Social Support, Diet, and Physical Activity among Latina/Hispanic Women Breast Cancer Survivors.

Diet and physical activity guidelines for cancer survivorship are less likely to be followed by populations of minority cancer survivors, such as Latina/Hispanic women, compared to non-Hispanic White women. It is important to understand psychosocial mechanisms that may increase adherence to healthy lifestyle habits, especially in populations at risk for poorer cancer outcomes. This cross-sectional study examined the relationships between overall social support (SS) and SS from three sources (family, friends, and significant other) with diet (fruit and vegetables, fat, energy density, and diet quality), and moderate-to-vigorous physical activity (MVPA) behaviors in Latina/Hispanic women with a history of breast cancer (n = 85; M age = 55.2; SD = 9.2). Linear regression models and odds ratios were used to examine associations and adjusted for age, income, and acculturation. Family, significant other, and total SS were positively related to total fruit and vegetable intake but SS from friends was not. Higher levels of SS from all sources were each related to a low energy density diet. A higher quality diet was only related to SS from family. SS was not related to fat intake or MVPA. Higher SS from family and a significant other were associated with higher odds of meeting the fruit/vegetable guidelines; (family, OR = 3.72, 95% CI [1.21, 11.39]; significant other, OR = 3.32, 95% CI [1.08, 10.30]). Having more SS from family or a significant other may contribute to Latina/Hispanic women breast cancer survivors meeting national guidelines for a diet high in fruits and vegetables and low in energy density.

Blended diet in enteral feeding: current guidance.

The practice of administering blended food via enteral feeding tubes has been growing in popularity in recent years. Concerns have been raised as this practice was perceived to increase risk of gastrointestinal intolerance, allergic reactions, nutritional insufficiency, tube blockages, and infection compared with using commercial enteral feed (CEF), the gold standard, as well as risk of litigation against the professional due to their support of practice that is not evidence-based. However, research has shown that the physical, social and emotional benefits from receiving blended diet may outweigh the previously suggested risks. Guidance has been updated to encourage discussions around blended diet while informing the tube-fed individuals, families and carers of potential risks, potential benefits, barriers, considerations for training, safety and contraindications.

Adherence to Mediterranean Diet and Health Outcomes in Adolescents: An Umbrella Review.

CONTEXT: Proper nutrition represents 1 of the domains of adolescents' well-being. In this context, the Mediterranean diet (MD), as a healthy, traditional, and sustainable dietary pattern, plays a crucial role in promoting adequate growth and preventing chronic noncommunicable diseases. OBJECTIVE: The currently available evidence on the effects of adherence to the MD (AMD) in association with several physical health outcomes in adolescence is summarized in this review. DATA SOURCES: Five electronic databases were searched. STUDY SELECTION: Systematic reviews with or without meta-analysis of observational studies and randomized clinical trials, published in English during 2013-2022, and that assessed the health impact of AMD among adolescents were eligible. DATA EXTRACTION: Details on study design, methods, population, assessment of dietary patterns, health outcomes, and main results were extracted. RESULTS: The search yielded 59 references after removal of duplicates. Applying PICOS criteria, 4 systematic reviews and 3 meta-analyses ultimately were included in this review. The AMD was evaluated in association with overweight/obesity and adiposity in 2 studies, musculoskeletal health in another 2, inflammation in 1 study, and cardiometabolic health in 1 study. The seventh review examined all mentioned health outcomes (overweight and obesity, musculoskeletal health, inflammation, and cardiometabolic health) in relation to AMD. CONCLUSIONS: Overall, this umbrella review showed limited evidence and a lack of consistency about the relation between AMD and health outcomes of interest in adolescence, indicating the need for more studies to better understand it. SYSTEMIC REVIEW REGISTRATION: PROSPERO registration no. CRD42023428712.

Conducting a successful diet trial for the diagnosis of food allergy in dogs and cats.

A limited antigen diet trial and subsequent food provocation is currently the optimal method of confirming a diagnosis of food allergy in dogs and cats. However, performing an effective diet trial can be challenging as it requires a high level of client and pet compliance, appropriate diet selection and correct interpretation of the provocative challenge. This narrative guides the clinician through the process, highlights potential pitfalls and specifies how these can be avoided to achieve a successful outcome.

Dietary plasticity and broad North Atlantic origins inferred from bulk and amino acid-specific δ15N and δ13C favour killer whale range expansions into Arctic waters.

