RESUMO

BACKGROUND: A larger share of ultra-processed foods and drinks (UPF) in the diet is increasingly linked with poor diet quality, weight gain and elevated risk of diet-related chronic disease. This study used 2015 national-level data, the most recent available, to characterize the intake of UPF among Canadians and to examine changes since 2004. DATA AND METHODS: The 2004 and 2015 Canadian Community Health Surveys provided 24-hour dietary recall data for Canadians aged 2 or older. All food and drink items were classified according to type of food processing using the NOVA classification. The mean energy contribution of UPF (as a percentage of total daily energy intake) was compared across survey years for the overall population and for eight age-sex groups. The National Cancer Institute's methodology was used to assess the distribution of usual energy contributed by UPF. RESULTS: On average, UPF contributed 47.8% (95% CI: 47.3% to 48.3%) of total daily energy in 2004 and 45.7% (95% CI: 45.0% to 46.4%) in 2015 among the overall population, and more than half of total daily energy among children and adolescents. Both the mean energy contribution of UPF and their usual energy distribution shifted downward since 2004 for all age-sex groups, except among adults aged 55 or older. The energy contributions of soft drinks, fruit juices and fruit drinks declined, particularly among children and adolescents. Ultra-processed breads contributed more energy in 2015 for nearly all age-sex groups. DISCUSSION: As in 2004, the overall dietary share of UPF in Canada remained high in 2015, but intakes of some UPF, particularly beverages, declined. The energy contribution of UPF remained highest among children and adolescents, and increased among adults aged 55 or older.

RESUMO

The present commentary contains a clear and simple guide designed to identify ultra-processed foods. It responds to the growing interest in ultra-processed foods among policy makers, academic researchers, health professionals, journalists and consumers concerned to devise policies, investigate dietary patterns, advise people, prepare media coverage, and when buying food and checking labels in shops or at home. Ultra-processed foods are defined within the NOVA classification system, which groups foods according to the extent and purpose of industrial processing. Processes enabling the manufacture of ultra-processed foods include the fractioning of whole foods into substances, chemical modifications of these substances, assembly of unmodified and modified food substances, frequent use of cosmetic additives and sophisticated packaging. Processes and ingredients used to manufacture ultra-processed foods are designed to create highly profitable (low-cost ingredients, long shelf-life, emphatic branding), convenient (ready-to-consume), hyper-palatable products liable to displace all other NOVA food groups, notably unprocessed or minimally processed foods. A practical way to identify an ultra-processed product is to check to see if its list of ingredients contains at least one item characteristic of the NOVA ultra-processed food group, which is to say, either food substances never or rarely used in kitchens (such as high-fructose corn syrup, hydrogenated or interesterified oils, and hydrolysed proteins), or classes of additives designed to make the final product palatable or more appealing (such as flavours, flavour enhancers, colours, emulsifiers, emulsifying salts, sweeteners, thickeners, and anti-foaming, bulking, carbonating, foaming, gelling and glazing agents).

RESUMO

The aim of this study is to have an exploratory insight on how a sample of Brazilian adults classify food, attempting to identify the main factors involved in this process, and to compare these classifications to the NOVA food classification of the 2014 Brazilian dietary guidelines. An exploratory and qualitative approach was conducted with a selected sample of teachers, administrative technicians, and students (N = 24) from the Federal University of Grande Dourados, Brazil. First, using the pile sort method, participants were asked to freely classify 24 pictures of food (sourced from examples of the four food groups specified in NOVA) into food groups meaningful to them. Next, in semi-structured interviews, participants were asked to describe the food groups they created. The food groups created by participants were analyzed using non-metric multidimensional scaling followed by hierarchical cluster analysis, and the interviews were analyzed using content analysis. Participants had a mean age of 30 (±9.4) years. A total of 128 food groups were created by 24 participants (an average of five food groups per person); and a total of 55 non-mutually exclusive groups names were used by them to describe these food groups. Sixteen themes emerged from the content analysis. The most recurrent themes were food groups, nutrients, foods I consume, foods I do not consume, and food processing. Contrasting themes such as real food and junk foods, meals and ready-made foods, healthy foods and unhealthy foods were also noted. Six clusters emerged from the cluster analysis, each related to one or more themes. Overall, a striking similarity was observed between the ways the individuals classified food and the NOVA food classification.

