The gut microbiome supports both gut and overall health. Diet is known to be one of the driving factors that influences the gut microbiome. The foods we eat, the dietary and nondietary components they contain, various food consumption patterns, and the ratio of nutrients consumed have been shown to impact gut microbiome composition and function. Studies indicate that many acute and chronic diseases are associated with alterations to the gut microbiome. There are many patients who rely on enteral tube feeding for their nutrition support. More recently, enteral tube feeding formulations of "real food" have become commercially available. However, little is known about how enteral tube feeding impacts the gut microbiome in patients requiring this specialized form of nutrition therapy. This review summarizes the existing evidence regarding the food sources of commonly consumed macronutrients and their impact on the gut microbiome. Also presented is what is known regarding "standard" and real food enteral formulations on the gut microbiome. Existing evidence is suggestive that real food enteral formulations positively impact the gut microbiome. Still, more research is needed on ready-to-feed formulations, particularly in patients with various clinical conditions, and how gut microbiome modulation impacts clinical outcomes.

To investigate the independent and comprehensive association between plant-based diets and activities of daily living (ADL) in older Chinese individuals, we conducted a longitudinal study to evaluate the relationship between the plant-based diet index (PDI) and ADL in this population.

This study included 18,670 participants (women [proportion]: 9899 [53.0%]) who were able to independently conduct ADL at baseline in the 1998-2018 China Longitudinal Survey of Health and Longevity (CLHLS). The Cox proportional hazard model was used to test the association between a plant-based diet and activities of daily living-related disabilities.

At baseline, the median age of all participants was 83 years old. Taking Q1 as the reference value, the hazard ratios (HR) for quartiles Q2, Q3, and Q4 were 1.080 [95% confidence interval (CI) 1.018-1.147], 1.086 (95% CI 1.007-1.181), and 1.110 (95% CI 1.038-1.187), respectively. This indicated that a higher PDI might have had adverse effects on ADL. Adjustments have been made to the potential inclusion population and data processing strategies, as well as to the frequency of intake based on nutritional factors. Subsequently, it was found that the obtained results were consistent with the preliminary analysis.

This study found that a higher plant-based diet was associated with an increased risk of disability in daily activities, while the intake of meat and fish was associated with a decreased risk. These findings highlight the importance of dietary balance in plant-based diets.

Background/Objectives: Evidence suggests that plant-based dietary patterns are beneficial for cardiometabolic health. However, it is unclear whether the quality of plant-based dietary patterns is differentially associated with cardiometabolic health. This study aimed to examine the association between three plant-based diet quality indices and cardiometabolic health among Australian adults. Methods: Data on 4877 adults (mean 45.1 years) from the cross-sectional Australian Health Survey 2011-2013 were used. Three plant-based diet quality indices (overall, healthful, and unhealthful) were derived from two 24 h dietary recalls. Anthropometric measures and blood pressure were assessed by trained interviewers. High-risk waist circumference was classified as ≥80 cm in females and ≥80 cm in males. Hypertension was defined as >140/90 mmHg. Fasting blood samples were used to estimate lipid profiles and diabetes status (based on plasma glucose or HbA1c). Multivariate logistic regression analyses were used to investigate the association between plant-based diet indices and cardiometabolic markers. Results: The healthy plant-based diet index was associated with lower odds of a high-risk waist circumference (OR 0.98; 95%CI 0.96-0.99), and the unhealthy plant-based diet index was associated with increased odds of having hypertension (OR 1.02; 95%CI 1.00-1.04). No other significant associations were identified between the plant-based diet quality indices and cardiometabolic outcomes. Conclusions: There was some evidence that the quality of plant-based dietary patterns was differentially associated with cardiometabolic health, with healthier plant-based dietary patterns associated with lower odds of a high-risk waist circumference, and less healthy plant-based dietary patterns associated with increased odds of hypertension. These findings support the consideration of the quality of plant foods consumed, and the need for targeted advice for optimising cardiometabolic health among adults.

Cardiovascular diseases (CVDs) are the leading cause of mortality worldwide. This narrative review explores the relationship between macronutrient intake and CVD risk, focusing on carbohydrates, proteins, and fats. The goal is to examine how specific types of macronutrients influence cardiovascular health and how dietary guidelines, such as those from the World Health Organization (WHO), can reduce the incidence of both fatal and non-fatal cardiovascular events.

This narrative review draws upon existing research and WHO dietary guidelines to assess the impact of various macronutrients on cardiovascular outcomes. We searched the relevant literature up to December 2024 using Pubmed and Google Scholar. Key macronutrient groups-carbohydrates (with a focus on glycemic index and glycemic load), proteins (plant-based vs. animal-based), and fats (saturated, trans, polyunsaturated, and monounsaturated)-were analyzed to understand their roles in CVD prevention.

