Vegetarismus. Mehr als ein Ernährungsstil

Vegetarianism During recent decades the social standing of vegetarians has improved considerably. Scientific studies show convincingly that a well balanced lacto‐ovo‐vegetarian diet can provide an optimal supply of all nutrients for everybody. Vegetarians practice their nutrition predominantly for ethical reasons, health concerns and ecological considerations. Vegetarianism contributes to global nutrition security and to a sustainable management of natural resources. The switch to a vegetarian diet requires conviction and knowledge about the proper selection and preparation of the diet. Vegetarians report about their high quality of life – not only because they live longer.     

Insekten als Nahrungsmittel der Zukunft

Insects as a sustainable food of the future In Germany insects are still relatively unknown as foodstuff. However, in many countries of the world insects have been valued as foodstuff for a long time. This article examines the sustainability potential of entomophagy. Based on legal and psychological barriers it tries to explain why insects are not on the menu in Germany. Research in the fields of nutritional psychology and biodidactics is essential for the successful introduction of insects as foodstuff in Germany.     

Vielfältiges Leben in Sand und Heide

Excursion in Brandenburg: Species richness in sand heathlands After many decades of an intensive military use, the former military training areas of Eastern Germany play a major role as huge, unfragmented biodiversity hotspots. While intensive agriculture causes a serious threat to many species in our cultural landscape, heathlands and dry grasslands are unique habitats on the nutrient‐poor soils in the “box of sand” of the Mark Brandenburg. But these habitats need a strong conservation management with targeted nursing measures such as removal of shrubs, grazing, soil wounding and controlled burning. However, some forest sites of the military training areas are often suitable for a wilderness development. The Heinz Sielmann Foundation pursues these nature conservation objectives and makes great nature experiences possible in the conservation areas.     

Die Eh da‐Initiative

The “Eh da”‐Initiative: more space for Biological Diversity in Cultural Landscapes The “Eh da”‐initiative is based on the principle that definite land in cultural landscapes is “available anyway” (what ?eh da“ means in German) and has the potential for ecological upgrading without relevant limitations of land use. “Eh da” could be the acronym “Ecological habitat development areas.” This land is located in open landscapes: along waysides, on uncropped plots in farmland, it could be communal lawn and other land categories. The initiative uses geodata in order to detect and quantify “Eh da”‐sites. According to an analysis based on geodata in selected landscapes “Eh da”‐land constitutes 2–6 per cent of the total area of Germany. “Eh da“‐sites are mostly narrow, longitudinal and spread like a net all over the landscape. Mainly insects and other invertebrate animals can be supported by upgrading of “Eh da”‐land. Since these sites often form corridors, they may be part of communal biodiversity protection initiatives under the perspective of ecological networks, or they may be used for distinct projects. Communication is a key element of any local initiative in which not only the ecological upgrading options, but also potential trade‐offs (like increase of agricultural pests and weeds, neophyta and pyrrolizidine containing or allergenic plants) should be discussed.     

Information is not knowledge: Cooking and eating as skilled practice in Australian obesity education

This paper examines the relationship between obesity, knowledge and education in a South Australian community setting. In public health circles and public understandings it is commonly assumed that obesity is the result of lack of knowledge about the right things to eat or how to take care of oneself. It is thought that education will fill this knowledge lacunae and most public health campaigns have education as the main platform of information dissemination to enact behavioural change. Based on long‐standing ethnographic work in a community targeted as obesogenic, I explore the limits of mainstream nutrition education, and how constructing people as having deficit knowledge has the unwarranted effect of implying ignorance. Key to the analysis is Ingold's articulation of different modalities of education, one dominant mode which inducts people into rules and regulations of already pre‐formed knowledge, and another which sees education as learning that goes on in the doing of everyday environments.     

Globalization and loss of plant knowledge: challenging the paradigm

The erosion of cultural knowledge and traditions as a result of globalization and migration is a commonly reported phenomenon. We compared one type of cultural knowledge about medicinal plants (number of plants reported to treat thirty common health conditions) among Dominican laypersons who self-medicate with plants and live in rural or urban areas of the Dominican Republic (DR), and those who have moved to New York City (NYC). Many plants used as medicines were popular Dominican food plants. These plants were reported significantly more often by Dominicans living in NYC as compared to the DR, and this knowledge was not age-dependent. These results contradict the popular paradigm about loss of cultural plant knowledge and is the first study to report a statistically measurable increase in this type of knowledge associated with migration.     

