Food prices are a daily concern in many households’ decision-making, especially when people want to have healthier diets. Employing Bayesian Mindsponge Framework (BMF) analytics on a dataset of 710 Indonesian citizens, we found that people from wealthier households are less likely to have concerns about food prices. However, the degree of health considerations in food consumption was found to moderate against the above association. In other words, people of higher income-based social classes may worry more about food prices if (...) they care more about the health impacts of their food choices. These findings provide more insights for policymakers on the psychological aspects of promoting the balance between finance and health in food consumption. (shrink)

Dietary changes can alter the human microbiome with potential detrimental consequences for health. Given that environment, health, and evolution are interconnected, we ask: Could diet‐driven microbiome perturbations have consequences that extend beyond their immediate impact on human health? We address this question in the context of the urgent health challenges posed by global climate change. Drawing on recent studies, we propose that not only can diet‐driven microbiome changes lead to dysbiosis, they can also shape (...) life‐history traits and fuel human evolution. We posit that dietary shifts prompt mismatched microbiome‐host genetics configurations that modulate human longevity and reproductive success. These mismatches can also induce a heritable intra‐holobiont stress response, which encourages the holobiont to re‐establish equilibrium within the changed nutritional environment. Thus, while mismatches between climate change‐related genetic and epigenetic configurations within the holobiont increase the risk and severity of diseases, they may also affect life‐history traits and facilitate adaptive responses. These propositions form a framework that can help systematize and address climate‐related dietary challenges for policy and health interventions. (shrink)

Feminist scholars have long demonstrated how women are constrained through dieting discourse. Today’s scholars wrestle with similar themes, but confront a thornier question: how do we make sense of a food discourse that frames food choices through a lens of empowerment and health, rather than vanity and restriction? This article addresses this question, drawing from interviews and focus groups with women (N = 100), as well as health-focused food writing. These data allow us to document a postfeminist food (...) discourse that we term the do-diet. The do-diet reframes dietary restrictions as positive choices, while maintaining an emphasis on body discipline, expert knowledge, and self-control. Our analysis demonstrates how the do-diet remediates a tension at the heart of neoliberal consumer culture: namely, the tension between embodying discipline through dietary control and expressing freedom through consumer choice. With respect to theory, our analysis demonstrates how the embodied dimensions of neoliberalism find gendered expression through postfeminism. We conclude that the do-diet heightens the challenge of developing feminist critiques of gendered body ideals and corporeal surveillance, as it promises a way of eating that is both morally responsible and personally empowering.

The COVID-19 pandemic has brought to light significant failures and fragilities in our food, health, and market systems. Concomitantly, it has emphasized the urgent need for a critical re-evaluation of many of the policies and practices that have created the conditions in which viral pathogens can spread. However, there are many factors that are complicating this process; among others, the uncertain, rapidly evolving, and often poorly reported science surrounding the virus’ origins has contributed to a politically charged and often (...) rancorous public debate, which is concerning insofar as the proliferation of divisive discourse may hinder efforts to address complex and collective concerns in a mutually cooperative manner. In developing ethical and effective responses to the disproportionate risks associated with certain food production and consumption practices, we argue that the focus should be on mitigating such risks wherever they arise, instead of seeking to ascribe blame to specific countries or cultures. To this end, this article is an effort to inject some nuance into contemporary conversations about COVID-19 and its broader implications, particularly when it comes to trade in wildlife, public health, and food systems reform. If COVID-19 is to represent a turning point towards building a more equitable, sustainable, and resilient world for both humans and nonhuman animals alike, the kind of fractioning that is currently being exacerbated by the use of loaded terms such as “wet market” must be eschewed in favour of a greater recognition of our fundamental interconnectedness.

