Qualitative analysis of front-of package labeling policy interactions between stakeholders and Health Canada

BackgroundFront-of-package labelling regulations proposed by Health Canada in their Healthy Eating Strategy (2016) were finally passed in 2022, but remain unimplemented. This study analyzed interactions that occurred between stakeholders and government related to this policy proposal to identify key themes and policy implications.MethodsA qualitative framework analysis was conducted on publicly available documents for stakeholder correspondences related to front-of-package that occurred between 2016 and 2019 in Health Canada’s Meetings and Correspondence on Healthy Eating database. Five sequential steps were applied: familiarization, identifying a thematic framework, indexing, charting, and mapping and interpretation. A complex systems (i.e., a dynamic system with multiple interconnecting components) lens was incorporated in the final step to deepen the analysis.ResultsHundred and seventy-three documents were included, the majority from industry stakeholders (n = 108, 62.4%). Three overarching themes were identified: industry trying to control the agenda and resist regulation; questioning the evidence supporting the policy and its impact on the agri-food industry; and dismissing the need and effectiveness of the policy. Incorporating a complex system lens found industry and non-industry stakeholders held markedly different perspectives on how cohesive the system defined by the front-of-package labelling policy was, and the policy impact on its stability. Economic and opportunity costs were the main trade-offs, and symbol misinterpretation considered an unintended consequence by industry. Finally, some stakeholders argued for wider policy scope incorporating more products, while others requested a narrower approach through exemptions.ConclusionInteractions with industry stakeholders on health food policy proposals require careful consideration, given it may suit their interests to generate delays and policy discordance. Explicitly setting out the principles of engagement and actively encouraging non-industry stakeholder representation provides a more balanced approach to policy consultation and development

The great leap from earth to heaven: The evolution of ballet and costume in England and France in the eighteenth century

The evolution of classical ballet from its accepted origins as one method of displaying status and aristocratic power in Renaissance Italy to its Romantic form, featuring professional ballerinas in white costumes dancing en pointe, took place largely during the long eighteenth century. This article discusses this transformation from the dual perspectives of choreography and costume by using the premise that these two vital elements in the presentation of ballet were co-dependent, each prompting the other to develop and evolve. Concentrating on Paris and London, it examines the relationship between court dress, fashion and theatre costume, and how this affected both the choreography and the style of dance throughout the long eighteenth century. © The Costume Society 2016

Copper Chaperone for Cu/Zn Superoxide Dismutase is a sensitive biomarker of mild copper deficiency induced by moderately high intakes of zinc

BACKGROUND: Small increases in zinc (Zn) consumption above recommended amounts have been shown to reduce copper (Cu) status in experimental animals and humans. Recently, we have reported that copper chaperone for Cu/Zn superoxide dismutase (CCS) protein level is increased in tissues of overtly Cu-deficient rats and proposed CCS as a novel biomarker of Cu status. METHODS: Weanling male Wistar rats were fed one of four diets normal in Cu and containing normal (30 mg Zn/kg diet) or moderately high (60, 120 or 240 mg Zn/kg diet) amounts of Zn for 5 weeks. To begin to examine the clinical relevance of CCS, we compared the sensitivity of CCS to mild Cu deficiency, induced by moderately high intakes of Zn, with conventional indices of Cu status. RESULTS: Liver and erythrocyte CCS expression was significantly (P < 0.05) increased in rats fed the Zn-60 and/or Zn-120 diet compared to rats fed normal levels of Zn (Zn-30). Erythrocyte CCS expression was the most sensitive measure of reduced Cu status and was able to detect a decrease in Cu nutriture in rats fed only twice the recommended amount of Zn. Liver, erythrocyte and white blood cell CCS expression showed a significant (P < 0.05) inverse correlation with plasma and liver Cu concentrations and caeruloplasmin activity. Unexpectedly, rats fed the highest level of Zn (Zn-240) showed overall better Cu status than rats fed a lower level of elevated Zn (Zn-120). Improved Cu status in these rats correlated with increased duodenal mRNA expression of several Zn-trafficking proteins (i.e. MT-1, ZnT-1, ZnT-2 and ZnT-4). CONCLUSION: Collectively, these data show that CCS is a sensitive measure of Zn-induced mild Cu deficiency and demonstrate a dose-dependent biphasic response for reduced Cu status by moderately high intakes of Zn

