RESUMEN

BACKGROUND: Poor diet quality contributes to morbidity and mortality and affects environmental sustainability. The EAT-Lancet reference diet offers a healthy and sustainable solution. This study aimed to estimate the association between diet cost and dietary quality, measured with an EAT-Lancet Index. METHODS: An EAT-Lancet index was adapted to assess adherence to this dietary pattern from 24-h recalls data from the 2012 and 2016 Mexican National Health and Nutrition Surveys (n = 14,242). Prices were obtained from the Consumer Price Index. We dichotomized cost at the median (into low- and high-cost) and compared the EAT-Lancet index scores. We also used multivariate linear regression models to explore the association between diet cost and diet quality. RESULTS: Individuals consuming a low-cost diet had a higher EAT-Lancet score than those consuming a high-cost diet (20.3 vs. 19.4 from a possible scale of 0 to 42; p < 0.001) due to a lower intake of beef and lamb, pork, poultry, dairy, and added sugars. We found that for each one-point increase in the EAT-Lancet score, there was an average decrease of MXN$0.4 in the diet cost (p < 0.001). This association was only significant among low- and middle-SES individuals. CONCLUSIONS: Contrary to evidence from high-income countries, this study shows that in Mexico, adhering to the EAT-Lancet reference diet is associated with lower dietar costs, particularly in lower SES groups. These findings suggest the potential for broader implementation of healthier diets without increasing the financial burden.

RESUMEN

The objective of this study was to evaluate the economic and financial viability of finishing of two sexes of Brazilian Somalis sheep in feedlot receiving diets with 0 and 15% reduction in the total digestible nutrients and crude protein contents. A completely randomized design was adopted, in a 2 × 2 factorial arrangement, with treatments consisting of two sexes (non-castrated males (21.13 ± 5.00 kg) and females (17.99 ± 3.79 kg) and two diets (0 and 15% reduction in the levels of total digestible nutrients and crude protein). Four simulations of productive scenarios were carried out: non-castrated males receiving the diet with 0% reduction; non-castrated males receiving the diet with 15% reduction; females receiving the diet with 0% reduction and females receiving the diet with 0% reduction, for a period of 70 days in feedlot. The highest costs of the system were with feeding and other costs, mainly the acquisition of animals. For both sexes, the 0% reduction diet showed the highest total cost, total revenue, break-even point. Non-castrated males fed a non-reduced diet and females fed a 15% reduction diet had higher net income, rate of return, total productivity, net present value, internal rate of return, profitability index and profitability rate. Less favorable situations were not profitable for any scenario. However, the increase in sales price favorability makes the activity viable. The reduction of total digestible nutrients and crude protein affects the economic and financial viability of Brazilian Somalis sheep. For non-castrated males it is recommended the diet without reduction and for females the diet with 15% reduction of nutrients.

RESUMEN

The 2023 Mexican Healthy and Sustainable Dietary Guidelines (HSDG 2023) were developed to include all dimensions of sustainability. Here we compare the environmental impact and cost of diets based on the HSDG 2023, current diets and the Mexican-adapted EAT healthy reference diet. Diets following HSDG 2023 are 21% less expensive, require 30% less land to be produced and have 34% less carbon emissions than current diets-particularly in Mexico City and other urban areas with higher prevalence of Westernized diets. This is driven by reduced animal-source food, especially red meat, and ultra-processed foods. In south-rural areas, the water footprint and cost of diets following HSDG 2023 were higher than those of current diets owing to increased intake of nuts, fruits and vegetables not offset by lower meat consumption (which is already close to recommendations). Diet environmental impact and cost could be further reduced with the Mexican-adapted EAT healthy reference diet compared with the HSDG 2023.

