Adherence to dietary advice targeting an EPA+DHA intake of 1g/d was examined over 1 year. Men and women (n 45) received dietary advice to increase EPA and DHA intakes from seafood, nutraceutical (fish oil) or functional food sources, while a fourth group received combined advice. Blood biomarkers and dietary intakes of EPA and DHA were evaluated at baseline and post-intervention at weeks 4, 8, 12, 24 and 52. Assessment by 3d diet records indicated that EPA+DHA intakes increased relative to baseline in weeks 4-52 following the seafood, nutraceutical and combined advice (advice groupxtime effect, P=0 center dot 03). The percentage of DHA in plasma and whole blood and the percentage of EPA in erythrocytes, plasma and whole blood were higher in weeks 4-52 when compared with the corresponding baseline measurement. In contrast, the percentage of DHA in erythrocytes increased to a maximum at week 12 and returned to baseline levels in weeks 24 and 52 (time effect, P<0 center dot 01). Measurement of the percentage of DHA in erythrocytes indicates that adherence was sustained during the first 12 weeks following the dietary advice, while other blood measurements of the percentage of EPA and DHA and dietary assessment suggest short-term increases in EPA+DHA intakes immediately before weeks 24 and 52. The percentage of DHA in erythrocytes characterises adherence to EPA and DHA intakes in long-term interventions.Canadian Foundation for Dietetic ResearchCanadian Institutes for Health ResearchNatural Sciences and Engineering Research Council of Canad

    This poster was presented at the Mosaic ’16 (Medical Library Association) Conference on May 17, 2016, Toronto, Ontario. Abstract: Methods: A grey literature search plan was developed to incorporate four different searching strategies: i) grey literature databases, ii) customized Google search engines, iii) targeted websites; and, iv) consultation with contact experts. These complementary strategies were used to minimize the risk of omitting relevant sources. Since abstracts are often unavailable in grey literature documents, items’ abstracts, executive summaries, or table of contents (whichever was available) were screened. Screening of publications’ full-text followed. Data were extracted on the organization, year published, who they were developed by, intended audience, goal/objectives of document, sources of evidence/resources cited, meals mentioned in the guidelines, and recommendations for program delivery. Results: The search strategies for identifying and screening publications for inclusion in the case study review was found to be manageable, comprehensive, and intuitive when applied in practice. The four search strategies of the grey literature search plan yielded 302 potentially relevant items for screening. Following the screening process, 15 publications that met all eligibility criteria remained and were included in the case study systematic review. Conclusions: This presentation demonstrates a feasible and seemingly robust method for applying systematic search strategies to identify web-based resources in the grey literature. The search strategy we developed and tested is amenable to adaptation to identify other types of grey literature from other disciplines and answering a wide range of research questions. This method should be further adapted and tested in future research syntheses

    <p>Abstract</p> <p>Background</p> <p>Complementary feeding is currently recommended after six months of age, when the nutrients in breast milk alone are no longer adequate to support growth. Few studies have examined macro- and micro-nutrient intakes from complementary foods (CF) only. Our purpose was to assess the sources and nutritional contribution of CF over the first year of life.</p> <p>Methods</p> <p>In July 2003, a cross-sectional survey was conducted on a nationally representative sample of mothers with infants aged three to 12 months. The survey was administered evenly across all regions of the country and included a four-day dietary record to assess infants' CF intakes in household (tablespoon) measures (breast milk and formula intakes excluded). Records from 2,663 infants were analyzed for nutrient and CF food intake according to 12 categories. Mean daily intakes for infants at each month of age from CF were pooled and compared to the Dietary Reference Intakes for the respective age range.</p> <p>Results</p> <p>At three months of age, 83% of infants were already consuming infant cereals. Fruits and vegetables were among the most common foods consumed by infants at all ages, while meats were least common at all ages except 12 months. Macro- and micro-nutrient intakes from CF generally increased with age. All mean nutrient intakes, except vitamin D and iron, met CF recommendations at seven to 12 months.</p> <p>Conclusions</p> <p>Complementary foods were introduced earlier than recommended. Although mean nutrient intakes from CF at six to 12 months appear to be adequate among Canadian infants, further attention to iron and vitamin D intakes and sources may be warranted.</p

    Insights into the Government’s Role in Food System Policy Making: Improving Access to Healthy, Local Food Alongside Other Priorities

    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

    Can dietary guidelines support the transformation of food systems to foster human and planetary health?

