Resumo: RESUMEN Propósito: La inexistencia de datos a nivel nacional y regional sobre el valor nutricional (VN) de la alimentación ofrecida en comedores comunitarios dirigidos por Organizaciones No Gubernamentales (ONG), que atienden población infantil de zonas urbano marginales, junto con el incremento en la prevalencia de exceso de peso reportada por el Ministerio de Educación Pública de Costa Rica (MEP) en el 2016, justifican el estudio del VN del almuerzo servido a niños(as), que participan en programas de alimentación complementaria en zonas urbano marginales de San José, Costa Rica. Método: Se analizaron mediante muestreo aleatorio 321 platos de almuerzo, durante 12 días en dos comedores. Se reconstruyeron recetas y se determinaron tamaños de porción mediante pesaje directo y se calculó el VN promedio por plato. Resultados: El valor energético fue cercano a la recomendación nutricional. Sin embargo, valores de proteína, grasa total, grasa insaturada, fibra dietética, calcio y potasio fueron inferiores a las recomendaciones y por el contrario, carbohidratos totales, azúcar agregada, grasa saturada y sodio fueron superiores a la recomendación nacional. Conclusión: No es suficiente ofrecer un aporte adecuado de energía. Los excesos y deficiencias de nutrientes reflejan un patrón alimentario obesogénico que suma vulnerabilidad a la condición de pobreza y pobreza extrema de la población infantil de zonas urbano-marginales.

ABSTRACT Purpose: The lack of data at a national and regional level regarding the nutritional value (NV) of the food offered in community feeding programs run by Non-Governmental Organizations, which serve the population of marginal urban areas (an important indicator of infant health), along with the increase in the prevalence of excess weight reported in 2016 by the Ministry of Public Education of Costa Rica, justifies the study of the NV of the lunch served to preschool and school-aged children, who participate in complementary feeding programs in marginal urban areas of San José, Costa Rica. Method: 321 meals served were analyzed over 12 days, in 2 food services. Recipes were reconstructed, and portion sizes were determined by direct weighing of food served and the average NV per dish was calculated. Results: The energy value of the lunch served was similar to the nutritional recommendation. However, for the values of protein, total fat, unsaturated fat, dietary fiber, calcium and potassium which were lower than the nutritional recommendation and on the contrary, the content of total carbohydrates, added sugar, saturated fat and sodium was excessive. Conclusion: It is not enough to offer minors an adequate energy amount. Nutrient excesses and deficiencies reflect an obesogenic food pattern, which adds vulnerability to the condition of poverty and extreme poverty of the child population of marginalized urban areas.

Resumo: BACKGROUND: Cellulose as a potential feed resource hinders its utilization because of its complex structure, and cellulase is the key to its biological effective utilization. Animal endogenous probiotics are more susceptible to colonization in the intestinal tract, and their digestive enzymes are more conducive to the digestion and absorption of feed in young animals. Min pigs are potential sources of cellulase probiotics because of the high proportion of dietary fiber in their feed. In this study, the cellulolytic bacteria in the feces of Min pigs were isolated and screened. The characteristics of enzymes and cellulase production were studied, which provided a theoretical basis for the rational utilization of cellulase and high-fiber food in animal production. RESULTS: In our study, 10 strains of cellulase producing strains were isolated from Min pig manure, among which the M2 strain had the best enzyme producing ability and was identified as Bacillus velezensis. The optimum production conditions of cellulase from strain M2 were: 2% inoculum, the temperature of 35°C, the pH of 5.0, and the liquid loading volume of 50 mL. The optimum temperature, pH and time for the reaction of cellulase produced by strain M2 were 55°C, 4.5 and 5 min, respectively. CONCLUSIONS: Min pigs can be used as a source of cellulase producing strains. The M2 strain isolated from feces was identified as Bacillus velezensis. The cellulase from M2 strain had a good activity and the potential to be used as feed additive for piglets.

