    Full Text Available Farm viability poses a grave challenge to the sustainability of agriculture and food systems: the number of acres in production continues to decline as the majority of farms earn negative net income. Two related and often overlapping marketing strategies, (i locally grown foods and (ii distribution at farmers markets, can directly enhance food system sustainability by improving farm profitability and long-term viability, as well as contributing to an array of ancillary benefits. We present results of a representative Michigan telephone survey, which measured consumers’ perceptions and behaviors around local foods and farmers markets. We discuss the implications of our findings on greater farm profitability. We conclude with suggestions for future research to enhance the contributions of locally grown foods and farmers markets to overall food system sustainability.

    Food choice is influenced by consumer attitudes towards food attributes. This U.S.-based study (n = 601) simultaneously compares attitudes towards selected food attributes of organic, locally grown, U.S. grown, and GM-free food in relation to other food attributes. Exploratory factor analysis identifies underlying constructs that determine, together and separately, female and male food choice decisions. Gendered analysis of the value of food in life and food behaviours (cooking and shopping) support the investigation of the highlighted food attributes. Respondents generally assigned greater importance to the U.S. grown, followed by GM-free, locally grown, and organically produced food attributes in deciding what to eat. Analysis of the female and male subsamples yielded similar factor results. All four main attributes were captured in a single factor, associated with respondents in both the female and male subsamples who are older, have lower incomes, and who are religiously observant. Additionally, among females, this factor was associated with higher education; and among males, living in households with children and/or with partners. Additional studies should further explore the interaction of food attributes now becoming increasingly important and prevalent in current food products. Copyright © 2010 Elsevier Ltd.

    The studies carried out by the Geographical Institute of Aix-en-Provence and the B.E.G.E.A. are in three forms: the first studies the local rural production (farming, animal rearing and fishing); the second is concerned with the food intake of the population within a radius of 5 to 10 km around the site; the third consists in working out a soil utilization map covering an area of about 2500 hectares around the site in order to determine the agricultural and urban areas as well as the open spaces, and the exact sort of cultivation carried out, plot by plot. The map also represents all the phenomena concerning hydrography, irrigation, watering and the supply of potable water. All these studies concern only a few parishes and enable an accurate knowledge of the environment to be acquired. The food studies seek an order of magnitude of the amount of local produce consumed by the populations of the nuclear power station sites with a view to determining radioactive contamination levels. The results show the specific food consumption features of a population bearing the deep stamp of its environment and its rural origin [fr

    Fallout deposition from the US nuclear weapons test program at Bikini and Enewetak Atolls (1946-1958) resulted in widespread nuclear fallout contamination of the northern Marshall Islands. About 85-90 % of the nuclear test-related dose delivered to resident populations is derived from ingestion of cesium-137 ( 137 Cs) contained in locally grown tree-crop food products. The Lawrence Livermore National Laboratory has developed a series of interactive internet applications to provide the public with an open access platform to learn more about radiological conditions in the Marshall Islands. The ingestion dose calculator application described here is one such feature whereby users can calculate hypothetical ingestion doses from 137 Cs based on interactive user input matched to environmental data on the activity concentration of 137 Cs contained in food plants such as coconut, breadfruit, Pandanus, and arrowroot. Users are asked to enter a date, an island and atoll location, a plant food type, and a daily intake amount (highlighted by the number of portions eaten per day in estimated gram equivalents). The application computes the user daily dose and the user equivalent annualized dose, and then compares the results with default settings based on dietary models developed for the Marshall Islands from independent dietary surveys. The default diets are based on a local plus imported food diet (or IA diet model) and an imported foods unavailable diet (or IUA diet model). Environmental data are decay corrected to the date entered by the user using an effective half-life of 137 Cs of 8.5 years (http://marshallislands.llnl.gov). (author)

  12. Localized Agri-Food Systems and Biodiversity

    Directory of Open Access Journals (Sweden)

    2018-02-01

    Full Text Available Interest in localized agri-food systems has grown significantly in recent years. They are associated with several benefits and are seen as important for rural development. An important share of the academic debate addresses the contribution of localized food systems to the current and/or future sustainability of agriculture. Sustainability is defined in several ways, but many scholars recognize that sustainability can only be achieved by a combination of socio-economic, cultural, and environmental aspects. However, the attributes and indicators used for sustainability analyses also differ. Biodiversity is, for instance, often not included in analyses of environmental sustainability even if biodiversity is of crucial importance for longer-term ecological sustainability. To contribute to the debate about the importance of localized food production for sustainability from the environmental point of view, specifically with regard to biodiversity, this is therefore discussed based on the results of several studies presented in this paper. The studies focus on Nordic low-intensity livestock systems related to species-rich semi-natural grasslands. All the studies show that low-intensive agriculture and use of semi-natural grasslands may play an important role in maintaining biodiversity on both small and large scales. They also show that milk and dairy products from free-ranging livestock in heterogeneous landscapes with semi-natural grasslands may have a unique quality associated with local grazing resources. Thus, producers can combine production of food of documented high nutritional and gastronomic value with maintenance of biodiversity, i.e., localized agri-food production based on low-intensive agriculture systems and semi-natural grasslands may be a win-win recipe for both farmers and the society.

  13. Weak localization behavior observed in graphene grown on germanium substrate

    2018-04-01

    Full Text Available Two dimensional electron systems (2DES usually show the weak localization behavior in consequence of electron interaction in the limited dimension. Distinct from other 2DES, the monolayer graphene, due to the chirality, exhibits unique weak localization behavior sensitive to not only inelastic but also elastic carrier scattering. Grain boundaries, which usually exist in monolayer graphene, are apparently related to the elastic carrier scattering process, thus affecting the weak localization behavior. However, their effect is scarcely studied due to the lack of an ideal platform. Here, a complementary system consisting of both single-crystalline graphene grown on Ge (110 and poly-crystalline graphene grown on Ge (111 is constructed. From the comparison of magnetoresistivity measurements, the weak localization effect is found to be greatly enhanced for the poly-crystalline graphene on Ge(111 compared to the single-crystalline graphene on Ge(110. The degraded transport performance in graphene/Ge(111 is due to the presence of grain boundary in poly-crystalline graphene, which results in the enhanced elastic intervalley scattering. In addition, the inelastic scattering originating from the strong electron-electron interaction at low temperature also contributes to weak localization of poly-crystalline graphene/Ge(111.

    Although much is understood about barriers to healthy food consumption in low-income, urban communities, knowledge regarding the crucial next step of building feasible, community-supported approaches to address those barriers remains limited. This qualitative study used in-depth interviews (n = 20), focus groups (n = 2), and participant observations (n = 3) to identify strategies to promote locally grown produce from an urban food security project, Produce From the Park (PFP), an urban farm. Informants included community organization representatives and residents from low-income neighborhoods in a mid-Atlantic city. Informants identified structural and cultural barriers to purchasing healthy food, including price, location, food culture, and lack of interest. Participants proposed a number of strategies, such as distribution through mobile food carts and farm stands, marketing new foods through taste tests and cooking demonstrations, and youth mentorship. Informants also described their perceptions of the local urban farm and suggested ways to increase community buy-in. Strategies mentioned were inexpensive and incorporated cultural norms and local assets. These community perspectives can provide insights for those promoting healthy eating in urban African American communities through urban food security projects.

  15. A moveable feast: Contemporary relational food cultures emerging from local food networks.

    O'Kane, Gabrielle

    2016-10-01

    Although the globalised food system delivers unparalleled food variety and quantity to most in the developed world it also disconnects consumers from where, how and by whom food is grown. This change in the food system has resulted in an acceptance of an anonymous and homogeneous food supply, which has contributed to over-consumption and the rise in diet-related diseases. 'Nutritionism' responds to this issue by maintaining that a 'healthy diet' can be achieved by consuming the correct balance of energy and nutrients, but with limited success. Yet, some food cultures can moderate the effects of the environmental drivers of increasing global obesity rates. This paper draws on this premise and presents an alternative eco-dietetic response, exploring people's meaning-making of food and food culture through local food networks. This research used narrative inquiry methodology and purposive sampling to gather stories through focus group conversations. Twenty people attended focus groups comprised of food procurers from one of three local food networks in the Canberra region: community gardens, a modified Community Supported Agriculture (CSA) and farmers' markets. The findings showed that those using local food networks enjoyed a 'contemporary relational food culture' that highlighted the importance of people, place and time, in their visceral experiences of food. The community gardeners made meaning of food through their connections to the earth and to others. The farmers' market and CSA food procurers valued the seasonal, local and ethical food produced by their beloved farmer(s). This paper provides qualitative evidence that local food networks enable people to enjoy multi-dimensional relationships to food. Further research is required to examine whether experiencing a contemporary relational food culture can lead to improved health outcomes for people and the planet. Copyright © 2016 Elsevier Ltd.

    Steve W. Martinez

    2016-08-01

    Full Text Available Local food has been the subject of federal, state, and local government policies in recent years throughout the United States as consumer demand has grown. Local foods have been linked to several government priorities—including enhancing the rural economy, the environment, and supporting agricultural producers. This article provides an overview of U.S. Federal, State and regional policies designed to support local food systems. It details the latest economic information on policy, relying on findings from several national surveys and a synthesis of recent literature. Federal policies related to local food systems were greatly expanded by the 2008 Farm Bill, and are further expanded in the Agricultural Act of 2014. United States policies address several barriers to the further expansion of local food markets, including scaling up output of small farms to address the needs of larger commercial outlets, lack of infrastructure for increasing local food sales, ability to trace product source, and producer education regarding local food expansion.

    Insects have played an important role as human food throughout history, especially in Africa, Asia and Latin America. A good example of edible insects is the mealworm, Tenebrio molitor Linnaeus, 1758 (Coleoptera, Tenebrionidae), which are eaten in Africa, Asia, the Americas and Australia. This species is easily bred in captivity, requiring simple management. The bocaiuva (Acrocomia aculeata (Jacq.) Lodd) is an abundant palm tree found in the Brazilian Cerrado, providing fruits with high nutritional value. The aim of this work was to determine the chemical composition of T. molitor grown in different artificial diets with bocaiuva pulp flour. The nutritional composition, fatty acid composition, antioxidant activity, trypsin activity and anti-nutritional factors of larvae were analyzed. The results showed that mealworms grown on artificial diet with bocaiuva are a good source of protein (44.83%) and lipid (40.45%), with significant levels of unsaturated fatty acids (65.99%), antioxidant activity (4.5 μM Trolox/g of oil extracted from larvae) and absence of anti-nutritional factors. This study indicates a new source of biomass for growing mealworms and shows that it is possible to breed mealworms in artificial diet with bocaiuva flour without compromising the nutritional quality of the larvae.

    Full Text Available Malnutrition and lack of economic sustainability are major problems in developing countries. This study was conducted to evaluate and compare the nutrients‘ contents of three locally grown nuts in Nigeria (local groundnut, Kampala groundnut and breadnut and highlight their health and economic potentials. Proximate analysis, chemical properties, minerals and fatty acids composition of the nuts were determined. The highest protein, crude fibre and carbohydrate contents were found in Kampala groundnut, local groundnut and breadnut respectively. Their sodium-potassium ratios were all less than 1.0 and their oils have mainly unsaturated fatty acids. Their acid values ranged between (2.41–6.34 mgKOH/g while the iodine values were between 36.0 and 93.0 I2 g/100 g. Analysis of the nuts and their oils indicated that they could help in solving malnutrition problem and also boost nations’ economy. Encouraging their large scale production can enhance adequate nutrition and sustain industrial growth in developing countries. Keywords: Nutrition, Food analysis, Food science

    Full Text Available The aim of this study was to evaluate the influence of the grown locality on minerals and risky metal intake from the soil and on polyphenols formation in the soybean seeds. The research was realised in five localities of Slovakia using the seven soybean varieties. From the point of the soil hygiene, all determined values of heavy metals content in soils were lower than given hygienic limits, with the exception of Cd. Minerals and heavy metals contents in the soybean samples show significant differences between cultivars and localities. The values show imbalance between the potassium contents and other minerals. The order of the elements levels was determined as following: Fe > Zn > Mn > Cu > Ni > Pb > Cr ≈ Co > Cd. The risky elements contents, with exception of Cd, Cu, Pb and Ni content (only in some localities, did not exceed a limit for legumes by Food Codex SR. The total polyphenols content ranged from 817.6 to 1281.0 μg eq. tannic acid/g and suggest the variety dependence, but the locality influence was not significantly confirmed.

    Variations of the lattice parameter can significantly change the properties of a material, and, in particular, its electronic behaviour. In the case of graphene, however, variations of the lattice constant with respect to graphite have been limited to less than 2.5% due to its well-established high in-plane stiffness. Here, through systematic electronic and lattice structure studies, we report regions where the lattice constant of graphene monolayers grown on copper by chemical vapour deposition increases up to 7.5% of its relaxed value. Density functional theory calculations confirm that this expanded phase is energetically metastable and driven by the enhanced interaction between the substrate and the graphene adlayer. We also prove that this phase possesses distinctive chemical and electronic properties. The inherent phase complexity of graphene grown on copper foils revealed in this study may inspire the investigation of possible metastable phases in other seemingly simple heterostructure systems.

    Algae have an ample potential to produce biodiesel from spent wash of food industry. In addition, it is cheaper and presents an environment friendly way to handle food industry wastewater. This study was conducted to optimize the growth of microalgal strains and to assess biodiesel production potential of algae using untreated food industry wastewater as a source of nutrients. The food industry wastewater was collected and analyzed for its physicochemical characteristics. Different dilutions (10, 20, 40, 80, and 100%) of this wastewater were made with distilled water, and growth of two microalgal strains (Cladophora sp. and Spyrogyra sp.) was recorded. Each type of wastewater was inoculated with microalgae, and biomass was harvested after 7 days. The growth of both strains was also evaluated at varying temperatures, pH and light periods to optimize the algal growth for enhanced biodiesel production. After optimization, biodiesel production by Spyrogyra sp. was recorded in real food industry wastewater. The algal biomass increased with increasing level of food industry wastewater and was at maximum with 100% wastewater. Moreover, statistically similar results were found with algal growth on 100% wastewater and also on Bristol's media. The Cladophora sp. produced higher biomass than Spyrogyra sp. while growing on food industry wastewater. The optimal growth of both microalgal strains was observed at temperature 30 °C, pH: 8, light 24 h. Cladophora sp. was further evaluated for biodiesel production while growing on 100% wastewater and found that this strain produced high level of oil and biodiesel. Algae have an ample potential to produce biodiesel from spent wash of food industry. In addition, it is cheaper and presents an environment friendly way to handle food industry wastewater.

  10. Receiving Assistance and Local Food System Participation

    Directory of Open Access Journals (Sweden)

    Rebecca L. Som Castellano

    2017-02-01

    Full Text Available A body of literature has noted that local food systems (LFSs may not involve active participation by individuals with lower incomes. This is, in part, a function of racial and class hegemony, as well as physical and financial accessibility of LFSs. LFS institutions, such as farmers’ markets, have been working to facilitate receipt of food assistance programs, such as the Supplemental Nutrition Assistance Program (SNAP. Charitable assistance programs, such as food banks, have also been actively working to engage in LFSs, for example, by making local foods available. However, little research has explored the role that receiving public or charitable assistance can play in influencing LFS participation. In this article, I utilize quantitative and qualitative data collected from across the state of Ohio to examine the relationship between receiving assistance and LFS participation for women, who remain predominately responsible for food provisioning in the U.S., including among those who participate in LFSs. Quantitative results suggest that receiving assistance can increase participation in LFSs. Qualitative data provides more nuanced information about the importance of food assistance for women who want to participate in LFSs, and suggest that it is essential that food cooperatives and farmers’ markets are equipped to receive food assistance programs, such as SNAP, in order for women with lower incomes to participate in LFSs.

    Full Text Available Introduction: Fluorine is the 13th most abundant element in the earth crust and is available in various environmental, clinical, and food samples in varied concentrations. Aim: To estimate concentration of fluoride in five medicinal and five nonmedicinal edible leaves locally grown around Raipur, Chhattisgarh, India. Materials and Methods: Samples of ten medicinal and nonmedicinal edible leaves, namely, spinach (Spinacia oleracea, coriander leaves (Coriandrum sativum, chawli bhaji (Amaranthus spinach, lal bhaji (Alternanthera bettzickiana, mooli bhaji (Raphanus sativus, neem (Azadirachta indica, tulsi (Ocimum tenuiflorum, mint leaves (Mentha longifolia, betel leaves (Piper betle, and bael leaves (Aegle marmelos were collected in the clean polyethene bags. After thorough washing with water, leaves were left to dry in ambient temperature and crushed into powder using a mixer grinder. One gram of each of the powdered samples was taken and analyzed for fluoride concentration using a 2-(4-sulfophenylazo 1,8-dihydroxy-3,6-naphthalenedisulfonic acid trisodium salt spectrophotometric method. Results: The presence of fluoride in varied concentrations in locally grown edible leaves were analyzed. The highest concentration of fluoride was reported in tulsi (6.0 μg/g and lowest in mint leaves (1.1 μg/g. Two edible leaves, neem and bael, showed fluoride concentration below detection limit. Conclusion: Knowledge regarding the importance of edible leaves may be lost in the near future unless efforts are made to educate younger generations about their importance. Hence, the time has come to make good use of centuries-old knowledge through modern approaches for their better economic and therapeutic utilization.

    Appropriate complementary food is a must for optimum growth of infants and children. The food should be diverse and be given in sufficient quantities 2-4 times a day depending upon age. Poverty, food insecurity, and lack of awareness regarding the choice of nutritious food ingredients are deterrents to optimum complementary feeding. In Bangladesh, 77% of children do not receive appropriate complementary food and, hence, the high prevalence of childhood malnutrition. We developed ready-to-use complementary foods (RUCFs) using locally available food ingredients, rice/lentil and chickpea, which conform to standard specifications. These foods were found to be acceptable by children and their mothers compared to the Pushti packet, the cereal-based supplement used in the erstwhile National Nutrition Program of Bangladesh. In a cluster-randomized community-based trial in rural Bangladesh among more than 5,000 children, the efficacy of rice/lentil- and chickpea-based RUCFs was compared with another commonly used supplementary food called wheat-soy blend++ (WSB++) and a commercial product called Plumpy'doz. Deceleration in length for age was significantly lower (by 0.02-0.04/month) in the rice/lentil, Plumpy'doz, and chickpea groups compared to the control group at 18 months of age. Weight-for-length z-score decline was lower only in Plumpy'doz and chickpea groups. WSB++ was not different from the control group. In children who received chickpea RUCF or Plumpy'doz, the prevalence of stunting was 5-6% lower at 18 months. These foods can be used to prevent or treat malnutrition among children, particularly those from food-insecure households. © 2017 Nestec Ltd., Vevey/S. Karger AG, Basel.

    Increased production and consumption of local food may reduce the negative environmental, social, and economic impacts of industrialized and globalized food production. Here we examined potential barriers to increasing production and consumption of food produced in Iceland. First, we developed a new framework to address the behaviors of production and consumption simultaneously, to comprehensively analyze their potential barriers. We examined structural barriers by estimating the food production capacity of Iceland, and cultural and personal barriers through survey data on cultural norms and purchasing behavior from Matís, a research and development company. We found no structural barriers preventing Iceland from increasing production of local cereals, which would compliment current local production of meat and dairy and reduce reliance on imports, currently at 50% of the daily caloric intake. However, if food production became entirely local without changing the current mix of crops grown, there would be a 50% reduction in diversity (from 50 to 25 items in eight out of ten food categories). We did not identify any cultural barriers, as survey results demonstrated that consumers hold generally positive worldviews towards local food, with 88% satisfied with local food they had purchased. More than two-thirds of consumers regarded supporting the local farmer and considerations such as environmentally friendly production, fewer food miles, lower carbon footprint as important. However, they rated the local food they have access to as lower in meeting sustainability criteria, showing that they make justifications for not choosing local food in practice. This is a personal barrier to increased consumption of local food, and implies that marketing strategies and general knowledge connected to local food in Iceland might be improved. Although the results apply to the case of Iceland, the method of identifying behavioral barriers to change is applicable to other countries

    The Hunger Prevention and Nutrition Assistance Program (HPNAP) is a New York State Department of Health program. The HPNAP improves nutritional quality of food available at food banks, food pantries, soup kitchens, and emergency shelters through contractual relationships to fund the purchase, delivery, storage, and service of nutritious food. To determine whether a one-time fiscal stimulus of the Locally Grown Produce Initiative to HPNAP contractors in 2012-2013 would result in a short-term sustainable increase in the proportion of dollars spent on New York State Grown (NYSG) produce. Quasi-experimental, nonequivalent control group design. We analyzed New York State Department of Health administrative data regarding expenditures on all produce and NYSG produce by HPNAP contractors. New York State. The proportion of dollars spent on NYSG produce during 2011-2012 (preintervention) and 2013-2014 (postintervention) was compared between HPNAP food bank contractors (recipients of stimulus money, n = 8) and non-food bank contractors (nonrecipients, n = 34) using nonparametric methods. The HPNAP Locally Grown Produce Initiative was associated with an increased proportion of NYSG produce spending by food bank contractors that received a fiscal stimulus 1 year later. Upstate food banks had the largest increase (median 31.6%) among all HPNAP contractors. The results of this study revealed that the Locally Grown Produce Initiative fiscal stimulus had a positive, year-long and statewide effect on the proportion of expenditure on NYSG produce by food banks. We hope that the initial success seen in New York State may encourage other states to adopt similar initiatives in future.

  18. Local food: benefits and failings due to modern agriculture

    Directory of Open Access Journals (Sweden)

    Fábio Cunha Coelho

    Full Text Available ABSTRACT: This paper aims to examine the issue raised by the consumption of locally produced food in all its various aspects, and in particular, addresses how this practice contributes to local and global sustainability. It analyzes the different definitions of local food, the strategies used, the implications of the distance traveled in the transportation of food to the consumer's table – food miles, the relationships between local food consumption and sustainability, farming practices that reduce carbon emissions, contribution of urban agriculture to local food, local trading of food produced by rural farmers, as well as a number of relationships between the consumption of local food and human nutrition and health, local food protection and the ability to support local food production for humanitarian actions in disaster situations. The promotion of “local food” is a complex problem covering environmental issues, the economy and health. Transportation is not the only factor that determines how efficient it is to consume local food. Often, the technologies used for agricultural production are those most responsible for the degree of sustainability in the production and supply of food to the population. Local production does not always mean lower emissions of greenhouse gases. In general, the consumption of local foods, produced in ways adapted to the local environment using technologies with an ecological basis, is something beneficial and salutary for the environment, economy and society in general.

    2014-11-01

    Full Text Available It is observed that quality of mass produced and highly processed food forces consumers to change their consumption habits and become more interested in locally available food products. Consumers are becoming aware of negative consequences of global food systems. As an alternative, Local Food Systems are gaining on popularity because short food supply chains offer fresh, healthy and not modified products. The popularity of Local Food Systems is reflected in the need for analysing impact and significance of those systems. Thus, this paper presents main benefits of acting locally. Local Food Systems has been reviewed in case of positive economic, environmental and social influence on the region. What is more, the paper presents consumers’ attitude to Local Food Systems. As a conclusion authors justify significance of development and investment in Local Food Systems as an alternative to agriculture networks.

    The local electrical properties of thermally grown oxide films formed on ferrite and austenite surfaces of duplex stainless steel at different temperatures were investigated by Current sensing atomic force microscopy, X-ray Photoelectron Spectroscopy (XPS) and Auger Electron Spectroscopy (AES). The current maps and XPS/AES analyses show that the oxide films covering austenite and ferrite surfaces formed at different temperatures exhibit different local electrical characteristics, thickness and composition. The dependence of electrical conductivity of oxide films covering austenite and ferrite surface on the formation temperature is attributed to the film thickness and semiconducting structures, which is intrinsically related to thermodynamics and kinetics process of film grown at different temperature. This is well elucidated by corresponding semiconductor band structures of oxide films formed on austenite and ferrite phases at different temperature.

    This communication gives an overview of selected isotope analyses applied to food authenticity assessment. Different isotope ratio detection technologies such as isotope ratio mass spectrometry (IRMS) and cavity ring down spectroscopy (CRDS) are briefly described. It will be explained how δ(18)O of water contained in fruits and vegetables can be used to assess their country of production. It will be explained why asparagus grown in Valais, in the centre of the Alps carries much less heavy water than asparagus grown closer to the sea coast. On the other hand, the use of δ(13)C can reveal whether a product is natural or adulterated. Applications including honey or sparkling wine adulteration detection will be briefly presented.

    Full Text Available Local food producers are often advised to collaborate with other local food producers to jointly participate in marketing and sales activities. Local food producers are often small and must operate many different activities to run their company, so the idea to collaborate may help them to become more efficient. We explore the role of marketing in local food networks through an analysis of marketing strategies and marketing mix in six local food networks in central Norway. When producers participate in food networks, they disconnect from direct relationships with their consumers. The value of this relationship must be considered in addition to costs related to sales and distribution in the network. The networks rely on regional products and regional branding as the main marketing strategy and promote local and localized products.

    2014-05-01

    Full Text Available Lake water temperature is negatively correlated with fatty acids content and P:C ratio in green algae. Hence, elevated temperature may indirectly reduce the fitness of Daphnia due to induced decrease in algal food quality. The aim of this study was to test the hypotheses that quality of algal food decreases with increasing temperature of its culture and that large-bodied Daphnia are more vulnerable to the temperature-related deterioration of algal food quality than small-bodied ones. Laboratory life-table experiments were performed at 20°C with large-bodied D. pulicaria and small-bodied D. cucullata fed with the green alga Scenedesmus obliquus, that had been grown at temperatures of 16, 24 or 32°C. The somatic growth rates of both species decreased significantly with increasing algal culture temperature and this effect was more pronounced in D. pulicaria than in D. cucullata. In the former species, age at first reproduction significantly increased and clutch size significantly decreased with increasing temperature of algae growth, while no significant changes in these two parameters were observed in the latter species. The proportion of egg-bearing females decreased with increasing algal culture temperature in both species. The results of this study support the notion that the quality of algal food decreases with increasing water temperature and also suggest that small-bodied Daphnia species might be less vulnerable to temperature-related decreases in algal food quality than large-bodied ones.

    Full Text Available Abstract Consumers have rights which should not just be ignored by businesses such as the right to be a safety the right be informed the right to be heard as well as the right to a good environment and healthy. Kendari Regency as a local government has been manifested by issuing regulations and policies that support the development of local food production such as the Mayor of Kendari regulation No. 15 of 2010 and Mayor Kendari Decree No. 427 of 2012 regarding the Establishment of Community Care Local Food. It appears that the local government is trying to make this local food as an alternative food. The type of research used in this paper is a socio-legal research reviewing the local food production from the perspective of consumer protection. The outcomes of the research indicate that responsibility of food business operators in the implementation of local production is essentially an effort to assist the government in ensuring the realization of food safety system. Therefore there is a need for awareness of the laws and regulations for all parties involved towards local food production especially in Kendari Regency Southeast Sulawesi on the food production process.

  15. Association between fast food purchasing and the local food environment.

    Thornton, Lukar E; Kavanagh, A M

    2012-12-03

    In this study, an instrument was created to measure the healthy and unhealthy characteristics of food environments and investigate associations between the whole of the food environment and fast food consumption. In consultation with other academic researchers in this field, food stores were categorised to either healthy or unhealthy and weighted (between +10 and -10) by their likely contribution to healthy/unhealthy eating practices. A healthy and unhealthy food environment score (FES) was created using these weightings. Using a cross-sectional study design, multilevel multinomial regression was used to estimate the effects of the whole food environment on the fast food purchasing habits of 2547 individuals. Respondents in areas with the highest tertile of the healthy FES had a lower likelihood of purchasing fast food both infrequently and frequently compared with respondents who never purchased, however only infrequent purchasing remained significant when simultaneously modelled with the unhealthy FES (odds ratio (OR) 0.52; 95% confidence interval (CI) 0.32-0.83). Although a lower likelihood of frequent fast food purchasing was also associated with living in the highest tertile of the unhealthy FES, no association remained once the healthy FES was included in the models. In our binary models, respondents living in areas with a higher unhealthy FES than healthy FES were more likely to purchase fast food infrequently (OR 1.35; 95% CI 1.00-1.82) however no association was found for frequent purchasing. Our study provides some evidence to suggest that healthier food environments may discourage fast food purchasing.

    Sandy soils of the coastal plain area of Western Australia have poor phosphorous retention capacity which leads to pollution of surface water bodies in the region. Application of bauxite mining residues (termed 'red mud') to vegetable and crops has been proposed as a solution to increase the phosphorous and water retention and thereby reduce the leaching of nutrients. The thorium and radium-226 concentrations in the 'red mud' residues are in excess of 1 kBq/kg, and 300 Bq/kg respectively. Potentially, the use of these residues on agricultural land could result in increased levels of radionuclides in food grown in amended soils. The transfer of long-lived radionuclides of both the natural thorium and uranium series to a variety of vegetable crops grown under controlled conditions is investigated. The effects of varying the rates of application of 'red mud' and phosphate fertilizers on radionuclide uptake are studied. It has been shown previously that fallout caesium-137 is sandy soils of the region transfers readily to food and grazing crops. Some of the parameters which influence that transfer are also examined.

  17. Does eating local food reduce the environmental impact of food production and enhance consumer health?

    Science.gov (United States)

    Edwards-Jones, Gareth

    2010-11-01

    The concept of local food has gained traction in the media, engaged consumers and offered farmers a new marketing tool. Positive claims about the benefits of local food are probably not harmful when made by small-scale producers at the local level; however, greater concern would arise should such claims be echoed in policy circles. This review examines the evidence base supporting claims about the environmental and health benefits of local food. The results do not offer any support for claims that local food is universally superior to non-local food in terms of its impact on the climate or the health of consumers. Indeed several examples are presented that demonstrate that local food can on occasions be inferior to non-local food. The analysis also considers the impact on greenhouse gas emissions of moving the UK towards self-sufficiency. Quantitative evidence is absent on the changes in overall emissions that would occur if the UK switched to self-sufficiency. A qualitative assessment suggests the emissions per item of food would probably be greater under a scenario of self-sufficiency than under the current food system. The review does not identify any generalisable or systematic benefits to the environment or human health that arise from the consumption of local food in preference to non-local food.

  18. Developing Exchange in Short Local Foods Supply Chains

    Directory of Open Access Journals (Sweden)

    Per Engelseth

    2016-07-01

    Full Text Available The supply chain management of foods is commonly associated with modernistic large-scale production. This involves long transport distances of foods to reach consumers. In the case of local foods, supply chains are shorter. Based on a case study of five local foods producer's supply of their products to a common retailer, the supply chain of local foods is modelled conceptually and modes of development are pointed out based on contingency theory and supply chain management literature. Findings reveal that since these chains are transparent, reciprocal interdependency is abundant mainly because human perception creates a sufficient understanding of the operations management issues pertinent within this simple inter-organisational structure. Local foods supply chains are similar to service supply chains. This includes that both are short in nature and associated with bi-directional interaction between the customer and supplier. Developing short supply chains in local foods supply is associated with improving the exchange economy found in short supply chains. This also implies that development of local foods supply is associated with two paths which may be complementary. First, the use of improved intensive technology associated with reciprocal interdependency to develop efficiencies in the bi-directional and somewhat complex interaction. Alternatively local foods suppliers may seek to reduce this form of reciprocal interdependency thereby increasing the impact of pooled interdependencies and enabling using mediating technology involving standardising interaction such as through increased standardised products and packaging as well as automation of information connectivity.

  19. How important is local food to organic-minded consumers?

    Hempel, Corinna; Hamm, Ulrich

    2016-01-01

    The study deals with German consumers' attitudes towards organic food and local food, their food purchase behaviour and their personal characteristics. The purpose is to investigate the differences in attitudes and willingness-to-pay values between consumers who consider the organic production of food (very) important and those who consider it less important. This study combines a consumer survey with an in-store, discrete choice experiment. In the analysis, findings from the consumer survey were related to the choices made by consumers in the experiment. Consumers' preferences and willingness-to-pay values were estimated through random parameter logit modelling. Organic-minded consumers (i.e. those who regarded organic food production as (very) important in the survey) have stronger preferences and estimated willingness-to-pay values for organic as well as local products. Locally produced food, as opposed to food from neighbouring countries or non-EU countries, is preferred over organically produced food by both consumer groups which demonstrates that organic-minded consumers do not only consider organic food production as important, but also value local food production in a purchase situation. Hence, it can be assumed that local food production complements organic food production for the group of organic-minded consumers. This contribution is the first study dealing with local and organic food purchase behaviour in Germany that examines four different products and is carried out in rural as well as urban locations in four different regions. Due to the application of a choice experiment including no-choice options and binding purchase decisions, the results are expected to be closer to real purchase situations than results of direct questioning and choice experiments in online applications.

  20. The case for local food in sustainable food-energy-water systems

    Science.gov (United States)

    Campbell, J. E.; Zumkehr, A. L.; Yang, Y.

    2017-12-01

    Local food systems, which are characterized by foodsheds with small distances between production and consumption ( 100 km), are currently experiencing explosive growth. Local food has largely been assessed within the context of transportation energy. While the effects of local food systems on transportation energy are well studied, broader implications of localization on the food-energy-water nexus are not. Furthermore, little is known about the potential for local food to scale beyond niche markets and meet a significant fraction of total food demand. Here we estimate the upper potential for all existing croplands to meet total U.S. food demand through local food networks. Our spatially explicit land-use model simulates the years 1850 through 2000 and accounts for a wide range of foodshed areas, diets, food waste, population distributions, cropland areas, and crop yields. While we find that the foodshed potential has declined in time, our results also demonstrate an unexpectedly large potential at present for supporting as much as 82% of national food demand within a 50 mile foodshed radius. The decline is associated with extreme pressures from demographic and agronomic trends that if continued could significantly undermine recent national policies focused on food localization. We then apply a life-cycle assessment approach to show that for some crops, irrigation could contribute up to 50% of the cradle-to-gate carbon emissions, thus they may benefit from food localization making use of water from wastewater treatment plants. Our results also show that local food could reduce the water footprint of lettuce by 50%. Our study suggests that exploring future scenarios, beyond assessing historical outcomes, is critical if food-energy-water research is to support sustainable decision making.

    2012-01-01

    In many poor, food insecure regions, agriculture is a primary source of income and farmers are reliant both on their own production and on purchasing food in the market to feed their families. Large local food price increases over a short time period can be indicative of a deteriorating food security situation and may be the consequence of weather-related food production declines, Dr can simply be the result of price transmission from the international commodity market. Food price indices developed by the United Nations Food and Agriculture Organization (FAO) are used to monitor food price trends at a global level, but largely reflect supply and demand conditions in export markets far from the places where the chronically food insecure live. A much better understanding of how local staple food prices in isolated regions such as West Africa that grow most of the food they eat to better understand the impact of global commodity market transformations on sensitive communities at the margin. This information will also enable improved strategies for these farmers who are extraordinarily sensitive to climate change impacts on agricultural growing conditions.

    The Federated States of Micronesia (FSM) and other countries throughout the Pacific are facing an epidemic of non-communicable disease health problems. These are directly related to the increased consumption of unhealthy imported processed foods, the neglect of traditional food systems, and lifestyle changes, including decreased physical activity. The FSM faces the double burden of malnutrition with both non-communicable diseases and micronutrient deficiencies, including vitamin A deficiency and anemia. To help increase the use of traditional island foods and improve health, the Island Food Community of Pohnpei has initiated a program in the FSM to support and promote local food policies, along with its Go Local awareness campaign. Such local food policies are defined broadly and include individual and family commitments, community group local food policies and policies established by government, including presidential proclamations and increased taxation on soft drinks. The aim of this paper is to describe this work. An inter-agency, community- and research-based, participatory and media approach was used. Partners are both non-governmental and governmental. The use of continuing awareness work along with local food policy establishment and the acknowledgement of the individuals and groups involved are essential. The work is still in the preliminary stage but ad hoc examples show that this approach has had success in increased awareness on health issues and improving dietary intake on both an individual and group basis. This indicates that further use of local food policies could have an instrumental impact in FSM as well as other Pacific Island countries in promoting local foods and improving dietary intake and health, including the control of non-communicable diseases and other dietary-related health problems.

    Full Text Available L’intérêt pour une économie alimentaire alternative est de plus en plus marqué depuis une dizaine d’années. Le développement parallèle de travaux académiques et d’activités administrées par des organisations gouvernementales ou non-gouvernementales, conduit à un amalgame de théories et de pratiques diverses en matière de produits locaux. L’objectif de cet article est d’explorer les réseaux et les discours consernant la production et la consommation de produits locaux en Grande-Bretagne. L’analyse, entre autre fondée sur des interviews approfondies avec des représentants de l’industrie agro-alimentaire et d’organisations de base, révèle des differences dans le language et la conceptualisation du “local” qui influencent le rôle joué par les produits locaux aux niveaux économique et diététique. L’article s’achève sur l’importance et la priorité à donner aux politiques du secteur publique qui soutiennent les producteurs et entreprises de produits locaux, à la fois en milieu rural et urbain.Interest in an alternative food economy has been growing over the last decade. Parallel developments in academia and the activities of government and non-government organisations have led to a fusion of theory and practice under an umbrella of local food. The purpose of this article is to explore the networks and discourses that surround the production and consumption of local food in the UK. This is achieved through the analysis of a series of in-depth interviews with industry and grassroots organisations set against a background of consumer opinion deriving from focus groups. The analysis demonstrates that differences in the language and conceptualisation of local reveal different roles for local food in the economy and in the diet. The article concludes that policies to support public sector procurement through a hinterland of small-scale producer marketing and processing enterprises should be a priority in

    The aim of this study was to investigate whether food freshness and locality can be classified using a food evaluation system consisting four SnO2-semiconductor gas sensors and a solid phase column, into which collecting aroma materials. The temperature of sensors was periodically changed to be in unsteady state and thus, the sensor information was increased. The parameters (in quefrency band) were extracted from sensor information using cepstrum analysis that enable to separate superimposed information on sinusoidal wave. The quefrency was used as parameters for principal component and discriminant analyses (PCA and DCA) to detect food freshness and food localities. We used three kinds of strawberries, people can perceive its odors, passed from one to three days after harvest, and kelps and Ceylon tea, people are hardly to perceive its odor, corrected from five areas as sample. Then, the deterioration of strawberries and localities of kelps and Ceylon teas were visually evaluated using the numerical analyses. While the deteriorations were classified using PCA or DCA, the localities were classified only by DCA. The findings indicate that, although odorant intensity influenced the method detecting food quality, the quefrency obtained from odorant information using cepstrum analysis were available to detect the difference in the freshness and the localities of foods.

    Full Text Available  The study explores local food as a marketing opportunity for small food producers and identifies barriers to development. Research was conducted primarily through depth interviews, supplemented by a survey of food marketing group members in North-West England. The results of this local study were consistent with national survey data showing increasing consumer interest in food provenance, traceability and support for the local economy. Lack of an official and recognised definition of the term "local food" hindered marketing. Restricted access to finance and the burden of regulations were identified as barriers. Further, small business success was subjective and difficult to identify, since goals may be based on sustaining a lifestyle rather than profit.

