RESUMO

Multiple sclerosis (MS) is a chronic autoimmune demyelinating disease of the central nervous system, the etiology of which is still unclear. Its hallmarks are inflammation and axonal damage. As a disease primarily impacting younger individuals, the social cost of MS is high. It has been proposed that environmental factors, smoking, and dietary habits acting on a genetic susceptibility play a role in MS. Recent studies indicate that diet can significantly influence the onset and progression of MS. This review delves into the impact of natural bioactive molecules on MS development and explores the dietary interventions that hold promise in managing the disease. Dietary patterns, including ketogenic and Mediterranean diets, are discussed. Theories about the potential mechanistic associations beneath the noted effects are also proposed. Several dietary components and patterns demonstrated the potential for a significant impact on MS. However, extensive prospective clinical trials are necessary to fully understand the role of natural bioactive molecules as disease modifiers in MS.

RESUMO

PURPOSE: Obesity can increase mortality and morbidity in breast cancer survivors. Healthy lifestyle factors such as diet can help manage weight in this population. This systematic review examined lifestyle interventions with dietary strategies for breast cancer survivors and their effect on diet and/or weight-related outcomes. METHODS: Searches were conducted in Ovid MEDLINE® ALL (1946-February 14, 2022), Embase (Elsevier), CINAHL Complete (EBSCO), and APA PsycArticles (EBSCO), using keywords for diet, breast cancer, and intervention. The search was limited to human studies, English language, and publication processing date 2016-2023. RESULTS: The search yielded 3427 articles. After title and abstract review, 225 full-text articles were screened, and 67 articles with 61 distinct samples and interventions met inclusion criteria. Of these 61 lifestyle interventions with dietary strategies, 43 interventions also addressed physical activity. Most studies were randomized controlled trials (n = 41) and conducted post-treatment (n = 45). Mean participant age was 54 years. Of 29 studies that reported race/ethnicity, 20 (69%) reported ≥50% White participants. Of 36 that reported dietary outcomes, 29 (81%) reported significant findings. Of 57 that reported weight-related outcomes, 51 (89%) reported significant findings. CONCLUSION: This review demonstrated promising evidence for the efficacy of lifestyle interventions with dietary strategies in breast cancer survivors. However, culturally tailored interventions and interventions conducted before and during treatment are lacking.

RESUMO

A key guiding principle in the 2020-2025 Dietary Guidelines for Americans emphasizes the need for individuals to choose eating habits that allows for personal, cultural, and traditional preferences while establishing a high-quality diet. This concept becomes a daunting task given the need to reduce the consumption of foods higher in saturated fat, sodium, and/or added sugar-which are typically found in familiar, highly palatable foods most-often liked and consumed in the United States. Similarly, in nutrition intervention studies, adherence to healthier dietary patterns is typically low because of many factors, including reduced taste, flavor, and familiarity to the study foods. Increasing evidence illustrates the promising role of herbs and spices to maintain acceptability of healthier food options for nutrition interventions. This perspective article was informed by a Satellite Session presented at the American Society for Nutrition's annual meeting, Nutrition 2023, entitled, "Developing Culturally Appropriate Recipes for Human Clinical Trials," which explored several proposed best practice guidelines when developing nutrition interventions to improve dietary adherence and acceptability within clinical trials. The session also highlighted a need to include sufficient detail concerning the types and amounts of specific foods included within nutrition interventions in combination with preparation methods and study recipes, including herbs and spices, to improve intervention reproducibility and translatability for future research, dietary guidelines, and clinical practice.

RESUMO

BACKGROUND: This scoping review aims to critically assess gaps in the current literature on atopic dermatitis (AD) by evaluating the overall effectiveness of dietary interventions. Through a comprehensive analysis that follows the Preferred Reporting Item for Systematic Review and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR) guidelines, we conducted a thorough search on the Web of Science database in May 2023 using specific search strategies to identify all relevant studies on the research topic. SUMMARY: A total of 104 full-text articles were included for review. Our synthesis identified seven notable categories of dietary interventions for AD, showcasing the diversity of interventions utilized. This includes vitamin supplementation, probiotic and prebiotic supplementation, dietary fat, biological compounds, foods from natural sources, major nutrients, and diet-related approaches. Further analyses stratified by targeted populations revealed a predominant focus on pediatrics, particularly in probiotic supplementation, and on adults, with an emphasis on vitamin D and E supplementation. KEY MESSAGES: Despite most dietary interventions demonstrating overall effectiveness in improving AD severity and its subjective symptoms, several significant gaps were identified. There was a scarcity of studies on adults and whole-diet interventions, a prevalence of short-term interventions, heterogeneity in study outcomes, designs, and population, occasional disparity between statistical significance and clinical relevance, and a lack of a comprehensive multidisciplinary approach. Nonetheless, these findings offer valuable insights for future AD research, guiding additional evidence-driven dietary interventions and informing healthcare professionals, researchers, and individuals, advancing both understanding and management of AD.