Low glycemic index (GI) and glycemic load (GL) were found to be associated with reduced CVD risk. Protein intake showed no significant direct association with CVD risk, but higher consumption of plant-based proteins was correlated with a reduced risk. Replacing animal proteins with plant-based alternatives led to improved lipid profiles, including reductions in total and low-density lipoprotein (LDL) cholesterol levels. Fats, particularly saturated and trans fats, were strongly linked to increased CVD risk. WHO guidelines recommend limiting these fats and replacing them with healthier alternatives, such as polyunsaturated and monounsaturated fats or slow-digesting carbohydrates, to lower CVD risk.

Macronutrients play a critical role in cardiovascular health, with specific types of carbohydrates, proteins, and fats having varying impacts on CVD risk. Future research should explore the complex interactions between these macronutrients, dietary patterns, and cultural factors to optimize global dietary guidelines for CVD prevention. Replacing high-GI carbohydrates, saturated fats, and trans fats with healthier alternatives is crucial for reducing cardiovascular risk globally.

Background/Objectives: Plant-based diets are associated with human and planetary health. However, the overall quality of these diets may depend on the proportion of ultra-processed foods (UPFs). This study investigates the association between UPF consumption and plant-based diet quality in Australian adults. Methods: Analysis was conducted on 9111 participants (aged ≥ 19 years) from the National Nutrition and Physical Activity Survey 2011-2012. Food items reported from a 24 h recall were classified using the NOVA system, and the contribution of UPFs to total energy intake was calculated. Plant-based diet quality was examined using the overall plant-based diet index (PDI), healthy PDI (hPDI), and unhealthy PDI (uPDI). Multiple linear regression models were used to examine the association between the UPF intake and PDI, hPDI, uPDI, and their score components. Results: The proportion of energy from UPFs was positively associated with the uPDI (β = 0.80; 95% CI 0.72, 0.89) and negatively associated with the PDI (β = -0.13; 95% CI: -0.22, -0.04) and the hPDI (β = -0.65; 95% CI: -0.73, -0.57). All score components of the PDI, hPDI and uPDI, except whole grains, legumes and fruit juices, significantly contributed to these associations. The sugars and syrups group contributed most to the positive association between UPFs and the uPDI (β = 6.47; 95% CI: 6.07, 6.87) and the negative association of UPFs and the hPDI (β = -6.47; 95% CI: -6.07, -6.87). Conclusions: Higher consumption of UPFs was associated with a lower plant-based diet quality. These findings have implications for the design of dietary interventions that encourage the consumption of minimally processed plant-based foods.

Consumption of different food groups is linked to a range of health outcomes. It is essential to integrate the most reliable evidence regarding intake of different food groups and risk of mortality to optimize dietary guidance. Our aim is to systematically and comprehensively assess the associations between the consumption of various food groups and all-cause mortality. The food groups under consideration include edible grains (refined and whole grains), fruits, vegetables, nuts, legumes, fish and fish products, eggs, dairy products/milk, meat and meat products (including processed meat, unprocessed red and white meat), sugar-sweetened beverages, and added sugars. We present these associations with high compared with low consumption and per serving comparisons. We comprehensively and systematically reviewed a search in Medline, Embase, Web of Science, and Epistemonikos (PROSPERO: CRD42024498035), identifying 41 meta-analyses involving over a million participants, many of which showed significant heterogeneity. Of the 41 studies, 18 were rated high quality, 8 moderate quality, 5 low quality, and 10 critically low quality according to AMSTAR-2 assessments. Our findings revealed that higher consumption of nuts, whole grains, fruits, vegetables, and fish was associated with lower mortality rates, both in high compared with low comparisons and per serving analyses. Similarly, we observed favorable outcomes for legumes and white meat in high compared with low comparisons. Conversely, high intakes of red and processed meats, as well as sugar-sweetened beverages, were linked to higher all-cause mortality. Dairy products and refined grains did not show clear associations with mortality, whereas there was a tendency in all-cause mortality for high intakes of added sugars and eggs.

Dark green vegetables include dark green leafy vegetables and broccoli. They are sources of many essential nutrients, including vitamins A, B and C, folate, fibre, carotenoids and flavonoids. This study aimed to explore the association between dietary dark green vegetable intake and cognitive function in US older adults. We included 2344 older adults (≥60 years old) from the National Health and Nutrition Examination Survey (NHANES) 2011-2014 cycles. Dark green vegetable consumption was assessed using a continuous variable (cups/day) and two categorical variables. The first categorical variable classified participants into non-consumers and consumers based on whether they consumed dark green vegetables. The second categorical variable grouped participants into four levels of dark green vegetable consumption (non-consumers, consumers with low intakes, consumers with moderate intakes and consumers with high intakes). We used five continuous variables with non-normal distribution to assess cognitive function, including a composite z-score and the standardised scores of four individual cognitive tests. The four cognitive tests included the Immediate Recall Test (IRT), the Delayed Recall Test (DRT), the Animal Mobility Test (AFT) and the Digit Symbol Substitution Test (DSST). The standardised scores of the four cognitive tests were calculated using the mean and standard deviation of each cognitive test score. The composite z-score was calculated by averaging the standardised scores of four cognitive tests to evaluate global cognition. We used multiple linear regression models to examine the association between dietary dark green vegetable intake and cognitive function. Our findings indicated that dark green vegetable intake was positively associated with global cognition (β [95% CI]: 0.17 [0.04, 0.30]; p = 0.016) and IRT (β [95% CI]: 0.26 [0.08, 0.43]; p = 0.009) and DRT (β [95% CI]: 0.21 [0.05, 0.36]; p = 0.012) standardised scores. Individuals with high intake of dark green vegetables showed notably better global cognition (β [95% CI]: 0.16 [0.05, 0.28]; p = 0.010) and showed higher IRT (β [95% CI]: 0.22 [0.07, 0.38]; p = 0.010) and DRT standardised scores (β [95% CI]: 0.21 [0.07, 0.36]; p = 0.007) compared with the non-consumers. Blood neutrophil counts mediated the cognitive benefits of dark green vegetables (Proportion: 9.5%, p = 0.006). In conclusion, our findings suggest that dark green vegetable consumption may have favourable effects on cognitive function in US older adults, especially on immediate and delayed learning abilities. The underlying mechanisms include the ability of dark green vegetables to reduce blood neutrophil levels, an indicator of decreased systemic inflammation. Increasing dietary intake of dark green vegetables may be a beneficial intervention to improve cognitive health in the older US population.

