One Month Whole Food Plant-Based Nutrition Educational Program Lowers LDL, A1C, and Decreases Inflammatory Markers.

Lifestyle-related chronic disease increases in the United States have led to the need for innovative programs targeting dietary choices. Based on growing evidence supporting whole food plant-based (WFPB) nutrition to improve overall health, we devised a one-month WFPB intervention program, Jumpstart Your Health! (JYH), to introduce and encourage adoption of the WFPB dietary lifestyle. This paper investigates its effects on various health indicators associated with cardiovascular and metabolic diseases. Among the total of 150 participants, before and after physical measurements and blood chemistries demonstrate significant (p< 0.05) decreases in weight (-4.2 pounds), cholesterol (-25.3mg/dl), LDL (-19.0mg/dl), HDL (-5.6mg/dl), hemoglobin A1c (-0.2%), and hsCRP (-1.9mg/L). Among the high-risk participants, we found significant decreases in systolic blood pressure (-10mmHg), diastolic blood pressure (-8.7mmHg), weight (-4.3pounds), cholesterol (-38.8mg/dl), LDL (-22.7mg/dl), HDL (-2.8mg/dl), hemoglobin A1c (-0.2 %), and hsCRP (-2.3mg/L). We demonstrate that a simple WFPB intervention implemented over one month resulted in significant reductions in physical measurements and blood chemistries that could translate to lowered risk or improvement for obesity, cardiovascular disease, and type-2 diabetes.

A Qualitative Study of Rural Plant-Based Eaters' Knowledge and Practices for Nutritional Adequacy.

(1) Background: Healthful plant-based diets, especially those rich in minimally processed plant-based foods such as fruits, vegetables, and whole grains, have been associated with a lower risk of diet-related chronic disease. However, individuals who limit or avoid animal products may be at risk of nutrient deficiencies, especially related to Vitamin B12, Vitamin D, omega-3 fatty acids, calcium, iron, iodine, zinc, and protein. Such deficiencies can result in both short- and long-term health challenges. We used qualitative methods to explore plant-based eaters' knowledge and awareness of these eight nutrients of concern in diets that limit or exclude animal-source foods. (2) Methods: We conducted interviews with 28 rural flexitarian, pescatarian, vegan, or vegetarian adults in Vermont, USA. (3) Results: The participants positively viewed the healthfulness of plant-based diets, but many recognized limitations to accessing Vitamin B12, Vitamin D, and omega-3 fatty acids. They shared the strategies used to meet their needs including eating a varied diet, seeking out specific foods, and taking dietary supplements. Analyses identified gaps in the participants' knowledge related to nutrient bioavailability, food sources of specific nutrients, and the importance of zinc and iodine. Vegans-the highest-risk group-generally presented as the most knowledgeable. The participants noted a lack of local plant-based nutrition expertise. (4) Conclusions: Addressing the identified knowledge gaps and challenges to dietary adequacy, especially among those who limit, but do not fully omit, animal-source foods, may support plant-based nutrition.

Research to Radicchio: Process Implementation of a Therapeutic Whole Food Plant-Based (WFPB) Inpatient Menu Within a Large Academic Healthcare System

Evidence on the benefits of consuming a whole food, plant-based (WFPB) dietary pattern for overall health and chronic disease prevention and remission is mounting. A large amount of evidence supports plant-predominant nutrition with significant con- tributions to the research coming from the Adventist Health Studies (AHS) at Loma Linda University Health (LLUH). The totality of evidence on plant-predominant nutrition has influenced guideline changes by the American College of Cardiology and the American Medical Association to strongly recommend hospitals offer plant-based nutrition to patients. A knowledge translation project was spearheaded at LLUH to adopt evidence-based research into acute care while also meeting emerging guidelines and regulations. A therapeutic inpatient menu comprised of whole plant foods with no added oils or refined sugars and low in sodium for the purpose of adjunct treatment of acute illness management was developed. Multidisciplinary team development, key stakeholder involvement, and applying effective strategies to overcome challenges were crucial in implementing system-wide changes to align the best nutritional evidence with clinical practice.