    There is substantial evidence of the need for efforts to drastically shift the food system to enable eating patterns consistent with human and planetary health. This will have implications for food production, processing, distribution and consumption. Eating patterns low in fruit, vegetables, whole grains, nuts and seeds and omega-3 fatty acids are contributing to morbidity and mortality around the world. This highlights the need for interventions to increase accessibility to foods that are currently under-consumed relative to recommendations. However, some of those foods are not produced in sufficient quantity, while others are being consumed at an environmentally unsustainable rate. Consequently, food-based dietary guidelines, traditionally aimed at providing evidence-based recommendations for healthy eating, appear to be evolving towards a holistic approach that embraces the complexity of eating patterns, the roles they play in society and the factors that influence them, as well as environmental sustainability considerations. The recent update to Canada’s Food Guide has taken such an approach, providing an opportunity to consider the extent to which such food-based dietary guidelines can support strategies to transform the food system.CGIAR Research Program on Agriculture for Nutrition and Health || Biotechnology and Biological Sciences Research Counci

    Giving voice to food insecurity in a remote indigenous community in subarctic Ontario, Canada: traditional ways, ways to cope, ways forward

    Get PDF
    BACKGROUND: Food insecurity is a serious public health issue for Aboriginal people (First Nations [FN], MĂ©tis, and Inuit) living in Canada. Food security challenges faced by FN people are unique, especially for those living in remote and isolated communities. Conceptualizations of food insecurity by FN people are poorly understood. The purpose of this study was to explore the perceptions of food insecurity by FN adults living in a remote, on-reserve community in northern Ontario known to have a high prevalence of moderate to severe food insecurity. METHODS: A trained community research assistant conducted semi-directed interviews, and one adult from each household in the community was invited to participate. Questions addressed traditional food, coping strategies, and suggestions to improve community food security and were informed by the literature and a community advisory committee. Thematic data analyses were carried out and followed an inductive, data-driven approach. RESULTS: Fifty-one individuals participated, representing 67% of eligible households. The thematic analysis revealed that food sharing, especially with family, was regarded as one of the most significant ways to adapt to food shortages. The majority of participants reported consuming traditional food (wild meats) and suggested that hunting, preserving and storing traditional food has remained very important. However, numerous barriers to traditional food acquisition were mentioned. Other coping strategies included dietary change, rationing and changing food purchasing patterns. In order to improve access to healthy foods, improving income and food affordability, building community capacity and engagement, and community-level initiatives were suggested. CONCLUSIONS: Findings point to the continued importance of traditional food acquisition and food sharing, as well as community solutions for food systems change. These data highlight that traditional and store-bought food are both part of the strategies and solutions participants suggested for coping with food insecurity. Public health policies to improve food security for FN populations are urgently needed

    Abstract Background Little is known about use of goal setting and tracking tools within online programs to support nutrition and physical activity behaviour change. In 2011, Dietitians of Canada added “My Goals,” a nutrition and physical activity behaviour goal setting and tracking tool to their free publicly available self-monitoring website (eaTracker® ( http://www.eaTracker.ca/ )). My Goals allows users to: a) set “ready-made” SMART (Specific, Measurable, Attainable, Realistic, Time-related) goals (choice of n = 87 goals from n = 13 categories) or “write your own” goals, and b) track progress using the “My Goals Tracker.” The purpose of this study was to characterize: a) My Goals user demographics, b) types of goals set, and c) My Goals Tracker use. Methods Anonymous data on all goals set using the My Goals feature from December 6/2012-April 28/2014 by users ≥19y from Ontario and Alberta, Canada were obtained. This dataset contained: anonymous self-reported user demographic data, user set goals, and My Goals Tracker use data. Write your own goals were categorized by topic and specificity. Data were summarized using descriptive statistics. Multivariate binary logistic regression was used to determine associations between user demographics and a) goal topic areas and b) My Goals Tracker use. Results Overall, n = 16,511 goal statements (75.4 % ready-made; 24.6 % write your own) set by n = 8,067 adult users 19-85y (83.3 % female; mean age 41.1 ± 15.0y, mean BMI 28.8 ± 7.6kg/m2) were included for analysis. Overall, 33.1 % of ready-made goals were from the “Managing your Weight” category. Of write your own goal entries, 42.3 % were solely distal goals (most related to weight management); 38.6 % addressed nutrition behaviour change (16.6 % had unspecific general eating goals); 18.1 % addressed physical activity behaviour change (47.3 % had goals without information on exercise amount and type). Many write your own goals were poor quality (e.g., non-specific (e.g., missing amounts)), and possibly unrealistic (e.g., no sugar). Few goals were tracked (<10 %). Demographic variables had statistically significant relations with goal topic areas and My Goals Tracker use. Conclusions eaTracker® users had high interest in goal setting and the My Goals feature, however, self-written goals were often poor quality and goal tracking was rare. Further research is needed to better support users

