RESUMO

Purpose: Major changes were made to Canada's Food Guide (CFG) in 2019. This study aimed to understand the perceptions of older adults toward this newest version.Methods: Older adults were invited to participate via newsletters sent to older adults and retirees' organizations in the Province of Quebec. Participants completed an online survey about their baseline familiarity with the 2019 CFG using a 5-point Likert scale and took part in an individual semi-structured online interview, which explored their perceptions toward the 2019 CFG. A thematic qualitative analysis of the interview transcripts was performed.Results: Fifty-eight older adults (>65 years, 30 women, 28 men, including 19 consumers and 39 non-consumers of plant-based protein (PBP) foods) participated in the study. Older adults were mostly familiar with the 2019 CFG and had a positive perception of its features. They appreciated the design, proposed recipes, and healthy eating recommendations. Perceptions about the three food groups were mixed, mainly regarding the decreased emphasis on dairy products. Some appreciated that animal proteins were less prominent, while others raised issues on how to integrate PBP into their diet. Perceptions appeared to be influenced by sex and PBP consumption.Conclusion: Older adults in the Province of Quebec view most of the 2019 CFG recommendations positively. Our observations may be useful to dietitians and public health practitioners when developing strategies to improve adherence.

RESUMO

Purpose: This study aimed to assess the reliability and validity of an online approach to monitoring food affordability in Ontario using the updated Ontario Nutritious Food Basket (ONFB).Methods: The ONFB was priced online in 12 large multi-chain grocery stores to test intra-/inter-rater reliability using percent agreement and intra-class correlations (ICCs). Then, the ONFB was priced in-store and online in 28 stores to estimate food price differences using paired t-tests and Pearson's correlation for all (n =1708) and matched items (same product/brand and purchase unit) (n = 1134).Results: Intra-/inter-rater agreement was high (95.4%/81.6%; ICC = 0.972, F = 69.9, p < 0.001). On average, in-store prices were less than $0.02 lower than online prices. There were no significant differences between mean in-store and online prices for all items (t = 0.504 p = 0.614). The mean price was almost perfectly correlated between in-store and online (fully matched: R = 0.993 p < 0.001; all items: R = 0.967 p < 0.001). Online monthly ONFB estimates for a family of four were strongly correlated (R = 0.937 p < 0.001) with estimates calculated using in-store data.Conclusions: Online pricing is a reliable and valid approach to food costing in Ontario that contributes to modernizing the monitoring of food affordability in Canada and abroad.

RESUMO

Reducing ultra-processed foods (UPF) improves diet quality and may curb energy consumption. This study aimed to compare an intervention based on the reduction of UPF, according to the Dietary Guideline for the Brazilian Population (DGBP), with and without advice on energy intake. A parallel and randomised controlled trial was carried out with children with obesity from 7 to 12 years old. Both control (CG) and intervention groups (IG) participated monthly in 6 standardised educational activities based on the 10 steps of the DGBP. An individualised food plan was also provided to the IG. The rate of change for body mass index (BMI), waist circumference, body weight, and UPF consumption were investigated based on mixed-effect models. At the end of the study, the BMI declined in the IG (Δ = -0.27 kg/m2 ) compared to the CG (Δ = + 0.53 kg/m2 ) (p = .0002). Both groups showed a decline in grams of UPF until the fourth month and a gradual increase in the following months. Combining the qualitative approach of the DGBP with counselling on energy restriction through the diet plan proved to be effective in reducing childhood obesity. Clinical Trial Registration: This trial is registered at the Brazilian Registry of Clinical Trials (REBEC), under the RBR-3st5sn registry, available at http://www.ensaiosclinicos.gov.br/rg/RBR-3st5sn/. The datasets generated by the current study are not publicly available but are available from the corresponding author on reasonable request.