Título: Influência da nutrição na expressão de genes relacionados à obesidade / Influence of nutrition on the expression of genes related to obesity
Fonte: Arq. ciências saúde UNIPAR;24(2):81-85, maio-ago. 2020.
Idioma: pt.
Resumo: A obesidade possui vários prejuízos para a saúde e está associada à inúmeras patologias e baixa expectativa de vida. O desequilíbrio alimentar é um fator que necessita de atenção especial, pois é capaz de alterar as interações entre nutrientes e genes. O objetivo deste trabalho foi verificar as principais linhas de pesquisa associadas à nutrigenômica, e evidenciar a relação da influência da nutrição na expressão de genes relacionados à obesidade. Realizou-se o levantamento bibliográfico e a análise cienciométrica por meio do banco de dados publicados na Biblioteca Virtual em Saúde (BVS) e do Centro Latino-Americano de Informação em Ciências da Saúde (BIREME). Identificou-se 118 artigos originais, os quais foram agrupados em cinco classes: restrição calórica, expressão gênica, alimentos, intervenção dietética e diversos. Os resultados evidenciaram que a restrição calórica possui relação direta da expressão gênica com o controle das células cancerígenas e a diminuição do excesso de tecido adiposo. Além disso, a análise cienciométrica relacionou a importância das fibras alimentares na redução do colesterol e sensibilidade à insulina, bem como a ação do jejum na regulação negativa de genes que contribuem para o crescimento do tecido adiposo. Dessa forma, este artigo fornece princípios ideológicos para auxiliar especialistas na aplicabilidade de estratégias para atingir a redução de peso sustentável por meio da expressão gênica.

Obesity has several health risks and is associated with numerous pathologies and low life expectancy. Food imbalance is a factor that needs special attention, as it is able to change the interactions between nutrients and genes. This study aimed at verifying the main lines of research associated with nutrigenomics, and at showing the relationship of the influence of nutrition on the expression of genes related to obesity. The bibliographic survey and scientometric analysis were carried out through the database published in the Biblioteca Virtual em Saúde (BVS) and the Centro Latino-Americano de Informação em Ciências da Saúde (BIREME). A total of 118 articles of original research were identified, and were grouped into five categories: caloric restriction; gene expression; food; dietary intervention; and miscellaneous. The results showed that caloric restriction has a direct relationship between gene expression and the control of cancer cells and the reduction of excess adipose tissue. Furthermore, the scientometric analysis related the importance of dietary fibers in reducing cholesterol and insulin sensitivity as well as the action of fasting in the negative regulation of genes that contribute to the growth of adipose tissue. Thus, this paper provides ideological principles to assist specialists in the applicability of strategies to achieve sustainable weight reduction through gene expression.

Resumo: El amaranto, quinua y tarwi, son alimentos (cereales) de gran valor nutritivo y medicinal, consecuentemente es importante estudiar estas propiedades para el beneficio en la calidad de la alimentación (por su contenido en macronutrientes) como para la prevención de enfermedades. El desayuno como primera comida que se consume en el día cumple una función esencial, debido a que cubre las primeras necesidades nutricionales requeridas por el organismo, para la obtención de fuentes de energía, materias primas en la biosíntesis de compuestos necesarios para el sistema inmune, y otros. En este trabajo se realizó una evaluación de las propiedades nutritivas de estos productos cuando se complementan al desayuno, principalmente a través de la valoración de la ingesta calórica y los macronutrientes, medición de parámetros antropométricos y otros. Después del consumo del amaranto, quinua y/o tarwi en el desayuno en un grupo de voluntarias (estudiantes) durante 4 semanas, se observó una disminución significativa de los parámetros antropométricos relacionados con el Peso, Circunferencia de la Cintura (CCi) e Índice de masa corporal (IMC). Este estudio también reveló que, el consumo calórico (kcal/día) en el desayuno de este grupo, fue bajo y moderado con un promedio de 279,7 ± 70,9 kcal/día, equivalente al 14 % del GET (Gasto energético total). También se evidenció una pobre ingesta de hidratos de carbono, proteínas, grasas y una deficiente ingesta de fibra dietética (44,8± 14,1; 9,8 ± 3,5; 7,3 ± 2,2 y 0,04 ± 0,08 g/díarespectivamente). Efectos significativos fueron observado en el aumento del aporte calórico (57,9; 58,1 (p<0,05); 59,6 (p<0,01); Kcal/día con el amaranto, quinua y tarwi, respectivamente, así como en los macronutrientes.