Type 2 diabetes mellitus (T2DM) is a chronic metabolic disorder that significantly increases the risk of cardiovascular disease, which is the leading cause of morbidity and mortality among diabetic patients. A central pathophysiological mechanism linking T2DM to cardiovascular complications is oxidative stress, defined as an imbalance between reactive oxygen species (ROS) production and the body's antioxidant defenses. Hyperglycemia in T2DM promotes oxidative stress through various pathways, including the formation of advanced glycation end products, the activation of protein kinase C, mitochondrial dysfunction, and the polyol pathway. These processes enhance ROS generation, leading to endothelial dysfunction, vascular inflammation, and the exacerbation of cardiovascular damage. Additionally, oxidative stress disrupts nitric oxide signaling, impairing vasodilation and promoting vasoconstriction, which contributes to vascular complications. This review explores the molecular mechanisms by which oxidative stress contributes to the pathogenesis of cardiovascular disease in T2DM. It also examines the potential of lifestyle modifications, such as dietary changes and physical activity, in reducing oxidative stress and mitigating cardiovascular risks in this high-risk population. Understanding these mechanisms is critical for developing targeted therapeutic strategies to improve cardiovascular outcomes in diabetic patients.

Noncommunicable diseases, particularly cardiovascular disease (CVD), represent a significant global public health challenge, with unhealthy diets as a major risk factor. This study investigates the association between adherence to the Planetary Health Diet proposed by the EAT-Lancet Commission and CVD risk.

Utilizing data from the Seguimiento Universidad de Navarra (SUN) cohort, which included 18,656 participants (mean age 38 years; 61% women), we assessed dietary intake using a validated food frequency questionnaire and the Planetary Health Diet Index to evaluate adherence (range 0-42). CVD was defined as new-onset stroke, myocardial infarction, or CVD death.

After a median follow-up time of 11.5 years, 220 cases of CVD were identified. Higher adherence to the Planetary Health Diet revealed no statistically significant reduction in CVD risk associated with the diet. Cox proportional hazard models indicated a trend towards lower CVD risk in the highest adherence quartile, but this did not reach significance (HR 0.77, 95% CI 0.51-1.18, p-trend = 0.127). Sensitivity analyses corroborated these results. Discrepancies in previous studies highlight the complexity of dietary assessments and underscore the need for standardized scoring systems.

In a large Spanish cohort, adherence to the Planetary Health Diet showed no significant reduction in CVD risk. Further research is needed to reach a consensus on the operational definition of the Planetary Health Diet and to clarify the relationship between diet and CVD risk.

Plant-based diets have been found to be associated with hypertension. Dietary intake is a dynamic and changing process that can be better characterized by trajectories of dietary indices. However, the associations between plant-based diet trajectories and hypertension over time remained unknown.

We used data from the China Health and Nutrition Survey 2004-2015 to analyze a cohort of Chinese adults ≥ 18 years of age who had no hypertension at baseline. Plant-based diets were measured by an overall plant-based diet index (PDI), healthful plant-based diet index (hPDI), and unhealthful plant-based diet index (uPDI) based on three 24-hour recalls. Trajectories of PDI, hPDI, and uPDI (2004 to 2011) were identified using group-based trajectory modeling. The associations between trajectories of PDIs and the risk of new-onset hypertension were estimated using Cox proportional hazard models.

We identified three trajectories for PDI, two for hPDI, and four for uPDI among the 2853 participants with a mean follow-up of 9.6 years. Compared with the PDI "low and stable" class, the PDI "high and decreasing" class had a 23% decreased risk (HR: 0.77; 95% CI: 0.62-0.95) of hypertension. There was no significant association with PDI "low and increasing" class. Compared with the hPDI "low and stable" class, the hPDI "high and stable" class had a 24% decreased risk (HR: 0.76; 95%CI: 0.64-0.91). For uPDI trajectories, compared with the "low and decreasing" class, the "high and increasing," "high and stable," and "low and increasing" classes had increased risks of 43% (HR: 1.43; 95% CI: 1.06-1.94), 77% (HR: 1.77; 95% CI: 1.26-2.49), and 72% (HR: 1.72; 95% CI: 1.26-2.33), respectively.