    2013-03-01

    Full Text Available This paper investigates the opportunities for farmers to produce for local consumers, based on a case study in the Dutch horticulture sector. Main requirements for the set-up of a local chain of supply chain actors are investigated. Producer requirements are added value, availability of time, infrastructure and training. Retailer requirements are quality of food, purchasing volumes, food safety, communication to consumers and traceability of products. For consumers taste/freshness, sustainability, health benefits and authenticity are important attributes of local foods. Based on literature review and interviews with stakeholders four possible strategies for local food chains are defined. The ‘keep it local’ strategy means that the local food supply chains will not make use of the current infrastructure of the marketing coop that acts as chain coordinator. Deliveries are directly between farmer and retail outlet. The local products - conventional supply chain strategy implies that current (non-local supply chains are used to distribute local products. The supply chain planning will be more complex since products need to be separated per grower and distributed to several local supermarkets. In the ‘enabling producers’ strategy the marketing coop/chain coordinator is going to enable its member producers to sell their products locally. The marketing coop can support producers in for instance, billing and payments, marketing, logistics. The fourth strategy aims at strengthening current consumer communication strategies. It is argued that connecting producers and consumers, regardless of where they live is advantageous.Conclusion is that strategy 3; ‘Enabling producers’, in combination with strategy 4; ‘Strengthening current consumer communication strategies’ are the most promising options in setting up local food supply chains. Strategies 1 and 2, where the marketing coop/chain coordinator itself takes on the challenge of setting up

    Systematic reviews investigating associations between objective measures of the food environment and dietary behaviours or health outcomes have not established a consistent evidence base. The present paper aims to synthesise qualitative evidence regarding the influence of local food environments on food and purchasing behaviours. A systematic review in the form of a qualitative thematic synthesis. Urban localities. Adults. Four analytic themes were identified from the review including community and consumer nutrition environments, other environmental factors and individual coping strategies for shopping and purchasing decisions. Availability, accessibility and affordability were consistently identified as key determinants of store choice and purchasing behaviours that often result in less healthy food choices within community nutrition environments. Food availability, quality and food store characteristics within consumer nutrition environments also greatly influenced in-store purchases. Individuals used a range of coping strategies in both the community and consumer nutrition environments to make optimal purchasing decisions, often within the context of financial constraints. Findings from the current review add depth and scope to quantitative literature and can guide ongoing theory, interventions and policy development in food environment research. There is a need to investigate contextual influences within food environments as well as individual and household socio-economic characteristics that contribute to the differing use of and views towards local food environments. Greater emphasis on how individual and environmental factors interact in the food environment field will be key to developing stronger understanding of how environments can support and promote healthier food choices.

    The adverse environmental effects, especially energy use and resultant GHG emissions, of food production and consumption are becoming more widely appreciated and increasingly well documented. Our insights into the thorny problem of how to mitigate some of those effects, however, are far less evolved. Two of the most commonly advocated strategies are "organic" and "local", referring, respectively, to growing food without major inputs of fossil fuel based synthetic fertilizers and pesticides and to food consumption near its agricultural origin. Indeed, both agrochemical manufacture and transportation of produce to market make up a significant percentage of energy use in agriculture. While there can be unique environmental benefits to each strategy, "organic" and "local" each may potentially result in energy and emissions savings relative to conventionally grown produce. Here, we quantify the potential energy and greenhouse gas emissions savings associated with "organic" and "local". We take note of energy use and actual GHG costs of the major synthetic fertilizers and transportation by various modes routinely employed in agricultural distribution chains, and compare them for ~35 frequently consumed nutritional mainstays. We present new, current, lower-bound energy and greenhouse gas efficiency estimates for these items and compare energy consumption and GHG emissions incurred during producing those food items to consumption and emissions resulting from transporting them, considering travel distances ranging from local to continental and transportation modes ranging from (most efficient) rail to (least efficient) air. In performing those calculations, we demonstrate the environmental superiority of either local or organic over conventional foods, and illuminate the complexities involved in entertaining the timely yet currently unanswered, and previously unanswerable, question of "Which is Environmentally Superior, Organic or Local?". More broadly, we put forth a

    Substitutional carbon on an arsenic lattice site is the shallowest and one of the most dominant acceptors in semi-insulating Liquid Encapsulated Czochralski (LEC) GaAs. However, the role of this acceptor in determining the well known ''W'' shape spatial variation of neutral EL2 concentration along the diameter of a LEC wafer is not known. In this thesis, we attempt to clarify the issue of the carbon acceptor's effect on this ''W'' shaped variation by measuring spatial profiles of this acceptor along the radius of three different as-grown LEC GaAs wafers. With localized vibrational mode absorption spectroscopy, we find that the profile of the carbon acceptor is relatively constant along the radius of each wafer. Average values of concentration are 8 x 10E15 cm -3 , 1.1 x 10E15 cm -3 , and 2.2 x 10E15 cm -3 , respectively. In addition, these carbon acceptor LVM measurements indicate that a residual donor with concentration comparable to carbon exists in these wafers and it is a good candidate for the observed neutral EL2 concentration variation. 22 refs., 39 figs

    Full Text Available The purpose of this study is to examine attitudes and perceptions about organic cotton of Mississippi cotton growers and producers in comparison to fashion-conscious consumers, including advantages/disadvantages of growing and production processes, quality control, consumer preferences, and competitive price structures/profit margins. A sample size of 16 local Mississippi growers and/or producers and 44 undergraduate students at a mid-major Southeastern university were chosen to participate in the study. Instruments were developed based on current research and the definition of organic cotton production defined by the United States Department of Agriculture. Results indicate 75% of growers and producers do not perceive a quality difference between organic and conventionally grown cotton, while 72.7% of the consumers report organically grown cotton is capable of producing a higher quality product compared to conventionally grown cotton. Even with an increase in organic cotton prices (25- 40% higher premium, only 25% of growers and producers would be willing to convert, while a majority (52.3% of consumers would not be willing to spend more than 25% extra for an organically grown cotton product. Consumers indicate the negative effects of conventionally grown cotton, yet many report little knowledge about organic cotton production, while growers/producers immediately dismiss organically grown cotton as a retail marketing strategy.

    Full Text Available Due to the concerns about the long-term sustainability of globalized retail trade as well as the more and more determining health-conscious food-consuming attitude the systems of government respectively the groups of conscious consumers all over the world put emphasis on the popularization and development of local food chains and small-scale supply chains simultaneously they connect the retailers producing highquality, local foods with the direct markets. In my study, I would like to present an overview of the development and current state of community supported agricultural systems on the international and Hungarian level and on the basis of the results of my questionnaire survey. I will indicate whether there are any demand for local food in Hungary and about how much the population of the six investigated settlements are familiar with it. Within this type of alternative local food systems, farmers and their buyers form a community based on social capital (co-operation, mutual trust and mutual responsibility, a direct sales channel, in such a way that cooperation is also beneficial to the producer and the consumer. The producer is in an advantageous position as he can form a direct and long-term relationship with his consumers selling his high-quality products locally consequently he can work in a cost-effective and optimal way. However, the advantage of the consumer is that he can obtain healthy foods from reliable sources contributing to the maintenance of his health respectively to the development of local economy.

    2015-12-01

    Full Text Available Based on the threatening global challenge of increasing urban population with decreasing resources to feed them, the existing literature is reviewed in this paper to highlight; i the urban food supply chain, and ii food security as a benefit of Peri-Urban Agriculture. This is deployed to fit the context of the developing regions of the world where urbanization does not occur in an organized manner. It is known that food grown in peri-urban areas (defined as the fastest growing areas that surround cities but are neither urban nor rural in the conventional sense is easily available to urban inhabitants. Such peri-urban areas have the least adverse effects on the environment from a food transportation perspective and are more resilient in times of uncertain physical (disaster and socioeconomic (fuel and food price rise pressures. Today, much fertile peri-urban land is converted haphazardly without considering its environmental value and agricultural potential. Likewise, peri-urban agriculture is still in the process of being acknowledged by both locals and policy-makers despite being an accepted mode of achieving food security. Therefore, this paper seeks to orient the review literature and underline the gaps that prevail at the grass-roots level of local preferences and values and at the policy-maker level. Using extensive literature review as the methodology, this study draws recent ideas on the multi-functionality of peri-urban agriculture and the sustainable contribution it makes to both developed and developing countries around the world. The findings of the review highlight the significance of peri-urban areas in the Kathmandu Valley for a sustainable and a reliable food chain. It also shows the existing but unrecognized features of peri-urban agriculture both at local and policy-making levels. It discusses the point of interest and possible extension of the multifunctional peri-urban agriculture for local food access, inviting further

    This paper proposes an analytical framework for comparative studies of local food movements in Scandinavia and East Asia. The framework takes it point of departure in studying local food movements as engaging in political struggles over defining scales. The framework draws on political and economic...... geography theories that argue that scales such as local, regional, national, and global as socially constructed and relational to other scales that compete for dominance. The second part of this analytical framework will discuss scales as socio-political processes of boundary-making i.e. what aspects become...... included in defining a certain scale and what aspects are regarded as external to, or irrelevant, in defining the boundaries of scale. I argue that boundaries can be both material and symbolic/affective that connects the politics of scale to political struggles over society, the environment...

    Both obesity and food insecurity are important public health problems facing young children in the United States. A lack of affordable, healthy foods is one of the neighborhood factors presumed to underlie both food insecurity and obesity among children. We examine associations between local food prices and children's BMI, weight, and food security outcomes. We linked data from the Early Childhood Longitudinal Study-Birth Cohort, a nationally representative study of children from infancy to age 5, to local food price data from the Council for Community and Economic Research (C2ER) Cost-of-Living Index (n = 11,700 observations). Using ordinary least squares (OLS), linear probability, and within-child fixed effects (FE) models, we exploit the variability in food price data over time and among children who move residences focusing on a subsample of households under 300% of the Federal Poverty Level. Results from ordinary least squares and FE models indicate that higher-priced fruits and vegetables are associated with higher child BMI, and this relationship is driven by the prices of fresh (versus frozen or canned) fruits and vegetables. In the FE models, higher-priced soft drinks are associated with a lower likelihood of being overweight, and surprisingly, higher fast food prices are associated with a greater likelihood of being overweight. Policies that reduce the costs of fresh fruits and vegetables may be effective in promoting healthy weight outcomes among young children.

Le sujet est abordé d’une part en fonction de la relation entre ce type d’initiatives et le système agroalimentaire conventionnel et d’autre part en fonction de la possibilité du développement d’un système agroalimentaire plus durable. Basé sur trois études scandinaves, concernant des produits biologiques en Norvège et au Danemark, cet article souligne le fait que les différents acteurs intreviewés jouent à la fois sur le tableau du local et du biologique et sur le tableau du conventionnel. En dépit de différences structurelles distinctes, les deux systèmes, et les conventions qui leur sont rattachées, s’influencent mutuellement. Afin de mettre au point une agriculture plus durable, il semble donc important de mettre en valeur le fondement global de l’agriculture écologique, qui repose non seulement sur des valeurs biologiques et locales, mais encore sur des aspects économiques, sociaux et culturels qui doivent être pris en considération.The aim of this article is to discuss the importance of local initiatives for distribution of organic food. This subject is discussed both in relation to how such initiatives may affect the overall conventional food system and the possible implications for development of a more sustainable food system. The article is based on findings from three different cases of local, organic food in Norway and Denmark. We found that actors within the cases are both involved with local, organic food initiatives and at the same time part of the overall conventional food system. Even though there are distinctive structural differences between these distribution systems, they mutually affect each other. This means that conventions normally associated with local, organic food systems may ‘rub off’ to the conventional food system and vice versa. In order to develop

    2011-08-01

    The food related lifestyle (FRL) model, widely used on European data, is applied to US data using a modified survey instrument to examine organic and local food consumption. Since empirical studies indicate these shoppers are motivated by environmental and health concerns and limited by access, the conceptual framework employs an environmental behavior model, Attitude Behavior Context (ABC), which is consistent with means-end chain theory, the Health Belief (HB) model, and the FRL model. ABC theory incorporates contextual factors that may limit consumers' ability to act on their intentions. US food shopper data was collected in 2003 (n=956) utilizing an instrument with variables adapted from the FRL, ABC, and HB models. Cluster analysis segmented food shoppers into four FRL groups: rational, adventurous, careless, and a fourth segment that had some characteristics of both conservative and uninvolved consumers. The segments exhibited significant differences in organic and local food consumption. These were correlated with consumers' environmental concerns, knowledge and practices, health concerns and practices, as well as some demographic characteristics (race, gender, age, education), income, and variables that measured access to these foods. Implications for marketing and public policy strategies to promote organic and local foods include: emphasizing taste, nutrition, value, children, and enjoyment of cooking for rational consumers; and emphasizing health, fitness, and freshness, and providing ethnic foods for adventurous consumers. While both careless and conservative/uninvolved consumers valued convenience, the former tended to be in the highest income group, while the latter were in the lowest, were more likely to be either in the youngest or oldest age groups, and were very concerned about food safety and health.

  3. Do Local Food Networks Foster Socio-Ecological Transitions towards Food Sovereignty? Learning from Real Place Experiences

    2013-11-01

    Full Text Available Drawing on transition theory, we conceptualize local food networks as innovations that initially function and develop in local niches within a given food regime. As niche-innovations local food networks induce socio-ecological changes on the local level and they have the potential to foster wider transformations of the dominant food regime. Many local food networks adopt the concept of food sovereignty as a kind of “leitmotif”. At the core of this concept lies the question of how to create an agro-food system that, (i allows for democratic participation and civic engagement in food production, and (ii sets up new relationships that avoid social inequity and the exploitation of both humans and nature. In this paper we shed light on how the Austrian local food network “SpeiseLokal” addresses the challenge of operationalizing the concept of food sovereignty. The case study captures the strategies which local food networks embark on and depicts the difficulties they encounter. The paper aims to identify critical points of intersection that either strengthen or constrain local food networks from becoming established, operating, and up-scaling in the ways they wish; that is, in accordance with the principles and aims of food sovereignty, while avoiding a later assimilation into the dominant food regime.

  4. Consumer perception of sustainability attributes in organic and local food.

    Although sustainable food consumption is gaining growing importance on the international agenda, research on this subject is still quite fragmented and most studies analyse single aspects of sustainable food consumption with particular reference to environmental sustainability. In addition, the literature highlights the need to take account of the strong heterogeneity of consumers in studying sustainable behaviour. Identifying consumer segments with common profiles, needs and values is essential for developing effective communication strategies to promote sustainability in food consumption. Consumer segmentation based on the perception of the sustainability attributes of organic and local products was realized using descriptive data collected through a consumer online survey in southern Italy (Campania). K-means cluster analysis was performed to identify different consumer segments based on consumer perception of sustainable attributes in organic and local food. Results confirm the support of consumers for organic and local food as sustainable alternative in food choices even if occasional buying behaviour of these products still predominates. In addition, our results show that an egoistic approach prevails among consumers, who seem to attach more value to attributes related to quality and health than to environmental, social and economic sustainability. Segmentation proves the existence of three consumer segments that differ significantly in terms of perception of sustainability attributes: a large segment of individuals who seem more egocentric oriented, an environmental sustainability oriented segment and a small segment that includes sustainability oriented consumers. The existence of different levels of sensitivity to sustainability attributes in organic and local food among the identified segments could be duly considered by policy makers and other institutions in promoting sustainable consumption patterns. Consumers in the first cluster could be educated

    2011-03-01

    Much importance has been placed on the use of spatial cues by food-hoarding birds in the retrieval of their caches. In this study, we investigate whether food-hoarding birds can be trained to use local cues ("beacons") in their cache retrieval. We test magpies (Pica pica) in an active hoarding-retrieval paradigm, where local cues are always reliable, while spatial cues are not. Our results show that the birds use the local cues to retrieve their caches, even when occasionally contradicting spatial information is available. The design of our study does not allow us to test rigorously whether the birds prefer using local over spatial cues, nor to investigate the process through which they learn to use local cues. We furthermore provide evidence that magpies develop landmark preferences, which improve their retrieval accuracy. Our findings support the hypothesis that birds are flexible in their use of memory information, using a combination of the most reliable or salient information to retrieve their caches. © Springer-Verlag 2010

    The purpose of this study was to establish new food products that increase the nutritional value and health benefits of the probiotic yogurt currently used in the Western Heads East (WHE) Project in Mwanza, Tanzania. The probiotic yogurt has established health benefits, and product development through fortification must not adversely affect the acceptability of yogurt or the viability of the probiotics. Both sensory testing and microbial analysis testing were conducted. The products tested were yogurt fortified with locally-grown fruit purees with inulin and Moringa oleifera. The results of the sensory evaluation showed that all yogurts were not rated significantly different from the control, except for appearance.

    Malaysian locally processed raw food products are widely used as main ingredients in local cooking. Previous studies showed that these food products have a positive correlation with the incidence of cancer. The cytotoxicity effect was evaluated using MTT assay (3-(4,5-dimetil-2-thiazolil)-2,5-diphenyl-2H-tetrazolium bromide) against Chang liver cells at 2000 microg/ml following 72 h incubation. Findings showed all methanol extracts caused a tremendous drop in the percentage of cell viability at 2000 microg/ml (shrimp paste - 41.69+/-3.36%, salted fish - 37.2+/-1.06%, dried shrimp - 40.32+/-1.8%, pfood showed that shrimp paste did not comply with the protein requirement (Food Act 1983. Salt was found in every sample with the highest percentage being detected in shrimp paste which exceeded 20%. Following heavy metal analysis (arsenic, cadmium, lead and mercury), arsenic was found in every sample with dried shrimps showing the highest value as compared to the other samples (6.16 mg/kg). In conclusion, several food extracts showed cytotoxic effect but did not cause DNA damage against Chang liver cells. Salt was found as the main additive and arsenic was present in every sample, which could be the probable cause of the toxicity effects observed.

    Full Text Available Consumer attitudes toward consuming and buying locally produced food are well studied. By contrast, the topic of consumer preferences for local food, with a special emphasis on the role of norms, still lacks empirical evidence. To study the influence of norms and morals on the intention to buy local food products, a quantitative study (N = 327 focusing on external social and internalized moral norms was conducted using the constructs of the theory of planned behavior in combination with an extended norm taxonomy and the perceived consumer effectiveness measure. The norm constructs consisted of two different personal norms, integrated and introjected, and two social norms, descriptive and injunctive. In a factor analysis, two factors for social norms but only one for personal norms were obtained. Multiple regressions explained 50 percent of the variance in intentions and 29 percent of the variance in past behavior. Norm constructs were proven important in the model, as personal norms had the largest effect among all constructs on intentions, and descriptive norms strongly influenced past behavior. An additional mediation analysis showed that personal norms were internalized social injunctive norms and that intentions mediated the relationship between all constructs. The implications of the findings and recommendations for future research are given accordingly.

    One big challenge for the rest of the 21st century will be the massive urbanisation. It is expected that more than 7 out of 10 persons will live in a city by the year 2050. Crucial developments towards a sustainable future will therefore take place in cities. One important approach for a sustainable city development is to re-localize food production and to close urban nutrient cycles through better waste management. The re-location of food production avoids CO2 emissions from transportation of food to cities and can also generate income for inhabitants. Cities are by definition locations where fertility accumulates. As cities are often built along rivers, their soils are often fertile. Furthermore, labour force and the possibility of producing fertilizer from human fecal matter within the city promises sustainable nutrients cycles. Although urban and peri-urban agriculture can be found in many cities worldwide and already have a substantial contribution to food supply, it has not jet been comprehensibly structured by research. We combine several worldwide data sets to determine the supply of cities with regional food production, where regional is defined as a production that occurs very close to the consumption within the peri-urban area. Therefore, urban areas are not defined by administrative boundaries but by connected built-up urban areas, and peri-urban area by the surrounding area with the same size multiplied with a scaling parameter. Both together accumulate to an urban-bio-region (UBR). With regard to national food consumption, a linear program achieves the best possible yield on agricultural areas and allows the computation of the fraction of population, which can be nourished. Additionally, several climate scenarios and different dietary patterns were considered. To close the gap between single case studies and to provide a quantitative overview of the global potential of peri-urban food production we used high resolution land-use data Global Land Cover

    To identify and characterize initiatives that promote the purchase of locally-sourced foods to supply schools and the school centres carrying out the initiatives. Exploratory, descriptive study based on secondary data and key informant reports. A search of governmental and non-governmental initiatives was carried out at the autonomous community level. Government initiatives were located through school feeding programmes in the different autonomous communities, their nutritional guides and representatives of the councils for education and agriculture. Non-governmental initiatives were found through their own websites and the snowball technique. Initiatives were analysed by their geographic distribution, organizational area (government vs. non-government), number of school centres carrying out the initiatives, management style and organic food purchase. A descriptive analysis of the data was carried out. 12 initiatives carried out by 318 schools (2.16% of all the schools with food service in Spain) were identified. Among these, 6 are governmental initiatives with a scope of 274 schools (1.86%), and 6 are non-governmental initiatives with a scope of 44 schools (0.30%). Most of these schools have a public management system in place (n=284). All the initiatives provide for the purchase of organic food. Local food purchase initiatives in Spain have a limited reach. However, the existence of a state directive could support and strengthen the development of such initiatives, given that school commitment is greater when initiatives are driven by the public sector.

  18. Community context of food justice: reflections on a free local produce program in a New Orleans food desert

    2017-05-01

    Full Text Available Food justice discourse has emerged partly in response to the critique of alternative food networks during the last decade, but its justice conceptualization tends to be too narrowly focused on food-related injustices rather than broader social injustices that shape food access and food sovereignty, a gap we address. Our analysis of a semi-experimental free local food program we administered in a New Orleans food desert demonstrates that several community context factors shape the residents’ access to a local food market in this neighborhood: fragmented social ties, digital and generational divides, perpetual infrastructural failure, and the location of the market within the neighborhood. We argue that food justice discourse needs to incorporate social and cultural community contexts in its operationalization of food access and sovereignty, especially regarding how the latter concept is defined and executed in practice.

    This article examines the growing interest in local food by focusing on local food networks. The objective is to explore what factors drive or hinder the development of local food networks in rural Denmark. For this purpose, we have combined three bodies of theory: local food networks; entrepreneur...... networks; and the experience economy. This provides a valuable contribution to the current discourse on local food networks, as it introduces a novel framework to investigate the localisation of food dynamics. The article presents an explorative, case-based investigation of three Danish local food networks....... The findings demonstrate that the main drivers of the development of local food networks are the pursuance of transparency and knowledge of origin, the existence of entrepreneurship potential, the coordination of networks by means of joint strategies, and the overcoming of conflict patterns.

    The hetero-epitaxial strain relaxation in nano-scale systems plays a fundamental role in shaping their properties. Here, the elastic and plastic relaxation of self-assembled SiGe islands grown by surface-thermal-diffusion from a local Ge solid source on Si(100) are studied by atomic force and transmission electron microscopies, enabling the simultaneous investigation of the strain relaxation in different dynamical regimes. Islands grown by this technique remain dislocation-free and preserve a structural coherence with the substrate for a base width as large as 350 nm. The results indicate that a delay of the plastic relaxation is promoted by an enhanced Si-Ge intermixing, induced by the surface-thermal-diffusion, which takes place already in the SiGe overlayer before the formation of a critical nucleus. The local entropy of mixing dominates, leading the system toward a thermodynamic equilibrium, where non-dislocated, shallow islands with a low residual stress are energetically stable. These findings elucidate the role of the interface dynamics in modulating the lattice distortion at the nano-scale, and highlight the potential use of our growth strategy to create composition and strain-controlled nano-structures for new-generation devices.

    Phytoremediation is a technology for extracting or inactivating pollutants. Echinochloa polystachya [(H.B.K.) Hitchcock] (Poaceae) is a fast-growing perennial grass that is common in tropical areas and is often found in oil-polluted soils that contain high concentrations of heavy metals. However, its tolerance to heavy metals, and its ability to accumulate them, has yet to be investigated. Here we test the hypothesis that E. polystachya is able to accumulate high concentrations of cadmium (Cd). Plants were grown hydroponically with different levels of Cd{sup 2+} (0, 0.25, 1, 2, 10, 50, and 100 mg L{sup -1}), and were found to be tolerant to Cd{sup 2+} at all levels. No metal-toxicity symptoms were observed at any Cd{sup 2+} level. Root and leaves Cd concentrations were 299 {+-} 13.93 and 233 {+-} 8.77 mg kg{sup -1} (on a dry weight basis), respectively. Scanning electron microscopy showed the inclusion of Cd within the xylem; this result was confirmed by energy dispersive X-ray spectrometry. Leaf tissues also accumulated Cd, especially within the bulliform cells of the epidermis. We conclude that E. polystachya is a hyperaccumulator of Cd. While data for other metals are not yet available, E. polystachya shows promise in the phytoextraction of Cd from polluted tropical sites.

    The local consequences of fresh fall-out, especially in the case of atmospheric nuclear explosions, are reviewed from the point of view of the internal contamination of the consumer of foodstuffs of animal origin. The edibility of foodstuffs derived from animals having grazed in the presence of fall-out is evaluated both from the wholesome and radio-toxicological points of view. The contamination level of these foodstuffs is calculated as a function of the ground fall-out, and of agronomical and ecological parameters for each radio-nuclide of the animal food chain. The internal exposure of the human consumer is calculated from this level as a function of the diet and of various parameters especially temporal. The equivalent dose to each critical organ, including the digestive tract is deduced from the burdens of each organ. From this a nutritional hygiene in the areas affected by fall-out is obtained, in relationship to the action levels fixed by the responsible authorities in exceptional circumstances. Criteria for these action levels are given as function of the food rations. (authors) [fr

    In a previous study by our group, CH4 oxidation and N2 fixation were simultaneously activated in the roots of wild-type rice plants in a paddy field with no N input; both processes are likely controlled by a rice gene for microbial symbiosis. The present study examined which microorganisms in rice roots were responsible for CH4 oxidation and N2 fixation under the field conditions. Metaproteomic analysis of root-associated bacteria from field-grown rice (Oryza sativa Nipponbare) revealed that nitrogenase complex-containing nitrogenase reductase (NifH) and the alpha subunit (NifD) and beta subunit (NifK) of dinitrogenase were mainly derived from type II methanotrophic bacteria of the family Methylocystaceae, including Methylosinus spp. Minor nitrogenase proteins such as Methylocella, Bradyrhizobium, Rhodopseudomonas, and Anaeromyxobacter were also detected. Methane monooxygenase proteins (PmoCBA and MmoXYZCBG) were detected in the same bacterial group of the Methylocystaceae. Because these results indicated that Methylocystaceae members mediate both CH4 oxidation and N2 fixation, we examined their localization in rice tissues by using catalyzed reporter deposition-fluorescence in situ hybridization (CARD-FISH). The methanotrophs were localized around the epidermal cells and vascular cylinder in the root tissues of the field-grown rice plants. Our metaproteomics and CARD-FISH results suggest that CH4 oxidation and N2 fixation are performed mainly by type II methanotrophs of the Methylocystaceae, including Methylosinus spp., inhabiting the vascular bundles and epidermal cells of rice roots.

    Microalgae, Scenedesmus bijuga, was cultivated in anaerobically digested food wastewater effluent (FWE) to treat the wastewater and produce biodiesel simultaneously. Three different mixing ratios with municipal wastewater were compared for finding out proper dilution ratio in biodiesel production. Of these, 1/20 diluted FWE showed the highest biomass production (1.49 g/L). Lipid content was highest in 1/10 diluted FWE (35.06%), and the lipid productivity showed maximum value in 1/20 diluted FWE (15.59 mg/L/d). Nutrient removal was also measured in the cultivation. FAME compositions were mainly composed of C16-C18 (Over 98.94%) in S. bijuga. In addition, quality of FAMEs was evaluated by Cetane Number (CN) and Bis-allylic Position Equivalent (BAPE).

    Full text: Two types of legume-based (lentils/chickpea) and two types of fish-based (carp/catfish) formulas have been made in the form of dry powder, from locally available foods. By analysis of the nutrient composition of formulas, the lentil formula provides 410 calories (11.7g of protein), chickpea formula (418 calories, 13.5g of protein), catfish formula (428 calories, 16.1g of protein) and carp formula (432 calories, 15.8g of protein) in 100g dry weight of each formula. All the formulas were adequate in protein and energy density to meet the WHO recommended value for nutrition needs of 6-12 months old infants. The results of bacteriological analyses showed all the samples were within the recommended microbiological limits for dried products requiring preparation with boiling water. No physical changes were observed when the formulas were stored in sealed plastic bags at room temperature for 6 months. Developed products were evaluated for their acceptability by a panel of 20 persons using 4-point Hedonic Rating Scale. Results from sensory analysis showed that catfish formula obtained highest score for its color, lentil formula for its aroma and taste, and the lowest to carp formula. In the acceptability trials done on 25 children, 82%-90% of the mothers reported that the mixes were acceptable to their children. No adverse side effects were noticed. More than half of the mothers reported their children refused to eat other family foods and showed an obvious preference for the mixes, especially the one made by lentil. (author)

    Vertically grown single-walled carbon nanotube (V-SWCNT) forests, synthesized by water-assisted plasma-enhanced chemical vapor deposition, were studied using polarized micro-Raman spectroscopy. Among three different sections (root, center and end) along the vertical growth direction, the degree of V-SWCNT alignment was highest in the center section. Raman frequency red-shifts up to 7 and 13 cm −1 , for RBM and G-band, respectively, were observed in the center section, with respect to the Raman frequencies measured in the root and the end sections. Raman frequency downshift and concurrent linewidth broadening of the G-band, revealing a localized strain, were also observed in the center section. The existence of a localized strain in the center section of the V-SWCNT was further confirmed by observing a strong polarization anisotropy of up to 8 cm −1 in the G-band Raman frequency for different polarized Raman scattering configurations at the same probed spot.

    Government actors have an important role to play in creating healthy public policies and supportive environments to facilitate access to safe, affordable, nutritious food. The purpose of this research was to examine Waterloo Region (Ontario, Canada) as a case study for "what works" with respect to facilitating access to healthy, local food through regional food system policy making. Policy and planning approaches were explored through multi-sectoral perspectives of: (a) the development and adoption of food policies as part of the comprehensive planning process; (b) barriers to food system planning; and (c) the role and motivation of the Region's public health and planning departments in food system policy making. Forty-seven in-depth interviews with decision makers, experts in public health and planning, and local food system stakeholders provided rich insight into strategic government actions, as well as the local and historical context within which food system policies were developed. Grounded theory methods were used to identify key overarching themes including: "strategic positioning", "partnerships" and "knowledge transfer" and related sub-themes ("aligned agendas", "issue framing", "visioning" and "legitimacy"). A conceptual framework to illustrate the process and features of food system policy making is presented and can be used as a starting point to  engage multi-sectoral stakeholders in plans and actions to facilitate access to healthy food.

  13. Factors Constraining Local Food Crop Production in Indonesia: Experiences from Kulon Progo Regency, Yogyakarta Special Province

    Full Text Available Local food crops are believed to be important alternatives in facing the problems of continuously growing price of food stuff worldwide. There has been a strong bias in national agricultural development policy towards the production of rice as staple food in Indonesia. Local food crops have been neglected in the agricultural development policy in the last 50 years, leading to the dependency on imported commodities and creating a vulnerability in the national food security. This paper aims at assessing the factors constraining local food production in Indonesia based on empirical experiences drawn from a research in Kulon Progo Regency, Yogyakarta Province. The government of Kulon Progo Regency has declared its commitment in the development of local food commodities as a part of its agricultural development policy, as it is mentioned in the long-term and medium-term development planning documents. There is also a head regency decree mandating the use of local food commodities in any official events organized by the government organisations. The research shows that there are at least six policy-related problems and nine technical factors constraining local food crops production in the regency. Some of the policy-related and structural factors hampering the production of local food crops consist of (1 long-term policy biases towards rice, (2 strong biases on rice diet in the community, (3 difficulties in linking policy to practices, (4 lack of information on availability of local food crops across the regency and (5 external threat from the readily available instant food on local market and (6 past contra-productive policy to the production of local food crops. The technical factors constraining local food production comprises (1 inferiority of the food stuff versus the instantly prepared food, (2 difficulty in preparation and risk of contagion of some crops, lack of technology for processing, (3 continuity of supply (some crops are seasonally

  14. Are Local Food Chains More Sustainable than Global Food Chains? Considerations for Assessment

    Directory of Open Access Journals (Sweden)

    Gianluca Brunori

    2016-05-01

    Full Text Available This paper summarizes the main findings of the GLAMUR project which starts with an apparently simple question: is “local” more sustainable than “global”? Sustainability assessment is framed within a post-normal science perspective, advocating the integration of public deliberation and scientific research. The assessment spans 39 local, intermediate and global supply chain case studies across different commodities and countries. Assessment criteria cover environmental, economic, social, health and ethical sustainability dimensions. A closer view of the food system demonstrates a highly dynamic local–global continuum where actors, while adapting to a changing environment, establish multiple relations and animate several chain configurations. The evidence suggests caution when comparing “local” and “global” chains, especially when using the outcomes of the comparison in decision-making. Supply chains are analytical constructs that necessarily—and arbitrarily—are confined by system boundaries, isolating a set of elements from an interconnected whole. Even consolidated approaches, such as Life Cycle Assessment (LCA, assess only a part of sustainability attributes, and the interpretation may be controversial. Many sustainability attributes are not yet measurable and “hard” methodologies need to be complemented by “soft” methodologies which are at least able to identify critical issues and trade-offs. Aware of these limitations, our research shows that comparing local and global chains, with the necessary caution, can help overcome a priori positions that so far have characterized the debate between “localists” and “globalists”. At firm level, comparison between “local” and “global” chains could be useful to identify best practices, benchmarks, critical points, and errors to avoid. As sustainability is not a status to achieve, but a never-ending process, comparison and deliberation can be the basis of a

    To prepare various crude extracts using different polarities of solvent and to quantitatively evaluate their total phenol, flavonoids contents and phytochemical screening of Thymus vulgaris collected from Al Jabal Al Akhdar, Nizwa, Sultanate of Oman. The leave sample was extracted with methanol and evaporated. Then it was defatted with water and extracted with different polarities organic solvents with increasing polarities. The prepare hexane, chloroform, ethyl acetate, butanol and methanol crude extracts were used for their evaluation of total phenol, flavonoids contents and phytochemical screening study. The established conventional methods were used for quantitative determination of total phenol, flavonoids contents and phytochemical screening. Phytochemical screening for various crude extracts were tested and shown positive result for flavonoids, saponins and steroids compounds. The result for total phenol content was the highest in butanol and the lowest in methanol crude extract whereas the total flavonoids contents was the highest in methanol and the lowest hexane crude extract. The crude extracts from locally grown Thymus vulgaris showed high concentration of flavonoids and it could be used as antibiotics for different curable and uncurable diseases.

    The present study investigated the effects of three temperature regimes, low (20 degree C), moderate (25 degree C) and high (30 degree C), on growth and physiological parameters of two local Saudi wheat (Triticum durum) cultivars, Hab-Ahmar and Algaimi. Plants were grown under controlled environment in growth chambers. After four weeks plants were harvested and the following growth parameters were measured; plant height, number of tillers, leaf area, root length, fresh and dry weight. Physiological traits include chlorophyll content, photosynthesis rates, stomatal conductance, dark respiration and chlorophyll fluorescence parameters; Fo, Fm and Fv/Fm. In cultivar Hab-Ahmar, moderate and high temperatures caused significant decrease in most growth and physiological parameters such as plant height, number of tillers, leaf area, fresh and dry weight, chlorophyll content, photosynthesis rates, stomatal conductance, dark respiration and the maximum quantum yield of photosystem II (Fv/Fm). In contrast, cv. Algaimi was shown to be more thermotolerant to moderate and high temperatures, with the exception of some growth parameters that were decreased. Unlike cultivar Hab-Ahmar, cultivar Algaimi had an increased rate of dark respiration when temperature was high (30 degree C). Stomatal behavior is shown to be positively correlated with the rates of photosynthesis in both cultivars; however, in cultivar Hab-Ahmar such correlation decreased as temperature increased.

    There is growing interest in use of local food within health care institutions such as hospitals and long-term care homes. This study explored stakeholder perspectives on (i) influences on local food use and (ii) strategies that support success and sustainability of use in health care institutions. Fifteen participants who were institutional leaders with experience in implementing or supporting local food use in health care institutions in Ontario were recruited through purposeful and snowball sampling. A semi-structured interview was conducted by telephone and audio-recorded. Qualitative content analysis identified that influences on local food use were: product availability, staff and management engagement, and legislation and resources (e.g., funding, labour). Several strategies were offered for building and sustaining success including: setting goals, requesting local food availability from suppliers, and more clearly identifying local foods in product lists. The influences and potential strategies highlighted in this paper provide a greater understanding for dietitians and food service managers on how local foods can be incorporated into health care institutions.

    The local consequences of fresh fall-out, especially in the case of atmospheric nuclear explosions, are reviewed from the point of view of the internal contamination of the consumer of foodstuffs of animal origin. The edibility of foodstuffs derived from animals having grazed in the presence of fall-out is evaluated both from the wholesome and radio-toxicological points of view. The contamination level of these foodstuffs is calculated as a function of the ground fall-out, and of agronomical and ecological parameters for each radio-nuclide of the animal food chain. The internal exposure of the human consumer is calculated from this level as a function of the diet and of various parameters especially temporal. The equivalent dose to each critical organ, including the digestive tract is deduced from the burdens of each organ. From this a nutritional hygiene in the areas affected by fall-out is obtained, in relationship to the action levels fixed by the responsible authorities in exceptional circumstances.

  10. Relation between local food environments and obesity among adults

    Raine Kim D

    2009-06-01

    Full Text Available Abstract Background Outside of the United States, evidence for associations between exposure to fast-food establishments and risk for obesity among adults is limited and equivocal. The purposes of this study were to investigate whether the relative availability of different types of food retailers around people's homes was associated with obesity among adults in Edmonton, Canada, and if this association varied as a function of distance between food locations and people's homes. Methods Data from a population health survey of 2900 adults (18 years or older conducted in 2002 was linked with geographic measures of access to food retailers. Based upon a ratio of the number of fast-food restaurants and convenience stores to supermarkets and specialty food stores, a Retail Food Environment Index (RFEI was calculated for 800 m and 1600 m buffers around people's homes. In a series of logistic regressions, associations between the RFEI and the level of obesity among adults were examined. Results The median RFEI for adults in Edmonton was 4.00 within an 800 m buffer around their residence and 6.46 within a 1600 m buffer around their residence. Approximately 14% of the respondents were classified as being obese. The odds of a resident being obese were significantly lower (OR = 0.75, 95%CI 0.59 – 0.95 if they lived in an area with the lowest RFEI (below 3.0 in comparison to the highest RFEI (5.0 and above. These associations existed regardless of the covariates included in the model. No significant associations were observed between RFEI within a 1600 m buffer of the home and obesity. Conclusion The lower the ratio of fast-food restaurants and convenience stores to grocery stores and produce vendors near people's homes, the lower the odds of being obese. Thus the proximity of the obesogenic environment to individuals appears to be an important factor in their risk for obesity.

    To describe availability and frequency of use of local snack-food outlets and determine whether reported use of these outlets was associated with dietary intakes. Data were cross-sectional. Availability and frequency of use of three types of local snack-food outlets were reported. Daily dietary intakes were based on the average of up to four 24 h dietary recalls. Multivariable linear regression models estimated average daily intakes of energy, sugar-sweetened beverages (SSB) and snack foods/sweets associated with use of outlets. Multi-site, observational cohort study in the USA, 2004-2006. Girls aged 6-8 years (n 1010). Weekly frequency of use of local snack-food outlets increased with number of available types of outlets. Girls with access to only one type of outlet reported consuming food/beverage items less frequently than girls with access to two or three types of outlets (P snack foods/sweets intakes increased with greater use of outlets. Girls who reported using outlets>1 to 3 times/week consumed 0·27 (95 % CI 0·13, 0·40) servings of SSB more daily than girls who reported no use. Girls who reported using outlets>3 times/week consumed 449·61 (95 % CI 134·93, 764·29) kJ, 0·43 (95 % CI 0·29, 0·58) servings of SSB and 0·38 (95 % CI 0·12, 0·65) servings of snack foods/sweets more daily than those who reported no use. Girls' frequency of use of local snack-food outlets increases with the number of available types of outlets and is associated with greater daily intakes of energy and servings of SSB and snack foods/sweets.

  12. Sustainability of Global and Local Food Value Chains: An Empirical Comparison of Peruvian and Belgian Asparagus

    2016-04-01

    Full Text Available The sustainability of food value chains is an increasing concern for consumers, food companies and policy-makers. Global food chains are often perceived to be less sustainable than local food chains. Yet, thorough food chain analyses and comparisons of different food chains across sustainability dimensions are rare. In this article we analyze the local Belgian and global Peruvian asparagus value chains and explore their sustainability performance. A range of indicators linked to environmental, economic and social impacts is calculated to analyze the contribution of the supply chains to economic development, resource use, labor relations, distribution of added value and governance issues. Our findings suggest that none of the two supply chains performs invariably better and that there are trade-offs among and between sustainability dimensions. Whereas the global chain uses water and other inputs more intensively and generates more employment per unit of land and higher yields, the local chain generates more revenue per unit of land.