RESUMO

Serious games (i.e., digital games designed for educational purposes) can foster positive learning attitudes and are increasingly used as educational tools. Foodbot Factory is a serious game application (app) that helps children learn about healthy eating based on Canada's Food Guide principles and has demonstrated to increase nutrition knowledge among this group. This paper describes the process followed to expand Foodbot Factory's educational content and integrate immersive technologies and innovative features into the app. The revision process, which was guided by the Obesity-Related Behavioral Intervention Trials model, included the following phases: first, an interdisciplinary team of nutrition scientists, education experts, and computer scientists analyzed data from the original pilot study, recently published literature, and feedback from stakeholders to define areas to improve Foodbot Factory. The five original Foodbot Factory modules were evaluated by the team during weekly meetings, where the educational content, interactive features, and other elements that required updates (e.g., aesthetics and accessibility) were identified. Second, prototypes were created and refined until a final version of Foodbot Factory was approved. Nineteen children tested the updated Foodbot Factory and found it "easy to use" (89%) and "fun" (95%). The new version of Foodbot Factory contains 19 learning objectives, including 13 original and six new objectives. Interactive engagement features in the updated Foodbot Factory included augmented reality incorporated into two learning modules; new mini-games were created, including a memory game; an overhaul of the aesthetics; (e.g., new food images); and accessibility features were included to support users with cognitive and vision disabilities.

RESUMO

OBJECTIVES: Although better diet quality is inversely associated with mortality risk, the association between diet quality and mortality remains unclear in frail and non-frail older adults. Thus, we aimed to examine this association in older Japanese adults. DESIGN: A prospective cohort study. SETTING AND PARTICIPANTS: We used the data of 8,051 Japanese older adults aged ≥65 years in the Kyoto-Kameoka study. MESUREMENTS: Dietary intake was estimated using a validated food frequency questionnaire. Diet quality was evaluated by calculating the adherence scores to the Japanese Food Guide Spinning Top (range, 0 [worst] to 80 [best]), which were stratified into quartiles. Frailty status was assessed using the validated self-administered Kihon Checklist (KCL) and the Fried phenotype (FP) model. Survival data were collected between February 15, 2012 and November 30, 2016. Statistical analysis was performed using the multivariate Cox proportional hazard analysis and the spline model. RESULTS: During the median 4.75-year follow-up (36,552 person-years), we recorded 661 deaths. After adjusting for confounders, compared with the bottom adherence score quartile, the top quartile was associated with lower hazard ratio (HR) of mortality in frailty (HR, 0.73; 95% confidence interval [CI], 0.54-1.00) and non-frailty, as defined by the KCL (HR, 0.72; 95% CI, 0.52-1.01). In the spline model, regardless of frailty status defined by the KCL and FP model, adherence score showed a strongly dose-dependent inverse association with mortality up to approximately 55 points; however, no significant differences were observed thereafter. This association was similar to the results obtained in individuals with physical, cognitive, and depression as domains of KCL in the spline model. CONCLUSIONS: Our findings demonstrate an L-shaped association between diet quality and mortality in both frail and non-frail individuals. This study may provide important knowledge for improving poor diet quality in older individuals with frailty or domains of frailty.

RESUMO

INTRODUCTION: We analyzed the bio-food industry's corporate political activity (CPA) during the revisions of Canada's food guide between 2016 and 2019. METHODS: We undertook a content analysis of the websites of 11 bio-food industry organizations and of the briefs that 10 of them submitted to the Canadian House of Commons Standing Committee on Health, as part of this Committee's review of the food guide. Data were classified according to an existing conceptual framework. RESULTS: We identified 366 examples of CPA used by the bio-food industry during and immediately after the development of the food guide. Most of the industry actors opposed the guide's recommendations. The most common CPA strategies were information management (n = 197), used to create and disseminate information in industry's favour, and discursive strategies (n = 108), used to defend food products and promote the industry's position regarding the food guide. Influencing public policy (n = 40), by gaining indirect access to policy makers (e.g. through lobbying) and becoming active in government decision-making, as well as coalition management (n = 21), by establishing relationships with opinion leaders and health organizations, were also common strategies. CONCLUSION: Bio-food industry actors used many different CPA strategies during the revisions of the food guide. It is important to continue to document the bio-food industry's CPA to understand whether and how this is shaping public policy development in Canada and elsewhere.

