Avaliação do microambiente alimentar em estabelecimentos fornecedores de alimentos em um município do trairí do Rio Grande do Norte / Evaluation of the food microenvironment in establishments supplying foods in acity of Trairi ofRio Grande do Norte / Evaluación del microambiente alimentario en provedores de alimentos en unmunicipio de Trairi doRio Grande do Norte

Introdução:As pessoas passaram a consumir alimentos prontos e ultraprocessados cada vez mais e diminuíram o consumo de alimentos naturais. Consequentemente, têm aumentado o desenvolvimento de obesidade e outras doenças crônicas não transmissíveis. Esse processo de transição nutricional e epidemiológico tem sido influenciado pelo ambiente alimentar. Objetivo:avaliar o microambiente alimentar em mercados e restaurantes do município de Santa Cruz, Rio Grande do Norte. Metodologia:Trata-se deuma pesquisa transversal e descritiva, de abordagem quantitativa, realizada em 60 estabelecimentos comerciais fornecedores de alimentos naturais, industrializados e refeições prontas. Foram aplicados questionários, de acordo com a classificação do tipo deestabelecimento para verificação da disponibilidade, variedade, preço e qualidade de alimentos naturais e ultraprocessados. Resultados:A maior parte dos estabelecimentos participantes eram mercados locais ou de bairros, localizados no centro da cidade, evidenciando as desigualdades territoriais.Foi visto que a disponibilidade de frutas e hortaliças era inferior aos ultraprocessados. Os alimentos apresentaram qualidade satisfatória e os menores preços de frutas foram encontrados nos supermercados e mercadinhos, enquanto os das hortaliças na feira livre. Conclusões:ficou evidente a necessidade de políticas públicas de incentivo a descentralização do comércio de alimentos e o incentivo à venda de alimentos mais saudáveis e acessíveis física e financeiramente (AU).

Introduction:People have started to consume more and more ready-to-eat foods and have reduced their consumption of fruit and vegetables. Consequently, the prevalence of overweight and chronic non-communicable diseases have increased over the years. This dietary and epidemiological transition process has been influenced by the food environment in which they are inserted. Objective:to evaluate the food microenvironment in markets and restaurants in the city of Santa Cruz, Rio Grande do Norte.Methodology:This is a cross-sectional and descriptive research, with a quantitative approach, carried out in 60 commercial establishments supplying natural and processed foods and ready-to-eat meals. Questionnaires were applied, according to the classification of the type of establishment, to check the availability, variety, price and quality of natural and ultra-processed foods.Results:Most of the participating establishments were local or neighborhood markets,located in the downtown, highlighting territorial inequalities. It was noted that the availability of fruits and vegetables is lower than the ultra-processed foods. All foods showed satisfactory quality, and the lowest prices for fruits were found in supermarkets and grocery stores, while vegetables were found in the street market. Conclusions:the need for public policies to encourage the decentralization of the food trade and the incentive to sell healthier and more affordable foodsphysically and financially became evident (AU).

Cost of healthy and culturally acceptable diets in Brazil in 2009 and 2018 / Custo de uma alimentação saudável e culturalmente aceitável no Brasil em 2009 e 2018

ABSTRACT OBJECTIVE To estimate the lowest cost of a healthy and culturally acceptable diet and to assess the evolution of its cost in the periods 2008-2009 and 2017-2018. METHODS We used data on the individual food consumption and food prices from the Pesquisas de Orçamentos Familiares (Household Budget Surveys), in the 2008-2009 and 2017-2018. The sample strata of each period were aggregated, forming 108 new strata with geographic and economic homogeneity. Linear programming models generated diets for each new stratum, considering the constraints in two models: model 1 (≥ 400g of fruits and vegetables); and model 2 (≥ 400g of fruits and vegetables, < 2300mg of sodium, sodium/potassium ratio < 1, ≥ 500mg of calcium). Each food could progressively deviate 5g from the observed consumption averages until the models found a solution in each of the strata. The objective function was to minimize the total cost of the diet. RESULTS The average observed and optimized costs were R$4.96, R$4.62 (model 1) and R$5.08 (model 2) in 2008-2009, and R$9.18, R$8.69 and R$9.87 in 2017-2018. Models 1 and 2 resulted in an increase of up to 6% and 11% in 2008-2009, and of up to 25% and 34% in 2017-2018 in the lowest income strata. The main changes observed in the two models include the reduction in the amounts of sweetened beverages, sweets, sauces, ready-to-eat foods, and an increase in fruits and vegetables, flour, and tubers. CONCLUSION The adequate amount of fruits and vegetables resulted in an increase in costs to some population strata. When the adequacy of calcium, sodium, and potassium was considered, we observed a more significant increase in cost, especially in 2017-2018.