RESUMO

BACKGROUND AND HYPOTHESIS: Metabolic acidosis is a common complication of kidney disease and can result in further disease progression. Alkali therapy has been used to treat metabolic acidosis for decades. However, some concerns have been raised regarding its safety and long-term tolerability. Existing data suggest that dietary interventions can be beneficial in the management of chronic kidney disease (CKD). This systematic review and meta-analysis aims to summarize findings from studies comparing dietary interventions with placebo/usual care/no treatment in the management of metabolic acidosis in outpatient adults with CKD. METHODS: Medline, Embase, Cochrane Central, CINAHL, and Web of Science Core Collection were searched from inception to June 2022. Our primary outcome measure was change in serum bicarbonate. Any dietary intervention looking to manipulate dietary acid load was considered as an intervention. Data screening and extraction were performed by two independent reviewers. Random effects meta-analysis was performed to pool data. RESULTS: Dietary interventions resulted in clinically significant improvement in serum bicarbonate (mean difference (MD):2.98, 95% CI: [0.77, 5.19]; I2: 91%) and higher eGFR levels (MD: 3.16, 95%CI: [0.24, 6.08], I2: 67%) compared to controls. Serum potassium, albumin and body mass index remained unchanged. Dietary interventions were reported to be safe. Subgroup analyses indicated a superiority of plant-based over non-plant-based interventions in the improvement of acid-base balance and eGFR, however, these findings are from low quality and heterogenous studies. CONCLUSION: Our findings support the beneficial effects of dietary interventions aimed at reducing acid or adding base in the management of metabolic acidosis and kidney function in adults with CKD, with no adverse effects on serum potassium and nutritional status. Well-designed clinical trials looking at the treatment of metabolic acidosis with dietary interventions with a focus on adding base through fruit and vegetables are required.

RESUMO

By the beginning of the year 2021, the estimated number of new cancer cases worldwide was about 19.3 million and there were 10.0 million cancer-related deaths. Cancer is one of the deadliest diseases worldwide that can be attributed to genetic and environmental factors, including nutrition. The good nutrition concept focuses on the dietary requirements to sustain life. There is a substantial amount of evidence suggesting that a healthy diet can modulate cancer risk, particularly the risk of colorectal and breast cancers. Many studies have evaluated the correlation between our diet and the risk of cancer development, prevention, and treatment. The effect of diet on cancer development is likely to happen through intertwining mechanisms including inflammation and immune responses. For instance, a greater intake of red and processed meat along with low consumption of fruits and vegetables has been associated with increased levels of inflammatory biomarkers that are implicated in cancer development. On the other hand, the consumption of phytosterols, vitamins, and minerals, which exert antioxidant and anti-inflammatory roles have been linked to lower cancer risk, or even its occurrence prevention. In this book, we aim to summarize the current knowledge on the role of nutrition in cancer to provide the best scientific advice in this regard.

RESUMO

The term "cancer" refers to the state in which cells in the body develop mutations and lose control over their replication. Malignant cancerous cells invade in various other tissue sites of the body. Chemotherapy, radiation, and surgery are the first-line modalities for the majority of solid cancers. These treatments work by mitigating the DNA damage of cancerous cells, but they can also cause harm to healthy cells. These side effects might be immediate or delayed, and they can cause a high rate of morbidity and mortality. Dietary interventions have a profound impact on whole-body metabolism, including immunometabolism and oncometabolism which have been shown to reduce cancer growth, progression, and metastasis in many different solid tumor models with promising outcomes in early phase clinical studies. Dietary interventions can improve oncologic or quality-of-life outcomes for patients that are undergoing chemotherapy or radiotherapy. In this chapter, we will focus on the impact of nutritional deficiencies, several dietary interventions and their proposed mechanisms which are used as a novel therapy in controlling and managing cancers.

