Background/Objectives: Atherosclerosis is a major contributor to ischemic cardiovascular diseases (CVDs) such as myocardial infarction and stroke, which are leading causes of mortality and morbidity. The management of atherosclerosis through personalized nutrition has gained importance in recent years due to advancements in nutrigenomics, gut microbiome evaluation, and metabolomics. However, no systematic review has comprehensively evaluated the impact of personalized nutrition interventions on atherosclerotic plaque progression and clinical outcomes in humans. Methods: We adopted a systematic approach based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Key databases like PubMed, Cochrane, Google Scholar, and MEDLINE via EBSCOhost were searched using predefined terms related to personalized nutrition, atherosclerosis, nutrigenomics, and clinical outcomes. Results: Evidence evaluation using the framework of Boffetta et al. for cumulative evidence on the joint effects of genes and environments strongly suggested significant diet–gene interactions. Polymorphisms in the apolipoprotein A-II (APOA2) gene have been shown to influence body mass index and lipid levels. Furthermore, studies have demonstrated that omega-3 polyunsaturated fatty acids (PUFAs) can modulate microRNA expression, thereby impacting lipid metabolism. Epigenetic studies showed that dietary components can modify histone acetylation and non-coding RNA activity, which ultimately influence gene expression related to inflammation and lipid metabolism, improving clinical outcomes in atherosclerosis management. Conclusions: Integrating personalized nutrition into clinical practice promises to enhance atherosclerosis outcomes through targeted dietary interventions. Advancements in personalized nutrition offer a promising pathway toward more effective and personalized approaches to cardiovascular health. Full article

Background/Objectives: Sarcopenia is characterized by the progressive loss of skeletal muscle mass and function. Little is known about the dietary patterns and sarcopenia association. The aim of this systematic review and meta-analysis was to evaluate the association between dietary patterns and the risk of sarcopenia in adults over 50 years old, using the European Working Group on Sarcopenia in Older People, EWGSOP1 and EWGSOP2 criteria. Methods: This review followed PRISMA guidelines and was registered in PROSPERO (CRD42024423323). A systematic search was conducted in PubMed, Web of Science, and Cochrane Library (July 2024–February 2025). Observational studies in adults aged 50–85 years assessing a priori or a posteriori dietary patterns were included. Odds ratios (ORs) and 95% confidence intervals (CIs) were extracted. A random-effects model was used for meta-analysis. I² and meta-regression was performed to explore heterogeneity sources. Methodological quality was assessed with the Joanna Briggs Institute (JBI) checklist. Results: Eleven studies were included (n = 257–3432). The pooled analysis showed a significant 24% risk reduction in sarcopenia with healthy dietary patterns (OR = 0.76, 95% CI: 0.63–0.92, I² = 56.2). Unhealthy dietary patterns did not show a significant association (OR = 1.04, 95% CI: 0.66–1.63). Mediterranean (MD) pattern yielded the strongest effect (OR = 0.62, 95% CI: 0.40–0.95). Meta-regression analyses did not identify significant variables. Conclusions: Healthy dietary patterns, particularly the MD, are associated with a lower risk of sarcopenia in adults over 50 years old and represent a promising nutritional strategy for sarcopenia prevention.

Background/Objectives: The impact of nutritional interventions on Sjögren disease (SD) remains uncertain, and no standardized guidelines currently exist for managing its sicca symptoms. This systematic review evaluated the effects of dietary interventions on the symptoms of dry mouth and dry eyes in individuals with SD. Methods: Electronic searches were performed in four databases, supplemented by manual searches and searches of the gray literature. Both human and animal studies were included. The methodological quality of the selected studies was appraised, and the data were analyzed descriptively. Results: A total of nineteen studies (ten in humans and nine in animal models) were included. The treatments evaluated were dietary supplements, vitamins, medicinal herbs, and specially modified diets. The primary outcomes assessed included unstimulated and stimulated whole salivary flow rates, salivary-gland inflammation, and ocular dryness (Schirmer test). In animal models of SD, interventions such as caloric restriction, gluten-free diets, low-fat diets, and supplements (e.g., resveratrol, triptolide, and Lycium barbarum polysaccharide) were associated with increased salivary flow and reduced glandular inflammation. Conversely, diets rich in saturated fats were associated with reduced salivary flow and increased lymphocytic infiltration in salivary glands. Human studies yielded mixed results, with some reporting improvements in salivation following interventions with vitamins, herbal supplements, gluten-free diets, liquid diets, and whole-food, plant-based diets. Conclusions: Although dietary management may alleviate sicca symptoms and improve nutritional status in SD, the current evidence is insufficient to support specific recommendations for the management of oral symptoms.