Amaranth, Quinoa and Tarwi, are foods with extraordinary nutritional and medicinal properties. The study of these properties is important to improve the feed quality and prevent diseases in the population. Breakfast as the first meal consumed in the day fulfills an essential function, because it covers the first nutritional needs required by the body, for obtaining sources of energy, raw materials in the biosynthesis of compounds necessary for the immune system, and others. In this work an evaluation of the nutritional properties of these products was carried out when they complement the breakfast, mainly through the evaluation of the caloric intake and the macronutrients, anthropometric parameters measurement and others. After consumption of amaranth, quinoa and / or tarwi at breakfast in a group of volunteers (students) for 4 weeks, a significant decrease in the anthropometric parameters related to Weight, Waist Circumference (CCi) and Index of Body mass (BMI). This study also revealed that the caloric intake (kcal / day) in this group's breakfast was low and moderate with an average of 279.7 ± 70.9 kcal / day, equivalent to 14% of GET (Total Energy Expenditure). Indeed, poor dietary intake of carbohydrates, proteins, fats and fiber (44.8 ± 14.1, 9.8 ± 3.5, 7.3 ± 2.2 and 0.04 ± 0.08 g / day respectively) was evidenced. The results showed significant effects on the increase in caloric intake (57.9, 58.1 = p <0.05, 59.6 = p <0.01), Kcal/day with amaranth, quinoa and tarwi respectively, As well as in macronutrients.

Fonte: Arq. ciências saúde UNIPAR;21(3):193-199, set-dez. 2017. tab, ilus.
Idioma: pt.
Resumo: O bagaço de mandioca, resíduo da extração de amido, apresenta alto teor de fibras e pode ser utilizado em diversas aplicações, dentre elas biscoitos. Neste trabalho objetivou-se utilizar bagaço de mandioca na produção de cookies. O bagaço foi obtido junto à empresa Cia Lorenz, da cidade de Umuarama-PR, com umidade de 84,21% e 11,20% de amido. As quatro formulações de cookie foram preparadas (F1; F2; F3; F4) empregando variações na proporção farinha de trigo/ bagaço de mandioca (50/00; 27,8/40; 17,8/50; 7,8/60). Os ingredientes foram misturados em batedeira, divididos em porções, laminados na espessura média de 5 mm e cortados em matriz de 30 mm de diâmetro. Os biscoitos foram analisados antes do forneamento (AF) e após o forneamento (DF) quanto: a) ao volume de expansão e b) umidade. Os biscoitos tipo cookies foram avaliados por 100 participantes em relação a aceitação sensorial por atributos e intenção de compra. Avaliou-se o teor de fibra bruta do bagaço de mandioca e dos biscoitos formulados. A umidade (AF/DF) dos biscoitos foi de F1: 28,05%/3,33%; F2: 40,24%/3,77%; F3: 45,19%/4,98% e F4:54,12%/6,17%. O volume de expansão determinado foi de F1: 4,05cm3; F2: 0,77cm3; F3: -0,39cm3; F4: -1,13cm3. O teor de fibras brutas do bagaço foi de quase 17% e dos biscoitos foi de F1: 1,14%; F2: 5,51%; F3: 7,98% e F4: 10,22%, demonstrando quantidade considerável de fibras nos biscoitos acrescidos do bagaço. As amostras F3 e F4 obtiveram altos escores na aceitação global (7,1 e 7,25, respectivamente) e textura (6,07 e 6,13, respectivamente). O maior nível de adição do bagaço de mandioca não proporcionou alteração na cor, aroma e sabor avaliados sensorialmente em relação a amostra isenta de bagaço. Com relação à intenção de compra, as amostras F1, F3 e F4 obtiveram as maiores médias, mostrando que há um potencial mercado para o produto proposto.

Cassava bagasse, the residue of starch extraction, has high fiber content and can be used in various applications, including biscuits. This study aimed at using cassava bagasse in the production of cookies. Bagasse was obtained from Cia Lorenz (Umuarama-PR), with moisture of 84.21±0.04% and 11.20±0.05% starch. Four cookie formulations were prepared (F1; F2; F3; F4) employing variations in the proportion of wheat flour/cassava bagasse (50/00, 27.8/40, 17.8/50, 7.8/60). The ingredients were mixed in the mixer, and divided into portions, laminated at an average thickness of 5 mm and cut in a 30-mm diameter matrix. The biscuits were analyzed before and after baking in relation to volume expansion and moisture. Cookies were evaluated by 100 participants in relation to sensory acceptance by attributes and purchase intention. Crude fiber content of the cassava bagasse and the formulated biscuits were evaluated. Moisture content (FA/DF) of the cookies was F1: 28.05%/3.33%; F2: 40.24%/3.77%; F3: 45.19%/4.98% and F4: 54.12%/6.17%. The expansion volume was F1: 4.05cm3; F2: 0.77cm3; F3: -0.39cm3; F4: -1.13cm3. Crude fiber content of the bagasse was almost 17% and of the biscuits was F1: 1.14%; F2: 5.51%; F3: 7.98% and F4: 10.22%, demonstrating a considerable amount of fiber in the biscuits added to the bagasse. Samples F3 and F4 obtained high scores in global acceptance (7.1 and 7.25, respectively) and texture (6.07 and 6.13, respectively). The higher level of cassava bagasse did not change the color, aroma and taste evaluated in relation to the bagasse-free sample. Regarding the purchase intention, samples F1, F3 and F4 obtained the highest averages, showing that there is a potential market for the proposed product.

