RESUMO

Introducción. La calidad de los carbohidratos consumidos juega un papel importante en la prevención de las enfermedades crónicas no transmisibles (ECNT). Objetivo. Analizar el índice de calidad de los carbohidratos (ICC) en la población urbana costarricense y su relación con las variables sociodemográficas, antropométricas y la calidad y la diversidad de la dieta. Materiales y métodos. Los datos provienen del Estudio Latinoamericano de Nutrición y Salud, en una muestra representativa de 798 personas entre 15 y 65 años que residen en zonas urbanas de Costa Rica (2014- 2015). En una visita domiciliaria se administró un cuestionario para recolectar los datos sociodemográficos y se pesó y midió a los participantes. El consumo dietético se obtuvo mediante dos recordatorios de 24 horas en días no consecutivos. El ICC se calculó mediante el consumo de fibra, el índice glicémico, la relación carbohidratos sólidos/líquidos y la relación granos enteros/granos totales. Se comparó el ICC según el sexo, el grupo de edad, el nivel socioeconómico, el estado nutricional, la circunferencia de cintura y la calidad y diversidad de la dieta de los participantes. Resultados. El ICC se asoció positivamente con un mayor consumo de energía, carbohidratos totales, proteínas, grasas, colesterol, frutas, vegetales y leguminosas (p<0,001). Un mayor ICC se asoció positivamente con un mayor porcentaje de adecuación de micronutrientes y mayor índice de diversidad y calidad de la dieta (p<0,001), así como con un menor índice de masa corporal y una menor circunferencia de cintura al ajustar por sexo y edad (p<0,005). Conclusiones. El presente estudio demostró que un mayor ICC se asocia significativamente con mejores indicadores dietéticos e índice de masa corporal, por lo que resulta fundamental establecer en Costa Rica pautas dietéticas que permitan aumentar la calidad de los carbohidratos de la dieta con el fin de contribuir en la prevención de las ECNT(AU)

Introduction. The carbohydrate quality index (CQI) plays an important role in the prevention of chronic non-communicable diseases (NCD) and adequate macro and micronutrient intake. Objective. To analyze the carbohydrate quality index (CCI) in the Costa Rican urban population and its relationship with sociodemographic and anthropometric variables and the quality and diversity of the diet. Materials and methods. Data come from the Latin American Nutrition and Health Study (ELANS), in a representative sample of 798 people between 15 and 65 years of age who reside in urban areas of Costa Rica (2014-2015). During a home visit, a questionnaire was administered to collect sociodemographic data, and participants were measured and weighed. Dietary intake was obtained through two 24-hour recalls in non- consecutive days. The CQI was calculated using fiber intake, glycemic index, liquid/solid carbohydrate ratio, and whole grain/total grains. CCI was then compared according to sex, age-group, socioeconomic level, nutritional status and diet quality and diet diversity. Results. The CQI was positively associated with energy intake, total carbohydrates, proteins, fats, cholesterol, fruits, vegetables, and legumes (p<0,001). Also, CQI was associated with a higher percentage of micronutrient adequacy and diet quality and diversity (p<0,001), as well as with a lower body mass index and lower waist circumference when adjusting for sex and age (p<0,005). Conclusions. The present study showed that higher CQI is associated with better dietary and body mass index, which shows that it is essential to establish dietary guidelines for public health in Costa Rica that allows increasing the quality of carbohydrates in the diet to contribute to the prevention of chronic NCD(AU)

RESUMO

En el presente estudio se evalúa la incorporación de cáscaras de zanahoria como ingrediente en galletas en diferentes concentraciones, de esta manera se pueden disminuir los desperdicios además de aprovechar nutrientes, compuestos bioactivos y fibra dietética de las cáscaras. Se recolectaron cáscaras de zanahorias, se lavaron, deshidrataron a 60°C por 24 horas y posteriormente de molieron finamente para obtener harina de cáscara de zanahoria (HCZ). Se desarrollaron galletas con la incorporación de 0, 5, 10 y 20% de HCZ en reemplazo de harina (Muestras CZ0, CZ5, CZ10 y CZ20 respectivamente). Se evaluó la preferencia y aceptabilidad sensorial de las muestras de galletas, mediante prueba de ordenamiento y escala hedónica de 9 puntos por parámetros (apariencia, color, aroma, sabor, textura, aceptabilidad general) respectivamente. También se evaluó la saciedad producida por su consumo mediante "Cociente de Saciedad" (CS) que utiliza la Escala Visual Análoga (EVA) para cuantificar el estado de saciedad en diferentes tiempos. Se determinó el contenido de fibra dietética (FD) en la HCZ y en las muestras de galletas por método enzimático-gravimétrico. Los resultados demostraron que la muestra CZ20 logró la primera preferencia sensorial y la mayor aceptabilidad sensorial en forma significativa (p<0.05). La incorporación de HCZ en galletas produjo aumento del contenido de fibra dietética y del CS. En base a los resultados obtenidos se concluyó que la mejor opción resultó ser la galleta con 20% de HCZ, ya que sensorialmente es la de mayor preferencia y de mayor aceptabilidad, contiene más fibra dietética y provoca más saciedad.

