Infants' Dietary Pattern Characterized by Ultraprocessed Foods Is Associated With Rapid Weight Gain and Overweight/Obesity Risk: National Health and Nutrition Examination Survey 2009-2018.

BACKGROUND: Global trends toward childhood obesity have been associated with several factors, including suboptimal infant feeding practices, the increasing availability of ultraprocessed foods in the world's food supply, and the corresponding changes in children's dietary patterns. OBJECTIVE: To describe infants' dietary patterns and assess their associations with weight status outcomes in a nationally representative sample of US infants. DESIGN: Cross-sectional analyses were performed on data collected from infants participating in the 2009-2018 National Health and Nutrition Examination Survey. PARTICIPANTS/SETTING: Participants included 744 infants aged 6 to 12 months who had data from at least 1 day of valid 24-hour dietary recall data. MAIN OUTCOME MEASURES: Rapid weight gain and overweight/obesity risk. STATISTICAL ANALYSES PERFORMED: Principal component analysis was used to identify dietary patterns considering the energy intake of 39 Nova food subgroups (expressed in calories per day), including breast milk. Associations were evaluated using logistic regression adjusted for potential confounders. RESULTS: A total of 42% infants experienced rapid weight gain, and 33% were at risk of overweight/obesity. Most infants (65.5%) were started on solid foods early. Three main dietary patterns were derived. The first pattern, labeled Natural or Minimally Processed Foods, had positive loadings for a variety of natural or minimally processed foods, some processed culinary ingredients, and a few processed and ultraprocessed foods. The second pattern, labeled Infant Formula, had high negative loading for breast milk, and high positive loading for infant formula and breakfast cereal. The third pattern, labeled Ultraprocessed Foods, had negative loadings for natural or minimally processed foods and processed culinary ingredients, positive loadings for other processed foods and for a variety of ultraprocessed foods, and negative loading for infant formula. Infants who adhere to the Ultraprocessed Foods dietary pattern were more likely to present rapid weight gain (adjusted odds ratio 1.3, 95% CI 1.1 to 1.5) and overweight/obesity risk (adjusted odds ratio 1.2, 95% CI 1.0 to 1.4). CONCLUSIONS: Higher adherence to a dietary pattern characterized by ultraprocessed foods was associated with a greater likelihood of both rapid weight gain and overweight/obesity risk early in life. Promoting breastfeeding and increasing consumption of unprocessed/minimally processed foods during early infancy while restricting ultraprocessed foods are key components to reducing the growing burden of childhood obesity.

The environmental impact of beef and ultra-processed food consumption in Brazil.

OBJECTIVE: This study evaluated the independent and combined environmental impacts of the consumption of beef and ultra-processed foods in Brazil. DESIGN: Cross-sectional study. SETTING: Brazil. PARTICIPANTS: We used food purchases data from a national household budget survey conducted between July 2017 and July 2018, representing all Brazilian households. Food purchases were converted into energy, carbon footprints and water footprints. Multiple linear regression models were used to assess the association between quintiles of beef and ultra-processed foods in total energy purchases and the environmental footprints, controlling for sociodemographic variables. RESULTS: Both beef and ultra-processed foods had a significant linear association with carbon and water footprints (P < 0·01) in crude and adjusted models. In the crude upper quintile of beef purchases, carbon and water footprints were 47·7 % and 30·8 % higher, respectively, compared to the lower quintile. The upper quintile of ultra-processed food purchases showed carbon and water footprints 14·4 % and 22·8 % higher, respectively, than the lower quintile. The greatest reduction in environmental footprints would occur when both beef and ultra-processed food purchases are decreased, resulting in a 21·1 % reduction in carbon footprint and a 20·0 % reduction in water footprint. CONCLUSIONS: Although the environmental footprints associated with beef consumption are higher, dietary patterns with lower consumption of beef and ultra-processed foods combined showed the greatest reduction in carbon and water footprints in Brazil. The high consumption of beef and ultra-processed foods is harmful to human health, as well as to the environment; thus, their reduction is beneficial to both.