Dementia and Cognitive Decline: A HEALM Approach.

Dementia and cognitive decline pose significant global public health challenges, with prevalence expected to rise in the coming decades. Lifestyle medicine offers a promising approach to mitigating cognitive issues through six key interventions: diet, physical activity, restorative sleep, social connections, stress management, and avoiding risky substances. Traditional methods like randomized controlled trials (RCTs) have limitations in capturing the long-term impacts of these interventions. To overcome these challenges, the American College of Lifestyle Medicine (ACLM) and the True Health Initiative (THI) developed the Hierarchies of Evidence Applied to Lifestyle Medicine (HEALM) framework, informed by the Evidence Threshold Pathway Mapping (ETPM) approach. This framework integrates diverse evidence sources to assess intervention effects over time. Applying HEALM, this review evaluates lifestyle factors' impact on dementia and cognitive decline. It finds strong evidence supporting plant-based nutrition, physical activity, restorative sleep, and avoiding risky substances in promoting cognitive health. Social connections may mitigate cognitive decline, while stress management requires further investigation due to inconclusive findings. Integrating these findings into public health strategies could effectively address the growing dementia burden and enhance overall well-being in aging populations, underscoring the need for continued research in cognitive health.

Nutrition and fasting

Patients with rheumatic diseases often enquire about the options for nutritional therapy. Nutritional factors have been empirically described that are associated with the occurrence of inflammatory rheumatic diseases or flare-ups or improved disease states. Agrowing number of epidemiological and clinical studies deal with the evaluation of nutrition and dietary restriction in rheumatology. Narrative presentation of the evidence of nutritional interventions and fasting and its clinical implications. Only limited data from smaller clinical studies are available for evidence assessment. Abenefit in terms of symptoms and quality of life in rheumatoid arthritis was shown for the Mediterranean and plant-based diet as well as the anti-inflammatory diet. The effect sizes are small to moderate and the effectiveness in the context of complex lifestyle programs is probably sustainable. The evidence for elimination diets is weak. Initial clinical studies indicate amoderate benefit of plant-based nutrition for osteoarthritis in the context of the metabolic syndrome. There is moderate evidence for the benefit of dietary weight normalization in psoriasis. There is clear experimental evidence of asignificant anti-inflammatory effect of prolonged fasting. Several clinical studies demonstrated asymptomatic benefit of prolonged modified fasting (therapeutic fasting) in rheumatoid arthritis (RA). If fasting is followed by avegan and vegetarian diet, lasting effects of up to 1year have been documented. Cardiometabolic but not antirheumatic effects have been proven for intermittent fasting. Nutrition and fasting can be classified as apossible useful addition to conventional treatment but are currently only rarely taken into account in practice.

An Innovative Program for Hospital Nutrition.

New York City (NYC) Health + Hospitals implemented a nutrition program making plant-based meals the primary lunch and dinner options for patients at its 11 hospitals. Plant-based and culturally diverse meals are prepared and distributed by a central culinary center, managed by Sodexo. Food service associates visit patient rooms and verbally introduce the featured meals each day. To ensure alignment among all staff members, staff are educated about the health benefits of plant-based nutrition and about the new menu items. The plant-based meals have been well received, with patient acceptance over 95% and patient satisfaction above 90%. Per-tray food costs for plant-based entrees cost $0.59 less compared to trays including animal products. Furthermore, the hospital system has achieved a 36% reduction in calculated carbon emissions as a result of the new plant-based menu. Because dietary choices contribute significantly to health and may influence the likelihood of hospital readmissions, prioritizing plant-based meals and nutrition education during the hospital stay may help improve patient outcomes.

From Garden to Pillow: Understanding the Relationship between Plant-Based Nutrition and Quality of Sleep.