RESUMEN

BACKGROUND: While healthy and sustainable diets benefit human and planetary health, their monetary cost has a direct impact on consumer food choices. This study aimed to identify the cost and environmental impact of the current Brazilian diet (CBD) and compare it with healthy and sustainable diets. METHODS: Data from the Brazilian Household Budget Survey 2017/18 and the Footprints of Foods and Culinary Preparations Consumed in Brazil database were used for a modeling study comparing the cost of healthy and sustainable diets (based on the Brazilian Dietary Guidelines (BDG) diet and the EAT-Lancet diet) versus the CBD. The DIETCOST program generated multiple food baskets for each scenario (Montecarlo simulations). Nutritional quality, cost, and environmental impact measures (carbon footprint (CF) and water footprint (WF)) were estimated for all diets and compared by ANOVA. Simple linear regressions used standardized environmental impacts measures to estimate differentials in costs and environmental impacts among diets scenarios. RESULTS: We observed significant differences in costs/1000 kcal. The BDG diet was cheaper (BRL$4.9 (95%IC:4.8;4.9) ≈ USD$1.5) than the CBD (BRL$5.6 (95%IC:5.6;5.7) ≈ USD$1.8) and the EAT-Lancet diet (BRL$6.1 (95%IC:6.0;6.1) ≈ USD$1.9). Ultra-processed foods (UPF) and red meat contributed the most to the CBD cost/1000 kcal, while fruits and vegetables made the lowest contribution to CBD. Red meat, sugary drinks, and UPF were the main contributors to the environmental impacts of the CBD. The environmental impact/1000 kcal of the CBD was nearly double (CF:3.1 kg(95%IC: 3.0;3.1); WF:2,705 L 95%IC:2,671;2,739)) the cost of the BDG diet (CF:1.4 kg (95%IC:1.4;1.4); WF:1,542 L (95%IC:1,524;1,561)) and EAT-Lancet diet (CF:1.1 kg (95%IC:1.0;1.1); WF:1,448 L (95%IC:1,428;1,469)). A one standard deviation increase in standardized CF corresponded to an increase of BRL$0.48 in the cost of the CBD, similar to standardized WF (BRL$0.56). A similar relationship between the environmental impact and the cost of the BDG (CF: BRL$0.20; WF: BRL$0.33) and EAT-Lancet (CF: BRL$0.04; WF: BRL$0.18) was found, but with a less pronounced effect. CONCLUSIONS: The BDG diet was cost-effective, while the EAT-Lancet diet was slightly pricier than the CBD. The CBD presented almost double the CF and WF compared to the BDG and EAT-Lancet diets. The lower cost in each diet was associated with lower environmental impact, particularly for the BDG and EAT-Lancet diets. Multisectoral public policies must be applied to guide individuals and societies towards healthier and more sustainable eating patterns.

RESUMEN

Inadequate practices during complementary feeding are associated with malnutrition, especially in children experiencing vulnerable conditions and social inequality. The aim of this study was to evaluate the trends in complementary feeding indicators (CFIs) according to participation in a Brazilian cash transferu program-the Bolsa Família Program (BFP). This was a time-series study with secondary data from 600,138 children assisted from 2015 to 2019 and registered within the Brazilian Food and Nutrition Surveillance System. The CFIs assessed were food introduction, minimum meal frequency and appropriate consistency, minimum dietary diversity, iron-rich food, vitamin A-rich food, ultra-processed food consumption, and zero vegetable or fruit consumption. Prevalence and 95% confidence intervals were calculated for the CFIs according to BFP, the region of residence, and the child's age. The Prais-Winsten regression method was used to analyze the temporal trend. There was a steady trend for all CFIs of a healthy diet. A decrease in ultra-processed food consumption for both BFP (-10.02%) and non-BFP children (-9.34%) was observed over the years. Children residing in the North and Northeast regions and those enrolled in the BFP were more distant from the recommended feeding practices when compared to the other regions and non-BFP children. The results highlight the relevance of nutritional surveillance and the need to improve food and nutrition public policies for children aged 6-23 months, particularly for those experiencing greater social vulnerability.

RESUMEN

OBJECTIVE: To evaluate differences in the percentage of expenditure on food groups in Mexican households according to the gender of the household head and the size of the locality. DESIGN: Analysis of secondary data from the National Household Income and Expenditure Survey (ENIGH) 2018. We estimated the percentage of expenditure on fifteen food groups according to the gender of the head of household and locality size and evaluated the differences using a two-part model approach. SETTING: Mexico, 2018. PARTICIPANTS: A nationally representative sample of 74 647 Mexican households. RESULTS: Female-headed households allocated a lower share of expenditure to the purchase of sweetened beverages and alcoholic beverages and higher percentages to milk and dairy, fruits and water. In comparison with metropolitan households, households in rural and urban localities spent more on cereals and tubers, sugar and honey, oil and fat and less on food away from home. CONCLUSIONS: Households allocate different percentages of expenditure to diverse food groups according to the gender of the head of the household and the size of the locality where they are located. Future research should focus on understanding the economic and social disparities related to differences in food expenditure, including the gender perspective.