Ultra-processed foods, adiposity and risk of head and neck cancer and oesophageal adenocarcinoma in the European Prospective Investigation into Cancer and Nutrition study: a mediation analysis.

PURPOSE: To investigate the role of adiposity in the associations between ultra-processed food (UPF) consumption and head and neck cancer (HNC) and oesophageal adenocarcinoma (OAC) in the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort. METHODS: Our study included 450,111 EPIC participants. We used Cox regressions to investigate the associations between the consumption of UPFs and HNC and OAC risk. A mediation analysis was performed to assess the role of body mass index (BMI) and waist-to-hip ratio (WHR) in these associations. In sensitivity analyses, we investigated accidental death as a negative control outcome. RESULTS: During a mean follow-up of 14.13 ± 3.98 years, 910 and 215 participants developed HNC and OAC, respectively. A 10% g/d higher consumption of UPFs was associated with an increased risk of HNC (hazard ratio [HR] = 1.23, 95% confidence interval [CI] 1.14-1.34) and OAC (HR = 1.24, 95% CI 1.05-1.47). WHR mediated 5% (95% CI 3-10%) of the association between the consumption of UPFs and HNC risk, while BMI and WHR, respectively, mediated 13% (95% CI 6-53%) and 15% (95% CI 8-72%) of the association between the consumption of UPFs and OAC risk. UPF consumption was positively associated with accidental death in the negative control analysis. CONCLUSIONS: We reaffirmed that higher UPF consumption is associated with greater risk of HNC and OAC in EPIC. The proportion mediated via adiposity was small. Further research is required to investigate other mechanisms that may be at play (if there is indeed any causal effect of UPF consumption on these cancers).

Food and Nutrition Surveillance System markers predict diet quality.

OBJECTIVE: To investigate the performance of food consumption markers of the Food and Nutrition Surveillance System (Sisvan) in assessing the overall dietary quality. METHODS: The study was carried out based on the reproduction of responses to markers in 24-hour recall data from 46,164 individuals aged ≥ 10 years, from the 2017-2018 Household Budget Survey (POF). Seven Sisvan markers were evaluated, and two scores were calculated for each participant, based on the sum of the number of healthy food markers (beans, fruits, and vegetables, ranging from 0 to 3) and unhealthy (hamburgers/sausages, sweetened beverages, instant noodles/salt snacks/crackers, stuffed cookies/sweets/candies, ranging from 0 to 4) consumed. Linear regression analyses were used to assess the association between scores and diet quality indicators (ultra-processed foods, dietary diversity, and levels of saturated and trans fat, added sugar, sodium, potassium, and fiber in the diet). RESULTS: The score of healthy eating markers increased significantly with increasing dietary diversity and potassium and fiber contents in the diet, while the opposite trend was observed for the densities of added sugar, sodium, saturated and trans fat (p < 0.001). The score of unhealthy eating markers increased significantly with the increase in the consumption of ultra-processed foods and densities of added sugar, saturated and trans fat levels in the diet, while an inverse trend was observed for potassium and fiber (p < 0.001). The joint analysis of the combination of the two marker scores showed that individuals with better performance (3 in the healthy food score, and 0 in the unhealthy food score) have a lower number of inadequacies in nutrient consumption. CONCLUSION: Sisvan food consumption markers, quickly and easily applied and already incorporated into the Brazilian public health system, have good potential to reflect the overall dietary quality.

Changes in dietary markers during the covid-19 pandemic in Brazil.