RESUMO

For the first time since its introduction, the 2019 Canada's Food Guide (2019-CFG) highlighted specific guidance on eating practices, i.e., recommendations on where, when, why, and how to eat. The Canadian Eating Practices Screener / Questionnaire court canadien sur les pratiques alimentaires was developed to assess eating practices based on the 2019-CFG healthy eating recommendations. The objective of this cross-sectional study was to assess the construct validity and reliability of the Canadian Eating Practices Screener. From July to December 2021, adults (n = 154) aged 18-65 years completed a sociodemographic questionnaire and the screener. Construct validity was assessed by examining variability in screener scores, by comparing screener scores among subgroups with hypothesized differences in eating practices, and by examining the correlation between screener scores and fruit and vegetable intake. Reliability, i.e., internal consistency, was assessed by calculating Cronbach's coefficient alpha. Screener item scores were summed to provide a total score ranging from 21 to 105. The mean screener score was 76 (SD = 8.4; maximum, 105), ranging from 53 (1st percentile) to 92 (99th percentile). Differences in total scores in hypothesized directions were observed by age (p = 0.006), perceived income adequacy (p = 0.09), educational attainment (p = 0.002), and smoking status (p = 0.09), but not by gender or health literacy level. The correlation between screener scores and fruit and vegetable intake was 0.29 (p = 0.002). The Cronbach's coefficient alpha was 0.79, suggesting acceptable to high internal consistency. Study findings provide preliminary evidence of the screener's construct validity and reliability, supporting its use to assess eating practices based on the 2019-CFG healthy eating recommendations.

RESUMO

Little is known about Canadians' knowledge of the 2019 Canada's Food Guide (CFG) recommendations. Using cross-sectional survey data from the Guelph Family Health Study, our brief communication aimed to explore parents' knowledge of the 2019 CFG recommendations through descriptive statistics and content analysis. Among a sample of 122 parents, we found that parents had a general understanding of the 2019 CFG's recommendations but poor knowledge of specific details of the recommendations, such as the names of the three food groups and which foods contain unhealthy fats.

RESUMO

The present study aimed to evaluate factors associated with adherence to the Food Guide for the Brazilian Population (GAPB) among food service workers. A cross-sectional study was conducted with 421 employees from 43 food service establishments located in a capital of Brazil. Health and lifestyle data were collected, including the continuous use of medication, smoking, physical activity, and alcohol consumption. An instrument based on the GAPB was utilized, covering the domains of planning, household organization, eating habits, and food choices, according to GAPB recommendations. The findings revealed a direct association between the quality of life scores and the total GAPB adherence score (ß = 1.17; p < 0.001), as well as the domains of planning (ß = 0.53; p < 0.001), household organization (ß = 0.22; p = 0.001), and eating habits (ß = 0.38; p < 0.001). Adherence to the GAPB among food service workers was strongly linked to their perception of quality of life, in addition to other factors such as gender, age, education, type of work activity, and variables of lifestyle. Therefore, the eating practices of these employees need to be assessed comprehensively, and enhancing their quality of life can encourage proper and healthy eating.

RESUMO

Purpose: We conducted a pilot survey among young adults attending a suburban Canadian university to understand: (1) knowledge of the 2019 Canada's Food Guide (CFG); (2) self-reported food choices and eating habits; (3) perceived influence of the CFG on food choices and eating habits; and (4) suggestions to improve engagement with CFG.Methods: Students were recruited, through posts on social media platforms, to complete an online questionnaire between 7 March and 6 April 2020.Results: One-hundred and twenty-one (70% women) students responded. One-third (33%) of women and 8% of men reported consuming the recommended proportion of vegetables and fruits (i.e., 40%-60% of the plate) at their most recent meal (P = 0.001). Men were more likely to report overconsuming protein foods than women (58% vs 32%, P = 0.005). The perceived influence of the CFG on food choices and eating habits was low, with a mean score 2.2 ± 1.4 out of 7, with 7 indicating "highly influential." Over 92% of participants believed awareness of the CFG could be improved through social media platforms.Conclusions: Although half of the participants correctly answered all 8 questions that assessed knowledge of the CFG, there is an opportunity for dietitians and related health professionals to improve engagement with CFG.