This study underscores the importance of maintaining high intakes of healthful plant-based diets and low intakes of unhealthful plant-based diets overtime for hypertension prevention.

Plant polyphenols are bioactive compounds touted for their antioxidant effects, and this is often the primary attribute used to explain their health benefits. However, we hypothesize that polyphenols have molecular properties independent of antioxidant function. The objective of this study was to investigate whether polyphenols had distinct molecular effects compared to pure antioxidants. RAW 264.7 macrophages were pretreated with either TEMPOL, a superoxide scavenger, N-acetyl cysteine, a hydroxyl radical and hydrogen peroxide scavenger, or polyphenol extracts from blackberry, blueberry, raspberry, strawberry, kale, and baru nut. After 1 hour of pretreatment, cells were treated with lipopolysaccharides (100 ng/mL) for an additional 6 hour. Antioxidants and polyphenol extracts elicited antioxidant effects in vitro; however, polyphenols regulated redox proteins in a distinct, protective manner, whereas antioxidants, TEMPOL, and N-acetyl cysteine, did not. Additionally, distinct effects were observed in downstream Toll-like receptor 4 signaling and transcriptional activity of inflammatory proteins. We conclude that polyphenols have unique molecular effects that are independent of just their free radical scavenging capacity. This work advances our molecular understanding of how polyphenols act to target inflammation.

The large-scale cultivation of sugar beets generates a significant amount of by-products, particularly leaves, which are often overlooked and wasted. However, these by-products are a valuable source of functional compounds that can be repurposed to enhance crop sustainability and produce food ingredients. Therefore, valorization of sugar beet leaves (SBLs) is a prudent biorefinery approach for future utilization. This literature review highlights the significant advances in valorizing SBLs for food industry applications. The extractable phytochemical compounds, the sustainability and challenges of recovery, the extraction methods, potential health benefits, current applications, and prospective valorization possibilities of SBLs within a circular economy framework were reviewed. The results showed that SBLs are rich in nutrients and bioactive phytochemicals such as polyphenols (e.g., flavonoids and phenolic acids), proteins, essential amino acids, chlorophylls, fiber, and essential fatty acids. The application of these compounds in the development of food products may exhibit numerous health benefits, including antioxidant, anti-microbial, anti-inflammatory, anti-diabetic, and anti-cancer properties. However, for potential applications of SBLs in the food industry to develop functional foods, nutritional supplements, and natural food additives, further research is needed to optimize the efficient extraction of functional compounds on an industrial scale and to verify the safety of extracted compounds for human consumption.

In the context of population aging, activities of daily living (ADL) disability has brought great challenges to the health of the elderly. The relationship between plant-based dietary patterns and the health of the elderly has been widely discussed. However, few studies have explored the correlation between plant-based dietary patterns and ADL disability in older adults.

We included 2004 participants from the Chinese Longitudinal Health Longevity Survey (CLHLS). The Simplified Food Frequency Questionnaire was used to measure Plant-Based Diet Index (PDI), healthy Plant-Based Diet Index (hPDI), and unhealthy Plant-Based Diet Index (uPDI). A Cox proportional hazards model was used to assess associations between plant-based dietary patterns and ADL disability in older adults and to explore age differences in these associations.

uPDI and hPDI showed nonlinear associations with ADL disability. Following covariate adjustments, older adults in the highest tertile of the hPDI have a lower risk of ADL disability than those in the lowest tertile (HR = 0.61). Older adults in the highest tertile of the uPDI have a higher risk of ADL disability than those in the lowest tertile (HR = 1.33). Subgroup analyses showed that hPDI was more protective against ADL disability in those under 80 years of age, whereas uPDI was only significantly associated with an increased risk of ADL disability in those under 80 years of age.

Increasing the intake of healthy plant-based diets and reducing the intake of unhealthy plant-based and animal-based diets can help prevent and improve ADL disability in the elderly.

A systematic analysis was conducted to determine the relationship between a plant-based diet and all-cause mortality.

The PubMed, Embase and Web of Science databases were searched. Two authors selected English documents from the database. Then the other two authors extracted the data and evaluated the Newcastle-Ottawa Scale (NOS). This study adhered to the guidelines of the Preferred Reporting Project (PRISMA) and the PROSPERO Registry protocols. A mixed-effects model combined maximum adjusted estimates, with heterogeneity measured using the I2 statistic. The sensitivity analysis validated the analysis's robustness, while publication bias was assessed.

