Estimación del peso de porciones de alimentos ilustrados en fotografías digitales / Estimation of weight of food portions depicted in digital photographs

Resumen: Objetivo: Evaluar el uso de fotografías digitales para estimar el peso de diferentes preparaciones de alimentos. Metodología: Se compraron 102 platos servidos como almuerzos, desayunos y repostería de 52 establecimientos comerciales en San Pedro de Montes de Oca, se pesaron y fotografiaron los alimentos servidos, resultando un total de 261 porciones de alimentos. Al recibir por correo las imágenes digitales de los platos de comida, se estimó el peso de cada alimento por medio de una comparación con un manual de fotografías estándar. El proceso de pesaje y fotografiado de los alimentos fue realizado de forma independiente del proceso de estimación del peso. Para comparar los pesos reales y los pesos estimados se utilizó la prueba t de Student y coeficientes de correlación. Resultados: Para 6 de los 11 tipos de alimentos, el peso estimado presentado en una imagen digital no fue significativamente diferente al peso real y ambos valores tenían un grado de asociación significativo. En el caso de los otros 5 tipos de alimentos que consistían en preparaciones con un mayor número de ingredientes, hubo diferencias significativas entre los pesos estimados y los pesos reales. Conclusión: En el caso de alimentos simples o con pocos ingredientes, ilustrados en fotografías digitales, su peso se estimó con suficiente exactitud; no así para preparaciones con varios ingredientes. Se requiere más investigación antes de recomendar su uso en encuestas de consumo de alimentos.

Abstract: Objective: To assess the use of digital images for estimating the weight of different portions of foods. Methods: 102 dishes from 52 commercial sites in San Pedro, Montes de Oca, served as lunches, breakfast, and snacks, consisting of a total of 261 portions of foods were purchased, photographed and weighed. On receiving the digital images of the dishes by email, the weights of all the different foods were estimated by using as a comparison, a series of standard photos of foods with known weights. The process of estimating the weights of the foods from the digital images was carried out independently from their being weighed and photographed. A comparison between real and estimated weights was carried out using the Student t test and correlation coefficients. Results: In the case of 6 of the 11 food types, there were no statistically significant difference between real and estimated weights and a significant degree of association was found. Significant differences were observed between real and estimated weights for the remaining 5 foods, which were composed of dishes with a greater number of ingredients and greater variation in proportions of each ingredient. Conclusion: Portion size was estimated with sufficient accuracy for foods prepared from simple recipes with few ingredients, but not for foods prepared with several ingredients. More research is needed before recommending this use of digital images in food consumption surveys.

Capacidad saciante y tamaño de porción para comida y snack en universitarios mexicanos / Satiating capacity and portion size for food and snacks in Mexican university

Un snack es una porción pequeña de alimentos consumida entre comidas principales con el fin de obtener energía. Su presencia en la dieta de adultos ha incrementado en la última década. El objetivo del estudio fue determinar el tamaño de porción ingerida y la percepción de la capacidad saciante esperada (CSE) de diferentes alimentos si son ofrecidos como "comida" o "snack". Se diseñó y validó la encuesta para evaluar las elecciones de tamaño de porción ingerida y la CSE de 12 alimentos seleccionados a través del Análisis Descriptivo Cuantitativo (QDA). Participaron 453 estudiantes de 22±4,0 años, los resultados se evaluaron mediante análisis de varianza (ANOVA) con un nivel de confianza del 95%. En la mayoría de los alimentos (83,3%) la CSE fue mayor cuando eran "snack" que en "comida". El tamaño de porción elegido en 5 alimentos fue menor cuando eran "snack" (p<0,05); para el resto de los alimentos no se mostraron diferencias significativas. Respecto al contenido energético ingerido en los dos tiempos de comida, únicamente dos productos, ampliamente reconocidos como snacks, no presentaron diferencias. La densidad energética ingerida de los alimentos estudiados sería mayor si lo consumieran como comida vs snack (p<0,05). Los resultados concuerdan con la evidencia previa sobre los determinantes para consumo de alimentos: los ingredientes del alimento y su complejidad, la saciedad percibida y sus características orosensoriales. Se puede concluir que el contenido energético y nutrimental no fue tomado en cuenta al elegir la cantidad de alimento independientemente de si se ingiriera en "comida" o "snack"(AU)

'Snack' is a small portion of food consumed between main meals to obtain energy. Its presence in the diet of adults has increased in the last decade. The objective of the study was to determine the size of the ingested portion and the perception of the expected satiating capacity (ESC) of different kinds of food if they are offered as 'meals' or 'snacks'. A survey was conducted to evaluate the ingested portion size choices and the ESC of 12 selected foods through QDA methodology. 453 students aged 22±4.0 years participated in the study, results were analyzed with ANOVA (95% as confidence level). In most of the given choices of food (83.3%) the ESC was greater when they were offered as 'snacks' compared to 'meals'. The portion size chosen for five food options was smaller when they were considered 'snack' (p<0.05); for the rest of the food options, no significant differences were shown. Regarding the energy content ingested at the two mealtimes, only two products, widely recognized as snacks, did not present statistical differences. The consumed energy density of the food choices studied was higher when they were chosen to be consumed as meals vs snacks (p<0.05). The results correspond with previous evidence about the determinants for food consumption: ingredients and complexity of the foods, perceived satiety, and its sensorineural characteristics. It can be concluded that energy and nutritional content was not considered when choosing the amount of food regardless of whether it was ingested as a 'meal' or as 'snack'(AU)

