Introduction: Christian Orthodox fasting is a pattern high in complex carbohydrates and low in refined carbohydrates. It has been explored in association with its potential health benefits. The present review aims to comprehensively explore the existing available clinical data concerning the potential favorable impact of the dietary pattern of Christian Orthodox fasting on human health. Methods: PubMed database, Web of Science and Google Scholar were extensively searched in order to identify the more appropriate clinical studies that explore the effect of Christian Orthodox fasting on health-related outcomes in humans utilizing relative keywords. We initially retrieved 121 records through database searching. After applying several exclusion criteria, 17 clinical studies were finally included in this review study. Discussion: Christian Orthodox fasting showed beneficial effects concerning glucose and lipid control, whereas the data for blood pressure remain inconclusive. Concerning weight control, fasters were characterized by lower body mass and lower caloric intake in the course of the fasting periods. During fasting, this pattern is higher in fruits and vegetables, showing the absence of dietary deficiencies for iron and folate. Nevertheless, dietary deficiencies were recorded for calcium and vitamin B2, and also hypovitaminosis D has been noticed in monks. Interestingly, the vast majority of monks do present with both good quality of life and mental health. Conclusions: Overall, Christian Orthodox fasting is a dietary pattern low in refined carbohydrates and high in complex carbohydrates and fiber that may be beneficial for human health promotion and chronic disease prevention. However, further studies are strongly recommended on the impact of long-term religious fasting on HDL cholesterol levels and blood pressure.
Background: The ketogenic diet (KD) has become widespread for the therapy of epileptic pathology in childhood and adulthood. In the last few decades, the current re-emergence of its popularity has focused on the treatment of obesity and diabetes mellitus. KD also exerts anti-inflammatory and neuroprotective properties, which could be utilized for the therapy of neurodegenerative and psychiatric disorders. Purpose: This is a thorough, scoping review that aims to summarize and scrutinize the currently available basic research performed in in vitro and in vivo settings, as well as the clinical evidence of the potential beneficial effects of KD against neurodegenerative and psychiatric diseases. This review was conducted to systematically map the research performed in this area as well as identify gaps in knowledge. Methods: We thoroughly explored the most accurate scientific web databases, e.g., PubMed, Scopus, Web of Science, and Google Scholar, to obtain the most recent in vitro and in vivo data from animal studies as well as clinical human surveys from the last twenty years, applying effective and characteristic keywords. Results: Basic research has revealed multiple molecular mechanisms through which KD can exert neuroprotective effects, such as neuroinflammation inhibition, decreased reactive oxygen species (ROS) production, decreased amyloid plaque deposition and microglial activation, protection in dopaminergic neurons, tau hyper-phosphorylation suppression, stimulating mitochondrial biogenesis, enhancing gut microbial diversity, restoration of histone acetylation, and neuron repair promotion. On the other hand, clinical evidence remains scarce. Most existing clinical studies are modest, frequently uncontrolled, and merely assess the short-term impacts of KD. Moreover, several clinical studies had large dropout rates and a considerable lack of compliance assessment, as well as an increased level of heterogeneity in the study design and methodology. Conclusions: KD can exert substantial neuroprotective effects via multiple molecular mechanisms in various neurodegenerative and psychiatric pathological states. Large, long-term, randomized, double-blind, controlled clinical trials with a prospective design are strongly recommended to delineate whether KD may attenuate or even treat neurodegenerative and psychiatric disease development, progression, and symptomatology.
Summary The analysis of conservation narratives primarily resides in the methods and techniques of social sciences, focusing mainly on uncovering advocacy versus critical lines of thought in the complex mosaic of arguments around institutional actors and the public. Researchers have previously proposed an archetypal scheme in which the core conservation narratives and their conceptual interrelations are classified. This report explores the feasibility of coupling such a traditional method with techniques emanating from quantitative linguistics, network analysis and bibliometry. The neologic metaphor of the Anthropause is purposely added to long-established narratives to examine its potential effects on the conservation narratives landscape. The results show that this metaphor reorganizes the mentally constructed connections between flag narratives and symbolic lexical units.
