RESUMO

Recommendations suggest limiting the intake of free sugar to under 10% or 5% of calories in order to reduce the risk of negative health outcomes. This study aimed to examine Canadian free sugar intake and model how intakes change following the implementation of a systematic reformulation of foods and beverages to be 20% lower in free sugar. Additionally, this study aimed to examine how calorie intake might be impacted by this reformulation scenario. Canadians' free sugar and calorie intakes were determined using free sugar and calorie data from the Food Label Information Program (FLIP) 2017, a Canadian branded food composition database, and applied to foods reported as being consumed in Canadian Community Health Survey-Nutrition (CCHS-Nutrition) 2015. A "counterfactual" scenario was modelled to examine changes in intake following the reformulation of foods to be 20% lower in free sugar. The overall mean free sugar intake was 12.1% of calories and was reduced to align with the intake recommendations at 10% of calories in the "counterfactual" scenario (p < 0.05). Calorie intake was reduced by 3.2% (60 calories) in the "counterfactual" scenario (p < 0.05). Although the overall average intake was aligned with the recommendations, many age/sex groups exceeded the recommended intake, even in the "counterfactual" scenario. The results demonstrate a need to reduce the intake of free sugar in Canada to align with dietary recommendations, potentially through reformulation. The results can be used to inform future program and policy decisions related to achieving the recommended intake levels of free sugar in Canada.

RESUMO

INTRODUCTION: Sex differences exist in children's obesity rates, dietary patterns and television viewing. Television continues to be a source of unhealthy food advertising exposure to children in Canada. Our objective was to examine sex differences in food advertising exposure in children aged 2 to 17 years across four Canadian English language markets. METHODS: We licensed 24-hour television advertising data from the company Numerator for January through December 2019, in four cities (Vancouver, Calgary, Montréal and Toronto) across Canada. Child food advertising exposure overall, by food category, television station, Health Canada's proposed nutrient profiling model, and marketing techniques were examined on the 10 most popular television stations among children and compared by sex. Advertising exposure was estimated using gross rating points, and sex differences were described using relative and absolute differences. RESULTS: Both male and female children were exposed to an elevated level of unhealthy food advertising and a plethora of marketing techniques across all four cities. Differences between sexes were evident between and within cities. Compared to females, males in Vancouver and Montréal viewed respectively 24.7% and 24.0% more unhealthy food ads/person/year and were exposed to 90.2 and 133.4 more calls to action, 93.3 and 97.8 more health appeals, and 88.4 and 81.0 more products that appeal to children. CONCLUSION: Television is a significant source of children's exposure to food advertising, with clear sex differences. Policy makers need to consider sex when developing food advertising restrictions and monitoring efforts.

RESUMO

Free sugars are a major source of calories in diets and contribute to the burden of many non-communicable diseases (NCDs). The World Health Organization (WHO) recommends reducing free sugars intake to less than 10% of total energy. This study aimed to estimate the number of diet-related NCD deaths which could be averted or delayed if Canadian adults were to reduce their calorie intake due to a systematic 20% reduction in the free sugars content in foods and beverages in Canada. We used the Preventable Risk Integrated ModEl (PRIME) to estimate the potential health impact. An estimated 6770 (95% UI 6184-7333) deaths due to diet-related NCDs could be averted or delayed, mostly from cardiovascular diseases (66.3%). This estimation would represent 7.5% of diet-related NCD deaths observed in 2019 in Canada. A 20% reduction in the free sugars content in foods and beverages would lead to a 3.2% reduction in calorie intake, yet an important number of diet-related NCD deaths could be averted or delayed through this strategy. Our findings can inform future policy decisions to support Canadians' free sugars intake reduction, such as proposing target levels for the free sugars content in key food categories.