Introduction: Recent guidelines developed by the European Association for the Study of Obesity (EASO) and the European Federation of the Associations of Dietitians (EFAD) focused on the dietetic management of obesity in adults. The present study aimed to explore the perspectives of healthcare professionals regarding these guidelines. Methods: In total, 85 registered dietitians/nutritionists from Greece, the Netherlands, the Republic of Ireland, and the United Kingdom completed an online survey, and 10 were interviewed, in February–March 2023. Demographic data were also collected. Results: Awareness of the EASO-EFAD guidelines among registered dietitians/nutritionists was moderate (57.6%), but only 20% had read them in full. Dietitians with higher education and relevant experience were more likely to have read the guidelines. Less than half reported that key evidence-based recommendations, such as individualized medical nutrition therapy and intensive behavioral interventions, are already included in national guidance. Recommendations like portfolio or DASH diets, partial meal replacements, and calorie restriction were less commonly part of national guidance/usual practice. A small percentage of participants described their adoption of several nutritional approaches novel to them. These included the portfolio dietary pattern, partial meal replacements, and intermittent fasting or continuous calorie restriction. For some Irish dietitians, prioritizing weight as the main outcome conflicted with their emphasis on overall health and individualized nutrition therapy. Other barriers of recommendation implementation included exclusive availability in English, rapid changes in obesity management, staffing shortages, limited multidisciplinary collaboration, and inconsistent knowledge among healthcare providers. Conclusions: The present study identified gaps in the adoption of the EASO-EFAD guidelines into dietetic/clinical practice. EFAD will develop strategies to disseminate these guidelines at different levels of stakeholders (national/local authorities, dietitians/nutritionists, and patients). Full article

Background: The Dietary Guidelines for Americans (DGA) and the American Academy of Pediatrics recommend limiting 100% juice consumption to 0.5–1.25 cups/day and to no more than one half of total fruit intake. Objective: To explore the dietary benefits of consuming 100% fruit juice and diluted 100% juice across diverse socio-demographic strata in the US. Methods: Consumption patterns for 100% juice and diluted 100% juice were examined by sex, age group, income-to-poverty ratio (IPR), and race/ethnicity. Dietary intakes came from the National Health and Nutrition Examination Survey (NHANES 2017–2020 and 2021–2023). The Healthy Eating Index 2020 (HEI 2020) and diet-level Nutrient Rich Food (NRF9.3) scores were the two measures of diet quality. The amounts of 100% juice consumed were compared to published DGA recommendations. Results: The consumption of 100% juice was greatly below that of water, milk, and sugar-sweetened beverages (SSBs). The consumption of diluted 100% juice was very low. Consumers of 100% juice had higher HEI 2020 scores (53 vs. 48) and diets with less added sugar and more total fruit, more potassium, calcium, and vitamin C. About 88% of the NHANES sample consumed <4 oz/day (1/2 cup) of 100% juice and most derived at least 50% of fruit from whole fruit, though some variation by income and race/ethnicity was observed. About 93% of the sample consumed <1 cup/day (8 oz) of 100% juice. Lower income groups consumed less whole fruit and more 100% juice. Conclusion: The consumption of 100% fruit juice was a marker of healthier dietary choices. The observed social gradient suggests that 100% fruit juice may provide valuable nutrients to populations who may be unable to afford or access whole fruit. Public health recommendations: The consumption of 100% fruit juice by some population subgroups could be increased. Fruit juice was not displacing whole fruit, and current consumption was well below the current DGA recommended values. Full article