  13. LOCAL FOOD SYSTEMS DEVELOPMENT IN THE REPUBLIC OF MOLDOVA: CHALLENGES AND OPPORTUNITIES

    Directory of Open Access Journals (Sweden)

    2013-01-01

    Full Text Available The main challenge of the food sector in the Republic of Moldova is to identify specific needs and opportunities for agriculture and rural development throughout food supply chains, and focusing investment in areas where the most impact will be made. The identification and allocation of resources requires analysis of main dimensions of food supply chains, in order to establish links and determine local factors. In small transition economies the diagnosis of the food supply chains, is typically based on limited data and incomplete information. In order to investigate the actual state of food supply chains were used specific methods and techniques: statistical and economic analysis of macro-economic indicators, semi-structured interviews of key stakeholders, analysis of the impact of public policies on the agro-food sector. In the article is analyzed the process of food systems formation and integration at the local and global level. Although it is a small part of the overall agricultural sector, various local food systems are under development in the Republic of Moldova. These systems bring consumers in close contact with farmers and mobilize them to support local farms and sustainable farming practices. While local food systems continue to face many barriers, many of them show considerable potential for growth.

    Food insecurity and its most extreme form, hunger, have increased exponentially in the United States since 2006. This essay seeks to contribute to our understanding of hunger by attending to the context of the financial crisis as an organizing frame for understanding local meanings of hunger. Within a broader framework of the culture-centered approach (CCA) that works to identify and develop locally rooted solutions to food insecurity, we describe through locally grounded stories of food insecurity the financial climate where large percentages of U.S. households have been cast into poverty because of the crash of an unregulated economy. These local understandings of hunger in the context of the economy offer entry points for organizing a food-insecure coalition that seeks to address the stigma around food insecurity.

    2012-03-01

    Full Text Available  This paper investigates the rationale for local and sustainable food systems and retailer co-operatives as their entry points within local conditions. Emphasis is on localised food networks and connection between socially as well as environmentally sustainable production, distribution and consumption. Investigated is the premise that co-operative organisational structures, for reasons of their long-term socially responsible origins are at the forefront of development of local and sustainable food systems and are thereby in a position to offer a specific contribution to market development. Two key research questions are proposed: Firstly, is there a pre-determination of co-operatives to issues of sustainable and local food sourcing given the historical and practical context of their ethical/socially responsible and stakeholder-based business model? Secondly, do co-ops express support for re-localising food systems and what contribution do they make concerning sustainable food and their relationships with local food suppliers? The method of investigation is through a two country retailer co-operative sector analysis and comparison (Finland and Italy. The enquiry is qualitative and exploratory in nature in the form of an embedded, multiple case design. The paper makes practical and theoretical contribution to knowledge concerning interpretation of ‘localness’ in food, the role of co-operatives and the co-operative ethos in sustainable food systems and the development of the local food economy. Results of the study show a positive relationship between co-operative ethos and (social sustainability in local food, but the de-centralised nature of retailer co-operation also provides a barrier to replication of good practice.

    Full Text Available This article focuses on local food and the associated meanings in the ethnic area of central China and is based on field research in Enshi prefecture, a Tujia-Miao autonomous prefecture that lies in the southwest Hubei province. As in many other areas in contemporary China, the local food in south west Hubei, central China, known as hezha food, has been integrated into the urban restaurant system and has acquired a variety of meanings. In Enshi prefecture, special varieties of local food, such as hezha, baogufan (a dish made of maize flour and rice, tularou (smoked pork and zhaguangjiao (a preserved food made of maize flour and red chili pepper had long been treated as markers of local regional food or of “coarse” country cuisine. A combination of maize’s reliable high yield in mountain fields and local people’s culinary wisdom, has meant that hezha food has played a key role in the modern history of this mountain area. Up to the early 1990s, the common dish made of maize has served as the marker of mountain life (described as miserable life sometimes. In the early 1990s, when the Chinese government launched a nationwide rural development project, Enshi’s officials went to villagers’ kitchens to check if a maize dish was being replaced with that of rice. However, such food of the poor people did not disappear at all with rural development. Many farmers said that they had easier access to meat (pork and rice (which symbolize a higher standard of living and is often associated with Han, the majority than ever before, but since the mid-1990s, Enshi prefecture has witnessed a conspicuous phenomenon of local people returning to “coarse” local food despite an abundance of meat and rice. What is more, such local food has found its way into the urban restaurant system: as food in the Hezha restaurants, Ethnic restaurants, as well as Farmhouse Joy restaurants. The standardization of local food in these restaurants has involved both

  20. "Closing the Loop": Overcoming barriers to locally sourcing food in Fort Collins, Colorado

    DeMets, C. M.

    2012-12-01

    Environmental sustainability has become a focal point for many communities in recent years, and restaurants are seeking creative ways to become more sustainable. As many chefs realize, sourcing food locally is an important step towards sustainability and towards building a healthy, resilient community. Review of literature on sustainability in restaurants and the local food movement revealed that chefs face many barriers to sourcing their food locally, but that there are also many solutions for overcoming these barriers that chefs are in the early stages of exploring. Therefore, the purpose of this research is to identify barriers to local sourcing and investigate how some restaurants are working to overcome those barriers in the city of Fort Collins, Colorado. To do this, interviews were conducted with four subjects who guide purchasing decisions for restaurants in Fort Collins. Two of these restaurants have created successful solutions and are able to source most of their food locally. The other two are interested in and working towards sourcing locally but have not yet been able to overcome barriers, and therefore only source a few local items. Findings show that there are four barriers and nine solutions commonly identified by each of the subjects. The research found differences between those who source most of their food locally and those who have not made as much progress in local sourcing. Based on these results, two solution flowcharts were created, one for primary barriers and one for secondary barriers, for restaurants to assess where they are in the local food chain and how they can more successfully source food locally. As there are few explicit connections between this research question and climate change, it is important to consider the implicit connections that motivate and justify this research. The question of whether or not greenhouse gas emissions are lower for locally sourced food is a topic of much debate, and while there are major developments

  1. Competitiveness of Small Farms and Innovative Food Supply Chains: The Role of Food Hubs in Creating Sustainable Regional and Local Food Systems

    Directory of Open Access Journals (Sweden)

    Giaime Berti

    2016-07-01

    Full Text Available Over the last decades, the economic, social and environmental sustainability of the conventional agri-food system has and continues to be contested within both academic and public institutions. For small farms, the unsustainability of the food system is even more serious; farms’ declining share of profit and the cost-price squeeze of commodity production has increased barriers to market access with the inevitable effect of agricultural abandonment. One way forward to respond to the existing conventional agri-food systems and to create a competitive or survival strategy for small family farms is the re-construction of regional and local agri-food systems, aligning with Kramer and Porter’s concept of shared value strategy. Through a critical literature review, this paper presents “regional and local food hubs” as innovative organizational arrangements capable of bridging structural holes in the agri-food markets between small producers and the consumers—individuals and families as well as big buyers. Food hubs respond to a supply chain (or supply network organizational strategy aiming at re-territorialising the agri-food systems through the construction of what in the economic literature are defined as values-based food supply chains.

    Full Text Available The specific objectives are: i to determine the level of awareness of pesticide residue in locally available food among food sellers in Ile Ife area of Osun state, Nigeria; ii to identify the demographic and socio-economic characteristics of food sellers who use pesticides, natural means in preserving their foodstuff from getting spoilt; iii to determine the level of understanding of food sellers who use pesticides about the likely health implications that could result. The design of the study is cross sectional. Structured open-ended questionnaires were administered to 98 randomly selected food sellers in Ile Ife area Osun state, Nigeria. This includes males and female. The inference from the study shows that majority of the food sellers were between ages 21 and 30 years, suggesting that more of the young people are involved in the selling of foodstuff in the area of study. Most of the food sellers used phostozin, an organophosphate compound as preservatives for cereals. The majority of those that were aware of the health hazards associated with the usage of pesticides as preservative were literate school leavers. Among respondents to the questionnaire, it was expected that many of those food sellers likely to demonstrate caution in the usage of pesticide would be the literate school leavers. This is because they are more aware of the possible associated health hazards than their fellow food sellers who are not literate. The level of awareness of health implications associated with use of pesticides on consumable food items is higher among school certificate holders who are food sellers. Phostozin, an organophosphate, is a common preservative pesticide used on cereals foodstuff (e.g., bean, rice, maize in the area of study, especially among the age group between 21 and 30 years.

    We investigated the relationship of the local availability of fast-food restaurant locations with diet and obesity. We geocoded addresses of survey respondents and fast-food restaurant locations to assess the association between the local concentration of fast-food outlets, BMI, and fruit and vegetable consumption. The survey was conducted in Genesee County, Michigan. There were 1345 individuals included in this analysis, and the response rate was 25%. The Speak to Your Health! Community Survey included fruit and vegetable consumption items from the Behavioral Risk Factor Surveillance System, height, weight, and demographics. We used ArcGIS to map fast-food outlets and survey respondents. Stepwise linear regressions identified unique predictors of body mass index (BMI) and fruit and vegetable consumption. Survey respondents had 8 ± 7 fast-food outlets within 2 miles of their home. Individuals living in close proximity to fast-food restaurants had higher BMIs t(1342) = 3.21, p food availability, which may constrain the success of nutrition promotion efforts. Efforts to decrease the local availability of unhealthy foods as well as programs to help consumers identify strategies for obtaining healthy meals at fast-food outlets may improve health outcomes.

    Interventions that enhance linkages between healthy diets and local agriculture can promote sustainable food systems. Home-grown school feeding programs present a promising entry point for such interventions, through the delivery of nutritious menus and meals. To describe the adaptation of the School Meals Planner Package to the programmatic and environmental reality in Ghana during the 2014 to 2015 school year. Guided by a conceptual framework highlighting key considerations and trade-offs in menu design, an open-source software was developed that could be easily understood by program implementers. Readily available containers from markets were calibrated into "handy measures" to support the provision of adequate quantities of food indicated by menus. Schools and communities were sensitized to the benefits of locally sourced, nutrient-rich diets. A behavior change communication campaign including posters and songs promoting healthy diets was designed and disseminated in schools and communities. The School Meals Planner Package was introduced in 42 districts in Ghana, reaching more than 320 000 children. Monitoring reports and feedback on its use were positive, demonstrating how the tool can be used by planners and implementers alike to deliver nutritious, locally-sourced meals to schoolchildren. The value of the tool has been recognized at the highest levels by Ghana's government who have adopted it as official policy. The School Meals Planner Package supported the design of nutritious, locally sourced menus for the school feeding program in Ghana. The tool can be similarly adapted for other countries to meet context-specific needs. © The Author(s) 2016.

    2012-09-01

    Despite growing attention to the problem of obesogenic environments, there has not been a comprehensive review evaluating the food environment-diet relationship. This study aims to evaluate this relationship in the current literature, focusing specifically on the method of exposure assessment (GIS, survey, or store audit). This study also explores 5 dimensions of "food access" (availability, accessibility, affordability, accommodation, acceptability) using a conceptual definition proposed by Penchansky and Thomas (1981). Articles were retrieved through a systematic keyword search in Web of Science and supplemented by the reference lists of included studies. Thirty-eight studies were reviewed and categorized by the exposure assessment method and the conceptual dimensions of access it captured. GIS-based measures were the most common measures, but were less consistently associated with diet than other measures. Few studies examined dimensions of affordability, accommodation, and acceptability. Because GIS-based measures on their own may not capture important non-geographic dimensions of access, a set of recommendations for future researchers is outlined. Copyright © 2012 Elsevier Ltd.

    Full Text Available This article highlights the importance of short food supply chains for the development of rural areas in Romania, considering the increasing demand of the population for healthy food. A proper functionality of these local food supply chains brings benefits to producers, consumers and the local community, but some issues must be solved. This article presents the results of a qualitative marketing research study conducted for identifying the difficulties in this sector. The study aimed to identify the small producers’ opinions on the barriers to the development of these supply chains and how they could be helped to sell their products at a fair price.

    Salmonella Give is a rare serotype across Europe. In October 2016, a national outbreak of S. Give occurred in Malta. We describe the epidemiological, environmental, microbiological and veterinary investigations. Whole-genome sequencing (WGS) was performed on human, food, environmental and veterinary isolates. Thirty-six human cases were reported between October and November 2016, 10 (28%) of whom required hospitalisation. Twenty-six (72%) cases were linked to four restaurants. S. Give was isolated from ready-to-eat antipasti served by three restaurants which were all supplied by the same local food manufacturer. Food-trace-back investigations identified S. Give in packaged bean dips, ham, pork and an asymptomatic food handler at the manufacturer; inspections found inadequate separation between raw and ready-to-eat food during processing. WGS indicated two genetically distinguishable strains of S. Give with two distinct clusters identified; one cluster linked to the local food manufacturer and a second linked to veterinary samples. Epidemiological, environmental and WGS evidence pointed towards cross-contamination of raw and ready-to-eat foods at the local manufacturer as the likely source of one cluster. Severity of illness indicates a high virulence of this specific serotype. To prevent future cases and outbreaks, adherence to food safety practices at manufacturing level need to be reinforced.

  15. Relative Preference and Localized Food Affect Predator Space Use and Consumption of Incidental Prey.

    Directory of Open Access Journals (Sweden)

    Tyler E Schartel

    Full Text Available Abundant, localized foods can concentrate predators and their foraging efforts, thus altering both the spatial distribution of predation risk and predator preferences for prey that are encountered incidentally. However, few investigations have quantified the spatial scale over which localized foods affect predator foraging behavior and consumption of incidental prey. In spring 2010, we experimentally tested how point-source foods altered how generalist predators (white-footed mice, Peromyscus leucopus utilized space and depredated two incidental prey items: almonds (Prunus dulcis; highly profitable and maple seeds (Acer saccharum; less profitable. We estimated mouse population densities with trapping webs, quantified mouse consumption rates of these incidental prey items, and measured local mouse activity with track plates. We predicted that 1 mouse activity would be elevated near full feeders, but depressed at intermediate distances from the feeder, 2 consumption of both incidental prey would be high near feeders providing less-preferred food and, 3 consumption of incidental prey would be contingent on predator preference for prey relative to feeders providing more-preferred food. Mouse densities increased significantly from pre- to post-experiment. Mean mouse activity was unexpectedly greatest in control treatments, particularly <15 m from the control (empty feeder. Feeders with highly preferred food (sunflower seeds created localized refuges for incidental prey at intermediate distances (15 to 25m from the feeder. Feeders with less-preferred food (corn generated localized high risk for highly preferred almonds <10 m of the feeder. Our findings highlight the contingent but predictable effects of locally abundant food on risk experienced by incidental prey, which can be positive or negative depending on both spatial proximity and relative preference.

    Large price increases over a short time period can be indicative of a deteriorating food security situation. Food price indices developed by the United Nations Food and Agriculture Organization (FAO) are used to monitor food price trends at a global level, but largely reflect supply and demand conditions in export markets. However, reporting by the United States Agency for International Development (USAID)'s Famine Early Warning Systems Network (FEWS NET) indicates that staple cereal prices in many markets of the developing world, especially in surplus-producing areas, often have a delayed and variable response to international export market price trends. Here we present new price indices compiled for improved food security monitoring and assessment, and specifically for monitoring conditions of food access across diverse food insecure regions. We found that cereal price indices constructed using market prices within a food insecure region showed significant differences from the international cereals price, and had a variable price dispersion across markets within each marketshed. Using satellite-derived remote sensing information that estimates local production and the FAO Cereals Index as predictors, we were able to forecast movements of the local or national price indices in the remote, arid and semi-arid countries of the 38 countries examined. This work supports the need for improved decision-making about targeted aid and humanitarian relief, by providing earlier early warning of food security crises.

    We examined associations between fast-food intake and perceived and objective fast-food outlet exposure. Information from the Health Behaviours in School-aged Children Study was linked to fast-food outlets in seventy-five school neighbourhoods. We used multivariate multilevel logistic regression analyses to examine associations between at least weekly fast-food intake and perceived and objective fast-food outlet measures. Data represent 4642 adolescents (aged 11-15 years) in Denmark. Boys reporting two or more fast-food outlets had 34% higher odds consuming fast food at least weekly. We detected higher odds of at least weekly fast-food intake among 15-year-old 9th graders (ORall=1.74; 95% CI 1.40, 2.18; ORboys=2.20; 95% CI 1.66, 2.91; ORgirls=1.41; 95% CI 1.03, 1.92), Danish speakers (ORall=2.32; 95% CI 1.68, 3.19; ORboys=2.58; 95% CI 1.69, 3.93; ORgirls=2.37; 95% CI 1.46, 3.84) and those travelling 15 min or less to school (ORall=1.21; 95% CI 1.00, 1.46; ORgirls=1.44; 95% CI 1.08, 1.93) compared with 11-year-old 5th graders, non-Danish speakers and those with longer travel times. Boys from middle- (OR=1.28; 95% CI 1.00, 1.65) and girls from low-income families (OR=1.46; 95% CI 1.05, 2.04) had higher odds of at least weekly fast-food intake compared with those from high-income backgrounds. Girls attending schools with canteens (OR=1.47; 95% CI 1.00, 2.15) had higher odds of at least weekly fast-food intake than girls at schools without canteens. The present study demonstrates that perceived food outlets may impact fast-food intake in boys while proximity impacts intake in girls. Public health planning could target food environments that emphasize a better understanding of how adolescents use local resources.

    2011-09-01

    The obesity epidemic cannot be reversed without substantial improvements in the food marketing environment that surrounds children. Food marketing targeted to children almost exclusively promotes calorie-dense, nutrient-poor foods and takes advantage of children's vulnerability to persuasive messages. Increasing scientific evidence reveals potentially profound effects of food marketing on children's lifelong eating behaviors and health. Much of this marketing occurs in nationwide media (eg, television, the Internet), but companies also directly target children in their own communities through the use of billboards and through local environments such as stores, restaurants, and schools. Given the harmful effect of this marketing environment on children's health and the industry's reluctance to make necessary changes to its food marketing practices, government at all levels has an obligation to act. This article focuses on policy options for municipalities that are seeking ways to limit harmful food marketing at the community level.

  1. Management options for food production systems affected by a nuclear accident. Task 3: diversion of crops grown for human consumption to animal feed

    2002-01-01

    This report forms part of a series describing a study to evaluate selected options for the management of food production systems affected by a nuclear accident. This report considers the scope for the redirection of contaminated foods grown for human consumption to animal feeds and addresses whether crops grown for human consumption can be used as animal feeds for animal production systems; what the likely impact on contamination levels in animal products is; whether amounts of waste food could be reduced in the event of a nuclear accident; and whether the option is acceptable to the farming industry, retail trade and consumers. The study identified that foods intended for human consumption can be used as animal feeds for beef cattle and sheep and, to a limited extent, for breeding sows but it is essential that a suitable nutritional balance is maintained. The scope to provide suitable alternative diets is, however, limited and is dependent upon the time of year at which the deposition occurs. If crops were contaminated at the relevant CFIL, not all of the alternative diets considered would result in animal products that were below the corresponding CFIL value, thus limiting any benefit in implementing the option. Except possibly in the most extreme of circumstances, this management option would not be considered acceptable by consumers or by the retail trade and farmers would only implement such a measure if there was a suitable market for the resultant produce. This work was undertaken under the Environmental Assessments Department and Emergency Response Group's Quality Management System, which has been approved by Lloyd's Register Quality Assurance to the Quality Management Standards ISO 9001:2000 and TickIT Guide Issue 5, certificate number 956546.

    In Maryland, county Food Protection Programs (FPP), housed within Environmental Public Health (EPH) Divisions, maintain responsibility for regular inspection of all food service facilities (FSF). With growing concerns about how our food supply is protected, it is important to determine the state and effectiveness of our food safety systems. This research elucidates the roles, responsibilities, strengths, and weaknesses of Food Safety and Protection Programs in Maryland. A 16-question survey tool, which addressed facets of the local food protection infrastructure, including FSF inspections, staffing, budget, and foodborne illness surveillance, was distributed to all 24 county FPP. The number of FSF in Maryland increased 97% from 2001 to 2006 and counties had an average inspection completion rate of 73%, with a 4% increase over the time period. Statewide, there were 4.1 EPH full-time employees (FTE) per 10 000 population and 1.6 FPP FTE per 10 000 population. EPH Division budgets increased 63% statewide, from $19.5 million in 2000 to $31.9 million in 2007. FPP budgets also increased 59% over the period, from $6.2 million in 2000 to $9.8 million in 2007. This study offers new quantitative measures of the demands, capacities, and performance of Food Protection and Safety Programs in Maryland. This assessment of local EPH and FPP capacity also offers insight into the strengths and weaknesses of the local food protection and safety infrastructure. Importantly, it reveals an infrastructure and dedicated food protection workforce that inspects the food supply and responds to foodborne illness outbreaks. Yet, resources vary substantially from county to county, impacting which services can be provided and how well they can be performed. This can, in turn, impact the potential risk of foodborne illness and the public's overall health.

    Full Text Available A glasshouse experiment was carried to identify effects of the application rate of ground silicate rock as a multinutrientfertilizer (SRF with and without organic matter (OM on growth and nutrient status of food crops (rice,corn, and soybean. Those crops were grown on 3 different soils in 2 cropping patterns, i.e., rice – soybean and corn– soybean, providing 6 experimental sets. A completely randomized design was applied in each experimental set.The treatment in each set consisted of 3 rates of SRF (5, 10, and 15 g kg-1, those 3 rates + 5 g kg-1 of OM, and acontrol (without adding SRF or OM. The first crops (rice and corn were grown up to 65 days, while the secondcrop (soybean was up to 40 days. Results indicated that for crops grown on less fertile soils, the application of SRFonly slightly increased growth of crops, mainly of the 2nd crops, and adding OM greatly increased the growth ofboth the 1st and 2nd crops. In those experimental sets, about 60 – 80% of the variation of crop growth was significantlydetermined by concentration of Cu and several other essential nutrients in crop tissue. In contrast, the growth forcrops grown on more fertile soils was not affected by the application of SRF or/and OM. It was concluded thatadding OM enhanced the effectiveness of SRF as a multi-nutrient fertilizer, and that may be used as an appropriatemulti-nutrient fertilizer or general ameliorant to sustain soil quality and remediate the nutritionally disorder soils.

    Emerging evidence has suggested aristolochic acids (AAs) are linked to the development of Balkan endemic nephropathy (BEN), a chronic renal disease affecting numerous farmers living in the Balkan peninsula. However, the pathway by which AAs enter the human food chain and cause kidney disease remains poorly understood. Using our previously developed analytical method with high sensitivity and selectivity (Chan, W.; Lee, K. C.; Liu, N.; Cai, Z. J. Chromatogr. A 2007, 1164, 113-119), we quantified AAs in lettuce, tomato, and spring onion grown in AA-contaminated soil and culture medium. Our study revealed that AAs were being taken up from the soil and bioaccumulated in food crops in a time- and dose-dependent manner. To the best of our knowledge, this study is the first to identify one of the possible pathways by which AAs enter our food chain to cause chronic food poisoning. Results also demonstrated that AAs were resistant to the microbial activity of the soil/water.

  7. Brazilian underutilised species to promote dietary diversity, local food procurement, and biodiversity conservation: a food composition gap analysis

    Directory of Open Access Journals (Sweden)

    Daniela Moura de Oliveira Beltrame, PhD

    2018-05-01

    Full Text Available Background: Brazil is home to a large portion of the world's biodiversity, but, paradoxically, the country's agriculture and food security are very reliant on exotic or introduced crops or species. Native species are being neglected and forgotten with natural landscapes and traditional foods being replaced by monocultures of commodity crops and pasture for livestock, causing habitat and biodiversity loss. At the same time, Brazil faces dietary simplification and high levels of malnutrition. Much of the neglected native biodiversity is highly nutritious and exploring these food sources could help provide sustainable solutions to diversifying diets, tackling malnutrition problems, and promoting agricultural development through local food procurement, while also promoting biodiversity conservation and climate change adaptation and resilience. However, notable knowledge and evidence gaps still need to be addressed to better integrate biodiversity for enhancing food and nutrition security, including scientific data on the nutritional value and composition of native underutilised species. In Brazil, the Biodiversity for Food and Nutrition (BFN project generated food composition data, developed recipes, and increased appreciation and awareness of the value of underutilised, nutrient-rich biodiversity through strategic research partnerships with universities and research institutes. Methods: For this food composition gap analysis of native Brazilian biodiversity, the BFN project established partnerships with universities and research institutes for the generation of food composition data (macronutrients, vitamins, and minerals and the development of recipes for 70 native underutilised species of fruits and vegetables of economic potential. Food composition data was gathered by doing a literature review, using compilation methods developed by the Food and Agriculture Organization of the United Nations and the International Network for Food Data Systems

  8. Public health promotion of "local food": Constituting the self-governing citizen-consumer.

    Science.gov (United States)

    Derkatch, Colleen; Spoel, Philippa

    2017-03-01

    This article explores how the recent and growing promotion of local foods by public health units in Ontario, Canada, rhetorically interpellates the "good" health citizen as someone who not only takes responsibility for personal health but, through the consumption and support of "local food," also accepts and fulfills her responsibilities to care for the local economy, the community's well-being, and the natural environment. Drawing on Charland's concept of constitutive rhetoric, we analyze a selection of public health unit documents about local food to develop a textured account of the complex, multifaceted forms of health citizenship they constitute. Our analysis reveals that, despite their appeals to environmental sustainability and community well-being, these materials primarily characterize the ideal health citizen as an informed consumer who supports the interests of the neoliberal state through individualized lifestyle behaviors, consuming goods produced and distributed through private enterprise. By exhorting individuals to "buy local," public health discourse therefore frames responsible health citizenship principally in consumerist terms that constrain the range of available options for citizens to engage in meaningful action vis-à-vis their food systems.

    Achieving nutritional requirements for pregnant and lactating mothers in rural households while maintaining the intake of local and culture-specific foods can be a difficult task. Deploying a linear goal programming approach can effectively generate optimal dietary patterns that incorporate local and culturally acceptable diets. The primary objective of this study was to determine whether a realistic and affordable diet that achieves nutritional goals for rural pregnant and lactating women can be formulated from locally available foods in Tanzania. A cross sectional study was conducted to assess dietary intakes of 150 pregnant and lactating women using a weighed dietary record (WDR), 24 h dietary recalls and a 7-days food record. A market survey was also carried out to estimate the cost per 100 g of edible portion of foods that are frequently consumed in the study population. Dietary survey and market data were then used to define linear programming (LP) model parameters for diet optimisation. All LP analyses were done using linear program solver to generate optimal dietary patterns. Our findings showed that optimal dietary patterns designed from locally available foods would improve dietary adequacy for 15 and 19 selected nutrients in pregnant and lactating women, respectively, but inadequacies remained for iron, zinc, folate, pantothenic acid, and vitamin E, indicating that these are problem nutrients (nutrients that did not achieve 100% of their RNIs in optimised diets) in the study population. These findings suggest that optimal use of local foods can improve dietary adequacy for rural pregnant and lactating women aged 19-50 years. However, additional cost-effective interventions are needed to ensure adequate intakes for the identified problem nutrients.

    The effect of the thermal annealing on the optical and spin properties in GaAs0.44Sb0.56 epilayers grown on InP was investigated via photoreflectance, power-dependent and time-resolved photoluminescence spectroscopy as well as optical orientation measurement. The carrier's localization and the optical spin detection efficiency increase with an increase of annealing temperature up to 600 °C. The enhancement of the spin detection efficiency is attributed to both the shortening of the electron lifetime and the prolonging of the spin lifetime as a result of the enhanced carriers' localization induced by the annealing process. Our results provided an approach to enhance spin detection efficiency of GaAsSb with its PL emission in the 1.55 μm region.

    Inadequate energy and micronutrient intake during childhood is a major public health problem in developing countries. Ready-to-use supplementary food (RUSF) made of locally available food ingredients can improve micronutrient status and growth of children. The objective of this study was to develop RUSF using locally available food ingredients and test their acceptability. A checklist was prepared of food ingredients available and commonly consumed in Bangladesh that have the potential of being used for preparing RUSF. Linear programming was used to determine possible combinations of ingredients and micronutrient premix. To test the acceptability of the RUSF compared to Pushti packet (a cereal based food-supplement) in terms of amount taken by children, a clinical trial was conducted among 90 children aged 6-18 months in a slum of Dhaka city. The mothers were also asked to rate the color, flavor, mouth-feel, and overall liking of the RUSF by using a 7-point Hedonic Scale (1 = dislike extremely, 7 = like extremely). Two RUSFs were developed, one based on rice-lentil and the other on chickpea. The total energy obtained from 50 g of rice-lentil, chickpea-based RUSF and Pushti packet were 264, 267 and 188 kcal respectively. Children were offered 50 g of RUSF and they consumed (mean ± SD) 23.8 ± 14 g rice-lentil RUSF, 28.4 ± 15 g chickpea based RUSF. Pushti packet was also offered 50 g but mothers were allowed to add water, and children consumed 17.1 ± 14 g. Mean feeding time for two RUSFs and Pushti packet was 20.9 minutes. Although the two RUSFs did not differ in the amount consumed, there was a significant difference in consumption between chickpea-based RUSF and Pushti packet (p = 0.012). Using the Hedonic Scale the two RUSFs were more liked by mothers compared to Pushti packet. Recipes of RUSF were developed using locally available food ingredients. The study results suggest that rice-lentil and chickpea-based RUSF are well accepted

    Full Text Available The aim of this paper is to assess if there is a difference in food choice behaviour between regular customers of stores of the retail chain Terno and other consumers. Consequently, the paper aims to discover, if the strategy formulated by the consumer co-operative Jednota České Budějovice was a good strategy. The core of this strategy is the orientation on the region, local and regional food and food products and the co-operation with local small and medium suppliers. Another part of this strategy is also the permanent control of quality of these products and creation of the special private label – Quality food from our region. The consumer co-operative co-operates also with the regional grouping under another label – Tastes great. Southbohemian. The assessment is done by means of the analysis of a questionnaire survey that was done among consumers in the South Bohemia in 2011. The strongest factor differentiating customers of the retail chain TERNO from other consumer is the orientation on regional or local products, which explains about 41% of variability. Other differentiating factors are environment-friendly production and selling and quality of food. All these three factors explain in total 66.5% of variability of the data set.

    In collaboration with Public Health Practice-Based Research Networks, we investigated relationships between local health department (LHD) food safety and sanitation expenditures and reported enteric disease rates. We combined annual infection rates for the common notifiable enteric diseases with uniquely detailed, LHD-level food safety and sanitation annual expenditure data obtained from Washington and New York state health departments. We used a multivariate panel time-series design to examine ecologic relationships between 2000-2010 local food safety and sanitation expenditures and enteric diseases. Our study population consisted of 72 LHDs (mostly serving county-level jurisdictions) in Washington and New York. While controlling for other factors, we found significant associations between higher LHD food and sanitation spending and a lower incidence of salmonellosis in Washington and a lower incidence of cryptosporidiosis in New York. Local public health expenditures on food and sanitation services are important because of their association with certain health indicators. Our study supports the need for program-specific LHD service-related data to measure the cost, performance, and outcomes of prevention efforts to inform practice and policymaking.

    2016-01-25

    By importing food and agricultural goods, countries cope with the heterogeneous global water distribution and often rely on water resources available abroad. The virtual displacement of the water used to produce such goods (known as virtual water) connects together, in a global water system, all countries participating to the international trade network. Local food-production crises, having social, economic or environmental origin, propagate in this network, modifying the virtual water trade and perturbing local and global food availability, quantified in terms of virtual water. We analyze here the possible effects of local crises by developing a new propagation model, parsimonious but grounded on data-based and statistically-verified assumptions, whose effectiveness is proved on the Argentinean crisis in 2008-09. The model serves as the basis to propose indicators of crisis impact and country vulnerability to external food-production crises, which highlight that countries with largest water resources have the highest impact on the international trade, and that not only water-scarce but also wealthy and globalized countries are among the most vulnerable to external crises. The temporal analysis reveals that global average vulnerability has increased over time and that stronger effects of crises are now found in countries with low food (and water) availability.

    A probiotic dairy product was developed on the basis of a traditional dish called mutandabota to enable resource-poor populations in southern Africa to benefit from a functional food. Mutandabota is widely consumed in rural southern Africa, making it an ideal food matrix to carry probiotics. First, a process to produce probiotic mutandabota was designed. Raw cow milk was boiled and subsequently cooled to ambient temperature (25°C). Next, dry pulp from the fruit of the baobab tree (Adansonia digitata L.) was added to the milk at a concentration of 4% (wt/vol). This mixture was inoculated with the probiotic Lactobacillus rhamnosus yoba and left to ferment for 24h, while the growth of the bacterial culture was monitored. Final ingredients were then added to produce probiotic mutandabota that had 14% (wt/vol) baobab fruit pulp and 7% (wt/vol) sugar in cow milk. The pH of probiotic mutandabota was pH 3.5, which ensures that the product is microbiologically safe. The viable plate count of L. rhamnosus yoba increased from 5.8 ± 0.3 log cfu/mL at the point of inoculation to 8.8 ± 0.4 log cfu/mL at the moment of consumption, thereby meeting the criterion to have a viable count of the probiotic bacterium in excess of 6 log cfu/mL of a product. Baobab fruit pulp at 4% promoted growth of L. rhamnosus yoba with a maximal specific growth rate (μmax) of 0.6 ± 0.2/h at 30°C. The developed technology, though specific for this particular product, has potential to be applied for the delivery of probiotics through a variety of indigenous foods in different regions of the world. Upon consumption, probiotic mutandabota is expected to improve the population's intestinal health, which is especially relevant for vulnerable target groups such as children and elderly people.

    Smartphone “apps” are a powerful tool for public health promotion, but unidimensional interventions have been ineffective at sustaining behavioural change. Various logistical issues exist in successful app development for health intervention programs and for sustaining behavioural change. This study reports on a smartphone application and messaging service, called “SmartAPPetite,” which uses validated behaviour change techniques and a behavioural economic approach to “nudge” users into healthy dietary behaviours. To help gauge participation in and influence of the program, data were collected using an upfront food survey, message uptake tracking, experience sampling interviews, and a follow-up survey. Logistical and content-based issues in the deployment of the messaging service were subsequently addressed to strengthen the effectiveness of the app in changing dietary behaviours. Challenges included creating relevant food goal categories for participants, providing messaging appropriate to self-reported food literacy and ensuring continued participation in the program. SmartAPPetite was effective at creating a sense of improved awareness and consumption of healthy foods, as well as drawing people to local food vendors with greater frequency. This work serves as a storehouse of methods and best practices for multidimensional local food-based smartphone interventions aimed at improving the “triple bottom line” of health, economy, and environment.

    "Think global, act local" is a phrase often used in sustainability debates. Here, we explore the potential of regions to go for local supply in context of sustainable food consumption considering both the present state and the plausible future scenarios. We analyze data on the gridded crop calories production, the gridded livestock calories production, the gridded feed calories use and the gridded food calories consumption in 5' resolution. We derived these gridded data from various sources: Global Agro-ecological Zone (GAEZ v3.0), Gridded Livestock of the World (GLW), FAOSTAT, and Global Rural-Urban Mapping Project (GRUMP). For scenarios analysis, we considered changes in population, dietary patterns and possibility of obtaining the maximum potential yield. We investigate the food self-sufficiency multiple spatial scales. We start from the 5' resolution (i.e. around 10 km x 10 km in the equator) and look at 8 levels of aggregation ranging from the plausible lowest administrative level to the continental level. Results for the different spatial scales show that about 1.9 billion people live in the area of 5' resolution where enough calories can be produced to sustain their food consumption and the feed used. On the country level, about 4.4 billion population can be sustained without international food trade. For about 1 billion population from Asia and Africa, there is a need for cross-continental food trade. However, if we were able to achieve the maximum potential crop yield, about 2.6 billion population can be sustained within their living area of 5' resolution. Furthermore, Africa and Asia could be food self-sufficient by achieving their maximum potential crop yield and only round 630 million populations would be dependent on the international food trade. However, the food self-sufficiency status might differ under consideration of the future change in population, dietary patterns and climatic conditions. We provide an initial approach for investigating the

    Full Text Available Arsenic contamination in a large area of agricultural fields on the Guandu Plain of northern Taiwan was confirmed in a survey conducted in 2006, but research concerning the relationship between bioavailable As concentrations in contaminated soils and crop production in Taiwan is not available. Pot experiments were conducted to examine the growth and accumulation of As in four vegetable crops grown in As-contaminated soils and to assess As intake through consumption. The phytotoxic effects of As in soils were not shown in the pot experiments in which vegetable crops were grown in soils contaminated with different As levels in situ collected from Guandu Plain (120–460 mg/kg or artificially spiked As-contaminated soils (50–170 mg/kg. Experimental results showed that the bioavailable As extracted with 0.5M NaHCO3 from soils can be used to estimate As concentrations in vegetables. The As concentrations in the vegetables were compared with data shown in the literature and As limits calculated from drinking water standards and the provisional tolerance weekly intake (PTWI of inorganic As established by the Food and Agriculture Organization of the United Nations/World Health Organization (FAO/WHO. Although the As levels in the vegetables were not high and the bioavailability of As in the soils was quite low, long-term consumption may result in higher As intake in the human body.

  6. Recent experiences in the development of locally-produced ready to use foods

    2014-01-01

    Ready-to-use foods for treatment of moderate acute malnutrition (MAM) are micronutrient-fortified, lipid pastes containing roasted peanuts, oil, micronutrients, sugar, soy and/or dairy ingredient powders. The benefits of pastes like ready-to-use therapeutic food (RUTF), ready-to-use supplementary food (RUSF), and lipid nutrient supplements (LNS) for the treatment of nutritional maladies are that they are shelf-stable due to their low water activity, they are easily transportable, and they can be eaten as-is. Since the development of ready-to-use foods, cost reduction and local production experimentation have been ongoing. Attempts to replace ingredients like skim milk powder with alternate dairy protein ingredients or non-animal ingredients have been reported, but little food and process development information has been revealed. Linear programming or least-cost optimization mathematical models have been employed to help design low cost paste formulas from a selection of ingredients that also meet nutritional requirements. A new user-friendly tool can be used to develop new formulas that incorporate locally-sourced ingredients. New approaches to ingredient utilization are necessary for future ready-to-use food production and will require the development of novel processes for local ingredients compared to traditional pastes. The challenges of incorporating novel ingredients include processing changes, flavor and acceptability, and meeting nutrient requirements. Our research is designed to not only look at substitute ingredients, but also to optimize processing conditions in order to reduce cost by energy savings, extended shelf-life, and lower nutrient degradation. An RUSF using a novel dairy ingredient, whey permeate, was recently developed and is currently being tested in a prospective, double-blind randomized clinical trial for children with MAM in Malawi. Recent research in the development and testing of ready-to-use foods for MAM include a programmatic study

    Full Text Available Diet is a modifiable contributor to many chronic diseases including childhood obesity. The local food environment may influence children's diet but this area of research is understudied. This study explores if distance to and the number of supermarkets and convenience stores in the local area around households are associated with dietary quality in nine year olds whilst controlling for household level socio-economic factors. This is a secondary analysis of Wave 1 (2007/2008 of the Growing Up in Ireland (GUI Child Cohort Study, a sample of 8568 nine year olds from the Republic of Ireland. Dietary intake was assessed using a short, 20-item parent reported food frequency questionnaire and was used to create a dietary quality score (DQS whereby a higher score indicated a higher diet quality. Socio-economic status was measured using household class, household income, and maternal education. Food availability was measured as road network distance to and the number of supermarkets and convenience stores around households. Separate fixed effects regression models assessed the association between local area food availability and dietary quality, stratified by sex. The DQS ranged from −5 to 25 (mean 9.4, SD 4.2. Mean DQS was higher in those who lived furthest (distance in quintiles from their nearest supermarket (p<0.001, and in those who lived furthest from their nearest convenience store (p<0.001. After controlling for socio-economic characteristics of the household, there was insufficient evidence to suggest that distance to the nearest supermarket or convenience store was associated with dietary quality in girls or boys. The number of supermarkets or convenience stores within 1000 m of the household was not associated with dietary quality. Food availability had a limited effect on dietary quality in this study. Issues associated with conceptualising and measuring the food environment may explain the findings of the current study. Keywords: Diet

    Little is known about the dynamics of the food outlet distributions associated with local contextual factors in the U.S. This study examines the changes in food stores/services at the 5-digit Zip Code Tabulated Area (ZCTA5) level in the U.S., and assesses contextual factors associated with the changes. Data from 27,878 ZCTA5s in the contiguous United States without an extreme change in the number of 6 types of food stores/services (supermarkets, small-size grocery stores, convenience stores, fresh/specialty food markets, carry-out restaurants, and full-service restaurants) were used. ZCTA5s' contextual factors were from the 2000 Census. Numbers of food stores/services were derived from the Census Business Pattern databases. Linear regression models assessed contextual factors' influences (racial/ethnic compositions, poverty rate, urbanization level, and foreign-born population%) on 1-year changes in food stores/services during 2000-2001, adjusted for population size, total business change, and census regions. Small-size grocery stores and fresh/specialty food markets increased more and convenience stores decreased more in Hispanic-predominant than other areas. Among supermarket-free places, new supermarkets were less likely to be introduced into black-predominant than white-predominant areas (odds ratio (OR) = 0.52, 95% CI = 0.30-0.92). However, among areas without the following type of store at baseline, supermarket (OR = 0.48 (0.33-0.70)), small-size grocery stores (OR = 1.32 (1.08-1.62)), and fresh/specialty food markets (OR = 0.70 (0.53-0.92)) were less likely to be introduced into areas of low foreign-born population than into areas of high foreign-born population. Higher poverty rate was associated with a greater decrease in supermarket, a less decrease in small-size grocery stores, and a less increase in carry-out restaurants (all p for trends restaurants than suburban areas.