RESUMO

BACKGROUND: Food and beverage promotion is a contributor to children's dietary behaviours, and ultimately, downstream health consequences. Broadcast television remains an important source of such advertising. The objective of this study was to examine and compare children and adolescent's exposure to food advertising on television in Canada over an entire year in a self-regulatory environment. METHODS: Television advertising data for 57 selected food and beverage categories were licensed from Numerator for 36 stations in Toronto, for 2019. The estimated average number of advertisements viewed by children aged 2-11 and adolescents aged 12-17 was determined overall, by food category, and by marketing technique. The healthfulness of advertisements was also assessed using Health Canada's Nutrient Profile Model. RESULTS: Overall in 2019, children viewed 2234.4 food ads/person/yr while adolescents viewed 1631.7 ads, exposure for both groups stemmed primarily from stations with general appeal, and both age groups were exposed to a range of powerful marketing techniques. Exposure to advertising for restaurants, snacks, breakfast food and candy and chocolate was high among both age groups and the healthfulness of most advertised products was considered poor. Adolescents were exposed to 36.4% more food products classified as unhealthy, had higher exposure to all marketing techniques examined, and were exposed to substantially more child-related marketing techniques compared to children. CONCLUSION: Children and adolescents were heavily exposed to food advertisements on television in 2019. Despite current self-regulatory policies, children's exposure to unhealthy food and beverages remains high. Differences in exposure to food advertisements by food category and healthfulness may suggest that adolescents are being disproportionately targeted by food companies as a result of self-regulatory marketing restrictions.

RESUMO

BACKGROUND: Food marketing can influence children's dietary behaviors. In Canada, Quebec banned commercial advertising to children under the age of 13 y in 1980, whereas advertising to children is self-regulated by industry in the rest of the country. OBJECTIVES: The objective of this study was to compare the extent and power of food and beverage advertising on television to children (age: 2-11 y) in two different policy environments (Ontario and Quebec). METHODS: Advertising data for 57 selected food and beverage categories were licensed from Numerator for Toronto and Montreal (English and French markets) from January to December 2019. The 10 most popular stations for children (age: 2-11 y) and a subset of child-appealing stations were examined. Exposure to food advertisements (ads) was based on gross rating points. A content analysis of food ads was conducted, and the healthfulness of ads was assessed using Health Canada's proposed nutrient profile model. Descriptive statistics were tabulated for the frequency of and exposure to ads. RESULTS: On average, children were exposed to 3.7 to 4.4 food and beverage ads per day, exposure to fast-food advertising was highest (670.7-550.6 ads per year), advertising techniques were used frequently, and the majority (>90%) of advertised products were classified as unhealthy. On the top 10 stations, French children in Montreal were most exposed to unhealthy food and beverage advertising (712.3 ads per year), although they were exposed to fewer child-appealing advertising techniques compared with those in other markets. On the child-appealing stations, French children in Montreal were least exposed to food and beverage advertising (43.6 ads per year per station) and child-appealing advertising techniques compared with the other groups. CONCLUSIONS: The Consumer Protection Act appears to positively impact exposure to child-appealing stations; yet, it does not sufficiently protect all children in Quebec and requires strengthening. Federal-level regulations restricting unhealthy advertising are needed to protect children across Canada.

RESUMO

BACKGROUND: The food industry advertises unhealthy foods intended for children which in turn fosters poor diets. This study characterized advertising expenditures on child-targeted products in Canada and compared these expenditures between Quebec, where commercial advertising to children under 13 is restricted, and the rest of Canada, where food advertising to children is self-regulated. METHODS: Advertising expenditures data for 2016 and 2019 for 57 select food categories and five media channels were licensed from Numerator. Products and brands targeted to children were identified based on their nature and the advertising techniques used to promote them. Advertising expenditures were classified as healthy/unhealthy using Health Canada's nutrient profile model. Expenditures per child capita aged 2-12 years were calculated and expenditures from 2016 were adjusted for inflation. Advertising expenditures were described by media, food category, year, and geographic region. RESULTS: Overall, $57.2 million CAD was spent advertising child-targeted products in Canada in 2019. Television accounted for 77% of expenditures followed by digital media (18%), and the food categories with the highest expenditures were candy/chocolate (30%) and restaurants (16%). The totality of expenditures (99.9%-100%) in both Quebec and the rest of Canada in 2016 and 2019 were considered 'unhealthy'. Across all media channels (excluding digital), advertising expenditures were 9% lower in 2019 versus 2016. Advertising expenditures per capita were 32% lower in Quebec ($9.40/capita) compared to the rest of the country ($13.91/capita). CONCLUSION: In Canada, millions are spent promoting child-targeted products considered inappropriate for advertising to children. While per capita advertising expenditures for these products are lower in Quebec compared to the rest of Canada, they remain high, suggesting that Quebec's commercial advertising restrictions directed to children are likely not sufficiently protecting them from unhealthy food advertising.