Título: Efeitos do incremento da fibra em detergente neutro na ração de suínos sobre a histologia de segmentos do trato intestinal / Effects of increasing neutral detergent fiber in swine feed on the histology of segments of the intestinal tract
Fonte: Braz. j. vet. res. anim. sci;43(2):210-219, 2006. ilus, tab.
Idioma: pt.
Resumo: Objetivou-se registrar os efeitos da inclusão de 0 ou 8% de fibra em detergente neutro na ração de suínos, sobre a histologia intestinal de suínos nas fases de creche e de crescimento-terminação. Foram utilizados suínos mestiços alimentados à vontade com rações isoprotéicas e isoenergéticas, em experimento inteiraménte casualizado. Ao final de cada período, os animais foram abatidos, eviscerados e os cortes histológicos realizados. A ração fibrosa promoveu, na creche, significativo aumento da proporção volumétrica glandular na mucosa cecal; redução da proporção volumétrica ocupada pelas células caliciformes no epitélio do jejuno; aumento das áreas de células caliciformes produtoras de muco, presentes no epitélio glandular do jejuno, ceco e colo; além de aumento na intensidade do muco presente nas células caliciformes do duodeno e colo. Ao final da fase de terminação, os suínos alimentados com as dietas fibrosas, apresentaram aumento da proporção volumétrica glandular do epitélio do ceco, mas ligeira redução da área das células caliciformes produtoras de muco, no epitélio do colo. Estes dados sugerem uma adaptação, possivelmente um mecanismo de proteção, do epitélio à ação abrasiva exercida pelo oferecimento contínuo de fibra dietética na dieta de suínos, particularmente na fase creche.

The aim of this work was to evaluate the effects of including 0% or 8% of neutral detergent fiber in swine rations on the histological aspects of gastrointestinal segments of starting and growing-finishing pigs. It was employed cross-bred animals fed isoproteic and isoenergetic ad libitum rations in a completely random.ed experimental design. At the end of each experiment, animals were slaughtered, eviscerated and pieces from digestive organs prepared for histological studies. For starter animals, the fibrous diet increased significantly the cecal glandular volumetric proportion; reduced the goblet cell volumetric proportion on jejunum epithelium; and enhanced the intensity of mucous production by duodenal and colonic mucous cells. By the end of finishing period, the pigs fed fibrous diets showed increased glandular surface area on cecal epithelium but slight reduction of mucosal cell surface area on the colon. These data suggest an epithelium adaptation, possibly a protective mechanism against the abrasive action promoted by the continuous feeding of dietary fiber to swine, particularly in the starting period.

Título: Wine grape pomace flour improves blood pressure, fasting glucose and protein damage in humans: a randomized controlled trial
Fonte: Biol. Res;48:1-10, 2015. tab.
Idioma: en.
Projeto: FONDEF.
Resumo: BACKGROUND: The Mediterranean diet is a healthy diet with positive scientific evidence of preventing chronic diseases. Bioactive components support the healthy properties of the Mediterranean diet. Antioxidants and fiber, two components of the Mediterranean diet, are key functional nutrients for healthy eating and nutrition. Wine grape pomace is a rich source of these dietary constituents and may be beneficial for human health. Our hypothesis was that the intake of red wine grape pomace flour (WGPF) prepared from red wine grapes (Cabernet Sauvignon variety) reduced the metabolic syndrome in humans. To evaluate the effect of WGPF on components of metabolic syndrome we design a 16-week longitudinal intervention study. Thirty-eight males, 30-65 years of age, with at least one component of metabolic syndrome, were randomly assigned to either the intervention group (n = 25) or the control group (n = 13). At lunch, the intervention group was given 20 g of WGPF per day, which contained 10 g of dietary fiber, 822 mg of polyphenols and an antioxidant capacity of 7258 ORAC units. Both groups were asked to maintain their regular eating habits and lifestyles. Clinical evaluation, anthropometric measurements and biochemical blood analyses were done at the beginning and the end of the study. RESULTS: WGPF intake significantly decreased systolic and diastolic blood pressure as well as fasting glucose levels. Plasma γ-tocopherol and δ-tocopherol increased and carbonyl group in plasma protein decreased in WGPT group, significantly. No significant effect was observed for waist circumference, HDL cholesterol, triglycerides, total antioxidant capacity and vitamin C in and between groups. The group-dependent magnitude of the differences between the baseline and final postprandial insulin values and γ-tocopherol concentrations was statistically significant. CONCLUSIONS: The consumption of WGPF-rich in fiber and polyphenol antioxidants, as a food supplement in a regular diet improves blood pressure, glycaemia and postprandial insulin. In addition, increased antioxidant defenses and decreased oxidative protein damage indicating attenuation of oxidative stress. WGPF might be a useful food ingredient for health promotion and chronic disease prevention.