Killer whales (Orcinus orca) occur seasonally in the eastern Canadian Arctic (ECA), where their range expansion associated with declining sea ice have raised questions about the impacts of increasing killer whale predation pressure on Arctic-endemic prey. We assessed diet and distribution of ECA killer whales using bulk and compound-specific stable isotope analysis (CSIA) of amino acids (AA) of 54 skin biopsies collected from 2009 to 2020 around Baffin Island, Canada. Bulk ECA killer whale skin δ15N and δ13C values did not overlap with potential Arctic prey after adjustment for trophic discrimination, and instead reflected foraging history in the North Atlantic prior to their arrival in the ECA. Adjusted killer whale stable isotope (SI) values primarily overlapped with several species of North Atlantic baleen whales or tuna. Amino acid (AA)-specific δ15N values indicated the ECA killer whales fed primarily on marine mammals, having similar glutamic acid δ15N-phenylalanine δ15N (δ15NGlx-Phe) and threonine δ15N (δ15NThr) as mammal-eating killer whales from the eastern North Pacific (ENP) that served as a comparative framework. However, one ECA whale grouped with the fish-eating ENP ecotype based δ15NThr. Distinctive essential AA δ13C of ECA killer whale groups, along with bulk SI similarity to killer whales from different regions of the North Atlantic, indicates different populations converge in Arctic waters from a broad source area. Generalist diet and long-distance dispersal capacity favour range expansions, and integration of these insights will be critical for assessing ecological impacts of increasing killer whale predation pressure on Arctic-endemic species.

The Effect of a Vegan Diet on the Health Indicators and Outcomes of P atients with Type 2 Diabetes Mellitus.

INTRODUCTION/OBJECTIVES: Recently, there has been a notable increase in interest in various forms of vegetarianism, which may be due to the growing prevalence of health issues, such as Type 2 Diabetes Mellitus (T2DM). Adhering to a vegan diet may have positive health outcomes. As a result, we conducted a review article to gather data from previous research studies on the effects of a vegan diet on different aspects of managing patients with T2DM. METHODS: We searched the PubMed website for research studies on how a vegan diet affects the outcomes of patients with T2DM. The research studies were categorized according to the type of data collected, such as prevalence, incidence, body weight, insulin resistance, glycemic control, and lipid profile. RESULTS: It was found that following a vegetarian diet can significantly reduce the risk of mortality from heart disease. Additionally, studies have demonstrated that a vegetarian diet is linked to several improvements in T2DM. However, long-term weight loss plans and managing T2DM is a comprehensive intervention that includes caloric restriction, exercise, and behavioral modification. CONCLUSION: Incorporating a vegan diet can be a valuable factor to consider in managing T2DM, as it can offer numerous benefits, such as increased insulin sensitivity, weight loss, and reduced blood sugar levels. It helps to reduce cholesterol levels, LDL, and triglyceride levels, which are all risk factors associated with T2DM. By reducing these risk factors, the vegan diet can improve the overall health of T2DM patients.

Promoting musculoskeletal health and preventing ill health.

Musculoskeletal conditions are highly prevalent among older adults and can have a significant impact on their quality of life. Musculoskeletal health is an important component of maintaining well-being and independence. A proactive approach is required, with nurses implementing strategies such as healthy diets and physical exercise that will support optimal health. This article considers the importance of musculoskeletal health, examines the risk factors for a decline in musculoskeletal health, and explores approaches that can improve outcomes and promote healthy ageing.

The Role of Exercise: Physical Fitness Changes Caused by Hypocaloric Diet and Exercise in Men Who Are Overweight.