Associations between dietary patterns and metabolic syndrome in adolescents / Asociación entre patrones de alimentación y síndrome metabólico en adolescentes

Abstract: Objective: Evaluate association of dietary patterns with metabolic syndrome (MetS) and metabolic markers. Materials and methods: 654 adolescents from Guadalajara, Jalisco, participated in a cross-sectional study. Diet was evaluated using a food frequency questionnaire; 24 food groups were integrated, and dietary patterns were derived using cluster analysis. MetS was defined according to International Diabetes Federation (IDF), Cook and colleagues, Ford and colleagues, and de Ferranti and colleagues criteria. Results: Dietary patterns identified were: "DP1", "DP2", and "DP3". Among males, "DP3" was associated with MetS (Cook and collaborators) (OR, 12.14; 95%CI, 1.66-89.05), hypertriglyceridemia (OR, 3.89; 95%CI, 1.01-15.07), and insulin resistance (OR, 6.66; 95%CI, 1.12-39.70). "DP2" was associated with abdominal obesity (OR, 5.11; 95%CI, 1.57-16.66). Conclusions: "DP3" entertained a greater risk of MetS, hypertriglyceridemia, and insulin resistance, while "DP2" possessed a greater risk of abdominal obesity among adolescent males.

Resumen: Objetivo: Evaluar la asociación de patrones dietarios (PD) con síndrome metabólico (SM) y marcadores metabólicos. Material y métodos: Estudio transversal con 654 adolescentes. Dieta evaluada con el cuestionario "frecuencia de consumos de alimentos"; se identificaron 24 grupos de alimentos, para obtener PD mediante análisis de conglomerados. SM se definió según los criterios: Federación de Diabetes Internacional (IDF), Cook y colaboradores, Ford y colaboradores y Ferranti y colaboradores. Resultados: Se identificaron tres PD: "PD1", "PD2" y "PD3".

El patrón "PD2" se asoció con obesidad abdominal (RM, 5.11; IC95%, 1.57-16.66). Conclusiones: El patrón "PD3" aumenta el riesgo de SM, hipertrigliceridemia y resistencia a insulina y el "PD2" el riesgo de obesidad abdominal en adolescentes hombres.

Association between ultra-processed food consumption and the nutrient profile of the Colombian diet in 2005 / Asociación entre el consumo de alimentos ultraprocesados y el perfil nutricional de la dieta de los colombianos en 2005

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

Resultados: Los productos de alimentos y bebidas ultraprocesados representaron 15.9% de la ingesta diaria total de energía, en comparación con 63.3% de los alimentos mínimamente procesados, 15.8% de los ingredientes culinarios procesados y 4.9% de los procesados. Los alimentos mínimamente procesados tenían un perfil nutricional más saludable en comparación con los artículos ultraprocesados en términos de contribución a las calorías totales, de proteínas, carbohidratos, grasa total, grasa saturada, azúcar libre, densidad de fibra y densidad de energía. Conclusiones: Los alimentos ultraprocesados tienen un perfil nutricional menos saludable que los alimentos no procesados.

Study on the snack menu pattern, food diversity and satisfaction of parent provided by Center for Children's Foodservice Management in Jeonbuk area / 한국영양학회지

PURPOSE: This study examined the menu pattern, food diversity, and satisfaction of parents with the snack menus of childcare centers provided by the Center for Children's Foodservice Management (CCFM) in Jeonbuk area. METHODS: Data from 2,432 snack menus (1,321 for morning snacks and 1,111 for afternoon snacks) of March, June, September, and December 2017 from 13 CCFM in Jeonbuk area were analyzed. In addition, the participants for the survey were 247 parents in Jeonju and Kunsan. The data were analyzed using a t-test, χ²-test, and hierarchical regression analysis with SPSS v. 24.0. RESULTS: Differences in the menu pattern and food diversity were observed between morning and afternoon snack menus. The majority of snack menus (61.6%) were one menu item. The percentage of ‘G’ (20.0%) was highest in the food group patterns. The morning snacks served mainly porridge, raw fruits, and milk, and the afternoon snacks served mainly flour-based foods, juices, and milk. The awareness level of parents about the snack menus of daycare centers was 4.09±0.82, and its overall satisfaction was 4.06±0.69. In the snack-quality attribute analysis, the hygiene of foods was the most important factor, and parents judged that they were doing well. Regression analysis showed that the hygiene of personnel was the most influential variable on the overall satisfaction, followed by balance with the main meal and the portion size. CONCLUSION: Therefore, it is important to establish snack menu guidelines considering the eating behaviors of the children and to strengthen hygiene for the increasing the satisfaction of various stakeholders in daycare centers.