More fishers and fewer martens due to cumulative effects of forest management and climate change as evidenced from local knowledge

Diet and nutrition-related behaviours are embedded in cultural and environmental contexts: adoption of new knowledge depends on how easily it can be integrated into existing knowledge systems. As dietary diversity promotion becomes an increasingly common component of nutrition education, understanding local nutrition knowledge systems and local concepts about dietary diversity is essential to formulate efficient messages. This paper draws on in-depth qualitative ethnographic research conducted in small-scale agricultural communities in Tanzania. Data were collected using interviews, focus group discussions and participant observation in the East Usambara Mountains, an area that is home primarily to the Shambaa and Bondei ethnic groups, but has a long history of ethnic diversity and ethnic intermixing. The data showed a high degree of consensus among participants who reported that dietary diversity is important because it maintains and enhances appetite across days, months and seasons. Local people reported that sufficient cash resources, agrobiodiversity, heterogeneity within the landscape, and livelihood diversity all supported their ability to consume a varied diet and achieve good nutritional status. Other variables affecting diet and dietary diversity included seasonality, household size, and gender. The results suggest that dietary diversity was perceived as something all people, both rich and poor, could achieve. There was significant overlap between local and scientific understandings of dietary diversity, suggesting that novel information on the importance of dietary diversity promoted through education will likely be easily integrated into the existing knowledge systems.     

Circadiane Uhren und Energiemetabolismus

Chrononutrition – circadian clocks and energy metabolism Genetically encoded endogenous clocks regulate 24‐hour rhythms of physiology and behavior. A central pacemaker residing in the suprachiasmatic nucleus synchronizes peripheral clocks found in all tissues with each other and with the external day‐night cycle. One function of circadian clocks is the regulation of energy metabolism via rhythmic activation of tissue‐specific clock‐controlled genes. In the liver, genes involved in glucose and lipid metabolism are regulated in this fashion, while in adipocytes, fatty acid release and adipokine secretion are controlled by the circadian clock. Disruption of circadian rhythms as seen, for example, in shift workers promotes the development of metabolic disorders such as obesity and type‐2 diabetes.     

Oral health promotion among older persons and their care providers in a nursing home facility

Objectives: To assess oral health status and oral health‐related quality of life (OHRQoL) of residents in an extended care facility and to assess the care providers’ oral health attitudes and knowledge. Methods: Participants included 137 residents (58.1% female, age range 32–94 years, 91% African–American) and 22 care providers. Residents received an oral examination and completed the Oral Health Impact Profile (OHIP‐14), an OHRQoL questionnaire. Care providers completed an oral health knowledge (OHK) questionnaire before and after the on‐site geriatric oral health education and training programme. Results: Oral examinations showed that 58% of the residents had extensive oral health needs. On the OHIP‐14, the mean severity was 9.2 (SD = 12.0), extent (number of items rated as ‘fairly often’ or ‘often’) was 1.2 (SD = 2.6) and prevalence (participants rating at least one item at least ‘fairly often’) was 37.8%. Most prevalent negative impact items were about ‘oral pain’, ‘appearance’ and ‘self‐consciousness’. Regarding OHK, caregivers’ knowledge improved following instruction from 65% correct on the pre‐test to 90% correct on the post‐test (p < 0.05). Subsequent to the eight in‐service workshops, providers reported that physical limitations, fear of getting bitten and time constraints were barriers to providing oral hygiene to their residents. Conclusion: Examination data showed a high level of dental needs among the majority of residents, accompanied by significantly reduced OHRQoL. Although care providers’ OHK improved following the geriatric service programme, they reported specific barriers regarding their provision of oral hygiene care to the residents.     

The health status of Russian-speaking immigrants in Germany.

INTRODUCTION: Germany developed today into a country of immigration, which creates an additional burden for the social security system and results in a new challenge for the healthcare. In the last 17 years more than two million "Russia Germans" have been repatriated and about two hundred thousand Jewish refugees have resettled in Germany from the former Soviet Union. Nevertheless relevant data concerning migration-related public health care are very scare. METHODS: Search of PubMed and Journals extracts combined with the own researches, analysing the health status indices of the Russian-speaking immigrants in Germany. RESULTS: Both repatriates of German origin and Jewish refugees demonstrated higher prevalence of impaired lipid metabolism in comparison with native population. 42 % of the 503,040 HBsAg (hepatitis B s-Antigen) carriers in Germany were migrants. The Jewish refugees demonstrated the highest rates of depression and anxiety and the highest levels of awakening cortisol. On the other side German resettlers showed lower cardiovascular as well as all-cause death rates compared to the native Germans. CONCLUSION: The development of adequate health care programmes to address migratory aspects as well as the establishment of quality standards will realistically enhance the capability of responding rapidly to migrant health aspects and help to tackle inequalities in health.     