RESUMO

OBJECTIVE: To evaluate the consumption of ultra-processed food and drink products and its association with the nutrient profile of the Colombian diet in 2005. MATERIALS AND METHODS: Food consumption based on 24-hour dietary records from 38 643 men and women was classified into four NOVA groups according to the extent and purpose of food processing. RESULTS: Ultra-processed food and drink products represented 15.9% of the total energy daily intake, compared to 63.3% from minimally processed food, 15.8% from processed culinary ingredients, and 4.9% from processed food. Non-ultra-processed food items had a healthier nutritional profile compared to ultra-processed items in terms of contribution to total calories from protein, carbohydrates, total fat, saturated fat, free sugar, fiber and energy density. CONCLUSIONS: Ultra-processed food products have a less healthy nutrient profile than non-ultra-processed ones. An increase in the consumption of these foods must be prevented within Colombia.


OBJETIVO: Evaluar el consumo de alimentos y bebidas ultraprocesadas y su asociación con el perfil nutricional dentro de la Encuesta Nacional de Nutrición de 2005 en Colombia. MATERIAL Y MÉTODOS: El consumo de alimentos basados en registros alimentarios de 24 horas de 38 643 individuos se clasificó en cuatro grupos de NOVA. RESULTADOS: Los productos de alimentos y bebidas ultraprocesados representaron 15.9% de la ingesta diaria total de energía, en comparación con 63.3% de los alimentos mínimamente procesados, 15.8% de los ingredientes culinarios procesados y 4.9% de los procesados. Los alimentos mínimamente procesados tenían un perfil nutricional más saludable en comparación con los artículos ultraprocesados en términos de contribución a las calorías totales, de proteínas, carbohidratos, grasa total, grasa saturada, azúcar libre, densidad de fibra y densidad de energía. CONCLUSIONES: Los alimentos ultraprocesados tienen un perfil nutricional menos saludable que los alimentos no procesados.

RESUMO

OBJECTIVE: The present paper aimed to identify the stakeholders, as well as their arguments and recommendations, in the debate on the application of a food processing-based classification system to the new Brazilian Food Guide. DESIGN: Qualitative approach; an analysis was made of documents resulting from the consultation conducted for the development of the new Brazilian Food Guide, which uses the NOVA classification for its dietary recommendations. A thematic matrix was constructed and the resulting themes represented the main points for discussion raised during the consultation. SETTING: Brazil. SUBJECTS: Actors from academia, government and associations/unions/professional bodies/organizations related to the area of nutrition and food security; non-profit institutions linked to consumer interests and civil society organizations; organizations, associations and food unions linked to the food industry; and individuals. RESULTS: Four themes were identified: (i) conflicting paradigms; (ii) different perceptions about the role and need of individuals; (iii) we want more from the new food guide; and (iv) a sustainable guide. CONCLUSIONS: There was extensive participation from different sectors of society. The debate generated by the consultation revealed two main conflicting opinions: a view aligned with the interests of the food industry and a view of healthy eating which serves the interests of the population. The first group was against the adoption of a food processing-based classification system in a public policy such as the new Brazilian Food Guide. The second group, although mostly agreeing with the new food guide, argued that it failed to address some important issues related to the food and nutrition agenda in Brazil.

RESUMO

It is now generally agreed that the impact of the current nature, purpose and extent of food processing on human well-being, health and disease needs to be better understood and explained, in order to improve public health. The special issue of Public Health Nutrition devoted to the concept of ultra-processing of food, and the NOVA classification of which ultra-processed foods are one category, is a great step forward in this work. Coincidentally, a polemical 'critical appraisal' of ultra-processing was recently published in another journal. Debate and discussion are an essential part of the scientific endeavour. In this commentary, we correct inaccurate statements made about NOVA in the 'appraisal,' rebut points raised, and discuss the larger issue of scientific responsibility for publishing opposing views on controversial topics.