    Contaminants of emerging concern present in domestic waste streams include a highly diverse group of potentially biologically active compounds that can be detected at trace levels in wastewater. Concerns about potential uptake into crops arise when reclaimed water is used in food crop production. The present study investigated how 9 contaminants of emerging concern in reclaimed water are taken up into edible portions of two food crops. Two flame retardant chemicals, tris(1-chloro-2-propyl) phosphate (TCPP) and tris(2-chloroethyl) phosphate (TCEP) and several polar pharmaceuticals (carbamazepine, diphenhydramine, sulfamethoxazole, and trimethoprim) accumulated in a linear, concentration-dependent manner in lettuce (Lactuca sativa) irrigated with reclaimed water, suggesting passive uptake of both neutral and ionizable chemical contaminants in lettuce. Furthermore, concentration-dependent accumulation of TCEP and TCPP from reclaimed water was also observed in strawberry fruits (Fragaria ananassa). Collectively, these data suggest that highly polar or charged contaminants can be taken up by crops from water bearing contaminants of emerging concern and can be accumulated in the edible portions. Using these data, however, estimates of human exposure to these contaminants from reclaimed water food crop accumulation suggest that exposure to the contaminants of emerging concern examined in the present study is likely substantially lower than current exposure guidelines. © 2015 SETAC.

    We report on the dimensional crossover of electron weak localization in ZnO/TiO{sub x} stacked layers having well-defined and spatially-localized Ti dopant profiles along film thickness. These films were grown by in situ incorporation of sub-monolayer TiO{sub x} on the growing ZnO film surface and subsequent overgrowth of thin conducting ZnO spacer layer using atomic layer deposition. Film thickness was varied in the range of ∼6–65 nm by vertically stacking different numbers (n = 1–7) of ZnO/TiO{sub x} layers of nearly identical dopant-profiles. The evolution of zero-field sheet resistance (R{sub ◻}) versus temperature with decreasing film thickness showed a metal to insulator transition. On the metallic side of the metal-insulator transition, R{sub ◻}(T) and magnetoresistance data were found to be well corroborated with the theoretical framework of electron weak localization in the diffusive transport regime. The temperature dependence of both R{sub ◻} and inelastic scattering length provided strong evidence for a smooth crossover from 2D to 3D weak localization behaviour. Results of this study provide deeper insight into the electron transport in low-dimensional n-type ZnO/TiO{sub x} stacked layers which have potential applications in the field of transparent oxide electronics.

    Local invariant features have shown to be successful in describing object appearances for image classification tasks. Such features are robust towards occlusion and clutter and are also invariant against scale and orientation changes. This makes them suitable for classification tasks with little inter-class similarity and large intra-class difference. In this paper, we propose an integrated representation of the Speeded-Up Robust Feature (SURF) and Scale Invariant Feature Transform (SIFT) descriptors, using late fusion strategy. The proposed representation is used for food recognition from a dataset of food images with complex appearance variations. The Bag of Features (BOF) approach is employed to enhance the discriminative ability of the local features. Firstly, the individual local features are extracted to construct two kinds of visual vocabularies, representing SURF and SIFT. The visual vocabularies are then concatenated and fed into a Linear Support Vector Machine (SVM) to classify the respective food categories. Experimental results demonstrate impressive overall recognition at 82.38% classification accuracy based on the challenging UEC-Food100 dataset.

    Development production of Indonesia local cattle didn’t balance increasing of consumption livestock in Indonesian so that’s makes imports are still high both local beef production. Indonesian local cattle is one of cattle the largest contributed the national meat production of ruminant particular group of cattle so that the livestock has the potential to be developed as a profitable business if doing of farmer. One of advantages is potential areas in South Kalimantan mainly swamp lands was very large. It’s one effort in national promoting food sovereignty programme and the provinces especially about introduction of Indonesian local cattle in the swamp area are also important. Availability of region in South Kalimantan spacious and great forage production, then prospects for cattle productivity there is huge so that’s can even increase income for farmers. The programme more serious support from the governance of South Kalimantan province to develop Indonesian local cattle in swamp area and in that’s a real policy for encouraging farmers to maintain Indonesian local cattle to make sustainable food in Indonesia.

  14. Laser Scribed Graphene Biosensor for Detection of Biogenic Amines in Food Samples Using Locally Sourced Materials

    Full Text Available In foods, high levels of biogenic amines (BA are the result of microbial metabolism that could be affected by temperatures and storage conditions. Thus, the level of BA is commonly used as an indicator of food safety and quality. This manuscript outlines the development of laser scribed graphene electrodes, with locally sourced materials, for reagent-free food safety biosensing. To fabricate the biosensors, the graphene surface was functionalized with copper microparticles and diamine oxidase, purchased from a local supermarket; and then compared to biosensors fabricated with analytical grade materials. The amperometric biosensor exhibits good electrochemical performance, with an average histamine sensitivity of 23.3 µA/mM, a lower detection limit of 11.6 µM, and a response time of 7.3 s, showing similar performance to biosensors constructed from analytical grade materials. We demonstrated the application of the biosensor by testing total BA concentration in fish paste samples subjected to fermentation with lactic acid bacteria. Biogenic amines concentrations prior to lactic acid fermentation were below the detection limit of the biosensor, while concentration after fermentation was 19.24 ± 8.21 mg histamine/kg, confirming that the sensor was selective in a complex food matrix. The low-cost, rapid, and accurate device is a promising tool for biogenic amine estimation in food samples, particularly in situations where standard laboratory techniques are unavailable, or are cost prohibitive. This biosensor can be used for screening food samples, potentially limiting food waste, while reducing chances of foodborne outbreaks.

    Frank’s theory describes that a screw dislocation will produce a pit on the surface, and has been evidenced in many material systems including GaN. However, the size of the pit calculated from the theory deviates significantly from experimental result. Through a careful observation of the variations of surface pits and local surface morphology with growing temperature and V/III ratio for c -plane GaN, we believe that Frank’s model is valid only in a small local surface area where thermodynamic equilibrium state can be assumed to stay the same. If the kinetic process is too vigorous or too slow to reach a balance, the local equilibrium range will be too small for the center and edge of the screw dislocation spiral to be kept in the same equilibrium state. When the curvature at the center of the dislocation core reaches the critical value 1/ r 0 , at the edge of the spiral, the accelerating rate of the curvature may not fall to zero, so the pit cannot reach a stationary shape and will keep enlarging under the control of minimization of surface energy to result in a large-sized surface pit.

    Highlights: We have elaborately explained the individual Ge QD charging phenomena and current transport, which is very important to understand the Ge/Si nano devices. This paper will give a flavor to properly understand these phenomena linked together along with the photocurrent mechanism which is related to the Ge/Si valence band offset. • Both the CAFM and KPFM techniques point out the functionality of doping nature of the underneath Si substrate on the aforementioned characteristics of Ge QDs. • Analysis of the surface potential mapping using KPFM technique yields an approximate valence band offset measurement which is required to understand the intra-valence transition of holes for the realization of long wavelength infrared photodetector. • KPFM and CAFM can be utilized to explore the charging/discharging phenomena of dots and their composition variations. • Current-voltage (I–V) characteristics of the individual Ge QD strongly depends on the individual QD size. • Energy band diagrams for diamond tip and Ge QD shows the higher barrier for electrons and lower barrier for holes allowing the easy tunneling for holes to dominate the transport. - Abstract: It is fundamentally important to understand the nanoscale electronic properties of a single quantum dot (QD) contrary to an ensemble of QDs. Kelvin probe force microscopy (KPFM) and conductive atomic force microscopy (CAFM) are two important tools, which could be employed to probe surface potential, charging phenomena, and current transport mechanism of individual QD. We demonstrate the aforementioned characteristics of self-assembled Ge QDs, which was grown on Si substrates by solid source molecular beam epitaxy driven by the Stranski-Krastanov method. Study reveals that each Ge QD acts as charge storage node even at zero applied bias. The shape, size and density of QDs could be well probed by CAFM and KPFM, whereas QD facets could be better resolved by the conductive tip. The CAFM investigation

    We recently reported an independent association between IgE sensitization to food allergens and increased airway inflammation, assessed by fraction of exhaled nitric oxide (FeNO), in a population-based study (J Allergy Clin Immunol, 130, 2012, 397). Similar studies have not been performed in populations with asthma. The aim of the present study was to investigate the allergic sensitization profile in asthmatics and examine FeNO, airway responsiveness and blood eosinophilia in relation to type and degree of IgE sensitization. FeNO, airway responsiveness, blood eosinophil count (B-Eos) and IgE sensitization to food allergens and aeroallergens were determined in 408 subjects with asthma, aged 10-34 years. Asthmatics had higher prevalence of IgE sensitization against all allergens than controls (P < 0.001). Mite, pollen, furry animal, mould and food sensitizations were each associated with increased FeNO, airway responsiveness and B-Eos in asthmatics. IgE sensitization to mould, furry animals and food allergens was independently related to FeNO (all P < 0.05) after adjustment for age, sex, height, smoking history and medication. IgE sensitization to mould (P < 0.001) and furry animals (P = 0.02) was related to airway responsiveness in a similar model. Finally, IgE sensitization to mould (P = 0.001), furry animals (P < 0.001) and food allergens (P < 0.001) was independently related to B-Eos. Independent effects of IgE sensitization to aeroallergens (furry animals and mould) and food allergens were found on both local and systemic markers of inflammation in asthma. The finding regarding food IgE sensitization is novel, and a clinical implication might be that even food sensitization must be assessed to fully understand inflammation patterns in asthma. © 2014 John Wiley & Sons A/S.

    Studies investigating the connection between environmental factors and migration are difficult to execute because they require the integration of microdata and spatial information. In this article, we introduce the novel, publically available data extraction system Terra Populus (TerraPop), which was designed to facilitate population-environment studies. We showcase the use of TerraPop by exploring variations in the climate-migration association in Burkina Faso and Senegal based on differences in the local food security context. Food security was approximated using anthropometric indicators of child stunting and wasting derived from Demographic and Health Surveys (DHS) and linked to the TerraPop extract of climate and migration information. We find that an increase in heat waves was associated with a decrease in international migration from Burkina Faso, while excessive precipitation increased international moves from Senegal. Significant interactions reveal that the adverse effects of heat waves and droughts are strongly amplified in highly food insecure Senegalese departments. PMID:27974863

    Full Text Available Considering the wide demand for daily meals, the issue of the institutional food system has become very important in highly developed societies and, also, how it affects the flow of energy and matter within a territory. This research originates from a wide multi-disciplinary project aimed at developing a self-sufficient approach to improve the institutional food system in an area of Northern Italy. Thus, the aim of this research is to give some guidelines to implement ideal scenarios of food production, processing, consumption, and waste management at the local level. To that end, the organization of the supply and demand within the local institutional food system is inquired. A methodology has been developed to analyze the main energy flows and matter related to this catering, and to outline possible optimal scenarios. This methodology also allows to analyze case studies and to formulate improvements in order to reduce their energy consumption while exploring all the steps of the supply chain (considering the Life Cycle Assessment (LCA approach. The use of quantitative indicators allows a comparison of the impacts related to the different steps characterizing the suggested scenarios. This paper presents results related to a test in the context of institutional catering in public schools.

    Fifteen non-insulin dependent diabetic volunteers, aged 51 +/- 3.9 years, were studied over a two month period to determine their glycaemic responses to various local foods. They were all on chlorpropamide and one subject was removed from analysis due to concurrent use of insulin. They received on separate occasions two servings of white bread, one serving of: brown bread, white lice, English potatoes, maize meal, millet and cassava each. Each meal contained 50 g of carbohydrate. A total of 107 glucose tolerance tests (GTTs) were performed and the glycaemic index (GI) for each food calculated. The mean blood sugars at 0,60 and 120 minutes were comparable for each food, and the peak rise occurred at 60 minutes. The highest rise (4.0 mmol/I) was seen with millet porridge. The highest GI was seen with white rice and the lowest with English potatoes (159.9 and 34.3 respectively). Overall, the cereals conferred higher GIs than the root vegetables. The GIs of English potatoes, maize meal, millet and cassava significantly differed from that of white bread. It is concluded that, using GIs, dietary guidelines comprising locally available and affordable foods can be made.

    Titanium dioxide (TiO 2 ) thin films were synthesized on (1 0 0) Si substrates by reactive pulsed laser deposition (PLD) technique. A frequency quadrupled Nd : YAG (λ = 266 nm, τ FWHM ≅ 5 ns, ν = 10 Hz) laser source was used for the irradiations of metallic Ti targets. The experiments were performed in controlled oxygen atmosphere. Crystallinity, surface morphology and local electric properties of the obtained oxide thin films were investigated by x-ray diffractometry, micro-Raman spectroscopy and current sensing atomic force microscopy. An inter-relation was found between the surface morphology, the crystalline structure and the nano-scale electric properties which open the possibility of synthesizing by the PLD technique TiO 2 thin films with tunable functional properties for future applications such as photocatalysts, gas sensors or solar energy converters

    Full Text Available Sustainability assessment is one of the keys to competition by food supply chains over sustainability. The way it is conceived and embodied into decision-makers’ choices affects the competitiveness of local and global chains. Science-based assessment methodologies have made substantial progress, but uncertainties—as well as interests at stake—are high. There are no science-based methods that are able to give an unchallenged verdict over the sustainability performance of a firm, let alone a supply chain. Assessment methods are more suited for medium-large firm dimensions, as planning, monitoring, and reporting are costly. Moreover, the availability of data affects the choice of parameters to be measured, and many claims of local food are not easily measurable. To give local chains a chance to operate on a level playing field, there is the need to re-think sustainability assessment processes and tailor them to the characteristics of the analysed supply chains. We indicate seven key points on which we think scholars should focus their attention when dealing with food supply chain sustainability assessment.

    The effects of different concentrations of soil cadmium (0, 1, 3, 5, 10, and 20 mg kg{sup -1}) on growth, structural changes and cadmium cellular localization in leaves of maize plants (Zea mays L.) were investigated in a pot experiment. The results showed that the structural changes observed in maize leaves were not only a response to the Cd-induced stress but also a cellular mechanism to reduce the free Cd{sup +2} in the cytoplasm. However, this mechanism seems to be efficient only up to a Cd concentration in leaves between 27 and 35 mg kg{sup -1} for soils without and with liming, respectively. The cellular response varied with both the Cd concentration in soil and liming. For limed soil, Cd was preferentially accumulated in the apoplast while for unlimed soils Cd was more evenly distributed into the cells. The ability of Cd accumulation depended on the leaf tissue considered. The apoplast collenchyma presented the highest Cd concentration followed by the endodermis, perycicle, xylem, and epidermis. On the other hand, symplast Cd accumulated mainly in the endodermis, bundle sheath cells, parenchyma, and phloem. Based on the structural changes and growth reduction, the critical toxic concentration of soil Cd to maize plants is between 5 and 10 mg kg{sup -1}.

Fondé sur l’analyse de données et d’interviews avec les acteurs clés investis dans ces deux réseaux (qui représentent des mentalités alimentaires très différentes cet article montre que, contrairement à ce qui prévaut dans la littérature scientifique des systèmes agro-alimentaires, la notion d’« entrelacement social » n’est pas une caractéristique donnée. Elle résulte d’un procédé dynamique d’attribution de sens à travers lequel les acteurs sociaux construisent et défendent la relation entre le produit et le lieu. Cette perspective met en valeur l’aspect compliqué des notions de « territorialité » et de « localisation », et soulève d’importantes questions à propos de la durabilité des systèmes alimentaires locaux.This article explores the meanings and implications of the notion of embeddedness through a focus on two emerging local food systems: saffron in Tuscany and Steve Turton meats in the South West of England. Based on the analysis of documentary material and of the narratives of key actors operating within two different food cultures, the article shows that, contrary to prevailing interpretations in the agri-food literature, embeddedness is not a given characteristic of some food systems. Quite the contrary, embeddedness of local food products results from a dynamic process of attribution of meanings through which social actors construct and defend the connection between a product and a place. In addition to complicating notions of ‘territoriality’ and food ‘relocalization’, this perspective raises important questions about the sustainability of local food systems.

    Raw milk, raw fruit juice and raw fish are enriched with essential nutrients for human diet but are prone to microbial contamination along the value chain. This cross sectional study was conducted to assess physicochemical characteristics and microbial quality of raw milk, fruit juice and fish from food vendors in Morogoro Municipality, Tanzania. The physicochemical assessment of food samples was done by smell, colour, presence of debris, turbidity, consistence, pH and clot on alcohol test. Hygiene of food containers, personnel and the vending environment was also assessed. Qualitative and quantitative microbial assessment of food was done using standard laboratory protocols as described by Tanzania Bureau of Standards and International Systems of Standards. Raw milk sold in Morogoro was of poor quality since was adulterated with water, contained sediments and clotted on alcohol test. Up to 63 % of the milk samples were contaminated with Escherichia coli and 60 % had higher total viable count (TVC) than the recommended values. Raw fruit juice was stored in dirty containers and sold under unhygienic environment. Seventy-three percent of juice samples had TVC beyond the recommendations while E. coli contamination rate was 63.3 %. The raw fish samples had started spoiling as depicted through sensory evaluation. E. coli contamination rate was 55 % and that of Campylobacter jejuni was 0.5 %. The mean TVC of raw fish was 8.1 (Log cfu/g) and 96.2 % of the fish samples had TVC beyond the recommended limits of 5.0 Log cfu/g. The physicochemical characteristics of food vended in Morogoro Municipality were of poor quality. The food had high bacterial contaminations. This situation poses health risks to the public and losses to food vendors due to spoilage. Stakeholders in food value chain should be educated on safe production and good hygienic practices.

Personal footprints include the water embedded in foods that are produced locally as well as those imported, raising the question of whether local shifts in people's food choices and habits could assist in addressing local water shortages. The current situation in California is interesting in that drought has affected an agriculturally productive region where a substantial portion of its food products are consumed by the state's large population. Unlike most agricultural regions where green water is the primary source of water for crops, California's arid climate demands an enormous volume of blue water as irrigation from its dwindling surface and ground water resources. Although California exports many of its food products, enough is consumed in-state so that residents making relatively minor shifts their food choices could save as much local blue water as their implementing more drastic reductions in household water use (comprising food group on both a caloric and gravimetric basis. Another change is wasting less food, which is a shared responsibility among consumers, producers and retailers; however, consumers' actions and preferences ultimately drive much of the waste. Personal water footprints suggest a role for individuals in conserving local water resources that is neither readily obvious nor a major focus of most conservation programs.

    Food guides are important tools for nutrition education. While developing a food guide in Benin, the objective was to determine the daily number of servings per food group and the portion sizes of common foods to be recommended. Linear programming (LP) was used to determine, for each predefined food group, the optimal number and size of servings of commonly consumed foods. Two types of constraints were introduced into the LP models: (i) WHO/FAO Recommended Nutrient Intakes and dietary guidelines for the prevention of chronic diseases; and (ii) dietary patterns based on local food consumption data recently collected in southern Benin in 541 adults. Dietary intakes of the upper tertile of participants for diet quality based on prevention and micronutrient adequacy scores were used in the LP algorithms. Southern area of the Republic of Benin. Local key-players in nutrition (n 30) from the government, academic institutions, international organizations and civil society were partners in the development of the food guide directed at the population. The number of servings per food group and the portion size for eight age-sex groups were determined. For four limiting micronutrients (Fe, Ca, folate and Zn), local diets could be optimized to meet only 70 % of the Recommended Nutrient Intakes, not 100 %. It was possible to determine the daily number of servings and the portion sizes of common foods that can be recommended in Benin with the help of LP to optimize local diets, although Recommended Nutrient Intakes were not fully met for a few critical micronutrients.

    Full Text Available Indonesia is the third richest country for pigmented rice source such as Wojalaka black rice of East Nusa Tenggara (NTT, Manggarai of NTT, Toraja of South Sulawesi, Cempo Ireng of Central Java and red rice of Aek Sibundong (leading variety and Baubau of Southeast Sulawesi. However, the morphological character of pigmented rice in Indonesia is less reported. The objective of research was to compare the morphological variation of root, stem, leaf, panicle, floret and the colour of milk mature grain and mature grain by observing the vegetative and generative parts of six local rice varieties. Research had been conducted from February 2012 to February 2014 in Sengguruh Village, Kepanjen District, Malang Regency. This study type was quasi-experiment with eleven replications. Group Random Design was used. The observation was given upon vegetative, reproductive and maturity phases as groups. Independent variables in this study were six rice varieties, while the dependent variable was morphological variation (root, stem, leaf, panicle, floret, milk mature grain and mature grain. The analysis of multivariate data in cluster and bip lot was carried out with PAST. The result of the study indicated that there was morphological difference on stem, leaf, panicle, floret, milk mature grain and mature grain. The colour of the stem in Aek Sibundong variety was purple, while that of other varieties was green. Toraja and Manggarai varieties had the highest height with 163-168 cm, followed by Cempo Ireng with 139 cm, Wojalaka and Baubau with 110-112 cm. Aek Sibundong Variety had the lowest height with 99 cm. Aek Sibundong and Wojalaka varieties had 6-7 internodes which were the greatest number of internode, while other varieties only had 4-5 internodes. Some varieties, such as Aek Sibundong, Wojalaka and Baubau had short and small leaf. The leaflet angle of Aek Sibundong and Baubau were 14o and it might be said as upright, while that of Wojalaka was 43o or moderate

    Background Little is known about the dynamics of the food outlet distributions associated with local contextual factors in the U.S. This study examines the changes in food stores/services at the 5-digit Zip Code Tabulated Area (ZCTA5) level in the U.S., and assesses contextual factors associated with the changes. Methods Data from 27,878 ZCTA5s in the contiguous United States without an extreme change in the number of 6 types of food stores/services (supermarkets, small-size grocery stores, convenience stores, fresh/specialty food markets, carry-out restaurants, and full-service restaurants) were used. ZCTA5s’ contextual factors were from the 2000 Census. Numbers of food stores/services were derived from the Census Business Pattern databases. Linear regression models assessed contextual factors’ influences (racial/ethnic compositions, poverty rate, urbanization level, and foreign-born population%) on 1-year changes in food stores/services during 2000–2001, adjusted for population size, total business change, and census regions. Results Small-size grocery stores and fresh/specialty food markets increased more and convenience stores decreased more in Hispanic-predominant than other areas. Among supermarket-free places, new supermarkets were less likely to be introduced into black-predominant than white-predominant areas (odds ratio (OR) = 0.52, 95% CI = 0.30-0.92). However, among areas without the following type of store at baseline, supermarket (OR = 0.48 (0.33-0.70)), small-size grocery stores (OR = 1.32 (1.08-1.62)), and fresh/specialty food markets (OR = 0.70 (0.53-0.92)) were less likely to be introduced into areas of low foreign-born population than into areas of high foreign-born population. Higher poverty rate was associated with a greater decrease in supermarket, a less decrease in small-size grocery stores, and a less increase in carry-out restaurants (all p for trends <0.001). Urban areas experienced more increases in full

    The food provision system of today has been argued to be unsustainable with large scale production, price-pressure and outbreaks of diseases. Many consumers in the EU and Sweden are reacting to these issues and are becoming increasingly interested in finding local food alternatives that they consider to be safer and of higher quality. However, the small local food producers due to scarce budgets and marketing skills have problems in reaching this target market. Partly due to this, there has b...

    Food technology transfer to rural households, based on local ingredients, is a relevant and sustainable strategy to ensure better nutrition of young children. Objective. To develop an improved mush based on local ingredients and evaluate the potential for transferring its technology to rural housewives. We developed a flour-based food using Alicom software and performed laboratory trials to evaluate its actual nutritional quality. Then we recruited housewives from each of the 27 project villages and trained them in flour production and mush preparation twice daily, 6 days a week, for 26 weeks. Mush was sampled during the training session and at weeks 4, 12, and 22 and evaluated for actual flow distance and dry matter content, which served to estimate energy density and iron and zinc contents. The laboratory trials reported average energy densities of 103 kcal/l00 g, iron contents of 2.6 mg/100 kcal, and zinc contents of 1.2 mg/100 kcal. The average (+/- SD) energy densities of the mush samples obtained during the training session and at weeks 4, 12, and 22 were 103.0 +/- 5.6, 103.3 +/- 5.2, 107.9 +/- 11.5, and 101.3 +/- 8.7 kcal/100 g, respectively. The average iron contents were 2.3 +/- 0.5, 2.3 +/- 0.5, 2.6 +/- 0.3, and 1.8 +/- 0.8 mg/ 100 kcal, respectively, and the average zinc contents were 1.6 +/- 0.1, 1.6 +/- 0.1, 1.7 +/- 0.1, and 1.6 +/- 0.2 mg/100 kcal. Developing a suitable complementary food from local ingredients and educating households in nutrition and use of local products are feasible. Such education should come with measures aimed at improving the accessibility of some ingredients to ensure feasibility and sustainability.

    Full Text Available Cet article s’intéresse à l’impact des réglementations sur les marchés de producteurs en Italie, ainsi qu’à l’approvisionnement local et les choix du consommateur. En regardant la vie quotidienne du marché, on réalise que les réglementations ne sont pas seulement imposées, mais aussi négociées et interprétées en fonction des besoins locaux. Des changements dans les attitudes concernant l’hygiène des aliments dévoilent un discours sur la modernité et met en valeur la lutte de la nouvelle Italie pour s’adapter à une société de plus en plus « consumériste »tout en cherchant à garder les traditions et l’ alimentation locale. Malgré la compétition des hypermarchés et les réglementations de plus en plus restrictives, les marchés de producteurs ont une clientèle très fidèle et la plus jeune génération a commencé à s’intéresser à l’alimentation produite localement. Ce nouveau groupe a en plus un grand désir de participer à la vie sociale du marché, aspect qui rend ces institutions publiques uniques.This article looks at the impact of regulations on farmers’ markets in Italy, local food supply and provisioning choices. By exploring the everyday running of the market, it becomes clear that regulations are not just imposed, but rather negotiated and interpreted to fit local needs. Changing attitudes towards food hygiene also uncover discourses of modernity and struggles to adapt to the new Italian ‘consumer society’ while holding onto tradition and local food. Despite competition from supermarkets and increasingly restrictive regulations, farmers’ markets in Italy have a faithful core group of clients and interest is slowly growing on the part of a young generation who want to eat locally and share in the social life of the market.

    Aiming to investigate the effect of diet and food consumption with regard to health, environment, and economy in light of nutrition ecology, we studied the dimensions of nutrition and food security in urban and rural settings in the region of Chapada dos Veadeiros, Central Brazil. We tracked diet and food consumption through carbon and nitrogen stable isotope ratios in fingernails of these inhabitants together with food intake data as a proxy for their diet patterns. We estimated household food insecurity by using the Brazilian Food Insecurity Scale. Nutrition and food insecurity was observed in both urban and rural areas, but was accentuated in rural settings. The diet pattern had high δ(13)C values in fingernails and low δ(15)N. Both urban and rural areas have diets with low diversity and relying on low-quality processed food staples at the same time that nutrition and food insecurity is quite high in the region.

    This study was initiated to examine if variations in the concentrations of cadmium (Cd) and lead (Pb) in water environment may affect metal levels in local foods and body burden of local residents in non-polluted areas in Japan. Two nationwide databases have been made available on concentrations of Cd in locally harvested brown rice and of Cd and Pb in sediments in local river beds. These data were combined with published data on metal concentrations in polished rice, food duplicates, and blood and urine from the residents. Cd in river sediments correlated significantly with those in brown rice, food duplicates, blood, and urine. Cd in food duplicates correlated with Cd in rice. In contrast, Pb concentrations in the river sediments either did not correlate or correlated only weakly with Pb in biological materials or food duplicates. Possible implication of the different behavior between Cd and Pb regarding the intensity of correlation was discussed with reference to the different routes of exposure to the elements. In conclusions, the Cd body burden on local residents in Japan is significantly influenced by Cd levels in water in the general environment, whereas water-borne Pb did not show clear correlation with the Pb body burden.

    Promotion of dietary diversity using locally available nutritious foods is an effective approach in low-income areas to improve the quality of young children's diet and, hence, their growth and development. To identify the nutritional values of locally acceptable, feasible, affordable, and sustainable foods and develop a number of recipes that could be used to complement effectively nutrient intakes provided through breastfeeding to children 6 to 23 months of age in Bandiagara, Mali. Structured questionnaires were used to obtain lists of all locally available foods during village assembly meetings and identify the food basket of households and child feeding practices during interviews with mothers and fathers. The nutritional values of the foods were estimated, and the Malian food composition table was used to identify the combinations that would result in the most nutritious recipes. Breastfeeding was widely practiced, but the rate of exclusive breastfeeding during the first 6 months of life was extremely low (7%). The practice of early introduction of water and complementary foods was a problem. Forty recipes for improved dishes, including puddings, drinks and juices, purees, salads, and soups, were proposed. The nutritional values of the 10 most nutritious of these recipes, the types and quantities of the ingredients, and the method of preparation of each recipe are described. Locally produced indigenous foods in rural Mali were used to develop energy- and nutrient-dense complementary foods for children. Further research is needed to test the short- and long-term effects of consuming these dishes on the nutritional status of children 6 to 23 months of age in Mali.

    San Francisco Bay (California, USA) and its local watersheds present an interesting case study in estuarine mercury (Hg) contamination. This review focuses on the most promising avenues for attempting to reduce methylmercury (MeHg) contamination in Bay Area aquatic food webs and identifying the scientific information that is most urgently needed to support these efforts. Concern for human exposure to MeHg in the region has led to advisories for consumption of sport fish. Striped bass from the Bay have the highest average Hg concentration measured for this species in USA estuaries, and this degree of contamination has been constant for the past 40 years. Similarly, largemouth bass in some Bay Area reservoirs have some of the highest Hg concentrations observed in the entire US. Bay Area wildlife, particularly birds, face potential impacts to reproduction based on Hg concentrations in the tissues of several Bay species. Source control of Hg is one of the primary possible approaches for reducing MeHg accumulation in Bay Area aquatic food webs. Recent findings (particularly Hg isotope measurements) indicate that the decades-long residence time of particle-associated Hg in the Bay is sufficient to allow significant conversion of even the insoluble forms of Hg into MeHg. Past inputs have been thoroughly mixed throughout this shallow and dynamic estuary. The large pool of Hg already present in the ecosystem dominates the fraction converted to MeHg and accumulating in the food web. Consequently, decreasing external Hg inputs can be expected to reduce MeHg in the food web, but it will likely take many decades to centuries before those reductions are achieved. Extensive efforts to reduce loads from the largest Hg mining source (the historic New Almaden mining district) are underway. Hg is spread widely across the urban landscape, but there are a number of key sources, source areas, and pathways that provide opportunities to capture larger quantities of Hg and reduce loads

    Three higher education institutions, University of Nebraska-Lincoln (UNL), Brooklyn College, and Lehman College, are working together to share expertise and resources to expand climate change topics offered to undergraduate and graduate students in New York City (NYC). This collaboration combines existing UNL educational learning resources and infrastructure in virtual coursework. It will supply global climate change education and locally-based research experiences to the highly diverse undergraduate students of Brooklyn and Lehman Colleges and to middle and high school teachers in NYC. Through the university partnership, UNL materials are being adapted and augmented to include authentic research experiences for undergraduates and teachers using NASA satellite data, geographic information system (GIS) tools, and/or locally collected microclimate data from urban gardens. Learners download NASA data, apply an Earth system approach, and employ GIS in the analysis of food production landscapes in a dynamically changing climate system. The resulting course will be offered via Blackboard courseware, supported by Web 2.0 technologies designed specifically to support dialogue, data, and web publication sharing between partners, teachers and middle school, high school and undergraduate student researchers. NYC is in the center of the urban farming movement. By exploring water and food topics of direct relevance to students' lives and community, we anticipate that students will be motivated and more empowered to make connections between climate change and potential impacts on the health and happiness of people in their community, in the United States and around the world.

    Full Text Available Consumers and institutional kitchens, as well as traders, have shown increasing interest towards local food. This is particularly due to the transparency and traceability characteristic of a short supply chain and social aspects related to food origins. The trend has been increasingly common during the past decade in Europe and North America, and it is strongly evident in the case area of this study in Northern Ostrobothnia, Finland. In general, ease of access to food is highly important for consumers and crucial for institutional kitchens, in addition to quality aspects and price. However, regardless of proximity, poor accessibility is one of the key issues preventing the further growth of local food markets. Due to scale economics in food value chain, food transport is presently organised mainly by centralised, large-scale logistics companies directed via hubs serving millions of consumers. Accordingly, production volumes required to enter large-scale markets are often unattainable for disjointed small-scale local food producers. In this study, geographic information system (GIS-based accessibility analyses are applied for analysing potential for integral networking of local food production and transport companies. Berry production was selected as a case study because it has a relatively strong role in Northern Ostrobothnia, while its logistics are notably underdeveloped. Spatial data of primary production volumes consists of register records of farm-specific cultivation areas and average yields in Northern Ostrobothnia and Finland. Accessibility computations are based on the digital model of the Finnish road network, Digiroad. Two surveys were also implemented to farmers and food processing companies to seek views on food processing, sales, logistics and procurements regarding local food. Data from the surveys was used in accessibility analysis, which enables exploration of opportunities for establishing ‘local food’ clusters integrating

  19. Geographies of Origin and Proximity: Approaches to Local Agro-Food Systems

    Full Text Available The present paper aims to provide a critical review with respect to the literature on Local Agro-Food Systems (LAFS in America and Europe over the last two decades, devoted to investigating the geographies of the relationships between territory and identity-based food products. In studies on LAFS, the concept of origin of food products is based upon a historical and bio-cultural analysis of food identity. Debates on territorial anchorage focus on the causal factors —natural, cultural and socio-economic— that a distinctive territory imprints on the specific attributes of identity-based foods. Moreover, the notion of geographical and organisational proximity aligns with a socio-cultural and economic approach to collective action aiming at rural development. A LAFS implies a certain spatial density and a network of mutually cooperating farms, firms and institutions, specialised in producing and marketing an identity-based food product, what can in turn be used to valorise the food identity both on the markets and also by contributing to the creation of common and public goods. A transdisciplinary view is required both for comprehending the emergence and evolution over centuries of the identity-based foods and also for understanding the role they play in constructing more sustainable rural development in the future.El artículo tiene como objetivo efectuar una revisión crítica de la literatura aparecida en las dos últimas décadas sobre los Sistemas Agroalimentarios Locales (SIAL en América y en Europa, que investiga la geografía de las relaciones existentes entre el territorio y los productos alimentarios identitarios. En los estudios sobre SIAL, el concepto de origen está basado en un análisis histórico y bio-cultural de la identidad de los alimentos. Los debates sobre el anclaje territorial se focalizan en los factores causales —naturales, culturales y socioeconómicos— que un territorio distintivo incide en los atributos espec

    Uranium and thorium and potassium are naturally occurring radioactive materials present in all soils, and therefore radioactivity can be found at every step of the food chain. Consumption of food contaminated with radioactive fallout may cause risk, radiation injuries from internal radiation. In the present work thirty five samples of different types of food materials were collected from the local markets, like: seeds, seasonings, fish, dried vegetables, rice, tea, coffee, milk, black honey... etc.. These were studied to determine the radioactive content, i.e. of uranium, thorium and potassium, and to determine the quantity of poisons and heavy metals in order to know the safety of eating such food. From the results, it was observed that the uranium concentration varied with a maximum value (20.74), for radium the maximum value was (20.08), for thorium the maximum value was (7.93), and for potassium the maximum value determined was (1179.54) Bq/kg. The radium equivalent (Ra eq ), the l γ index, the air absorbed rate due to Ra, and due to U, the external (H ex ) and internal (H int ) hazards and the AGDE were estimated. It is noted from the present results that it is safe to eat the above samples yet the accumulation of large amounts may produce high doses of radiation to people, especially that cesium was detected in some samples, and the maximum concentration was 4.39 Bq/kg. The atomic absorption technique was used to determine the concentration of some metals in twelve samples

    Full Text Available Features of the built environment provide opportunities to engage in both healthy and unhealthy behaviours. Access to a high number of fast food restaurants may encourage greater consumption of fast food products. The distribution of fast food restaurants at a state-level has not previously been reported in Australia. Using the location of 537 fast food restaurants from four major chains (McDonald׳s, KFC, Hungry Jacks, and Red Rooster, this study examined fast food restaurant locations across the state of Victoria relative to area-level disadvantage, urban–regional locality (classified as Major Cities, Inner Regional, or Outer Regional, and around schools. Findings revealed greater locational access to fast food restaurants in more socioeconomically disadvantaged areas (compared to areas with lower levels of disadvantage, nearby to secondary schools (compared to primary schools, and nearby to primary and secondary schools within the most disadvantaged areas of the major city region (compared to primary and secondary schools in areas with lower levels of disadvantage. Adjusted models showed no significant difference in location according to urban–regional locality. Knowledge of the distribution of fast food restaurants in Australia will assist local authorities to target potential policy mechanisms, such as planning regulations, where they are most needed.

    This project aimed to identify how local government planning tools could be used to influence physical and policy environments to support healthy eating behaviours in communities. An audit of Queensland's legislative and non-legislative local government planning tools was conducted by a public health nutritionist to assess their potential use in addressing strategies to achieve positive nutrition outcomes. Ten strategies were identified and covered the following themes: improving access to healthy foods and drinks; increasing access to breastfeeding facilities; decreasing fast food outlet density; and unhealthy food advertising. The audit found that all of the 10 strategies to achieve positive nutrition outcomes could be considered through three or more of the planning tools. Based on the findings of this audit, local government planning tools provide opportunities to address food and nutrition issues and contribute toward creating physical and policy environments that support healthy eating behaviours.

    Claudia Schillinger

    Full Text Available The polymicrobial nature of periodontal diseases is reflected by the diversity of phylotypes detected in subgingival plaque and the finding that consortia of suspected pathogens rather than single species are associated with disease development. A number of these microorganisms have been demonstrated in vitro to interact and enhance biofilm integration, survival or even pathogenic features. To examine the in vivo relevance of these proposed interactions, we extended the spatial arrangement analysis tool of the software daime (digital image analysis in microbial ecology. This modification enabled the quantitative analysis of microbial co-localization in images of subgingival biofilm species, where the biomass was confined to fractions of the whole-image area, a situation common for medical samples. Selected representatives of the disease-associated red and orange complexes that were previously suggested to interact with each other in vitro (Tannerella forsythia with Fusobacterium nucleatum and Porphyromonas gingivalis with Prevotella intermedia were chosen for analysis and labeled with specific fluorescent probes via fluorescence in situ hybridization. Pair cross-correlation analysis of in vivo grown biofilms revealed tight clustering of F. nucleatum/periodonticum and T. forsythia at short distances (up to 6 µm with a pronounced peak at 1.5 µm. While these results confirmed previous in vitro observations for F. nucleatum and T. forsythia, random spatial distribution was detected between P. gingivalis and P. intermedia in the in vivo samples. In conclusion, we successfully employed spatial arrangement analysis on the single cell level in clinically relevant medical samples and demonstrated the utility of this approach for the in vivo validation of in vitro observations by analyzing statistically relevant numbers of different patients. More importantly, the culture-independent nature of this approach enables similar quantitative analyses for "as

    Full Text Available The market of local and organic food is still a niche market in the USA, despite its strong growth rates. Both offer consumers an alternative to a globalized anonymous food supply chain. Yet local food and organic food seem to beoverlapping and to some degree competing food concepts. While the organic food market somehow has managed to “mature”, being widely distributed in national supermarket chains, local food in the US still seems to be tied to a“grassroots food movement”, being mainly distributed over short food supply chains. With several trends indicating sustained growth for local and organic consumption, this paper first addresses different connotations of local foodand compares them to standard definitions of organic food. The main focus is to explore the perception of US consumers towards local and organic food, using results from two different studies. Both studies use laddering techniques and word association tests, which were undertaken at Cornell University in New York State and at the University of Florida in the city of Gainesville. These findings are used to achieve a better understanding of the image of local and organic food, and the motives and values of local and organic food consumers.