Natural regeneration in the context of large‐scale forest and landscape restoration in the tropics

Large‐scale and long‐term restoration efforts are urgently needed to reverse historical global trends of deforestation and forest degradation in the tropics. Restoration of forests within landscapes offers multiple social, economic, and environmental benefits that enhance lives of local people, mitigate effects of climate change, increase food security, and safeguard soil and water resources. Despite rapidly growing knowledge regarding the extent and feasibility of natural regeneration and the environmental and economic benefits of naturally regenerating forests in the tropics, tree planting remains the major focus of restoration programs. Natural regeneration is often ignored as a viable land‐use option. Here, we assemble a set of 16 original papers that provide an overview of the ecological, economic, and social dimensions of forest and landscape restoration (FLR), a relatively new approach to forest restoration that aims to regain ecological integrity and enhance human well‐being in deforested or degraded forest landscapes. The papers describe how spontaneous (passive) and assisted natural regeneration can contribute to achieving multiple social and ecological benefits. Forest and landscape restoration is centered on the people who live and work in the landscape and whose livelihoods will benefit and diversify through restoration activities inside and outside of farms. Given the scale of degraded forestland and the need to mitigate climate change and meet human development needs in the tropics, harnessing the potential of natural regeneration will play an essential role in achieving the ambitious goals that motivate global restoration initiatives.     

Health and cancer prevention: knowledge and beliefs of children and young people.

OBJECTIVE--To collect information from children and young people about their knowledge of and attitudes towards cancer and their understanding of health and health related behaviours to inform future health promotion work. DESIGN--Questionnaire survey of 15-16 year olds, and interviews with play materials with 9-10 year old children. SETTING--Six inner city, suburban, and rural schools. SUBJECTS--226 children aged 15-16 years and 100 aged 9-10 years. MAIN OUTCOME MEASURES--Knowledge about different types of cancer; beliefs about health; sources of information; quality of research data obtainable from young children about cancer and health. RESULTS--Both samples knew most about lung cancer, but there was also some knowledge of breast and skin cancer and leukaemia. Smoking, together with pollution and other environmental factors, were seen as the dominant causes of cancer. Environmental factors were mentioned more often by the inner city samples. Television and the media were the most important sources of information. Young people were more worried about unemployment than about ill health. More than half the young people did not describe their health as good, and most said they did not have a healthy lifestyle. Children were able to provide detailed information about their knowledge and understanding by using drawings as well as interviews. CONCLUSIONS--Children and young people possess considerable knowledge about cancer, especially about lung cancer and smoking, and show considerable awareness of predominant health education messages. Despite this knowledge, many lead less than healthy lifestyles. Health is not seen as the most important goal in life by many young people; the circumstances in which many children and young people live are not experienced as health promoting.     

Patterns of dental caries and treatment experience in elderly Lithuanians

Objective: The aim of the study was to evaluate patterns of caries experience in a representative sample of Lithuanians, aged 65‐74. Methods: This cross‐sectional study included 301 participants (response rate 54%). Information was obtained from a clinical examination (caries experience, stimulated salivary flow rates and oral hygiene levels) and a questionnaire. The questionnaire comprised questions about oral, general, physical, mental and social health and about background, knowledge, attitudes and lifestyle. The study had a multidimensional approach to negative consequences of disease and positive aspects of health. For bivariate testing, t‐test, ANOVA and Spearman's correlation were used. Factor analysis was combined with linear multiple regression for a multivariate study of caries experience patterns. Results: Elderly Lithuanians were found to have lower levels of edentulousness (range 11‐15%) than elderly people in other European countries. The mean number of missing teeth was also lower than in any of the neighbouring countries. A comparison of dentate and edentulous groups did not show any major differences. Those who reported that they had general disease had higher levels of oral health maintenance. In dentate elderly, caries experience differed according to place of residence, fluoride content in the drinking water, socio‐economic status, gender, lifestyle, and many other factors. The multivariate approach explained 52%. 61% and 55% of the variation in the number of filled or sound teeth (FS‐T), delayed (DT) and missing teeth (MT) respectively. Conclusion: Levels of oral health maintenance and caries experience show substantial variation among elderly Lithuanians, according to many health‐related characteristics. These elderly people require appropriate oral care, just as much as people in other population sub‐groups.     