Students' dietary habits, food service satisfaction, and attitude toward school meals enhance meal consumption in school food service

BACKGROUND/OBJECTIVES: This study aimed to compare student consumption of school meals by school level, to identify the influencing factors of school meal consumption, and to assess improvement needs of school food service among students. SUBJECTS/METHODS: A total of 1,441 elementary, middle, and high school students attending 58 schools in Gyeonggi-do, South Korea participated in the survey in 2015. A questionnaire and informed consent forms for students and legal guardians were sent home and completed responses were returned to the researcher. RESULTS: Approximately 58% of the students perceived the portion sizes of school meals as appropriate and 76.1% consumed almost all or all of the meals served. More elementary and middle school students than high school students consumed almost all or all of the meals (P < 0.001). A regression analysis revealed that the students with a higher dietary behavior score (P < 0.001), higher satisfaction with food service (P < 0.001), a higher environmental protection practice score (P < 0.05), and more positive attitudes toward school meals (P < 0.01) consumed significantly more meals. The provision of foods that taste good and reflecting student opinions on menus were the most important factors for increasing school meal consumption. CONCLUSIONS: To increase consumption of school meals, food service staff should provide students with quality meals and engage students in school food service. Nutrition education that emphasizes healthy eating behaviors and cafeteria environment modification that applies strategies based on behavioral economics can encourage students to consume more school meals.

Gender Perspectives on the Relationship between Red and Processed Meat Intake and Colorectal Cancer: A Systematic Review and Meta-Analysis

BACKGROUND: Men and women choose different food items, and consume different amounts of food, due to biological, cultural, and social differences. However, when dietary assessment instruments are developed, gender differences in food selection and/or the portion sizes are often not considered. METHODS: Prospective cohort studies with men and women that examined the association between red or processed meat intake and colorectal cancer and published up to July 2017, were identified using PubMed. Studies were categorized as gender-specific (GS) group if the Food Frequency Questionnaire was developed using gender-specific data, and as not gender-specific (NGS) group if not gender-specific data were used. RESULTS: For cohort studies that reported combined intake estimates of men and women, a 100 g/day increment in red and processed meat intake was positively associated with a risk of colorectal or colon cancer in GS group (relative risk [RR], 1.23; 95% confidence interval [CI], 1.14–1.32) but not in NGS group (RR, 1.13; 95% CI, 0.90–1.35). For processed meat, the RR for 50 g/day increase was 1.28 (95% CI, 1.15–1.40) in GS group and 1.15 (95% CI, 1.03–1.27) in NGS group. CONCLUSIONS: Gender differences need to be considered during development of dietary assessment tools because this may improve the quality of the findings of nutritional epidemiological studies.

One Menu Please: Parents Want Affordable, Right-sized Portions for Their Children in Restaurants

One contributing factor to the obesity epidemic is the large portion sizes served in restaurants. However, no study has looked at the parents' desire for smaller-portioned meals for their children at restaurants in the U.S. This study examined parents' preference for restaurants to offer smaller, lower-priced child portions for their children and reasons for the preference. Multivariable logistic regression was used to estimate adjusted odds ratios (ORs) for the association between preference for child portions and variables on parental sociodemographic characteristics and weight status. About 70% of parents said they would prefer that restaurants offer smaller, lower-priced child portions of all menu offerings. The adjusted odds of preferring child portions were significantly higher among Hispanic parents (OR, 1.95 vs. non-Hispanic whites) but significantly lower among parents with lower education (≤ high school, OR, 0.64; some college, OR, 0.69 vs. college graduate) and parents residing in the Midwest or West (Midwest, OR, 0.61; West, OR, 0.58 vs. South). The most common reason for preferring child portions of all meals was “wanting my child to eat healthier foods that are not offered on the children's menu” (72%). These findings can be used to encourage restaurants and other venues to consider offering child portions of healthier menu items.

Association between excess weight and beverage portion size consumed in Brazil / Associação entre excesso de peso e tamanho das porções de bebidas consumidas no Brasil

ABSTRACT OBJECTIVE To describe the beverage portion size consumed and to evaluate their association with excess weight in Brazil. METHODS We used data from the National Dietary Survey, which included individuals with two days of food record aged over 20 years (n = 24,527 individuals). The beverages were categorized into six groups: soft drink, 100% fruit juice, fruit drink, alcoholic beverage, milk, and coffee or tea. We estimated the average portion consumed for each group and we evaluated, using linear regression, the association between portion size per group and the variables of age, sex, income, and nutritional status. We tested the association between portion size and excess weight using Poisson regression, adjusted for age, sex, income, and total energy intake. RESULTS The most frequently consumed beverages in Brazil were coffee and tea, followed by 100% fruit juices, soft drinks, and milk. Alcoholic beverages presented the highest average in the portion size consumed, followed by soft drinks, 100% fruit juice, fruit drink, and milk. Portion size showed positive association with excess weight only in the soft drink (PR = 1.19, 95%CI 1.10-1.27) and alcoholic beverage groups (PR = 1.20, 95%CI, 1.11-1.29), regardless of age, sex, income, and total energy intake. CONCLUSIONS Alcoholic beverages and soft drinks presented the highest averages in portion size and positive association with excess weight. Public health interventions should address the issue of portion sizes offered to consumers by discouraging the consumption of large portions, especially sweetened and low nutritional beverages.