    To examine the relationship between local food environments and obesity and assess the quality of studies reviewed. Systematic keyword searches identified studies from US and Canada that assessed the relationship of obesity to local food environments. We applied a quality metric based on design, exposure and outcome measurement, and analysis. We identified 71 studies representing 65 cohorts. Overall, study quality was low; 60 studies were cross-sectional. Associations between food outlet availability and obesity were predominantly null. Among non-null associations, we saw a trend toward inverse associations between supermarket availability and obesity (22 negative, 4 positive, 67 null) and direct associations between fast food and obesity (29 positive, 6 negative, 71 null) in adults. We saw direct associations between fast food availability and obesity in lower income children (12 positive, 7 null). Indices including multiple food outlets were most consistently associated with obesity in adults (18 expected, 1 not expected, 17 null). Limiting to higher quality studies did not affect results. Despite the large number of studies, we found limited evidence for associations between local food environments and obesity. The predominantly null associations should be interpreted cautiously due to the low quality of available studies. © 2015 The Obesity Society.

    Separate household food waste collection for anaerobic digestion is one method used in the sustainable management of biodegradable municipal solid waste (MSW). Recycling of food waste contributes to the UK's reuse, recycling and composting targets and can help local authorities boost plateauing rates whilst encouraging landfill diversion. This study explored the reasons for differences in the provision of food waste collections, using two comparable local authorities, one with a collection in Wales (Cardiff), and the other absent of such service in England (Southampton). A PESTLE analysis investigated the political, economic, social, technological, legal and environmental impacts of separate food waste collections. The greenhouse gas impacts of the collection and treatment systems of MSW in both cities were estimated for 2012/13. Results showed significant policy and legislative differences between devolved governments, that separate food waste collections can save local authorities significant sums of money and substantially reduce greenhouse gas impacts. A survey of one hundred respondents in each city aimed to understand attitudes and behaviours towards recycling, food waste segregation, cooking and purchasing habits. The number of frequent recyclers and levels of satisfaction were higher in the authority which provided a separate food waste collection. In the area which lacked a separate collection service, over three-quarters of respondents would participate in such a scheme if it were available. Copyright © 2017 Elsevier Ltd.

    During 2013, the New York City Department of Health and Mental Hygiene (DOHMH) received reports of 6 hepatitis A cases among food handlers. We describe our decision-making process for public notification, type of postexposure prophylaxis (PEP) offered, and lessons learned. For 3 cases, public notification was issued and DOHMH offered only hepatitis A vaccine as PEP. Subsequent outbreaks resulted from 1 case for which no public notification was issued or PEP offered, and 1 for which public notification was issued and PEP was offered too late. DOHMH continues to use environmental assessments to guide public notification decisions and offer only hepatitis A vaccine as PEP after public notification but recognizes the need to evaluate each situation individually. The PEP strategy employed by DOHMH should be considered because hepatitis A vaccine is immunogenic in all age groups, can be obtained by local jurisdictions more quickly, and is logistically easier to administer in mass clinics than immunoglobulin.

    One of health problems phenomenon in Indonesian and the world is increasing the degenerative disease because human’s bad habits of eating that having less fiber. Source of fiber which is relatively abundant in eastern Indonesia is seaweed that is very precise to fortified on local food that aims to be more nutritious and economically valuable. The purpose of this study is to got appropriate seaweed fortification technique to produce Seaweed Crispy Enbal (SCE) as typical food from Kei islands that rich in fiber and preferred by consumers. The research was done in two stages. The first stage is to analyze quality of fiber and HCN content of seaweed and enbal flour as SCE raw material, and the two-stage is fortified fiber to enbal lempeng using two types of raw materials, namely pulp seaweed and flour seaweed. The results showed that the fiber content of seaweed Eucheuma cottonii and flour enbal respectively 7.01% and 4%, while HCN content less than 3 mg/kg. Fortification techniques using pulp seaweed better than others. It is because pulp seaweed produces seaweed crispy enbal with high value of sensory (really like) with having fiber content is 7.48%.

    Full Text Available Any human activity needs to realize conditions purposeful to the economic objectives to be pursued and to do this, needs to modify the original environmental equilibrium. These situations are clearly observable in agricultural activities, whose development has often determined an “artificialisation” so intense to change the original appearance of entire areas. The evolution of the territorial role of agriculture has implicated the coexistence among various economic activities, some of which have gained benefits from the “artificialisation” realized by farmers. It is the case of touristic activities and food services which take advantages from the beauty and from the attractiveness of landscapes shaped by agricultural activities. The purpose of this paper is to verify how, for territorial realities where tourist offer found its main basis on contexts realized by agriculture, the set of economic activities can take advantages from the sustainable use of the same resource and, therefore, it can contribute to its development. To this aim, we’ll take as an example the recent development of food and wine tourism, in Italy, as an important expression of tangible socio-economic systems based on the enhancement of local resources.

    Full Text Available Abstract Background The local retail food environment around schools may act as a potential risk factor for adolescent diet. However, international research utilising cross-sectional designs to investigate associations between retail food outlet proximity to schools and diet provides equivocal support for an effect. In this study we employ longitudinal perspectives in order to answer the following two questions. First, how has the local retail food environment around secondary schools changed over time and second, is this change associated with change in diet of students at these schools? Methods The locations of retail food outlets and schools in 2001 and 2005 were geo-coded in three London boroughs. Network analysis in a Geographic Information System (GIS ascertained the number, minimum and median distances to food outlets within 400 m and 800 m of the school location. Outcome measures were ‘healthy’ and ‘unhealthy’ diet scores derived from adolescent self-reported data in the Research with East London Adolescents: Community Health Survey (RELACHS. Adjusted associations between distance from school to food retail outlets, counts of outlets near schools and diet scores were assessed using longitudinal (2001–2005 n=757 approaches. Results Between 2001 and 2005 the number of takeaways and grocers/convenience stores within 400 m of schools increased, with many more grocers reported within 800 m of schools in 2005 (p Conclusions The results provide some evidence that the local food environment around secondary schools may influence adolescent diet, though effects were small. Further research on adolescents’ food purchasing habits with larger samples in varied geographic regions is required to identify robust relationships between proximity and diet, as small numbers, because of confounding, may dilute effect food environment effects. Data on individual foods purchased in all shop formats may clarify the frequent, overly simple

    Full Text Available The article attempts to provide a theoretical discussion on territorial governance by presenting both the neo-institutionalist position and the De Sousa Santos’ alternative models, with a view of highlighting the dimensions that can be relevant to understanding the territorial dynamics of Local Agro-food Systems (LAFS. The paper aims to build up a system of indicators, structured in four dimensions, concerning the territorial governance of LAFS: (i multi-level coordination; (ii democratic participation and accountability; (iii cooperation among producers and other stakeholders and (iv relationships with the environment. We verify, as a hypothesis, that the typology of markets to which the identity-based products are directed plays a decisive role in the way that processes of territorial governance of LAFS are constructed. The results of an empirical research, developed in four LAFS in Mexico, are presented: prickly pear cactus in Morelos, blackberry in Michoacán, cuitlacoche (corn smut in Tlaxcala and coffee in Veracruz. Two types of territorial governance of LAFS may be distinguished: those that can be strengthened by the geographical and organisational proximity of the markets and the action of local stakeholders and governments—prickly pear cactus and cuitlacoche—versus those which are devoted to export and are conducted by large companies in which marketing networks involve certification mechanisms and a large number of institutions—coffee and blackberry.

    The objective of the present study was to explore the influence of participation in community-supported agriculture (CSA) on vegetable exposure, vegetable intake during and after the CSA season, and preference related to locally produced vegetables acquired directly from CSA growers. Quantitative surveys were administered at three time points in two harvest seasons to four groups of CSA participants: new full-paying, returning full-paying, new subsidized and returning subsidized members. Questionnaires included a vegetable frequency measure and measures of new and changed vegetable preference. Comparisons were made between new and returning CSA members and between those receiving subsidies and full-paying members. The research was conducted in a rural county in New York, USA. CSA members who agreed to participate in the study. Analysis was based on 151 usable questionnaires. CSA participants reported higher intake of eleven different vegetables during the CSA season, with a sustained increase in some winter vegetables. Over half of the respondents reported trying at least one, and up to eleven, new vegetables. Sustained preferences for CSA items were reported. While those who choose to join a CSA may be more likely to acquire new and expanded vegetable preferences than those who do not, the CSA experience has the potential to enhance vegetable exposure, augment vegetable preference and increase overall vegetable consumption. Dietary patterns encouraged through CSA participation can promote preferences and consumer demand that support local production and seasonal availability. Emphasis on fresh and fresh stored locally produced vegetables is consistent with sustainable community-based food systems.

    Full text: Background: Despite much progress, the prevalence of stunting and acute malnutrition remains too high in Vietnam. Since 2010, the National Institute of Nutrition, UNICEF-Vietnam and the Institut de Recherche pour le Développement have been working on the development of locally produced ready-to-use foods (RUFs) for severe and moderate acute malnutrition (SAM/MAM). In contrast to clear evidence of the effectiveness of RUFs for SAM in Africa, data are limited with respect to the acceptability and effectiveness of RUFs in South-East Asia. A report from Cambodia showed poor acceptability of peanut-based RUFs. The present study examined the acceptability of a locally produced supplementary RUF in Vietnamese preschool children and their caregivers. Methods: The local produced RUSF was formulated in accordance to the recent WHO guidelines on specifications for RUSF. The study was conducted in two kindergartens in Bac Giang province, Vietnam. Preschool children (n = 61) aged 3-5 years and having WHZ between -3 and -1.0 z-score (mean -1.53 Z-score) and/or a MUAC less than 125 mm, were included in the study. Selected children were given daily one sachet of local RUSF (92g) as snack meal rations for 5 days/week for two consecutive weeks. Weight and height was measured at baseline and endline. In addition, eaten quantity, eating patterns and hedonic evaluation of children and their caregivers were collected. Results: Most children (75.4%) consumed >75% of the offered RUSF with 85.8% (95% CI: 80.5, 91.1) of the offered RUSF consumed. Sex and age of children affected the amount of RUSF eaten. Almost all children and their caregivers scored the product high on organoleptic properties. Children gained on average 2 g/kg body weight per day over the study period. The majority of caregivers reported a willingness to buy the RUSF for their children. Conclusion: The locally produced RUSF had a positive impact on weight gain, and was very well-accepted by Vietnamese

    Full Text Available The emergence of Food Tourism worldwide has encouraged the rise of numerous food tourism strategies and initiatives everywhere, including Colombia. These are flourishing thanks to the tourism and cultural policies that recognise Colombian food processes and practices as intangible cultural heritage. One of the most representative strategies nowadays is the case of Medellín Sí Sabe (Medellín has a taste. The programme has been led by the local authorities and has been backed by different local organisations. This paper outlines an exploratory approach based on literature review, public documents, policies and the information obtained through nine semi-structured interviews applied to key stakeholders responsible for the implementation of this initiative in Medellín. The information provides some insights into how this strategy has had relevant effects on the local economic revitalisation by linking small and medium-sized food enterprises, which base their activity mainly on traditional dishes and products of the region. Firstly, it analyses the strategy’s structure and its link to national tourism and cultural policies based on the main concepts of territorial development: knowledge, learning and innovation. By analysing Medellín (Colombia as case study, it recognises the role played by local authorities in the promotion of food tourism.

    Full Text Available Local food has recently gained popularity under the assumption that it is more sustainable than food from distant locations. However, evidence is still lacking to fully support this assumption. The goal of this study is to compare local and global food chains in five dimensions of sustainability (environmental, economic, social, ethical and health, covering all stages of the chain. In particular, four cheese supply chains are compared in detail: a local (L’Etivaz and global (Le Gruyère case in Switzerland and a local (Single Gloucester and global (Cheddar case in the UK. A multi-dimensional perspective is adopted to compare their sustainability performance. Eight attributes of performance (affordability, creation and distribution of added value, information and communication, consumer behaviour, resource use, biodiversity, nutrition and animal welfare are used to frame the comparative analysis. The results suggest that local cheese performs better in the field of added value creation and distribution, animal welfare and biodiversity. Global chains, by contrast, perform better in terms of affordability and efficiency and some environmental indicators. This analysis needed to be expressed in qualitative terms rather than quantified indicators and it has been especially useful to identify the critical issues and trade-offs that hinder sustainability at different scales. Cheese supply chains in Switzerland and the UK also often present hybrid arrangements in term of local and global scales. Comparison is therefore most meaningful when presented on a local (farmhouse/global (creamery continuum.

There is currently no national community-based program run by government to take care of these children, one of the reasons being lack of access to ready-to-use therapeutic food (RUTF). To develop RUTF using locally available food ingredients and test its acceptability. A checklist was prepared for all food ingredients available and commonly consumed in Bangladesh that have the potential of being used for developing a RUTF. Linear programming was used to identify the combinations of nutrients that would result in an ideal RUTF. To test the acceptability of 2 local RUTFs compared to the prototype RUTF, Plumpy'Nut, a clinical trial with a crossover design was conducted among 30 children in the Dhaka Hospital of International Centre for Diarrhoeal Disease Research, Bangladesh. The acceptability was determined by using the mean proportion of offered food consumed by the children themselves. Two RUTFs were developed, one based on chickpea and the other on rice-lentils. The total energy content of 100 g of chickpea and rice-lentil-based RUTF were 537.4 and 534.5 kcal, protein 12.9 and 13.5 g, and fat 31.8 and 31.1 g, respectively, without any significant difference among the group. On an average, 85.7% of the offered RUTF amount was consumed by the children in 3 different RUTF groups which implies that all types of RUTF were well accepted by the children. Ready-to-use therapeutic foods were developed using locally available food ingredients-rice, lentil, and chickpeas. Chickpea-based and rice-lentil-based RUTF were well accepted by children with SAM.

    Caregiver and child behaviours during feeding have been used to measure responsiveness, which has been recognised as important for child growth and development. The aims of this study were to understand how caregiver and child behaviours differ when feeding lipid-based nutrient supplements (LNS) vs. local complementary food and to detect associations between behaviours and child interest in food. Sixteen moderately underweight 6-17-month-old Malawian children receiving 50 g/day of supplementary LNS for 12 weeks were videotaped during LNS (n = 32) and local complementary feeding (n = 28) episodes. Behaviours were coded at the level of the intended bite (1674 total bites). The analysis used regression models adjusted for within-subject correlation. Caregivers were less likely to allow children to self-feed and more likely to use physical pressure during LNS vs. complementary food bites. Positive caregiver verbalization was infrequent and did not differ by type of food. Higher odds of accepting a bite were associated with the bite containing LNS, odds ratio (OR) 3.05; 90% confidence interval (CI) (1.98, 4.71), the child self-feeding, OR 5.70; 90% CI (2.77, 11.69), and positive caregiver verbalization, OR 2.46; 90% CI (1.26, 4.80), while lower odds of acceptance were associated with negative child verbalization during feeding, OR 0.27; 90% CI (0.17, 0.42). In this sample, caregivers used more responsive feeding practices during bites of local complementary food and were more controlling when feeding LNS. Responsive caregiver behaviours predicted child acceptance of food. These results could be used to design interventions in Malawi to improve responsive feeding practices in general and during LNS use. © 2011 John Wiley & Sons Ltd.

    Full text: Background and objectives: Inadequate energy and micronutrient intake during childhood is a major public health problem in many developing countries including Bangladesh, particularly in food insecure communities. Locally produced ready-to-use supplementary food (RUSF) can improve growth, development and micronutrient status of children. The study was conducted to develop recipes for RUSF based on locally available food ingredients and to test their acceptability among children. Methods: A checklist was prepared of available and commonly consumed food ingredients that have the potential of being used for RUSF. Linear programming was used to determine possible combinations of ingredients and required micronutrient premix composition, and samples were prepared in the icddr,b food-processing lab. To test the acceptability of the RUSF recipes compared to Pushti-packet (a cereal based food-supplement), an acceptability trial was conducted among 90 children aged 6-18 months in a slum in Mirpur, Dhaka, Bangladesh. The mothers were asked to rate the color, flavor, mouth-feel, and overall liking of the RUSF by using a 7-point hedonic scale (1 = dislike extremely, 2 = dislike moderately, 3 = dislike, 4 = neither dislike nor like, 5 = like slightly, 6 = like moderately, 7 = like extremely). Results: Two RUSFs were developed, one based on rice and lentils and the other one on chickpea. Mean response for each sensory quality of all products was more than 6. The two RUSFs scored significantly better compared to Pushti-packet in terms of ‘overall liking’. Children were offered 50g of food and they consumed (mean+SD) 26.1±15.1g RUSF and 17.1±14.3g Pushti-packet which took them 20.9±9.6 minutes. There was no significant difference between two RUSF consumption, but there was a significant difference between chickpea-based RUSF and Pushti-packet (28.4 vs.17.1g) consumption. Conclusions: Locally available food ingredients were used to develop RUSFs for preventing and

    The current study examined parental perceptions of sociocultural factors associated with healthy child feeding practices among parents of preschool-age children in rural Japan. Fifteen Japanese mothers of preschool-age children participated in this qualitative study. These participants were aged 22-39 years and resided in a rural town in western Japan. We conducted semi-structured qualitative interviews to assess parental perceptions of healthy child feeding practices and their relationships with globalization and localization. These interviews were transcribed, translated into English and coded, based on the principles of grounded theory. A codebook was developed and pre-identified, and the newly-identified themes from this codebook were examined and compared. Overall, local and seasonal foods, along with traditional Japanese foods and simple foods (soshoku), were considered to be beneficial for children. Participants also noted that children were expected to be mindful and exhibit good table manners that reflect cultural values related to meal-time socializing or family bonding, and food appreciation. On the other hand, the majority of the participants stated that foods containing food additives and imported foods were unsuitable for children. Participants noted that strong social capital, especially social support from their mothers or mothers-in-law, as well as social networks for obtaining fresh local foods, contributed to healthy child feeding practices. Cultural capital (including the preservation of traditional Japanese dietary habits, eating rules and inter-generational commensality), was also identified as being key to healthy feeding practices. Identifying and promoting the social and cultural capital that positively support healthy child feeding practices may be an important component of nutrition education programs.

    Examine whether individual-level childhood obesity is related to residential availability of fast food and healthy food outlets. Retrospective cross-sectional study. Perth, Western Australia. A total of 1850 children aged 5 to 15 years in 2005-2010 who participated in the Western Australian Health and Wellbeing Surveillance System survey. Geographical Information Systems were used to calculate a range of measures of fast food and healthy food outlet access and availability. For example, distance to nearest and access and density measures within 800 m and 3 km of each child's residence were all tested. Multivariate logistic regression analysis, controlling for individual-level sociodemographic factors and lifestyle behaviors. An increasing number of healthy food outlets within 800 m of a child's home was associated with a significantly reduced risk of being overweight/obese in all models tested. After controlling for age, physical activity, time spent sedentary, weekly takeaway consumption, area disadvantage, and count of fast food outlets, each additional healthy food outlet within 800 m was associated with a 20% decrease in the likelihood of a child being overweight or obese (odds ratio: .800, 95% confidence intervals: .686-.933). The local food environment around children's homes has an independent effect on child weight status. These findings highlight the importance of the built environment as a potential contributor towards child health, which should be considered when developing community health promotion programs.

    Research on the local knowledge of food plants used by Karo ethnic in the Semangat Gunung Village, North Sumatra has been done. The aim of this study is to reveal plant species that used by the people of Karo ethnic as food. We used the ethnobotanical approach which included open-ended, semi-structural interview, and exploration method. One eldervillage, 2 traditional healers, and 30 respondents have been selected as sources of information. Descriptive statistics have been used to analyze the gathered data. A number of 109 species which belong to 83 genus and 45 families known to be used as food sources by Karo people. Four families have the highest number of food plant species, which are Solanaceae (8 species), Poaceae (7 species), Fabaceae (6 species), and Zingiberaceae (6 species). All of those families are found in the village, both wild and Cultivated. Solanaceae is used as source of fruits, vegetables, and spices. Poaceae is used as the source of the staple food, alternative food sources, snacks, spices, and traditional foods. Fabaceae is used as source of vegetables and traditional foods. Zingiberaceae is used as source of spices.

    There is concern that extraneous factors, such as food and drink, may alter the pharmacodynamics of Mectizan(®) (ivermectin) in patients receiving this important anti-parasitic drug, and thus might put such individuals in danger of serious adverse events. The effects of a common local alcohol-containing beverage and a local food on plasma levels of ivermectin were studied in Sudanese volunteers after administration of the standard dose used in mass drug administration programs for onchocerciasis and filariasis. Plasma levels of ivermectin at various time points (0-48h) after administration of ivermectin were ascertained by HPLC assay in ten volunteers given 150μgkg(-1) ivermectin together with either a local sorghum-based food ('assida'), or a locally brewed alcoholic beverage ('arangi' made from sorghum grain) or in those who were fasting. Maximum mean (±SD) plasma levels of ivermectin (67±49ngml(-1)) were reached within 2h in fasting patients, and had dropped to 26±20ngml(-1) after 30h. The coadministration of local food or alcoholic beverage did not cause an increase in ivermectin plasma levels above those observed in people who were fasting. However, at 2h after ivermectin administration, patients given alcohol had significantly lower plasma ivermectin levels than fed patients or fasting patients. There were no significant differences among treatments for AUC0-30, Cmax, or tmax, and so the coadministration of local food or alcoholic beverage did not cause any change in pharmacokinetic parameters of ivermectin in the plasma in comparison with fasting. None of the measured levels of plasma ivermectin were greater than those reported in previous studies with this compound. These findings do not support the hypothesis that acute intake of alcohol is an important factor in the development of the serious adverse reactions that can occur during the treatment of loaisis patients with ivermectin (Mectizan(®)).

    Traditional use of local wild and cultivated plants for making recreational tea in Estonia often borders with the medicinal use of the same plants. The aim of this paper is to map the perceptions of plants used for making tea and to define the domains of recreational and medicinal teas in specific cultural settings. Between November 2011 and March 2012 the authors distributed electronic questionnaires on the use of wild food plants in childhood. The questionnaire was answered by 250 respondents. 178 of them reported the use of plants for making recreational teas. The responses were analysed according to the taxonomy of the used plants, the most frequently used taxa and families were detected, the influence of respondents' demographic data on the number of use reports was assessed and the overlapping of medicinal and recreational uses was discussed. The study detected 69 vascular plant species, ten vascular taxa identified on the genera level only, and one lichen. The most popular families were Rosaceae, Asteraceae and Lamiacea, and 12 taxa were used by at least 10% of the respondents, while only one of them (Tilia) was used by more than 50% and one (Rubus idaeus) by over 33% of the respondents. The next ten most used taxa were: Rosa, Mentha, Primula veris, Matricaria, Achillea millefolium, Hypericum, Carum carvi, Urtica dioica, Thymus serpyllum and Fragaria. Of the 30 most used consolidated taxa mentioned in five or more use records, only four were used exclusively in one domain. The majority of the used plants were situated on the recreational-medicinal continuum, which could be divided into two domains: recreational, medicinal and the "grey" area that lies around the borderline. The predominance of the cold and cold-related diseases on the spectrum treated by plants used for making recreational tea reflects the climatic conditions of the region and suggests that they are the most commonly self-treated diseases in the region, seen from the child's perspective.

    Peanut is succeptable to aflatoxin contamination and the sources of peanut as well as processing methods considerably affect aflatoxin content of the products. Therefore, the study on aflatoxin and nutrient contents of peanut collected from local market and their processed foods were performed. Good kernels of peanut were prepared into fried peanut, pressed-fried peanut, peanut sauce, peanut press cake, fermented peanut press cake (tempe) and fried tempe, while blended kernels (good and poor kernels) were processed into peanut sauce and tempe and poor kernels were only processed into tempe. The results showed that good and blended kernels which had high number of sound/intact kernels (82,46% and 62,09%), contained 9.8-9.9 ppb of aflatoxin B1, while slightly higher level was seen in poor kernels (12.1 ppb). However, the moisture, ash, protein, and fat contents of the kernels were similar as well as the products. Peanut tempe and fried tempe showed the highest increase in protein content, while decreased fat contents were seen in all products. The increase in aflatoxin B1 of peanut tempe prepared from poor kernels > blended kernels > good kernels. However, it averagely decreased by 61.2% after deep-fried. Excluding peanut tempe and fried tempe, aflatoxin B1 levels in all products derived from good kernels were below the permitted level (15 ppb). This suggests that sorting peanut kernels as ingredients and followed by heat processing would decrease the aflatoxin content in the products.

    Neighborhood characteristics, such as healthy food availability, have been associated with consumption of healthy food. Little is known about the influence of the local food environment on other dietary choices, such as the decision to consume organic food. We analyzed the associations between organic produce consumption and demographic, socioeconomic and neighborhood characteristics in 4,064 participants aged 53-94 in the Multi-Ethnic Study of Atherosclerosis using log-binomial regression models. Participants were classified as consuming organic produce if they reported eating organic fruits and vegetables either "sometimes" or "often or always". Women were 21% more likely to consume organic produce than men (confidence interval [CI]: 1.12-1.30), and the likelihood of organic produce consumption was 13% less with each additional 10 years of age (CI: 0.84-0.91). Participants with higher education were significantly more likely to consume organic produce (prevalence ratios [PR] were 1.05 with a high school education, 1.39 with a bachelor's degree and 1.68 with a graduate degree, with less than high school as the reference group [1.00]). Per capita household income was marginally associated with produce consumption (p = 0.06), with the highest income category more likely to consume organic produce. After adjustment for these individual factors, organic produce consumption was significantly associated with self-reported assessment of neighborhood produce availability (PR: 1.07, CI: 1.02-1.11), with an aggregated measure of community perception of the local food environment (PR: 1.08, CI: 1.00-1.17), and, to a lesser degree, with supermarket density (PR: 1.02: CI: 0.99-1.05). This research suggests that both individual-level characteristics and qualities of the local food environment are associated with having a diet that includes organic food.

    Like several Southeast Asian countries, Singapore has a complex eating-out environment and a rising eating-out prevalence. However the determinants and drivers of eating-out in urban Asian environments are poorly understood. We examined the socio-demographic characteristics of persons who frequently ate away from home in local eateries called hawker centres and Western fast-food restaurants, using data from 1647 Singaporean adults participating in the National Nutrition Survey (NNS) 2010. We also assessed the underlying drivers of eating out and evaluated if these were different for eating at local eateries compared to Western fast-food restaurants using 18 focus group discussions of women (130 women). Participants reported a high eating-out frequency with 77.3% usually eating either breakfast, lunch or dinner at eateries. Main venues for eating-out included hawker centres (61.1% usually ate at least 1 of 3 daily meals at this venue) and school/workplace canteens (20.4%). A minority of participants (1.9%) reported usually eating at Western fast-food restaurants. Younger participants and those of Chinese and Malay ethnicity compared to Indians were more likely to eat at Western fast-food restaurants. Chinese and employed persons were more likely to eat at hawker centres. The ready availability of a large variety of affordable and appealing foods appeared to be a primary driver of eating out, particularly at hawker centres. Our findings highlight the growing importance of eating-out in an urban Asian population where local eating venues play a more dominant role compared with Western fast-food chains. Interventions focusing on improving the food quality at venues for eating out are important to improve the diet of urban Asian populations.

  18. Food Insecurity and Healthcare Costs: Research Strategies Using Local, State, and National Data Sources for Older Adults12

    Food insecurity in older adults is a clinically relevant problem with important implications for healthcare costs; however, few studies have examined the relationship between food insecurity and the healthcare cost burden in older adults. It may be due in part to lack of appropriate data and methods to examine these issues in the existing datasets. It is critical to identify and obtain the data necessary for estimating healthcare costs associated with food insecurity and to explore specific mechanisms by which food insecurity is related to adverse health outcomes and associated healthcare costs. This paper discusses how to best utilize and link available, nationally representative datasets and develop infrastructure and procedures to establish state and local datasets. As an example, an innovative approach tested in Georgia to establish a state-level dataset in a sample of low-income, older adults in need of food assistance is discussed. In this approach, data from the state aging services client database and the Centers for Medicare and Medicaid Services data were linked. Such efforts are essential to estimate the healthcare cost burden of food-insecure older adults who have a particularly higher burden of chronic diseases and direct future research, program, and policy decisions to improve the food and healthcare security of low-income, older adults.

    2015-01-01

    Environmental, public health, alternative food, and food justice advocates are working together to achieve incremental agricultural subsidy and nutrition assistance reforms that increase access to fresh fruits and vegetables. When it comes to targeting food and beverage products for increased regulation and decreased consumption, however, the priorities of various food reform movements diverge. This article argues that foundational legal issues, including preemption of state and local authority to protect the public's health and welfare, increasing First Amendment protection for commercial speech, and eroding judicial deference to legislative policy judgments, present a more promising avenue for collaboration across movements than discrete food reform priorities around issues like sugary drinks, genetic modification, or organics. Using the Vermont Genetically Modified Organism (GMO) Labeling Act litigation, the Kauai GMO Cultivation Ordinance litigation, the New York City Sugary Drinks Portion Rule litigation, and the Cleveland Trans Fat Ban litigation as case studies, I discuss the foundational legal challenges faced by diverse food reformers, even when their discrete reform priorities diverge. I also 'explore the broader implications of cooperation among groups that respond differently to the "irrationalities" (from the public health perspective) or "values" (from the environmental and alternative food perspective) that permeate public risk perception for democratic governance in the face of scientific uncertainty.

    Due to the persistent pollution of soils by an organochlorine, chlordecone (CLD also known as Kepone © ) in the French West Indies, some crops may be contaminated beyond the European regulatory threshold, the maximum residue limit (MRL). Farmers need to be able to foresee the risk of not complying with the regulatory threshold in each field and for each crop, if not, farmers whose fields are contaminated would have to stop cultivating certain crops in the fields concerned. To help farmers make the right choices, we studied the relationship between contamination of the soil and contamination of crops. We showed that contamination of a crop by CLD depended on the crop concerned, the soil CLD content and the type of soil. We grouped crop products in three categories: (i) non-uptakers and low-uptakers, (ii) medium-uptakers, and (iii) high-uptakers, according to their level of contamination and the resulting risk of exceeding MRL. Using a simulation model, we computed the soil threshold required to ensure the risk of not complying with MRL was sufficiently low for each crop product and soil type. Threshold values ranged from 0.02 μgkg -1 for dasheen grown in nitisol to 1.7 μgkg -1 for yam grown in andosol in the high-uptake category, and from 1 μgkg -1 for lettuce grown in nitisol to 45 μgkg -1 for the leaves of spring onions grown in andosol in the medium-uptake category. Contamination of non-uptakers and low-uptakers did not depend on soil contamination. With these results, we built an easy-to-use decision support tool based on two soil thresholds (0.1 and 1 μgkg -1 ) to enable growers to adapt their cropping system and hence to be able to continue farming.

  1. Peptidoglycan Hydrolases of Local Lactic Acid Bacteria from Kazakh Traditional Food

    Directory of Open Access Journals (Sweden)

    Serik Shaikhin

    2014-01-01

    Full Text Available Introduction: Peptidoglycan (PG is a major component of the cell wall of Gram-positive bacteria and is essential for maintaining the integrity of the bacterial cell and its shape. The bacteria synthesize PG hydrolases, which are capable of cleaving the covalent bonds of PG. They also play an important role in modeling PG, which is required for bacterial growth and division. In an era of increasing antibiotic-resistant pathogens, PG hydrolases that destroy these important structures of the cell wall act as a potential source of new antimicrobials. The aim of this study is to identify the main PG hydrolases of local lactic acid bacteria isolated from traditional foods that enhance probiotic activity of a biological preparation. Methods. Lactococcus lactis 17А and Lactococcus garvieae 19А were isolated from the traditional sausage-like meat product called kazy. They were isolated according to standards methods of microbiology. Genetic identification of the isolates were tested by determining the nucleotide sequences of 16S rDNA. The Republican collection of microorganisms took strains of Lactobacillus casei subsp. Rhamnosus 13-P, L. delbrueckii subsp. lactis CG-1 B-RKM 0044 from cheese, Lactobacillus casei subsp. casei B-RKM 0202 from homemade butter. They used the standard technique of renaturating polyacrylamide gel electrophoresis to detect PG hydrolases activity. Results. According to the profiles of PG hydrolase activity on zymograms, the enzymes of Lactococci 17A and 19A in kazy are similar in electrophoretic mobility to major autolysin AcmA, while the lactobacilli of industrial and home-made dairy products have enzymes similar to extracellular proteins p40 and p75, which have probiotic activity. Conclusions. Use of peptidoglycan hydrolases seems to be an interesting approach in the fight against multi-drug resistant strains of bacteria and could be a valuable tool for the treatment of diseases caused by these microorganisms in Kazakhstan.

Cross-sectional study design that drew upon neighbourhood- and individual-level data. For each participant, community (density and proximity) and community food environment (availability, variety, quality and price) measures of FV and SSB were assessed in retail food stores and specialized fresh produce markets within 1·6 km of their homes. Poisson generalized estimating equations (GEE) were used to model the associations of food consumption with food environment measures, adjusted by individual-level characteristics. São Paulo, Brazil. Adults (n 1842) residing in the same census tracts (n 52) in São Paulo, Brazil as those where the neighbourhood-level measures were taken. FV availability in neighbourhoods was associated with regular FV consumption (≥5 times/week; prevalence ratio=1·41; 95 % CI 1·19, 1·67). Regular FV consumption prevalence was significantly lower among lower-income individuals living in neighbourhoods with fewer supermarkets and fresh produce markets (P-interaction food environment is associated with FV and SSB consumption in a Brazilian urban sample.

    This study assessed the impact of changes in school food policy on student lunch consumption in middle schools. Two years of lunch food records were collected from students at three middle schools in the Houston, Texas area. During the first year, no changes occurred in the school food environment. After that school year was completed, chips and dessert foods were removed from the snack bars of all schools by the Food Service Director. Students recorded the amount and source of food and beverage items consumed. Point-of-service purchase machines provided a day-by-day electronic data file with food and beverage purchases from the snack bars during the 2-year period. Independent t-tests and time series analyses were used to document the impact of the policy change on consumption and sales data between the two years. In general, student consumption of sweetened beverages declined and milk, calcium, vitamin A, saturated fat and sodium increased after the policy change. Snack chips consumption from the snack bar declined in year 2; however, consumption of snack chips and candy from vending increased and the number of vending machines in study schools doubled during the study period. Ice cream sales increased significantly in year 2. Policy changes on foods sold in schools can result in changes in student consumption from the targeted environments. However, if all environments do not make similar changes, compensation may occur.

    2016-03-01

    Full Text Available Abstract Aims: The synthetic colors are preferred by the food industry because of the variety of shades, intensity, uniformity, excellent solubility and stability. They are used in a variety of food products such as dairy products, beverages, baked products, confections and pet foods. Food colors may have toxic effects on the human body. This study aimed to examine the amount of synthetic colors in some ready to use foods in Kashan, Iran. Instrument & Methods: In this cross sectional study, conducted in Kashan City, Iran, in March to October 2015, a total of 52 samples of meat products, 33 samples of sweets, 43 samples of drinks and 21 samples of miscellaneous foods were collected. The coloring agents were extracted of samples and purified using the hydrochloric acid extraction method. Thin layer chromatography was used to analyze the samples. Findings: 72 samples (48.30% contained no coloring and 77 samples (51.7% contained artificial colors. The most coloring agents were in sweets (72.7%, drinks (51.2% and meat products samples (48.10%. The quinoline yellow, tartrazine and sunset yellow were the most common coloring used in the various foods. Conclusion: About 52% of examined foods contained artificial colors that have been banned by the national Iranian standards organization.

    There is need for employing strategies to minimize measurement errors while administering semi-quantitative FFQ. The current study was planned to adapt and standardize locally available portion sizes for semi-quantitative FFQ to improve its validity and document the process of standardization of portion sizes. The study was conducted in 9 villages of the INCLEN-SOMAARTH DDESS (Demographic, Development and Environmental Surveillance Site), Palwal district, Haryana, India. The subjects in these nine villages are part of a cohort study to assess the interaction between societal and household factors with food intake and physical activity of children. Systematic utensil survey was undertaken in 3 randomly chosen households per village i.e. 27 households and the portion sizes were derived from a total of 74 serving utensils. The derived sizes were classified as small (240 ml), medium (320 ml) and large (600 ml). The semi-quantitative FFQ with locally derived portion sizes was then administered to 63 children in 6-12 year age group. The volume of food measured by the reference portion sizes generally being employed in the national surveys, would have been underestimated the food consumed by the child by 55-60% as compared to what was being consumed by the children in the study area. The correlation between food intake assessed by 24-hr recall method and FFQ using derived (local) portion sizes was better as compared to that obtained with the semi-quantitative FFQ done with reference portions. In conclusion, local portion size adaptation of FFQ for semi-quantification is useful to mitigate measurement errors associated with this technique.

    Laboratory accreditation provides a level of standardization in laboratories and confidence in generated food and feed testing results. For some laboratories, ISO/IEC 17025:2005 accreditation may not be fiscally viable, or a requested test method may be out of the scope of the laboratory's accreditation. To assist laboratories for whom accreditation is not feasible, the Association of Public Health Laboratories Data Acceptance Work Group developed a white paper entitled "Best Practices for Submission of Actionable Food and Feed Testing Data Generated in State and Local Laboratories." The basic elements of a quality management system, along with other best practices that state and local food and feed testing laboratories should follow, are included in the white paper. It also covers program-specific requirements that may need to be addressed. Communication with programs and end data users is regarded as essential for establishing the reliability and accuracy of laboratory data. Following these suggested best practices can facilitate the acceptance of laboratory data, which can result in swift regulatory action and the quick removal of contaminated product from the food supply, improving public health nationally.

    Local food environments can influence the diet and health of individuals through food availability, proximity to retail stores, pricing, and promotion. This study focused on how small convenience stores, known in New York City as bodegas, influence resident shopping behavior and the food environment. Using a cross-sectional design, 171 bodegas and 2118 shoppers were sampled. Small convenience stores in New York City. Any bodega shopper aged 18+ who purchased food or beverage from a participating store. Data collection consisted of a store assessment, a health and behavior survey given to exiting customers, and a bag check that recorded product information for all customer purchases. Descriptive statistics were generated for bodega store characteristics, shopper demographics, and purchase behavior. Multilevel models were used to assess the influence of product availability, placement, and advertising on consumer purchases of sugar-sweetened beverages (SSBs), water, and fruits and vegetables. Seventy-one percent of participants reported shopping at bodegas five or more times per week, and 35% reported purchasing all or most of their monthly food allotment at bodegas. Model results indicated that lower amounts of available fresh produce were significantly and independently associated with a higher likelihood of SSB purchases. A second, stratified multilevel model showed that the likelihood of purchasing an SSB increased with decreasing varieties of produce when produce was located at the front of the store. No significant effects were found for water placement and beverage advertising. Small convenience stores in New York City are an easily accessible source of foods and beverages. Bodegas may be suitable for interventions designed to improve food choice and diet.