RESUMO OBJETIVO Estimar o menor custo de uma alimentação saudável e culturalmente aceitável e avaliar a evolução de seu custo nos períodos de 2008-2009 e 2017-2018. MÉTODOS Foram utilizados dados de consumo individual dos módulos de consumo alimentar das Pesquisas de Orçamentos Familiares de 2008-2009 e 2017-2018. Os preços dos alimentos foram obtidos do módulo de caderneta de despesa das respectivas pesquisas. Os estratos amostrais de cada período foram reagrupados, formando 108 novos estratos com homogeneidade geográfica e econômica. Modelos de programação linear foram elaborados para gerar dietas para cada novo estrato, considerando as restrições do modelo 1 (≥ 400g de frutas e hortaliças) e modelo 2 (≥ 400g de frutas e hortaliças, < 2300mg de sódio, relação sódio/potássio < 1, ≥ 500mg de cálcio). Cada alimento das dietas observadas poderia desviar progressivamente em 5g a partir das médias de consumo observadas até que os modelos encontrassem uma solução em cada um dos estratos. A função objetivo foi de minimizar o custo total da dieta. RESULTADOS Os custos médios observados e otimizados foram de R$4,96, R$4,62 (modelo 1) e R$5,08 (modelo 2) em 2008-2009 e de R$9,18, R$8,69 e R$9,87 em 2017 -2018. Nos modelos 1 e 2 ocorreram incrementos de até 6% e 11% em 2008-2009 e de até 25% e 34% em 2017-2018 na menor faixa de renda. As principais modificações observadas nos dois modelos incluem a redução nas quantidades de bebidas adoçadas, doces, molhos, alimentos prontos para consumo e aumento de frutas e hortaliças, farinhas e tubérculos. CONCLUSÃO A adequação da quantidade de frutas e hortaliças acarretou aumento no custo para parte da população. Quando a adequação de cálcio, sódio e potássio foram consideradas, ocorreu um aumento mais expressivo no custo, especialmente em 2017-2018.

Effect of Fruit Juices and Other Beverages on Loss of Tooth Structure

Objective: To determine the effect of seven different beverages on tooth enamel. Material and Methods: Human teeth samples were immersed in each beverage (Pepsi, Red Bull, Orange juice, Apple juice, Lemon juice, Coffee and Green tea). Specimens were divided into seven groups by beverage type (n = 5 per group). Weight of the enamel was measured before and after immersion in different beverages daily for at periodic intervals of 24hrs, 7 days, 15 days and 30 days. The data were recorded after weighing the teeth at each time. The beverages were replaced daily. Anova and Tukey post hoc test was performed to compare the differences in percent weight loss. The significance level was set at 5%. Results: There was change in the mean percent weight loss amongst the different beverages with orange juice showing a high reduction in comparison to green tea and coffee. The mean weight reduction of orange juice was by 21% followed by Red Bull (13%), Pepsi (11%), Lemon juice (16%), Apple juice (16%), coffee (3%) and green tea (3%). Conclusion: This study shows that different beverages have erosive potential on teeth depending on the duration of the exposure.