    « Très transformés, très emballés et très mauvais pour la santé... mais à faible risque » : exploration des liens entre sécurité des aliments et salubrité des aliments dans les collectivités

    No full text
    Introduction : L’insécurité alimentaire et les maladies d’origine alimentaire constituent des enjeux importants au Canada, et on peut considérer les mesures de santé publique prises pour les résoudre comme des facteurs qui façonnent l’environnement alimentaire. De nouvelles données probantes allant dans le sens d'une interrelation entre ces deux domaines, l’objectif de cette étude était d'explorer comment, en Colombie-Britannique (Canada), les efforts en matière de sécurité alimentaire des collectivités et les pratiques de salubrité des aliments (ainsi que les problèmes de santé de la population associés) peuvent se recouper, puis d’interpréter ces résultats pour concevoir et construire un environnement alimentaire plus sain. Méthodologie : Nous avons mené 14 entrevues auprès d’informateurs clés (praticiens des secteurs de la sécurité alimentaire des collectivités et de la salubrité des aliments en Colombie-Britannique) et procédé à une analyse descriptive qualitative pour trouver les points d’intersection entre ces deux secteurs. Résultats : Les participants ont fait état de quatre modalités de convergence entre les deux secteurs. Ils ont signalé comment les pratiques quotidiennes de leur secteur visant à promouvoir des aliments sûrs ou sains pouvaient être favorisées ou entravées par les activités de l’autre secteur, en partie car les politiques passées, disparates, ne tenaient pas compte des nombreux effets sur la santé en lien avec l'alimentation et car certains types de produits alimentaires, comme les fruits et légumes frais, peuvent être considérés à la fois comme risqués et bénéfiques. Enfin, ils ont souligné que les deux secteurs travaillent à l’atteinte d’un même but, soit celui d’améliorer la santé de la population, même si leur optique se révèle légèrement différente. Conclusion : La sécurité alimentaire et la salubrité des aliments sont connectées de plusieurs façons, ce qui a une incidence sur les spécificités de l'environnement alimentaire canadien et sur son amélioration. La collaboration entre les divers secteurs de la santé publique en lien avec l'alimentation est nécessaire pour concevoir de nouveaux programmes ou de nouvelles politiques visant à transformer les habitudes alimentaires des Canadiens

    Indigenous Community Perspectives of Food Security, Sustainable Food Systems and Strategies to Enhance Access to Local and Traditional Healthy Food for Partnering Williams Treaties First Nations (Ontario, Canada)

    No full text
    In partnership with communities of the Williams Treaties First Nations in southern Ontario (Canada), we describe an approach to work with communities, and highlight perspectives of food security and sustainability, including priorities and opportunities to revitalize local food systems as a pathway to food security and food sovereignty. The objectives of our project were: (1) to build a shared understanding of food security and sustainability; and (2) to document community priorities, challenges and opportunities to enhance local food access. Utilizing an Indigenous methodology, the conversational method, within the framework of community-based participatory research, formative work undertaken helped to conceptualize food security and sustainability from a community perspective and solidify interests within the four participating communities to inform community-led action planning. Knowledge generated from our project will inform development of initiatives, programs or projects that promote sustainable food systems. The community-based actions identified support a path towards holistic wellbeing and, ultimately, Indigenous peoples’ right to food security and food sovereignty