OBJECTIVE: Evaluate changes in the Brazilian population's diet and its determinants during the covid-19 pandemic. METHODS: We used diet data collected by the Datafolha Institute in 2019 (n = 1,384), 2020 (n =1,214), and 2021 (n = 1,459) from independent and representative samples of the adult population (aged 18 to 55 years) from all socioeconomic classes and geographic regions of Brazil. Food consumption was measured by checking the consumption of 22 sets of food on the day before the survey. The third cycle also included questions about changes in eating habits during the pandemic. We estimated the prevalence of consumption of the food sets in each cycle of the survey and used statistical tests for comparisons of proportions between the three cycles. RESULTS: Between 2019 and 2020, we observed a significant increase in the consumption of cereals, milk, packaged snacks or salty cookies, and industrialized sauces, as opposed to a decrease in the consumption of eggs. Between 2019 and 2021 and between 2020 and 2021, on the other hand, there was a significant decrease in the consumption of cereals, vegetables, fruits, and industrialized fruit juices and an increase in the consumption of soda, sweets, cookies, sausages, industrialized sauces, and ready meals. When asked about the main changes in the purchase and preparation of meals, 46.3% of the respondents reported consuming more food prepared at home during the pandemic. Regarding changes in eating habits, 48.6% of the respondents reported a change in their eating habits during the pandemic. The main reasons for such changes were greater concern with health (39.1%) and self-reported decreased family income (30.2%). CONCLUSIONS: The covid-19 pandemic had a negative impact on the diet of the population, and increased consumption of ultra-processed foods was reported for that period.

A novel web-based 24-h dietary recall tool in line with the Nova food processing classification: description and evaluation.

OBJECTIVE: This paper describes the first web-based self-completed 24-h recall designed to categorise food intake according to Nova groups - Nova24h - and its agreement with a reference tool in estimating the dietary relative contribution of the four Nova food groups (% of total energy intake). DESIGN: Comparisons of estimates of dietary relative contributions of Nova groups obtained by Nova24h and one standard interviewer-led 24-h recall. SETTING: Nationwide adult cohort study in Brazil. PARTICIPANTS: The subjects were 186 participants of the NutriNet Brasil Cohort Study (n 186). RESULTS: No statistically significant differences were observed between the Nova24h and the reference tool mean contributions of unprocessed or minimally processed foods (52·3 % v. 52·6 %), processed culinary ingredients (11·6 % v. 11·9 %), processed foods (17·1 % v. 14·7 %) and ultra-processed foods (19·0 % v. 20·9 %). Intraclass correlation coefficients between individual estimates obtained for each Nova group showed moderate to good agreement (0·54-0·78). Substantial or almost perfect agreement between the tools was seen regarding the ability to rank participants according to quintiles of contribution of each Nova group (PABAK 0·69-0·81). CONCLUSIONS: Nova24h is a suitable tool for estimating the dietary relative energy contribution of Nova food groups in the NutriNet Brasil cohort. New studies are necessary to verify its adequacy in other populations.

Sodium Intake Tracked from Infancy and Salt Taste Preference during Adolescence: Follow-up of a Randomized Controlled Field Trial in Brazil.

Background: Effective interventions to promote healthy sodium intakes require understanding factors driving liking for salt taste. Objectives: To examine effects of an early feeding intervention among low-income mothers on their children's energy and sodium intake and salt taste preferences at 12 years; and to identify age-related changes in dietary sodium sources. Methods: Secondary analyses were conducted on dietary intake and taste preference data collected from children in a longitudinal trial (NCT00629629). Mothers randomized to the intervention group received counseling on healthy eating practices for 1 year postpartum; the control group received no counseling. Two-day dietary recalls were obtained at 1 year (intervention end) and at 4-, 8-, and 12-year follow-up visits, from which foods were categorized as unprocessed, processed, or ultra-processed. At the 12-year visit, children's most preferred concentration of salt was measured using a validated, forced-choice, paired-comparison tracking method, and pubertal stage was self-assessed. Results: The intervention group had reduced energy intake compared with controls in all food categories at 1 year (P = 0.04) but not at the other time points. Sodium intake from processed foods increased from 4 to 12 years and from ultra-processed foods from 1 to 4; intake from unprocessed foods decreased from 1 to 8 year (all P < 0.01). At 12 years, children in early stages of puberty (Tanner stages 1-3; P = 0.04) or in the ≥75th percentile of sodium intake (P < 0.01) preferred significantly higher concentrations of salt than the other children. Conclusions: Both dietary intake of sodium and early puberty were associated with preferences for higher salt concentrations. Childhood and adolescence are important periods for understanding how experience and growth shape diet by changing salt taste. Clinical Trial Registration: This manuscript reports secondary analysis of data collected in trial NCT00629629 (2001-3) and follow-up [https://clinicaltrials.gov/ct2/show/NCT00629629?term=NCT00629629&draw=2&rank=1].

