RESUMEN
OBJECTIVE: To estimate the disability and costs of the Brazilian Unified Health System for IHD attributable to trans-fatty acid (TFA) consumption in 2019. DESIGN: This ecological study used secondary data from the Global Burden of Disease (GBD) Study 2019 to estimate the years lived with disability from IHD attributable to TFA in Brazil in 2019. Data on direct costs (purchasing power parity: 1 Int$ = R$ 2·280) were obtained from the Hospital and Ambulatory Information Systems of the Brazilian Unified Health System. Moreover, the total costs in each state were divided by the resident population in 2019 and multiplied by 10 000 inhabitants. The relationship between the socio-demographic index, disease and economic burden was investigated. SETTING: Brazil and its twenty-seven states. PARTICIPANTS: Adults aged ≥ 25 years of both sexes. RESULTS: IHD attributable to TFA consumption resulted in 11 165 years lived with disability (95 % uncertainty interval 93218 462) in 2019 in Brazil. A total of Int$ 54 546 227 (95 % uncertainty interval 4 505 79285 561 810) was spent in the Brazilian Unified Health System in 2019 due to IHD attributable to TFA, with the highest costs of hospitalisations, for males and individuals aged ≥ 50 years or over. The highest costs were observed in Sergipe (Int$ 6508/10 000; 95 % uncertainty interval 57610 265), followed by the two states from the South. Overall, as the socio-demographic index increases, expenditures increase. CONCLUSIONS: TFA consumption results in a high disease and economic IHD burden in Brazil, reinforcing the need for more effective health policies, such as industrial TFA elimination, following the international agenda.

The objectives were to compare the evolution of dietary folate intake, to estimate the prevalence of folate inadequacy (POFI) and the contribution of food groups to folate intake (dietary folate plus folic acid from fortified foods) in two post-fortification periods in the Brazilian population, according to life stages, geographic regions and per capita income. Population-based study including representative data from the National Dietary Survey - Brazilian Household Budget Surveys (NDS-HBS) 2008-2009 and 2017-2018, with a total of 32 749 (2008-2009) and 44 744 (2017-2018) individuals aged ≥ 10 years old, excluding pregnant and lactating women. The National Cancer Institute method was used to estimate the distributions of usual dietary folate intake. POFI was estimated according to estimated average requirement cut-off point method. After 10 years of the first NDS-HBS, POFI has increased in all sex-age groups, except for 10-13 years. POFI among women of reproductive age was around 30 and 40 % in 2008-2009 and 2017-2018. Higher POFI was observed in the North region. The top five food groups contributors to folate intake in Brazil were beans, breads, pasta and pizza, cakes and cookies and non-alcoholic beverages groups in both periods, differing in the rank order of the last two groups. Although being a country that has adopted mandatory folic acid flour fortification for almost two decades, increased POFI was observed in 2017-2018. This study brings significant scientific information, which can help understand folate dietary data in different contexts and consequently guide the approach for public health fortification strategies.

Achieving nutritional adequacy requires an increase in fresh foods consumption, which may increase pesticide intakes. This study aimed to identify required dietary modifications to achieve nutritional adequacy without exceeding the acceptable daily intake (ADI) for pesticides. Data from the National Dietary Survey 2017-2018 were linked to the pesticide database from the Program on Pesticide Residue Analysis in Food. We performed linear programming models to design nutritionally adequate diets constrained by food preferences for different constraints on pesticide intake at the least cost increment. Nutritional adequacy led to an increase in pesticide intakes without exceeding their ADI. Modifications in diets varied according to the model, but, in general, consisted in an increase in fruits and vegetables, dairy, and seafood, and a reduction in rice, red meat, and sugar-sweetened beverages quantities. In conclusion, meeting nutritional adequacy increases pesticide intake compared to the observed diets, without representing a health concern to consumers.

The aim was to design culturally acceptable and healthy diets with reduced energetic share of ultra-processed foods (UPF%) at no cost increment and to evaluate the impact of the change in the UPF% on diet quality. Food consumption and price data were obtained from the Household Budget Survey (n 55 970 households) and National Dietary Survey (n 32 749 individuals). Linear programming models were performed to design diets in which the mean population UPF% was reduced up to 5 % with no cost increment relative to the observed costs. The models were isoenergetic or allowed the energy content to vary according to the UPF%, and they were not constrained to nutritional goals (nutrient-free models) or maximised the compliance with dietary recommendations (nutrient-constrained models). Constraints regarding food preference were introduced in the models to obtain culturally acceptable diets. The mean population UPF% was 23·8 %. The lowest UPF% attained was approximately 10 %. The optimised diet cost was up to 20 % cheaper than the observed cost, depending on the model and the income level. In the optimised diets, the reduction in the UPF% was followed by an increase in fruits, vegetables, beans, tubers, dairy products, nuts, fibre, K, Mg, vitamin A and vitamin C in the nutrient-constrained models, compared with the observed consumption in the population. There was little variation in most nutrients across the UPF% reduction. The UPF% reduction in the nutrient-free models impacted only trans-fat and added sugar content. UPF% reduction and increase in diet quality are possible at no cost increment.