The effect of diet on sleep quality has been addressed in many studies; however, whether/how plant-based diets (PBDs) impact sleep-related parameters has not been explored in detail. This review aims to give an overview of the components of PBDs and the possible mechanisms through which PBDs may improve sleep quality. Studies have indicated that diets such as PBDs, which are typically high in fruits, vegetables, nuts, seeds, whole grains, and fiber, are associated with better sleep outcomes, including less fragmented sleep and improved sleep duration. Several mechanisms may explain how PBDs impact and/or improve sleep outcomes. Firstly, PBDs are characteristically rich in certain nutrients, such as magnesium and vitamin B6, which have been associated with improved sleep patterns. Secondly, PBDs are often lower in saturated fats and higher in fiber, which may contribute to better overall health, including sleep quality. Additionally, plant bioactive compounds like phytochemicals and antioxidants in fruits, vegetables, and herbs may have sleep-promoting effects. According to available data, PBD and Mediterranean diet elements promise to enhance sleep quality; however, it is crucial to note that diets should be customized based on each person's needs.

Progress in physiologically based pharmacokinetic-pharmacodynamic models of amino acids in humans.

Amino acids are critical to health, serving both as constituents of proteins and in signaling and metabolism. Amino acids are consumed as nutrients, supplements, and nutraceuticals. Much remains to be learned about amino acid function. Physiologically based pharmacokinetic and pharmacodynamic (PBPK-PD) modeling is an emerging tool for studying their complex biology. This review highlights recent PBPK-PD models developed to study amino acid physiology and metabolism and discusses their potential for addressing unresolved questions in the field. PBPK-PD models provided several insights. They revealed the interplay between the mechanisms by which leucine governs skeletal muscle protein metabolism in healthy adults. The models also identified optimal dosing regimens of amino acid supplementation to treat sickle-cell disease and recurrent hypoglycemia, and to minimize drug side effects in seizure disorders. Additionally, they characterized the effects of novel anticancer drugs that seek to deprive cancer cells of amino acids. Future models may inform treatment strategies for sarcopenia, characterize distinctions between animal- and plant-based nutrition, and inform nutrient-drug interactions in Parkinson's disease. PBPK-PD models are powerful tools for studying amino acid physiology and metabolism, with applications to nutrition, pharmacology, and their interplay.

Gut Microbiota as Therapeutic Targets in Diabetes Management: Opportunities and Challenges

This article delves into the complex interplay between Type 2 Diabetes Mellitus (T2DM), gut microbiota, and dietary strategies for effective diabetes management. T2DM, characterized by insulin resistance and β-cell dysfunction, is influenced by genetic and environmental factors. The gut-brain axis and alterations in incretin functioning contribute to gastrointestinal permeability in T2DM. Plant-based diets offer substantial benefits for managing T2DM by improving emotional well-being, HbA1c levels, weight, and cholesterol. High-fiber diets positively impact gut microbiota, serum metabolism, and emotional health in T2DM individuals. Probiotics, prebiotics, synbiotics, and postbiotics (PPSP) are emerging as pivotal interventions. Probiotics improve serum fructosamine, HbA1c, and cholesterol levels, while prebiotics like oligofructose-enriched inulin and synbiotics enhance glycemic control and lipid profiles. Insights from microbiome studies in diverse dietary populations provide personalized approaches for diabetes management. Integrating plant-based nutrition, PPSP interventions, and microbiome-focused strategies may offer a comprehensive and effective approach to T2DM management, addressing physiological aspects and empowering individuals in their health journey.

Domestic dogs maintain clinical, nutritional, and hematological health outcomes when fed a commercial plant-based diet for a year.

Domestic dogs can maintain health on complete and well-balanced canine plant-based nutrition (K9PBN). Novel insight on health outcomes in dogs consuming K9PBN is of relevance to veterinary professionals and consumers given a growing interest in non-traditional dog foods with perceived health benefits, while considering potential safety concerns. We aimed to investigate nutritional equivalence by measuring clinical health outcomes in adult dogs fed K9PBN over twelve months compared to a meat-based diet at baseline. We enrolled fifteen clinically healthy adult dogs living in households in Los Angeles County, California in a prospective cohort study and evaluated clinical, hematological, and nutritional parameters in dogs at 0, 6, and 12 months, including complete blood count (CBC), blood chemistry, cardiac biomarkers, plasma amino acids, and serum vitamin concentrations. The study found that clinically healthy, client-owned, adult dogs maintain health, based on physical exams, complete blood count, serum chemistry, plasma amino acids, serum vitamins, and cardiac biomarkers combined with client-reported observations, when fed commercial K9PBN over a twelve-month period. This study is the most comprehensive and longest known K9PBN investigation to date and provides clinically relevant evidence-based nutrition data and new knowledge on outcomes in clinically healthy dogs who thrive without consumption of animal-derived ingredients. These results also provide a valuable foundation for the future study of K9PBN as a potential nutritional intervention for clinically relevant pathologies in canine medicine. Lastly, it is of major relevance to One Health paradigms since ingredients produced independent of industrial food animal production are both more sustainable and help to circumvent ethical dilemmas for maintenance of health in domestic dogs.