Consumption of ultra-processed foods in Brazil: distribution and temporal evolution 2008-2018.

OBJECTIVE: To evaluate sociodemographic factors associated with the consumption of ultra-processed foods and the temporal evolution of their consumption in Brazil between 2008 and 2018. METHODS: The study used food consumption data of individuals aged ≥ 10 years from 2008-2009 and 2017-2018 Pesquisas de Orçamentos Familiares (POF - Household Budget Surveys), grouping the foods according to the Nova classification. We used crude and adjusted linear regression models to assess the association between sociodemographic characteristics and consumption of ultra-processed foods in 2017-2018 and the temporal variation in their consumption between 2008 and 2018. RESULTS: Ultra-processed foods accounted for 19.7% of calories in 2017-2018. The adjusted analysis showed that their consumption was higher in women (versus men) and the South and Southeast regions (versus North) and lower in blacks (versus whites) and rural areas (versus urban), in addition to decreasing with the increased age and increasing with higher education and income. Consumption of ultra-processed foods increased by 1.02 percentage points (pp) from 2008-2009 to 2017-2018. This increase was significantly higher among men (+1.59 pp), black people (+2.04 pp), indigenous (+5.96 pp), in the rural area (+2.43 pp), those with up to 4 years of schooling (+1.18 pp), in the lowest income quintile (+3.54 pp), and the North (+2.95 pp) and Northeast (+3.11 pp) regions. On the other hand, individuals in the highest level of schooling (-3.30 pp) and the highest income quintile (-1.65 pp) reduced their consumption. CONCLUSIONS: The socioeconomic and demographic segments with the lowest relative consumption of ultra-processed foods in 2017-2018 are precisely those that showed the most significant increase in the temporal analysis, pointing to a trend towards national standardization at a higher level of consumption.

Food processing and cancer risk in Europe: results from the prospective EPIC cohort study.

BACKGROUND: Food processing has been hypothesised to play a role in cancer development; however, data from large-scale epidemiological studies are scarce. This study investigated the association between dietary intake according to amount of food processing and risk of cancer at 25 anatomical sites using data from the European Prospective Investigation into Cancer and Nutrition (EPIC) study. METHODS: This study used data from the prospective EPIC cohort study, which recruited participants between March 18, 1991, and July 2, 2001, from 23 centres in ten European countries. Participant eligibility within each cohort was based on geographical or administrative boundaries. Participants were excluded if they had a cancer diagnosis before recruitment, had missing information for the NOVA food processing classification, or were within the top and bottom 1% for ratio of energy intake to energy requirement. Validated dietary questionnaires were used to obtain information on food and drink consumption. Participants with cancer were identified using cancer registries or during follow-up from a combination of sources, including cancer and pathology centres, health insurance records, and active follow-up of participants. We performed a substitution analysis to assess the effect of replacing 10% of processed foods and ultra-processed foods with 10% of minimally processed foods on cancer risk at 25 anatomical sites using Cox proportional hazard models. FINDINGS: 521 324 participants were recruited into EPIC, and 450 111 were included in this analysis (318 686 [70·8%] participants were female individuals and 131 425 [29·2%] were male individuals). In a multivariate model adjusted for sex, smoking, education, physical activity, height, and diabetes, a substitution of 10% of processed foods with an equal amount of minimally processed foods was associated with reduced risk of overall cancer (hazard ratio 0·96, 95% CI 0·95-0·97), head and neck cancers (0·80, 0·75-0·85), oesophageal squamous cell carcinoma (0·57, 0·51-0·64), colon cancer (0·88, 0·85-0·92), rectal cancer (0·90, 0·85-0·94), hepatocellular carcinoma (0·77, 0·68-0·87), and postmenopausal breast cancer (0·93, 0·90-0·97). The substitution of 10% of ultra-processed foods with 10% of minimally processed foods was associated with a reduced risk of head and neck cancers (0·80, 0·74-0·88), colon cancer (0·93, 0·89-0·97), and hepatocellular carcinoma (0·73, 0·62-0·86). Most of these associations remained significant when models were additionally adjusted for BMI, alcohol and dietary intake, and quality. INTERPRETATION: This study suggests that the replacement of processed and ultra-processed foods and drinks with an equal amount of minimally processed foods might reduce the risk of various cancer types.