Sparing effects of selenium and ascorbic acid on vitamin C and E in guinea pig tissues

BACKGROUND: Selenium (Se), vitamin C and vitamin E function as antioxidants within the body. In this study, we investigated the effects of reduced dietary Se and L-ascorbic acid (AA) on vitamin C and α-tocopherol (AT) status in guinea pig tissues. METHODS: Male Hartley guinea pigs were orally dosed with a marginal amount of AA and fed a diet deficient (Se-D/MC), marginal (Se-M/MC) or normal (Se-N/MC) in Se. An additional diet group (Se-N/NC) was fed normal Se and dosed with a normal amount of AA. Guinea pigs were killed after 5 or 12 weeks on the experimental diets at 24 and 48 hours post AA dosing. RESULTS: Liver Se-dependent glutathione peroxidase activity was decreased (P < 0.05) in guinea pigs fed Se or AA restricted diets. Plasma total glutathione concentrations were unaffected (P > 0.05) by reduction in dietary Se or AA. All tissues examined showed a decrease (P < 0.05) in AA content in Se-N/MC compared to Se-N/NC guinea pigs. Kidney, testis, muscle and spleen showed a decreasing trend (P < 0.05) in AA content with decreasing Se in the diet. Dehydroascorbic acid concentrations were decreased (P < 0.05) in several tissues with reduction in dietary Se (heart and spleen) or AA (liver, heart, kidney, muscle and spleen). At week 12, combined dietary restriction of Se and AA decreased AT concentrations in most tissues. In addition, restriction of Se (liver, heart and spleen) and AA (liver, kidney and spleen) separately also reduced AT in tissues. CONCLUSION: Together, these data demonstrate sparing effects of Se and AA on vitamin C and AT in guinea pig tissues

Role of dietary selenium as an antioxidant during carcinogenesis

Experiments were conducted to examine the role of dietary selenium (Se) and changes in antioxidant capacity during DMBA-induced mammary carcinogenesis. Weanling rats were fed graded amounts of Se in an AIN-76 diet, modified to approximate the amount and type of dietary fat consumed in Canada. Animals fed 3-4 ppm Se had a reduced tumor incidence but there was evidence of chronic Se toxicity. Low Se did not elevate tumor incidence. Thus, supplemental dietary Se did not offer any protection in reducing the incidence of cancer when rats were fed a diet representative of North American intakes of fat. Blood GSHPx activity was elevated in rats that remained free of tumors (NT group) compared to animals that would eventually develop tumors (WT group). SOD activity was reduced in WT and NT rats, but appeared to be related to carcinogen administration. These differences were observed before tumor development and over a wide range of Se intakes. WT rats excreted more $sp{75}$Se compared to both control and NT rats. These changes, however, were not reflected in elevated lipid peroxidation. Thus, one of the protective mechanisms during carcinogenesis may be the capacity of the animal to elevate GSHPx activity

The Time for an Updated Canadian Food Guide Has Arrived

Canada has published food guides since 1942 and the latest version, “Eating Well with Canada’s Food Guide” (EWCFG) was released in 2007. The EWCFG is largely based on meeting nutrient requirements while we are now in need of a food guide with strong guidance on the role of diet in preventing chronic diseases. This article systematically analyses the process and assumptions behind the EWCFG and presents suggestions for needed revisions to the next food guide.The accepted manuscript in pdf format is listed with the files at the bottom of this page.

Child-appealing packaged food and beverage products in Canada-Prevalence, power, and nutritional quality.