RESUMO

OBJECTIVE: To assess associations between three diet quality indices and metabolic syndrome (MetS) in the Cree (Eeyouch) of northern Québec, Canada, as well as to evaluate their pertinence in this Indigenous context. DESIGN: The alternative-Healthy Eating Index 2010 (aHEI-2010), the Food Quality Score (FQS) and the contribution of ultra-processed products (UPP) to total daily dietary energy intake using the NOVA classification were calculated from 24 h food recalls. MetS was determined with the latest harmonized definition. Logistic regressions assessed the relationship between quintiles of dietary quality scores with MetS and its components. SETTING: Study sample from the 2005-2009 cross-sectional Nituuchischaayihititaau Aschii Environment-and-Health Study. SUBJECTS: Eeyouch (n 811) from seven James Bay communities (≥18 years old). RESULTS: MetS prevalence was 56·6 % with 95·4 % abdominal adiposity, 50·1 % elevated fasting plasma glucose, 43·4 % hypertension, 38·6 % elevated TAG and 44·5 % reduced HDL cholesterol. Comparing highest and lowest quintiles of scores, adjusted OR (95 % CI) of MetS was 0·70 (0·39, 1·08; P-trend=0·05) for aHEI-2010, 1·06 (0·63, 1·76; P-trend=0·87) for FQS and 1·90 (1·14, 3·17; P-trend=0·04) for the contribution of UPP to total daily dietary energy intake. CONCLUSIONS: Although diet quality indices have been associated with cardiometabolic risk, only the dietary intake of UPP was significantly associated with MetS in the Eeyouch. Indices tailored to the food environment of northern communities are essential to further understand the impact of diet quality in this context.

RESUMO

OBJECTIVE: To assess household availability of NOVA food groups in nineteen European countries and to analyse the association between availability of ultra-processed foods and prevalence of obesity. DESIGN: Ecological, cross-sectional study. SETTING: Europe. SUBJECTS: Estimates of ultra-processed foods calculated from national household budget surveys conducted between 1991 and 2008. Estimates of obesity prevalence obtained from national surveys undertaken near the budget survey time. RESULTS: Across the nineteen countries, median average household availability amounted to 33·9 % of total purchased dietary energy for unprocessed or minimally processed foods, 20·3 % for processed culinary ingredients, 19·6 % for processed foods and 26·4 % for ultra-processed foods. The average household availability of ultra-processed foods ranged from 10·2 % in Portugal and 13·4 % in Italy to 46·2 % in Germany and 50·4 % in the UK. A significant positive association was found between national household availability of ultra-processed foods and national prevalence of obesity among adults. After adjustment for national income, prevalence of physical inactivity, prevalence of smoking, measured or self-reported prevalence of obesity, and time lag between estimates on household food availability and obesity, each percentage point increase in the household availability of ultra-processed foods resulted in an increase of 0·25 percentage points in obesity prevalence. CONCLUSIONS: The study contributes to a growing literature showing that the consumption of ultra-processed foods is associated with an increased risk of diet-related non-communicable diseases. Its findings reinforce the need for public policies and actions that promote consumption of unprocessed or minimally processed foods and make ultra-processed foods less available and affordable.

RESUMO

OBJECTIVE: To quantify associations of the dietary share of ultra-processed foods (UPF) with the overall diet quality of First Nations peoples. DESIGN: A cross-sectional analysis of data from the First Nations Food, Nutrition and Environment Study, designed to contribute to knowledge gaps regarding the diet of First Nations peoples living on-reserve, south of the 60th parallel. A multistage sampling of communities was conducted. All foods from 24 h dietary recalls were categorized into NOVA categories and analyses were performed to evaluate the impact of UPF on diet quality. SETTING: Western and Central Canada. SUBJECTS: First Nations participants aged 19 years or older. RESULTS: The sample consisted of 3700 participants. UPF contributed 53·9 % of energy. Compared with the non-UPF fraction of the diet, the UPF fraction had 3·5 times less vitamin A, 2·4 times less K, 2·2 times less protein, 2·3 times more free sugars and 1·8 times more Na. As the contribution of UPF to energy increased so did the overall intakes of energy, carbohydrate, free sugar, saturated fat, Na, Ca and vitamin C, and Na:K; while protein, fibre, K, Fe and vitamin A decreased. Diets of individuals who ate traditional First Nations food (e.g. wild plants and game animals) on the day of the recall were lower in UPF. CONCLUSIONS: UPF were prevalent in First Nations diets. Efforts to curb UPF consumption and increase intake of traditional First Nations foods and other fresh or minimally processed foods would improve diet quality and health in First Nations peoples.