In the present study, the incorporation of carrot peels as an ingredient in cookies in different concentrations is evaluated, in this way, waste can be reduced in addition to taking advantage of nutrients, bioactive compounds, and dietary fiber from the peels. Carrot peels were collected, washed, dehydrated at 60°C for 24 hours, and then finely ground to obtain carrot peel flour (CPF). Cookies were developed with the incorporation of 0, 5, 10, and 20% of CPF in replacement of flour (Samples CZ0, CZ5, CZ10, and CZ20 respectively). The preference and sensory acceptability of the cookies samples were evaluated using an an-Ranking test and a 9-point Hedonic Scale by parameters (appearance, color, aroma, flavor, texture, general acceptability) respectively. The satiety produced by its consumption was also evaluated through the "Satiety Quotient" (SQ) which uses the Visual Analog Scale (VAS) to quantify the state of satiety at different times. The dietary fiber (DF) content in the CPF and in the cookies samples was determined by the enzymatic-gravimetric method. The results showed that the CZ20 sample achieved the first sensory preference and the highest sensory acceptability in a significant way (p<0.05). The incorporation of CPF in cookies produced an increase in the content of dietary fiber and SQ. Based on the results obtained, it was concluded that the best option turned out to be the cookie with 20% CPF, since sensorially it is the most preferred and most acceptable, contains more dietary fiber and causes more satiety than the other samples.

RESUMO

Background: Apple pomace is a by-product of the fruit juice industry and comprises peel, seed, stem, and pulp tissues. This by-product contains dietary fibers, polyphenols, vitamins, and organic acids that can benefit human health and have a high potential as a dietary source. Baked products are well-known food types to humans and have a key role in feeding people worldwide. Nowadays, enriched products such as bread, cakes, and biscuits are available in stores. Different studies worldwide have been done about applying the by-products of the fruit juice industry in the bakery. Objective: This research aimed to evaluate apple peel (APE) and pulp (APU) powders separately as a partial substitute for wheat flour in cake production. Methods: Apple peel and pulp separately produced as the residual wastes of juicing were dried for 3 hours in oven (60°C). The dried pulp and peel were ground and sieved using a 60 µm mesh. In this research, chemical and physicochemical analyses were performed according to AACC (Approved Methods of the American Association of Cereal Chemists) and standard food analysis methods. Textural characteristic was analyzed by a texture analyzer (Brookfield CT3-10 Kg, US) equipped with an aluminum probe. Results: Different levels of APE and APU powders (10%, 20%, and 30 %) were used to enrich the cakes. The ash content, fat content, water adsorption capacity, and oil absorption capacity of the wheat flour were lower than APU and APE, whereas the moisture content, protein content, bulk density, and pH showed a reverse trend. Adding APU and APP to the cake formula increased total dietary fiber (TDF) from 4.14 % in the control sample to 27.71 % in the sample with 30 % apple peel powder (APE-30). The highest a* colorimetric parameter (redness) in the cake core was 3.82 in the APE-30 sample. The addition of APE and APU significantly increased the hardness, gumminess, and chewiness of the samples (p<0.05). APE-10 samples could improve the nutritional properties of the cakes without significant reduction (p>0.05) in overall acceptance compared to the control sample. Conclusion: The results of this research demonstrated that a partial replacement of the wheat flour with apple pulp and peel significantly increased the dietary fibers, especially insoluble dietary fiber, compared to the control sample. Apple pulp and apple peel powders had the potential for use in cake making as a good source of dietary fibers

ABSTRACT Chia (Salvia hispanica L.) is a seed native to the southern part of Mexico and Guatemala, which has spread to other Latin American countries. This seed has been used for different purposes throughout history, where it stands out as a food product due to its great versatility, since it can be used as a seed, whole meal flour, fiber and/or protein fractions and oil. Currently, the investigation of new food sources that provide health benefits has managed to collect information on the chemical composition and nutritional value of this seed and its derivatives (flour and oil). For polyunsaturated fatty acid content, n-3 is found, highlighting alpha linolenic acid (C18:3n-3, ALA), which is proposed as an alternative source of this nutrient to foods of other origins. In addition, the fiber content of chia, is mainly insoluble fiber. Regarding the benefits associated with chia consumption, it is closely related to chronic non-communicable diseases such as dyslipidemia, diabetes, type II, hypertension, cancer, among others, managing to attract the attention of researchers to control and prevent these pathologies that are increasing in world population. Therefore, it is relevant to deepen the knowledge available about this seed and its by-products in order to establish the possible molecular mechanisms that are involved in generating health benefits. The objective of this review is to present an update on the benefits associated with consumption of chia seed and its derivatives.