RESUMO

INTRODUCTION: More than 50% of Canadians report regularly eating foods prepared at restaurants. The literature shows poor nutritional quality of restaurant foods. No federal policy on improving the nutritional quality of restaurant food is available except for a provincial regulation that mandates Ontario chain restaurants to display the energy content of items on menus. There is limited information on the nutrition information reporting and nutritional quality of restaurant foods. This study aimed to examine the nutrition information reporting and nutritional quality of menu items of Canadian chain restaurants in 2020. METHODS: Nutrition information for menu items (n=18,760) was collected and analyzed from Canadian restaurants with ≥20 outlets nationally between 2020 and 2021. Menu items were categorized into 5 categories. Descriptive statistics were calculated for serving size, energy, and saturated fat, sodium, and sugar. Percentage daily values of energy and nutrient levels were calculated following the Canadian labeling guidelines. RESULTS: Of the 201 eligible chain restaurants, 141 (70%) provided some nutrition information, of which 70 (50%) voluntarily provided the complete nutrition information that is required on prepackaged foods. Overall, menu items were high per serving in energy (mean kcal=483; 95% CI=477, 489), saturated fat (mean=7.4 g; 95% CI=7.2, 7.5), sodium (mean=867 mg; 95% CI=853, 881), and total sugars (mean=17 g; 95% CI=17, 17), and all exceeded the recommended 15% percentage daily values threshold. CONCLUSIONS: Although most chain restaurants provided nutrition information, the lack of regulations regarding reporting format and provision of serving size and other nutrients challenges the assessment of the nutritional quality of menu items. Interventions to standardize nutrition information reporting and improve nutritional quality are needed in the restaurant sector.

RESUMO

This research estimated and characterized advertising expenditures on food products heavily advertised on youth-appealing television stations in Canada in 2019 overall, by media, by food category, and compared expenditures in two policy environments (Quebec and the rest of Canada, excluding the territories) and on "healthier" versus "less healthy" products. Advertising expenditure estimates for 57 selected food categories promoted on television, radio, out-of-home media, print media, and popular websites were licensed from Numerator. Sixty-one products or brands were identified as heavily advertised on youth-appealing stations and classified as "healthier" or "less healthy" based on a nutrient profile model proposed by Health Canada. Total expenditures and expenditures per adolescent capita were calculated. Approximately, $110.9 million was spent advertising food products heavily advertised to adolescents in Canada in 2019, with television accounting for 77% of total expenditures and fast food restaurants accounting for 51%. Most expenditures (77%; $80.6 million) were devoted to advertising "less healthy" products. In Quebec, advertising expenditures on examined products were 23% lower per capita ($45.15/capita) compared to the rest of Canada ($58.44/capita). Advertising expenditures in Quebec were lower for energy drinks (-47%; -$0.80/capita) and candy and chocolate (-41%; -$1.00/capita) and higher for yogurt (+85%; +$1.22/capita) and portable snacks (+25%; +$0.15/capita). Quebec's restriction of commercial advertising directed to children under 13 may explain lower per capita advertising expenditures on some "less healthy" foods heavily advertised to adolescents in Quebec. Nevertheless, this spending remains high in Quebec and nationally. Continued monitoring of these expenditures is warranted.