RESUMEN

PURPOSE: This study aimed to estimate the health, economic, and environmental impacts of moderate simulated interventions on dietary intake in Brazil. METHODS: Data on food price and consumption were obtained from three nationwide surveys. Baseline dietary intake was estimated for 33,859 individuals aged 25 years and older. Counterfactual intakes were based on six hypothetical intervention scenarios, by changing the weekly frequency and serving size in low or high consumers of fruit and vegetables (FV), milk, whole grains, red and processed meats, and sugar-sweetened beverages. For each scenario, we estimated the attributable number of deaths and disability-adjusted life years (DALY), monetary cost, environmental impacts (14 midpoint indicators), and environmentally-mediated health impacts. RESULTS: Compared with the baseline intake and cost, the most expensive intervention (+ 8.3%) was to increase FV intake (+ 125 g), resulting in a 1.2% reduction in all-cause mortality (16,307 deaths/year). The cheapest (- 9.9%) was to reduce red and processed meat intake (- 40 g), resulting in a 1.1% reduction in all-cause mortality (14,272 deaths/year). The combined intervention was, on average, 3.7% cheaper than the baseline cost, resulting in an increase in diet cost for 30% of the population (45-22% in the lower- and higher-income groups); all-cause mortality would be reduced by 3.8% (49,488 deaths/year). Interventions targeting red and processed meats would reduce emissions and resource use by 35-55%, in addition to reducing 2300 DALYs/year. CONCLUSION: A meaningful number of deaths can be avoided and environmental impacts reduced through moderate and potentially affordable diet modifications.

RESUMEN

Introdução: Ter uma alimentação adequada e saudável envolve diferentes aspectos, entre os quais o custo é um dos principais determinantes. Objetivo: Investigar os custos da alimentação em amostra representativa da população residente no município de São Paulo em 2003, 2008 e 2015. Métodos: Foram utilizados dados do estudo transversal, base populacional, ISA-Nutrição, com residentes no município de São Paulo. Dados socioeconômicos e estilo de vida foram coletados em visitas domiciliares e inquérito telefônico e, consumo alimentar, por dois recordatórios de 24 horas. Para avaliação da qualidade e classificação da dieta foram utilizados: Índice de Qualidade da Dieta Revisado - IQD-R, grupos de alimentos de proteção ou de risco para doenças cardiometabólicas baseados na classificação What we eat in América? (WEEIA), adaptada para América Latina e análise da aderência às recomendações da Organização Mundial da Saúde (OMS) quanto ao consumo de frutas, verduras e legumes, açúcar, sódio e gordura saturada. A estimativa de custos da alimentação foi baseada em preços dos alimentos das Pesquisas de Orçamento Familiar (POF) do Instituto Brasileiro de Geografia e Estatística (IBGE), sendo adotados critérios definidos de pareamento para linkage (ano de estudo, renda familiar per capita, perfil familiar), incluindo, aplicação de fatores de cocção e conversão, assim como uso de deflatores para comparação entre diferentes períodos. Elasticidades da demanda por alimentos foram analisadas utilizando-se regressão log-linear (endogeneidade/teste Durbin-Wu-Hausman). Associação entre custo e qualidade da dieta foi avaliada por meio de custo-efetividade/incremental. Resultados: De 2003 a 2015, houve aumento nos preços por caloria de cereais integrais e carne vermelha. Por outro lado, queda para frutas, verduras/legumes, feijão, leguminosas, oleaginosas/sementes e peixes/frutos do mar. Elasticidades-preço destes grupos de alimentos apresentaram coeficientes negativos, mostrando tendência de redução do consumo devido ao aumento dos preços. Cereais integrais mostraram complementaridade com oleaginosas e sementes, enquanto verduras/legumes, complementaridade com carnes processadas em 2003 e 2015, e oleaginosas/sementes em 2008 e 2015. Frutas e bebidas açucaradas apresentaram relação de substituição. Em 2015, dietas que apresentaram maior aderência às recomendações dietéticas (IQD-R - maiores pontuações) possuíam maior custo. No entanto, maior aderência às recomendações da Organização Mundial da Saúde (OMS) quanto ao consumo de frutas, verduras/legumes, sódio, açúcares e gordura saturada representou menor custo. Indivíduos que compraram alimentos em feiras livres tiveram menor custo da dieta e aqueles com renda inferior a um salário-mínimo comprometem quase totalidade do orçamento familiar com alimentação (99,49%). Verifica-se maior participação no custo da dieta, do grupo das carnes, independente da qualidade da dieta. Conclusões: O método linkage constituiu-se um recurso importante para avaliação do custo das dietas em estudos em que estas informações estão ausentes. Devido à alta elasticidade-preço no período avaliado (12 anos), consumidores do município de São Paulo responderam ao aumento dos preços com redução do consumo. Grandes mudanças nos preços relativos de bebidas açucaradas deveriam ser necessárias para reduzir seu consumo, com possibilidade de substituição às frutas. Impostos para carnes ou subsídios para legumes e verduras devem considerar potenciais efeitos cruzados. Por outro lado, subsídios, aos cereais integrais, beneficiaria o consumo de oleaginosas e sementes. Maior custo de dietas apresentou maior aderência às recomendações dietéticas e local de compra de alimentos (feiras livres) melhoria na qualidade nutricional da dieta com menor custo.