The results of the meta-analysis of 14 articles revealed that a plant-based diet (PDI) can reduce cancer mortality (RR = 0.88, [95% CI 0.79-0.98], τ2: 0.02, I2: 84.71%), cardiovascular disease (CVD) mortality (RR = 0.81, [95% CI 0.76-0.86], τ2: 0.00, I2: 49.25%) and mortality (RR = 0.84, [95% CI 0.79-0.89], τ2: 0.01, I2: 81.99%) risk. Adherence to a healthy plant-based diet (hPDI) was negatively correlated with cancer mortality (RR = 0.91, [95% CI 0.83-0.99], τ2:0.01, I2:85.61%), CVD mortality (RR = 0.85, [95% CI 0.77-0.94], τ2: 0.02, I2: 85.13%) and mortality (RR = 0.85, [95% CI 0.80-0.90], τ2: 0.01, I2: 89.83%). An unhealthy plant-based diet (uPDI) was positively correlated with CVD mortality (RR = 1.19, [95% CI 1.07-1.32], τ2: 0.02, I2: 80.03%) and mortality (RR = 1.18, [95% CI 1.09-1.27], τ2: 0.01, I2: 89.97%) and had a certain correlation with cancer mortality (RR = 1.10, [95% CI 0.97-1.26], τ2: 0.03, I2: 93.11%). Sensitivity analysis showed no contradictory results.

The hPDI was negatively associated with all-cause mortality, and the uPDI was positively associated with all-cause mortality.

Although national food guides are designed, ostensibly, to translate scientific evidence with respect to food, dietary patterns, and health, their development has increasingly become a corporate/political process as well as scientific one; often with corporate/political influences overriding science. Our aim was to construct an unbiased, sustainable, evidence-informed Universal Food Guide to serve as a template for countries to develop their unique guides, thereby, provide a valid resource for health professionals, health authorities, and the public.

To address our aim, we conducted an integrative review of multiple evidence-informed sources (e.g., established databases, evidence syntheses, scholarly treatises, and policy documents) related to four areas: 1. Food guides' utility and conflicts of interest; 2. The evidence-based healthiest diet; 3. Constituents of the Universal Food Guide template; and 4. Implications for population health; regulation/governance; environment/climate/planetary health; and ethics.

The eating pattern that is healthiest for humans (i.e., most natural, and associated with maximal health across the life cycle; reduced non-communicable disease (NCD) risk; and minimal end-of-life illness) is whole food, low fat, plant-based, especially vegan, with the absence of ultra-processed food. Disparities in national food guide recommendations can be explained by factors other than science, specifically, corporate/political interests reflected in heavily government-subsidized, animal-sourced products; and trends toward dominance of daily consumption of processed/ultra-processed foods. Both trends have well-documented adverse consequences, i.e., NCDs and endangered environmental/planetary health. Commitment to an evidence-informed plant-based eating pattern, particularly vegan, will reduce risks/manifestations of NCDs; inform healthy food and nutrition policy regulation/governance; support sustainable environment/climate and planetary health; and is ethical with respect to 'best' evidence-based practice, and human and animal welfare.

The Universal Food Guide that serves as a template for national food guides is both urgent and timely given the well-documented health-harming influences that corporate stakeholders/politicians and advisory committees with conflicts of interest, exert on national food guides. Such influence contributes to the largely-preventable NCDs and environmental issues. Policy makers, health professionals, and the public need unbiased, scientific evidence as informed by the Universal Food Guide, to inform their recommendations and choices.

The "One Health" approach underscores the connection between human, animal, and environmental health, promoting solutions to global challenges like climate change and biodiversity loss. The Planetary Health Diet (PHD) promotes a plant-based diet with organically grown plants to reduce the environmental impact of meat production and decrease the risk of non-communicable diseases (NCDs). The BIOQUALIM project will evaluate the PHD's effectiveness in preventing NCDs like periodontal diseases and cancers through four inter-related studies.

The clinical study will involve volunteers reducing their meat consumption and incorporating einkorn into their diet, allow for analysis of their interdental microbiota, oral health, general health, and quality of life. The chemical analysis will study nutrients and anti-cancer compounds in einkorn and common wheat varieties. The behavioral study will explore PHD knowledge, attitudes, and behaviors related to PHD. The psycho-social study will evaluate the impact of peer-support workshops on plant-based dietary cooking among post-therapy cancer patients.

The results are expected to demonstrate that einkorn varieties possess nutritional properties that, when incorporated into the PHD enriched with einkorn, can enhance health markers. This study will identify barriers to and facilitators of PHD adoption and highlight how peer-support workshops can improve dietary adherence.

BIOQUALIM's transdisciplinary approach will demonstrate the PHD's role in preventing NCDs.