RESUMO

BACKGROUND: Food and beverage advertising has been identified as a powerful determinant of dietary intake and weight. Available evidence suggests that the preponderance of food and beverage advertising expenditures are devoted to the promotion of unhealthy products. The purpose of this study is to estimate food advertising expenditures in Canada in 2019 overall, by media and by food category, determine how much was spent on promoting healthier versus less healthy products and assess whether changes in these expenditures occurred between 2016 and 2019. METHODS: Estimates of net advertising expenditures for 57 selected food categories promoted on television, radio, out-of-home media, print media and popular websites, were licensed from Numerator. The nutrient content of promoted products or brands were collected, and related expenditures were then categorized as "healthy" or "unhealthy" according to a Nutrient Profile Model (NPM) proposed by Health Canada. Expenditures were described using frequencies and relative frequencies and percent changes in expenditures between 2016 and 2019 were computed. RESULTS: An estimated $628.6 million was spent on examined food and beverage advertising in Canada in 2019, with television accounting for 67.7%, followed by digital media (11.8%). In 2019, most spending (55.7%) was devoted to restaurants, followed by dairy and alternatives (11%), and $492.9 million (87.2% of classified spending) was spent advertising products and brands classified as "unhealthy". Fruit and vegetables and water accounted for only 2.1 and 0.8% of expenditures, respectively, in 2019. In 2019 compared to 2016, advertising expenditures decreased by 14.1% across all media (excluding digital media), with the largest decreases noted for print media (- 63.0%) and television (- 14.6%). Overall, expenditures increased the most in relative terms for fruit and vegetables (+ 19.5%) and miscellaneous products (+ 5%), while decreasing the most for water (- 55.6%) and beverages (- 47.5%). CONCLUSIONS: Despite a slight drop in national food and beverage advertising spending between 2016 and 2019, examined expenditures remain high, and most products or brands being advertised are unhealthy. Expenditures across all media should continue to be monitored to assess Canada's nutrition environment and track changes in food advertising over time.

RESUMO

BACKGROUND: Food companies shape Canada's food supply through voluntary actions and commitments concerning product (re)formulation; however, the extent that these initiatives translate into actual improvements in nutritional quality is unclear. This study examined changes in the nutritional quality of products offered by the top 22 packaged food and beverage companies in Canada from 2013 to 2017, in relation to the strength of their product (re) formulation actions and commitments. METHODS: The Food Company Reformulation (FCR) scoring tool was used to quantify the strength of companies' reported recent actions and commitments to reduce energy and nutrients of concern in their products, with higher scores signifying stronger voluntary actions/commitments. Nutritional information for products was sourced from the University of Toronto FLIP 2013 (n = 6490) and 2017 (n = 8277) databases (n = 4074 matched products). Changes in product healthfulness were assessed using the Health Star Rating (HSR) system (with higher HSRs denoting healthier products) and calories, sodium, saturated fat, trans fat, and total and free sugar levels per 100 g/mL. Generalized estimating equations examined changes in nutritional quality in relation to FCR scores. RESULTS: Overall, mean HSRs increased significantly for 5 companies' product portfolios and were reduced in 1 company's product portfolio. There were significant reductions in calories, sodium, saturated fat in 2 companies' portfolios and increases in 4, 3, and 8 companies' portfolios, respectively. Trans fats increased significantly in 2 companies' portfolios. Total and free sugars decreased significantly in 4 and 5 companies' portfolios, respectively, and increased in 1 company's portfolio. There was little change in the healthfulness of matched products. Higher FCR scores were not associated with greater increases in HSRs, or reductions in calories or nutrient amounts. FCR scores were negatively associated with HSRs and positively associated with total and free sugars. No relationship was observed between FCR scores and calories, sodium, saturated fat or trans fat. CONCLUSIONS: Reporting stronger voluntary product (re) formulation actions and commitments was not associated with greater improvements in the healthfulness of products offered by Canada's leading packaged food and beverage companies from 2013 to 2017, suggesting a need for stronger industry initiatives or mandatory government interventions to improve the healthfulness of the food supply.