Ultra-processed food consumption, cancer risk and cancer mortality: a large-scale prospective analysis within the UK Biobank.

Background: Global dietary patterns are increasingly dominated by relatively cheap, highly palatable, and ready-to-eat ultra-processed foods (UPFs). However, prospective evidence is limited on cancer development and mortality in relation to UPF consumption. This study examines associations between UPF consumption and risk of cancer and associated mortality for 34 site-specific cancers in a large cohort of British adults. Methods: This study included a prospective cohort of UK Biobank participants (aged 40-69 years) who completed 24-h dietary recalls between 2009 and 2012 (N = 197426, 54.6% women) and were followed up until Jan 31, 2021. Food items consumed were categorised according to their degree of food processing using the NOVA food classification system. Individuals' UPF consumption was expressed as a percentage of total food intake (g/day). Prospective associations were assessed using multivariable Cox proportional hazards models adjusted for baseline socio-demographic characteristics, smoking status, physical activity, body mass index, alcohol and total energy intake. Findings: The mean UPF consumption was 22.9% (SD 13.3%) in the total diet. During a median follow-up time of 9.8 years, 15,921 individuals developed cancer and 4009 cancer-related deaths occurred. Every 10 percentage points increment in UPF consumption was associated with an increased incidence of overall (hazard ratio, 1.02; 95% CI, 1.01-1.04) and specifically ovarian (1.19; 1.08-1.30) cancer. Furthermore, every 10 percentage points increment in UPF consumption was associated with an increased risk of overall (1.06; 1.03-1.09), ovarian (1.30; 1.13-1.50), and breast (1.16; 1.02-1.32) cancer-related mortality. Interpretation: Our UK-based cohort study suggests that higher UPF consumption may be linked to an increased burden and mortality for overall and certain site-specific cancers especially ovarian cancer in women.

Characteristics associated with dietary patterns in Brazilian children under two years of age.

OBJECTIVE: To analyze the dietary patterns of Brazilian children under two years of age and assess their association with sociodemographic characteristics and health service use. METHODS: This is a cross-sectional study with data from the 2013 National Health Survey (PNS). Patterns were found for two age groups by principal component analysis and their correlation with characteristics of interest was tested by linear regression models. RESULTS: We found two dietary patterns for our groups. The first consisted of the consumption of fresh or minimally processed foods and the second, of ultra-processed foods. The greater adherence of children between six and 11 months to the first pattern was associated with higher per capita family income and urban residences in the most developed regions of Brazil. At 12 months or more, adherence related to white race/color, higher per capita family incomes, residence in more developed regions, and visits to private childcare. Adherence to the second pattern among children under one year of age was inversely associated with Yellow or Indigenous race/color, residence in the Brazilian Northeast, and childcare in specialized public or private services. At 12 months or more, greater adherence was directly associated with Black or Brown children who resided in more developed regions, and inversely associated with those living in the Brazilian Northeast. CONCLUSION: We found two opposite dietary patterns in Brazilian children under two years of age and that several social determinants modify their chance of adhering to these patterns.

Food Processing and Risk of Crohn's Disease and Ulcerative Colitis: A European Prospective Cohort Study.