  17. From famine to food crisis: what history can teach us about local and global subsistence crises.

    2011-01-01

    The number of famine prone regions in the world has been shrinking for centuries. It is currently mainly limited to sub-Saharan Africa. Yet the impact of endemic hunger has not declined and the early twenty-first century seems to be faced with a new threat: global subsistence crises. In this essay I question the concepts of famine and food crisis from different analytical angles: historical and contemporary famine research, food regime theory, and peasant studies. I will argue that only a more integrated historical framework of analysis can surpass dualistic interpretations grounded in Eurocentric modernization paradigms. This article successively debates historical and contemporary famine research, the contemporary food regime and the new global food crisis, the lessons from Europe's 'grand escape' from hunger, and the peasantry and 'depeasantization' as central analytical concepts. Dualistic histories of food and famine have been dominating developmentalist stories for too long. This essay shows how a blending of historical and contemporary famine research, food regime theory and new peasant studies can foster a more integrated perspective.

    The first thousand days of a child's life are critical for ensuring adequate nutrition to enable optimal health, development and growth. Inadequate infant and young child feeding (IYCF) practices likely contribute to Ethiopia's concerning malnutrition situation. Development partners in four regions of Ethiopia implemented community production of complementary food with women's groups processing local grains and legumes at grain banks to improve availability, accessibility, dietary diversity and timely introduction of complementary foods. The objective of this study was to establish the acceptability, perceived impact, feasibility and required inputs to sustain local grain bank interventions to improve IYCF. A subsidized barter system was used by mothers in the rural communities, and flour was sold in the semi-urban context. Purposive sampling guided the qualitative study design and selection of project stakeholders. A total of 51 key informant interviews and 33 focus group discussions (n = 237) were conducted. The grain bank flour was valued for its perceived diverse local ingredients; while the project was perceived as creating labour savings for women. The grain bank flour offered the potential to contribute to improved IYCF; however, further dietary modification or fortification is needed to improve the micronutrient content. Dependence upon external inputs to subsidize the barter model and the reliance on volunteer labour from women's groups in the rural context are the greatest risks to sustainability. This intervention illustrates how integrated agricultural and health interventions leveraging local production can appeal to diverse stakeholders as an acceptable approach to improve IYCF. © 2015 John Wiley & Sons Ltd.

    Full Text Available Abstract Background Individual-level health outcomes are shaped by environmental risk conditions. Norms figure prominently in socio-behavioural theories yet spatial variations in health-related norms have rarely been investigated as environmental risk conditions. This study assessed: 1 the contributions of local descriptive norms for overweight/obesity and dietary behaviour to 10-year change in glycosylated haemoglobin (HbA1c, accounting for food resource availability; and 2 whether associations between local descriptive norms and HbA1c were moderated by food resource availability. Methods HbA1c, representing cardiometabolic risk, was measured three times over 10 years for a population-based biomedical cohort of adults in Adelaide, South Australia. Residential environmental exposures were defined using 1600 m participant-centred road-network buffers. Local descriptive norms for overweight/obesity and insufficient fruit intake (proportion of residents with BMI ≥ 25 kg/m2 [n = 1890] or fruit intake of <2 serves/day [n = 1945], respectively were aggregated from responses to a separate geocoded population survey. Fast-food and healthful food resource availability (counts were extracted from a retail database. Separate sets of multilevel models included different predictors, one local descriptive norm and either fast-food or healthful food resource availability, with area-level education and individual-level covariates (age, sex, employment status, education, marital status, and smoking status. Interactions between local descriptive norms and food resource availability were tested. Results HbA1c concentration rose over time. Local descriptive norms for overweight/obesity and insufficient fruit intake predicted greater rates of increase in HbA1c. Neither fast-food nor healthful food resource availability were associated with change in HbA1c. Greater healthful food resource availability reduced the rate of increase in HbA1c

  3. Impact of lengthening open water season on food security in Alaska coastal communities: Global impacts may outweigh local "frontline" effects

    Science.gov (United States)

    Rolph, R.; Mahoney, A. R.

    2015-12-01

    Using ice concentration data from the Alaska Sea Ice Atlas from 1953-2013 for selected communities in Alaska, we find a consistent trend toward later freeze up and earlier breakup, leading a lengthened open water period. Such changes are often considered to bring a variety of "frontline" local impacts to Arctic coastal communities such as increased rates of coastal erosion. However, direct consequences of these changes to local food security (e.g. through impacts on subsistence activities and marine transport of goods) may be outweighed at least in the short term by the effects of large scale Arctic sea ice change coupled with global oil markets. For example, a later freeze-up might delay local hunters' transition from boats to snow-machines, but whether this trend will affect hunting success, especially in the next few years, is uncertain. Likewise, the magnitude of change in open water season length is unlikely to be sufficient to increase the frequency with which communities are served by barges. However, an expanding open water season throughout the Arctic has implications for the global economy, which can have indirect effects on local communities. In the Chukchi and Beaufort Seas, where rapid sea ice change has been accompanied by increased interest in oil and gas development, the U.S. Bureau of Ocean Energy Management currently requires drilling operations to cease 38 days prior to freeze up. Taking this into account, the lengthening open water season has effectively extended the drilling season for oil companies by 184% since the 1950s. If oil development goes ahead, local communities will likely experience a range of indirect impacts on food security due to increased vessel traffic and demand on infrastructure coupled with changes in local economies and employment opportunities. Increased likelihood of an oil spill in coastal waters also poses a significant threat to local food security. Thus, while Arctic coastal communities are already experiencing

  4. Nitrogen fixation associated with development and localization of mixed populations of Cellulomonas species and Azospirillium brasilense grown on cellulose or wheat straw

    1986-04-01

    Mixed cultures of Cellulomonas sp. and Azospirillum brasilense were grown with straw or cellulose as the carbon source under conditions favoring the fixation of atmospheric nitrogen. Rapid increases in cell numbers, up to 10/sup 9/ cells per g of substrate, were evident after 4 and 5 days of incubation at 30 degrees C for cellulose and straw, respectively. Nitrogen fixation (detected by acetylene reduction measured on parallel cultures) commenced after 2 and 4 days of incubation for straw and cellulose, respectively, and continued for the duration of the experiment. Pure cultures of Cellulomonas sp. showed an increase in cell numbers, but CO/sub 2/ production was low, and acetylene reduction was not detected on either cellulose or straw. Pure cultures of A. brasilense on cellulose showed an inital increase in cell numbers (10/sup 7/ cells per g of substrate) over 4 days, followed by a decline presumably caused by the exhaustion of available carbon substrate. On straw, A. brasilense increased to 10/sup 9/ cells per g of substrate over 5 days and then declined slowly; this growth was accompanied by acetylene reduction. Scanning electron micrographs of straw incubated with a mixture under the above conditions for 8 days showed cells of both species in close proximity to each other. Evidence was furnished that the close spatial relatioship of cells from the two species facilitated the mutally beneficial association between them and thus increased the efficiency with which the products of straw breakdown were used for nitrogen fixation. 17 references.

    Full Text Available Fifty samples from five baby food products mainly made of cereal flour(s were analyzed. The moisture contents of these products were between 11.14% and 11.9%, a level below 14.0%, the recommended level for safe storage of cereal grains and their products. The mycological analysis was carried out using the dilution plate method and two isolation media (DG18 for isolation of xerophilic fungi and DRBC for fungi in general. A total of 80 species related to 37 genera in addition to some unidentified fungal and yeast species were recorded on both media from the five products. The products were contaminated abundantly by xerophilic fungi which were occurring in 88% of food samples and accounting for 18.1% of the total CFU as recorded on DG18. The highest contamination level by xerophiles was registered in Mwebaza rice porridge (a component of rice flour and the lowest in Mukuza (a product of maize, soyabean and sorghum flours. 11 xerophilic species were recorded of which Aspergillus and Eurotium (4 species each were the predominant giving rise to 9.1% and 8.9% of the total CFU, with A. wentii, A. candidus, E. cristatum and E. repens were the most contaminating species. Of the fungi recorded other than xerophiles, species of Aspergillus (particularly A. flavus followed by A. niger, Penicillium (P. citrinum, P. oxalicum, Fusarium (F. solani, F. tricinctum, Cladosporium (C. sphaerospermum and yeasts were the most predominant. Contamination of such foods is a matter of health hazard as these foods are for babies. So, the use of fresh, well-dried and uncontaminated flours for production of such foods is recommended.

    The aim of this study was to compare the amount of radiocaesium in chosen parts of food chains from localities in the Eastern Slovakia. Prevailing part of radiocaesium is in the upper layer of soils and specific activity of 137 Cs in the first layer for locality Stara Voda in 2000 achieved 152.4 Bq/kg 1 . On the base of results from modified Tessier sequential extraction method we determined that more than 50 % of this radionuclide is in the soil in not extractable fraction. From studied species of mushrooms the highest value was determined in sample of Rozites caperata the and specific activity achieved 1822.0 Bq/kg 1 d. w. The aim of our study was to determine the amount of caesium in chosen parts of food chains from localities in Eastern Slovakia for period 2000-2004. On the base of obtained results we can conclude that radiocaesium migrates vertically in soils very slowly and prevailing part of caesium is in the upper layer. Prevailing part of radiocaesium is in the not extractable fraction. Extremely low concentration of caesium in soil solution is the factor limiting caesium uptake by the root systems, too. Mushrooms are characterised by high ability to accumulate radiocaesium. (authors)

The results show that there is a large difference in transport regularities of radioactive silicate particles and radioactive solutions in GIT. At intake of young fission products high concentrations of radionuclides in GIT content deal with sorption and concentrating of radionuclides on food particles and observe in third stomach, blind gut, terminals of middle and bung guts. Transport regularities of fused radioactive particles depend on digestive apparatus mobility, content consistency and morphological peculiarities of mucosa, which work towards transport slowing and storage of such particles in the part of sheep GIT with minimal dry substance content - abomasum [ru

    To explore and compare the characteristics of Primary Education Centres (PEC) in Andalusia, the Canary Islands and the Principality of Asturias depending on whether or not they make local food purchases (LFP) for school meals and to explore the opinion of cafeteria managers about the benefits and challenges of this type of purchase. Information on the characteristics of 186 PECs and opinions of cafeteria managers about the benefits/challenges of LFP was collected through an electronic questionnaire. Data were stratified according to how the products were purchased (LFP: yes/no), and the chi square test was applied. 38.2% of the PECs studied make LFP. This is more frequent in rural areas (51.0 with self-managed cafeterias (80.0%), and their own kitchen (65.5%). These centres have less expensive menus than their peers (69.8%), participate more frequently in healthy eating programmes (81.5%) and purchase more organic food products (65.8%). According to the majority of the participants whose centres engage in LFP, the benefits include: supporting the local economy (97.2%), the offer of fresh foods (97.2%) and environmental sustainability (93.0%). The challenges include: productive capacity of the region (50.7%), the seasonal variation in food production (71.8%), and the lack of support (42.3%) and information from the government (46.5%). The location of the centres, the management of the cafeteria and the availability of a kitchen on site can influence the development of LFP in schools. Government support could help to integrate LFP in schools, improving school meals at a lower economic and environmental cost. Copyright © 2017 SESPAS. Publicado por Elsevier España, S.L.U.

    Full Text Available The process of socio-educational territorialisation in rural contexts is the topic of this text. The theme corresponds to a challenge to address it having as main axis of discussion either the problem of social exclusion or that of local development. The reasons to locate the discussion in this last field of analysis are discussed in the first part of the text. Theoretical and political reasons are there articulated because the question is about projects whose intentions and practices call for the political both in the theoretical debate and in the choices that anticipate intervention. From research conducted for several years, I use contributions that aim at discuss and enlighten how school can be a potential locus of local development. Its identification and recognition as local institution (either because of those that work and live in it or because of those that act in the surrounding context are crucial steps to progressively constitute school as a partner for development. The promotion of the local values and roots, the reconstruction of socio-personal and local identities, the production of sociabilities and the equation and solution of shared problems were the dimensions of a socio-educative intervention, markedly globalising. This scenario, as it is argued, was also, intentionally, one of transformation and of deliberate change of school and of the administration of the educative territoires.

Les données présentées sont issues d’une enquête qualitative portant sur les processus de valorisation dans le département de la Drôme. Nous présenterons la construction des normes internes au système d’action de valorisation repéré sur ce territoire à travers trois de ses fondements : l’adhésion à des normes de production, l’adhésion à des normes de distribution ainsi qu’à une inscription dans la vie culturelle locale. À travers ces trois aspects, nous verrons se profiler la logique de valorisation caractérisant ce système. Cette logique de valorisation transmet des valeurs spécifiques aux productions et participe ainsi à les légitimer. La mise en relief de cette forme de légitimité est l’objectif de la réflexion proposée.The aim of this article is to highlight the way in which local food products are given legitimacy, presenting qualitative data from a survey of product enhancement activities in the department of the Drôme. It describes the internal standards defined by three tenets underlying those activities: adherence to production standards; adherence to standards of distribution; and adherence to local cultural life. Our aim is to outline the rationale behind the system - a rationale that in conferring particular values to particular products also helps to give them legitimacy.

    2016-12-01

    Climate change is predicted to have negative impacts on agriculture and food security in many parts of sub-Saharan Africa. Regional and temporal climate variability will disburse these effects, creating opportunities to mitigate food shortages through well-studied international, regional, and national food flows and associated food prices. However, most food products consumed and traded by rural smallhold farmers rely on local market exchanges that take place outside the scope of prevalent regional and national market analysis. There is little empirical evidence on these rural markets outside of their potential for smallholder agribusiness. However, they offer an unopened window into local food supply and the nuances of food movements in rural areas. Our research explores how to analyze the cost and availability of food products in rural markets and their connection with each other, as well as with nearby households' food security. This new approach of using food markets as a unit of analysis necessitates a new framework that groups markets based on a hierarchy of variables relevant to their role as food movers and suppliers. In our research, we collected price and source data for 22 commodities bought and sold within 52 rural markets in 12 districts spatially distributed throughout Zambia. We continue to collect data via phone interviews with 206 traders and market managers within these markets each month. We used this data to develop a typology of stationary rural food markets based on their size in terms of traders and buyers, the diversity of commodities available year-round and seasonally, their price transmission with other markets, and their trading scheme and governance. The result is a dynamic framework with varying weights on each variable that classifies which characteristic of markets under which conditions increase their potential for local food shortage resilience and mitigation. We also allocate for commodity-specific scenarios to allow for modeling

    Italy, with a cultivated area of 218,000 ha, is a European leader of rice production. In particular Lombardy region accounts for 40% of total rice cultivation and the case study in object accounts for 3.2% of Lombardy total rice area (2773 ha). Starting from 2012, through a regional project titled Buono, Sano e Vicino (good, healthy and close), Riso e Rane rural district supported local rice farmers in developing innovation in rice production and promoting an alternative supply chain to increase farmers bargaining power and promote new market strategies. More specifically, the innovation introduced is a new biotech method for variety certification, named DNA controllato (DNA tested). In the first step of the project, the attention was focused on an Italian traditional variety of rice: Carnaroli rice. Thanks to a commercial agreement with one of the most important large retailers in Lombardy, the Riso e Rane rice is offered for sale both in the traditional and wholegrain version. In this context, this work aims to evaluate the determinants of consumer's quality perception of this product, through a preference study of the commercial rice package. Preliminary results reveal that consumers perceive information about origin, local food-system and tradition more easily than DNA tested certification. In conclusion, this work contributes to evaluate the role of bio economy applications to the food sector and offers new insights for the debate about the relationships between tradition and innovation.

    2017-11-01

    Full Text Available Research on food planning has been recently proposed in North American and European planning to account for how cities might change their food provision to respond to the rising demands for a more sustainable and ethical food system. The purpose of this paper was to evaluate the agro-ecological potential of the Lisbon city region, Ribatejo e Oeste, to increase its Regional Food Self-Reliance (RFSR, through adopting demand restraint and food system relocalization approaches to food system sustainability. Three new diet scenarios were considered: meat-based, plant-based and strict vegetarian, defined in accordance with healthy dietary patterns. We used agro-climatic and agro-edaphic agricultural suitability models to evaluate the agro-ecological potential for RFSR, and proposed the use of Foodshed Landscape Plans within a landscape planning methodology. Results showed the extent of local food production that could improve food self-reliance, with 72%, 76%, 84% of total food needs in the meat-based, plant-based, and strict vegetarian scenarios, respectively. Thus, food system transformation by means of relocalization, is therefore ecologically feasible and would ensure the sustainable use of the ecological basis of food security. Additionally, a dietary transition would imply significant land sparing, which strengthens the demand restraint perspective for a transition to food system sustainability.

    Full Text Available Its huge area of cultivated lands (about 5 million hectares makes Serbia stand out against other states of the Balkan region. Food products are still one of the most important components of Serbian export. From 1 March 2012, when Serbia was granted the candidate status to the European Union, making ready to effectively competite with the Member States of the EU, which offer very similar products, became a chance of survival for Serbia’s agricultural and –food industry sector . A chance to increase the absorbency of the internal market creates an increasing culinary awareness in the Serbian society; despite the economic crisis, the Serbians are looking for new, previously unknown tastes or new taglines for tastes already known in Serbian cuisine. The real challenge for Serbian agriculture is the promotion of culinary tourism, which involves exhibiting the ability to compete with other Balkan countries by depicting a more diverse range of attractions. Promotion of the regional products is done by events typical for culinary tourism – festivals, culinary competitions, culinary tourist routes, as well as reconstructions of medieval cuisine. In the realities of Serbia, culinary tourism opens the opportunities for sustainable development of the periphery areas and, at the same time, makes it possible to retain old customs and traditions.

    The present study was undertaken to determine bacterial load as well as characterize bacterial flora of ready to eat (RTE) betel leaf sold at local markets in Mymensingh city. A total of 25 RTE betel leaf samples were collected from five local markets such as Kamal-Ranjit (KR) market, Shesh more, Kewatkhali, Jobber more, and Ganginar par. Total viable count of bacteria in betel leaf (log 10 mean colony forming unit±standard deviation/ml) was 7.58±0.04 for KR market, 7.72±0.06 for Shesh more, 7.62±0.04 for Kewatkhali, 7.40±0.03 for Jobber more, and 7.60±0.06 for Ganginar par. A total of 98 bacterial isolates belong to five genera ( Escherichia coli , Salmonella spp., Vibrio spp., Bacillus spp., and Staphylococcus spp.) were identified. The prevalence of E. coli was 17.34%, Salmonella spp. was 25.51%, Vibrio spp. was 19.39%, Bacillus spp. was 18.37%, and Staphylococcus spp. was 19.39%. Antibiotic sensitivity test showed that all isolates were sensitive to two antibiotics such as ciprofloxacin and gentamicin. Four isolates ( E. coli , Salmonella spp., Vibrio spp., and Staphylococcus spp.) were resistant to two antibiotics (ampicillin and cephalexin). Antibiogram profile of bacterial isolates of betel leaf suggests that they were multidrug resistance. Data of this study indicate that betel leaf sold at local market harbors multidrug resistance food-borne bacteria which might cause public health hazards if these antibiotic resistant transfer to human through food chain.

    The stimulating effects of low doses of ionizing radiation on growth of various plants has been reported by many investigators. In 1970, the FAO/IAEA consultant group strongly recommended tomato as a test plant due to its economic importance and good adaptability to many climatic conditions. This work was carried out during the summer seasons of 1990 and 1992 in two sites in Damascus region. Samples of air dried seeds of tomato (Local variety) of previous season were irradiated by gamma-rays from a 137 Cs source using doses of 5, 10, 12.5, 15, 20, 30 and 40 Gy at dose rate of 9 Gy/min. Seeds were sown after 2 days from irradiation in complete randomized block design and replicated 4 times. The data revealed that gamma irradiation at interval doses of 5-12.5 Gy (in Khan-El-Sheeh) and 10-30 Gy (in Deir-El-Hajar) have stimulating effects on number of branches and early yield. The results of total yield as well as fruits number were significantly increased when doses of 10 and 12.5 Gy in Khan-El-Sheeh and 12.5-25 Gy in Deir-El-Hajar, were used. The percentage of increment varied from 12.6 to 18.2% in Khan-El-Sheeh and 14.3 to 30.9% in Deir-El-Hajar. In view of all above mentioned results, the use of radiation might be recommended as an easy tool for seed treatments to stimulate and increase the productivity of tomato. (author). 12 tabs

    Despite the ability of the globalised food system to deliver varied and plentiful food supplies to most in the developed world it also disconnects consumers from where, how and by whom food is grown, which discourages food citizenship. This paper uses an ecological framework to examine the individual, social, physical and macro-level environments that can positively or negatively influence peoples' engagement with food citizenship. This research used narrative inquiry methodology and purposive sampling to gather stories through focus group conversations. Fifty-two people voluntarily attended focus groups comprised of food procurers from one of five sources: community gardens, Community Supported Agriculture (CSA), farmers' markets, fresh food markets or supermarkets. A narrative was constructed for each of these groups of food procurers; their commonalities and particularities were illuminated through a final interpretive narrative. The findings showed that the community gardeners exhibited a range of personal characteristics that prioritised engagement with local food systems. The physical setting of the community garden enabled the gardeners to make connections to the earth and the people within their social networks. The CSA and farmers' market groups were cognisant of the implications of their food choices and usually proved to be food citizens, as they selected seasonal, local and ethically produced food from their farmer(s). The fresh food market shoppers were ambivalent towards organic and seasonal food and the market setting did not connect them directly to the provenance of their food. The supermarket shoppers' disconnection from those who grew their food and where it was grown disempowered them from making sustainable food choices. Adjustments to the macro-level food environment are needed to enable people to have a greater commitment to food citizenship. Copyright © 2016 Elsevier Ltd. All rights reserved.

    This study was conducted to determine the occurrence and levels of total aflatoxins in complementary foods (CFs) and their ingredients. A total of 126 samples collected from 20 Districts from Amhara, Tigray, Oromia, and Southern Nations Nationalities and Peoples (SNNP) regions were analysed for levels of total aflatoxins using enzyme linked immunosorbent assay (ELISA). Aflatoxins were detected in 62 out of 66 pre-milling samples with mean range of 0.3-9.9 µg/kg. Aflatoxins were also detected in 19 out of 20 post-production CFs and in all of the one-month stored CFs at households and grain banks, with a mean range of 0.5-8.0, 3.6-11.3, and 0.2-12.4 µg/kg, respectively. Overall, 3 out of 126 samples exceeded the maximum limit (10 µg/kg). Although most aflatoxin levels were below the maximum limit and thus considered to be safe for consumption, more effort should be implemented to reduce contamination, as these CFs are intended for consumption by young children.

    The present investigation was carried out to study the effectiveness of some antimicrobial food additives on the microbial status and organoleptic quality of local cheese stored at 25 0 C for six weeks. Aspergillus flavus, Penicillium citrinum and Aspergillus niger were the predominant genera isolated from cheese samples. Treatment with propionic acid (600 and 1000 ppm), potassium sorbate (2000 and 3000 ppm) and sodium chloride (4 and 8%) decrease significantly the total fungal count of cheese less than 106/g over 4 weeks of storage at 25 0 C. Gamma irradiation with 3 kGy completely inhibited the growth of mycelia and no mycotoxins were detected. Treatment cheese with propionic acid (1000 ppm), potassium sorbate (3000 ppm) and sodium chloride (8%) developed no detectable spoilage odour during 3 weeks of storage at 25 0 C whereas untreated cheese was spoiled between one to two weeks. The results of the present study revealed that the use of the antimicrobial food preservatives play a great role on the inhibition of microorganisms contaminating stored cheese without cussing any organoleptic quality

    Saudi Arabia produces a majority of its fruits and vegetables locally in small-scale production farms. These farms utilize groundwater as the main source of irrigation water. The water-regulating authorities in Saudi Arabia rely on traditional culturing methods to monitor coliforms as indicators of microbial contamination. These methods are time-consuming, do not address the sources of contamination, and do not permit assessment on the associated health risk. To address these knowledge gaps, the study investigates the sources of contamination in eight wells northeast of Mecca, Saudi Arabia. The study focuses on the potential impact on groundwater quality due to a nearby chicken farm and urban runoffs from human residential areas. Besides performing conventional methods to determine nutrient content and to enumerate coliforms, quantitative PCR using four host-associated primer sets were used to distinguish microbial contamination from humans and livestock. High-throughput sequencing was also performed to determine the relative abundance of several genera associated with opportunistic pathogens. Bacterial isolates were cultivated from the vegetable samples harvested from these farms, and were characterized for their phylogenetic identities. Lastly, the study collates the information to perform quantitative microbial risk assessment due to ingesting antibiotic-resistant Listeria monocytogenes, Pseudomonas aeruginosa and Enterococcus faecalis in these vegetable samples.

    2016-06-01

    Full Text Available During the 1980’s collective action was initiated with the purpose of saving the remnants of traditional livestock farming in Jämtland. This led to the articulation of a local agro-food system (LAFS that managed to commercialize important elements of traditional agriculture by adding elements of modernity. Farm diversification was an important strategy that led to the forward integration of farms that includes the start of small scale farm dairies, farm cafes, direct sales, at the farm, through markets and other local channels, B&Bs and outdoor tourism operations. In the mentioned process, foreign knowledge and experience led to the opening of a new market for traditional products. This case shows that the localization and appropriation of foreign elements can be a fruitful strategy to promote territorial development in regions like Jämtland. This article highlights how a LAFS was articulated within the frame of the birth of a new industry, composed by small, semi-artisan dairy firms and which institutional side effects that this experience has led to.Durante la década de los 80, un proceso de acción colectiva se inició con el propósito de salvar los restos de la ganadería tradicional en Jämtland. Esto resultó en la creación de un sistema agroalimentario local que logró comercializar elementos importantes de la agricultura tradicional, añadiendo elementos de modernidad. La diversificación de las fincas fue la estrategia más importante, dentro de la cual se promovió la creación de un sector de pequeñas industrias lácteas en las fincas, cafés rurales y asimismo la venta directa a los consumidores en dichas fincas, en mercados y otros canales de comercialización, servicios de alojamiento y desayuno y operaciones turísticas al aire libre. En este proceso, conocimiento y experiencias extranjeras jugaron un papel clave en la apertura de un nuevo mercado para los productos lácteos tradicionales. Este caso demuestra que la

    Women of reproductive age are at nutritional risk due to their need for nutrient-dense diets. Risk is further elevated in resource-poor environments. In one such environment, we evaluated feasibility of meeting micronutrient needs of women of reproductive age using local foods alone or using local foods and supplements, while minimizing cost. Based on dietary recall data from Ouagadougou, we used linear programming to identify the lowest cost options for meeting 10 micronutrient intake recommendations, while also meeting energy needs and following an acceptable macronutrient intake pattern. We modeled scenarios with maximum intake per food item constrained at the 75th percentile of reported intake and also with more liberal maxima based on recommended portions per day, with and without the addition of supplements. Some scenarios allowed only commonly consumed foods (reported on at least 10% of recall days). We modeled separately for pregnant, lactating, and nonpregnant, nonlactating women. With maxima constrained to the 75th percentile, all micronutrient needs could be met with local foods but only when several nutrient-dense but rarely consumed items were included in daily diets. When only commonly consumed foods were allowed, micronutrient needs could not be met without supplements. When larger amounts of common animal-source foods were allowed, all needs could be met for nonpregnant, nonlactating women but not for pregnant or lactating women, without supplements. We conclude that locally available foods could meet micronutrient needs but that to achieve this, strategies would be needed to increase consistent availability in markets, consistent economic access, and demand. © 2017 John Wiley & Sons Ltd.

    Aim and method: CO 2 -gas-exchange and transpiration of open-grown Norway spruce (about 12 m high) on the top of the Black Forest (1230 m a.s.l.) near Freiburg under local conditions with and without ozone are being continiously measured through the whole year. In the same intensity are registered the temperature of soil, needles, twigs, stem and air, the humidity in soil and air and the diameter-changes of the stem. Nearby other institutions measure the quality of air and depositions. Results: In winter with less snowfall, higher temperature and higher insolation, the youngest twigs of the spruce had a lower net-photosynthesis but a higher respiration at night on the southern part versus nothern part (with more shade). Perhaps it happened an inactivity of the photosynthesis-apparatus because of too high insolation. In the same time the colour of the needles on the southern part changed to yellowish green (on the northern part they remained dark green). During dry summer periods the photosynthesis dropped earlier and deeper. The 'radial-increment' stagnated. There was no difference in the gas-exchange when the ozone concentration had been enlarged, neither in winter nor in summertime. (orig.). 57 figs., 12 tabs., 178 refs [de

    Previous reports have been estimated that more than 90% of serum PCDD/Fs can be accounted for by the consumption of various food groups. Nouwen et al. suggested residents living near incinerators with the elevated dioxin exposure while they ate locally produced food compared to the general population from other areas. PCDD/Fs usually abound in fatty meats and marine foods, and consumption of which is the major pathway of human expose to PCDD/Fs. However, no distinct association was shown between vegetarian regime of human and their corresponding serum PCDD/Fs concentration. In addition, the resident region is associated to their corresponding dietary consumption and ambient exposure of PCDD/Fs, especially for subjects consumed the local foods with special dioxin-like contamination. The current study, therefore, was set to examine how dietary habits, including vegetarian regime and consumption of local food original for residents living near the incinerators are associated to serum PCDD/F concentrations. In addition, the further aim is to assess the influence on the serum PCDD/Fs levels resulting from subjects living in the alternative resident regions, even all of them exposed to PCDD/Fs emission from incinerators.

    Full Text Available Food legumes comprise all legumes grown for human food in China as either dry grains or vegetables, except for soybean and groundnut. China has a vast territory with complex ecological conditions. Rotation, intercropping, and mixed cropping involving pulses are normal cropping systems in China. Whether indigenous or introduced crops, pulses have played an important role in Chinese cropping systems and made an important contribution to food resources for humans since ancient times. The six major food legume species (pea, faba bean, common bean, mung bean, adzuki bean, and cowpea are the most well-known pulses in China, as well as those with more local distributions; runner bean, lima bean, chickpea, lentil, grass pea, lupine, rice bean, black gram, hyacinth bean, pigeon pea, velvet bean, winged bean, guar bean, sword bean, and jack bean. China has remained the world's leading producer of peas, faba beans, mung beans, and adzuki beans in recent decades, as documented by FAO statistics and China Agriculture Statistical Reports. The demand for food legumes as a healthy food will markedly increase with the improvement of living standards in China. Since China officially joined the World Trade Organization (WTO in 2001, imports of pea from Canada and Australia have rapidly increased, resulting in reduced prices for dry pea and other food legumes. With reduced profits for food legume crops, their sowing area and total production has decreased within China. At the same time, the rising consumer demand for vegetable food legumes as a healthy food has led to attractive market prices and sharp production increases in China. Vegetable food legumes have reduced growing duration and enable flexibility in cropping systems. In the future, production of dry food legumes will range from stable to slowly decreasing, while production of vegetable food legumes will continue to increase.

    Toxic elements emitted from the Pechenganickel complex on the Kola Peninsula have caused concern about potential effects on local wild food in the border regions between Norway, Finland and Russia. The aim of this study was to assess Ni, Cu, Co, As, Pb, Cd, and Hg concentrations in local wild foods from these border regions. During 2013-2014, we collected samples of different berry, mushroom, fish, and game species from sites at varying distances from the Ni-Cu smelter in all three border regions. Our results indicate that the Ni-Cu smelter is the main source of Ni, Co, and As in local wild foods, whereas the sources of Pb and Cd are more complex. We observed no consistent trends for Cu, one of the main toxic elements emitted by the Ni-Cu smelter; nor did we find any trend for Hg in wild food. Concentrations of all investigated toxic elements were highest in mushrooms, except for Hg, which was highest in fish. EU maximum levels of Pb, Cd, and Hg were exceeded in some samples, but most had levels considered safe for human consumption. No international thresholds exist for the other elements under study.

    Full Text Available Abstract Background The Food Frequency Questionnaire (FFQ is one of the most commonly used tools in epidemiologic studies to assess long-term nutritional exposure. The purpose of this study is to describe the development of a culture specific FFQ for Arab populations in the United Arab Emirates (UAE and Kuwait. Methods We interviewed samples of Arab populations over 18 years old in UAE and Kuwait assessing their dietary intakes using 24-hour dietary recall. Based on the most commonly reported foods and portion sizes, we constructed a food list with the units of measurement. The food list was converted to a Semi-Quantitative Food Frequency Questionnaire (SFFQ format following the basic pattern of SFFQ using usual reported portions. The long SFFQ was field-tested, shortened and developed into the final SFFQ. To estimate nutrients from mixed dishes we collected recipes of those mixed dishes that were commonly eaten, and estimated their nutritional content by using nutrient values of the ingredients that took into account method of preparation from the US Department of Agriculture's Food Composition Database. Results The SFFQs consist of 153 and 152 items for UAE and Kuwait, respectively. The participants reported average intakes over the past year. On average the participants reported eating 3.4 servings/d of fruits and 3.1 servings/d of vegetables in UAE versus 2.8 servings/d of fruits and 3.2 servings/d of vegetables in Kuwait. Participants reported eating cereals 4.8 times/d in UAE and 5.3 times/d in Kuwait. The mean intake of dairy products was 2.2/d in UAE and 3.4 among Kuwaiti. Conclusion We have developed SFFQs to measure diet in UAE and Kuwait that will serve the needs of public health researchers and clinicians and are currently validating those instruments.

  1. What role do local grocery stores play in urban food environments? A case study of Hartford-Connecticut.

    Directory of Open Access Journals (Sweden)

    Katie S Martin

    Full Text Available INTRODUCTION: Research on urban food environments emphasizes limited access to healthy food, with fewer large supermarkets and higher food prices. Many residents of Hartford, Connecticut, which is often considered a food desert, buy most of their food from small and medium-sized grocery stores. We examined the food environment in greater Hartford, comparing stores in Hartford to those in the surrounding suburbs, and by store size (small, medium, and large. METHODS: We surveyed all small (over 1,000 ft2, medium, and large-sized supermarkets within a 2-mile radius of Hartford (36 total stores. We measured the distance to stores, availability, price and quality of a market basket of 25 items, and rated each store on internal and external appearance. Geographic Information System (GIS was used for mapping distance to the stores and variation of food availability, quality, and appearance. RESULTS: Contrary to common literature, no significant differences were found in food availability and price between Hartford and suburban stores. However, produce quality, internal, and external store appearance were significantly lower in Hartford compared to suburban stores (all p<0.05. Medium-sized stores had significantly lower prices than small or large supermarkets (p<0.05. Large stores had better scores for internal (p<0.05, external, and produce quality (p<0.01. Most Hartford residents live within 0.5 to 1 mile distance to a grocery store. DISCUSSION: Classifying urban areas with few large supermarkets as 'food deserts' may overlook the availability of healthy foods and low prices that exist within small and medium-sized groceries common in inner cities. Improving produce quality and store appearance can potentially impact the food purchasing decisions of low-income residents in Hartford.

    Full Text Available The Slow Food Movement and the Gastronomic Tourism are developing experiments in the gastronomy in different dimensions. Actually, the activities performed by each of these actors are complementary and can help to enhance, one hand, the production and preservation of local culture and, on the other hand, offer a touristic attraction and quality that matches the expectations of gastronomic tourists. Thus, this study aims to observe gastronomic itineraries planned by the Slow Food movement in the city of Recife, Brazil, in conjunction with a travel agency, giving priority to analyse the repercussions of that partnership. The data collection was done through questionnaires and these data were submited to content analysis.The results show that the integration of the Slow Food movement with touristic agents constitute a partnership that can contribute positively to the gastronomic tourism development.

    With respect to food safety, many works have studied the effectiveness of self-monitoring plans of food companies, designed using the Hazard Analysis and Critical Control Point (HACCP) method. On the other hand, in-depth research has not been made concerning the adherence of the plans to HACCP standards. During our research, we evaluated 116 self-monitoring plans adopted by food companies located in the territory of the Local Health Authority (LHA) of Foggia, Italy. The general errors (terminology, philosophy and redundancy) and the specific errors (transversal plan, critical limits, hazard specificity, and lack of procedures) were standardized. Concerning the general errors, terminological errors pertain to half the plans examined, 47% include superfluous elements and 60% have repetitive subjects. With regards to the specific errors, 77% of the plans examined contained specific errors. The evaluation has pointed out the lack of comprehension of the HACCP system by the food companies and has allowed the Servizio di Igiene degli Alimenti e della Nutrizione (Food and Nutrition Health Service), in its capacity as a control body, to intervene with the companies in order to improve designing HACCP plans.

    2014-05-01

    In recent years, consumer concerns on environmental and health issues related to food products have increased and, as a result, the demand for organically grown production has grown. Results indicate that consumers concerned about healthy diet and environmental degradation are the most likely to buy organic food, and are willing to pay a high premium. Therefore, it is important to ensure the quality of the produce, especially for highly consumed products. The tomato (Lycopersicon esculentum) is one of the most widely consumed fresh vegetables in the world. It is also widely used by the food industries as a raw material for the production of derived products such as purees or ketchup. Consequently, many investigations have addressed the impact of plant nutrition on the quality of tomato fruit. The concentrations of minerals (P, Na, K, Ca and Mg) and trace elements (Cu, Zn and Mn) were determined in tomatoes grown organically in East Georgia, Marneuli District. The contents of minerals and Mn seem to be in the range as shown in literature. Cu and Zn were found in considerably high amounts in comparison to maximum permissible values established in Georgia. Some correlations were observed between the minerals and trace elements studied. K and Mg were strongly correlated with Cu and Zn. Statistically significant difference have shown also P, K and Mg based between period of sampling.

    Based on a preliminary survey in Grobogan Central Java, one of the local food that has a prospective nutrient content developed is freshwater clams. Results of PSG report in 2015, especially in Grobogan district with stunting problem of 31.5% consisting of 7.2% very short and 24.1% short. From the stunting event factor, the role of weaning food in the form of baby porridge is the most important component in the fulfillment of infant nutrition. The research is divided into two stages of the research is the initial stage to make the formulation process by way of freshwater clams, nutrient analysis, and formula calculation. The second stage is the process of formulation weaning food by way of formula making, nutrient analysis, and acceptance test of weaning food on the baby slurry is substituted by the freshwater clams. The influence statistically different substitution of freshwater clams on protein content (p=0.014), fat (p=0,041), carbohydrate (p=0,039), water (p=0,0001), ash (p=0.0001), iron (p=0.0001), and zinc (p=0.0001). There is no influence substitution of freshwater clams on energy content (p=0,129) and fiber (p=0,225). The percentage of favorite level on the acceptance test of color (p=0,005) and taste (p=0,006) was statistically different, but there was no difference flavour (p=0,913) and texture (p=0,198). freshwater clams flour is rich in iron and zinc content, so it can serve as local food, especially in Grobogan Central Java as a stunting handling. Obtained from the results of several formulations substituted of freshwater clams in formulation 2 is a formula that can meet the standards of KEPMENKES except on the content of protein and moisture content. Formula 2 acceptable to the panelists, except for the assessment of taste.

    2016-01-01

    Improvement in nutrient recycling in agriculture is essential to maintain food production while minimising nutrient pollution of the environment. For this purpose, understanding and modelling nutrient cycles in food and related agro-industrial systems is a crucial task. Although nutrient management has been addressed at the plot and farm scales for many years now in the agricultural sciences, there is a need to upscale these approaches to capture the additional drivers of nutrient cycles that may occur at the local, i.e. district, scale. Industrial ecology principles provide sound bases to analyse nutrient cycling in complex systems. However, since agro-food social-ecological systems have specific ecological and social dimensions, we argue that a new field, referred to as “Agro-Industrial Ecology”, is needed to study these systems. In this paper, we review the literature on nutrient cycling in complex social-ecological systems that can provide a basis for Agro-Industrial Ecology. We identify and describe three major approaches: Environmental Assessment tools, Stock and Flow Analysis methods and Agent-based models. We then discuss their advantages and drawbacks for assessing and modelling nutrient cycles in agro-food systems in terms of their purpose and scope, object representation and time-spatial dynamics. We finally argue that combining stock-flow methods with both agent-based models and environmental impact assessment tools is a promising way to analyse the role of economic agents on nutrient flows and losses and to explore scenarios that better close the nutrient cycles at the local scale. - Highlights: • An Agro-Industrial Ecology perspective is essential to model local agro-food systems. • We provide a classification of nutrient (N, P) models, methods and assessment tools. • We distinguished Environmental Assessment, Stock and flow and Agent-based approaches. • The pros and cons of these nutrient cycle models, methods and tools are discussed.