Cardiovascular disease (CVD) is a prominent contributor to morbidity and mortality, particularly in the middle-aged and elderly population. Plant-based, high-fiber diets high in fruits, vegetables, whole grains, legumes, and nuts can significantly lower CVD risk factors. This systematic review aims to assess how effectively diet improves cardiovascular health in this demographic. Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) criteria, we thoroughly searched PubMed, Google Scholar, ScienceDirect, Cochrane Library, and ClinicalTrials.gov, explicitly focusing on papers published in English. The review identified 10 pertinent papers, including three systematic reviews, one randomized-controlled trial (RCT), two observational studies, and four review articles demonstrating significant improvements in blood pressure, cholesterol levels, and glycemic management associated with high-fiber plant-based diets (PBDs). The research specifically emphasized the significance of dietary fiber in decreasing low-density lipoprotein (LDL) cholesterol, enhancing insulin sensitivity, and reducing systemic inflammation. These data support the concept that PBDs high in fiber can effectively lower CVD risk factors. However, limitations such as self-reported dietary intake and variability in adherence were noted. In conclusion, high-fiber PBDs are a viable strategy for managing and preventing CVD in middle-aged and older adults. Future research should focus on long-term adherence, the comparative benefits of different plant-based foods, and developing personalized dietary recommendations to optimize cardiovascular health outcomes in this population.

Thrombosis of retinal veins is one of the most common retinal vascular diseases that may lead to vascular blindness. The latest epidemiological data leave no illusions that the burden on the healthcare system, as impacted by patients with this diagnosis, will increase worldwide. This obliges scientists to search for new therapeutic and diagnostic options. In the 21st century, there has been tremendous progress in retinal imaging techniques, which has facilitated a better understanding of the mechanisms related to the development of retinal vein occlusion (RVO) and its complications, and consequently has enabled the introduction of new treatment methods. Moreover, artificial intelligence (AI) is likely to assist in selecting the best treatment option for patients in the near future. The aim of this comprehensive review is to re-evaluate the old but still relevant data on the RVO and confront them with new studies. The paper will provide a detailed overview of diagnosis, current treatment, prevention, and future therapeutic possibilities regarding RVO, as well as clarifying the mechanism of macular edema in this disease entity.

Plant-based diets (PBDs) are gaining attention as a sustainable and health-conscious alternative for managing various chronic conditions, including metabolic dysfunction-associated steatotic liver disease (MASLD). In the absence of pharmacological treatments, exploring the potential of lifestyle modifications to improve biochemical and pathological outcomes becomes crucial. The adoption of PBDs has demonstrated beneficial effects such as weight control, increased metabolic health and improved coexisting diseases. Nonetheless, challenges persist, including adherence difficulties, ensuring nutritional adequacy, and addressing potential deficiencies. The aim of this review is to provide a comprehensive overview of the impact of PBDs on MASLD, emphasizing the need for tailored dietary interventions with professional support to optimize their effectiveness in preventing and treating metabolic diseases.

Cardiovascular diseases (CVDs) are characterized by abnormalities in the heart, blood vessels, and blood flow. CVDs comprise a diverse set of health issues. There are several types of CVDs like stroke, endothelial dysfunction, thrombosis, atherosclerosis, plaque instability and heart failure. Identification of a new drug for heart disease takes longer duration and its safety efficacy test takes even longer duration of research and approval. This chapter explores drug repurposing, nano-therapy, and plant-based treatments for managing CVDs from existing drugs which saves time and safety issues with testing new drugs. Existing drugs like statins, ACE inhibitor, warfarin, beta blockers, aspirin and metformin have been found to be useful in treating cardiac disease. For better drug delivery, nano therapy is opening new avenues for cardiac research by targeting interleukin (IL), TNF and other proteins by proteome interactome analysis. Nanoparticles enable precise delivery to atherosclerotic plaques, inflammation areas, and damaged cardiac tissues. Advancements in nano therapeutic agents, such as drug-eluting stents and drug-loaded nanoparticles are transforming CVDs management. Plant-based treatments, containing phytochemicals from Botanical sources, have potential cardiovascular benefits. These phytochemicals can mitigate risk factors associated with CVDs. The integration of these strategies opens new avenues for personalized, effective, and minimally invasive cardiovascular care. Altogether, traditional drugs, phytochemicals along with nanoparticles can revolutionize the future cardiac health care by identifying their signaling pathway, mechanism and interactome analysis.

"The Seven Countries Study", published in 1984, was the first study to find a correlation between diet and mortality related to cardiovascular diseases (CVDs). Since then, many investigations have addressed the relationship between type of diet, or specific nutrients, and CVDs. Based on these findings, some traditional dietary models, such as the Mediterranean or Nordic diet, are recommended to prevent CVDs. Meanwhile, new diets have been proposed for optimal nutrition therapy, for example, the Dietary Approaches to Stop Hypertension (DASH) and the Mediterranean-DASH Intervention Diet for Neurodegenerative Delay (MIND). The main outcomes evaluated after implementing these dietary models are as follows: CVD-related death; the development of specific CVDs, such as myocardial infarction and hypertension; or biochemical parameters related to CVDs, i.e., non-HDL cholesterol, C-reactive protein (CPR) and homocysteine. However, the early impact of diet on heart functionality is less evaluated. Recently, the echographic measurement of left ventricle (LV) deformation by global longitudinal strain (GLS) has been introduced as a novel marker of clinical and subclinical cardiac dysfunction. This technology allows a subclinical evaluation of heart functionality since, differently from the traditional evaluation of left ventricle ejection fraction (LVEF), it is capable of detecting early myocardial dysfunction. In this review, we analyzed the available studies that correlate dietetic regimens to cardiovascular diseases, focusing on the relevance of LV strain to detect subclinical myocardial alteration related to diet. Evidence is presented that DASH and MIND can have a positive impact on heart functionality and that myocardial strain is useful for early detection of diet-related changes in cardiac function.