RESUMO

BACKGROUND: Following Canada's food guide (CFG) recommendations should ensure adequate nutrient intakes. Older adults have increased needs for certain nutrients and nutrient density; the extent to which adherence to CFG recommendations can help reduce inadequate nutrient intakes is unknown. OBJECTIVES: We aimed to assess the relationship between adherence to CFG recommendations on healthy food choices and intake of key nutrients in adults 65 y and older from the Canadian Community Health Survey 2015 - Nutrition. METHODS: Secondary analysis of data from 4093 older adults of the Canadian Community Health Survey 2015 - Nutrition (mean age, 73.6 y, 54% females). Dietary intakes were measured using an interviewer-administered 24-h dietary recall, including 1 repeat in a subsample (42%). The National Cancer Institute multivariate method was used to estimate usual (i.e., long-term) dietary intakes. Adherence to CFG recommendations was measured using the Healthy Eating Food Index (HEFI)-2019 score. Simple linear and logistic regression models estimated the effect of increased HEFI-2019 score on usual nutrient intakes and the prevalence of inadequate nutrient intakes (i.e., below the estimated average requirements), respectively. RESULTS: Compared with the prevalence of inadequate intakes at median HEFI-2019 score (46.4/80 points), a higher HEFI-2019 (+11 points) was associated with reductions in the prevalence of inadequate intakes of magnesium, vitamin B6 and protein [-19.8% (95% confidence interval (CI): -30.8, -8.9), -12.7% (95% CI: -22.5, -3.0), and -4.7% (95% CI: -9.4, -0.1), respectively]. In contrast, data for higher HEFI-2019 scores were compatible with increased prevalence of inadequate intakes of folate, vitamin D, and calcium [4.0% (95% CI: -8.4, 16.3), 2.6% (95% CI: 1.1, 4.0), and 2.3% (95% CI: -3.0, 7.5), respectively]. CONCLUSIONS: Based on dietary intakes of Canadian older adults in 2015, increasing the degree of adherence to CFG recommendations on healthy food choices may reduce nutrient intake inadequacy for most key nutrients except folate, vitamin D, and calcium.

RESUMO

NOVELTY: The Canadian Food Intake Screener was developed to rapidly assess alignment of dietary intake with the Canada's Food Guide-2019 healthy food choices recommendations. Scoring is aligned with the Healthy Eating Food Index-2019 to the extent possible. Among a sample of adults, reasonable variation in screener scores was noted, mean screener scores differed between some subgroups with known differences in diet quality, and a moderate correlation between screener scores and total Healthy Eating Food Index-2019 scores based on repeat 24 h dietary recalls was observed. The Canadian Food Intake Screener has moderate construct validity for rapid assessment of overall alignment of adults' dietary intake with the Canada's Food Guide-2019 healthy food choices recommendations.

RESUMO

NOVELTY: The Canadian Food Intake Screener was developed to rapidly assess alignment of adults' dietary intake over the past month with the Food Guide's healthy food choices recommendations. The screener was developed and evaluated through an iterative process that included three rounds of cognitive interviews in each of English and French, along with ongoing feedback from external advisors and face and content validity testing with a separate panel of content experts. The 16-question screener is intended for use with adults, aged 18-65 years, with marginal and higher health literacy in research and surveillance contexts in which comprehensive dietary assessment is not possible.

RESUMO

Since the 2019 Canada Food Guide was released, there have been concerns raised over the cost of food, with an emphasis on the affordability of nutritious food. In this study, we evaluate the affordability of the 2019 Canada Food Guide in relation to the previous edition from 2007. As a result of the pandemic and other significant world events, many are feeling financial stress as prices in many areas of life rise, including housing, gas, and food. Our results show that it is more cost-effective, on average, for children and teens to follow the 2019 Canada Food Guide, but more expensive for adults, when compared to the 2007 edition.