BackgroundSleep, physical activity, and diet have been associated with mental health and well-being individually in young adults. However, which of these “big three” health behaviors most strongly predicts mental health and well-being, and their higher-order relationships in predictive models, is less known. This study investigated the differential and higher-order associations between sleep, physical activity, and dietary factors as predictors of mental health and well-being in young adults.MethodIn a cross-sectional survey design, 1,111 young adults ages 18–25 (...) from New Zealand and the United States answered an online survey measuring typical sleep quantity and quality; physical activity; and consumption of raw and processed fruit and vegetables, fast food, sweets, and soda, along with extensive covariates and the outcome measures of depressive symptoms [measured by the Center for Epidemiological Depression Scale ] and well-being.ResultsControlling for covariates, sleep quality was the strongest predictor of depressive symptoms and well-being, followed by sleep quantity and physical activity. Only one dietary factor—raw fruit and vegetable consumption—predicted greater well-being but not depressive symptoms when controlling for covariates. There were some higher-order interactions among health behaviors in predicting the outcomes, but these did not survive cross-validation.ConclusionSleep quality is an important predictor of mental health and well-being in young adults, whereas physical activity and diet are secondary but still significant factors. Although strictly correlational, these patterns suggest that future interventions could prioritize sleep quality to maximize mental health and well-being in young adults. (shrink)

This edited volume explores the intersection of medicine and philosophy throughout history, calling attention to the role of quantification in understanding the medical body. Retracing current trends and debates to examine the quantification of the body throughout the early modern, modern and early contemporary age, the authors contextualise important issues of both medical and philosophical significance, with chapters focusing on the quantification of temperaments and fluids, complexions, functions of the living body, embryology, and the impact of quantified reasoning on the (...) concepts of health and illness. With insights spanning from the sixteenth century to the nineteenth century, this book provides a wide-ranging overview of attempts to ‘quantify’ the human body at various points. Arguing that medicine and philosophy have been constantly in dialogue with each other, the authors discuss how this provided a strategic opportunity both for medical thought and philosophy to refine and further develop. Given today’s fascination with the quantification of the body, represented by the growing profusion of self-tracking devices logging one’s sleep, diet or mood, this collection offers an important and timely contribution to an emerging and interdisciplinary field of study. -/- .

Integrated developmental and elemental information in teeth provide a unique framework for documenting breastfeeding histories, physiological disruptions, and neurotoxicant exposure in humans and our primate relatives, including ancient hominins. Here we detail our method for detecting the consumption of mothers’ milk and exploring health history through the use of laser ablation‐inductively coupled plasma‐mass spectrometry (LA‐ICP‐MS) mapping of sectioned nonhuman primate teeth. Calcium‐normalized barium and lead concentrations in tooth enamel and dentine may reflect milk and formula consumption with minimal modification (...) during subsequent tooth mineralization, particularly in dentine. However, skeletal resorption during severe illness, and bioavailable metals in nonmilk foods, can complicate interpretations of nursing behavior. We show that explorations of the patterning of multiple elements may aid in the distinction of these important etiologies. Targeted studies of skeletal chemistry, gastrointestinal maturation, and the dietary bioavailability of metals are needed to optimize these unique records of human health and behavior. (shrink)

Secondary lymphoid organs form in utero through an inherited and well‐established developmental program. However, maternal non‐heritable features can have a major impact on the gene expression of the embryo, hence influencing the future health of the offspring. Recently, maternal retinoids were shown to regulate the formation of immune structures, shedding light on the role of maternal nutrition in the genetic signature of emergent immune cells. Here we highlight evidence showing how the maternal diet influences the establishment of the (...) immune system, and we also discuss how unbalanced maternal diets may set the response to infection and vaccination in the progeny.