OBJECTIVE: There is evidence showing the effect of hypocaloric diet and increasing physical activity on weight loss. However, the effect of these factors on body composition and functional capacity remains unclear. Also, it is not clear which type of exercise (aerobic, resistance) has effective health benefits for men who are overweight. The aim of this study is to investigate whether a 12-week combined exercise or walking intervention combined with a hypocaloric diet provides improvements in body composition and functional capacity of men who are overweight compared to those who do not exercise. METHODS: 60 healthy adult men who are overweight were randomized and divided into 3 groups: 1: Hypocaloric Diet + Combined Exercise; 2: Hypocaloric Diet + Walking; 3: Hypocaloric Diet. The exercise groups were trained for 12 wk, 3 days a week and 60 min (60 min\3 days\12 wk). Body composition was determined with Bioelectrical Impedance Analysis (BIA) device, strength parameters with MicroFet 2, functional capacity with 6-min walking test. RESULTS: Improvement was observed in all groups at the end of 12 wk. The greatest improvement was in the combined exercise group. While the values of the combined exercise group increased in Skeletal Muscle Mass, there was a decline in the walking and non-exercising group. Basal Metabolism was maintained in combined exercise, but a decrease occurred in the non-exercising group. Muscle force increased in combined exercise; however, it was maintained in the legs in the walking group. Cardiorespiratory fitness was at best level in walking group, but there was no difference between combined exercise. CONCLUSIONS: As a result, a hypocaloric diet without an exercise prescription is sufficient to lose weight in the short term (12 wk) at a certain level. But exercise is more important for body composition, weight management and functional capacity. Long-term and in-depth studies should be conducted to interpret the results better.

Long-Term High-Fat Diet Impairs AQP4-Mediated Glymphatic Clearance of Amyloid Beta.

As a risk factor for Alzheimer's disease (AD), studies have demonstrated that long-term high-fat diet (HFD) could accelerate the deposition of amyloid beta (Aß) in the brain. The glymphatic system plays a critical role in Aß clearance from the brain. However, studies investigating the effects of long-term HFD on glymphatic function have reported paradoxical outcomes, and whether glymphatic dysfunction is involved in the disturbance of Aß clearance in long-term HFD-fed mice has not been determined. In the present study, we injected fluorescently labeled Aß into the hippocampus and found that Aß clearance was decreased in HFD-fed mice. We found that long-term HFD-fed mice had decreased glymphatic function by injecting fluorescent tracers into the cisterna magna and corpus striatum. In long-term HFD-fed mice, aquaporin-4 (AQP4) polarization in the cortex was disrupted, and glymphatic clearance activity was positively correlated with the AQP4 polarization index. In HFD-fed mice, the disturbance of Aß clearance from the hippocampus was exacerbated by TGN-020, a specific inhibitor of AQP4, whereas TGN-073, an enhancer of AQP4, ameliorated it. These findings suggest that long-term HFD disrupts Aß clearance by inhibiting AQP4-mediated glymphatic function. The underlying mechanism may involve the disruption of AQP4 polarization.

Evaluation of bone marrow glucose uptake and adiposity in male rats after diet and exercise interventions.

Objectives: Obesity impairs bone marrow (BM) glucose metabolism. Adult BM constitutes mostly of adipocytes that respond to changes in energy metabolism by modulating their morphology and number. Here we evaluated whether diet or exercise intervention could improve the high-fat diet (HFD) associated impairment in BM glucose uptake (BMGU) and whether this associates with the morphology of BM adipocytes (BMAds) in rats. Methods: Eight-week-old male Sprague-Dawley rats were fed ad libitum either HFD or chow diet for 24 weeks. Additionally after 12 weeks, HFD-fed rats switched either to chow diet, voluntary intermittent running exercise, or both for another 12 weeks. BMAd morphology was assessed by perilipin-1 immunofluorescence staining in formalin-fixed paraffin-embedded tibial sections. Insulin-stimulated sternal and humeral BMGU were measured using [18F]FDG-PET/CT. Tibial microarchitecture and mineral density were measured with microCT. Results: HFD rats had significantly higher whole-body fat percentage compared to the chow group (17% vs 13%, respectively; p = 0.004) and larger median size of BMAds in the proximal tibia (815 µm2 vs 592 µm2, respectively; p = 0.03) but not in the distal tibia. Switch to chow diet combined with running exercise normalized whole-body fat percentage (p < 0.001) but not the BMAd size. At 32 weeks of age, there was no significant difference in insulin-stimulated BMGU between the study groups. However, BMGU was significantly higher in sternum compared to humerus (p < 0.001) and higher in 8-week-old compared to 32-week-old rats (p < 0.001). BMAd size in proximal tibia correlated positively with whole-body fat percentage (r = 0.48, p = 0.005) and negatively with humeral BMGU (r = -0.63, p = 0.02). HFD significantly reduced trabecular number (p < 0.001) compared to the chow group. Switch to chow diet reversed this as the trabecular number was significantly higher (p = 0.008) than in the HFD group. Conclusion: In this study we showed that insulin-stimulated BMGU is age- and site-dependent. BMGU was not affected by the study interventions. HFD increased whole-body fat percentage and the size of BMAds in proximal tibia. Switching from HFD to a chow diet and running exercise improved glucose homeostasis and normalized the HFD-induced increase in body fat but not the hypertrophy of BMAds.