RESUMO

PURPOSE: This study aimed to estimate the health, economic, and environmental impacts of moderate simulated interventions on dietary intake in Brazil. METHODS: Data on food price and consumption were obtained from three nationwide surveys. Baseline dietary intake was estimated for 33,859 individuals aged 25 years and older. Counterfactual intakes were based on six hypothetical intervention scenarios, by changing the weekly frequency and serving size in low or high consumers of fruit and vegetables (FV), milk, whole grains, red and processed meats, and sugar-sweetened beverages. For each scenario, we estimated the attributable number of deaths and disability-adjusted life years (DALY), monetary cost, environmental impacts (14 midpoint indicators), and environmentally-mediated health impacts. RESULTS: Compared with the baseline intake and cost, the most expensive intervention (+ 8.3%) was to increase FV intake (+ 125 g), resulting in a 1.2% reduction in all-cause mortality (16,307 deaths/year). The cheapest (- 9.9%) was to reduce red and processed meat intake (- 40 g), resulting in a 1.1% reduction in all-cause mortality (14,272 deaths/year). The combined intervention was, on average, 3.7% cheaper than the baseline cost, resulting in an increase in diet cost for 30% of the population (45-22% in the lower- and higher-income groups); all-cause mortality would be reduced by 3.8% (49,488 deaths/year). Interventions targeting red and processed meats would reduce emissions and resource use by 35-55%, in addition to reducing 2300 DALYs/year. CONCLUSION: A meaningful number of deaths can be avoided and environmental impacts reduced through moderate and potentially affordable diet modifications.

RESUMO

BACKGROUND: Asthma is a common chronic condition with increasing prevalence. Diet, including dried fruit consumption, has been linked to asthma risk, but the mechanisms remain unclear. This study investigates how dried fruit consumption affects asthma risk, focusing on acetate as a potential mediator. METHODS: We used Mendelian Randomization (MR) to analyze the relationships between dried fruit intake, acetate levels, and asthma. We applied three MR methods-Inverse-Variance Weighted (IVW), Weighted Median (WM), and MR-Egger-to determine causal effects. RESULTS: Dried fruit intake was inversely associated with asthma risk (IVW: ß = -0.506, p = 0.0135) and positively associated with acetate levels (IVW: ß = 0.269, p < 0.0001). Higher acetate levels were also linked to lower asthma risk (IVW: ß=-0.361, p < 0.0001). Mediation analysis showed that acetate mediates approximately 19.22% of the effect of dried fruit on asthma risk. CONCLUSION: Dried fruit consumption reduces asthma risk, partly through increasing acetate levels. This acetate-mediated pathway accounts for about 20% of the effect, suggesting potential for dietary strategies in asthma prevention and management. Further research could enhance the understanding and applicability of these findings.

RESUMO

Metabolic dysfunction-associated steatotic liver disease (MASLD) is a metabolic disorder marked by excessive accumulation of lipids within the liver. If untreated, this condition can progress to metabolic dysfunction-associated steatohepatitis (MASH), fibrosis, cirrhosis, and ultimately, hepatocellular carcinoma (HCC). Given the liver's pivotal role in glucose and fatty acid metabolism, disruptions in these processes are commonly observed in MASLD. Ketone bodies, crucial energy metabolites primarily produced in the liver, are also closely related to the progression of MASLD. Recent studies have demonstrated that disrupted ketogenesis not only accompanies MASLD, but may also play a causal role in its development and progression. Moreover, activation of the ketogenic pathway has been suggested as a promising strategy for reducing excessive hepatic fat accumulation. This review focuses on the regulation of ketogenesis in MASLD, emphasizing the significance of dietary and pharmacological interventions as potential therapeutic approaches to treat fatty liver disease.

RESUMO

PURPOSE: Neuroendocrine neoplasms (NENs) represent heterogeneous tumors arising from neuroendocrine cells in different organs. Despite growing interest in the nutritional aspects of NEN management, research in this area is limited. Aim of this review is to summarize the current state of knowledge, highlight research gaps, and underscore the significance of nutrition in the comprehensive care of NEN patients. METHODS: We conducted an extensive bibliographic search focusing on studies (including retrospective and prospective studies, systematic reviews, case series, and guidelines) exploring the relationship between nutritional assessments, dietary interventions, micronutrient deficiencies, and their impact on NEN outcomes. RESULTS: Significant gaps exist in current research, particularly in understanding the specific nutritional needs of NEN patients and how tailored nutritional interventions can improve clinical outcomes. Evidence suggests that a high-fat Western diet may promote the growth of NEN, while a Mediterranean diet may help lower insulin levels and strengthen the immune system, potentially preventing tumor development. The ketogenic diet and intermittent fasting may also have positive impacts. Addressing common micronutrient deficiencies, such as vitamin D and niacin, is crucial to mitigate disease progression. There's a crucial need for future studies to include a comprehensive nutritional assessment incorporating patient-reported outcomes, to fully capture the impact of nutritional strategies. CONCLUSION: Nutritional management, an important but under-researched facet of NEN treatment, significantly improves patients' quality of life and survival. Integrating nutrition into personalized cancer care is essential, highlighting the role of nutritional strategies in optimizing patient outcomes.