RESUMO

Given evident multiple threats to food systems and supplies, food security, human health and welfare, the living and physical world and the biosphere, the years 2016-2025 are now designated by the UN as the Decade of Nutrition, in support of the UN Sustainable Development Goals. For these initiatives to succeed, it is necessary to know which foods contribute to health and well-being, and which are unhealthy. The present commentary outlines the NOVA system of food classification based on the nature, extent and purpose of food processing. Evidence that NOVA effectively addresses the quality of diets and their impact on all forms of malnutrition, and also the sustainability of food systems, has now accumulated in a number of countries, as shown here. A singular feature of NOVA is its identification of ultra-processed food and drink products. These are not modified foods, but formulations mostly of cheap industrial sources of dietary energy and nutrients plus additives, using a series of processes (hence 'ultra-processed'). All together, they are energy-dense, high in unhealthy types of fat, refined starches, free sugars and salt, and poor sources of protein, dietary fibre and micronutrients. Ultra-processed products are made to be hyper-palatable and attractive, with long shelf-life, and able to be consumed anywhere, any time. Their formulation, presentation and marketing often promote overconsumption. Studies based on NOVA show that ultra-processed products now dominate the food supplies of various high-income countries and are increasingly pervasive in lower-middle- and upper-middle-income countries. The evidence so far shows that displacement of minimally processed foods and freshly prepared dishes and meals by ultra-processed products is associated with unhealthy dietary nutrient profiles and several diet-related non-communicable diseases. Ultra-processed products are also troublesome from social, cultural, economic, political and environmental points of view. We conclude that the ever-increasing production and consumption of these products is a world crisis, to be confronted, checked and reversed as part of the work of the UN Sustainable Development Goals and its Decade of Nutrition.

RESUMO

OBJECTIVE: To estimate the impact of reducing saturated fat, trans-fat, salt and added sugar from processed culinary ingredients and ultra-processed foods in the Brazilian diet on preventing cardiovascular deaths by 2030. DESIGN: A modelling study. SETTING: Data were obtained from the Brazilian Household Budget Survey 2008/2009. All food items purchased were categorized into food groups according to the NOVA classification. We estimated the energy and nutrient profile of foods then used the IMPACT Food Policy model to estimate the reduction in deaths from CVD up to 2030 in three scenarios. In Scenario A, we assumed that the intakes of saturated fat, trans-fat, salt and added sugar from ultra-processed foods and processed culinary ingredients were reduced by a quarter. In Scenario B, we assumed a reduction of 50 % of the same nutrients in ultra-processed foods and processed culinary ingredients. In Scenario C, we reduced the same nutrients in ultra-processed foods by 75 % and in processed culinary ingredients by 50 %. RESULTS: Approximately 390 400 CVD deaths might be expected in 2030 if current mortality patterns persist. Under Scenarios A, B and C, CVD mortality can be reduced by 5·5, 11·0 and 29·0 %, respectively. The main impact is on stroke with a reduction of approximately 6·0, 12·6 and 32·0 %, respectively. CONCLUSIONS: Substantial potential exists for reducing the CVD burden through overall improvements of the Brazilian diet. This might require reducing the penetration of ultra-processed foods by means of regulatory policies, as well as improving the access to and promotion of fresh and minimally processed foods.

RESUMO

We investigated the food types consumed by 3276 First Nations citizens from the First Nations Food Nutrition and Environment Study (FNFNES) living on-reserve in Canada. Data from 24-h dietary recalls were classified into NOVA categories: fresh or minimally processed foods (MPF), processed culinary ingredients, processed foods, and ultra-processed foods (UPF). Individuals were classified as traditional food (TF) eaters if they ate MPF of their First Nations culture. UPF accounted for 54.0% of energy intake; 23% of participants ate TF. Increasing age and household size, living in British Columbia and TF eating were associated with a lower intake of energy from UPF. Eating TF appeared to be protective against intake of UPF.