Infants, children, adolescents, and pregnant and lactating women have been described as groups with special needs. Regardless of diet chosen, these groups are at higher risk for nutritional deficiencies than adult males. Vegan diets can be safely used by these groups if foods, and in some instances supplements, are selected which provide a healthful and nutritionally adequate diet. Guidelines have been developed for those choosing to follow vegan diets. In many instances vegan diets offer health benefits. Studies (...) of vegans are limited by factors such as heterogeneity of diets, the size and extent of this type of study, and difficulty in subject identification. There is a scarcity of studies of newer vegetarians who are often more mainstream than the vegetarians of the 1960s and 1970s. In some instances this has led to assumptions about today's vegans which are based on out-dated information. Thorough scientific studies of today's vegetarians, especially of those in groups with special needs, are needed. (shrink)

Epidemiological evidence supports a health‐promoting effect of the Mediterranean Diet (MedDiet), especially in the prevention of cardiovascular diseases. These cardiovascular benefits have been attributed to a number of components of the MedDiet such as monounsaturated fatty acids, antioxidant vitamins and phytochemicals. However, the underlying mechanisms remain unknown. Likewise, little is known about the genes that define inter‐individual variation in response to the MedDiet, although the TCF7L2 gene is emerging as an illustrative candidate for determining relative risk of cardiovascular (...) events in response to the MedDiet. Moreover, omics technologies are providing evidence supporting potential mechanisms, some of them implicating epigenetics (i.e. microRNAs, methylation), and certain data suggest that some traditional foods could contribute via microRNAs possibly acting as exogenous regulators of gene expression. Future research should aim at increasing and consolidating the nutrigenetic and nutrigenomic knowledge of the MedDiet in order to provide sound, personalized and optimized nutritional recommendations.

Mediating role of coping styles in the relationship between anxiety and health behaviors of obese adolescents Obesity is one of the major health problems in adolescents. Health-detrimental lifestyle as well as maladaptive styles of coping with stress are regarded as belonging among determinants of obesity. The aim of the study was to establish factors mediating between anxiety and diet-related health behaviors. Participants in the study were 113 adolescents with obesity whose body weight was over 97th (...) centile. They were examined using a set of self-report questionnaires to measure anxiety, coping styles and health behaviors. Emotion-focused coping and seeking social contacts were found to act as mediators between adolescents' trait anxiety and their health behaviors. The findings suggest that to enhance obese adolescents' health-promoting behaviors appropriate conditions should be ensured that would not only enable them to express their emotions, but also promote their socializing with peers.

In this paper, I intend to analyze Baumgarten’s position about the dietetic care of the body in its relation to nascent aesthetics, with special regard to the problem of physical exercise. On the one hand, I will show that physical exercise can acquire aesthetic value with the example of the somatic fine arts. On the other hand, I will demonstrate that dietetics is also seminal for the emergence of every act of beautiful thinking. Eventually, I will bring to the fore (...) the dietetic potential of beauty itself. In this way, it will be possible to better appraise the constitutive link between health and beauty in the founding of aesthetics as an independent branch of philosophy. (shrink)

There has been an increase in research that focuses on female adolescents and adult women concerns relating to body image and dieting concerns. However, research on body and dieting concerns of specifically pre-adolescents is still a neglected area of research in comparison with female adolescents and adult women. Pre-adolescents are either research participants as part of a group, which includes younger children, or part of a group of adolescents. This article addresses the body and dieting concerns of pre-adolescent females as (...) a group on their own. A qualitative study was conducted, and data were collected by using a vignette with semi-structured questions. The data were analysed by using a thematic analysis. The results indicated that although the girls presented a ‘polite’ discourse that all girls should be accepted irrespective of weight, when they were futher engaged with during the interviews this was not reflective of their world view. Negative attributes were projected onto the heavier girl in the vignette, and the discourse of acceptance was linked to feelings of pity and sympathy as fat girls were ‘handicapped’ albeit not because of their own doing. Thin girls were linked to positive traits, such as kind, happy and with leadership potential. The pre-teens in the sample were all very familiar with terms related to food restrictions (dieting), and a number of them had indulged in dieting behaviour to lose weight. The research was conducted in one province in South Africa and provides baseline data for a bigger study, which includes other provinces, as well as girls from rural areas and girls from schools in poorer urban areas. The results indicated that the pre-teen girls have internalised gendered notions of what it means to be female and being thin is integrally linked to what patriarchy has constructed as the ideal female body. Contribution: This article is grounded within the discipline of Psychology. However, the scholarly contribution it intersects with include the disciplines of Public Health, Education and Gender Studies. It provides and engages a discourse at the intersections of the Social Sciences and Humanities disciplines, contributing to knowledge which is interdisciplinary and multidisciplinary. (shrink)