Título: The Effects of Fermentable Dietary Fiber on Performance and Metabolism of Nile Tilapia (Oreochromis niloticus)
Fonte: Braz. arch. biol. technol;63:e20190396, 2020. tab.
Idioma: en.
Resumo: Abstract This study was conducted to evaluate the inclusion of new prebiotics in the diet on performance and metabolism (liver protein, glucose and glycogen) of Nile tilapia. For 60 days, 720 Nile tilapia (3.4 ± 0.60 g) were maintained in 24 polypropylene tanks (280 liters). Fish were fed with experimental diets with addition of 2.5 and 5 g kg-1 of dietary fiber of citrus pulp (DFCP), dietary fiber of linseed (DFL) and Actigen®. The experimental design was completely randomized with a 3x2 factorial arrangement. At the end of the period, there was higher final weight of tilapias fed on diets containing DFCP and DFL, and regardless of prebiotic, the best results in the final weight and length were observed for inclusion of 2.5 g kg-1. There was higher body protein deposition in tilapia fed on diets containing DFCP, without differences from those with inclusion of DFL. Total fat deposition was higher for the lowest level of inclusion (2.5 g kg-1). The digestive somatic index was higher for the diet with inclusion of DFCP, which did not differ from the diet with inclusion of Actigen®. There were higher concentrations of liver glycogen in the diets containing DFCP and Actigen®. Faced with the search for alternative growth promoters, this study confirms the possibility of using the new prebiotics (DFCP and DFL) in nutrition of Nile tilapia, because they showed efficiency equivalent to the prebiotic Actigen®.

Título: Propiedades bioactivas de frutas tropicales exóticas y sus beneficios a la salud / Bioactive properties of exotic tropical fruits and their health benefits
Fonte: Arch. latinoam. nutr;70(3):205-214, sept. 2020. tab, ilus.
Idioma: es.
Resumo: Las frutas exóticas se encuentran dentro del grupo de las frutas tropicales y su carácter perecedero limita su exportación a mercados distantes. En general, su consumo es local, son subutilizadas o poco valoradas tanto en el hogar como industrialmente; sin embargo, debido su alto valor nutricional, su consumo se ha incrementado significativamente en los últimos años. Estas frutas son fuente de compuestos bioactivos como fibra, vitamina C, carotenoides, ácidos fenólicos y polifenoles, los cuales han sido asociados a la reducción de los riesgos de enfermedades crónicas causadas por el estrés oxidativo. Estos compuestos bioactivos han demostrado que poseen varias actividades biológicas in vitro e in vivo incluyendo actividad antioxidante, antimicrobiana, antiinflamatoria, antiedad, neuroprotectora y antiviral entre otras. Por lo tanto, la obtención de ingredientes funcionales a partir de las frutas tropicales consideradas exóticas resulta viable; así como su utilización para el desarrollo de alimentos funcionales y nutracéuticos, para elaboración de productos de la industria farmacéutica y la conservación de alimentos. En la presente revisión se discute la información más relevante publicada en el período 2010-2020 de las principales bases de datos científicas, incluyendo Scopus, Science Direct, PubMed, Medline y Scielo, sobre los compuestos fenólicos y las bioactividades reportadas de las frutas tropicales exóticas como acai (Euterpe oleraceae), acerola (Malpighia emarginata), buruti (Mauritia flexuosa) caqui (Diospyros kaki), chicozapote (Manilkara zapota), litchi (Litchi chinensis), maracuyá (Passiflora edulis), noni (Morinda citrifolia) rambután (Nephelium lappaceum), pitaya blanca (Hylocereus undatus), pitaya roja (Hylocereus polyrhizus) y su relación con sus potenciales efectos benéficos en la salud(AU)