RESUMO

Maternal underweight and inadequate gestational weight gain (GWG) are problems in Japan. However, increases in food intake aimed at weight gain alone are not sufficient for mother-child health. This study assessed diet quality based on the 3-day dietary records of pregnant women in an urban area of Japan in order to show the importance of evaluating diet quality, using the Nutrient-Rich Food Index 9.3 (NRF9.3), which is one metric based on nutrition profiling, and the Japanese Food Guide Spinning Top (JFGST). After excluding misreporters of energy intake, we stratified women (n = 91) by pre-pregnancy body mass index (BMI) and determined energy intake, diet quality status, and their relationship with GWG. Intakes of carbohydrate-containing staple foods, vegetable dishes, and fruit were insufficient regardless of BMI. Most of the underweight women with inadequate GWG had insufficient energy intake but high diet quality, as assessed by NRF9.3. In contrast, most women who consumed energy within the recommended range had low diet quality and gained weight at inappropriate levels. These results highlight the importance for pregnant Japanese women to maintain diet quality through a nutrient-dense diet, while simultaneously increasing energy intake after evaluation of their individual diet quality.

RESUMO

OBJECTIVE: The aim of this study was to investigate the involvement of Brazilian adolescents in home cooking, estimating its associations with sex and socioeconomic status. METHODS: This cross-sectional study involved a probabilistic sample of 14- to 19-y-olds enrolled in 29 public schools in the municipality of Juiz de Fora, MG, Southeast Brazil (n = 835). To assess involvement in home cooking, a 12-question questionnaire was used. The content was based on the Brazilian Food Guide, which encourages the acquisition, development, and sharing of culinary skills. Pearson's χ test and Poisson regression models were carried out, without and with adjustments. RESULTS: Most of the adolescents did not usually participate in meal planning (61%), and in the choice/purchase of food and culinary ingredients (67%). Boys were less likely to know how to cook "from scratch", positively self-evaluate their culinary skills, enjoy cooking, wish to learn more about cooking and meal preparation, and to participate frequently in the planning and preparation of meals. Belonging to a lower socioeconomic status represented a greater probability of preparing meals alone for the family. CONCLUSIONS: We verified an alarming prevalence of adolescents with behaviors unaligned with Brazilian Food Guide recommendations; that is, most of them, especially boys, were not involved in home cooking. Adolescence may present a window of opportunity for the development of culinary skills, resulting in long-term benefits for the population's diet quality. Furthermore, to change a historical pattern that overloads women's daily lives, it is necessary to encourage, from an early age, the presence of boys in the kitchen.

RESUMO

Purpose: This study investigated the potential influence of the 2019 Canada's Food Guide (CFG) on the eating environment and food provided in early learning and childcare centres across Canada.Methods: Directors of childcare centres were invited to complete an online survey about their awareness and adoption of the 2019 CFG and submit their menus for analysis.Results: Twenty-five directors completed the survey, and eighteen cycle menus were analyzed. Frequency and the types of foods offered in childcare centres were assessed. Ninety-two percent reported being aware of the changes in the food guide. Many challenges including the lack of support and resources, cost of food, and food reluctance could affect their ability to apply the changes, especially the incorporation of plant-based protein and the uncertainty around the amount of dairy products to provide. Menu analysis indicated frequency of offering items from the various food groups. Vegetables were mostly offered during lunchtime with an average offering rate of 4.83 ± 0.24 times per week.Conclusion: Representatives of early learning and childcare centres identified having difficulties in interpreting and applying the changes in the 2019 CFG. Dietitians have the knowledge and skills required to support childcare centres through training opportunities, workshops, toolkits, and advocacy.

RESUMO

Background: Obesity is one of the major public health problems worldwide and contributes to the onset of many diseases, especially the ones related to the metabolic syndrome. The new Dietary Guidelines for the Brazilian population bring a new food classification based on food processing and prioritizes the consumption of fresh or minimally processed foods. Aim: This study analyzed the effects of an educational intervention on obese women, on their weight loss, quality of life, components of the metabolic syndrome and pain. Methods: Randomized controlled pilot study, including 40 obese women, randomized into 2 groups: control group and intervention group. An educational intervention with 5 biweekly meetings of 90 min based on the Dietary Guidelines for the Brazilian population (2014) was carried out involving the intervention group. Parameters related to weight loss, quality of life (SF-36), pain (McGill), bioelectrical impedance analysis, cardiorespiratory fitness, and serum and clinical components of metabolic syndrome, as well as serum concentrations of cytokines were assessed. Results: Significantly decrease of body mass, waist and hip circumferences, basal metabolic rate, extracellular water, body capacitance, and body cell mass were observed in the intervention group after 3 months. Reduction of pain and improvement in quality of life and cardiorespiratory fitness were also observed in the intervention group. There were reductions in waist circumference and glycemia, components of metabolic syndrome. Conclusions: This study showed that the educational intervention can be associated with weight loss, increase in quality of life, reduction of pain, and better metabolic syndrome parameters in obese women.