This review focuses specifically on pediatric patients with cystic fibrosis. Cystic fibrosis (CF) is a serious inherited disease that affects the respiratory and gastrointestinal systems in children and adolescents, causing chronic inflammation, infections, and impaired nutrient absorption. A key component of patient care is monitoring nutritional status, particularly based on BMI, which correlates with lung function and life expectancy. This paper presents the latest guidelines for dietary therapy, including a high-calorie and fat-rich diet supported by pancreatic enzymes, as well as the importance of vitamin and mineral supplementation in the context of CF pathophysiology. The role of modern therapies that modulate CFTR function to improve patients’ quality of life and support antimicrobial therapy is discussed. Particular attention is paid to the role of the gut microbiota and the potential for its modulation by probiotics, highlighting their potential to alleviate inflammation and support the immune system. The conclusions underscore the need for a comprehensive, individualized approach to diagnosis and therapy, which is crucial for improving the quality of life and health prognosis of children with CF. New visual tools and a clinical case study enhance the practical applicability of current recommendations, while emerging areas such as microbiome-targeted interventions and treatment inequalities are also addressed.

Background/Objectives: Poor nutritional status and cachexia have been well-documented as predictors of adverse outcomes in individuals with chronic heart failure (HF). However, despite obesity being a common observation in this patient population, a growing body of evidence indicates that these individuals may still suffer from nutrient deficiencies and malnutrition. This study aimed to characterize the food and nutrient intake of participants enrolled in the Pro-HEART clinical trial—a study evaluating dietary interventions in overweight and obese individuals with HF—and to compare their consumption patterns to national nutritional guidelines. Methods: A cohort of 92 overweight and obese individuals with chronic HF enrolled in the Pro-HEART trial. Baseline food consumption was assessed via a validated 3-day Food Record. The data were analyzed using descriptive statistics to evaluate adherence to recommended intake levels for energy, macronutrients (fat, carbohydrates, protein), and key micronutrients. Results: Among the 92 participants, 41% exceeded fat intake recommendations, 73% surpassed guidelines for saturated fat, and 95% consumed excessive sodium. Despite adequate caloric intake, many individuals failed to meet recommended levels for key micronutrients known to influence inflammation and metabolic regulation, including vitamin D, calcium, magnesium, and potassium. Conclusions: These findings suggest that overweight and obese individuals with HF, despite their excess body weight, exhibit dietary patterns that place them at risk of malnutrition. The results underscore the necessity of nutritional assessments and interventions in this population to address deficiencies that may contribute to the metabolic and inflammatory abnormalities associated with HF.

Background: Grain foods are important sources of complex carbohydrates, fiber, vitamins, and minerals. Objective: To identify healthy grain foods and to assess their associations with composite diet quality measures and selected health outcomes. Methods: Healthy grain foods were identified using two methods. The first one, Carbohydrate Food Quality Score (CFQS-3) was based on whole grains, fiber, and added sugar. The second, NRF9.3g score for grains, balanced nutrients to encourage (protein, fiber, vitamins B1, B2, B3, and E, folate, iron, and magnesium) against added sugar, sodium, and saturated fat. Nutrient composition data for 1244 grain foods came from the USDA Food and Nutrient Database for Dietary Studies (FNDDS 2017–2023). Dietary intakes came from the National Health and Nutrition Examination Surveys (NHANES 2017–2023). The Healthy Eating Index (HEI 2020) and the diet-level Nutrient Rich Food Index (NRF) were the two measures of diet quality. National food prices came from the USDA 2021 Thrifty Food Plan. Data on body weight, waist circumference, insulin, and cholesterol came from NHANES clinical files. Results: Healthy grain foods were those that scored >2 points on CFQS-3 or were in the top tertile of NRF9.3g scores. The CFQS-3 score favored cooked whole grains and cereals and savory snacks. The NRF9.3g score gave the highest ratings to breads, rolls, and RTE cereals. Consumers of healthy grains identified using both methods had higher HEI 2020 values and higher diet-level NRF scores. Both effects were dose-dependent. Consumption of healthy grains was associated with lower obesity rates and lower fasting insulin levels. Conclusions: Consumption of healthy grain foods was associated with healthier diets and lower obesity prevalence. Dietary guidelines need to acknowledge the contribution of healthy grain foods to diet quality and health. Full article