Data included in audit reports have been analyzed with Excel software, classifying detected non compliances (n.c. in 8 categories linked to specific food safety risk factors (structure, operative hygiene, personnel hygiene, pest control, temperature control, management of by-products, traceability, HACCP/records. By the time of the audit 83% of the inspected premises showed structural n.c.; structural aspects are the most critical point (121 n.c. out of 264, followed by operative hygiene (25% of total n.c. and pest control (13.6%. By the time of the second audit series, however, occurred a significant reduction of n.c. in both processing plants and abattoirs, falling from 264 to152, with a reduction of n.c. detection of more than 40%. The best response capacity among operators is related to pest control and HACCP plan/records. The audit procedure implemented, a part from providing a comprehensive and objective evaluation method of the food safety management system put in place by the operators, allowed, if compared to former procedures, a more objective and comprehensive evaluation of the n.c. trend and therefore of the food safety risk factors, estimating the efficacy of the control activity.

  16. Perceived health properties of wild and cultivated food plants in local and popular traditions of Italy: A review.

    Science.gov (United States)

    Guarrera, P M; Savo, V

    2013-04-19

    Many wild and cultivated plants are rich in mineral elements and bioactive compounds and are consumed for health purposes. Studies have demonstrated the curative properties of many of these food plants. In this paper, we discuss the properties of several plants with potential health benefits that have previously received little attention. This review provides an overview and critical discussion of food plants perceived by informants (emic view) as healthy or used as 'food medicine' in Italy. Pharmacological activity of these plants is explored, based upon published scientific research (etic view). Preparation methods, taste perception, toxicity and various potentialities of some food plants are also discussed. The present review includes literature available from 1877 to 2012. The information was collected from books, scientific papers, and abstracts that reported any plants used as food medicine in Italy. The perceived health properties were analyzed in the framework of recent international phytochemical and phytopharmacological literature. A total of 67 edible wild plants and 18 cultivated vegetables, distributed into 20 families, were reported by informants (in literature). Several plants were highly cited (e.g., Taraxacum officinale Webb., Crepis vesicaria L., Allium cepa L., Allium sativum L.). The most frequent health properties attributed to edible plants by the informants were: laxative (22 species), diuretic (15), digestive (11), galactagogue (8), antitussive (cough) (8), hypotensive (7), tonic (7), sedative (7), hypoglycemic (6). Some edible plants are promising for their potential health properties, such as Crepis vesicaria L., Sanguisorba minor Scop. and Sonchus oleraceus L. Several wild species were perceived by informants to maintain health but have never been studied from a phytochemical or pharmacological point of view: e.g., Asparagus albus L., Crepis leontodontoides All., Hyoseris radiata L. subsp. radiata, Phyteuma spicatum L.

    2012-06-01

    Full Text Available The aim of this study was to analyze the production of sago, to analyze its chemical composition and nutrient content, and to analyze the rainfall infiltration capacity of sago baruk palm grown at different altitudes. The research was conducted from October 2010 to June 2011 in Gunung Village, Tabukan Tengah, district of Sangihe. The village is laid from the coast to the top of the hill with an altitude of ±600 m above sea level. The data analysis techniques used in this research were descriptive analyses and F test ANOVA. The results showed that sago stem weight and pith weight were significantly influenced by the altitudes. The heaviest stem weight was obtained at the bottom position, while the heaviest pith weight was obtained at the top position, and for the largest ratio of sago flour to palm stem was obtained at the top position. The chemical compositions were significantly different in the levels of protein, calcium, iron, magnesium, and pH at the three altitudes. The infiltration capacity near the cluster was higher than that of the outside cluster, both in dry and rainy seasons.

    Full Text Available Abstract A comparative food ethnobotanical study was carried out in twenty-one local communities in Italy, fourteen of which were located in Northern Italy, one in Central Italy, one in Sardinia, and four in Southern Italy. 549 informants were asked to name and describe food uses of wild botanicals they currently gather and consume. Data showed that gathering, processing and consuming wild food plants are still important activities in all the selected areas. A few botanicals were quoted and cited in multiple areas, demonstrating that there are ethnobotanical contact points among the various Italian regions (Asparagus acutifolius, Reichardia picroides, Cichorium intybus, Foeniculum vulgare, Sambucus nigra, Silene vulgaris, Taraxacum officinale, Urtica dioica, Sonchus and Valerianella spp.. One taxon (Borago officinalis in particular was found to be among the most quoted taxa in both the Southern and the Northern Italian sites. However, when we took into account data regarding the fifteen most quoted taxa in each site and compared and statistically analysed these, we observed that there were a few differences in the gathering and consumption of wild food plants between Northern and Southern Italy. In the North, Rosaceae species prevailed, whereas in the South, taxa belonging to the Asteraceae, Brassicaceae, and Liliaceae s.l. families were most frequently cited. We proposed the hypothesis that these differences may be due to the likelihood that in Southern Italy the erosion of TK on wild vegetables is taking place more slowly, and also to the likelihood that Southern Italians' have a higher appreciation of wild vegetables that have a strong and bitter taste. A correspondence analysis confirmed that the differences in the frequencies of quotation of wild plants within the Northern and the Southern Italian sites could be ascribed only partially to ethnic/cultural issues. An additional factor could be recent socio-economic shifts, which may be having

    Full Text Available Background The wide use of pesticides raises concerns on the health risks associated with pesticide exposure. For developing countries, like Thailand, pesticide monitoring program (in vegetables and fruits and also the maximum residue limits (MRL regulation have not been entirely implemented. The MRL is a product limit, not a safety limit. The MRL is the maximum concentration of a pesticide residue (expressed as mg/kg recommended by the Codex Alimentarius Commission to be legally permitted in or on food commodities and animal feeds (Codex Alimentarius Commission, 2015; European Commission, 2015. MRLs are based on supervised residue trial data where the pesticide has been applied in accordance with GAP (Good Agricultural Practice. This study aims at providing comparison data on pesticide residues found in three commonly consumed vegetables (Chinese kale, pakchoi and morning glory purchased from some local markets and supermarkets in Thailand. Methods These vegetables were randomly bought from local markets and supermarkets. Then they were analyzed for the content of 28 pesticides by using GC-MS/MS. Results Types of pesticides detected in the samples either from local markets or supermarkets were similar. The incidence of detected pesticides was 100% (local markets and 99% (supermarkets for the Chinese kale; 98% (local markets and 100% (supermarkets for the pakchoi; and 99% (local markets and 97% (supermarkets for the morning glory samples. The pesticides were detected exceeding their MRL at a rate of 48% (local markets and 35% (supermarkets for the Chinese kale; 71% (local markets and 55% (supermarkets for the pakchoi, and 42% (local markets and 49% (supermarkets for the morning glory. Discussion These rates are much higher than those seen in developed countries. It should be noted that these findings were assessed on basis of using criteria (such as MRL obtained from developed countries. Our findings were also confined to these vegetables sold

    Training paradigms affecting Aplysia withdrawal reflexes cause changes in gene expression leading to long-term memory formation in primary mechanoafferents that initiate withdrawal. Similar mechanoafferents are also found in the buccal ganglia that control feeding behavior, raising the possibility that these mechanoafferents are a locus of memory formation after a training paradigm affecting feeding. Buccal ganglia mechanoafferent neurons expressed increases in mRNA expression for the transcription factor ApC/EBP, and for the growth factor sensorin-A, within the first 2 h after training with an inedible food. No increases in expression were detected in the rest of the buccal ganglia. Increased ApC/EBP expression was not elicited by food and feeding responses not causing long-term memory. Increased ApC/EBP expression was directly related to a measure of the efficacy of training in causing long-term memory, suggesting that ApC/EBP expression is necessary for the expression of aspects of long-term memory. In behaving animals, memory is expressed as a decrease in the likelihood to respond to food, and a decrease in the amplitude of protraction, the first phase of consummatory feeding behaviors. To determine how changes in the properties of mechanoafferents could cause learned changes in feeding behavior, synaptic contacts were mapped from the mechanoafferents to the B31/B32 neurons, which have a key role in initiating consummatory behaviors and also control protractions. Many mechanoafferents monosynaptically and polysynaptically connect with B31/B32. Monosynaptic connections were complex combinations of fast and slow excitation and/or inhibition. Changes in the response of B31/B32 to stimuli sensed by the mechanoafferent could underlie aspects of long-term memory expression.

  3. Food allergy alters jejunal circular muscle contractility and induces local inflammatory cytokine expression in a mouse model

    Full Text Available Abstract Background We hypothesized that food allergy causes a state of non-specific jejunal dysmotility. This was tested in a mouse model. Methods Balb/c mice were epicutaneously sensitized with ovalbumin and challenged with 10 intragastric ovalbumin administrations every second day. Smooth muscle contractility of isolated circular jejunal sections was studied in organ bath with increasing concentrations of carbamylcholine chloride (carbachol. Smooth muscle layer thickness and mast cell protease-1 (MMCP-1 positive cell density were assayed histologically. Serum MMCP-1 and immunoglobulins were quantified by ELISA, and mRNA expressions of IFN-γ, IL-4, IL-6 and TGFβ-1 from jejunal and ileal tissue segments were analyzed with quantitative real-time PCR. Results Ovalbumin-specific serum IgE correlated with jejunal MMCP-1+ cell density. In the allergic mice, higher concentrations of carbachol were required to reach submaximal muscular stimulation, particularly in preparations derived from mice with diarrhoea. Decreased sensitivity to carbachol was associated with increased expression of IL-4 and IL-6 mRNA in jejunum. Smooth muscle layer thickness, as well as mRNA of IFN-γ and TGF-β1 remained unchanged. Conclusion In this mouse model of food allergy, we demonstrated a decreased response to a muscarinic agonist, and increased levels of proinflammatory IL-6 and Th2-related IL-4, but not Th1-related IFN-γ mRNAs in jejunum. IgE levels in serum correlated with the number of jejunal MMCP-1+ cells, and predicted diarrhoea. Overall, these changes may reflect a protective mechanism of the gut in food allergy.

    Food items locally grown near Perth, Ontario and grocery store produce and locally grown items from the Pickering-Ajax area in the vicinity of the Pickering Nuclear Generating Station (PNGS) have been analyzed for free water tritium (HTO) and organically bound tritium (OBT). The technique of measuring 3 He ingrowth in samples by mass spectrometry has been used because of its sensitivity and freedom from opportunity for contamination during processing and measurement. Concentrations observed at each site were of the order expected on the basis of known levels of tritium in the local atmosphere and precipitation. There was considerable variation between different materials and limited correlation between materials of a single type. (author). 10 refs., 8 tabs., 4 figs

    2012-05-01

    According to the United Nations (UN), 25 million children linear programming (LP) analysis was developed and piloted in the design of a RUTF prototype for the treatment of wasting in East African children and adults. The LP objective function and decision variables consisted of the lowest formulation price and the weights of the chosen commodities (soy, sorghum, maize, oil, and sugar), respectively. The LP constraints were based on current UN recommendations for the macronutrient content of therapeutic food and included palatability, texture, and maximum food ingredient weight criteria. Nonlinear constraints for nutrient ratios were converted to linear equations to allow their use in LP. The formulation was considered accurate if laboratory results confirmed an energy density difference <10% and a protein or lipid difference <5 g · 100 g(-1) compared to the LP formulation estimates. With this test prototype, the differences were 7%, and 2.3 and -1.0 g · 100 g(-1), respectively, and the formulation accuracy was considered good. LP can contribute to the design of ready-to-use foods (therapeutic, supplementary, or complementary), targeting different forms of malnutrition, while using commodities that are cheaper, regionally available, and meet local cultural preferences. However, as with all prototype feeding products for medical use, composition analysis, safety, acceptability, and clinical effectiveness trials must be conducted to validate the formulation.

    Head and neck cancer patients commonly suffer from severe malnutrition at the time of tentative diagnosis. Percutaneous Endoscopic Gastrostomy [PEG] feeding is now considered as an efficient tool to reduce nutritional deterioration alongside concurrent treatment. We undertook the challenge to retrospectively evaluate the impact of a commercial, disease-specific, feeding formula [Supportan, Fresenius Kabi, Hellas] versus blenderized family food on nutritional outcome. This is a retrospective analysis of prospectively collected nutritional and anthropometric data at the time of PEG placement, at the 8th week [after treatment termination] and at 8 months [6mo of recovery from treatment]. All patients were prescribed a commercial feeding formula. The final dataset included 212 patients: 112 received the commercial formula, 69 voluntarily decided to switch into blenderized-tube-feeding, and 31 were prescribed to receive a home-made formula of standard ingredients. The commercial formula seemed to help patients to fight the catabolism of concurrent treatment, since, at the 8mo assessment, both Body Mass index and Fat Free Mass had almost recovered to the values at the time of first diagnosis. Neither group on blenderized or home-made formulas exhibited nutritional improvement, but experienced a significant deterioration throughout the study period, with the home-made formula group being the worst. These findings clearly indicate that home-made and blenderized foods do not adequately support the nutritional requirements of patients with HNC scheduled to receive concurrent CRT treatment.

    The use of Lactobacillus rhamnosus GR-1 and micronutrients has been associated with a preserved immune function among people living with HIV. However, use of these products in the developing world remains limited due to the lack of facilities for production. We describe the development of a yogurt with L. rhamnosus GR-1 at >7×10(7) colony forming units fortified with locally grown Moringa oleifera leaves at 20% of the recommended daily allowance of vitamin A. The product was made by preparing a thin paste of Moringa which was then incubated with 4% probiotic and 2% yogurt mother culture in milk for 6 hours. The addition of M. oleifera enhanced the survival of probiotic bacteria in yogurt during the shelf life period at 5 °C (P=0.02), but had no effect on probiotic survival at 21 °C. While the sensory characteristics of probiotic and non-probiotic supplemented Moringa yogurts were indistinguishable, the addition of Moringa reduced consumer acceptance compared to regular yogurt.

    The aluminium-deficient and ferrosilicate zeolite-type materials were synthesized by hydrothermal process at 150-170 degree C for various periods of time from the mixtures containing colloidal reactive silica, sodium aluminate, sodium hydroxide, iron nitrate and organic templates. Organic polycation templates were used as zeolite crystal shape modifiers to enhance relative growth rates. The template was almost completely removed from the zeolite specimens by calcination at 550 degree C for 8h in air. Simultaneous thermogravimetric (TG) and differential thermal analysis (DTA) was performed to study the removal of water molecules and the amount of organic template cations occluded inside the crystal pore of zeolite framework. The 12-13% weight loss in the range of (140-560 degree C) was associated with removal of the (C/sub 3/H/sub 7/)/sub 4/ N+ cation and water molecules. X-ray diffraction (XRD) analysis and scanning electron microscope (SEM) techniques were employed to study the structure, morphology and surface features of hydrothermally grown aluminium-deficient and ferrosilicate zeolite-type crystals. In order to elucidate the mode of zeolite crystallization the crystallinity and unit cell parameters of the materials were determined by XRD, which are the function of Al and Fe contents of zeolites.

MÉTODOS: Estudo transversal, realizado com empresas cadastradas no Programa de Alimentação do Trabalhador na cidade de São Paulo. Foram aplicados aos gestores locais (responsáveis pela alimentação do trabalhador questionários semi-estruturados. Os dados foram tabulados por meio da técnica do discurso do sujeito coletivo, utilizando-se três figuras metodológicas: idéia central, expressões-chave e o discurso do sujeito coletivo. RESULTADOS: Os discursos dos gestores de 70 empresas indicaram que 60% das idéias centrais expressaram desconhecimento sobre o Programa e seus objetivos, ou tinham como representação os benefícios para empresa. Entretanto, observou-se que a idéia central mais freqüente foi: "é um programa para fornecer alimentação balanceada para o trabalhador", representando um discurso com ênfase na promoção de alimentação saudável e saúde, que se aproxima dos objetivos do Programa. CONCLUSÕES: A maioria dos discursos não teve ênfase na promoção de alimentação saudável e saúde.

    Within a project aimed to reintroduce non-drug hemp cultivars in the Italian Po valley, for fibre but also high added-value nutraceutical production, investigation on locally grown plants has been performed, in order to assess their oil and metabolic content. This study provides useful information regarding three different hemp cultivars, from two sites, in view of their potential industrial application. The oil was characterised by a high unsaturated/saturated fatty acid ratio and by an almost perfect balance of ω-3 and ω-6 fatty acids, as requested for healthy foods. The alcoholic extracts, for which a high content of amino acids and phenolic compounds has been highlighted, could provide dietary supplements to help in preventing oxidative stress. By investigating the Carmagnola cultivar, six known and four new lignanamides have been identified, confirming and assessing the general metabolic pattern in the seeds of these locally grown plants.

    Full Text Available Human retinal pigment epithelial (hRPE cells have been tested as a cell-based therapy for Parkinson’s disease but will require additional study before further clinical trials can be planned. We now show that the long-term survival and neurotrophic potential of hRPE cells can be enhanced by the use of FDA-approved plastic-based microcarriers compared to a gelatin-based microcarrier as used in failed clinical trials. The hRPE cells grown on these plastic-based microcarriers display several important characteristics of hRPE found in vivo: (1 characteristic morphological features, (2 accumulation of melanin pigment, and (3 high levels of production of the neurotrophic factors pigment epithelium-derived factor (PEDF and vascular endothelial growth factor-A (VEGF-A. Growth of hRPE cells on plastic-based microcarriers led to sustained levels (>1 ng/ml of PEDF and VEGF-A in conditioned media for two months. We also show that the expression of VEGF-A and PEDF is reciprocally regulated by activation of the GPR143 pathway. GPR143 is activated by L-DOPA (1 μM which decreased VEGF-A secretion as opposed to the previously reported increase in PEDF secretion. The hRPE microcarriers are therefore novel candidate delivery systems for achieving long-term delivery of the neuroprotective factors PEDF and VEGF-A, which could have a value in neurodegenerative conditions such as Parkinson’s disease.

    A pot experiment in six open-top chambers with two levels of CO 2 and two multi-metal contaminated soils was conducted to investigate combined effects of elevated CO 2 levels and metals (Cu and Cd) on rice. Elevated CO 2 significantly increased the total dry weight biomass of six Chinese rice by 20-108 and 32-142% for low and high levels of contaminated soils, respectively. We observed dilution/little varied phenomena in grain Cu concentration in six rice varieties grown on both contaminated soils under elevated CO 2 . We found significantly higher Cd concentrations in the parts of three rice varieties under elevated CO 2 , but lower levels for the others. Two major conclusions can be drawn from our study: (1) rice varieties with significantly increased biomass and metal uptake under elevated CO 2 exhibit greater potential for phytoextraction and (2) given expected global increases in CO 2 concentration, CO 2 -induced accumulation of metals in rice might be a component contributing to the potential health risk in the future, with Cd being a more important threat to human health than Cu.

    Full Text Available The economy of the Ukrainian SSR and the western region, according to most indicators, continued to develop on its own basis, solving ordinary socio-political and socio-economic challenges. In 1960-1980s of the twentieth century the two types of reproduction were combined: extensive sources of growth (exploitation of new natural and labour resources, and intensive ones which improved production structure and management system. Western region of the republic developed rapidly, engineering and instrumentation grew, as well as oil and gas and chemical industries, together with consumer goods and food industry, local industry. However, low quality, inadequate technologies reduced the positive impact of these industries on economic efficiency. In addition, other problems arose. As a result tasks of economic development planned by the third Programme of the Communist Party of the Soviet Union turned out to be unfulfilled. Despite a slight increase in industrial growth its rate declined. A large-scale restructuring of the economy on resource conservation, introduction of new technologies began in industrialized countries. Scientific progress in the USSR stalled. It should be noted that attempts to improve the situation were done over and over, but they were not in the economic and scientific spheres but in the political one. The crisis in industry and agriculture of the USSR in the second half of 1980s went far beyond purely production problems, took on socio-economic character and became threatening as for the provision of the country with necessary goods and food, creating social tension. In the late 1980s food consumption per capita decreased, and deficit in manufactured goods increased. Investing activities of villages almost stopped. Employees from the village began to massively lose stable jobs and reliable source of income. The decline in agricultural production led to idle capacity of the food and consumer goods industry, decline in employment

    Poor feeding practices result in inadequate nutrient intakes in young children in developing countries. To improve practices, local food-based complementary feeding recommendations (CFR) are needed. This cross-sectional survey aimed to describe current food consumption patterns of 12-23-month-old Myanmar children (n 106) from Ayeyarwady region in order to identify nutrient requirements that are difficult to achieve using local foods and to formulate affordable and realistic CFR to improve dietary adequacy. Weekly food consumption patterns were assessed using a 12-h weighed dietary record, single 24-h recall and a 5-d food record. Food costs were estimated by market surveys. CFR were formulated by linear programming analysis using WHO Optifood software and evaluated among mothers (n 20) using trial of improved practices (TIP). Findings showed that Ca, Zn, niacin, folate and Fe were 'problem nutrients': nutrients that did not achieve 100 % recommended nutrient intake even when the diet was optimised. Chicken liver, anchovy and roselle leaves were locally available nutrient-dense foods that would fill these nutrient gaps. The final set of six CFR would ensure dietary adequacy for five of twelve nutrients at a minimal cost of 271 kyats/d (based on the exchange rate of 900 kyats/USD at the time of data collection: 3rd quarter of 2012), but inadequacies remained for niacin, folate, thiamin, Fe, Zn, Ca and vitamin B6. TIP showed that mothers believed liver and vegetables would cause worms and diarrhoea, but these beliefs could be overcome to successfully promote liver consumption. Therefore, an acceptable set of CFR were developed to improve the dietary practices of 12-23-month-old Myanmar children using locally available foods. Alternative interventions such as fortification, however, are still needed to ensure dietary adequacy of all nutrients.

    Traceability of food implies the ability to trace and follow a food, feed, or a food-producing animal or substance intended to be, or expected to be, incorporated into a food or feed, through all stages of production, processing, and distribution. The importance of traceability has grown due to the

    The objective of this study was to investigate adolescents' perspectives about the environmental impacts of food production practices and whether these perspectives are related to their food choice. Food choice was operationalized as consumption and purchase of organic foods and locally grown foods. A survey questionnaire was administered to a convenience sample of adolescents and analyzed for descriptive information and relationships among variables. Subjects were 651 ethnically diverse, urban and suburban high school senior students in a major metropolitan area. Variables of an Expanded Theory of Planned Behavior were measured including beliefs, attitudes, perceived social influences, motivation to comply, perceived behavioral control, self-identity, perceived responsibility, behavioral intention, and behavior. Descriptive statistics, Pearson correlation coefficients, and stepwise multiple regression analyses were used. Surveyed adolescents did not have strong or consistent beliefs or attitudes about the environmental impact of food production practices. Cognitive-motivational processes were at work, however, since their perspectives were significantly correlated with behavioral intentions and food choice behaviors. Behavioral intention was best accounted for by attitudes and perceived social influences (and perceived responsibility for organic food), and behavior was best accounted for by behavioral intentions, beliefs, and perceived social influences (and self-identity for local food). There is a need to make salient to adolescents the environmental impact of food production practices through both cognitive and experiential approaches.

    A case study has been performed which involved the full chain assessment from policy drivers to health effect quantification of lead exposure through locally produced food on loss of IQ in pre-school children at the population level across the EU-27, including monetary valuation of the estimated health impact. Main policy scenarios cover the period from 2000 to 2020 and include the most important Community policy developments expected to affect the environmental release of lead (Pb) and corresponding human exposure patterns. Three distinct scenarios were explored: the emission situation based on 2000 data, a business-as-usual scenario (BAU) up to 2010 and 2020 and a scenario incorporating the most likely technological change expected (Most Feasible Technical Reductions, MFTR) in response to current and future legislation. Consecutive model calculations (MSCE-HM, WATSON, XtraFOOD, IEUBK) were performed by different partners on the project as part of the full chain approach to derive estimates of blood lead (B-Pb) levels in children as a consequence of the consumption of local produce. The estimated B-Pb levels were translated into an average loss of IQ points/child using an empirical relationship based on a meta-analysis performed by Schwartz (1994). The calculated losses in IQ points were subsequently further translated into the average cost/child using a cost estimate of €10.000 per loss of IQ point based on data from a literature review. The estimated average reduction of cost/child (%) for all countries considered in 2010 under BAU and MFTR are 12.16 and 18.08% as compared to base line conditions, respectively. In 2020 the percentages amount to 20.19 and 23.39%. The case study provides an example of the full-chain impact pathway approach taking into account all foreseeable pathways both for assessing the environmental fate and the associated human exposure and the mode of toxic action to arrive at quantitative estimates of health impacts at the individual and

    Local-scale opportunities to address challenges of the water-food nexus in the developing world need to be embraced. Borehole-garden permaculture is advocated as one such opportunity that involves the sustainable use of groundwater spilt at hand-pump operated borehole supplies that is otherwise wasted. Spilt water may also pose health risks when accumulating as a stagnant pond. Rural village community use of this grey-water in permaculture projects to irrigate borehole gardens is proposed to primarily provide economic benefit whereby garden-produce revenue helps fund borehole water-point maintenance. Water-supply sustainability, increased food/nutrition security, health protection from malaria, and business opportunity benefits may also arise. Our goal has been to develop an, experience-based, framework for delivery of sustainable borehole-garden permaculture and associated benefits. This is based upon data collection and permaculture implementation across the rural Chikwawa District of Malawi during 2009-17. We use, stakeholder interviews to identify issues influencing uptake, gathering of stagnant pond occurrence data to estimate amelioration opportunity, quantification of permaculture profitability to validate economic potential, and critical assessment of recent permaculture uptake to identify continuing problems. Permaculture was implemented at 123 sites representing 6% of District water points, rising to 26% local area coverage. Most implementations were at, or near, newly drilled community-supply boreholes; hence, amelioration of prevalent stagnant ponds elsewhere remains a concern. The envisaged benefits of permaculture were manifest and early data affirm projected garden profitability and spin-off benefits of water-point banking and community micro-loan access. However, a diversity of technical, economic, social and governance issues were found to influence uptake and performance. Example issues include greater need for improved bespoke garden design input

    Food samples were taken from commercial markets and analyzed for stable element content. The concentrations of most stable elements (Ag, Al, As, Au, Ba, Br, Ca, Ce, Cl, Co, Cr, Cs, Cu, Fe, Hf, I, K, La, Mg, Mn, Mo, Na, Rb, Sb, Sc, Se, Sr, Ta, Th, Ti, V, Zn, Zr) were determined using multiple-element neutron activation analysis, while the concentrations of other elements (Cd, Hg, Ni, Pb) were determined using atomic absorption. The relevance of the concentrations found are noted in relation to other literature values. An earlier study was extended to include the determination of the concentration of stable elements in home-grown products in the vicinity of the Oak Ridge National Laboratory. Comparisons between the commercial and local food-stuff values are discussed

    Specific oral tolerance induction (SOTI) for IgE-mediated food allergy (IFA) can be successfully achieved using interfero gamma (classic SOTI). In this study, a tolerable dose was introduced during tolerance induction with interferon gamma (dual SOTI), and its effectiveness was evaluated. The study population comprised 25 IFA patients. Blood samples were taken for analysis, including complete blood count with differential counts of eosinophils, serum total IgE levels, and specific IgE for allergenic foods. Skin prick tests were conducted with the allergens. Oral food challenges were performed to diagnose IFA. Ten patients received dual SOTI, 5 received classic SOTI, 5 received SOTI without interferon gamma (original SOTI), and 5 were not treated (controls). Patients treated with dual SOTI and classic SOTI using interferon gamma became tolerant to the allergenic food. The tolerable dose was introduced successfully in dual SOTI. It was difficult to proceed with the same dosing protocol used for classic SOTI in cases treated with original SOTI. Following dual SOTI, the systemic reaction to oral intake subsided, but the local skin reaction to contact with the allergenic food persisted. Dual SOTI is an improved protocol for SOTI using interferon gamma for IFA.The local skin reaction and systemic reaction to oral intake were dissociated following dual SOTI. In cases of food allergy, tolerance appears to result from desensitization to allergens.

    Fruit and vegetable intake is inversely correlated with risks for several chronic diseases in humans. Phytochemicals, and in particular, phenolic compounds, present in plant foods may be partly responsible for these health benefits through a variety of mechanisms. Since environmental factors play a role in a plant's production of secondary metabolites, it was hypothesized that an organic agricultural production system would increase phenolic levels. Cultivars of leaf lettuce, collards, and pac choi were grown either on organically certified plots or on adjacent conventional plots. Nine prominent phenolic agents were quantified by HPLC, including phenolic acids (e. g. caffeic acid and gallic acid) and aglycone or glycoside flavonoids (e. g. apigenin, kaempferol, luteolin, and quercetin). Statistically, we did not find significant higher levels of phenolic agents in lettuce and collard samples grown organically. The total phenolic content of organic pac choi samples as measured by the Folin-Ciocalteu assay, however, was significantly higher than conventional samples (p lettuce and collards, the organic system provided an increased opportunity for insect attack, resulting in a higher level of total phenolic agents in pac choi.

  9. Food appropriation through large scale land acquisitions

    2014-01-01

    The increasing demand for agricultural products and the uncertainty of international food markets has recently drawn the attention of governments and agribusiness firms toward investments in productive agricultural land, mostly in the developing world. The targeted countries are typically located in regions that have remained only marginally utilized because of lack of modern technology. It is expected that in the long run large scale land acquisitions (LSLAs) for commercial farming will bring the technology required to close the existing crops yield gaps. While the extent of the acquired land and the associated appropriation of freshwater resources have been investigated in detail, the amount of food this land can produce and the number of people it could feed still need to be quantified. Here we use a unique dataset of land deals to provide a global quantitative assessment of the rates of crop and food appropriation potentially associated with LSLAs. We show how up to 300–550 million people could be fed by crops grown in the acquired land, should these investments in agriculture improve crop production and close the yield gap. In contrast, about 190–370 million people could be supported by this land without closing of the yield gap. These numbers raise some concern because the food produced in the acquired land is typically exported to other regions, while the target countries exhibit high levels of malnourishment. Conversely, if used for domestic consumption, the crops harvested in the acquired land could ensure food security to the local populations. (letter)

    There is evidence that food outlet access differs according to level of neighbourhood deprivation but little is known about how individual circumstances affect associations between food outlet access and diet. This study explored the relationship between dietary quality and a measure of overall food environment, representing the balance between healthy and unhealthy food outlet access in individualised activity spaces. Furthermore, this study is the first to assess effect modification of level of educational attainment on this relationship. A total of 839 mothers with young children from Hampshire, United Kingdom (UK) completed a cross-sectional survey including a 20-item food frequency questionnaire to measure diet and questions about demographic characteristics and frequently visited locations including home, children's centre, general practitioner, work, main food shop and physical activity location. Dietary information was used to calculate a standardised dietary quality score for each mother. Individualised activity spaces were produced by creating a 1000m buffer around frequently visited locations using ArcGIS. Cross-sectional observational food outlet data were overlaid onto activity spaces to derive an overall food environment score for each mother. These scores represented the balance between healthy and unhealthy food outlets using weightings to characterise the proportion of healthy or unhealthy foods sold in each outlet type. Food outlet access was dominated by the presence of unhealthy food outlets; only 1% of mothers were exposed to a healthy overall food environment in their daily activities. Level of educational attainment moderated the relationship between overall food environment and diet (mid vs low, p = 0.06; high vs low, p = 0.04). Adjusted stratified linear regression analyses showed poorer food environments were associated with better dietary quality among mothers with degrees (β = -0.02; 95%CI: -0.03, -0.001) and a tendency toward poorer

    Local neighbourhood environments can influence dietary behavior. There is limited evidence focused on older people who are likely to have greater dependence on local areas and may suffer functional limitations that amplify any neighbourhood impact. Using multi-level ordinal regression analysis we investigated the association between multiple dimensions of neighbourhood food environments (captured by fine-detail, foot-based environmental audits and secondary data) and self-reported frequency of fruit and vegetable intake. The study was a cross-sectional analysis nested within two nationally representative cohorts in the UK: the British Regional Heart Study and the British Women's Heart and Health Study. Main exposures of interest were density of food retail outlets selling fruits and vegetables, the density of fast food outlets and a novel measure of diversity of the food retail environment. A total of 1124 men and 883 women, aged 69 - 92 years, living in 20 British towns were included in the analysis. There was strong evidence of an association between area income deprivation and fruit and vegetable consumption, with study members in the most deprived areas estimated to have 27% (95% CI: 7, 42) lower odds of being in a higher fruit and vegetable consumption category relative to those in the least deprived areas. We found no consistent evidence for an association between fruit and vegetable consumption and a range of other food environment domains, including density of shops selling fruits and vegetables, density of premises selling fast food, the area food retail diversity, area walkability, transport accessibility, or the local food marketing environment. For example, individuals living in areas with greatest fruit and vegetable outlet density had 2% (95% CI: -22, 21) lower odds of being in a higher fruit and vegetable consumption category relative to those in areas with no shops. Although small effect sizes in environment-diet relationships cannot be discounted

    Despite chronic underproduction of food in Nepal, more and more agricultural land is abandoned especially in the remote middle hills and mountains. Male and young workers leave the villages for higher wages in the bigger cities or abroad. By now, most villages are mainly populated by women, children and elderly persons maintaining the gardens and fields close to the houses and leave the centenarian terraces fallow. Erosion, vanishing water resources, losses of soil organic carbon and the weakening of the local agro-economy become increasingly problematic. During the rainy season of 2015/16, 86 farmer families from four villages replanted their abandoned terraces with 25,000 mixed trees, mostly Cinnamon, Moringa, Mulberry, Lemon, Michelia, Paulownia, and various nuts. All trees were planted with a blend of organic biochar-based fertilizer and compost, since it was convincingly demonstrated by more than 20 field trials in this region that this was the most plant-growth promoting method. Mulching of the trees with rice straw or thatch grass was generalized. To let the young tries pass the critical seven months of dry season, water retention ponds with pipe irrigation were installed. Farmers were organized in groups of three families to mutually help and control the tree maintenance which led to an average tree survival rate of more than 80% after the first year compared to less than 50% in many country-wide forestation projects since the 1980s. Between the lower and upper lines of trees on the terraces, ginger, turmeric, black beans, onions, lentils and other secondary crops were cultivated using the same organic biochar based fertilizer and mulching techniques. What may seem a reasonable approach for many places, is in many of the poorest countries simply not possible to realize because village families do often not have the necessary initial investment for saplings and irrigation facilities at their disposal. Therefore, the Ithaka Institute linked the forest garden

    Estimating the ingestion of potentially contaminated foodstuffs around conventional and nuclear industrial sites requires data about the food practices and eating habits of the local residents, especially the consumption of locally- and home-produced food. The IRSN thus chose to conduct surveys about these practices in the vicinity of nuclear sites. Their methodology was based on previous surveys near nuclear sites. In 2004, in partnership with AREVA and BEGEAT, the French Institute for Radioprotection and Nuclear Safety studied the eating habits of the residents of Bollene, near the Tricastin plant (Rhone Valley), with the aim of improving the quantification of the plant's potential health impacts. Based on these studies and as part of the SENSIB project to characterize vulnerability to nuclear risks, we developed and tested a survey protocol during the summer 2008, around the Chinon nuclear plant, in collaboration with EDF. The protocol is currently being tested around the Marcoule nuclear plant, in collaboration with the CEA. The aim was to optimize the feasibility and the reproducibility of the approach, while losing none of the robustness of the results. The data obtained made it possible to evaluate daily food intake values for individuals and to assess the rates of consumption of locally-grown products for many food categories. The data showed the existence of local population groups with very high rates of locally-grown food consumption - over 90 % of certain food products. This comparative study thus shows the significant variability of eating habits in the French population and proposes a reproducible approach to evaluating realistic indicators of potentially risky dietary habits.

    Food systems have changed markedly with human settlement and agriculture, industrialisation, trade, migration and now the digital age. Throughout these transitions, there has been a progressive population explosion and net ecosystem loss and degradation. Climate change now gathers pace, exacerbated by ecological dysfunction. Our health status has been challenged by a developing people-environment mismatch. We have regarded ecological conquest and innovative technology as solutions, but have not understood how ecologically dependent and integrated we are. We are ecological creatures interfaced by our sensoriness, microbiomes, shared regulatory (endocrine) mechanisms, immune system, biorhythms and nutritional pathways. Many of us are 'nature-deprived'. We now suffer what might be termed ecological health disorders (EHD). If there were less of us, nature's resilience might cope, but more than 9 billion people by 2050 is probably an intolerable demand on the planet. Future food must increasingly take into account the pressures on ecosystem-dependent food systems, with foods probably less biodiverse, although eating in this way allows optimal health; energy dysequilibrium with less physical activity and foods inappropriately energy dense; and less socially-conducive food habits. 'Personalised Nutrition', with extensive and resource-demanding nutrigenomic, metabolomic and microbiomic data may provide partial health solutions in clinical settings, but not be justified for ethical, risk management or sustainability reasons in public health. The globally prevalent multidimensional malnutritional problems of food insecurity, quality and equity require local, regional and global action to prevent further ecosystem degradation as well as to educate, provide sustainable livelihoods and encourage respectful social discourse and practice about the role of food.

    Locally grown, wild food plants seasonally contribute a considerable portion of the daily diet in certain Mediterranean areas and it has been suggested that the beneficial effects of the Mediterranean diet on human health partly originate from the antioxidant effect of flavonoid-rich food plants. The nutrient content of most wild plants is higher than that of cultivated ones and may vary depending on the prevailing environmental conditions. Accordingly, three local Mediterranean plant foods (i.e. Cichorium intybus, Sonchus oleraceus, Papaver rhoeas) were collected in Greece (Crete), southern Italy, and southern Spain in order to assess possible differences in their in vitro antioxidant potential. The biological assays revealed diverse intra-plant specific antioxidant effects for the tested extracts ranging from no activity to almost complete protection. Furthermore, substantial differences in the polyphenol content were found for the nutritionally used part of the same plant originating from different locations. However, no clear correlations between the polyphenol content and the extracts' antioxidant activities were found. Taken together, the data suggest that certain local Mediterranean plant foods possess promising antioxidant activity and that the observed biological effects are possibly influenced by the geographically-dependent environmental conditions prevailing during plant growth.

    Chicago, the host city for the annual meeting of the RSNA (Radiological Society of North America), is the quintessential place to obtain certain foods, among them deep dish pizza, the Italian beef sandwich, and the Chicago-style hot dog. Given some appropriate nutritional concerns about these items, it is important to realize that healthier alternatives are grown, produced, and sold regionally. Chicago has also for years been known as one of America's great restaurant towns. However, the French delicacy foie gras cannot be found on the menu of any of its five-star establishments, as the sale of this dish became illegal in 2006. Diagnostic imaging offers a unique perspective on the local Chicago cuisine. (c) RSNA, 2007.

    Increasing population and high cost of fuels have created opportunities for using alternate energies for post-harvest processing of foods. Solar food processing is an emerging technology that provides good quality foods at low or no additional fuel costs. A number of solar dryers, collectors and concentrators are currently being used for various steps in food processing and value addition. Society for Energy, Environment and Development (SEED) developed Solar Cabinet Dryer with forced circulation which has been used for dehydration and development of value added products from locally grown fruits, vegetables, leafy greens and forest produce. Drying under simulated shade conditions using UV-reducing Blue filter helps retain nutrients better. Its simple design and ease of handling makes SEED Solar Dryer an ideal choice for application of food processing in rural settings, closer to where the harvest is produced, eliminating the need for expensive transportation or storage of fresh produce. It also creates employment opportunities among the rural population, especially women. Other gadgets based on solar collectors and concentrators currently being used at various steps of food processing are reviewed.

    Introduction Since 2008, several states and municipalities have implemented regulations requiring provision of nutrition information at chain restaurants to address obesity. Although early research into the effect of such labels on consumer decisions has shown mixed results, little information exists on the restaurant industry’s response to labeling. The objective of this exploratory study was to evaluate the effect of menu labeling on fast-food menu offerings over 7 years, from 2005 through 2011. Methods Menus from 5 fast-food chains that had outlets in jurisdictions subject to menu-labeling laws (cases) were compared with menus from 4 fast-food chains operating in jurisdictions not requiring labeling (controls). A trend analysis assessed whether case restaurants improved the healthfulness of their menus relative to the control restaurants. Results Although the overall prevalence of “healthier” food options remained low, a noteworthy increase was seen after 2008 in locations with menu-labeling laws relative to those without such laws. Healthier food options increased from 13% to 20% at case locations while remaining static at 8% at control locations (test for difference in the trend, P = .02). Since 2005, the average calories for an à la carte entrée remained moderately high (approximately 450 kilocalories), with less than 25% of all entrées and sides qualifying as healthier and no clear systematic differences in the trend between chain restaurants in case versus control areas (P ≥ .50). Conclusion These findings suggest that menu labeling has thus far not affected the average nutritional content of fast-food menu items, but it may motivate restaurants to increase the availability of healthier options.