Introduction: Having an adequate and healthy diet involves different aspects, among which cost is one of the main determinants. Objective: To investigate the costs of food in a representative sample of the population living in São Paulo in samples from the years 2003, 2008 and 2015. Methods: We used data from the cross-sectional, population-based study, ISA-Nutrition, with residents in the municipality of São Paulo in 2003, 2008, and 2015. Socioeconomic and lifestyle data were collected in home visits and telephone survey and, food intake, by two 24-hour recall. To evaluate the quality and classification of diet, we used: the Brazilian Health Eating Index - Revised (BHEI-R); protection or risk groups for cardiometabolic diseases based on the "What we eat in America?" (WEEIA) classification, adapted for Latin America and analysis of adherence to World Health Organization (WHO) recommendations for fruit and vegetable consumption, sugar, sodium, and saturated fat. The estimation of food costs was based on food prices from the Household Budget Surveys (HBS) of the Brazilian Institute of Geography and Statistics (IBGE), adopting well-defined pairing criteria for linkage (year of study, per capita family income, family profile), including the application of cooking and conversion factors, as well as the use of deflators for comparison between different periods. Food demand elasticities were analyzed using log-linear regression (endogeneity/Durbin-Wu-Hausman test). Association between cost and diet quality was assessed using cost-effectiveness/incremental. Results: From 2003 to 2015, there was an increase in prices per calorie for whole grains and red meat. On the other hand, declines for fruits, vegetables/legumes, beans, legumes, oilseeds/seeds, and fish/seafood. The price elasticities of these food groups showed negative coefficients, showing a tendency of consumption to decrease due to price increases. Whole grains showed complementarity with oilseeds and seeds, while vegetables/legumes, complementarity with processed meats in 2003 and 2015, and oilseeds/seeds in 2008 and 2015. Fruits and sugar-sweetened beverages showed a substitution relationship. In 2015, diets that showed higher adherence to dietary recommendations (BHEI-R - higher scores) had higher cost. However, higher adherence to World Health Organization (WHO) recommendations for fruit, vegetable intake, sodium, sugars, and saturated fat represented lower cost. Individuals who bought food at street markets had lower dietary costs and those with incomes below one minimum wage spent almost the entire family budget on food (99.49%). There was a greater participation of the meat group in the cost of the diet, regardless of the quality of the diet. Conclusions: The linkage method can be an important resource for evaluating the cost of diets in studies where this information is absent. Due to the high price elasticity over the evaluated period (12 years), consumers in São Paulo responded to price increases by reducing consumption. Large changes in the relative prices of sugar-sweetened beverages would be necessary to reduce their consumption, with the possibility of substitution to fruit. Taxes for meat or subsidies for vegetables should consider potential cross effects. Subsidies, to whole grains, would benefit the consumption of oilseeds and seeds. Higher cost of diets showed greater adherence to dietary recommendations and location of food purchase (street markets) improved nutritional diet quality at lower cost.

RESUMEN

Spineless cactus (Nopalea cochenillifera) is widely used in animal feed in semi-arid regions, due to the adaptive characteristics to such conditions and for having high levels of soluble carbohydrates. This research article describes the effect of replacing grain maize with spineless cactus in the diet of dairy goats on dry matter intake, water intake, milk yield, milk physicochemical characteristics and diet production costs. Eight multiparous Anglo Nubian goats were fed diets in which grain maize was replaced with spineless cactus at four levels (0, 33, 66, and 100%) in a double 4 × 4 Latin square design. Milk yield was measured and samples collected in the last three days of each period for physicochemical analysis and for determining nutrient intake. Diet production costs were also determined. Replacing maize with spineless cactus did not influence dry matter intake. Water intake via the drinker decreased linearly in response to the increasing levels of spineless cactus in the diet. The replacement of maize with spineless cactus did not change milk yield or physicochemical parameters. Total feed cost and the percentage of revenue losses from feed decreased with the replacement. Therefore, spineless cactus can fully replace grain maize in the diet of dairy goats, as it does not change dry matter intake or milk yield, but rather reduces feed costs and the drinking-water intake of goats.