RESUMO

This study describes food consumption patterns in Canada according to the types of food processing using the Nova classification and investigates the association between consumption of ultra-processed foods and the nutrient profile of the diet. Dietary intakes of 33,694 individuals from the 2004 Canadian Community Health Survey aged 2 years and above were analyzed. Food and drinks were classified using Nova into unprocessed or minimally processed foods, processed culinary ingredients, processed foods and ultra-processed foods. Average consumption (total daily energy intake) and relative consumption (% of total energy intake) provided by each of the food groups were calculated. Consumption of ultra-processed foods according to sex, age, education, residential location and relative family revenue was assessed. Mean nutrient content of ultra-processed foods and non-ultra-processed foods were compared, and the average nutrient content of the overall diet across quintiles of dietary share of ultra-processed foods was measured. In 2004, 48% of calories consumed by Canadians came from ultra-processed foods. Consumption of such foods was high amongst all socioeconomic groups, and particularly in children and adolescents. As a group, ultra-processed foods were grossly nutritionally inferior to non-ultra-processed foods. After adjusting for covariates, a significant and positive relationship was found between the dietary share of ultra-processed foods and the content in carbohydrates, free sugars, total and saturated fats and energy density, while an inverse relationship was observed with the dietary content in protein, fiber, vitamins A, C, D, B6 and B12, niacin, thiamine, riboflavin, as well as zinc, iron, magnesium, calcium, phosphorus and potassium. Lowering the dietary share of ultra-processed foods and raising consumption of hand-made meals from unprocessed or minimally processed foods would substantially improve the diet quality of Canadian.

RESUMO

OBJECTIVES: The aim of this study was to evaluate the relationship between the consumption of ultra-processed foods and obesity indicators among Brazilian adults and adolescents. METHODS: We used cross-sectional data on 30,243 individuals aged ≥10 years from the 2008-2009 Brazilian Dietary Survey. Food consumption data were collected through 24-h food records. We classified food items according to characteristics of food processing. Ultra-processed foods were defined as formulations made by the food industry mostly from substances extracted from foods or obtained with the further processing of constituents of foods or through chemical synthesis, with little if any whole food. Examples included candies, cookies, sugar-sweetened beverages, and ready-to-eat dishes. Regression models were fitted to evaluate the association of the consumption of ultra-processed foods (% of energy intake) with body-mass-index, excess weight, and obesity status, controlling for socio-demographic characteristics, smoking, and physical activity. RESULTS: Ultra-processed foods represented 30% of the total energy intake. Those in the highest quintile of consumption of ultra-processed foods had significantly higher body-mass-index (0.94 kg/m(2); 95% CI: 0.42,1.47) and higher odds of being obese (OR=1.98; 95% CI: 1.26,3.12) and excess weight (OR=1.26; 95% CI: 0.95,1.69) compared with those in the lowest quintile of consumption. CONCLUSION: Our findings support the role of ultra-processed foods in the obesity epidemic in Brazil.

RESUMO

OBJECTIVE: To present and discuss the dietary guidelines issued by the Brazilian government in 2014. DESIGN: The present paper describes the aims of the guidelines, their shaping principles and the approach used in the development of recommendations. The main recommendations are outlined, their significance for the cultural, socio-economic and environmental aspects of sustainability is discussed, and their application to other countries is considered. SETTING: Brazil in the twenty-first century. SUBJECTS: All people in Brazil, now and in future. RESULTS: The food- and meal-based Brazilian Dietary Guidelines address dietary patterns as a whole and so are different from nutrient-based guidelines, even those with some recommendations on specific foods or food groups. The guidelines are based on explicit principles. They take mental and emotional well-being into account, as well as physical health and disease prevention. They identify diet as having cultural, socio-economic and environmental as well as biological and behavioural dimensions. They emphasize the benefits of dietary patterns based on a variety of natural or minimally processed foods, mostly plants, and freshly prepared meals eaten in company, for health, well-being and all relevant aspects of sustainability, as well as the multiple negative effects of ready-to-consume ultra-processed food and drink products. CONCLUSIONS: The guidelines' recommendations are designed to be sustainable personally, culturally, socially, economically and environmentally, and thus fit to face this century. They are for foods, meals and dietary patterns of types that are already established in Brazil, which can be adapted to suit the climate, terrain and customs of all countries.

