Many youth in Manitoba are not food secure. Newcomer youth may be more vulnerable to food insecurity. Further, it has been suggested that being food secure does not ensure a nutritionally adequate diet. This study examined survey data from 1,347 grade nine students to describe and compare food security by newcomer status. Survey data were also used to compare the dietary intakes, eating behaviors, and self-reported health of newcomer youth by food security status. Food security status between newcomer and non-newcomer youth was not significantly different, however, being food secure was not enough to have optimal nutritional health and well-being.

Many newcomers to Canada struggle with food insecurity and the health impacts of dietary acculturation. "Growing Roots" is a newcomer nutrition program designed through a community development approach to help immigrants and refugees adapt positively to the Canadian food environment. This qualitative action research project documented the development, implementation and impacts of the program in an inner city neighbourhood of Winnipeg, Manitoba, Canada. Data was collected through oral questionnaires and interviews. Impacts included: 1) Healthy adaptation to the Canadian foodscape; 2) Enhanced nutrition knowledge and behaviours; 3) Improvements to food security status; and 4) Enhanced social networks.

Homelessness, Aboriginal ethnicity, and nutritional vulnerability are key determinants of health. Substance abuse further compounds health risk. This study explored the nutritional vulnerability of homeless men, some of who were solvent-users, to assess nutrition-related chronic disease risk factors. Anthropometric data were used to calculate disease risk using body mass index. Diet was assessed using a 24-hr food recall and data were compared to Canada’s Food Guide recommendations. A significant proportion of participants had low intakes of vegetables and fruit and milk and alternatives. More than half of the participants met the intake recommendations for grain servings and meat and alternatives. Solvent-using participants consumed significantly higher intakes of vegetables and fruit, grain products, and other foods and beverages, than non-solvent using men. More than half of the participants were classified as overweight or obese. Healthy food consumption was influenced by lack of stable housing, reliance on charitable food, and substance abuse.

Background Canadian First Nation populations have experienced endemic and epidemic tuberculosis (TB) for decades. Vitamin D–mediated induction of the host defence peptide LL-37 is known to enhance control of pathogens such as Mycobacterium tuberculosis. Objective Evaluate associations between serum levels of 25-hydroxy vitamin D (25(OH)D) and LL-37, in adult Dene First Nation participants (N = 34) and assess correlations with single nucleotide polymorphisms (SNPs) in the vitamin D receptor (VDR) and vitamin D binding protein (VDBP). Design Venous blood was collected from all participants at baseline (winter and summer) and in conjunction with taking vitamin D supplements (1,000 IU/day) (winter and summer). Samples were analysed using ELISA for concentrations of vitamin D and LL-37, and SNPs in the VDR and VDBP regions were genotyped. Results Circulating levels of 25(OH)D were not altered by vitamin D supplementation, but LL-37 levels were significantly decreased. VDBP and VDR SNPs did not correlate with serum concentrations of 25(OH)D, but LL-37 levels significantly decreased in individuals with VDBP D432E T/G and T/T, and with VDR SNP Bsm1 T/T genotypes. Conclusions Our findings suggest that vitamin D supplementation may not be beneficial as an intervention to boost innate immune resistance to M. tuberculosis in the Dene population.

Current definitions of food insecurity center around the dominant themes of (1) individual and household food insecurity, stemming from a lack of access to resources needed to obtain adequate food; and (2) community food insecurity, which occurs when dominant food systems falls short in terms of social, economic, and environmental sustainability. These definitions do not sufficiently incorporate the concept ofnutrition securityor adequate nutritional status in terms of macro- and micronutrients, a state not achieved by most Canadians. We propose the Sustainable Livelihoods for Food and Nutrition Security Framework, which integrates food security and nutrition security to achieve public health nutrition goals.

Background. Increased awareness of the wide spectrum of activity of vitamin D has focused interest on its role in the health of Canada's Aboriginal peoples, who bear a high burden of both infectious and chronic disease. Cutaneous vitamin D synthesis is limited at northern latitudes, and the transition from nutrient-dense traditional to nutrient-poor market foods has left many Canadian Aboriginal populations food insecure and nutritionally vulnerable. Objective. The study was undertaken to determine the level of dietary vitamin D in a northern Canadian Aboriginal (Dené) community and to determine the primary food sources of vitamin D. Design. Cross-sectional study. Methods. Dietary vitamin D intakes of 46 adult Dené men and women were assessed using a food frequency questionnaire and compared across age, gender, season and body mass index. The adequacy of dietary vitamin D intake was assessed using the 2007 Adequate Intake (AI) and the 2011 Recommended Dietary Allowance (RDA) values for Dietary Reference Intake (DRI). Results. Mean daily vitamin D intake was 271.4 IU in winter and 298.3 IU in summer. Forty percent and 47.8% of participants met the vitamin D 1997 AI values in winter and summer, respectively; this dropped to 11.1 and 13.0% in winter and summer using 2011 RDA values. Supplements, milk, and local fish were positively associated with adequate vitamin D intake. Milk and local fish were the major dietary sources of vitamin D. Conclusions. Dietary intake of vitamin D in the study population was low. Only 2 food sources, fluid milk and fish, provided the majority of dietary vitamin D. Addressing low vitamin D intake in this population requires action aimed at food insecurity present in northern Aboriginal populations. [ABSTRACT FROM AUTHOR]