RESUMEN

The present study aimed to obtain, through statistical methods, the independent variables that influence the economic and productive results of Brazilian beef cattle. Economic and productive information was collected from 106 farms in Brazil. Data collection was performed by the Instituto de Métricas Agropecuárias (Inttegra). The variable selection method used was stepwise regression followed by polynomial regression analyses. The variable beef cattle economic result showed the positive effect of disbursement per head per month and average weight gain. An average daily gain of 520 g in live weight was obtained, and this variable was influenced especially by nutrition cost. The arroba production (arroba is a unit of weight corresponding to 15kg) was influenced by the linear effect of nutrition cost and stocking rate. The variable arroba production in pasture showed a linear and positive effect of average weight gain in pasture and stocking rate in pasture. For profit per arroba, the variables nutrition cost, disbursement with pasture, and average sale price had a linear effect. The independent variables that had the greatest influence on the response variables were stocking rate, average daily weight gain, and nutrition cost. Thus, increases in investment in nutrition and stocking rate should result in higher production rates and improvements in the profitability of this activity.(AU)


O presente trabalho teve como objetivo obter, por meio de métodos estatísticos, quais variáveis independentes influenciam as variáveis econômicas e produtivas na bovinocultura de corte brasileira. O banco de dados utilizado foi obtido por coleta de informações econômicas e produtivas em 106 fazendas no Brasil. O método de coleta de dados foi definido pelo Instituto de Métricas Agropecuárias (Inttegra). Foram realizadas análises de seleção de variáveis pelo método Stepwise, seguido por análises de regressão múltipla. A variável resultado econômico da bovinocultura de corte teve efeito positivo do desembolso mensal por cabeça e do ganho de peso médio diário. Para o ganho de peso médio diário foi obtido um valor médio de 520 gramas, e esta variável foi influenciada principalmente pelo custeio com nutrição. Para a produção de arroba foi obtido efeito linear do custeio com nutrição e da taxa de lotação. Para a variável produção de arroba a pasto foi obtido um efeito linear e positivo do ganho médio diário de peso no pasto e da taxa de lotação no pasto. Para o lucro por arroba, as variáveis custeio com nutrição, desembolso com pastagem e preço médio de venda tiveram efeito linear. As variáveis independentes que tiveram maior influência nas variáveis resposta foram a taxa de lotação, o ganho médio diário de peso e o custeio com nutrição. Assim, aumentos no investimento em nutrição e na taxa de lotação dos animais devem resultar em maiores índices de produção e em melhorias na rentabilidade da atividade.(AU)

RESUMEN

The work assessed the productive response and estimated enteric methane (CH4) emissions of dairy cows grazing in small-scale dairy systems. Treatments were grazing annual pasture (AP) mainly of annual ryegrass and perennial pasture (PP) mainly of perennial ryegrass, complemented daily with 3.72 kg DM/cow of commercial concentrate. Eight Holstein cows were used in a double cross-over design with three 14-day-each experimental periods for animal variables and CH4 emissions. Pasture variables were analysed with a split-plot design. AP showed higher sward height (P < 0.05) with no differences (P > 0.05) in net herbage accumulation or in herbage chemical composition. Cows on AP yielded 24.6% more milk (P < 0.001) than grazing PP, but there were no differences in milk fat and protein content. There were differences (P ≤ 0.05) among periods for milk yields, but no differences among periods for milk fat and protein. Milk urea nitrogen was significantly higher (P < 0.001) in PP than in AP with no differences among periods. There was higher (P < 0.001) DMI for AP than PP with a significant decline (P < 0.05) as periods progressed. There was a trend (P = 0.08) for higher daily CH4/cow in AP, but significantly lower emissions (7.2%) in AP/kg DMI, and 20.1% lower emission intensity of g CH4/kg milk. The proportion of gross energy lost as CH4 for AP was lower (P < 0.01). Higher milk yields in AP resulted in a 26% higher margin over feed costs than for PP. Results show that grazing annual pastures with moderate concentrate supplementation results in higher milk yields, higher incomes, and reduces the intensity of CH4 emissions.