RESUMO

In 2015, the Pan American Health Organization (PAHO) published sodium targets for packaged foods, which included two distinct levels: one "regional" and one "lower" target. Changes to the sodium content of the food supply in Latin American Countries (LAC) has not been evaluated. A repeated cross-sectional study used food label data from 2015 (n = 3859) and 2018 (n = 5312) to determine changes in the proportion of packaged foods meeting the PAHO sodium targets and the distribution in the sodium content of foods in four LAC (Argentina, Costa Rica, Paraguay, Peru). Foods were classified into the 18 food categories in the PAHO targets. The proportion of foods meeting the regional targets increased from 82.9% to 89.3% between 2015 and 2018 (p < 0.001). Overall, 44.4% of categories had significant decreases in mean sodium content. Categories with a higher proportion of foods meeting the regional and lower targets in 2018 compared to 2015 (p < 0.05) were breaded meat and poultry, wet and dry soups, snacks, cakes, bread products, flavored cookies and crackers, and dry pasta and noodles. While positive progress has been made in reducing the sodium content of foods in LAC, sodium intakes in the region remain high. More stringent targets are required to support sodium reduction in LAC.

RESUMO

BACKGROUND: Although packaged foods sold in retail stores must follow food labelling regulations, there are no e-grocery food labelling regulations to mandate and standardize the availability and presentation of product information. Therefore, the objective of the study was to evaluate the availability and quality of food labelling components in the Canadian e-grocery retail environment. METHODS: A sample of fresh and pre-packaged products was identified on eight leading grocery retail websites in Canada, to assess the availability and quality of food labelling components. RESULTS: Out of 555 product searches, all products were accompanied by product images with front-of-pack images more readily available (96.0%) than back-of-pack (12.4%) and other side panel images (3.1%). The following mandatory nutrition information was available for 61.1% of the products: nutrition facts table (68.8%), ingredient (73.9%), and allergen (53.8%) information. The majority of the nutrition information was available after scrolling down, clicking additionally on the description page, or viewing only as an image. Date markings were not available; packaging material information was available for 2.0% of the products. CONCLUSIONS: There was wide variability and inconsistencies in the presentation of food labelling components in the e-grocery retail environment, which can be barriers in enabling Canadians to make informed purchasing decisions.

RESUMO

OBJECTIVES: Traditional methods for creating food composition databases struggle to cope with the large number of products and the rapid pace of turnover in the food supply. This paper introduces Food Label Information Program (FLIP), a big data approach to the evaluation of the Canadian food supply and presents the latest methods used in the development of this database. METHODS: The Food Label Information Program (FLIP) is a database of Canadian food and beverage package labels by brand name. The latest iteration of the FLIP, FLIP 2020, was developed using website "scraping" to collect food labeling information (e.g., nutritional composition, price, product images, ingredients, brand, etc.) on all foods and beverages available on seven major Canadian e-grocery retailer websites between May 2020 and February 2021. RESULTS: The University of Toronto's Food Label Information Program (FLIP) 2020 was developed in three phases: Phase 1, database development and enhancements; Phase 2, data capture and management of food products and nutrition information; Phase 3, data processing and food categorizing. A total of 74,445 products available on websites of seven retailers and 2 location-specific duplicate retailers were collected for FLIP 2020. Of 57,006 food and beverage products available on seven retailers, nutritional composition data were available for about 60% of the products and ingredients were available for about 45%. Data for energy, protein, carbohydrate, fat, sugar, sodium and saturated fat were present for 54-65% of the products, while fiber information was available for 37%. Food products were classified under multiple categorization systems, including Health Canada's Table of Reference Amounts, Health Canada's sodium categories for guiding benchmark sodium levels, sugar-focused categories and categories specific to various global nutrient profiling models. CONCLUSIONS: FLIP is a powerful tool for evaluating and monitoring the Canadian food supply environment. The comprehensive sampling and granularity of collection provides power for revealing analyses of the relationship between nutritional quality and marketing of branded foods, timely observation of product reformulation and other changes to the Canadian food supply.