BackgroundChildren are frequently exposed to marketing on food packaging. This study evaluated the presence, type and power of child-appealing marketing and compared the nutritional quality of child-appealing vs. non-child-appealing Canadian packaged foods and examined the relationship between nutrient composition and marketing power.MethodsChild-relevant packaged foods (n = 5,850) were sampled from the Food Label Information Program 2017 database. The presence and power (# of techniques displayed) of child-appealing marketing were identified. Fisher's Exact test compared the proportion of products exceeding Health Canada's nutrient thresholds for advertising restrictions and Mann Whitney U tests compared nutrient composition between products with child- /non-child-appealing packaging. Pearson's correlation analyzed the relationship between nutrient composition and marketing power.Results13% (746/5850) of products displayed child-appealing marketing; the techniques used, and the power of the marketing varied ([Formula: see text] 2.2 techniques; range: 0-11). More products with child-appealing packaging than with non-child appealing packaging exceeded Health Canada's thresholds (98% vs. 94%; p ConclusionsUnhealthy products with powerful child-appealing marketing displayed on package are prevalent in the food supply. Implementing marketing restrictions that protect children should be a priority

The effectiveness of voluntary policies and commitments in restricting unhealthy food marketing to Canadian children on food company websites

Marketing unhealthy foods and beverages to children (M2K) fosters poor dietary patterns, increasing obesity and non-communicable disease risk. Federal restrictions on M2K have been under development in Canada since 2016; however, at present, M2K is mostly self-regulated by food companies. This study aimed to compare M2K on Canadian websites of food companies with and without voluntary policies or commitments in this area. A systematic content analysis of company websites was conducted in Spring/Summer 2017 for major packaged food (n=16), beverage (n=12) and restaurant chain (n=13) companies in Canada. M2K policies were sourced from company websites and published corporate documents. Sixteen companies (43%) reported national and/or global M2K policies, while 21 companies (57%) had no published policies. Companiesâ Canadian websites (n=154) were scanned for child-directed products and marketing; type and frequency of marketing techniques were recorded. Child-directed marketing appeared on 19 websites of 12 companies (32%), including 9 companies with M2K policies. Websites featured products with unconventional flavours, colours, shapes or child-oriented packaging, and used promotional characters, contests, games, activities or lettering and graphics appealing to children. The nutritional quality of products marketed to children was evaluated using a nutrient profile model developed by Health Canada for proposed M2K regulations. Of the 217 products marketed to children, 97% exceeded Health Canadaâ s proposed 5% DV threshold for saturated fat, sodium and/or sugars, 73% of which were products from 9 companies with policies. These findings highlight the limitations of self-regulation in restricting M2K on food company websites, reinforcing the need for government regulations.The accepted manuscript in pdf format is listed with the files at the bottom of this page.

Canadian adaptation of the Newest Vital Sign©, a health literacy assessment tool

Objective: The Newest Vital Sign (c) (NVS) was developed in the USA to measure patient health literacy in clinical settings. We adapted the NVS for use in Canada, in English and French, and created a computerized version. Our objective was to evaluate the reliability of the Canadian NVS as a self-administered computerized tool. Design: We used a randomized crossover design with a washout period of 3-4 weeks to compare health literacy scores obtained using the computerized version with scores obtained using the standard interviewer-administered NVS. ANOVA models and McNemar's tests assessed differences in outcomes assessed with each version of the NVS and order effects of the testing. Setting: Participants were recruited from multicultural catchment areas in Ontario and Nova Scotia. Subjects: English- and French-speaking adults aged 18 years or older. Results: A total of 180 (81%) of the 222 adults (112 English/110 French) initially recruited completed both the interviewer-NVS and computer-NVS. Scores for those who completed both assessments ranged from 0 to 6 with a mean of 3-63 (SD 2.41) for the computerized NVS and 3.41 (SD 2.21) for the interview-administered NVS. Few (n 18; seven English, eleven French) participants' health literacy assessments differed between the two versions. Conclusions: Overall, the computerized Canadian NVS performed as well as the interviewer-administered version for assessing health literacy levels of English- and French-speaking participants. This Canadian adaptation of the NVS provides Canadian researchers and public health practitioners with an easily administered health literacy assessment tool that can be used to address the needs of Canadians across health literacy levels and ultimately improve health outcomes.Canadian Institutes of Health Research (CIHR) [201403MOP 137037]12 month embargo; published online: 25 April 2018This item from the UA Faculty Publications collection is made available by the University of Arizona with support from the University of Arizona Libraries.