Effect of quality and quantity of diet on nutritional status of under-five children residing in the rural area: A longitudinal study.

Introduction: Variety and adequacy of intake of food are required to meet the nutritional needs of the children. Due to poverty/illiteracy, poor families depend on a single food group that is, cereals. Due to the pandemic also, the nutrition of the growing children is affected. Objective: To know the effect of quantity and quality of diet on the nutritional status of under-five children. Methodology: This study had 270 children aged between 1 and 4 years registered at Anganwadi as study participants. Information on sociodemographic variables, quantity of calories and proteins consumed, quality of diet, and anthropometry of children was collected. Percentages and paired t-tests were used to find the difference between nutritional status and diet at different intervals, which was found to be statistically significant (P < 0.05). Results: In our study, we found that as the quantity and quality of diet improved nutritional status, especially weight for age, body mass index (BMI) for age Z score also improved. There was a significant difference between calories consumed at the baseline, 6 months and 1 year with P < 0.05. Protein intake was significant between baseline and six months with P < 0.005. Conclusion: Our study found a high percentage of undernutrition and wasting in the under-five population when diet was not sufficient in quality and quantity. As the quality and quantity of diet improved nutritional status also improved.

Impact of high-salt diet in health and diseases and its role in pursuit of cancer immunotherapy by modulating gut microbiome.

Cancer chemotherapy remains an area of concern, as many of the therapies are uncomfortable involving side effects and unpleasant experiences. These factors could further reduce patient's quality of life, and even endanger their life. Many therapeutic strategies have been tried to reduce the unpleasant side effects and increase the treatment effectiveness; however, none have shown to have promising effects. One of the main hindrances to cancer therapy is the escape strategies by tumor cells to the immune attack. Promoting inflammation in the tumor microenvironment is the cornerstone and key therapeutic target in cancer chemotherapy. High-salt diet (HSD) intake, though it has deleterious effects on human health by promoting chronic inflammation, is found to be advantageous in the tumor microenvironment. Studies identified HSD favors an increased abundance of Bifidobacterium species in the tumor environment due to gut barrier alteration, which, in turn, promotes inflammation and favors improved response to cancer chemotherapy. A review of the literature was carried out to find out the effects of an HSD on health and diseases, with special mention of its effect on cancer chemotherapy. Studies emphasized HSD would block the myeloid-derived suppressor cells which will enhance the tumor immunity. Exploration of the precise mechanism of simple HSD regime/ingestion of specific bacterial species as probiotics will be effective and essential to formulate the game-changing cancer chemotherapy. With the modern era of healthcare moving toward precision medicine where the physician can choose the treatment option suitable for the individual, HSD regime/ingestion of specific bacterial species can be considered.

Medical students' dietary habits: Motivations and barriers to reaching health goals.

Introduction: It has been well reported that medical students do not follow healthy diets overall. Effectively guiding patients to change their health behavior is a crucial skill for primary care providers and family physicians. Our objective was to investigate medical students' dietary decision-making, including the motivations and barriers that influence their dietary choices. Methods: A self-administered online questionnaire was conducted among preclinical students at one allopathic medical school in the United States. The survey was comprised of questions about students' dietary goals, habits, and the barriers they face in reaching their nutritional ideals. Trends in the percentage of students who selected each survey answer choice were interpreted. Results: Of the 363 preclinical students provided with the optional survey, 71 (19.6%) chose to participate. The participants' dietary decisions were predominately driven by convenience. Most students wanted to eat nutritiously to support their well-being but had been eating less healthily since starting medical school due to financial limitations and limited time. Approximately half (46.5%, 33/71) of the participants stated that they would buy the in-house food provided at the medical school campus more often if it better matched their dietary goals, but 36.6% (26/71) would only do so if the new foods were affordable compared to competitor's prices. Conclusion: There is an opportunity to help medical students meet their dietary goals, which are negatively impacted by personal and structural academic barriers. Further research is needed on the obstacles that institutions face in offering healthy, affordable options to medical students.

A study to assess the effect of yoga and diet on Framingham risk score among high-risk cardiovascular subjects.