RESUMO

PURPOSE OF REVIEWS: Headaches represent a prevalent and burdensome health condition, affecting individuals of all ages worldwide. While dietary factors have been implicated in headache pathophysiology, the association between dairy consumption and headaches remains controversial and inadequately understood. This comprehensive review systematically examines the existing literature to elucidate the relationship between dairy intake and headaches, addressing methodological challenges, potential biases, and gaps in the current knowledge. RECENT FINDINGS: A thorough search of electronic databases identified relevant observational studies, clinical trials, and mechanistic investigations exploring the impact of dairy consumption on headache incidence, frequency, severity, and duration. Methodological considerations, including study design, measurement of exposure and outcome variables, confounding factors, and sources of bias, were critically evaluated to assess the strength of evidence and validity of findings. Despite heterogeneity across studies, emerging evidence suggests a complex and multifaceted relationship between dairy intake and headaches, influenced by individual characteristics, dietary patterns, headache subtype, and study context. While some studies report a positive association between dairy consumption and headaches, others indicate no significant effect or potential therapeutic benefits of dairy restriction. Mechanistic insights suggest plausible biological mechanisms, including neuroinflammatory pathways, neurotransmitter modulation, vascular effects, and gut-brain interactions, which may mediate the observed associations. Future research directions encompass longitudinal studies, mechanistic investigations, stratified analyses, randomized controlled trials, and exploration of the gut microbiota to further elucidate the underlying mechanisms and inform evidence-based dietary recommendations for headache management. This integrative review underscores the importance of interdisciplinary collaboration and personalized approaches to address the complex interplay between diet, headaches, and overall health.

RESUMO

The gradual ageing of the world population has been accompanied by a dramatic increase in the prevalence of obesity and metabolic diseases, especially type 2 diabetes. The adipose tissue dysfunction associated with ageing and obesity shares many common physiological features, including increased oxidative stress and inflammation. Understanding the mechanisms responsible for adipose tissue dysfunction in obesity may help elucidate the processes that contribute to the metabolic disturbances that occur with ageing. This, in turn, may help identify therapeutic targets for the treatment of obesity and age-related metabolic disorders. Because oxidative stress plays a critical role in these pathological processes, antioxidant dietary interventions could be of therapeutic value for the prevention and/or treatment of age-related diseases and obesity and their complications. In this chapter, we review the molecular and cellular mechanisms by which obesity predisposes individuals to accelerated ageing. Additionally, we critically review the potential of antioxidant dietary interventions to counteract obesity and ageing.

RESUMO

BACKGROUND: Telehealth-based dietary interventions were recommended for cardiovascular disease (CVD) management during the COVID-19 pandemic; however, data regarding their effectiveness and feasibility are limited. OBJECTIVE: We aimed to examine (1) the effectiveness of telehealth-based dietary interventions in improving clinical CVD risk factors and (2) the feasibility of these interventions among individuals with CVD. METHODS: To conduct this systematic review and meta-analysis of randomized controlled trials (RCTs), 2 investigators searched PubMed, Cochrane Library, Web of Science, and ClinicalTrials.gov databases based on predetermined search terms and included English-language RCTs published between January 2000 and July 2022. The Cochrane Risk of Bias tool was used to assess RCT quality. To evaluate intervention effectiveness, weight, BMI, systolic and diastolic blood pressure, and levels of total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, triglycerides, or blood glucose were compared postintervention in telehealth and usual care (UC) groups. Feasibility was determined through the number of participants retained in intervention and UC groups. Pooled data for each CVD outcome were analyzed using a random effects model. Mean difference (MD), standardized MD, or risk ratio were calculated using R software. RESULTS: A total of 13 RCTs with 3013 participants were included in the analysis to assess the effectiveness and feasibility of telehealth-based dietary interventions among individuals with CVD. Participants had a mean age of 61.0 (SD 3.7) years, and 18.5% (n=559) were women. Approximately one-third of RCTs were conducted in the United States (n=4, 31%). Included studies used telephone, app, text, audio-visual media, or website-based interventions. Of the 13 included studies, 3 were of high quality, 9 were of moderate quality, and only 1 was of low quality. Pooled estimates showed systolic blood pressure (MD -2.74, 95% CI -4.93 to -0.56) and low-density lipoprotein cholesterol (standardized MD -0.11, 95% CI -0.19 to -0.03) to be significantly improved among individuals with CVD as a result of telehealth-based dietary interventions compared to UC. No significant difference in effectiveness was detected for weight, BMI, and levels of diastolic blood pressure, total cholesterol, high-density lipoprotein, and triglycerides between telehealth-based dietary interventions and UC among those with CVD. There was no significant difference between the feasibility of telehealth-based dietary interventions versus UC. Significant I2 indicated moderate to considerable heterogeneity. CONCLUSIONS: Telehealth-based dietary interventions show promise in addressing CVD risk factors.