RESUMO OBJETIVO Descrever o tamanho das porções de bebidas consumidas e avaliar sua associação com excesso de peso no Brasil. MÉTODOS Utilizou-se dados do Inquérito Nacional de Alimentação, incluindo indivíduos com dois dias de registro alimentar, acima de 20 anos de idade (n = 24.527 indivíduos). As bebidas foram categorizadas em seis grupos: refrigerante; suco; refresco; bebida alcóolica; leite; e café ou chá. Estimou-se a porção média por ocasião de consumo para cada grupo e avaliou-se, por meio de regressão linear, a associação entre tamanho da porção por grupo e as variáveis idade, sexo, renda e estado nutricional. A associação entre tamanho da porção e excesso de peso foi testada por meio de regressão de Poisson, ajustada por idade, sexo, renda e ingestão total de energia. RESULTADOS As bebidas com maior frequência de consumo no Brasil foram café e chá, seguidas dos sucos, refrigerantes e leite. As bebidas alcóolicas apresentaram maior média no tamanho da porção consumida, seguidas dos refrigerantes, sucos, refrescos e leite. O tamanho da porção mostrou associação positiva com excesso de peso somente no grupo dos refrigerantes (RP = 1,19; IC95% 1,10-1,27), e bebidas alcoólicas (RP = 1,20; IC95% 1,11-1,29), independentemente da idade, sexo, renda e ingestão total de energia. CONCLUSÕES Bebidas alcoólicas e refrigerantes apresentaram as maiores médias no tamanho da porção e associação positiva com excesso de peso. Intervenções de saúde pública devem abranger a questão do tamanho das porções oferecidas aos consumidores, desencorajando o consumo de grandes porções, principalmente das bebidas adicionadas de açúcar e de baixo teor nutricional.

Development and relative validity of semi-quantitative food frequency questionnaire for Korean adults / 한국영양학회지

PURPOSE: This study was implemented to develop and validate the semi-quantitative food frequency questionnaire (SQ-FFQ) to assess energy, carbohydrates, fat, protein, minerals, and vitamins as well as fatty acids and alcohol in Korean adults. METHODS: The SQ-FFQ consisted of 88 food items, and 12 food groups were selected based on information of frequently consumed foods from the Korean Health and Nutrition Examination survey. Each portion size was categorized as one of three amounts: small (0.5 times), medium (1 time), and large (1.5 times). A total of 111 subjects finished 3-day diet records and the SQ-FFQ. The relative validity of SQ-FFQ was assessed by comparison with the 3-day diet records. RESULTS: The mean nutrient intakes obtained from the SQ-FFQ were estimated to be greater than those of the two 3-day dietary records. Spearman's correlation coefficient between the two methods was the highest for energy (r = 0.583; p < 0.001) and lowest for saturated fatty acid (r = 0.121). Correlation coefficients were energy (r = 0.583; p < 0.001), carbohydrates (r = 0.500; p < 0.001), protein (r = 0.466; p < 0.001), fat (r = 0.411; p < 0.001), dietary fiber (r = 0.467; p < 0.001), alcohol (r = 0.527; p < 0.001), calcium (r = 0.409; p < 0.001), phosphorus (r = 0.499; p < 0.001), potassium (r = 0.418; p < 0.001), magnesium (r = 0.427; p < 0.001), and zinc (r = 0.464; p < 0.001), respectively, for all subjects. CONCLUSION: The developed SQ-FFQ in this study seems to be useful for estimating nutritional status, particularly energy, carbohydrates, protein, fat, dietary fiber, alcohol, calcium, phosphorus, potassium, magnesium, and zinc of Korean adults.

Comparison Between Semi-Quantitative Frequency Methods and 7-day Dietary Records Methods in Food and Nutrition Intake Status For Hemodialysis Patients / 대한지역사회영양학회지

OBJECTIVES: The valid assessment of food and nutrients intakes using appropriate dietary intake method is necessary to improve the nutritional status of the hemodialysis (HD) patients. This study was conducted to compare the method between newly developed, semi-quantitative food frequency questionnaire (Semi-FFQ) and 7-day dietary records (7-DRs) for hemodialysis patients. METHODS: We conducted both methods on 53 maintenance HD patients in two university hospitals. We calibrated the frequency, portion size and daily intake of 47 food items reported in Semi-FFQ. The food and nutrients intake was compared and the correlation of the two methods was analyzed. Also each nutrient intake was compared to recommended dietary allowance for Korean (KDRIs) and recommended nutrient reference value for HD patients. RESULTS: Energy and energy-yielding nutrients intakes were significantly higher in the two methods (p<0.01). These support the possible reliability between Semi-FFQ and 7-DRs that is similar with regard to most mineral and vitamin intakes. Thus, the Semi-FFQ used in this study for the assessment of nutrient intakes of HD patients can be reliable for the assessment of the nutrient intake along with the 7-DRs. The correlation coefficients were higher for foods consumed daily, such as steamed rice, meat and chicken, bean, egg, milk, coffee and alcohol than for those of foods eaten rarely (p<0.01). CONCLUSIONS: The Semi-FFQ used in this study can be a reliable tool for the assessment of the HD patients' nutrient intake along with the 7-DRs, despite its limitations.