BACKGROUND: Meeting nutrient intake recommendations may demand substantial modifications in dietary patterns, and may increase diet cost. Incentives for modifying one's dietary intake that disregard prices are unlikely to be effective in the general population, especially among low-income strata, due to the high percentage of income committed to food purchases. The aim of this study is to evaluate how much the nutrient content can be increased through a modeled diet, without any cost increase, for low-income Brazilian households. METHODS: Low-income households were selected from the Household Budget Survey (24,688 households) and National Dietary Survey (6,032 households, 16,962 individuals), from where we obtained food prices and consumption data. Food quantities were modeled using linear programming to find diets that meet nutritional recommendations in two sets of models: cost-constrained (the cost should not be higher than the observed diet cost) and cost-free. Minimum and maximum amounts of each food in the modelled diets were allowed at three levels of food acceptability: rigorous (least deviance from the current observed diets), moderate, and flexible (higher deviance from the current observed diets). RESULTS: We found no feasible solution that would accommodate all the nutritional targets. The most frequent limiting nutrients were calcium; vitamins D, E, and A; zinc; fiber; sodium; and saturated and trans-fats. However, increases in nutrient contents were observed, especially for fiber, calcium, copper, magnesium, vitamin A, vitamin C, and vitamin E. In general, the best achievement was obtained with cost-free models. Fruits and beans increased in all models; large increase in whole cereals was observed only in the flexible models; large increase in vegetables was observed only in the cost-free models; and fish increased only in the cost-free models. Reductions were observed for rice, red and processed meats, sugar-sweetened beverages, and sweets. The mean observed cost was US$2.16 per person/day. The mean cost in the cost-free models was US$2.90 (moderate), US$2.70 (rigorous), and US$2.60 (flexible). CONCLUSION: The complete nutritional adequacy is unattainable, although feasible changes would substantially improve diet quality by improving nutrient content without additional costs.

OBJECTIVE: The present study aimed to compare Household Budget Survey (HBS) data on food purchasing and individual food consumption, collected in the same nationwide survey. DESIGN: Food purchase information for each household was collected by a seven-day collective acquisition diary, applied to 55 970 households. Food consumption information was obtained from household members over 10 years old by the application of two non-consecutive food records in a sub-sample of the HBS. Cooking and correction factors were applied when necessary, and all food items reported were grouped into twelve main food groups. Food purchase and consumption data were presented as absolute weight (g/person per d) and as relative contribution to energy intake (%) for the overall study population, which was stratified according to household income. SETTING: Brazil.ParticipantsNational estimates of food consumption and purchase for Brazil. RESULTS: The greatest differences between purchase and consumption data (purchase minus consumption) were observed for meat (-168 g), beans/legumes (-48 g), roots/tubers (-36 g) and fruits (-31 g). When expressed in terms of energy contribution, the highest differences were found for cereals (13 %) and oils and fats (11 %). Differences between purchase and consumption data were generally lower in the highest compared with the lowest household income quintile; and were lower for most main food groups when considering only foods reported as being eaten at home. CONCLUSIONS: With few exceptions, food purchase expressed as relative energy contribution, as opposed to absolute weight, can provide a good picture of actual consumption in the Brazilian population.

RESUMEN
We aim to identify the dietary changes to improve nutrition and reduce diet-related greenhouse gas emission (GHGE) simultaneously in Brazil, taking into account the heterogeneity in food habits and prices across the country. Food consumption and prices were obtained from two nationwide surveys (n = 55,970 households and 34,003 individuals). Linear programming models were performed to design optimised diets most resembling the observed diets, and meeting different sets of constraints: (i) nutritional, for preventing chronic diseases and meeting nutrient adequacy; (ii) socio-cultural: by respecting food preferences; and (iii) environmental: by reducing GHGE by steps of 10%. Moving toward a diet that meets nutritional recommendations led to a 14% to 24% cost increase and 10% to 27% GHGE reduction, depending on the stringency of the acceptability constraints. Stronger GHGE reductions were achievable (up to about 70%), with greater departure from the current diet, but not achieving calcium and potassium goals. Diet cost increment tended to be mitigated with GHGE reduction in most models, along with reductions in red meat, chicken, eggs, rice, and high-fat sugar sodium foods.