RESUMO

BACKGROUND: Both poor maternal nutrition and toxic heavy metal exposure influence foetal growth and development. However, whether consumption of a variety of healthy foods modifies the association between prenatal heavy metal exposure and foetal growth is unknown. OBJECTIVE: We examined whether long-term maternal diet quality in periconception modifies the associations between maternal circulating concentrations of heavy metals and foetal growth. DESIGN: Data of 72,317 Japanese women who delivered singleton infants was extracted from the Japan Environment and Children's Study. Maternal diet over a 1-year before the first trimester of pregnancy was assessed using a validated food frequency questionnaire, and overall diet quality was determined using the balanced diet score based on the Japanese Food Guide Spinning Top. Maternal whole-blood concentrations of mercury (Hg), lead (Pb) and cadmium (Cd) were measured during the second/third trimester of pregnancy. Bayesian inference of multiple linear regression analysis was performed to evaluate the relationships between maternal diet quality and the blood concentrations of heavy metals; Bayesian logistic regression was used to analyse the risk of low birth weight (LBW; <2,500 g). RESULTS: After controlling for confounders, a high maternal balanced diet score was associated with low concentrations of blood Pb and Cd and high Hg. While all heavy metals assessed were positively associated with LBW risk, a higher maternal balanced diet score was negatively associated with LBW risk. A high-quality maternal diet attenuated the effect of Pb on LBW, an effect that was more marked at high blood Pb concentrations. CONCLUSION: A high-quality, 'well-balanced' diet prior to conception may reduce exposure to some heavy metals and mitigate the elevated risk of LBW associated with prenatal Pb exposure in Japanese mother-child pairs.

RESUMO

BACKGROUND: Nutrient dense food that supports health is a goal of food service in long-term care (LTC). The objective of this work was to characterize the "healthfulness" of foods in Canadian LTC and inflammatory potential of the LTC diet and how this varied by key covariates. Here, we define foods to have higher "healthfulness" if the are in accordance with the evidence-based 2019 Canada's Food Guide, or with comparatively lower inflammatory potential. METHODS: We conducted a secondary analysis of the Making the Most of Mealtimes dataset (32 LTC homes; four provinces). A novel computational algorithm categorized food items from 3-day weighed food records into 68 expert-informed categories and Canada's Food Guide (CFG) food groups. The dietary inflammatory potential of these food sources was assessed using the Dietary Inflammatory Index (DII). Comparisons were made by sex, diet texture, and nutritional status. RESULTS: Consumption patterns using expert-informed categories indicated no single protein or vegetable source was among the top 5 most commonly consumed foods. In terms of CFG's groups, protein food sources (i.e., foods with a high protein content) represented the highest proportion of daily calorie intake (33.4%; animal-based: 31.6%, plant-based: 1.8%), followed by other foods (31.3%) including juice (9.8%), grains (25.0%; refined: 15.0%, whole: 10.0%), and vegetables/fruits (10.3%; plain: 4.9%, with additions: 5.4%). The overall DII score (mean, IQR) was positive (0.93, 0.23 to 1.75) indicating foods consumed tend towards a pro-inflammatory response. DII was significantly associated with sex (female higher; p<0.0001), and diet (minced higher; p=0.036). CONCLUSIONS: "Healthfulness" of Canadian LTC menus may be enhanced by lowering inflammatory potential to support chronic disease management through further shifts from refined to whole grains, incorporating more plant-based proteins, and moving towards serving plain vegetables and fruits. However, there are multiple layers of complexities to consider when optimising foods aligned with the CFG, and shifting to foods with anti-inflammatory potential for enhanced health benefits, while balancing nutrition and ensuring sufficient food and fluid intake to prevent or treat malnutrition.