This article aims to conduct a conceptual and diachronic review on the construction of the Mediterranean diet as a subject of analysis from a social point of view, connecting nutrition with the most actual social and political challenges and preoccupations. The concept of the Mediterranean diet came into being shortly after the mid-twentieth century as a recommended and healthy diet, mainly aimed at North American society. Since then, it has undergone various modifications that have led it from (...) being a concept linked solely to health, to an element of culture, and a lifestyle, as a result of its declaration as intangible cultural heritage by UNESCO in 2010 (and its extension to other three additional countries in 2013). Since that point, the Mediterranean diet has adopted a new path, guided by the FAO, as a sustainable diet, focusing on sustainability and locality as the cornerstones of its new identity. A historic transformation of the concept of the Mediterranean Diet is therefore apparent, which has taken it from health to sustainability, through culture. However, it is also evident that the focus on health has never really declined in its importance, but has instead adapted to the times, and been modified to suit new food trends. (shrink)

Genetics offers real opportunities for public health actors. Increased understanding of genetics will illuminate some of the factors that affect disease and, in many cases, will lead to more effective treatments. The recognition that phenylketonuria was caused by a metabolic defect that led to the accumulation of toxic levels of phenylalanine, an elevation that could largely be averted by adopting a low-phenylalanine diet, is an early example. Some cases of what was thought to be Sudden Infant Death Syndrome, (...) a diagnosis used when no etiology is known, now appear to have been caused by metabolic defects in fatty acid oxidation and sodium channel defects. One of the tasks that has already been undertaken by the public health sector is to ensure that genomic information is incorporated into clinical care when the robusmess of findings and their clinical utility have been well defined.

From 1900 onwards, scientists and novelists have explored the contours of a future society based on the use of “anthropotechnologies” (techniques applicable to human beings for the purpose of performance enhancement ranging from training and education to genome-based biotechnologies). Gradually but steadily, the technologies involved migrated from (science) fiction into scholarly publications, and from “utopia” (or “dystopia”) into science. Building on seminal ideas borrowed from Nietzsche, Peter Sloterdijk has outlined the challenges inherent in this development. Since time immemorial, and at (...) least since the days of Plato’s Academy, human beings have been interested in possibilities for (physical or mental) performance enhancement. We are constantly trying to improve ourselves, both collectively and individually, for better or for worse. At present, however, new genomics-based technologies are opening up new avenues for self-amelioration. Developments in research facilities using animal models may to a certain extent be seen as expeditions into our own future. Are we able to address the bioethical and biopolitical issues awaiting us? After analyzing and assessing Sloterdijk’s views, attention will shift to a concrete domain of application, namely sport genomics. For various reasons, top athletes are likely to play the role of genomics pioneers by using personalized genomics information to adjust diet, life-style, training schedules and doping intake to the strengths and weaknesses of their personalized genome information. Thus, sport genomics may be regarded as a test bed where the contours of genomics-based self-management are tried out. (shrink)

Relationships, jobs, and health behaviors-these are what New Year's resolutions are made of. Every year millions resolve to adopt a better diet, exercise more, become fit, or lose weight but few put into practice the health behaviors they aspire to. For those who successfully begin, the likelihood that they will maintain these habits is low. Healthcare professionals recognize the importance of these, and other, health behaviors but struggle to provide their patients with the tools necessary for (...) successful maintenance of their medical regimens. The thousands of research papers that exist on patient adherence and health behavior change can leave professionals overwhelmed. This book synthesizes the results from more than 50 years of empirical research, resulting in simple, powerful, and practical guidance for health professionals who want to know the most effective strategies for helping their clients to put long-term health-relevant behavior changes into practice. It advocates a straightforward 3-ingredient model: Before a person can change, they must know what change is necessary ; desire the change ; and then have the tools to achieve and maintain the change. This book is designed to be informative and compelling, but its numerous anecdotes and examples render it engaging and entertaining, as well. Written for a practitioners and students of medicine, chiropractic, osteopathy, nursing, health education, physician assistant programs, dentistry, clinical and health psychology, marriage and family counseling, social work, school psychology, and care administrators -- and for lay persons who wish to take an active role in their health, this book brings together major empirically-based findings within the field and provides succinct, evidence-based recommendations and strategies for using these findings to make real changes.