This study pioneers further research in the food, pharmaceutical, and cosmetic industries to contribute to sustainable water resource utilization.

Planting the Seed for Blood Pressure Control: The Role of Plant-Based Nutrition in the Management of Hypertension.

Hypertension results in significant morbidity, mortality, and healthcare expenditures. Fortunately, it is largely preventable and treatable by implementing dietary interventions, though these remain underutilized. Here, we aim to explore the role of healthy dietary patterns in hypertension management and describe approaches for busy clinicians to address nutrition effectively and efficiently with patients. DASH, Mediterranean, vegetarian, and vegan diets that include minimally processed, plant-based foods as core elements have consistently shown positive effects on hypertension. Recommendations that distill the most healthful components of these diets can significantly impact patient outcomes. Clinicians can harness evidence-based dietary assessment and counseling tools to implement and support behavioral changes, even during brief office visits. Healthful plant-based dietary patterns can often effectively prevent and treat hypertension. Clinicians may help improve patient outcomes by discussing evidence-based nutrition with their patients. Future work to promote infrastructural change that supports incorporating evidence-based nutrition into medical education, clinical care, and society at large can support these efforts.

ObjectiveThis study describes program implementation through a research-restaurant partnership and assesses participant satisfaction, program costs, and percent body weight changes. MethodsParticipants (n = 60) in a virtual synchronous (n = 43) or virtual asynchronous (n = 17) 12-week plant-based nutrition program received restaurant vouchers. Class satisfaction data were collected weekly. Assessments were completed at baseline, 3 months, and 9 months, along with interviews (n = 13) between 3 and 9 months. The costing approach estimated costs per participant. Interviews were coded using a content analysis and constant comparative method. ResultsParticipants rated the intervention favorably. Program costs were $198.63/participant, and participants’ willingness to pay postintervention was $101.50 ± $63.90. Participants shared satisfaction with course content, the restaurant partnership, and suggestions for future delivery. No changes in participants’ percent body weight were observed between 3 and 9 months (P = 0.98), indicating maintenance of 3-month weight loss. Conclusions and ImplicationsA research-restaurant partnership successfully implemented a nutrition program and generated positive feedback. With the lifting of coronavirus disease 2019 pandemic restrictions, future research can now test alternative implementation methods (in person vs online) in other restaurants.

Editorial: nutrition at key stages of the lifecycle.

Nutritional requirements of individuals vary across the lifecycle, according to activity, age and gender. To optimize human health, consideration of nutritional priorities at each stage is needed. This conference brought together multidisciplinary experts in maternal and child nutrition and health, cardiometabolic and plant-based nutrition and dietitians involved in the care of vulnerable populations, plus nutritional metabolism, health and ageing. The presentations highlighted the most important nutrition research in these areas, updating knowledge and suggesting how dietary advice and policy could be adapted to incorporate research findings. With the global increase in non-communicable disease (NCD) and nutrition being considered as a key modifiable risk factor for the prevention and management of NCD, this conference was much needed.

The Role of Natural Extracts in the Management of Infantile Hemangiomas and Vascular Tumors.