RESUMO

Obesity and the associated metabolic syndrome is considered a pandemic whose prevalence is steadily increasing in many countries worldwide. It is a complex, dynamic, and multifactorial disorder that presages the development of several metabolic, cardiovascular, and neurodegenerative diseases, and increases the risk of cancer. In patients with newly diagnosed cancer, obesity worsens prognosis, increasing the risk of recurrence and decreasing survival. The multiple negative effects of obesity on cancer outcomes are substantial, and of great clinical importance. Strategies for weight control have potential utility for both prevention efforts and enhancing cancer outcomes. Presently, time-restricted eating (TRE) is a popular dietary intervention that involves limiting the consumption of calories to a specific window of time without any proscribed caloric restriction or alteration in dietary composition. As such, TRE is a sustainable long-term behavioral modification, when compared to other dietary interventions, and has shown many health benefits in animals and humans. The preliminary data regarding the effects of time-restricted feeding on cancer development and growth in animal models are promising but studies in humans are lacking. Interestingly, several short-term randomized clinical trials of TRE have shown favorable effects to reduce cancer risk factors; however, long-term trials of TRE have yet to investigate reductions in cancer incidence or outcomes in the general population. Few studies have been conducted in cancer populations, but a number are underway to examine the effect of TRE on cancer biology and recurrence. Given the simplicity, feasibility, and favorable metabolic improvements elicited by TRE in obese men and women, TRE may be useful in obese cancer patients and cancer survivors; however, the clinical implementation of TRE in the cancer setting will require greater in-depth investigation.

RESUMO

PURPOSE: Reporting guidelines facilitate quality and completeness in research reporting. The CONsolidated Standards Of Reporting Trials (CONSORT) statement is widely applied to dietary and nutrition trials but has no extension specific to nutrition. Evidence suggests poor reporting in nutrition research. The Federation of European Nutrition Societies led an initiative to make recommendations for a nutrition extension to the CONSORT statement towards a more robust reporting of the evidence base. METHODS: An international working group was formed of nutrition researchers from 14 institutions in 12 different countries and on five continents. Using meetings over a period of one year, we interrogated the CONSORT statement specifically for its application to report nutrition trials. RESULTS: We provide a total of 28 new nutrition-specific recommendations or emphasised recommendations for the reporting of the introduction (three), methods (twelve), results (five) and discussion (eight). We also added two additional recommendations that were not allocated under the standard CONSORT headings. CONCLUSION: We identify a need to provide guidance in addition to CONSORT to improve the quality and consistency of the reporting and propose key considerations for further development of formal guidelines for the reporting of nutrition trials. Readers are encouraged to engage in this process, provide comments and conduct specific studies to inform further work on the development of reporting guidelines for nutrition trials.

RESUMO

OBJECTIVE: Although typically serving higher income and younger demographic groups, meal-kit subscription services have the potential to improve food availability and dietary quality in communities experiencing low food access due to systemic discrimination. This study describes the development and characteristics of a pilot community-led meal-kit service (SouthEats) and evaluates key implementation outcomes of adoption, acceptability, and feasibility among households experiencing less income. DESIGN: We utilised a mixed methods study design, including data from administrative records, customer surveys and worker interviews. Thematic qualitative analyses and descriptive quantitative analyses were conducted to illuminate the characteristics and extent the pilot meal-kit service was adopted, acceptable, and financially feasible among the target populations. SETTING: The study took place in Washington DC, USA. PARTICIPANTS: Study participants included SouthEats consumers (n 35) and workers (n 3). RESULTS: During the pilot period, sixty-seven community members signed up for the meal-kit service, with 52 % making recurring purchases. Our results suggest that the meal-kit service is acceptable among people living in low food access areas. Our feasibility analysis indicates that, although not without challenges, the SouthEats model could be financially feasible. CONCLUSION: These preliminary insights can inform the scalability and potential replication of this service and provide foundational evidence for an approach that may be used to improve food access.

