters. The key effects include an increase in the urine pH and a profound reduction in net acid excretion as a sign for a reduced acid load. Additionally, bicarbonate mineral water has been shown to decrease the excretion of nephrolithiasis-related constituents, including calcium and oxalates, as well as inhibitory substances such as magnesium and citrates. In blood, bicarbonate-rich water has been demonstrated to stabilize pH and increase bicarbonate levels, thereby enhancing systemic buffering capacity. Clinically, these changes have been associated with a lowered risk of calcium oxalate stone formation and improved kidney health. Furthermore, bicarbonate-rich water has been shown to support bone health by reducing bone resorption markers. Consequently, the integration of bicarbonate-rich mineral water into the diet has the potential to enhance urinary and blood parameters, mitigate the risk of kidney stones, and strengthen skeletal integrity, thereby serving as a promising strategy for health promotion and disease prevention. While promising, these findings underscore the need for further research to establish long-term recommendations. Future interventional studies should be designed with rigorous randomization, larger sample sizes, cross-over methodologies, and comprehensive dietary assessments to address the methodological limitations of previous research.

Metabolic dysfunction-associated steatotic liver disease (MASLD) and its progressive form, metabolic dysfunction-associated steatohepatitis (MASH), are growing global health concerns. However, pharmacological therapies for MASLD/MASH have not yet been established. Dietary interventions and their bioactive components have been explored as strategies to mitigate MASLD and MASH progression. Although specific nutrients and bioactive compounds have exhibited potential therapeutic benefits, they also exacerbate adverse outcomes. In this comprehensive review, we synthesize the protective and exacerbating or sometimes dual effects of key macronutrients, including fatty acids (saturated, unsaturated, and trans fats) and carbohydrates (fructose, glucose, and sucrose), and bioactive compounds and micronutrients, in the context of MASLD management. The evidence suggests that coffee-derived compounds, such as caffeine and chlorogenic acid, may attenuate liver injury. However, the effects on MASLD severity are inconsistent. Diets high in saturated fatty acids exacerbate MASLD pathogenesis, whereas moderate intake (7–10% of total energy) may confer metabolic benefits. Other bioactive compounds and micronutrients have been explored for their diverse roles in hepatic lipid metabolism and insulin sensitivity. Although current evidence supports the therapeutic potential of specific dietary nutrients and bioactive compounds in the management of MASLD, inconsistencies in results highlight the need for more robust, well-controlled studies, including clinical trials, to clarify the preventive and therapeutic standards for balanced food interventions in MASLD management. In particular, well-designed clinical trials are necessary before clinical application. Although this is a narrative review and the literature retrieval may be biased, we covered a wide variety of substances. Full article

Background: The current study aimed to evaluate the effects of the supplementation of protease sources on growth and carcass response, gut health, nutrient digestibility, and cecal microbiota profiles in broilers fed poultry-by-product-meal (PBM)-containing diets. Methods: In total, 800 one-day-old mixed-sex broilers (Arbor Acres) were weighed and allocated to one of the four dietary treatments in a completely randomized design, with eight replicates and 25 birds each per replicate. The treatments were as follows: (1) T₀, control diet (without protease supplementation and 3% PBM); (2) T₁, control diet supplemented with acidic protease at 100 g/ton (50,000 U/g); (3) T₂, control diet supplemented with alkaline protease at 200 g/ton (25,000 U/g); (4) T₃, control diet supplemented with neutral protease at 200 g/ton (25,000 U/g). Results: Protease supplementation enhanced (p < 0.05) body weight gain and the feed conversion ratio, predominantly in broilers fed PBM-based diets containing alkaline protease. Alkaline protease supplementation increased (p < 0.05) the apparent ileal digestibility of proteins (AIDP) by 4.3% and the apparent ileal digestibility of amino acids (AIDAA) by up to 5.8%, except for ornithine. Increments (p < 0.05) in carcass, breast, and leg quarter yields due to protease supplementation were evident, particularly in broilers fed diets containing alkaline protease. Alkaline protease improved (p < 0.05) the duodenal villus height (VH), reduced the crypt depth (CD), and increased the villus height to crypt depth ratio (VCR). Alkaline protease supplementation reduced (p < 0.05) cecal counts of Salmonella, Escherichia coli, and Clostridium in the broilers, whereas it increased (p < 0.05) the Lactobacillus counts. Conclusions: the supplemented alkaline protease resulted in improved growth performance and carcass traits, better gut health, as well as improved ileal digestibility of nutrients, including crude protein (CP) and acid insoluble ash (AIA), with a more balanced cecal microbial composition in broilers.