RESUMEN

The present study aimed to verify and compare the costs of homemade diets with extruded and wet commercial diets for dogs in maintenance and consuming therapeutic diets (obesity, congestive heart failure, diabetes, hepatic encephalopathy, chronic kidney disease, and food hypersensitivity), which is important information that impacts in the choice of food by the owners. The maintenance energy requirements (MER) were estimated for adult dogs of different sizes (3 kg, 15 kg, 30 kg, and 50 kg) and the daily amounts of food intake were estimated for each type of food. The costs were calculated per day, per 1000 kcal of metabolizable energy of product and per kg of metabolic weight of the animal. Fourteen complete and balanced homemade diets were formulated, and in each proposed group, two diets with different protein sources were used. Under the conditions of the present study, it was possible to conclude that homemade diets were more expensive than dry maintenance diets and dry therapeutic diets, while commercial wet diets were more expensive in all of the scenarios.

RESUMEN

The present study aimed to examine the nutritional deprivation of Paraguayan households (measured as households' access to diverse diets) and investigate the association between nutritional deprivation and socio-economic characteristics in a large sample. An extension of Alkire-Foster methodology, a technique widely employed in multidimensional poverty measurement, was used to calculate both the incidence and intensity of nutritional deprivation. The resulting Nutritional Deprivation Index allows us to consider minimum food group requirements that vary by food groups as well as by individual characteristics such as age, sex and activity level. Applying the methodology to a nationally representative sample of households from the 2011-2012 Income and Expenditures Household Survey, the study found that about two in every three Paraguayan households (67 %) were inadequately nourished in at least four (of the total of six) food groups. Although no significant differences were found between rural and urban households, the incidence of multi-dimensionally deprived households generally decreased as income increased. Logistic regression results showed that nutritional deprivation decreased as household income and mother's education increased and increased with household size. Our study concludes that the majority of Paraguayan households is significantly nutritionally deprived across most food groups and suggests that strategies are needed to improve their access to diverse diets, especially among its lower- and middle-income segments.

RESUMEN

This study aimed to evaluate different scenarios (year, supplementation level) about economic results of beef cattle production during rearing and finishing phase in Brazilian's tropical pastures. Four scenarios were evaluated in combination with fourteen supplements, and it was originated from some research developed inside Forage Crops and Grasslands section from São Paulo State University among years 2011 and 2014. The economic evaluation was analyzed by operating cost, total operational costs, gross revenue, operating profit, and financial net income. Besides profitability, internal rate of return (IRR), benefit/cost ratio (B:C), and simple payback period (SPP) were calculated too. During rearing phase, the best result was observed for scenario 2 (2012), supplement 3.2 (mineral mix) with values of 11 cycles, 26.3%, 9.30%, and 0.39 for SPP, profitability, IRR, and B:C ratio, respectively. Already to finishing phase, the best scenario was 3 (2013), supplement 10 (multiple supplement with supplementation level equal 1.0% body weight), which obtained 4 cycles, 68.7%, 27.00%, and 2.34 for the same variables above mentioned. Results were consistent being that higher IRR and profitability occurred when using low supplementation level. Hence, the economic responses from different scenarios (years and supplements) can alter the final livestock farm financial statement.

RESUMEN

OBJECTIVE: To identify food choices allowing the fulfillment of nutritionally adequate diets resembling actual food patterns at the lowest cost achievable for the Brazilian population, stratified by income level. METHODS: Food consumption and prices were obtained from the Household Budget Survey (n = 55,970 households) and National Dietary Survey (n = 32,749 individuals). The sample was stratified into capitals of the states and further by income levels according to the official minimum wage (totaling 108 geographic-economic strata, or GES). Linear programming models were performed for each GES in order to find the lowest cost of diets that meet a set of nutritional constraints. In order to find realistic diets, constraints referring to preferences were introduced in the models allowing optimized food quantities to depart progressively from the current intake for each food and food group. The impact of meeting each target nutrient was assessed by performing models removing each nutrient at the time. RESULTS: The observed and optimized diet costs were US$2.16 and US$2.58 per capita/day. The highest cost increment and the greatest food shifts were observed in the lowest income level. The nutrient adequacy was reached by mainly increasing fruits and vegetables, beans, fish and seafood, dairy, nuts, and eggs; and reducing red and processed meat, chicken, margarine and butter, cookies, cakes, sugar-sweetened beverages, and sauces. As the departure from the current intakes increase, the optimized healthy diet cost reduced. In the lowest income, the lowest cost increment was about US$ 0.10; in the higher income levels, it tended to be cheaper than the observed cost. Calcium was the most expensive nutrient to meet adequacy. CONCLUSION: Nutritionally adequate diets are possible but costlier than the observed.