Consensus statement understanding health and malnutrition through a systems approach: the ENOUGH program for early life

Nutrition research, like most biomedical disciplines, adopted and often uses experimental approaches based on Beadle and Tatum’s one gene—one polypeptide hypothesis, thereby reducing biological processes to single reactions or pathways. Systems thinking is needed to understand the complexity of health and disease processes requiring measurements of physiological processes, as well as environmental and social factors, which may alter the expression of genetic information. Analysis of physiological processes with omics technologies to assess systems’ responses has only become available over the past decade and remains costly. Studies of environmental and social conditions known to alter health are often not connected to biomedical research. While these facts are widely accepted, developing and conducting comprehensive research programs for health are often beyond financial and human resources of single research groups. We propose a new research program on essential nutrients for optimal underpinning of growth and health (ENOUGH) that will use systems approaches with more comprehensive measurements and biostatistical analysis of the many biological and environmental factors that influence undernutrition. Creating a knowledge base for nutrition and health is a necessary first step toward developing solutions targeted to different populations in diverse social and physical environments for the two billion undernourished people in developed and developing economies.     

Health ethics and Indigenous ethnocide

In colonial societies such as Canada the implications of colonialism and ethnocide (or cultural genocide) for ethical decision‐making are ill‐understood yet have profound implications in health ethics and other spheres. They combine to shape racism in health care in ways, sometimes obvious, more often subtle, that are inadequately understood and often wholly unnoticed. Along with overt experiences of interpersonal racism, Indigenous people with health care needs are confronted by systemic racism in the shaping of institutional structures, hospital policies and in resource allocation decisions. Above all, racism is a function of state law – of the unilateral imposition of the settler society law on Indigenous communities. Indeed, the laws, including health laws, are social determinants of the ill‐health of Indigenous peoples. This article describes the problem of Indigenous ethnocide and explores its ethical implications. It thereby problematizes the role of law in health ethics.     

The health of Indians in Canadian cities: a challenge to the health care system

It is well known that Canadian native people living on reserves have high morbidity and mortality rates, but less is known about the health of those who migrated to urban centres. Several studies have shown that these people have high rates of mental health problems, specific diseases, injuries, infant death and hospital admission. In addition, there is evidence that cultural differences create barriers to their use of health care facilities. The low socioeconomic status, cultural differences and discrimination that they find in cities are identified as the primary blocks to good health and adequate health care. More epidemiologic studies need to be done to identify health problems, needs and barriers to health care. Federal, provincial and civic governments along with the appropriate departments of faculties of medicine should begin working with native organizations to improve the health of native people living in Canada''s cities.     

Conjuring Medical Science: The 1986 Referendum on AIDS/HIV Policy in California

Medical science occupies a peculiar status in American life. On the one hand, people often view medical science as a privileged and authoritative body of knowledge that transcends other kinds of knowledge. On the other handy medical–scientific authority can be easily conjured from the popular symbols of science, e.g., credentials, technical terms, and white lab coats. This problem can be converted into an anthropological question of meanings and symbols, based on Geertz's interpretive anthropology and Baudrillard' s sociology of hyperreality. This article uses these frameworks to explore the cultural construction of medical-scientific authority in the case of a 1986 referendum on AIDS/HIV policy in California. The interpretation of that construction raises some difficult problems concerning anthropology's treatment of medical science.

Diversity of Plant Knowledge as an Adaptive Asset: A Case Study with Standing Rock Elders<Superscript>1</Superscript>

Diversity of Plant Knowledge as an Adaptive Asset: A Case Study with Standing Rock Elders. Indigenous knowledge is often represented as being homogeneous within cultural groups, and differences in knowledge within communities are interpreted as a lack of cultural consensus. Alternatively, differences in knowledge represent a range of possibilities for communities to respond to social and ecological change. This paper examines the diversity of plant knowledge among elders who live in the Standing Rock Nation of the northern Great Plains. Elders know how to use different plants, and also hold different knowledge about the same plants. Analysis indicates that elders each contribute unique, complementary, and seemingly contradictory plant knowledge to their community. Compiled seasonal rounds help visualize differences in knowledge about the temporal availability of plants. These differences are linked to variations in use, including references to specific gathering sites, strategies to harvest multiple species, and selection of plants at different stages of development. Elders’ diverse knowledge about the seasonal availability of plants may facilitate community adaptation to climate change in the 21st century.