RESUMO

OBJECTIVE: The present study describes the consumption patterns of sweetened food and drink products in a Catholic Middle Eastern Canadian community and examines its associations with physical activity, sedentary behaviours and BMI. DESIGN: A two-stage cross-sectional design was used. In Stage 1 (n 42), 24 h recalls enabled the identification of sweetened products. In Stage 2 (n 192), an FFQ was administered to measure the daily consumption of these products and to collect sociodemographic and behavioural data. Sweetened products were defined as processed culinary ingredients and ultra-processed products for which total sugar content exceeded 20% of total energy. SETTING: Three Catholic Middle Eastern churches located in Montreal, Canada. SUBJECTS: Normoglycaemic men and women (18-60 years old). RESULTS: Twenty-six sweetened products represented an average consumption of 75·4 g total sugars/d or 15·1% of daily energy intake (n 190, 56% women). Soft drinks, juices, sweetened coffee, chocolate, cookies, cakes and muffins were the main sources of consumption and mostly consumed between meals. Age (exp (ß) = 0·99; P < 0·01), physical activity (exp (ß) = 1·08; P < 0·01) and recreational computer use (exp (ß) = 1·17; P < 0·01) were independently associated with sweetened product consumption. The association between sweetened product consumption and physical activity was U-shaped. BMI was not significantly associated with sweetened product consumption but all participants regardless of BMI were above the WHO recommendation for free sugars. CONCLUSIONS: Being physically active and spending less time using a computer may favour a reduced consumption of sweetened products. Very active individuals may, however, overconsume such products.

RESUMO

PURPOSE: A classification of foods based on the nature, extent, and purpose of industrial food processing was used to assess changes in household food expenditures and dietary energy availability between 1938 and 2011 in Canada. METHODS: Food acquisitions from six household food budget surveys (1938/1939 , 1953, 1969, 1984, 2001, and 2011) were classified into unprocessed or minimally processed foods, processed culinary ingredients, and ready-to-consume processed or ultra-processed products. Contributions of each group to household food expenditures, and to dietary energy availability (kcal per capita) were calculated. RESULTS: During the period studied, household expenditures and dietary energy availability fell for both unprocessed or minimally processed foods and culinary ingredients, and rose for ready-to-consume products. The caloric share of foods fell from 34.3% to 25.6% and from 37% to 12.7% for culinary ingredients. The share of ready-to-consume products rose from 28.7% to 61.7%, and the increase was especially noteworthy for those that were ultra-processed. CONCLUSIONS: The most important factor that has driven changes in Canadian dietary patterns between 1938 and 2011 is the replacement of unprocessed or minimally processed foods and culinary ingredients used in the preparation of dishes and meals; these have been displaced by ready-to-consume ultra-processed products. Nutrition research and practice should incorporate information about food processing into dietary assessments.

RESUMO

BACKGROUND: Processed foodstuff may have a lower nutritional value than natural products. AIM: To analyze the impact of ready-to-consume products on diet quality of Chilean households. MATERIAL AND METHODS: A national representative sample of 10,096 households, based on the 6th Survey on Household Budget and Expenses (VI Encuesta de Presupuestos y Gastos Familiares, 2006-2007), was studied. Foodstuffs were classified as follows: 1) Unprocessed foods or minimally processed foods (G1); 2) Processed culinary ingredients (G2); and 3) Ready-to-consume products (G3). Calorie contribution and energy availability of each household food group, was calculated. The nutritional profile of the national food basket was calculated and compared with two simulated baskets (G3 vs G1+G2), based on international nutritional recommendations. RESULTS: Overall energy availability was of 1,885 kcal per capita/ day; 24% derived from unprocessed foods (G1), 21% from processed culinary ingredients (G2) and 55% from ready-to-consume products (G3), whose proportion increased along with income level. The 2007 national food basket contained an excess of total fat (34% vs 30%), free sugars (16% vs 10%), energy density (2.1 vs 1.3 kcal/gram) and a low amount of fiber (8.4 vs 12.5 g/1,000 kcal). The basket consisting in ready-to-consume products (G3) had a higher percentage of carbohydrates (61% vs 46%) than the basket consisting in unprocessed foods and ingredients (G1+G2). It also had a higher percentage of free sugars (17% vs 15%), less dietary fiber (7 vs. 10 g/1,000 kcal) and, above all, a higher energy density (2.6 vs 1.6 kcal/g). CONCLUSIONS: The Chilean dietary pattern, based on ready-to-consume products (G3), is affecting the nutritional quality of the diet.