Introduction: Cardiovascular diseases (CVDs) are a cluster of disorders of blood vessels and the heart. As a form of physical activity, yoga postures, and pranayama have been shown to be beneficial in various health conditions, i.e. hypertension, prediabetes, and diabetes among high-risk subjects. This study aimed to evaluate the impact of yoga and diet on the Framingham risk score (FRS) among high-risk cardiovascular subjects. Materials and Methods: The experimental interventional study was conducted at "RUHS College of Medical Sciences" and Associated Group of Hospitals", Jaipur among high-risk cardiovascular subjects. FRS was used as a measurement for the outcome of interest at baseline and six months of yoga diet intervention in the study and control groups. Results: Mean age of participants was 48.43 ± 6.4 years. Baseline values (mean ± SD) of FRS 24.59 ± 10.15 after six months of yogic lifestyle 15.1 ± 7.05. After six months of yogic lifestyle FRS scores and estimated 10-year cardiovascular risk were statistically significantly (P < 0.0001) decreased. Pearson correlation analysis results depict that FRS correlation. There was a strong positive correlation between the FRS score and total cholesterol (r = 0.787; P < 0.001) and a negative strong correlation between the FRS score and high-density lipoprotein was observed (r =-0.621; P < 0.002). Conclusion: The findings of this study conclude that six months of yoga and diet lifestyle intervention significantly decreased FRS among high-risk CVD subjects compared to the control group.

Adiponectin in spinal cord injury: What is the role of nutrition in serum adiponectin concentration?

Objectives: The study aimed to analyze the relationship between serum adiponectin concentration, Mediterranean diet (MD) adherence, and Dietary Approaches to Stop Hypertension (DASH) diet adherence in patients with spinal cord injury (SCI). Patients and methods: Thirty-three SCI patients (21 males, 12 females; median age: 33 years; range, 18 to 65 years) and 33 age-, sex-, and body mass index-matched healthy controls (21 males, 12 females; median age: 33 years; range, 18 to 64 years) were included in this cross-sectional study between March 2021 and March 2022. Serum adiponectin concentrations of all participants were measured. Body weight, height, and neck, hip, waist, and mid-upper arm circumferences were measured. Twenty-four-hour dietary records were obtained by the researchers for evaluation of the nutritional status. The DASH diet score and MD score were measured for each participant. Results: Most of the cases of SCI were due to motor vehicle collisions (n=12, 36.4%) and complete paraplegic. Mid-upper arm circumference, waist circumference, hip circumference, and neck circumference of the patient group were significantly higher than the control group (p=0.020, p=0.002, p=0.042, and p<0.001, respectively). Mediterranean diet scores and DASH diet scores of the patient group were significantly higher than the control group (p<0.001 and p=0.031, respectively). Serum adiponectin concentration of patients was significantly higher than the control group (p=0.049). No correlation was detected between adiponectin concentration, MD score, and DASH diet score in both groups. Conclusion: Although correlation analysis in the current research did not show significant relation between nutrition and adiponectin concentrations, nutrition of patients with SCI, as demonstrated by higher adherence to MD and DASH, may have provided positive effects on adiponectin concentrations. Future studies focused on the effect of a healthy diet intervention on serum adiponectin concentration is warranted.

A Clustering Study of Sociodemographic Data, Dietary Patterns, and Gut Microbiota in Healthy and Breast Cancer Women Participating in the MICROMA Study.

SCOPE: This work is part of the clinical study NCT03885648 registered in ClinicalTrials.gov, aimed at studying the relationship among breast cancer, microbiota, and exposure to environmental pollutants. As a first step, we characterized and evaluated risk factors of the participants. METHODS AND RESULTS: A case-control study was designed with breast cancer (cases, n = 122) and healthy women (controls, n = 56) recruited in two hospitals of Andalusia (Southern Spain). Participants answered questionnaires of Mediterranean diet adherence and food frequency. Data were collected from medical histories and microbiota was analyzed on stool samples. Most cases (78.2%) were diagnosed as stages I and II. Cases had higher age, body mass index (BMI), glucose, cholesterol, and potassium values than controls. Cases exhibited higher adherence to the Mediterranean diet and their food consumption was closer to that dietary pattern. A hierarchical cluster analysis revealed that the Bacillota/Bacteroidota ratio was the most relevant variable in women with breast cancer, which was higher in this group compared with controls. CONCLUSION: Although cases exhibited higher adherence to the Mediterranean diet compared with controls, they presented features and microbiota alterations typical of the metabolic syndrome, probably due to their higher BMI and reflecting changes in their lifestyle around the time of diagnosis.