BACKGROUND: The Food Guide for the Brazilian Population relies on natural or minimally processed foods mainly of plant origin such as beans and rice with low oil, salt, and sugar content and limited consumption of ultraprocessed foods. Reduction of ultraprocessed foods improves diet quality and energy consumption. OBJECTIVE: The goal of this study is to evaluate the effectiveness of an intervention for the treatment of obesity in children, with counseling based on the Brazilian Food Guide plus control of total energy intake. METHODS: A parallel, randomized clinical trial will include children aged 7 to 12 years. Randomization will be performed in blocks of 10 individuals using computer-generated random sequence numbers. Both the control and intervention groups will participate in 6 standardized educational activities based on the 10 steps of the Brazilian Food Guide. These activities will be conducted at the University Hospital Toy Library, located in the pediatric outpatient clinic. For the intervention group, in addition to the educational activities, an individualized food plan based on the nutritional recommendations of the Brazilian Society of Pediatrics will be prescribed and discussed with the mothers and fathers. The primary outcome of the study will be variations in body mass index, and secondary outcomes will include analysis of insulin resistance, blood pressure, body fat percentage, and waist and neck circumference. RESULTS: This project was funded by the National Council for Scientific and Technological Development in December 2017 (grant no 408333/2017-0). Recruitment began in August 2018 and by September 2019, we had enrolled the 101 participants. In addition to the patients referred by the national system of regulation, recruitment was made by medical outpatient referral and external indication. This is an ongoing study. We expect the results to be published in November 2020. CONCLUSIONS: At the end of the project, in case of a positive result, a protocol for the treatment of obesity based on the Brazilian Food Guide will be proposed to the Unified Health System. A successful method to reduce childhood obesity is expected. TRIAL REGISTRATION: Brazilian Registry of Clinical Trials RBR-3st5sn; http://www.ensaiosclinicos.gov.br/rg/RBR-3st5sn.

RESUMEN
Trata-se de estudo transversal de base populacional com residentes do Município de São Paulo, Brasil, que objetivou avaliar a prevalência do uso de suplementos dietéticos, segundo estágio de vida e características sociodemográficas e comportamentais. Observou-se baixa prevalência do uso de suplementos (6,35%) entre os 865 indivíduos entrevistados, havendo maior prevalência entre mulheres (RP = 1.88; IC95%: 1,08-1,25). Não foi encontrada diferença estaticamente significante para as demais variáveis. Suplementos compostos por vitamina(s) e mineral(is) combinados lideraram o uso; no entanto, o consumo de suplementos pode ainda ser considerado baixo na população estudada. Tendo em vista as fracas evidências atuais de benefícios obtidos pelo uso regular de suplementos, em conjunto com os riscos para o consumo excessivo, justifica-se o monitoramento e vigilância do uso de suplementos na população.
This cross-sectional population-based study in the city of São Paulo, Brazil, aimed to assess prevalence of use of dietary supplements according to life stage and socio-demographic and behavioral characteristics. Prevalence of supplement use was low (6.35%) among the 865 individuals interviewed, with a higher prevalence among women (PR = 1.88; 95%CI: 1.08-1.25). However, no statistically significant difference was found for the other variables. Combined vitamin and mineral supplements headed the list. Intake of supplements is still low in this population. However, the current weak evidence of benefits from regular use and the risks of excessive consumption justify monitoring the use of supplements.