Obstructive sleep apnoea (OSA) and obesity commonly coexist. Weight loss and exercise are recommended management options for OSA. However, most of the current evidence on diet and OSA is focused on calorie restriction rather than diet quality. The aim of the present study was to determine the association of plant-based dietary indices (PDI) with OSA risk.

Cross-sectional data from 14 210 participants of the National Health and Nutrition Examination Survey who provided dietary information using the 24-hour recall method were used. PDI - including healthy (hPDI), unhealthy (uPDI) and pro-vegetarian diet index (PVDI) - were determined. OSA risk was determined using the STOP-BANG questionnaire. Logistic regression was used to determine the relationship between dietary indices and OSA risk.

Higher adherence to PDI (odds ratio (OR)Q5 versus Q1=0.81; 95% confidence interval (CI): 0.66-1.00), hPDI (OR=0.83; 95% CI: 0.69-1.01) and PVDI (OR=0.84; 95% CI: 0.68-1.05) was inversely associated with OSA risk, whereas higher consumption of an unhealthy plant-based diet (OR=1.22; 95% CI: 1.00-1.49) was positively associated with OSA. Sex differences in estimates were observed for PDI in males (OR=0.71; 95% CI: 0.56-0.90) versus females (OR=0.93; 95% CI: 0.68-1.28), hPDI in males (OR=0.90; 95% CI: 0.68-1.18) versus females (OR=0.77; 95% CI: 0.54-1.09) and uPDI in males (OR=1.13; 95% CI: 0.89-1.44) versus females (OR=1.42; 95% CI: 1.03-1.97) but not for PVDI.

Higher adherence to a healthy plant-based diet is associated with reduced OSA risk, while an unhealthy plant-based diet has a positive association. The magnitude of these associations differs by sex. Further longitudinal studies are warranted.

Substituting plant protein for animal protein has emerged as a promising strategy for managing atherogenic lipids. However, the impact of long-term intake of a high plant protein diet (HPD) on hepatic lipid disorder remains unclear.

Eight-week-old apolipoprotein E deficient (apoE-/- ) mice are fed with either a normal protein diet (NCD) or HPD for 12 weeks. HPD intervention results in decreased body weight accompanied by increased energy expenditure, with no significant effect on glycemic control. Long-term intake of HPD improves the serum and hepatic lipid and cholesterol accumulation by suppressing hepatic squalene epoxidase (SQLE) expression, a key enzyme in cholesterol biosynthesis. Integrated analysis of 16S rDNA sequencing and metabolomics profiling reveals that HPD intervention increases the abundance of the Lachnospiraece family and serum levels of 12,13-DiHOME. Furthermore, in vivo studies demonstrate that 12,13-DiHOME significantly inhibits lipid accumulation, as well as SQLE expression induced by oleic acid in HepG2 cells.

Diet rich in plant protein diet alleviates hyperlipidemia via increased microbial production of 12,13-DiHOME.

The positive effects of the Mediterranean diet on healthy living are widely known, while the health effects of religious fasting have received increased attention during the last decade. However, no study has focused on the consumption of ultra-processed foods (UPFs) in such populations. Therefore, our aim was to investigate UPF intake and its association with metabolic syndrome (MetS) in a Christian Orthodox church (COC) religious fasting population in Greece. In this cross-sectional study, 400 individuals who follow the Mediterranean diet were included, stratified as COC fasters and non-fasters. Dietary intake data were collected via three 24 h diet recalls and a monthly food frequency questionnaire (FFQ). The NOVA food classification system was used to identify the level of processing and categorize all food items. Fasters consumed significantly less chicken, turkey, and beef and significantly more seafood, fish, snails, soy products, and fresh fruits, in terms of unprocessed or minimally processed foods, as well as significantly more fried potatoes and olives in terms of processed foods when compared with non-fasters. Regarding UPFs, a significantly lower intake of pork sausages, ketchup, and mustard as well as a significantly higher consumption of margarine and tarama dip were recorded in fasters compared with non-fasters. Fasters with MetS more frequently consumed UPFs (such as cheese pastries, biscuits, and cakes) than fasters without MetS (p < 0.05 for all comparisons). Similarly, non-fasters with MetS had an increased intake of UPFs (such as Cypriot bread and Coco Pops breakfast cereals) than non-fasters without MetS. Future research should focus on UPF consumption and its associations with clinical outcomes in such populations, thus providing further data for the potential health effects of COC fasting.