Mechanical properties of composites as functions of the syringe storage temperature and energy dose

Objective: To investigate the mechanical properties of different classifications of composites indicated for posterior application as functions of the storage condition and of the energy dose. Material and Methods: Specimens (8x2x2 mm) were obtained according to the factors: I) Composites (3M ESPE): Filtek P60, Filtek Z350XT, and Filtek Silorane; II) Syringe storage conditions: room temperature, aged, oven, refrigerator, and freezer; and III) Energy dose: 24 J/cm2 and 48 J/cm2. After photoactivation, the specimens were stored at 37ºC for 24 h. After storage, a three-point bending test was carried out in a universal testing machine at 0.5 mm/min. Flexural strength (S) and flexural modulus (E) were calculated. Data were analyzed by three-way ANOVA and Tukey's test (α=0.05). Results: Different storage conditions significantly affected the silorane composite for S; conversely, no effects were noted in terms of E. The accelerated aging protocol significantly increased the S of Filtek P60 and Filtek Silorane, whereas storage in the oven significantly decreased the S for all of the composites tested. Filtek P60 was the only composite not affected by the lower storage temperatures tested for S, whereas for the silorane this parameter was impacted at the same conditions. The factor "dose" was not statistically significant. Conclusions: The syringe storage at different temperature conditions proved to influence mostly the flexural strength, a clinically important characteristic considering the posterior indication of the materials tested. The silorane composite should not be stored at lower temperatures. .

Prevalence of dental erosion among asthmatic patients in India / Prevalência de erosão dentária em pacientes asmáticos na India

OBJETIVOS: O presente estudo foi realizado para investigar a associacao entre erosao dentaria e asma e estabelecer relacao com a historia medica, dieta e nivel de erosao dentaria. MATERIAL E METODO: O estudo transversal foi realizado entre 102 asmaticos e nao asmaticos, com idades entre 18 e 65 anos, em Udaipur, Rajasthan, India, em janeiro de 2009. A erosao dentaria foi determinada pelo uso de index de erosao utilizado em trabalho no Reino Unido em 1993. Os dados foram coletados por meio de questionarios. Os individuos foram examinados utilizando um procedimento do tipo III, por um unico examinador. A variacao intra examinadores foi testada estatisticamente, com acuracia de 90,3%. O teste qui-quadrado foi aplicado com utilizacao do programa SPSS, versao 11.0. RESULTADOS: Erosao dentaria estava presente em 76.5% de adultos com asma e em 66,7% de pacientes sem asma. 86% das drogas prescritas para asma tinham um pH abaixo de 5,5 %. Ocorreu tambem associacao entre erosao dentaria e consumo de refrigerantes, bebidas carbonatadas e frutas frescas. CONCLUSOES: Ha diferenca significativa na prevalencia de erosao, sendo que adultos com asma tem maior prevalencia do que nos grupos controle. Embora ocorra uma relacao entre niveis de erosao, ha tambem relacao dos niveis de erosao relacionadas com a historia medica e componentes acidos da dieta.

OBJECTIVE: This study was done to investigate association between tooth erosion and asthma and to find out the relationship between medical history, dietary practices and the level of dental erosion. MATERIAL AND METHOD: A cross sectional survey was conducted among 102 asthmatic and non asthmatic patient aged from 18 to 65 years old in Udaipur, Rajasthan, in January 2009. Tooth erosion was assessed using tooth erosion index employed in the childrenfs dental health in UK survey 1993. Data was collected by using self-prepared questionnaire. The subjects were examined using a type III examination procedure by single examiner. Intra examiner variability was tested by weighted kappa statistic which was 90.3%. Chi-square test was applied by using SPSS software (version 11.0). RESULTS: Tooth erosion was present in 76.5% of adults with asthma and in 66.7% asthma free subjects. 86% drugs which were prescribed for asthma had a pH below 5.5. There were also association between dental erosion and consumption of soft drinks, carbonated beverages and fresh fruits. CONCLUSION: There was significant difference in prevalence of erosion, adults with asthma having a higher prevalence than controlled group, although there is relationship between levels of erosion, medical history and acidic dietary components.