Analysis of factors affecting customer satisfaction of HACCP applied restaurant in highway service area / 한국영양학회지

PURPOSE: The purposes of this study were to investigate food consumption practices and analyze factors that influence customer satisfaction of an HACCP applied restaurant in a highway service area. METHODS: A total of 207 customer responses were used for data analysis. Statistical analyses were conducted using the SPSS program (ver. 22.0) for χ²-test, Pearson correlation analysis, and multiple regression analysis. RESULTS: Reasons for visiting the highway area were using the restroom (86.0%), purchasing of meals or snacks (70.1%), taking a rest (58.5%), and shopping (3.4%) and selection attributes of food sold in the highway service area were food taste (48.8%), food safety (33.3%), and waiting time for meal (10.7%). According to the results of the survey, udon (66.2%) was the most preferred meal, followed by instant noodles (56.0%), kimbap (50.7%), pork cutlet (38.2%), and bibimbap (29.0%). In addition, coffee (73.4%) was the most preferred among snacks and beverages, followed by beverages (58.9%), walnut cake (53.1%), mineral water (52.2%), and hotbar (52.2%). Satisfaction evaluation scores of foods sold in the highway service area were highest for appropriate portion size, followed by food safety, menu variety, food taste, and reasonable price. Overall customer satisfaction scores regarding the restaurant in the highway service area was 3.24 out of 5 points on average. According to the results of the multiple regressing analysis, food taste (p < 0.001) and reasonable price (p < 0.01) had significant positive effects on overall customer satisfaction. CONCLUSION: To enhance customer satisfaction, restaurant managers in the highway service area should implement HACCP, improve food taste, and set up a proper price for food sold at the restaurant in the highway service area.

Validação de fotografias de alimentos para estimativa do consumo alimentar / Validation of food's photographs for estimating the consumption food

RESUMO Objetivo Validar fotografias de um guia fotográfico de alimentos para estimativa do consumo alimentar. Métodos As fotografias de 12 alimentos (bolo simples, macarrão ao sugo, mamão formosa, melancia, repolho roxo ralado, quiabo refogado, churrasco em tiras, filé de frango grelhado, pudim de leite condensado, pizza, amendoim cru e queijo tipo minas), retratadas em três tamanhos de porções (pequena, média e grande), foram avaliadas por 90 indivíduos adultos. Foram também investigados o peso, a estatura e o sexo dos participantes. Para análise de concordância entre o tamanho da porção do alimento retratado nas fotos e o tamanho real do alimento, utilizou-se o teste Kappa. Os dados foram analisados no software Stata, considerando-se p <0,05. Resultados A maior prevalência de acerto foi para as preparações pizza (87,8%), churrasco (80,0%), filé de frango e pudim (75,5%). Já os alimentos com menor percentual de acertos foram a melancia (52,2%), o mamão formosa e o bolo (57,8%). A concordância geral entre a percepção do tamanho da porção do alimento e o tamanho real do alimento foi de 0,622 ( p <0,001). A percepção não foi influenciada pelo sexo e pelo estado nutricional dos participantes ( p >0,05). Conclusão As 12 fotografias apresentaram uma boa concordância com as porções dos alimentos e podem ser um instrumento útil para aumentar a acurácia dos relatos do consumo alimentar.

ABSTRACT Objective Validate photographs of a photographic guide of foods to estimate food consumption. Methods The photos of 12 foods (simple cake, pasta to suck, papaya, watermelon, grated purple cabbage, okra stew, barbecue into strips, grilled chicken, condensed milk pudding, pizza, raw peanuts and cheese type mines), pictured in three portion sizes (small, medium and large), were evaluated for 90 adult subjects. The weight, height and gender of the participants also were investigated. For analysis of agreement between the size of the food portion pictured in the photos and the actual size of the food used the Kappa test. Data were analyzed using Stata software, considering p<0.05. Results The highest prevalence was hit for pizza preparations (87.8%), barbecue (80.0%) chicken fillet and pudding (75.5%), while foods with a lower percentage of correct answers were watermelon (52.2%), the papaya and cake (57.8%). The overall agreement between the perception of the size of the food portion and the actual size of the food was 0.622 (p<0.001). The perception was not influenced by sex and nutritional status of participants (p>0,05). Conclusion We conclude that the 12 photographs showed a good agreement with the portions of food and can be a useful instrument to increase the accuracy of dietary intake reports.