    Since 2008, several states and municipalities have implemented regulations requiring provision of nutrition information at chain restaurants to address obesity. Although early research into the effect of such labels on consumer decisions has shown mixed results, little information exists on the restaurant industry's response to labeling. The objective of this exploratory study was to evaluate the effect of menu labeling on fast-food menu offerings over 7 years, from 2005 through 2011. Menus from 5 fast-food chains that had outlets in jurisdictions subject to menu-labeling laws (cases) were compared with menus from 4 fast-food chains operating in jurisdictions not requiring labeling (controls). A trend analysis assessed whether case restaurants improved the healthfulness of their menus relative to the control restaurants. Although the overall prevalence of "healthier" food options remained low, a noteworthy increase was seen after 2008 in locations with menu-labeling laws relative to those without such laws. Healthier food options increased from 13% to 20% at case locations while remaining static at 8% at control locations (test for difference in the trend, P = .02). Since 2005, the average calories for an à la carte entrée remained moderately high (approximately 450 kilocalories), with less than 25% of all entrées and sides qualifying as healthier and no clear systematic differences in the trend between chain restaurants in case versus control areas (P ≥ .50). These findings suggest that menu labeling has thus far not affected the average nutritional content of fast-food menu items, but it may motivate restaurants to increase the availability of healthier options.

    Full Text Available Cape Verde, an island country with few natural resources and with adverse soil and weather conditions, imports most of the foodstuffs that need. Local production, although scarce, is relevant to food security. This article reflects a case study in the municipality of Ribeira Grande, island of Santo Antão -Cape Verde, whose aim was to study the role of three production systems in the generation of income, food security and improving the quality of life of families. These systems are: vegetable production, rainfed production and sugar cane production. A total of 105 surveys were carried out in the localities of Ribeirão and Garça de Cima, equally distributed among different agricultural producers. It was found that the sugar cane producers have an average annual income superior to horticulture and rainfed farmers, 402,154, 337,602 and 259,764 CVE respectively (1 euro = 110.265 Cape Verdean escudos – CVE. With respect to food intake, the differences are not significant. Horticulture farmers have a calorie intake of 2959.71, rainfed producers 2926.65 and sugar cane producers 2888.86 kcal/EM/day. With regard to indicators of quality of life, the families of horticulture farmers and sugar cane producers present similar results, superior to the rainfed producers’ families.

    Food has become a prominent focus of US public health policy. The emphasis has been almost exclusively on what Americans eat, not what is grown or how it is grown. A field of research, policy, and practice activities addresses the food-health-agriculture nexus, yet the work is still often considered "alternative" to the mainstream. This article outlines the diverse ways in which agriculture affects public health. It then describes three policy issues: farm-to-school programming, sustainability recommendations in the Dietary Guidelines for Americans, and antibiotic use in animal agriculture. These issues illustrate the progress, challenges, and public health benefits of taking a food systems approach that brings together the food, agriculture, and public health fields.

    Full Text Available Aboriginal people in Canada experience disproportionately high rates of diet-related illnesses, such as obesity and diabetes. Food insecurity has been identified as a contributing factor to these illnesses along with a loss of traditional lifestyle. Current food systems within northern subarctic and arctic regions of Canada rely heavily on imported foods that are expensive (when available, and are environmentally unsustainable. A warming subarctic and arctic climate present challenges, but also offers the opportunity for local agricultural production that can increase food security and promote a more sustainable food system. In this study the feasibility of sustainably growing potatoes (Solanum tuberosum L. utilizing agroforestry practices to enhance food security in remote subarctic communities is explored through a case study in Fort Albany First Nation in northern Ontario, Canada. Potato crops were grown over a two-year period and rotated into plots that had been planted with green bush beans (Phaseolus vulgaris L.. Results showed that potatoes and bush beans could be grown successfully in the subarctic without the use of greenhouses with yields comparable to more conventional high-input agricultural methods. In subarctic Canada, sustainable local food production can help to promote social capital, healthier lifestyles, and food security.

    The use of wheat flour as the basic ingredients of food products for high energy high protein diet is considerably high. Soybeans, mung beans, red leaf spinach and moringa leaf is local food sources of nutrients that are potential to be processed into a composite flour substituting wheat flour, which can be utilized for a variety of food products. The research was aimed to know the influence of proportion of soybeans, mung beans, red leaf spinach and moringa leaf (KhiMeLor on the quality of nutrition, protein and organoleptik quality of composite flour. This was experimental research with a complete random design. The treatment were several composition mixtures of wheat and composite flour, consisting of soybean, mung bean, red leaf spinach and moringa leaf P0 (100% : 0%; P1 (75% : 25%; P2 (50% : 50%; P3 (25% : 75%; P4 (0% : 100%. The content of carbohydrate, protein and fat was analyzed using proximate analysis. The quality of protein was examined from limiting amino acid and protein digestibility score. The sensory test was used to examine the costumer acceptance on sensory parameters. Statistical analysis used One Way Anova which  showed that substitution of  soy bean, mung bean,  moringaleaf and red spinach significantly (p=0,000 increases protein level. The limiting amino acid of P0,P1 and P2 was Lysine, but P3 and P4 was methionine. Protein digestibility of composite fluor was less than P0 (96%. The result of sensory evaluation showed that there was significant difference in aroma (p=0,000 and texture (p=0,029 which decreases as there is an increase of proportion composite flour. The conclusion was different proportion of soy bean, mung bean, moringa leaf and red spinach  influences the nutrition quality and sensory evaluation of composite flour.

    Objectives: To determine accuracy of abdominal radiography in locating radiopaque markers in the gastrointestinal tract and to assess correlation between gastric emptying rate of radiopaque markers and that of canned food. Animals: 17 healthy dogs. Procedure: Dogs were fed thirty 1.5-mm markers and ten 5-mm markers mixed in sufficient food to meet 25% of their daily caloric intake. They were then euthanatized by administration of an overdose of barbiturate at 1, 2, 5, 8, or 12 hours after eating and the abdomen was radiographed. The stomach, small intestine, and large intestine were then separated and radiographed in isolation. The wet and dry weights of the stomach contents were determined. The apparent and actual locations of the markers and the gastric emptying rates of markers, wet matter, and dry matter were compared, using rank correlation. Results: All comparisons indicated significant (P 0.92). The mean difference between the apparent and actual locations of the markers was < 3% for all comparisons. The mean difference between the percentage of small markers and large markers retained in the stomach and that of dry matter was 7.8 (SD, 6.2; range, 0 to 18)% and 11.9 (SD, 12.5; range, 0 to 44)%, respectively. Conclusions: The gastric emptying and orocolic transit rates of the markers were accurately predicted by abdominal radiography. The gastric emptying rate of the diet and the small markers and, to a lesser extent, the large markers was closely correlated. Clinical Relevance: When fed with a special canned food diet, radiopaque markers can be used to assess the gastric emptying rate of food with sufficient accuracy for clinical purposes

    This study determined the heavy metals concentration in arable soils and associated food crops around the Pb-Zn mines in Enyigba, Nigeria, and metal transfer factors were calculated. Air-dried samples of the soils and food crops were analyzed for 8 known nutritional and toxic heavy metals by Inductively Coupled Plasma - Mass Spectrometer (ICP-MS) method. Eighty seven percent of all the 20 sampled soils contain Pb in excess of the maximum allowable concentration (MAC) set by Canadian Environmental Quality Guideline (CCME) and European Union (EU) Standard, while Zn in thirty-one percent of the samples exceeded the CCME for MAC of 200 mg/kg. All the food crops, with the exception of yam tuber, contain Pb which exceeded the 0.43 mg/kg and 0.3 mg/kg MAC standards of EU and WHO/FAO respectively, with the leafy vegetables accumulating more Pb than the tubers. The metal transfer factors in the tubers and the leafy vegetables were in the order: Mo > Cu > Zn > Mn > As > Cd > Cr > Ni > Pb and Cd > Cu > Zn > Mn > Mo > As > Ni > Pb > Cr, respectively. Risk assessment studies revealed no health risk in surrounding populations for most of the heavy metals. However, Pb had a high health risk index (HRI) of 1.1 and 1.3, in adults and children, respectively for cassava tuber; Pb had HRI > 1 in lemon grass while Mn also had HRI > 1 in all the leafy vegetables for both adult and children. This high level of HRI for Pb and Mn is an indication that consumers of the food crops contaminated by these metals are at risk of health problems such as Alzheimers' disease and Manganism, associated with excessive intake of these metals. Further systematic monitoring of heavy metal fluxes in cultivable soils around the area of these mines is recommended.

    Full Text Available The contribution is aimed at the assessment of recommended crop management practices of chosen cereals for organic farming. To increase competitiveness, these practices are modified depending on soil and climatic conditions, and on a way of production use. Furthermore, impacts of the recommended crop management practices on economics of growing chosen cereals are evaluated and compared with economic results obtained under conventional farming. It is assumed that achieved results will contribute to the increase in proportion of arable crops in the Czech Republic where organic production offer does not meet current demands.When evaluating results of growing individual cereal species in a selective set of organic farms, triticale, spelt and spring barley (in this ranking can be considered as profitable crops. Moreover, triticale and spelt have even higher gross margin under organic farming than under conventional farming (by 62 % in triticale. Oat brings losses, however, it is important for livestock production. Winter wheat seems to be also unprofitable since less grain is produced at lower imputs per hectare and only part of it is produced in quality “bio”, i.e. marketed for higher prices. Rye also brings losses under organic farming, particularly due to lower yields, similarly to the other mentioned cereals. Special cereal species that are still neglected in organic farming systems are of potential use. Durum wheat has vitreous kernels with a high content of quality gluten which is used for pasta production. It can be grown in the maize production area on fertile soils only.

    Full Text Available Abstract Background Childhood obesity persists in the United States and is associated with serious health problems. Higher rates of obesity among children from disadvantaged households may be, in part, attributable to disparities in access to healthy foods such as fruits and vegetables. Community supported agriculture can improve access to and consumption of fresh produce, but the upfront payment structure, logistical barriers, and unfamiliarity with produce items may inhibit participation by low-income families. The aim of this project is to assess the impact of subsidized, or “cost-offset,” community supported agriculture participation coupled with tailored nutrition education for low-income families with children. Methods/design The Farm Fresh Foods for Healthy Kids community-based, randomized intervention trial will build on formative and longitudinal research to examine the impact of cost-offset community supported agriculture on diet and other health behaviors as well as the economic impacts on local economies. The intervention will involve reduced-price community supported agriculture shares which can be paid for on a weekly basis, nine skill-based and seasonally-tailored healthy eating classes, and the provision of basic kitchen tools. Low income families with at least one child aged 2–12 years will be recruited to join existing community supported agriculture programs in New York, North Carolina, Vermont, and Washington. In each program, families will be randomized 1:1 to intervention or delayed intervention groups. Data will be collected at baseline, and in the fall and spring for 3 years. The primary outcomes are children’s intake of fruits and vegetables and foods high in sugar and/or (solid fat, as well as diet quality; secondary outcomes include physical, behavioral, psychosocial, and environmental variables.

  11. "Everyone just ate good food": 'Good food' in Islamabad, Pakistan.

    Hasnain, Saher

    2018-08-01

    In recent years, consumption of alternatively produced foods has increased in popularity in response to the deleterious effects of rapidly globalising and industrialised food systems. Concerns over food safety in relation to these changes may result from elevated levels of risk and changing perceptions associated with food production practices. This paper explores how the middle class residents of Islamabad, Pakistan, use the concept of 'good food' to reconnect themselves with nature, changing food systems, and traditional values. The paper also demonstrates how these ideas relate to those of organic, local, and traditional food consumption as currently used in more economically developed states in the Global North. Through research based on participant observation and semi-structured interviews, this paper illustrates that besides price and convenience, purity, freshness, association with specific places, and 'Pakistani-ness' were considered as the basis for making decisions about 'good food'. The results show that while individuals are aware of and have some access to imported organic and local food, they prefer using holistic and culturally informed concepts of 'good food' instead that reconnect them with food systems. I argue that through conceptualisations of 'good food', the urban middle class in Islamabad is reducing their disconnection and dis-embeddedness from nature, the food systems, and their social identities. The paper contributes to literature on food anxieties, reconnections in food geography, and 'good food' perceptions, with a focus on Pakistan. Copyright © 2018. Published by Elsevier Ltd.

    2016-06-01

    Full Text Available In a post-industrial economy, it is as important to understand “material” productive processes in the local community as the processes through which global value chains “expropriate” or “co-opt” common immaterial assets. However, the literature on collective action and the management of common goods generally focuses on matters of the control and governance of material resources. The article commences with an analysis of the relations between the production of value, collective action and the rentier nature of contemporary capitalism and its entrepreneurial ideology. Then, we present a detailed analysis of the case of mytilid seed capture in the Reloncaví Estuary (Los Lagos Region, Chile. This case shows us the failure of modernisation policies which are based on converting local producers into modern entrepreneurs. To adopt a successful value strategy, a very different problem must be addressed, namely the difficulties of local communities in managing successfully their own common immaterial values. Faced with the dichotomous logic of neoliberalism, communities must reunite these immaterial values and the associated common material resources, and modulate the friction between them.En una economía postindustrial, es importante comprender los procesos productivos “materiales” en la comunidad local como procesos a través de los cuales las cadenas globales de valor “expropian” o “cooptan” los activos inmateriales comunes. Sin embargo, la literatura sobre acción colectiva y gestión de los bienes comunes generalmente se focaliza en el control y la gobernanza de los recursos materiales. Este artículo comienza con un análisis de las relaciones entre la producción del valor, la acción colectiva y la naturaleza rentista de capitalismo contemporáneo y su ideología emprendedora. A continuación, presentamos un análisis detallado del caso del cultivo de semillas de mitílidos en el Estuario de Reloncaví (Los Lagos, Chile

    Full Text Available Cette recherche s’intéresse à la perception de la qualité des produits alimentaires à travers les relations directes entre producteurs et consommateurs. Elle s’efforce d’apporter un éclairage sur la manière dont se construisent ou se reconstruisent les liens de proximité entre ces acteurs parallèlement à un système de commercialisation plus classique. Elle a plus précisément pour ambition d’étudier l’influence des relations directes entre un producteur et un consommateur sur la manière dont ce dernier perçoit la qualité des produits alimentaires. Pour répondre à ce questionnement nous avons choisi deux terrains différents en fonction de la nature des relations développées : la vente directe de viande de bœuf apparue suite à la crise de la vache folle et l’animation commerciale par des éleveurs de volaille dans les grandes surfaces. Les résultats tendent à montrer d’une part que la dimension relationnelle prend une part effective dans le processus de qualification des produits alimentaires et d’autre part que l’influence qu’elle exerce est très étroitement liée à la nature de la confiance établie entre les acteurs concernés.This research examines how the quality of food products is perceived when there is a direct relationship between the producer and consumer. It attempts to throw light on the way that customer-intimacy links are forged or restored between these two participants in the chain and draws a parallel with the more standard distribution channels. The goal is more precisely to study the influence of direct relationship on consumers’ perception of food quality. To address these issues we have selected two different areas according to the type of relationship developed: the farmer-to-consumer sale of beef that emerged after the BSE crisis and promotional events in the supermarkets organized by chicken farmers.

    Estimating the ingestion of potentially contaminated foodstuffs around conventional and nuclear industrial sites requires data about the food practices and eating habits of the local residents, especially the consumption of locally- and home-produced food. The IRSN thus chose to conduct surveys about these practices in the vicinity of nuclear sites. Their methodology was based on previous surveys near nuclear sites. In 2004, in partnership with AREVA and BEGEAT, the French Institute for Radioprotection and Nuclear Safety studied the eating habits of the residents of Bollene, near the Tricastin plant (Rhone Valley), with the aim of improving the quantification of the plant's potential health impacts. Based on these studies and as part of the SENSIB project to characterize vulnerability to nuclear risks, we developed and tested a survey protocol during the summer 2008, around the Chinon nuclear plant, in collaboration with EDF. The protocol is currently being tested around the Marcoule nuclear plant, in collaboration with the CEA. The aim was to optimize the feasibility and the reproducibility of the approach, while losing none of the robustness of the results. The data obtained made it possible to evaluate daily food intake values for individuals and to assess the rates of consumption of locally-grown products for many food categories. The data showed the existence of local population groups with very high rates of locally-grown food consumption - over 90 % of certain food products. This comparative study thus shows the significant variability of eating habits in the French population and proposes a reproducible approach to evaluating realistic indicators of potentially risky dietary habits.

    Research indicates poor nutrition is a leading determinant of the development of chronic disease, and increasing fruit and vegetable consumption is one method for decreasing obesity. Many policies have focused on increasing the demand for fruits and vegetables through price reductions and coupons. However, without ensuring a stable supply, increased demand can continue to raise prices, crowding out individuals who may otherwise have purchased fruits and vegetables and ultimately leading to continued disparities in access. This paper presents a review of selected state-level policy options recently proposed or implemented in states across the United States, and provides an evidence-based lens through which food access policy can be shaped in the Midwest. This review and potential framework uses Wisconsin to illustrate the feasibility of different state-level decisions and their potential impact on particular populations. Future supply-side policies to consider include expanding Electronic Benefit Transfer to the Special Supplemental Nutrition Program for Women, Infants and Children (WIC),program and farmers markets, incentivizing the purchase of locally grown produce, assisting local specialty farmers directly, and/or establishing a state-level food policy council. This review reveals that a food policy council would create a more sustainable policy analysis process to better ensure future policy adoption is truly comprehensive, encompassing the production, distribution and purchase of locally grown fruits and vegetables.

    Conclusion: Hence, it is imperative that Dayak food is promoted among the local people first. Only when Dayak food is appreciated and accepted by the local people could the food be further promoted to the tourists. This would have a positive impact on the food business and tourism industry in Sarawak and Malaysia.

  3. Declining global per capita agricultural production and warming oceans threaten food security

    Despite accelerating globalization, most people still eat food that is grown locally. Developing countries with weak purchasing power tend to import as little food as possible from global markets, suffering consumption deficits during times of high prices or production declines. Local agricultural production, therefore, is critical to both food security and economic development among the rural poor. The level of local agricultural production, in turn, will be determined by the amount and quality of arable land, the amount and quality of agricultural inputs (fertilizer, seeds, pesticides, etc.), as well as farm-related technology, practices and policies. This paper discusses several emerging threats to global and regional food security, including declining yield gains that are failing to keep up with population increases, and warming in the tropical Indian Ocean and its impact on rainfall. If yields continue to grow more slowly than per capita harvested area, parts of Africa, Asia and Central and Southern America will experience substantial declines in per capita cereal production. Global per capita cereal production will potentially decline by 14% between 2008 and 2030. Climate change is likely to further affect food production, particularly in regions that have very low yields due to lack of technology. Drought, caused by anthropogenic warming in the Indian and Pacific Oceans, may also reduce 21st century food availability in some countries by disrupting moisture transports and bringing down dry air over crop growing areas. The impacts of these circulation changes over Asia remain uncertain. For Africa, however, Indian Ocean warming appears to have already reduced rainfall during the main growing season along the eastern edge of tropical Africa, from southern Somalia to northern parts of the Republic of South Africa. Through a combination of quantitative modeling of food balances and an examination of climate change, this study presents an analysis of emerging

    Providing food through schools has well documented effects in terms of the education, health and nutrition of school children. However, there is limited evidence in terms of the benefits of providing a reliable market for small-holder farmers through "home-grown" school feeding approaches. This study aims to evaluate the impact of school feeding programmes sourced from small-holder farmers on small-holder food security, as well as on school children's education, health and nutrition in Mali. In addition, this study will examine the links between social accountability and programme performance. This is a field experiment planned around the scale-up of the national school feeding programme, involving 116 primary schools in 58 communities in food insecure areas of Mali. The randomly assigned interventions are: 1) a school feeding programme group, including schools and villages where the standard government programme is implemented; 2) a "home-grown" school feeding and social accountability group, including schools and villages where the programme is implemented in addition to training of community based organisations and local government; and 3) the control group, including schools and household from villages where the intervention will be delayed by at least two years, preferably without informing schools and households. Primary outcomes include small-holder farmer income, school participation and learning, and community involvement in the programme. Other outcomes include nutritional status and diet-diversity. The evaluation will follow a mixed method approach, including household, school and village level surveys as well as focus group discussions with small-holder farmers, school children, parents and community members. The impact evaluation will be incorporated within the national monitoring and evaluation (M&E) system strengthening activities that are currently underway in Mali. Baselines surveys are planned for 2012. A monthly process monitoring visits, spot

    Full Text Available Buckwheat is a sixth staple food crop after rice, wheat, maize, finger millet, and barley in Nepal. It is considered as an alternate cereal and poor man’s crop, representing an important food supply in remote places of Himalayas. It is the best crop in higher altitude in terms of adaptation to different climatic variables and easily fitted to different cropping patterns due to short duration. It is cultivated on marginal land in 61 out of 75 districts of Nepal from some 60 m to 4500 m asl, especially hilly and mountain districts like Rukum, Rolpa, Jajarkot, Dolpa, Humla, Jumla, Kalikot, Kavre, Dolakha, and Okhaldhunga. Sweet buckwheat varieties are generally grown in midhill and Terai but Tartary buckwheat varieties are grown in higher altitude. There are altogether 19 local landraces of sweat buckwheat and 37 for Tartary buckwheat listed from Nepal. The largest producers are China, USA, and Russia and Japan is principal user of global buckwheat grown in the world. In Nepal, it is cultivated in 10510 ha area with production of 10355 t/yr and yield of 0.983 t/ha. It has also medicinal value used in different forms including all its parts so the demand of buckwheat is increasing.

    that these destinations appear to conjure up quite generic food place brands where the promotional discourses are conceived as fairly similar thereby giving little substance to local food. The paper concludes with a discussion of alternative promotional discourses aiming at enhancing local food identity.......Drawing on earlier research on local food, terroir, authenticity, food narratives and conformity in branding efforts, we study the place branding strategies of four Danish coastal destinations, each focusing on profiling themselves as food places for tourists. Based on analyses of online food......-related promotional material along the food tourism value chain, overlapping food discourses characterised by terroir typicality and historical references are identified. Differences in food discourses also appear which are critical in view of achieving a distinct food place brand. Moreover, it is argued...

    The common trend of urban population has been growing significantly in Indonesia for decades, are affected by urban green space conversion. Generally, this area is utilized for urban infrastructures and residences. Furthermore, urban area has grown uncontrollably that could enhance the phenomenon of urban sprawl. The conversion of green urban area and agricultural area will significantly decrease urban food security and quality of urban environment. This problem becomes a serious issue for urban sustainability. Bandung is a city with dense population where there are many poor inhabitants. Families living in poverty are subjected to food insecurity caused by the rise of food prices. Based on the urgency of urban food security and urban environment quality the local government has to achieve comprehensive solutions. This research aims to formulate the policy of productive green open space towards food security for poor people in Bandung. This research not only examines the role played by productive green open space to supply food for the urban poor but also how to govern urban areas sustainably and ensure food security. This research uses descriptive explanatory methodology that describes and explains how to generate policy and strategic planning for edible landscape to promote urban food security. Taman Sari is the location of this research, this area is a populous area that has amount of poor people and has a quite worse quality of urban environment. This study shows that urban green open space has the potential to be utilized as an urban farming land, which poor inhabitants could be main actors to manage urban agriculture to provide their food. Meanwhile, local government could contribute to subsidize the financial of urban farming activities.

    Full Text Available This experiment was conducted in parallel with work in the Democratic Republic of the Congo with the objective to evaluate the growth performance and production costs of Nile tilapia fed diets formulated using local plant protein sources, and to compare them to those obtained with an optimized commercial fish feed. Ninety monosex male tilapia juveniles (Oreochromis niloticus; mean weight 17.3 ± 0.2 g; mean length 9.6 ± 0.1 cm were reared in 9 acrylic aquaria supplied by closed water recirculation system. Three diets were tested in triplicate: 1 Rcongo, the test diet formulated by using local feed ingredients collected in the DR-Congo; 2 Rcanada, the diet formulated with the same ingredient composition as the first one, but sourced in Canada; and 3 Rcommercial, a fishmeal-based commercial control diet. In vivo feed digestibility and biochemical analysis of samples were carried out. The effects of diet and rearing time were measured on fish performance, including fish biomass, K coefficient, weight gain (WG, feed efficiency (FE, feed conversion rate (FCR, specific growth rate (SGR, protein efficiency ratio (PER, apparent digestibility coefficient (ADC and on nutrient budget and fish biochemical composition. After four weeks, the fish achieved weight gains of 52% for Rcongo diet (17.2 ± 0.4 to 26.2 ± 2.6 g, 59% for Rcanada diet (17.4 ± 0.1 to 27.6 ± 3.2 g and 153% for the commercial diet (17.3 ± 0.2 to 43.8 ± 2.0 g. The cost-benefit analysis has indicated that the Rcongo diet was economically advantageous, reducing fish production cost up to 36% compared to commercial feed.

    Full Text Available Food allergy is an important public health problem affecting 5% of infants and children in Korea. Food allergy is defined as an immune response triggered by food proteins. Food allergy is highly associated with atopic dermatitis and is one of the most common triggers of potentially fatal anaphylaxis in the community. Sensitization to food allergens can occur in the gastrointestinal tract (class 1 food allergy or as a consequence of cross reactivity to structurally homologous inhalant allergens (class 2 food allergy. Allergenicity of food is largely determined by structural aspects, including cross-reactivity and reduced or enhanced allergenicity with cooking that convey allergenic characteristics to food. Management of food allergy currently focuses on dietary avoidance of the offending foods, prompt recognition and treatment of allergic reactions, and nutritional support. This review includes definitions and examines the prevalence and management of food allergies and the characteristics of food allergens.

    It is uncertain whether multiple micronutrients benefit the mental and psychomotor development of young children in developing countries. We conducted a randomised double-blind controlled trial to evaluate the effect of a richly micronutrient-fortified v. a basal fortified porridge on mental and psychomotor development in Zambian infants. Infants (n 743) were randomised at age 6 months to receive either the richly fortified or the basal fortified infant food and were followed up until 18 months of age. All the infants were evaluated monthly for achievement of a series of developmental milestones. The Bayley scales of infant development II were administered to a subsample of 502 infants at 6, 12 and 18 months. Rich micronutrient fortification had no significant benefit on the following: (a) number of developmental milestones achieved (rate ratio at 12 months = 1·00; 95 % CI 0·96, 1·05; P=0·81, adjusted for sex, socio-economic status and maternal education, with similar results at 15 and 18 months); (b) ages of walking unsupported (hazard ratio (HR) 1·04; 95 % CI 0·88, 1·24; P=0·63, adjusted for the above covariates) and of speaking three or four clear words (HR 1·01; 95 % CI 0·84, 1·20; P=0·94, adjusted for the above covariates); (c) mental development index (MDI) and psychomotor development index (PDI) of the Bayley scales (scores difference adjusted for baseline scores, age at the assessment, sex, socio-economic status, maternal education, language, age and HIV status: MDI 0·3 (95 % CI −0·5, 1·1), P=0·43; PDI −0·1 (95 % CI −0·9, 0·7), P=0·78). In conclusion, the results do not support the hypothesis that rich micronutrient fortification improves Zambian infants’ mental and motor development. PMID:21733297

    Women workers constitute one of the most vulnerable segments of the country's labour force. They often face different workplace health challenges than men do. They are engaged in a range of work that extends from heavy, monotonous, repetitive jobs, which are in many times experienced with low-paid and involves in long hours of work. Women's workplace health problems are frequently compounded by getting more of the same at home--the "double jeopardy" of domestic work. Specific issues to improve the workers motivation leading to enhancement of productivity and improving occupational health and safety were addressed. Context specific application of ergonomics principles were studied in the process of designing of work related equipment of local fruit processing units, as well as in tea industry, covering 180 subjects selected purposively. Ergonomic risk factors prevailed among the workers associates productivity and relevant health issues were quantified using QEC, RULA. NMQ was used to gather data on prevalence of CTDs among the workers. Pineapple peeling, tea leaves plucking were found highly labour intensive, done manually. Postures scores found were very high. WRMSDs were prevalent among the workers. Scope for ergonomic design intervention was observed to improve productivity and occupational health.

    Chili pepper (Capsicum annuum) is the most important and emblematic condiment in Mexican food. Serrano pepper is a variety of C. annuum that is traditionally cultivated in Mexico and commercialized in local markets. The aim of this study was to describe the 1 H NMR metabolomic profiling of the aqueous phase of serrano peppers harvested from two distinct regions, in the states of Veracruz and Oaxaca, Mexico. According to the current results, aspartate citrate, lactate, leucine and sucrose were found at higher amount in the serrano peppers from Veracruz. On the other hand, acetate, formate, fumarate, malonate, phosphocholine, pyruvate and succinate showed the highest abundance in this product from Oaxaca. These are the main metabolites that distinguish one group from the other. The spectrometric method reported presently is characterized by great simplicity, robustness and reproducibility. Thus, this technique can be used for establishing reliable metabolomic fingerprints of serrano peppers grown under different environmental conditions. Copyright © 2017 Elsevier Ltd.

    Full Text Available Soybeans are the most common source of isoflavones in human foods. The objectives of this study were to determine the effects of Thai soybean variety, planting date, physical seed quality, storage condition, planting location, and crop year on isoflavone content, as well as to analyze the relationship between seed viability and isoflavone content in soybean seeds grown in Thailand. Isoflavone content in Thai soybeans varied considerably depending on such factors as variety, physical seed quality, crop year, planting date (even in the same crop year, and planting location. Most varieties (except for Nakhon Sawan 1 and Sukhothai 1 had significantly higher isoflavone content when planted in early rather than in late dry season. Additionally, seed viability as well as long-term storage at 10∘C or at ambient condition seemed unlikely to affect isoflavone content in Thai soybean varieties. Isoflavone content in soybean seeds grown in Thailand depends on multiple genetic and environmental factors. Some varieties (Nakhon Sawan 1 and Sukhothai 1 exhibited moderately high isoflavone content regardless of sowing date. Soybeans with decreased seed viability still retained their isoflavone content.

    Food irradiation has a direct impact on society by reducing the occurrence of food-borne illness, decreasing food spoilage and waste, and facilitating global trade. Food irradiation is approved in 40 countries around the world to decontaminate food of disease and spoilage causing microorganisms, sterilize insect pests, and inhibit sprouting. A recent estimate suggests that 500,000 metric of food is currently irradiated worldwide, primarily to decontaminate spices. Since its first use in the 1960s the use of irradiation for food has grown slowly, but it remains the major technology of choice for certain applications. The largest growth sector in recent years has been phytosanitary irradiation of fruit to disinfest fruit intended for international shipment. For many countries which have established strict quarantine standards, irradiation offers as an effective alternative to chemical fumigants some of which are being phased out due to their effects on the ozone layer. Insects can be sterilized at very low dose levels, thus quality of fruit can be maintained. Irradiation is also highly effective in destroying microbial pathogens such as Salmonella spp., E. coli, and Listeria, hence its application for treatment of spices, herbs, dried vegetables, frozen seafood, poultry, and meat and its contribution to reducing foodborne illnesses. Unfortunately the use of irradiation for improving food safety has been under-exploited. This presentation will provide details on the use, benefits, opportunities, and challenges of food irradiation. (author)

  12. Ensuring food security

    Directory of Open Access Journals (Sweden)

    Valeriy Valentinovich Patsiorkovskiy

    2011-12-01

    Full Text Available This paper is devoted to the questions of further development of agricultural and food policy in the Russian Federation. The subject of in-depth consideration is the problem related to ensuring food safety. A critical review and analysis of major regulations in the field of food safety is made, including in the implementation of sanitary and epidemiological surveillance. The necessity of the expansion of measures to improve the statistics of food poisoning is grounded. The basic reasons for the spread of management practices of production and sale of food products that pose a threat to human life are revealed. The factors of unhindered penetration of local markets in the cities and the surrounding countrysides with counterfeiting, smuggling and production of global junk food manufacturers and consumer goods are defined. A systematic view is put on the problems of food production in the private farms, ways to limit direct access to the market of food and food raw materials, which production was not controlled and who have not passed state registration, are suggested. One of these problems is creation of independent industrial structures that link production and sales of small-scale sector goods.

    2007-01-01

    Food culture is most influenced by the locality of its origin, which will have been one of food acquisition and processing by various means. It is generally agreed, and is the basis of much United Nations, especially Food and Agriculture Organisation strategic development policy, that successful agriculture, horticulture and aquaculture along with fishing, underpin economically viable and healthy communities with their various food cultures. We also know that this must be in tandem with maternal literacy and operational health care systems. These elements are best represented on a regional basis. There is a growing consumer interest in knowing where one's food comes from as a measure of "food integrity". However, food production alone can be a precarious business and relate to a lesser or greater extent to local food culture and to trade, which may be complementary or at-odds with each other. Likewise, the local food culture may have its strengths and weaknesses as far as its ability to meet nutritional and health needs is concerned. Local food production may be restricted because of geographical or socio-economic conditions which preclude food diversity, although this may be compensated for by trade. Where food adequacy and diversity is compromised, and soils poor, various macronutrient, micronutrient (from animals and plants) and phytonutrient (nutritionally-advantageous food component from plants) deficiencies may be in evidence. These food system problems may be intertwined with food culture--for example, "rice-based and water-soluble vitamin poor"; "few animal-derived foods like meat, fish, eggs and milk with associated low calcium, vitamin D, Vitamin B12 and long chain n-3 fatty acid intakes"; "low fruit and vegetable intake with limited carotenoids and other phytonutrients".

  1. Loblolly pine grown under elevated CO2 affects early instar pine sawfly performance.

    Science.gov (United States)

    Williams, R S; Lincoln, D E; Thomas, R B

    1994-06-01

    Seedlings of loblolly pine Pinus taeda (L.), were grown in open-topped field chambers under three CO 2 regimes: ambient, 150 μl l -1 CO 2 above ambient, and 300 μl l -1 CO 2 above ambient. A fourth, non-chambered ambient treatment was included to assess chamber effects. Needles were used in 96 h feeding trials to determine the performance of young, second instar larvae of loblolly pine's principal leaf herbivore, red-headed pine sawfly, Neodiprion lecontei (Fitch). The relative consumption rate of larvae significantly increased on plants grown under elevated CO 2 , and needles grown in the highest CO 2 regime were consumed 21% more rapidly than needles grown in ambient CO 2 . Both the significant decline in leaf nitrogen content and the substantial increase in leaf starch content contributed to a significant increase in the starch:nitrogen ratio in plants grown in elevated CO 2 . Insect consumption rate was negatively related to leaf nitrogen content and positively related to the starch:nitrogen ratio. Of the four volatile leaf monoterpenes measured, only β-pinene exhibited a significant CO 2 effect and declined in plants grown in elevated CO 2 . Although consumption changed, the relative growth rates of larvae were not different among CO 2 treatments. Despite lower nitrogen consumption rates by larvae feeding on the plants grown in elevated CO 2 , nitrogen accumulation rates were the same for all treatments due to a significant increase in nitrogen utilization efficiency. The ability of this insect to respond at an early, potentially susceptible larval stage to poorer food quality and declining levels of a leaf monoterpene suggest that changes in needle quality within pines in future elevated-CO 2 atmospheres may not especially affect young insects and that tree-feeding sawflies may respond in a manner similar to herb-feeding lepidopterans.

    Adverse reactions to foods are commonly implicated in the causation of ill health. However, foreign antigens, including food proteins and commensal microbes encountered in the gastrointestinal tract, are usually well tolerated. True food allergies, implying immune-mediated adverse responses to food antigens, do exist, however, and are especially common in infants and young children. Allergic reactions to food manifest clinically in a variety of presentations involving the gastrointestinal, cutaneous, and respiratory systems and in generalized reactions such as anaphylaxis. Both IgE-mediated and non-IgE-mediated immune mechanisms are recognized. Important advances in the clinical features underlying specific food hypersensitivity disorders are reviewed.

    Full Text Available The assurance of food security at the individual level doesn’t implicitly provide for the one at family level as the concepts of hunger, malnutrition and food insecurity are the steps of the same process of access restricted to a sufficient supply of food. In order to achieve food security at the individual level the following is necessary: ensuring food availability (production, reserve stocks; redistribution of food availability within the country or out through international exchanges; effective access of the population to purchase food consumer goods, by ensuring its effective demand as required. Food security of families (FFS is required for assuring individual food security (IFS, but it is not sufficient because the food available may be unevenly distributed between family members. National food security (NFS corresponds to the possibilities that different countries have to ensure both FFS and IFS without sacrificing other important objectives. Under the name of GAS is defined the global food security which represents permanent access for the entire population of the globe to the necessary food for a healthy and active life.

    Full Text Available Olive oil consumption has grown substantially in recent years, due in part to the fact that olive oil is healthy. Much of the global olive oil production comes from the rural areas of Jaén in southern Spain. Surrounding this industry, services such as oleotourism are increasing. This paper aims to identify the key elements supporting the development of oleotourism. After a preliminary exploratory analysis of the existing data, a qualitative analysis was performed with actors directly involved in the industry in Jaén. The results helped us define the level of the stakeholders’ involvement and the sustainability, the opportunities, and the constraints affecting oleotourism in this area. The practical implications of this investigation can be useful for governing agencies, local firms, and the tourism industry in support of oleotourism development.

  17. Global climate change increases risk of crop yield losses and food insecurity in the tropical Andes.

    Tito, Richard; Vasconcelos, Heraldo L; Feeley, Kenneth J

    2018-02-01

    One of the greatest current challenges to human society is ensuring adequate food production and security for a rapidly growing population under changing climatic conditions. Climate change, and specifically rising temperatures, will alter the suitability of areas for specific crops and cultivation systems. In order to maintain yields, farmers may be forced to change cultivation practices, the timing of cultivation, or even the type of crops grown. Alternatively, farmers can change the location where crops are cultivated (e.g., to higher elevations) to track suitable climates (in which case the plants will have to grow in different soils), as cultivated plants will otherwise have to tolerate warmer temperatures and possibly face novel enemies. We simulated these two last possible scenarios (for temperature increases of 1.3°C and 2.6°C) in the Peruvian Andes through a field experiment in which several traditionally grown varieties of potato and maize were planted at different elevations (and thus temperatures) using either the local soil or soil translocated from higher elevations. Maize production declined by 21%-29% in response to new soil conditions. The production of maize and potatoes declined by >87% when plants were grown under warmer temperatures, mainly as a result of the greater incidence of novel pests. Crop quality and value also declined under simulated migration and warming scenarios. We estimated that local farmers may experience severe economic losses of up to 2,300 US$ ha -1  yr -1 . These findings reveal that climate change is a real and imminent threat to agriculture and that there is a pressing need to develop effective management strategies to reduce yield losses and prevent food insecurity. Importantly, such strategies should take into account the influences of non-climatic and/or biotic factors (e.g., novel pests) on plant development. © 2017 John Wiley & Sons Ltd.

    This study evaluated the impact of a pilot intervention promoting ethnic produce through classroom food demonstrations, tastings and home cooking activities among ethnically diverse elementary-school children ages 5-8 years old and their family members in Northern California. A total of 604 intervention students from four schools participated in classroom food demonstrations and tasting activities using seven food recipes. The control group included 600 students from two additional schools. Each recipe featured one vegetable from Latino, Hmong, or mainstream American cultures. Intervention students also received food kits containing ingredients to take home for each recipe. Mixed methods of quantitative student and parent pre-post surveys, parent feedback surveys, and qualitative focus groups were used to evaluate the intervention. Generalized estimating equations were used for survey data analysis. Qualitative data from parent focus groups were analyzed based on the principles of grounded theory. Both quantitative and qualitative results revealed that intervention students increased familiarity, preferences, and consumption of the featured vegetables and significantly increased their involvement in food preparation at home. Qualitative results showed that children were actively involved in food preparation at home. In addition, the intervention helped parents increase their appreciation for new foods and recipes. The results suggest that promoting locally grown ethnic produce to children is effective in increasing their consumption of a variety of vegetables and their involvement in food preparation at home.