Background/Objectives: Seaweeds have recently gained global attention as sustainable and health-promoting food sources. However, seaweeds contain iodine. While iodine is a beneficial micronutrient, its excessive intake can pose health risks. Therefore, ensuring iodine safety has emerged as a critical priority. The present study aims to determine the total iodine content in five major edible seaweeds, namely laver (Porphyra spp.), sea mustard (Undaria pinnatifida), sea tangle (Saccharina japonica), green laver (Enteromorpha spp.), and hijiki (Hizikia fusiforme), collected from 12 coastal regions in South Korea during 2020–2024. Methods: A total of 348 samples were analyzed using inductively coupled plasma mass spectrometry following microwave-assisted digestion. A risk assessment was performed based on the estimated daily intake and hazard index (HI) using both the Korean Ministry of Food and Drug Safety (MFDS), EFSA (European Food Safety Authority), and the Joint FAO/WHO Expert Committee on Food Additives (JECFA) reference values. Results: The iodine content varied widely among the different species, with sea tangles exhibiting the highest levels (mean 2432 mg/kg dry weight). The HI values were all below 1.0, based on MFDS standards, indicating a low potential health risk. However, sea tangle exhibited values exceeding 1.0 based on the EFSA and JECFA standards. Conclusions: These findings highlight the need for species-specific iodine intake guidelines and safety regulations to ensure consumer protection and facilitate global seaweed trade. The present study provides a scientific basis for balancing the nutritional benefits of seaweed with the potential risks of overconsumption, contributing to the development of national dietary guidelines and providing evidence-based data for navigating international regulatory landscapes.

Background/Objectives: Naringin, a major flavonoid found in citrus fruits, has garnered significant attention over the past two decades for its potential cardiovascular benefits. This systematic review evaluates the effects of naringin on endothelial function and myocardial performance, with particular emphasis on ischemia-reperfusion (I/R) injury, based on the literature published from January 2000 to June 2025. Methods: The review was conducted in accordance with PRISMA 2020 guidelines. A comprehensive search of PubMed, Scopus, EMBASE, and Web of Science databases was performed using key terms including “naringin”, “cardiovascular”, “endothelial function”, “atherosclerosis”, and “ischemia-reperfusion.” A total of 62 studies were included and categorized into three domains: cellular models, animal studies, and human trials. Risk of bias assessments were conducted for each study type using appropriate tools. Results: Naringin consistently exhibited antioxidant, anti-inflammatory, and vasoprotective effects across all study types. Mechanistic studies highlighted the modulation of key signaling pathways, including PI3K/Akt, NF-κB, Nrf2, the renin-angiotensin system (RAS), and enhancement of KATP channel expression, as well as its ability to inhibit apoptosis, autophagy, and ferroptosis. In animal models, naringin improved endothelium-dependent vasorelaxation, reduced infarct size, and preserved myocardial function. Although limited, human trials reported beneficial effects on lipid profiles, arterial stiffness, and adiponectin levels. Conclusions: Naringin demonstrates strong potential as a dietary adjunct for cardiovascular protection, especially in the context of ischemic injury and vascular dysfunction. Further well-designed clinical trials are needed to define optimal dosing strategies and improve its bioavailability in humans. Full article

Metabolic acidosis is a common complication of chronic kidney disease (CKD). The kidneys play a crucial role in acid–base balance, maintaining pH within the normal range (isohydria) by following mechanisms: bicarbonate reabsorption, ammogenesis, and titratable acidity. The anion gap describes the amount of unmeasured anions and is classically evaluated as the difference between the major cation (sodium) and the sum of the two major anions (chloride and bicarbonate). Metabolic acidosis can be divided into two types: normal anion gap metabolic acidosis and high anion gap metabolic acidosis. A high anion gap level is considered unfavorable in terms of prognosis as it is associated with increased mortality. Treatment of metabolic acidosis in patients with chronic kidney disease, despite available therapeutic options, is a challenge. Supplementation with bicarbonates does not improve prognosis on the one hand, and on the other hand, it may be harmful. The new KDIGO guidelines for 2024 have been significantly modified compared to 2012 after negative results of studies on bicarbonate supplementation. Bicarbonate supplementation is currently recommended only when levels are less than 18 mmol/L. This review provides an overview of the current knowledge on the pathophysiology, classification, and therapeutic options, including dietary recommendations and new pharmacology agents. Full article