Exotic fruits are found in the group of tropical fruits and their perishable nature limits their export to distant markets. In general, their consumption is local; they are underutilized or little valued both at home and industrially; however, its consumption has increased significantly in recent years due to its high nutritional value. These fruits are a source of bioactive compounds such as fiber, vitamin C, carotenoids, phenolic acids and polyphenols, which have been associated with reducing the risks of chronic diseases caused by oxidative stress. These bioactive compounds have been shown to possess various in vitro and in vivo biological activities, including antioxidant, antimicrobial, antiviral, anti-inflammatory, anti-aging, neuroprotective, and among others. Therefore, obtaining functional ingredients from tropical fruits considered exotic is viable and used to develop functional and nutraceutical foods, prepare products for the pharmaceutical industry and food preservation. This review discusses the most relevant information published in the 2010-2020 period from the main scientific databases, including Scopus, Science Direct, PubMed, Medline and Scielo, on phenolic compounds and reported bioactivities of exotic tropical fruits such as acai (Euterpe oleraceae), acerola (Malpighia emarginata), persimmon (Diospyros kaki), chicozapote (Manilkara zapota), litchi (Litchi chinensis), passion fruit (Passiflora edulis) noni (Morinda citrifolia), rambutan (Nephelium lappaceum), white pitaya (Hylocereus undatus) and red pitaya (Hylocereus polyrhizus) and their relationship with their potential beneficial effects on health(AU)

Resumo: Objetivo: analisar a frequência de consumo de fibras alimentares em universitários de Várzea Grande - MT. Métodos: estudo transversal com estudantes de um Centro Universitário de Várzea Grande - MT, em 2017. Foi aplicado um questionário sobre o consumo de alimentos ricos em fibras com 5 opções de respostas e cada uma dessas opções recebia uma pontuação que incluíam: menos de uma vez por semana (zero ponto); cerca de uma vez por semana (um ponto); duas a três vezes por semana (dois pontos); 4 a 6 vezes por semana (três pontos) e; diário (quatro pontos). As pontuações foram somadas e os indivíduos classificados em dieta pobre em fibras (pontuação menor ou igual a 19 pontos); consumo regular de fibras (20 a 29 pontos) e consumo adequado de fibras (maior ou igual a 30 pontos). Calculou-se o Índice de Massa Corporal e o risco para morbidades pela circunferência da cintura. Resultados: entre os avaliados, 77,2% eram do sexo feminino e 48,8% apresentaram um baixo consumo de fibras, 39,6% estavam com excesso de peso e 24,2% possuíam risco de morbidades. Os universitários apresentaram elevada frequência diária de consumo de frutas, verduras, legumes e leguminosas. Conclusão: quase metade dos entrevistados apresentou baixo consumo de fibras e frequência igual ou menor que uma vez por semana para os sucos naturais, cereais integrais e pão integral. Para a melhoria dos resultados, deve-se limitar o consumo de alimentos processados e ultraprocessados e dar preferência para alimentos naturais ou minimamente processados.

Objective: to analyze the frequency of dietary fiber consumption among college students in. Methods: a cross-sectional study was carried out with students from a University Center of Várzea Grande - MT, in 2017. A questionnaire on the consumption of fiber-rich foods with 5 response options was applied and each of these options received a score that included: less than once per week (zero point); about once a week (one point); 2 to 3 times a week (two points); 4 to 6 times a week (three points); Daily (four points). The scores were summed and the individuals classified into a diet low in fiber (score less than or equal to 19 points); regular fiber consumption (20 to 29 points) and adequate fiber consumption (greater than or equal to 30 points). The Body Mass Index and the risk for waist circumference morbidity were calculated. Results: among the evaluated, 77.2% were female and 48.8% had a low fiber intake, 39.6% were overweight and 24.2% had a risk of morbidities. The university students presented high daily frequency of consumption of fruits, vegetables, legumes and vegetables. Conclusion: almost half of those interviewed had low fiber intake and had less than or equal to once a week for natural juices, whole grains and whole grain bread. To improve the results, the consumption of processed and ultraprocessed foods should be limited and preference should be given to natural or minimally processed foods.