The term ‘sustainable diets’ (SDs) was first introduced in the scientific literature in 1986 and later defined in detail by the Food and Agriculture Organization (FAO) as pertaining to those diets that can promote environmental health ad effectively ensure food and nutrition security as well as a healthy lifestyle in humans, combining the notion of sustainability with dietary patterns and their beneficial impacts. Since then, various international events have been held promoting sustainability as a significant component of food production, nutrition, and human health. These events have enhanced the knowledge transition and awareness between the scientific community and policymakers concerning the importance of SDs. In this aspect, this is the first study that aims to identify trends and turning points over time concerning the research on SDs. We performed a comprehensive bibliometric analysis of 1407 scientific documents published in Scopus during the period 1986–2022. The documents were screened following the PRISMA guidelines, and bibliometric analysis was conducted using the Bibliometrix R-package and VOSviewer and the detection of Sustainable Development Goals with the text2sdg R-package. Overall, there was an exponential growth in the literature on SDs that followed international events from 2009 onward. Among the most impactful journals were Sustainability, Nutrients, and Frontiers in Nutrition. The leading countries in research were pointed out, as well as the high rate of collaborations and partnerships between them. The research interest was mainly focused on (a) climate change, greenhouse gas emissions, and environmental impact; (b) food systems, security, and consumption; and (c) health, Mediterranean Diet (MD), and dietary guidelines. The significance of these keywords changed over time, following the evolution of SDs concepts from the planetary environmental impact of food production to the healthier dietary habits of individuals. Among several dietary patterns, MD was identified as the most popular among the local SDs, with synergies among scientists in the Mediterranean region. Overall, the novelty of this study is the mapping of the expansion of knowledge over the last 36 years regarding the term SDs while taking into consideration international events and their impact on scientific research.
present different methodological approaches that can be used to investigate problems in a relevant scientific field and to encourage innovation.• Letters to the Editor -a response to authors of an original publication, or a very small article that may be relevant to readers. • Editorials -articles written by members of the Editorial Board. Research PapersArticles reporting research may be full length or brief reports. These should report original research findings within the journal's scope. Papers should generally be a maximum of 4000 words in length, excluding a maximum of 5 tables, references, and abstract of the article, whilst it is recommended that the number of references should not exceed 36. Review PapersComprehensive, authoritative, reviews within the journal's scope. There are two types of review papers:• systematic review papers: respond to a specific research question, accrue from criterion-based selection of sources, include a quantitative synthesis and a statistical method (meta-analysis), and should adhere to PRISMA guidelines. Guidelines used for abstracting data and assessing data quality and validity should be noted in methods section. • narrative review papers: the research question may be broad, and the scope of this review is to discuss a specific topic and keep the readers up-to-date about it. This type of review does not necessarily include a methodological approach and its synthesis is usually qualitative. Narrative reviews should include in a developments section, with details regarding data sources used, keywords applied, time restrictions and study types selected. Developments should be based on actual review articles. All review papers should be generally less than 6000 words, excluding abstract, tables, figures and references. References should not exceed 50. Conclusion of the reviews should be specific and stem from the findings. Short ReportsBrief reports of data from original research. Short reports are shorter versions of original articles, may include one table or figure, should not exceed 1500 words, and it is recommended that the number of references should not exceed 15. Short reports are suitable for the presentation of research that extends previously published research, including the reporting of additional controls and confirmatory results in other settings, as well as negative results. Authors must clearly acknowledge any work upon which they are building, both published and unpublished. Methodology PapersMethodology papers will present different methodological approaches that can be used to investigate problems in a relevant scientific field and to encourage innovation. It is suggested that case studies or practical examples, which can be existing ones, are included to demonstrate the consistency and applicability of the methodology. Methodology papers should be generally less than 6000 words, excluding abstract, tables, figures and references. References should not exceed 50.