This study examines the relationship between dietary patterns, specifically the Mediterranean diet (MD) and the Western diet (WD), and sensory perception among nursing students at the University of Valladolid, Spain. The study aims to understand how these dietary patterns affect taste sensitivity and preferences, contributing to the fields of nutrition and sensory science. Materials and Methods: A total of 41 students participated in this study, following ethical guidelines. Food-grade materials such as refined salt, sucrose, monosodium glutamate, water, and breadsticks were used in sensory assessments. The study involved structured sensory evaluations along with dietary habit questionnaires. Sensory tests were conducted to measure taste perception, and statistical analyses were performed using IBM SPSS Statistics 25.0, with descriptive statistics and correlation analysis. Results: The findings revealed significant differences in taste perception across diet adherence levels. Specifically, higher adherence to the MD was associated with a higher perceived intensity and enjoyment of saltiness and umami, while a higher adherence to the WD showed a preference for sweetness. Significant correlations were found between diet adherence and taste enjoyment, with stronger positive associations for saltiness and umami under the MD. Conclusions: This study emphasized the impact of dietary habits on taste perception. Adherence to the MD enhanced sensitivity to moderate taste intensities, while adherence to the WD resulted in decreased perception at lower concentrations and heightened sensory responses at higher intensities. These results suggest that long-term dietary patterns influence taste receptor adaptation, potentially affecting food choices and overall health. Full article

Background: Adequate hydration for preschool children (36–72 months) is critical for their healthy growth, cognitive development, and long-term well-being. However, there is still a lack of reliable baseline data in China to inform water intake guidelines for this age group. Methods: In this study, a cross-sectional analysis was conducted using data from the 2018–2019 Dietary Survey of Infants and Young Children in China, including 676 healthy preschool children. Water and energy intake were estimated using four-day food diaries. Their daily total water intake (TWI) and total energy intake (TEI) were evaluated, and the contributions of beverages and foods to TWI and TEI were analyzed, respectively. The TWI was compared with the adequate intake (AI) set by the Chinese Nutrition Society, and the correlations between water and energy intake were explored. Results: The results show that the median daily TWI was 1218 mL, with 667 mL (55.7%, r = 0.824) from beverages and 520 mL (44.3%, r = 0.691) from foods. Among beverages, plain water (74.4%, r = 0.903) and milk and milk derivatives (MMDs, 20.9%, r = 0.443) were the main contributors, while staple foods, dishes, and soup contributed the majority of the water from foods. Only 19.4% of children’s TWI met the AI level, and their water and energy intake was significantly higher than those who did not. The median daily TEI was 994 kcal, with 739 kcal (77.2%, r = 0.806) from foods and 198 kcal (22.8%, r = 0.644) from beverages. MMDs accounted for 83.1% of beverage energy (r = 0.880). Boys consumed more beverages than girls, especially in the 37–48 months group. Conclusions: As the first nationally representative study of TWI among Chinese preschool children, these findings reveal a substantial gap between actual intake and current recommendations, and highlight the need to revise reference values and improve hydration guidance in early childhood.

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: Hyperemesis gravidarum (HG) is the leading cause of hospitalization during early pregnancy, affecting approximately 0.3–3% of pregnancies. It represents the most severe end of the nausea and vomiting in pregnancy (NVP) spectrum and is associated with substantial maternal morbidity and potential adverse fetal outcomes. Despite extensive research, the exact pathophysiology remains poorly understood, and optimal management strategies continue to be debated. Methods: This narrative review synthesizes current evidence on the complications and treatment approaches for HG. A literature search was conducted in PubMed, Scopus, and Medline up to October 2024 using predefined keywords. Eligible sources included observational studies, cohort studies, descriptive studies, and case reports. Systematic reviews, meta-analyses, and non-English articles were excluded. Results: HG is associated with a broad spectrum of complications, including dehydration, electrolyte imbalances, Wernicke’s encephalopathy, cardiac arrhythmias, thromboembolism, and adverse pregnancy outcomes such as fetal growth restriction and preterm birth. Pharmacological treatments—most notably doxylamine-pyridoxine (the only FDA-approved therapy), ondansetron, metoclopramide, and corticosteroids—have demonstrated varying efficacy and safety profiles. Non-pharmacological interventions such as acupressure, dietary adjustments, psychotherapy, and hypnosis have also been studied, although evidence remains limited. Conclusions: HG requires a comprehensive and individualized management approach. While doxylamine-pyridoxine remains the cornerstone of therapy, other pharmacologic and supportive measures may offer additional benefit. Continued research is essential to clarify the underlying mechanisms, improve therapeutic efficacy, and develop evidence-based guidelines that integrate both medical and psychosocial care for affected women.