This work brings together Philip van der Eijk's previously published essays on the close connections that existed between medicine and philosophy throughout antiquity. Medical authors such as the Hippocratic writers, Diocles, Galen, Soranus and Caelius Aurelianus elaborated on philosophical methods such as causal explanation, definition and division and applied key concepts such as the notion of nature to their understanding of the human body. Similarly, philosophers such as Plato and Aristotle were highly valued for their contributions to medicine. This interaction (...) was particularly striking in the study of the human soul in its relation to the body, as illustrated by approaches to specific topics such as intellect, sleep and dreams, and diet and drugs. With a detailed introduction surveying the subject as a whole and an essay on Aristotle's treatment of sleep, this wide-ranging and accessible collection is essential reading for the student of ancient philosophy and science.

Biology incorporated into other disciplines is often distorted, alarmingly so in some areas of medicine. Together with other forms of bias, this may have detrimental effects for patients depending on medical research for their health. A case study concerning omeprazole (Losec), one of the acid-suppressive drugs against gastric ulcers, and NSAIDs, non-steroid anti-inflammatory drugs, confirms that distorted biology together with biased health care policies foster disasters in current biomedicine and medical practice. In our country, The Netherlands, omeprazole is (...) presumably the most commonly used medication. NSAIDs are also used in large quantities, increasingly since they have become available as analgesic over-the-counter drugs. Unofficial and official sources tend to inform the general public that the drugs promote human health. We argue that their being used on a massive scale is actually a medical disaster. The health of many patients would be served better if the drugs they take were replaced by proper forms of diet, but the pharmaceutical industry, the most potent force affecting medication policies, appears to prevent a shift in the balance from over-medicalization towards healthy life styles. The shift should come from government agencies responsible for regulation in the medication market. Policies of these agencies are now a dismal failure. (shrink)

Critics of mass culture often identify 1950s-style status competition as one of the central forces driving consumerism.

This paper provides a rearticulation and defense of Frank's thesis, first identifying consumerism as a type of collective action problem, then showing how the ‘hip consumer’ is one who adopts a free-rider strategy in this (...) context.

In this chapter, I consider how an analysis of responsibility for habitual behaviour can help us to make judgements about people’s responsibility for their health. Much of our behaviour is habitual, featuring high levels of automaticity and low levels of reflection. Further, habitual behaviour is particularly commonplace in many “everyday” health-affecting actions like diet and physical activity. It is unclear what role conscious awareness plays in habitual behaviour, but it is generally assumed that conscious control over habitual (...) behaviour is limited, if not completely lacking, at least at the time that behaviour is performed. There has been relatively little written about responsibility for habitual behaviour. At least, few philosophical accounts of responsibility have explicitly discussed habitual behaviour or habits. A notable exception is Fischer and Ravizza’s influential Responsibility and Control, which makes reference to behaviour that is performed “instinctively” or out of “unreflective habit”. There is also a significant literature on responsibility for character, which could be considered of direct relevance to attempts to illuminate responsibility for habitual behaviour. This chapter will outline what work remains to be done in order to properly align discussions of responsibility with a psychologically informed analysis of habitual behaviour, and will indicate how this could support discussions of people’s responsibility for their health.

The potential health risks of vegan diets specifically for women and children are discussed. Women and children are at higher risk of malnutrition from consumption of unsupplemented vegan diets than are adult males.