Microbial tryptophan catabolism as an actionable target via diet-microbiome interactions.

In recent years, the role of microbial tryptophan (Trp) catabolism in host-microbiota crosstalk has become a major area of scientific interest. Microbiota-derived Trp catabolites positively contribute to intestinal and systemic homeostasis by acting as ligands of aryl hydrocarbon receptor and pregnane X receptor, and as signaling molecules in microbial communities. Accumulating evidence suggests that microbial Trp catabolism could be therapeutic targets in treating human diseases. A number of bacteria and metabolic pathways have been identified to be responsible for the conversion of Trp in the intestine. Interestingly, many Trp-degrading bacteria can benefit from the supplementation of specific dietary fibers and polyphenols, which in turn increase the microbial production of beneficial Trp catabolites. Thus, this review aims to highlight the emerging role of diets and food components, i.e., food matrix, fiber, and polyphenol, in modulating the microbial catabolism of Trp and discuss the opportunities for potential therapeutic interventions via specifically designed diets targeting the Trp-microbiome axis.

Clinical presentation of celiac disease in adult patients: current real-life experience.

BACKGROUND AND AIMS: The clinical presentation of celiac disease (CD) has changed over time with more patients presenting with non-classical symptoms, extra-intestinal manifestations (EIM) or no symptoms. We aimed to investigate the main symptoms/signs leading to the diagnosis of CD in adult patients. As secondary end-point, we evaluated the outcome of gastrointestinal (GI) symptoms following gluten-free diet (GFD). METHODS: All consecutive CD adult patients referring to our University Hospital from September 2022 to February 2024 were included. Clinical data were retrospectively evaluated. RESULTS: 134 patients, 104 females/30 males, median age at diagnosis 35 years, were included. 79 patients reported GI symptoms (i.e., diarrhea, abdominal bloating, dyspepsia) as the main symptom leading to CD diagnosis. In 40 patients, the leading symptom/sign was an EIM (i.e., iron deficiency anemia, infertility/miscarriages, dermatitis, osteoporosis, elevated transaminase levels). Fifteen patients were asymptomatic, being diagnosed because of a positive family history or concomitant autoimmune hypothyroidism. Of the 79 patients reporting GI symptoms, 20 did not experience complete resolution with the GFD. Among the 17 patients who reported a strict adherence to GFD (vs 1 patient with low-adherence, 2 non-compliant), lactose intolerance and irritable bowel syndrome overlap were diagnosed in 2 and 15 patients, respectively. CONCLUSION: GI manifestations remain the main symptoms at presentation of CD, however clinicians should be aware of the EIM of CD and the association with other autoimmune disorders. In non-responsive CD patients, an overlap with functional disorders might be considered.

The LIDPAD Mouse Model Captures the Multisystem Interactions and Extrahepatic Complications in MASLD.

Metabolic dysfunction-associated steatotic liver disease (MASLD) represents an impending global health challenge. Current management strategies often face setbacks, emphasizing the need for preclinical models that faithfully mimic the human disease and its comorbidities. The liver disease progression aggravation diet (LIDPAD), a diet-induced murine model, extensively characterized under thermoneutral conditions and refined diets is introduced to ensure reproducibility and minimize species differences. LIDPAD recapitulates key phenotypic, genetic, and metabolic hallmarks of human MASLD, including multiorgan communications, and disease progression within 4 to 16 weeks. These findings reveal gut-liver dysregulation as an early event and compensatory pancreatic islet hyperplasia, underscoring the gut-pancreas axis in MASLD pathogenesis. A robust computational pipeline is also detailed for transcriptomic-guided disease staging, validated against multiple harmonized human hepatic transcriptomic datasets, thereby enabling comparative studies between human and mouse models. This approach underscores the remarkable similarity of the LIDPAD model to human MASLD. The LIDPAD model fidelity to human MASLD is further confirmed by its responsiveness to dietary interventions, with improvements in metabolic profiles, liver histopathology, hepatic transcriptomes, and gut microbial diversity. These results, alongside the closely aligned changing disease-associated molecular signatures between the human MASLD and LIDPAD model, affirm the model's relevance and potential for driving therapeutic development.