RESUMO

Engaging in facial emotion mimicry during social interactions encourages empathy and functions as a catalyst for interpersonal bonding. Decreased reflexive mirroring of facial expressions has been observed in individuals with different non-psychotic disorders, relative to healthy controls. Given reports of interpersonal relationship difficulties experienced by those who engage in non-suicidal self-injury (NSSI), it is of interest to explore facial emotion mimicry in individuals with a history of this behaviour (HNSSI). Among other things, this will enable us to better understand their emotion regulation and social interaction challenges. Surface facial electromyography (fEMG) was used to record the reflexive facial mimicry of 30 HNSSI and 30 controls while they passively observed a series of dynamic facial stimuli showing various facial expressions of emotion. Beginning with a neutral expression, the stimuli quickly morphed to one of 6 prototypic emotional expressions (anger, fear, surprise, disgust, happiness, or sadness). Mimicry was assessed by affixing surface electrodes to facial muscles known to exhibit a high degree of electrical activity in response to positive and negative emotions: the corrugator supercilii and the zygomaticus major. HNSSI participants, relative to controls, exhibited significantly less electrical activity in the corrugator muscle in response to viewing angry stimuli, and significantly less of an expected relaxation in muscle activity in response to viewing happy stimuli. Mirroring these results, greater endorsement of social influence as a motivator for engaging in NSSI was associated with less mimicry, and greater endorsement of emotion regulation as a motivator was associated with greater incongruent muscle response when viewing happy faces. These findings lend support to the theory that social interaction difficulties in HNSSI might be related to implicit violations of expected social rules exhibited through facial mimicry nonconformity.

RESUMO

INTRODUCTION: The nutritional quality of restaurant foods in Canada is not monitored by government and limited research has evaluated the nutrient content of these foods. Given the increasing proportion of foods consumed outside the home, this study aims to assess levels of nutrients of public health concern in Canadian fast-food and sit-down restaurant menu items. METHODS: Levels of calories, saturated fat, sodium, and sugar of 10,285 menu items from 90 national chain restaurants in Canada were assessed. Data were collected in 2016, extracted and analyzed between 2018 and 2020, and presented overall and by category. Levels in fast-food and sit-down restaurant establishments were compared. RESULTS: Overall mean levels of saturated fat, sodium, and sugar were high. Entrées contained on average 52% of the total daily value for sodium (1,256 mg/serving) and 45% of the daily value for saturated fat (8.9 g/serving). Beverages and desserts had high levels of total sugar (mean=44 g and 32 g/serving, respectively) but tended to be low in sodium. Sit-down restaurant items had significantly (p≤0.0001) higher levels of calories, saturated fat, and sodium overall, although fast-food restaurant items had higher average sugar levels because of the higher number of beverage and dessert items. CONCLUSIONS: Levels of nutrients of concern in Canadian menu items are excessive among most food categories. As the frequency of eating out in restaurants rises, government policies to promote reformulation and increase transparency of the nutritional content of these items are required to reduce their negative impact on public health.

RESUMO

OBJECTIVE: To quantify total sugar reformulation in Canadian prepackaged foods and beverages between 2013 and 2017 and identify changes in the nutritional composition of the foods and beverages reformulated to be lower in total sugar. DESIGN: Longitudinal examination of foods and beverages present in both 2013 and 2017 collections of the University of Toronto's Food Label Information Program database (n 6628 matched products). The proportion of products with changes in sugar levels was determined. Wilcoxon signed-rank test was used to examine changes in sugar levels overall for products lower or higher in sugar and changes in nutrient composition for products lower in sugar. SETTING: Largest grocery retailers by market share in Canada. PARTICIPANTS: Canadian prepackaged foods and beverages. RESULTS: The majority (76·6 %) of products had no change in total sugar content, 12·4 % were reformulated to be lower in sugar and 11·0 % were higher in sugar. A median sugar reduction of 19·0 % (1·6 g) was seen among products lower in sugar which was offset by a median 18·0 % (1·5 g) increase among products higher in sugar. Overall, median levels of energies and other nutrients stayed the same or decreased among products reformulated to be lower in sugar, the exception was for starch, which increased. CONCLUSIONS: Limited progress was made to reformulate foods and beverages to be lower in total sugar between 2013 and 2017. Results from this study identify areas in the food supply where attention may be needed to avoid unintended consequences of sugar-focused reformulation in terms of overall nutritional composition.