Background/Objectives: Access to nutritious and well-balanced food is essential for well-being. We investigated the relationship between food insecurity (FI) and cardiovascular health (CVH). Methods: This cross-sectional analysis included a nationwide sample consisting of 12,369 Korean adults. The 18-item Household Food Security Survey Module was employed to evaluate FI, with categories ranging from none, to mild, to moderate-to-severe. CVH was assessed through the “Life’s Essential 8” (LE8) framework established by the American Heart Association. This framework includes four health behaviors (diet quality, exercise, tobacco use, and sleep) and four biometric factors (body mass index, blood lipids, blood glucose, and blood pressure). Overall, CVH was scored on a scale from 0 to 100 and categorized into ideal (LE8 score: 80–100), intermediate (LE8 score: 50–79), and poor CVH (LE8 score: 0–49). Multivariate linear and logistic regression models were used to determine the association of FI with CVH status. Results: Within the sample, 3.7% and 0.8% experienced mild and moderate-to-severe FI, respectively. Compared with those without FI, individuals with mild (β: −2.92; 95% CI [confidence interval]: −4.37, −1.48) or moderate-to-severe (β: −7.71; 95% CI: −11.22, −4.20) FI had lower LE8 scores. Additionally, those with mild or moderate-to-severe FI were more likely to have poor CVH status (OR [odds ratio]: 2.14; 95% CI: 1.33, 3.66 for mild FI and OR: 4.83; 95% CI: 1.64, 14.17 for moderate-to-severe FI). Conclusions: FI is negatively associated with CVH in Korean adults. These findings underscore the need for comprehensive policy interventions to enhance food access and promote CVH in this at-risk population. Full article

Biscuits are widely consumed snacks traditionally made from wheat flour, which poses challenges for individuals with gluten intolerance and/or diabetes due to their high glycaemic index (GI). This study explored the production of gluten-free biscuits using rice flour from two varieties, Type III (Basmati) and Ariete (Long A), incorporating varying proportions of rice bran as a substitute for milled and brown rice flour. Results show that biscuits made with rice bran had lower starch digestibility and reduced GI (57.06–62.75) compared to control biscuits (66.23–66.95). Rice bran also increased bioactive compounds, such as phytic acid (0.16 to 1.96 g/100 g), γ-oryzanol (0.20 to 86.56 mg/100 g), and γ-aminobutyric acid (6.78 to 16.23 mg/100 g), known for their benefits to diabetes metabolism. Physicochemical analysis further revealed higher protein (6.49%) and lower starch content (30.07%) in rice bran biscuits than in control biscuits (4.20% and 47.38%, respectively). The control biscuits exhibited the highest spread ratio (5.90 and 6.35) and the Ariete variety produced less brittle biscuits (168.30 N), although the addition of bran increased brittleness under cutting force (54.55 N). Sensory evaluation of four rice biscuit formulations showed no significant differences in consumer preferences, regardless of flour type, bran proportion, or rice variety. Among the formulations, the Type III biscuits with an equal blend of milled flour and rice bran stood out, offering improved nutritional quality and a promising option for gluten-free, low-GI diets for consumers seeking healthier alternatives. This formulation also proved a strong balance across key nutritional and bioactive parameters, when compared to a commercial wellness biscuit. Full article

Essential fatty acids are extremely important nutrients in the diet of fish, and the balance between arachidonic acid (ARA) and eicosapentaenoic acid (EPA) is crucial for the healthy growth of fish. Six isonitrogenous and isolipidic basal diets were given to 540 juvenile fat greenling (Hexagrammos otakii) (31.4 ± 1.5 g) for 8 weeks to investigate the effects of dietary ARA/EPA ratio on growth performance, antioxidant capacity and lipid metabolism-related genes of juvenile H. otakii. The control group (A) had 7% fish oil added as the main fat source, while the experimental groups had 4% fish oil as the basic fat source, with varying proportions of ARA and EPA concentrates added to formulate five diets with varying ARA/EPA ratios (B 2.66; C 1.34; D 1.01; E 0.47; F 0.19). The experimental results revealed that adding ARA and EPA to the diet increased the percent weight gain (PWG) and feed conversion ratio (FCR) of juvenile H. otakii, and the PWG and FCR were greatest under Group E dietary conditions. The specific activities (U/mg protein) of superoxide dismutase (SOD), catalase (CAT), and total antioxidant capacity (T-AOC) in the liver, as well as serum SOD and CAT were significantly higher in Groups D and E than those in other groups (p < 0.05). Malondialdehyde (MDA, nmol/g protein) content in the liver and serum was significantly lower in Group E than that in other groups (p < 0.05). Moreover, groups D and E exhibited significant increases in the specific activities (U/mg protein) of intestinal trypsin, lipase, and amylase, as well as in the intestinal villus length (p < 0.05). The incorporation of ARA and EPA into the feed reduced the expression levels of fat synthesis genes such as fas, scd1, accα, and srebp1, as well as the expression of lipolysis genes atgl and hsl. However, it also increased the expression of the lipolytic genes cpt1 and ppara. The ARA/EPA ratios in the dietary were 0.47 and 1.01, respectively, which are appropriate for enhancing growth efficiency, antioxidant enzyme activity, intestinal digestive enzyme activity and lipid metabolism regulation.