RESUMO

OBJECTIVE: Several studies report weight gain after kidney transplantation, which is commonly related to poor outcomes. However, recommendations for dietary interventions aiming to manage these patients' weight are still scarce in the literature. Thus, this review seeks to describe the state of literature on the effect of dietary interventions on weight after kidney transplantation. DESIGN: Scoping review. METHODS: This review was designed according to the recommendations for scoping reviews elaborated by the Joanna Briggs Institute. Studies assessing the effect of dietary interventions on body weight after kidney transplantations were searched in MEDLINE, EMBASE, and Clinicaltrials.gov databases up to June 28, 2021. Two independent reviewers summarized the data collected. RESULTS: Thirteen (503 patients) of the 4.983 articles identified in the searched databases were included in our study. Most studies were published before 2010 and presented incomplete methodology descriptions. Nutritional counseling and dietary prescriptions according to the Step 1 diet of the American Heart Association (AHA) were the most common interventions. Only 2 studies evaluated changes in body weight as primary outcome. Three studies were randomized clinical trials (RCT), and none of these found the adopted interventions to demonstrate benefits. CONCLUSION: Our scoping review evinced a scarcity of data available in the literature addressing this topic. Most studies were not controlled and presented poor methodological quality. Moreover, these studies included small sample sizes, so that the assessment of dietary interventions in these patients still lacks power for definitive conclusions. Prospective RCT should be conducted to define effective in preventing weight gain or weight loss after kidney transplant.

RESUMO

The salutogenic model of health (SMH) is a health-promoting theory that focuses on resources, strengths, and coping capacities in everyday life as a way to improve health and wellbeing. The SMH was applied to develop a programme for enabling healthy eating practices among people with type 2 diabetes mellitus (T2DM): the SALUD programme. This study aims to gain insight in how participants with T2DM experienced the content and meaning of the SALUD programme. Three focus groups with participants (six to eight participants/group) that finished the SALUD programme were conducted. The focus groups were video-recorded, transcribed ad verbatim and thematically analysed. The SALUD programme was perceived by the participants as a positive, meaningful learning experience. Key factors why the participants described the programme as positive were that they felt a sense of social-belonging and (emotionally) safe (theme 1). The SALUD programme's positive encouraging approach presented by the coach invited participants to join an active learning process (theme 2). Performing trial-and-error experiments and weekly reflecting on goals is what characterized active learning. The meaningfulness of the learning process (theme 3) was derived from (i) positive self-confrontation; (ii) exploring mind-body connections and perceiving improved health and (iii) noticing positive changes in their social environment (theme 3). To conclude, the study uncovered that the SALUD programme incited a positive, meaningful learning process for healthy eating and the contextual factors important in this. Potential leads to further improve the SALUD programme are discussed in order to maximize the chance of inciting an inclusive, active learning process.

RESUMO

Inborn errors of metabolism (IEMs) comprise a diverse group of monogenic disorders caused by enzyme deficiencies that result either in a toxic accumulation of metabolic intermediates or a shortage of essential end-products. Certain IEMs, like phenylketonuria (PKU), necessitate stringent dietary intervention that could lead to microbiome dysbiosis, thereby exacerbating the clinical phenotype. The objective of this systematic review was to examine the impact of PKU therapies on the intestinal microbiota. This research was conducted following the PRISMA Statement, with data from PubMed, Scopus, ScienceDirect, and Web of Science. A total of 18 articles meeting the inclusion criteria were published from 2011 to 2022. Significant reductions in several taxonomic groups in individuals with PKU when compared to the control group were detected in a quantitative analysis conducted across seven studies. The meta-analysis synthesis indicates a contrast in biodiversity between PKU subjects and the control population. Additionally, the meta-regression results, derived from the Bacillota/Bacteroidota ratio data, suggest a potential influence of diet in adult PKU populations (p = 0.004). It is worth noting that the limited number of studies calls for further research and analysis in this area. Our findings indicate the necessity of enhancing understanding of microbiota variability in reaction to treatments among PKU subjects to design tailored therapeutic and nutritional interventions to prevent complications resulting from microbiota disruption.