The size of these risks is difficult to quantify from existing studies. Fortunately the risk of dietary deficiency disease can be avoided and the (...) potential health benefits of vegan diets can be realized when diets for these groups are planned in line with theRecommended Dietary Allowances so that nutrient intakes reach or exceed recommended levels, and access to preventive and curative health services is assured.

Paul B. Thompson’s From the Field to Fork: Food Ethics for Everyone explains the growing number of ways that food connects to ethical questions concerning our consumption, production, storage, and distribution of food.

In my comments, I will first briefly provide an overview of Thompson’s thoughtful book. I will explain the methodology employed in this book and how his methodology applies to specific philosophical questions within food ethics.

The ageing population and new technology are both increasing the cost of our free health service, and there are sound economic reasons for extending measures which reduce the diseases common to our society.

Functional foods aim to provide a positive impact on health and well-being beyond their nutritive content. As such, they are likely candidates to enhance the public health official’s tool kit. Or are they? Although a very small number of functional foods (e.g., phytosterol-enriched margarine) show such promise in improving individual health that Dutch health insurance companies reimburse their costs to consumers, one must not draw premature conclusions about functional foods as a group. A large number of (...) questions about individual products’ safety, efficacy, and affordability need to be answered before they might become an important part of the public health agenda. More importantly, though, the costs and benefits of functional foods relative to alternative mechanisms of public health improvement need to be ascertained. Alternative scenarios that warrant investigation are mainly the supply of nutraceutical ingredients in pill form targeting “at risk” groups and consumer education on diet and lifestyle. (shrink)

I argue that, contrary to what Tom Regan suggests, his rights view implies that subsistence hunting is wrong, that is, killing animals for food is wrong even when they are the only available food source, since doing so violates animal rights. We can see that subsistence hunting is wrong on the rights view by seeing why animal experimentation, specifically xenotransplanation, is wrong on the rights view: if it’s wrong to kill an animal to take organs to save a human life, (...) it’s wrong to kill an animal to eat that animal to save a human life or improve human health. I discuss these arguments’ implications for animal rights-based vegan advocacy, insofar as some people claim that they don’t feel their best on vegan diets and so their eating meat is morally justified. I argue that such an attempt to justify consuming animal products fails on Regan’s rights view, but discuss some attempts to morally excuse such violations of animals’ rights. These attempts are inspired by Regan’s attempts at potentially excusing animal rights advocates’ using medications developed using animals. (shrink)

Attention has become increasingly focused in recent years on the role agri-food system transformations have played in driving the global diet-related chronic disease burden. Identifying the role played by the food-consuming industries (predominantly large manufacturers, processors, distributors, and retailers) in particular, and identifying possibilities to facilitate healthier diets through intervening in these industries, have been identified as a research priority. This paper explores the potential for one promising analytic framework—the nutrition-oriented value chain approach—to contribute to this area, drawing on (...) recent insights from the global value chain (GVC) literature to develop an institutionally-enriched approach. The research focused on a canned deciduous fruit value chain linking growers, processors, and retailers in South Africa and Australia. Findings reveal the multiple drivers which have converged to shape this value chain over time, and the key actors which are influencing product availability, composition, price, and promotion within this sector. With its emphasis on identifying implications for end-consumption, rather than economic outcomes within the chain, nutrition-oriented value chain research represents a significant shift in focus for the GVC framework. Therefore, an immediate opportunity for further research is to extend the analytic framework to primary research on end-consumption behaviours. (shrink)

Issues arising in connection with genes and nutrition policy include both nutrigenomics and nutrigenetics. Nutrigenomics considers the relationship between specifc nutrients or diet and gene expression and, it is envisaged, will facilitate prevention of diet-related common diseases. Nutrigenetics is concerned with the effects of individual genetic variation on response to diet, and in the longer term may lead to personalised dietary recommendations. It is important also to consider the surrounding context of other issues such as novel and (...) functional foods in so far as they are related to genetic modification. Ethical issues fall into a number of categories: why nutrigenomics? Will it have important public health benefits? questions about research, e.g. concerning the acquisition of information about individual genetic variation; questions about who has access to this information, and its possible misuse; the applications of this information in terms of public health policy, and the negotiation of the potential tension between the interests of the individual in relation to, for example, prevention of conditions such as obesity and allergy; the appropriate ethical approach to the issues, e.g. the moral difference, if any, between therapy and enhancement in relation to individualised diets; whether the 'technological fix' is always appropriate, especially in the wider context of the purported lack of public confidence in science, which has special resonance in the sphere of nutrition.