RESUMEN

OBJECTIVE: To analyze the consumption of ultra-processed foods in the Colombian population across sociodemographic factors. METHODS: We used data from the 2005 National Survey of the Nutritional Status in Colombia. Food consumption was assessed using a 24-hour food recall in 38,643 individuals. The food items were classified according to the degree and extent of industrial processing using the NOVA classification. RESULTS: The mean calorie contribution of ultra-processed foods ranged from 0.2% in the lowest quintile of consumers to 41.1% in the highest quintile of consumers. The greatest increases were due to the consumption of industrialized breads, sweet and savory snacks, sugary drinks, processed meats, and confectionery. No major differences were found in the consumption of ultra-processed foods between men and women. We observed significant differences by age, socioeconomic status, area of residence, and geographic region. Children and adolescents showed a higher intake of ultra-processed foods, almost double that of participants over 50 years of age. Children consumed significantly more snacks, confectionery products, processed cereals, milk-based drinks and desserts. Participants over 50 years consumed fewer products from these sub-groups of ultra-processed foods but had the highest consumption of industrialized bread. Individuals from urban areas, those with high socioeconomic status, participants residing in the Bogotá region had 1.5 to 1.7 times higher calorie intake from ultra-processed foods compared with those from a lower socioeconomic status and those residing in rural regions. CONCLUSION: In Colombia, industrialized bread is the ultra-processed product that is most easily assimilated into the traditional diet, along with snacks and sugary drinks. Children and adolescents residing in urban areas and households with greater purchasing power have some of the highest intakes of ultra-processed foods in the country.

RESUMEN

Nutrition transition theory describes a progressive substitution of local staples for industrialized processed foods in local diets, a process documented diversely across world regions, and increasingly observed in rural areas of the global south. Here we examine the role of conditional cash transfer programs, in particular the emblematic Brazilian Bolsa Família (BFP), in driving nutritional transition in rural areas of the Amazon. Based on ethnographic research with both participating and nonparticipating women in the Amanã Sustainable Development Reserve (SDR), our analysis integrates Food Frequency Questionnaires (FFQ), seasonal 24-hour food intake recalls, and stable isotope ratios in fingernails to examine dietary behavioral change. Contrary to dietary changes observed elsewhere in the Amazon, participation in the BFP is not associated with a significant substitution of local staples for industrialized processed foods in Amanã. While an increase in the consumption of some industrialized foods was observed, it has been selective and it has not changed the structure of diets. Factors such as social and cultural value of local staples, resident's involvement with the SDR, their relationship with lake and upland forest and agricultural environments, and limited market access have buffered the expansion of industrialized processed foods as observed elsewhere.

RESUMEN OBJETIVO Analizar el consumo de alimentos ultraprocessados en la población colombiana según factores sociodemográficos. MÉTODOS Se usaron datos de la Encuesta Nacional de la Situación Nutricional en Colombia del año 2005. El consumo de alimentos se evaluó por medio de recordatorio 24 horas en 38.643 individuos. Los ítems alimentarios se clasificaron según el grado y extensión de procesamiento industrial usando la propuesta NOVA. RESULTADOS La contribución promedio de calorías de los alimentos ultraprocesados varió del 0,2% en el primer quintil al 41,1% en el ultimo quintil. Los mayores incrementos se dieron por el consumo de panes industrializados, snacks dulces y salados, las bebidas azucaradas, las carnes procesadas y los productos de confitería. No hubo grandes diferencias en el consumo de alimentos ultraprocesados entre hombres y mujeres. Se observaron diferencias significativas por edad, estatus socioeconómico, área de residencia y región geográfica. Los niños y adolescentes presentaron mayor ingesta de alimentos ultraprocesados, casi el doble que los participantes mayores de 50 años. Los niños consumieron significativamente mayor cantidad de snacks, productos de confitería, cereales procesados, bebidas a base de leche y postres. Mientras que los participantes mayores de 50 años consumieron menor cantidad de productos de estos subgrupos de alimentos ultraprocesados, pero tenían el consumo más alto de pan industrializado. Los habitantes urbanos, con alto estatus socioeconómico, que residían en la región de Bogotá tenían entre 1,5 a 1,7 más veces de ingesta calórica de alimentos ultraprocesados en comparación con sus contrapartes de bajo estatus socioeconómico, y sus contrapartes rurales. CONCLUSIÓN En Colombia, el pan industrializado es el alimento ultraprocesado más fácilmente asimilable en la dieta tradicional, junto con los snacks y las bebidas azucaradas. Los niños y adolescentes residentes en zonas urbanas y hogares con mayor poder adquisitivo fueron más vulnerables en el consumo de alimentos ultraprocesados.