BACKGROUND & AIMS: Industrial foods have been associated with increased risks of several chronic conditions. We investigated the relationship between the degree of food processing and risks of Crohn's disease (CD) and ulcerative colitis (UC) in the European Prospective Investigation into Cancer and Nutrition cohort. METHODS: Analyses included 413,590 participants (68.6% women; mean baseline age, 51.7 y) from 8 European countries. Dietary data were collected at baseline from validated country-specific dietary questionnaires. Associations between proportions of unprocessed/minimally processed and ultraprocessed food intake and CD and UC risks were estimated using Cox models to obtain hazard ratios (HRs) and 95% CIs. Models were stratified by center, age, and sex, and adjusted for smoking status, body mass index, physical activity, energy intake, educational level, and alcohol consumption. RESULTS: During a mean follow-up period of 13.2 years, 179 incident cases of CD and 431 incident cases of UC were identified. The risk of CD was lower in people consuming high proportions of unprocessed/minimally processed foods (adjusted HR for the highest vs lowest quartile: 0.57; 95% CI, 0.35-0.93; P trend < .01), particularly fruits and vegetables (adjusted HRs, 0.54; 95% CI, 0.34-0.87 and 0.55; 95% CI, 0.34-0.91, respectively). There was no association between unprocessed/minimally processed food intake and the risk of UC. No association was detected between ultraprocessed food consumption and CD or UC risks. CONCLUSIONS: In the European Prospective Investigation into Cancer and Nutrition cohort, consumption of unprocessed/minimally processed foods was associated with a lower risk of CD. No association between UC risk and food processing was found.

Ultra-processed food consumption deteriorates the profile of micronutrients consumed by Portuguese adults and elderly: the UPPER project.

PURPOSE: This study aims to describe micronutrient intake according to food processing degree and to investigate the association between the dietary share of ultra-processed foods and micronutrient inadequacies in a representative sample of Portuguese adult and elderly individuals. METHODS: Cross-sectional data from the National Food, Nutrition and Physical Activity Survey (2015/2016) were used. Food consumption data were collected through two 24-h food recalls, and food items were classified according to the NOVA system. Linear regression models were used to assess the association between the micronutrient density and the quintiles of ultra-processed food consumption-crude and adjusted. Negative Binomial regressions were performed to measure the prevalence ratio of micronutrient inadequacy according to ultra-processed food quintiles. RESULTS: For adults, all evaluated vitamins had significantly lower content in the fraction of ultra-processed foods compared to unprocessed or minimally processed foods, except vitamin B2. For the elderly, out of ten evaluated vitamins, seven presented significantly less content in ultra-processed foods compared to non-processed ones. The higher energy contribution of ultra-processed foods in adults was associated with a lower density of vitamins and minerals. This association was not observed in the elderly. For adults, compared with the first quintile of ultra-processed food consumption, the fifth quintile was positively associated with inadequate intakes of vitamin B6 (PR 1.51), vitamin C (PR 1.32), folate (PR 1.14), magnesium (PR 1.21), zinc (PR 1.33), and potassium (PR 1.19). CONCLUSION: Our results corroborate the importance of public health actions that promote a reduction in the consumption of ultra-processed foods.

Trends in food consumption according to the degree of food processing among the UK population over 11 years.

Although ultra-processed foods represent more than half of the total energy consumed by the UK population, little is known about the trend in food consumption considering the degree of food processing. We evaluated the trends of the dietary share of foods categorised according to the NOVA classification in a historical series (2018-2019) among the UK population. Data were acquired from the NDNS, a survey that collects diet information through a 4-d food record. We used adjusted linear regression to estimate the dietary participation of NOVA groups and evaluated the linear trends over the years. From 2008 to 2019, we observed a significant increase in the energy share of culinary ingredients (from 3·7 to 4·9 % of the total energy consumed; P-trend = 0·001), especially for butter and oils; and reduction of processed foods (from 9·6 to 8·6 %; P-trend = 0·002), especially for beer and wine. Unprocessed or minimally processed foods (≅30 %, P-trend = 0·505) and ultra-processed foods (≅56 %, P-trend = 0·580) presented no significant change. However, changes in the consumption of some subgroups are noteworthy, such as the reduction in the energy share of red meat, sausages and other reconstituted meat products as well as the increase of fruits, ready meals, breakfast cereals, cookies, pastries, buns and cakes. Regarding the socio-demographic characteristics, no interaction was observed with the trend of the four NOVA groups. From 2008 to 2019 was observed a significant increase in culinary ingredients and a reduction in processed food. Furthermore, it sheds light on the high share of ultra-processed foods in the contemporary British diet.