With the proviso that Spinoza's concerns were philosophical, not medical, we examine the Ethics with a view to bringing out those aspects of it which are of import for mental health. We find that the Ethics surrounds the idea that man can be egoless in the Buddhist sense of that term. This concept provides a criterion of mental health. Further, according to Spinoza's theory of the Affections, those which are passive include some which are based on pain. These (...) he 'enumerates among the diseases'. And for them he provides, in Part V, specific 'remedies'. This in turn leads him to equate 'Mental Freedom or beatitude' with a 'healthy Mind'. We thus have in Part V additional possible criteria of mental health. Finally, there is the suggestion that philosophy for Spinoza was a kind of therapy.'

BROOKS J and RAFFERTY AM. Nursing Inquiry 2010; 17: 142–150Education and role conflict in the health visitor profession, 1918–39Health visiting was the public health profession in the UK, which arose during the Victorian period to support and supervise the mothers of the nation. The health visitor was expected to teach the new mothers hygiene, infant feeding and diet, help them in the home when necessary and then report back to the Medical Officer for Health. Her (...) role therefore was multifaceted and required education and training from a number of differing bodies. She needed nursing skills to help with the practicalities of observation and home care, sanitary knowledge to ensure that the buildings were safe and training in law and epidemiology. In order to fulfil these professional requirements, by the middle of the twentieth century the health visitor was expected to be a nurse by background, be educated for health visiting in a university and understand community medicine. These differing and sometimes opposing requirements meant that the health visitor was often caught in-between conflicting ideologies. It is this idea of ‘in-betweenness’ from the work of the anthropologist Marilyn Strathern and its relation to the work and education of the health visitor that this article will focus. (shrink)

Background: Meditation is gaining recognition as a tool to impact health and well-being. Samyama is an 8-day intensive residential meditation experience conducted by Isha Foundation requiring several months of extensive preparation and vegan diet. The health effects of Samyama have not been previously studied. The objective was to assess physical and emotional well-being before and after Samyama participation by evaluating psychological surveys and objective health biomarkers.Methods: This was an observational study of 632 adults before and after (...) the Isha Samyama retreat. All participants were invited to complete surveys. Controls included household significant others. Surveys were completed at baseline, just before Samyama, immediately after Samyama, and 3 months later to assess anxiety, depression, mindfulness, joy, vitality, and resilience through validated psychometric scales. Voluntary blood sampling for biomarker analysis was done to assess hemoglobin, HbA1c, lipid profile, and C-reactive protein. Primary outcomes were changes in psychometric scores, body weight, and blood biomarkers.Results: Depression and anxiety scores decreased from T1 to T3, with the effect most pronounced in participants with baseline depression or anxiety. Scores at T4 remained below baseline for those with pre-existing depression or anxiety. Vitality, resilience, joy, and mindfulness increased from T1 to T3. Body weight decreased by 3% from T1 to T3. Triglycerides were lower from T2 to T3. Participants had lower HbA1c and HDL at T2, and lower CRP at all timepoints compared with controls.Conclusions: Participation in the Isha Samyama program led to multiple benefits. The 2-month preparation reduced anxiety, and participants maintained lower anxiety levels at 3 months post-retreat. Physical health improved over the course of the program as evidenced by weight loss and improved HbA1C and lipid profile. Practices associated with the Samyama preparation phase and the retreat may serve as an effective way to improve physical and mental health. Future studies may examine their use as an alternative therapy in patients with depression and/or anxiety.Clinical Trial Registration:www.ClinicalTrials.gov, Identifier: 1801728792.