Analysis of Kimchi, vegetable and fruit consumption trends among Korean adults: data from the Korea National Health and Nutrition Examination Survey (1998-2012)

BACKGROUND/OBJECTIVES: The purpose of this study is to analyze daily kimchi, vegetable and fruit consumption by general characteristics and vegetable and fruit consumption from 1998 to 2012 by the Korean population based on the data of the KNHANES (Korea National Health and Nutrition Examination Survey). SUBJECTS/METHODS: This study is based on the 1998-2012 KNHNES. Analysis data on 54,700 subjects aged 19 years and older were obtained from health behavior interviews and the 24-hour dietary recall method. RESULTS: Daily kimchi consumption and portion size of kimchi decreased significantly from 1998 to 2012 (adjusted P for trend < 0.0001). Meanwhile, daily consumption of both non-salted vegetable and fruit with and without kimchi did not significantly change between 1998 and 2012. Reduced consumption of kimchi, non-salted vegetable, and fruit was observed for both genders as well as daily meal episodes and cooking locations. Male and female subjects with insufficient non-salted vegetable and fruit intake were increased 1.4 times and 1.3 times, respectively, in 2012 than 1998. All subjects consumed at least 400 g/day of non-salted vegetable, fruit, and kimchi in each survey year, although they consumed insufficient amounts (< 400 g/day) of non-salted vegetable and fruit without kimchi. CONCLUSIONS: Since Koreans generally consume high amounts of fermented vegetables, including kimchi, total vegetables and fruit. Consumption of these foods by the Korean adult population reached 400 g, which is the recommended intake of the WCRF/AICR. Based on this result, it is necessary to promote consumption of kimchi in the Korean population and research the development of low sodium kimchi in the future.

Porções de alimentos e número de refeições realizadas por adultos e idosos do muncípio de São Paulo: relação com excesso de peso e perfil lipídico / Food portion sizes and eating frequency of adults and elderly of São Paulo relationship with overweight and lipid profile

As contribuições do tamanho das porções dos alimentos e do número de refeições realizadas por dia para o aumento da prevalência do excesso de peso e para alterações no perfil lipídico em populações consumindo dieta ad libitum ainda não são bem estabelecidas, visto que a literatura apresenta resultados contraditórios. Objetivo: Avaliar a associação entre porções dos alimentos e o número de refeições realizadas com o excesso de peso e o perfil lipídico de adultos e idosos residentes do município de São Paulo. Métodos: Foram utilizados dados do estudo transversal de base populacional ISA - Capital 2008, referentes à amostra probabilística de residentes do município de São Paulo com 20 anos ou mais, de ambos os sexos. As informações, como dados socioeconômicos, antropométricos, de estilo de vida e inquérito alimentar, foram coletadas entre 2008 e 2010 por meio de visitas domiciliares e inquérito telefônico. No primeiro manuscrito da presente dissertação, os 1042 indivíduos foram classificados segundo o Índice de Massa Corporal (IMC) em duas categorias: com e sem excesso de peso. Dados de consumo alimentar foram obtidos por dois recordatórios alimentares de 24 horas (R24h). Os alimentos citados foram classificados em grupos e avaliados.

Dietary Intervention Strategies to Reduce Energy Intake in Diabetes / 임상당뇨병

Weight loss is physiologically beneficial in treating type 2 diabetes. Losing weight occurs when the body has a negative energy balance. However, many people have trouble in restricting their caloric intake. Strategies such as changing portion sizes, energy density and meal frequency can be useful for weight loss. Further research is needed on controlling food intake in the obese/overweight because of the complexity of eating behaviors.

Análise crítica da rotulagem e medidas caseiras de margarinas, cremes vegetais, manteigas, requeijões e azeites de dendê / Critical analysis of labeling and household measures of margarine, vegetable cream, butter, cream cheese, and palm oil

The aim of this study was to determine whether nutrition labeling of foods containing lipid is consistent with the Brazilian Legislation, as well as whether the portions described on the label match the volumetric capacity of tablespoons. We analyzed the labels of 23 packages of mar¬garine, 11 packages of vegetable cream, 45 packages of butter, 41 jars of cream cheese, and 12 bottles of palm oil, identified through online search and/or commercially available. A sample of each food group was weighed in 30 different types of level tablespoons. We verified that 20.6; 79.4 and 17.4% of the margarine and vegetables cream analyzed were designated as ?hydrogenated?, ?interesterified?, and ?trans-fat?, respectively; 11.8% were designated as ?butter + margarine?, which is not in accordance with the legislation. There was heterogeneity in the levels of sodium declared, with mean values ranging from 50.0-94.2 mg/10 g for margarine and vegetable cream, 1.0-115.0 mg/10 g for butter, and 106.3-174.3 mg/30 g for cream cheese. The average cholesterol content declared in butter ranged from 35.0 to 196.0 mg/10g. The labeling of palm oil showed no list of ingredients in 50% of the products assessed and incorrect statement of saturated fat content was present in 41.6% of the samples. The difference between the tablespoons ranged from 232.0 to 255.0%. It is worth noting that only 6.7; 6.7; 5.0 and 4.4 % presented the volumetric capacity of the tablespoons for margarine and vegetable cream, butter, cream cheese, and palm oil, respectively, in accordance with the legislation. The results demonstrate the need for standardization of tablespoons, updating, overt and efficient monitoring regarding the labeling of lipid foods in Brazil.