Analisou-se a ingestão de folato nos períodos pré e pós-fortificação. Os dados dietéticos foram coletados por recordatório de 24 horas (R24h) no Inquérito de Saúde de São Paulo (ISA-Capital) em 2003 e 2007/2008, estratificando-se a população segundo fase da vida e sexo. Utilizaram-se os valores de recomendação: necessidade média estimada (EAR) e nível máximo de ingestão tolerada (UL) e o método "EAR como ponto de corte" para estimar a inadequação da ingestão. Houve redução na prevalência de inadequação da ingestão de folato em todos os estratos, com destaque para os adolescentes e adultos do sexo masculino, de 72% para < 1% e de 76% para 6%, mas nas mulheres adultas a inadequação permaneceu elevada (38%). Antes da fortificação, o feijão foi o alimento que mais contribuiu para a ingestão de folato; após, o maior contribuinte passou a ser o pão, porém o feijão permaneceu importante. A fortificação foi bem-sucedida (aumentou a ingestão dentro de níveis seguros), porém, gera preocupação a elevada proporção no grupo alvo, mulheres adultas, que não atingem a recomendação para ingestão de folato.
This study analyzed folic acid intake before and since mandatory fortification. Dietary data were collected by 24-hour recall in a health survey in São Paulo (ISA-Capital) in 2003 and 2007-2008, stratifying the population according to life stage and gender. Estimated average requirement (EAR) and tolerable upper intake level (UL) were used to assess intake. Prevalence of inadequate folic acid intake decreased in all groups, especially adolescents and adult males (72% to < 1% and 76% to 6%, respectively) but remained high in adult women (38%). Beans were the main source of folic acid before fortification. With fortification, bread became the main source, but beans remained important. Fortification was successful (increased intake within safe levels), but it raised concerns about the high proportion in the target group (adult women) who still fail to meet the recommended intake.

Los datos dietéticos se recogieron mediante un recordatorio de 24 horas en la Encuesta de Salud de São Paulo (ISA-Capital) en 2003 y 2007/2008, estratificando la población según etapa de la vida y sexo. Se utilizaron los valores de recomendación: necesidad media estimada (EAR) y la ingesta máxima tolerable (UL) y el método "EAR como punto de corte" para estimar la ingesta inadecuada. Se observó una reducción en la prevalencia de ingesta inadecuada de folato en todos los grupos, especialmente en los adolescentes y adultos varones, de un 72% a < 1% y de un 76% a un 6%, no obstante, en las mujeres adultas, la inadecuación seguía siendo alta (38%). Antes de la fortificación, los frijoles son el alimento que más contribuye a la ingesta de folato, después es el pan el que también constituye una fuente de folato, pese a que los frijoles siguen siendo los más importantes. La fortificación fue exitosa (aumento de la ingesta dentro de niveles seguros), sin embargo, se plantea una preocupación por el alto porcentaje del grupo objetivo: mujeres adultas que no cumplen con la recomendación para la ingesta de ácido fólico.

OBJETIVO Avaliar a distribuição da ingestão de ácido fólico e a segurança de diferentes doses de suplementos em mulheres em idade reprodutiva. MÉTODOS Foram utilizados dados de consumo a partir de dois dias não consecutivos de registro alimentar de 6.837 mulheres em idade reprodutiva (19 a 40 anos) participantes do Inquérito Nacional de Alimentação, módulo da Pesquisa de Orçamentos Familiares 2008-2009. Médias e percentis de consumo habitual de folato natural e ácido fólico foram estimados utilizando o método do National Cancer Institute . Cinco cenários foram simulados somando-se diferentes doses diárias de fortificação (400 mcg, 500 mcg, 600 mcg, 700 mcg e 800 mcg) ao ácido fólico oriundo dos alimentos consumidos pelas mulheres. Comparou-se o total de ácido fólico (dieta + suplemento) com o nível máximo de ingestão tolerável (UL = 1.000 mcg) para definir a dose segura de suplementação. RESULTADOS Mulheres com ingestão habitual de ácido fólico acima do nível máximo de ingestão tolerável foram observadas para doses de suplemento de 800 mcg (7,0% das mulheres). Abaixo desse valor, qualquer dose de suplementação mostrou-se segura. CONCLUSÕES O uso de suplementos de até 700 mcg de ácido fólico mostrou-se seguro. .

OBJECTIVE To evaluate the distribution of folic acid intake and the safety of different doses of supplements in women of childbearing age. METHODS Data were used from two non-consecutive days of food records of 6,837 women of childbearing age (19-40 years old) participants of the National Food Survey, a module of the Household Budget Survey 2008-2009. Means and percentiles of usual consumption of natural folate and folic acid were estimated using the National Cancer Institute method. Five scenarios were simulated by adding different daily doses of fortification (400 mcg, 500 mcg, 600 mcg, 700 mcg and 800 mcg) to folic acid derived from food consumed by the women. To define a safe dose of the supplement, the total folate (dietary + supplement) was compared with the tolerable upper intake level (UL = 1,000 mcg). RESULTS Women with usual intake of folic acid above the tolerable upper intake levels were observed only for doses of supplement of 800 mcg (7.0% of women). Below this value, any dose of the supplement was safe. CONCLUSIONS The use of supplements of up to 700 mcg of folic acid was shown to be safe. .