Changes in dietary markers during the covid-19 pandemic in Brazil / Mudanças nos marcadores da alimentação durante a pandemia de covid-19 no Brasil

ABSTRACT OBJECTIVE Evaluate changes in the Brazilian population's diet and its determinants during the covid-19 pandemic. METHODS We used diet data collected by the Datafolha Institute in 2019 (n = 1,384), 2020 (n =1,214), and 2021 (n = 1,459) from independent and representative samples of the adult population (aged 18 to 55 years) from all socioeconomic classes and geographic regions of Brazil. Food consumption was measured by checking the consumption of 22 sets of food on the day before the survey. The third cycle also included questions about changes in eating habits during the pandemic. We estimated the prevalence of consumption of the food sets in each cycle of the survey and used statistical tests for comparisons of proportions between the three cycles. RESULTS Between 2019 and 2020, we observed a significant increase in the consumption of cereals, milk, packaged snacks or salty cookies, and industrialized sauces, as opposed to a decrease in the consumption of eggs. Between 2019 and 2021 and between 2020 and 2021, on the other hand, there was a significant decrease in the consumption of cereals, vegetables, fruits, and industrialized fruit juices and an increase in the consumption of soda, sweets, cookies, sausages, industrialized sauces, and ready meals. When asked about the main changes in the purchase and preparation of meals, 46.3% of the respondents reported consuming more food prepared at home during the pandemic. Regarding changes in eating habits, 48.6% of the respondents reported a change in their eating habits during the pandemic. The main reasons for such changes were greater concern with health (39.1%) and self-reported decreased family income (30.2%). CONCLUSIONS The covid-19 pandemic had a negative impact on the diet of the population, and increased consumption of ultra-processed foods was reported for that period.

RESUMO OBJETIVO Analisar mudanças na alimentação da população brasileira e seus determinantes durante a pandemia de covid-19. MÉTODOS Foram utilizados dados de alimentação coletados pelo instituto Datafolha, em 2019 (n = 1.384), 2020 (n = 1.214) e 2021 (n = 1.459), de amostras independentes e representativas da população adulta (entre 18 e 55 anos) de todas as classes socioeconômicas e regiões geográficas do Brasil. O consumo alimentar foi aferido por meio da verificação do consumo de 22 conjuntos de alimentos no dia anterior à pesquisa. No terceiro ciclo, também foram incluídas questões sobre mudanças nos hábitos alimentares durante a pandemia. Estimou-se a prevalência de consumo dos conjuntos de alimentos em cada ciclo da pesquisa e foram utilizados testes estatísticos para comparações de proporções entre os três ciclos. RESULTADOS Observou-se, entre 2019 e 2020, aumento significativo no consumo de cereais, leite, salgadinhos de pacote ou biscoitos salgados e molhos industrializados, em contraponto à diminuição do consumo de ovos. Entre 2019 e 2021 e entre 2020 e 2021, por outro lado, houve diminuição significativa no consumo de cereais, hortaliças, frutas e sucos de fruta industrializados e aumento no consumo de refrigerante, biscoito doce, recheado ou bolinho de pacote, embutidos, molhos industrializados e refeições prontas. Quando questionados sobre as principais mudanças na compra e preparo das refeições, 46,3% dos entrevistados relataram consumir mais alimentos preparados em casa durante a pandemia. Em relação a mudanças nos hábitos alimentares, 48,6% dos entrevistados relataram alteração na alimentação durante a pandemia. Os principais motivos para tais mudanças foram maior preocupação com a saúde (39,1%) e autorrelato de diminuição da renda familiar (30,2%). CONCLUSÕES A pandemia de covid-19 teve impacto negativo na alimentação da população, e foi reportado aumento no consumo de alimentos ultraprocessados durante esse período.