El objetivo de este estudio fue determinar si el etiquetado nutricional de los alimentos fuente de lípidos está de acuerdo con la ley brasileña vigente, así como si las porciones descritas en la etiqueta coinciden con la capacidad volumétrica de cucharadas soperas. Se analizaron las etiquetas de 23 margarinas, 11 cremas vegetales, 45 mantequillas, 41 requesones y 12 aceites de palma, productos que fueron identificados a través de una búsqueda por internet y/o adquiridos en el comercio. Se pesó una muestra de cada alimento, usando 30 diferentes tipos de cucharas soperas. Se verificó que el 20,6; 79,4 y 17,4% de las margarinas y cremas vegetales se etiquetaron como ?hidrogenadas?, ?interesterificadas? y ?con grasa trans?, respectivamente; también se verificó que el 11,8% se etiquetó como ?mantequilla + margarina?, ítem no previsto en la legislación. Se observó heterogeneidad en los niveles de sodio declarados, con los siguientes valores medios: 50,0-94,2 mg/10 g en las margarinas y cremas vegetales; 1,0-115 mg/10 g en las mantequillas y 106,3- 174,3 mg/30 g en los requesones. El contenido medio de colesterol declarado en las mantequillas osciló entre 35,0-196,0 mg/10g. El etiquetado del aceite de palma carecía del listado de ingredientes en el 50 % de los productos, y el nivel de grasa saturada estaba etiquetado de forma inexacta en el 41,6% de las muestras. La diferencia entre cucharadas soperas varió desde 232,0- 255,0%, puesto que el 6,7; 6,7; 5,0 y 4,4 % de las margarinas y cremas vegetales, mantequillas, requesones y aceites de palma, respectivamente, presentaron la capacidad volumétrica establecida en la legislación. Los resultados demuestran la necesidad de estandarización de las cucharadas soperas, actualización, fiscalización rigurosa y eficiente en el etiquetado de los alimentos lipídicos en Brasil.

O objetivo do presente estudo foi verificar se a rotulagem nutricional de alimentos fontes de lipídios está de acordo com a legislação brasileira vigente, bem como se as porções descritas no rótulo coincidem com a capacidade volumétrica de colheres de sopa. Foram analisados os rótulos de 23 margarinas, 11 cremes vegetais, 45 manteigas, 41 requeijões e 12 azeites de dendê, identificados por meio de busca on-line e/ou adquiri¬dos no comércio. Pesou-se uma amostra de cada alimento em 30 diferentes tipos de colheres de sopa niveladas. Verificou-se que 20,6%; 79,4% e 17,4% das margarinas e cremes vegetais foram designadas como ?hidrogenadas?, ?interesterificadas? e ?com gordura trans?, respectivamente; 11,8 % foram denominadas ?manteiga + mar¬garina?, item não previsto na legislação. Verificou-se heterogeneidade nos teores de sódio declarados. Os valores médios encontrados foram: 50,0-94,2 mg/10 g nas margarinas e cremes vegetais; 1,0-115,0 mg/10 g nas manteigas e 106,3-174,3 mg/30 g, nos requeijões. O teor médio de colesterol declarado nas manteigas variou entre 35,0-196,0 mg/10g. A rotulagem do azeite de dendê demonstrou ausência da listagem de ingredientes em 50% dos produtos e a declaração incorreta do teor de gordura saturada esteve presente em 41,6% dessas amostras. A diferença entre as colheres variou entre 232,0% e 255,0%, sendo que 6,7%; 6,7%; 5,0% e 4,4% destas apre¬sentaram capacidade volumétrica para marga¬rinas e cremes vegetais, manteigas, requeijões e azeites de dendê, respectivamente, em conformidade com a legislação. Os resultados demonstram a necessidade de uma padronização das colheres de sopa, atualização, fiscalização ostensiva e eficiente quanto à rotulagem de alimentos lipídicos no Brasil.

Porções de alimentos e número de refeições realizadas por adultos e idosos do município de São Paulo: relação com excesso de peso e perfil lipídico / Food portion sizes and eating frequency of adults and elderly of São Paulo relationship with overweight and lipid profile