Hemangiomas are vascular tumors resulting from the proliferation of endothelial-like cells; they are the most common childhood tumors, affecting approximately 5-10% of newborns and infants. Besides hemangiomas, which are definitely benign tumors despite their overgrowth potential, there are other vascular tumors like hemangioendotheliomas, which may display intermediate characteristics between benign hemangiomas and highly malignant angiosarcomas. Standard therapy may be constricted by serious adverse effects, high cost, or traumatic influence. Diet is a major resource for health preservation, disease prevention, and treatment. The therapeutic property of edible berries, marine products, or medicinal plants have long been known and used in traditional medicine; a plant-based nutrition can prevent the development and progression of diseases associated with extensive neo-vascularization. The purpose of our review is to highlight those natural treatments that hemangioma and vascular tumor patients can receive in the future, both for their benefit and that of their families. We performed the review according to the Preferred Reporting Items for Systematic Reviews and Metanalysis Statement. We used the Web of Science, PubMed, and EMBASE engines for the study, and searched for the association of hemangioma with naturopathic treatment/plant extract/plants in published articles. We found that natural extracts from plants and fruits are cost-effective and safe treatments for hemangiomas and vascular tumors, as well as for other forms of cancer. In any case, more in vitro and in vivo studies are needed to confirm the proposed signaling pathways in tumors and validate the improvement parameters after natural products administration. The era of molecularly targeted therapy and personalized medicine is approaching and naturally occurring substances are very useful tools for tumor treatment and prevention. Plant extract substances have strong specificity and pertinence, are non- toxic and have few side effects, and may become an emerging cancer treatment.

Knowledge, attitude and practices of health professionals with regard to plant-based diets in pregnancy: a scoping review.

This scoping review aimed to systematically map and describe the existing evidence regarding the knowledge, attitudes and practices of health professionals with regard to plant-based diets during pregnancy and to highlight areas for further research. Following a pre-registered protocol, online databases were searched using a comprehensive search string, in addition to selected grey literature sources, and reference lists of included studies. The studies were independently screened for eligibility by two authors, SM and JM. Data from all eligible studies were charted by the first author, and a narrative summary was performed. Maternal health care services. Ten studies were included for review, from New Zealand (n 2), Australia (n 2), Germany, Netherlands, United Kingdom, France, Italy and Peru. Most of these studies were observational, employed various validated and non-validated survey instruments, interviews and one education intervention. Knowledge was the most frequently assessed outcome in the reviewed studies. Health professionals' knowledge of plant-based nutrition in pregnancy was reported to be limited and frequently attributed to a lack of nutrition training. Participants' personal dietary patterns and work specialisation appear to be closely associated with their knowledge, attitudes and practices regarding plant-based diets. This review identified a significant research gap regarding health professionals' practices in relation to plant-based diets during pregnancy. Additionally, this review has demonstrated the need for further research, awareness and practice protocols to promote high-quality care and education or professional development to address the prevalent lack of knowledge among this group.

Development of a plant-based culinary nutrition model for sports science students

Introduction: Food and fitness levels are key factors required to maintain functional life. Hence, nutrition education is crucial in spreading awareness among Sports Science students. There is a paucity of plant-based nutrition knowledge and plantbased culinary skills for fitness locally. Therefore, this study aimed to develop a valid Plant-Based Culinary Nutrition Model (PBCNM) with nutrition knowledge and basic culinary skills to improve fitness among Sports Science students. Methods: This exploratory sequential mixed method study consisted of 2 phases. In Phase 1, a three-round modified Delphi method was conducted with 13 experts to generate a questionnaire that was validated. Lawshe worksheet determined the content validity ratio (CVR) for an item. Content validity index (CVI) for each section and the overall instrument was calculated. In Phase 2, quantitative data collection and analysis addressed the research questions and research gaps leading to model development. A total of 271 undergraduate Sports Science students at higher learning institutions were recruited as respondents. Results: In Phase 1, CVR of the overall survey was 1.0 and CVI was 0.834. Subsequently, the questionnaire was pilot tested for reliability and a Cronbach’s alpha score of 0.836 was obtained for the overall questionnaire. In Phase 2, the respondents’ mean and standard deviation score for the model’s components and needs was 4.21±0.73 for items 1-15. The integration of experts’ perspectives on the need of PBCNM for fitness and feedback from respondents resulted in the development of PBCNM. Conclusion: This study highlighted PBCNM as a helpful guideline for better fitness management.