RESUMEN

The environment and the socioeconomic level are determinants of eating behavior because they affect availability, accessibility and food preferences. In order to describe the apparent consumption of food and the availability of energy and nutrients in urban and rural households in Argentina according to their income level, the 2004-2005 National Household Expenditure Survey was analyzed. The average apparent consumption of food and beverages was calculated in grams or milliliters of net weight per adult equivalent per day, for urban and rural households, and by household income per capita quintiles. Rural households made up 7% of the sample, and had a higher proportion of low-income families than urban households. There is different pattern of apparent consumption of food and beverages among rural and urban households in Argentina, and there are also differences between households according to the level of income in both environments. Knowing the content and magnitude of these contrasts is of great use in looking for strategies to improve the population's diet.


El entorno y el nivel socioeconómico son determinantes del comportamiento alimentario porque inciden en la disponibilidad, la accesibilidad y las preferencias alimentarias. Con el objetivo de describir el consumo aparente de alimentos y la disponibilidad de energía y nutrientes de hogares urbanos y rurales de la Argentina, según su nivel de ingresos, se analizó la Encuesta Nacional de Gastos de los Hogares 2004-2005. Se calculó el consumo aparente promedio de alimentos y bebidas en gramos o mililitros de peso neto por adulto equivalente por día, de hogares urbanos y rurales, y según quintil de ingresos per cápita del hogar. El 7% fueron hogares rurales, y presentaron mayor proporción de familias con bajos ingresos respecto a los urbanos. Existe un patrón de consumo aparente de alimentos y bebidas distinto entre hogares rurales y urbanos de Argentina, y además existen diferencias entre los hogares según el nivel de ingresos en ambos entornos. Conocer los contrastes y su magnitud es de gran utilidad para buscar estrategias tendientes a mejorar la alimentación de la población.

RESUMEN

Resumo O objetivo deste artigo é avaliar o consumo de produtos ultraprocessados e fatores associados em crianças pré-púberes. Estudo transversal realizado com 378 crianças de 8 e 9 anos matriculadas em escolas públicas e privadas de Viçosa-MG. O consumo alimentar foi avaliado por três recordatórios de 24h. Os dados dietéticos foram tabulados no software Diet Pro® 5i, para quantificar o consumo energético. Para análise dos grupos de consumo alimentar foi utilizada a técnica Two-Step Cluster, por meio do software Stata versão 13.0. Os alimentos foram agrupados e classificados como marcadores de alimentação "saudável" e "não saudável". A associação entre as variáveis sociodemográficas e os grupos formados foi verificada por meio da Regressão de Poisson. Obteve-se a formação de dois grupos alimentares: "saudável" e "não saudável". A ingestão calórica de ultraprocessados foi menor no grupo "saudável" (20,5%) em relação ao "não saudável" (24,1%; P=0,043). No modelo multivariado, crianças de escola privada (RP = 1,25, P<0,001), que não recebiam Bolsa Família (RP=1,13, P=0,036) e cuja mãe trabalhava (RP=1,38, P<0,001) apresentaram maior chance de consumo "não saudável". O consumo de produtos ultraprocessados associou-se ao maior poder aquisitivo das famílias de crianças pré-púberes.


Abstract The aim of this study was to evaluate the intake of ultra-processed foods and associated factors in prepubertal children. It is a cross-sectional study with 378 children aged 8 and 9 years enrolled in public and private schools in Viçosa-MG. Food intake was assessed by three 24-hour dietary recalls. Dietary data were entered into the Diet Pro® 5i software to quantify energy intake. The Two-Step Cluster technique was used to analyze food consumption groups, with the Stata 13 software package. The foods were grouped and classified as "healthy" and "unhealthy" eating markers. The association between the sociodemographic variables and the groups formed was examined by Poisson Regression. Two food groups were formed: "healthy" and "unhealthy". The caloric intake of ultra-processed foods was lower in the "healthy" group (20.5%) than in the "unhealthy" group (24.1%; P = 0.043). The multivariate model showed that private school children (PR = 1.25, P <0.001), who did not receive Bolsa Familia (PR = 1.13, P = 0.036) and had working mothers (PR = 1.38, P <0.001) had increased probability of unhealthy food consumption. Ultra-processed food intake was associated with greater purchasing power of families of prepubertal children.