As contribuições do tamanho das porções dos alimentos e do número de refeições realizadas por dia para o aumento da prevalência do excesso de peso e para alterações no perfil lipídico em populações consumindo dieta ad libitum ainda não são bem estabelecidas, visto que a literatura apresenta resultados contraditórios. Objetivo: Avaliar a associação entre porções dos alimentos e o número de refeições realizadas com o excesso de peso e o perfil lipídico de adultos e idosos residentes do município de São Paulo. Métodos: Foram utilizados dados do estudo transversal de base populacional ISA - Capital 2008, referentes à amostra probabilística de residentes do município de São Paulo com 20 anos ou mais, de ambos os sexos. As informações, como dados socioeconômicos, antropométricos, de estilo de vida e inquérito alimentar, foram coletadas entre 2008 e 2010 por meio de visitas domiciliares e inquérito telefônico. No primeiro manuscrito da presente dissertação, os 1042 indivíduos foram classificados segundo o Índice de Massa Corporal (IMC) em duas categorias: com e sem excesso de peso. Dados de consumo alimentar foram obtidos por dois recordatórios alimentares de 24 horas (R24h). Os alimentos citados foram classificados em grupos e avaliados. Foi calculada a mediana da porção, percentual de relato e contribuição energética para homens e mulheres com e sem excesso de peso. Modelos de regressão logística foram utilizados para avaliar a associação entre o tamanho das porções...

The contribution of food portion sizes and eating frequency to the rising prevalence of overweight and to lipid profile changes in populations consuming ad libitum diet is not well established, as contradictory results are presented in literature. Objective: Verify the association between food portion sizes, eating frequency, being overweight and lipid profile in a representative population sample of adults and elderly in São Paulo. Methods: The study considered data from cross-sectional population-based ISA-Capital 2008 with random sample of residents of São Paulo aged above 20 years and both sexes. Socioeconomic, anthropometric, lifestyle and diet information was collected between 2008 and 2010 in personal or phone interviews. In the first article of this dissertation, 1042 individuals were classified according to Body Mass Index (BMI) into two categories: with and without excess body weight. Food consumption data were obtained by two 24-hour food recall (R24h). The reported foods were classified into groups and evaluated. The median portion, reported percentage and energy contribution for men and women with and without EBW were calculated. Logistic Regression models were used to evaluate the association of food portion sizes with being overweight. In the second article, data from 521 adults and elderly who had information about lipid profile, the second R24h and did not use hipocolesterolemics were used. Individuals were classified according to eating...

Energy Content Estimation by Collegians for Portion Standardized Foods Frequently Consumed in Korea

The purpose of this study is to estimate Korean collegians' knowledge of energy content in the standard portion size of foods frequently consumed in Korea and to investigate the differences in knowledge between gender groups. A total of 600 collegians participated in this study. Participants' knowledge was assessed based on their estimation on the energy content of 30 selected food items with their actual-size photo images. Standard portion size of food was based on 2010 Korean Dietary Reference Intakes, and the percentage of participants who accurately estimated (that is, within 20% of the true value) the energy content of the standard portion size was calculated for each food item. The food for which the most participants provided the accurate estimation was ramyun (instant noodles) (67.7%), followed by cooked rice (57.8%). The proportion of students who overestimated the energy content was highest for vegetables (68.8%) and beverages (68.1%). The proportion of students who underestimated the energy content was highest for grains and starches (42.0%) and fruits (37.1%). Female students were more likely to check energy content of foods that they consumed than male students. From these results, it was concluded that the knowledge on food energy content was poor among collegians, with some gender difference. Therefore, in the future, nutrition education programs should give greater attention to improving knowledge on calorie content and to helping them apply this knowledge in order to develop effective dietary plans.

Recommendation of Serving Size of the Meal Service of Community Child Centers in Korea / 대한지역사회영양학회지

OBJECTIVES: This study was performed to set easily applicable portion sizes by sex and age for children at the Community Child Centers (CCC) in Korea. METHODS: Considering the age and gender specific energy level at Target Patterns for children aged 6-18 years, which were suggested as a part of the 2010 Korean Food Guidance System (KFGS), we set three meal sizes. We reclassified the recommended daily servings of Grains, Meat.fish.eggs.beans and Vegetables group at Target Patterns into three meal sizes, and then calculated the recommended serving per meal. Each proposed amount of food per meal was calculated based on serving size of foods commonly eaten at KFGS, which was then allocated to five meal components; rice, soup, stew, protein and vegetable side-dishes and Kimchi. Each proposed amount of food per meal was applied to 173 menus' recipes from CANpro 3.0 as main ingredient's amounts. We cooked the 173 menus at the medium size and measured their weights after cooking. RESULTS: Each recommended serving per meal was 0.75, 0.9 and 1.2 for Grains; 1.2, 1.6 and 2.4 for Meat.fish.eggs.beans; 2, 2.4 and 2.8 for Vegetables by meal sizes. Among five meal components, the ratio of small and large to medium size was 1/5 less and 1/3 more for rice and 1/3 less and 1/3 more for soup.stew, protein side-dish and Kimchi, respectively. We suggested the same amount for a vegetable side-dish to encourage vegetable intake. Proper portion sizes per meal of medium were rice 190 g, soup.stew 210 g (solid ingredients 60 g), protein side-dish 100 g (meat.eggs.beans) and 70 g (fish), vegetable side-dish 80g and Kimchi 30 g. CONCLUSIONS: Proper portion size per meal suggested in this study may be useful at the CCC where dietitians are not available and the approach could be applicable to the other types of meal services.