Alzheimer's disease (AD) is a progressive neurodegenerative disease, characterized by memory loss and multiple cognitive impairments. Genetic mutations cause a small proportion (1-2%) of early-onset AD, with mutations in amyloid precursor protein (APP), presenilin 1 (PS1) and presenilin 2 (PS2). Major contributing factors of late-onset AD are ApoE4 genotype, traumatic brain injury, diabetes, obesity, hypertension, cardiovascular conditions, in addition to lifestyle factors, such as unhealthy diet and lack of physical exercise. Disease progression can be delayed and/or prevented to a greater extent by adopting healthy lifestyle with balanced and antioxidant enriched diet and daily exercise. The interaction and interplay of diet, exercise, age, and pharmacological interventions holds a crucial role in the progression, pathogenesis and management of AD and its comorbidities, including diabetes, obesity, hypertension and cardiovascular conditions. Antioxidant enriched diet contributes to brain health, glucose control, weight management, and cardiovascular well-being. Regular exercise removes toxins including free radicals and enhances insulin sensitivity, and supports cardiovascular function. In the current article, we discussed, the role of diet, and exercise in aging, AD and other conditions including diabetes, obesity, hypertension, cardiovascular conditions. This article also highlights the impact of medication, socioeconomic and lifestyle factors, and pharmacological interventions. These aspects were discussed in different races and ethnic groups in Texas, and the US.

Coronary artery disease (CAD), a primary component of cardiovascular diseases, is one of the top contributors to mortality rates worldwide. In 2021, dietary risk was estimated to be attributed to 6.58 million cardiovascular deaths. Plant-based diets (PBDs), which encourage higher consumption of plant foods and lower intake of animal-based foods, have been shown to reduce the risk of CAD by up to 29% when compared to non-vegetarian diets in a meta-analysis. This article aims to summarize the array of PBDs and compare them with conventional Western diets that include meat. We review the various proposed mechanisms for how the bioactive nutrients of PBDs aid in preventing atherosclerosis and CAD events, as well as other cardiac diseases. We conducted a detailed search of PubMed using our exclusive search strategy using the keywords plant-based diet, vegan diet, phytosterols, CAD, myocardial ischemia, and atherosclerosis. A total of 162 pertinent articles published within the past decade were identified for qualitative synthesis. To ensure the accuracy and reliability of our review, we included a total of 55 full-text, peer-reviewed articles that demonstrated the effects of plant-based diets on CAD and were written in English. We excluded animal studies, in vitro or molecular studies, and non-original data like editorials, letters, protocols, and conference abstracts. In this article, we emphasize the importance of dietary interventions, such as PBDs, to prevent CAD and their benefits on environmental sustainability. Integrating plant foods and whole grains into one's daily eating habits leads to an increase in the intake of nutrient-rich foods while reducing the consumption of processed food could not only prevent millions of premature deaths but also provide prevention against many chronic gastrointestinal and metabolic diseases.

The Western diet is a modern dietary pattern characterized by high intakes of pre-packaged foods, refined grains, red meat, processed meat, high-sugar drinks, candy, sweets, fried foods, conventionally raised animal products, high-fat dairy products, and high-fructose products. The present review aims to describe the effect of the Western pattern diet on the metabolism, inflammation, and antioxidant status; the impact on gut microbiota and mitochondrial fitness; the effect of on cardiovascular health, mental health, and cancer; and the sanitary cost of the Western diet. To achieve this goal, a consensus critical review was conducted using primary sources, such as scientific articles, and secondary sources, including bibliographic indexes, databases, and web pages. Scopus, Embase, Science Direct, Sports Discuss, ResearchGate, and the Web of Science were used to complete the assignment. MeSH-compliant keywords such "Western diet", "inflammation", "metabolic health", "metabolic fitness", "heart disease", "cancer", "oxidative stress", "mental health", and "metabolism" were used. The following exclusion criteria were applied: (i) studies with inappropriate or irrelevant topics, not germane to the review's primary focus; (ii) Ph.D. dissertations, proceedings of conferences, and unpublished studies. This information will allow for a better comprehension of this nutritional behavior and its effect on an individual's metabolism and health, as well as the impact on national sanitary systems. Finally, practical applications derived from this information are made.

With the increasing adoption of plant-based diets in the United States, more and more individuals replace cow milk with plant-based milk alternatives. Soy milk is a commonly used cow milk substitute, which is characterized by a higher content of polyunsaturated fatty acids and fibers. Despite these favorable characteristics, little is known about the current prevalence of soy milk consumption the United States. We used data from the National Health and Nutrition Examination Surveys (NHANES) to assess soy milk usage in the United States and identified potential predictors for its consumption in the US general population. The proportion of individuals reporting soy milk consumption in the NHANES 2015-2016 cycle was 2%, and 1.54% in the NHANES 2017-2020 cycle. Non-Hispanic Asian and Black ethnicities (as well as other Hispanic and Mexican American ethnicities in the 2017-2020 cycle) significantly increased the odds for soy milk consumption. While a college degree and weekly moderate physical activity were associated with significantly higher odds for consuming soy milk (OR: 2.21 and 2.36, respectively), sex was not an important predictor. In light of the putative health benefits of soy milk and its more favorable environmental impact as compared to cow milk, future investigations should attempt to identify strategies that may help promote its consumption in selected populations.