RESUMO

Individuals who engage in non-suicidal self-injury (NSSI) often report significant interpersonal difficulties, with studies lending support to the idea of impaired social interactions. Perceptual processing deficits of facial expressions have also been associated with interpersonal difficulties, yet little research has assessed how individuals with a history of NSSI (HNSSI) process facial emotions. This study used an ideal observer analysis to assess emotion processing capabilities of these individuals. A total of 30 HNSSI and 31 controls were presented with static images of various facial expressions (fear, anger, disgust, happiness, sadness, surprise) at three intensity levels (50%, 75% and 100% emotion expressivity). Recognition of emotions were measured by signal-proportion thresholds, efficiency scores, and unbiased hit rate. Error responses were also recorded to investigate errors biases made by each group. No significant differences between HNSSI and controls were found in signal-proportion thresholds or efficiency scores. Decreased accuracy of HNSSI participants for recognizing fearful expressions was observed. An increased likelihood of mistaking angry for happy expressions and a decreased likelihood of mistaking sad for surprised expressions were recorded for the HNSSI group compared to controls. These findings provide support to the literature reporting deficits in accurate emotion identification for those engaged in NSSI behaviours.

RESUMO

The association between the degree of processing and healthfulness of foods remains unclear. Most evidence of this relationship is based on dietary intake surveys rather than individual products and varies depending on the food processing classification system used. This study aimed to compare the nutritional quality of more- versus less-processed packaged foods and beverages in Canada, using a large, branded food database and two processing classification systems. Nutritional information for products (n = 17,269) was sourced from the University of Toronto FLIP 2017 database. Products were categorized using the NOVA and Poti et al. processing classification systems. Calories, sodium, saturated fat, total and free sugars, fibre and protein per 100 g (or mL) were examined by processing category using descriptive statistics and linear regression. Overall, the most-processed products under both systems were more likely to be lower in protein, and higher in total and free sugars, compared with less-processed foods (p < 0.05); the direction and strength of the association between other nutrients/components and level of processing were less consistent. These findings demonstrate that calorie- and nutrient-dense foods exist across different levels of processing, suggesting that food choices and dietary recommendations should be based primarily on energy or nutrient density rather than processing classification.

RESUMO

In order to verify if the full moon is associated with sleep and activity behaviors, we used a 12-country study providing 33,710 24-h accelerometer recordings of sleep and activity. The present observational, cross-sectional study included 5812 children ages 9-11 years from study sites that represented all inhabited continents and wide ranges of human development (Australia, Brazil, Canada, China, Colombia, Finland, India, Kenya, Portugal, South Africa, United Kingdom, and United States). Three moon phases were used in this analysis: full moon (±4 days; reference), half moon (±5-9 days), and new moon (±10-14 days) from nearest full moon. Nocturnal sleep duration, moderate-to-vigorous physical activity (MVPA), light-intensity physical activity (LPA), and total sedentary time (SED) were monitored over seven consecutive days using a waist-worn accelerometer worn 24 h a day. Only sleep duration was found to significantly differ between moon phases (~5 min/night shorter during full moon compared to new moon). Differences in MVPA, LPA, and SED between moon phases were negligible and non-significant (<2 min/day difference). There was no difference in the associations between study sites. In conclusion, sleep duration was 1% shorter at full moon compared to new moon, while activity behaviors were not significantly associated with the lunar cycle in this global sample of children. Whether this seemingly minimal difference is clinically meaningful is questionable.