RESUMO

BACKGROUND: Governments have a central role to play in creating a food environment that will enable people to have and maintain healthy eating practices. OBJECTIVES: This study analyzes public policies and government actions related to creating healthy food environments in Burkina Faso. METHODS: The Healthy Food Environment Policy Index tool used for this study has 2 components, 13 domains, and 56 indicators of good practice adapted to the Burkina Faso context. Official policy documents collected from data sources such as government and nongovernment websites, and through interviews with government and nongovernment resource persons, provided evidence of considerations of food environment in public policy documents in Burkina Faso. RESULTS: Policies documents show a lack of revision of old texts and administrative processes for new policies and government practices are very slow. Added to this is the absence of a regulatory document for some implemented actions. The analysis of the documents collected in relation to the indicators of Food-Epi tool shows that there is no evidence of consideration of food environments for the indicators concerning the regulation of nutrition and health claims, labeling, taxes on healthy and unhealthy foods, support systems for training for private structures on healthy diets, implementation of food guidelines, and food trade and investment. CONCLUSION: This study permits a review of public policies that take into account food environments through the various indicators and constitutes a starting point from which improvements can be made by the government.


Plain language titleOverview of Nutrition Policies, Taking Into Account All the Dimensions That Can Influence People's Food Choices Across Government, the Food Industry and SocietyPlain language summaryTo achieve healthy eating habits, governments need to be involved in creating a healthy food environment. This study analyzes public policies and government actions related to the creation of healthy food environments in Burkina Faso. The Healthy Food Environment Policy Index tool was used to carry out this study. Policy documents collected from data sources such as governmental and nongovernmental websites, and through interviews with governmental and nongovernmental resource persons, provided evidence of the consideration given to the food environment in Burkina Faso. Thus, policy documents show a lack of revision of older documents and a very slow administrative process. Added to this is the lack of regulatory documentation on concrete measures taken. An analysis of the documents collected according to the Food Epi-Tool indicators shows that food environments are not taken into account for indicators relating to nutrition and health claims, labeling and taxation of healthy and unhealthy foods, support systems for training private structures on healthy diets, implementation of food guidelines, and food trade and investment. In short, this research provides a starting point for evaluating and improving food-friendly public policies through a series of indicators.

RESUMO

BACKGROUND: Ultra-processed foods (UPF), as proposed by the Nova food classification system, are linked to the development of obesity and several non-communicable chronic diseases and deaths from all causes. The Nova-UPF screener developed in Brazil is a simple and quick tool to assess and monitor the consumption of these food products. The aim of this study was to adapt and validate, against the 24-hour dietary recall, this short food-based screener to assess UPF consumption in the Senegalese context. METHODS: The tool adaptation was undertaken using DELPHI methodology with national experts and data from a food market survey. Following the adaptation, sub-categories were renamed, restructured and new ones introduced. The validation study was conducted in the urban area of Dakar in a convenience sample of 301 adults, using as a reference the dietary share of UPF on the day prior to the survey, expressed as a percentage of total energy intake obtained via 24-hour recall. Association between the Nova-UPF score and the dietary share of UPF was evaluated using linear regression models. The Pabak index was used to assess the agreement in participants' classification according to quintiles of Nova-UPF score and quintiles of the dietary share of UPF. RESULTS: The results show a linear and positive association (p-value < 0.001) between intervals of the Nova-UPF score and the average dietary share of UPF. There was a near perfect agreement in the distribution of individuals according to score's quintiles and UPF dietary share quintiles (Pabak index = 0.84). CONCLUSION: The study concluded that the score provided by the Nova-UPF screener adapted to the Senegalese context is a valid estimate of UPF consumption.