Food and Nutrition Surveillance System markers predict diet quality / Marcadores do Sistema de Vigilância Alimentar e Nutricional predizem qualidade da dieta

ABSTRACT OBJECTIVE To investigate the performance of food consumption markers of the Food and Nutrition Surveillance System (Sisvan) in assessing the overall dietary quality. METHODS The study was carried out based on the reproduction of responses to markers in 24-hour recall data from 46,164 individuals aged ≥ 10 years, from the 2017-2018 Household Budget Survey (POF). Seven Sisvan markers were evaluated, and two scores were calculated for each participant, based on the sum of the number of healthy food markers (beans, fruits, and vegetables, ranging from 0 to 3) and unhealthy (hamburgers/sausages, sweetened beverages, instant noodles/salt snacks/crackers, stuffed cookies/sweets/candies, ranging from 0 to 4) consumed. Linear regression analyses were used to assess the association between scores and diet quality indicators (ultra-processed foods, dietary diversity, and levels of saturated and trans fat, added sugar, sodium, potassium, and fiber in the diet). RESULTS The score of healthy eating markers increased significantly with increasing dietary diversity and potassium and fiber contents in the diet, while the opposite trend was observed for the densities of added sugar, sodium, saturated and trans fat (p < 0.001). The score of unhealthy eating markers increased significantly with the increase in the consumption of ultra-processed foods and densities of added sugar, saturated and trans fat levels in the diet, while an inverse trend was observed for potassium and fiber (p < 0.001). The joint analysis of the combination of the two marker scores showed that individuals with better performance (3 in the healthy food score, and 0 in the unhealthy food score) have a lower number of inadequacies in nutrient consumption. CONCLUSION Sisvan food consumption markers, quickly and easily applied and already incorporated into the Brazilian public health system, have good potential to reflect the overall dietary quality.

RESUMO OBJETIVO Investigar o desempenho dos marcadores do consumo alimentar do Sistema de Vigilância Alimentar e Nutricional (Sisvan) na avaliação da qualidade global da alimentação. MÉTODOS O estudo foi realizado a partir da reprodução de respostas aos marcadores em dados de recordatórios de 24 horas, de 46.164 indivíduos com idade menor ou igual a 10 anos, da Pesquisa de Orçamentos Familiares 2017-2018. Foram avaliados sete marcadores do Sisvan e calculados dois escores para cada participante, a partir do somatório do número de marcadores de alimentação saudável (feijão, frutas, verduras/legumes, variando de 0 a 3) e não saudável (hambúrguer/embutidos, bebidas adoçadas, macarrão instantâneo/salgadinhos/biscoitos salgados, biscoito recheado/doces/guloseimas, variando de 0 a 4) consumidos. Análises de regressão linear foram usadas para avaliar a associação entre os escores e indicadores de qualidade da alimentação (participação de alimentos ultraprocessados, diversidade e teores de gordura saturada, trans, açúcar de adição, sódio, potássio e fibra da dieta). RESULTADOS o escore de marcadores de alimentação saudável aumentou de forma significativa com o aumento da diversidade e dos teores de potássio e fibra da dieta, enquanto tendência oposta foi observada para as densidades de açúcar de adição, sódio, gordura saturada e trans (p < 0,001). Observou-se que o escore de marcadores de alimentação não saudável aumentou de forma significativa com o aumento da participação de alimentos ultraprocessados e dos teores de açúcar de adição, gordura saturada e trans da dieta, enquanto tendência inversa é observada para potássio e fibra (p < 0,001). A análise conjunta da combinação dos dois escores de marcadores mostrou que indivíduos com melhor desempenho (3 no escore de alimentos saudáveis, e 0 no de alimentos não saudáveis) possuem menor número de inadequações no consumo de nutrientes. CONCLUSÃO Os marcadores do consumo alimentar do Sisvan, aplicados de forma rápida e prática e já incorporados no sistema público de saúde brasileiro, possuem bom potencial para refletir a qualidade global da alimentação.