RESUMO

This study developed a palatable, acceptable, and functional mixed juice of pineapple (Ananas comosus var. Comosus), passion fruit (Passiflora edulis flavicarpa degener), and yacon (Smallanthus sonchifolius), with enhanced bioactive and prebiotic compounds. The ideal proportion of fruit and yacon was derived after planning a mixture with six formulations and by evaluating their bioactive compounds and organic acid profile. The best formulation sensory evaluation was performed by the Just-About-Right test (JAR) and global acceptance. The chosen mixed juice (M6 - 30% pineapple, 45% passion fruit, and 30% yacon) presented results that showed elevated levels of antioxidant activity (82.5% DPPH* inhibition), carotenoids (0.97 mg.100g-¹), and total polyphenols (70.28 mg.100g-¹). Total flavonols (23.95 mg.100g-¹), total anthocyanins (1.37 mg.100g-¹), gallic acid (3.13 µg.mL-¹), quercetin (2.25 µg.mL-¹), syringic acid (1.01 µg.mL-¹), citric acid (949.30 mg.100g-¹), malic acid (140.35 mg.100g-¹), and 0.58% of dietary fiber were also reported. Sensorially, consumers perceived high acidity, strong flavor, and a fibrous texture, which might have affected the global acceptance of the juice (6.0).

RESUMO

The objective of this work was to develop cookies using sorghum, germinated millet and chia flours. Four formulations (F) were used: F-sorghum (100% sorghum flour); F-Sorghum + chia (50% sorghum flour and 50% chia flour), F-millet (100% millet flour) and F-millet + chia (50% millet flour and 50% chia flour). The germinated millet flour was submitted to microbiological analysis. All cookies were evaluated in relation to chemical and sensory analyses, according to AOAC and hedonic nine-point scale, respectively. The statistical analysis was performed by the variance analysis and Tukey test at 5% probability. The F-millet formulation showed the least humidity content (4.59 ± 0.25g/100g), while chia containing cookies showed lesser concentrations of carbohydrates (F-sorghum + chia: 44.35 ± 4.34g/100g and F-millet + chia: 41.03 ± 1.40g/100g) and higher ash content (F-sorghum + chia: 3.80 ± 0.02g/100g and F-millet + chia: 3.42 ± 0.24g/100g) and of protein (F-sorghum + chia: 15.38 ± 0.44 g/100g and F-millet + chia: 18.06 ± 0.53 g/100g). The caloric value and the lipids content did not differ among formulations. The sensory analysis had 57 evaluators. The cookies produced with chia and germinated millet had higher rates for flavor, texture and general impression. In general, all tested biscuits had good sensory acceptance and nutritional quality being an alternative to increase the consumption of bioactive compounds and antioxidants(AU)

RESUMO

ABSTRACT BACKGROUND: Diverticulitis is an acute inflammatory process that affects individuals with diverticular disease. Given the sharp increase in the diagnostic rate of such a pathological process, there was also an increased interest in elucidating the possible causes related to the development of this clinical condition. Among the main factors investigated, diet excels, the object of study of this integrative literature review. METHODS: After searching the virtual health library and PubMed databases, five prospective cohort studies were selected that best answered the guiding question: "Is there a relationship between diet and the incidence of diverticulitis?". RESULTS: It was observed that the high intake of red meat and the low intake of dietary fiber were the most strongly associated dietary factors with the incidence of this inflammatory process. CONCLUSION: Therefore, it is evident that choosing healthy eating habits can considerably reduce the incidence of diverticulitis and, consequently, potentially more serious complications directly related to it.

RESUMO CONTEXTO: A diverticulite é um processo inflamatório agudo que afeta indivíduos com doença diverticular. Diante do acentuado aumento da taxa diagnóstica desse processo patológico, também houve o aumento do interesse em elucidar as possíveis causas relacionadas ao desenvolvimento dessa condição clínica. Entre os principais fatores investigados, destaca-se a dieta; objeto de estudo desta revisão integrativa da literatura. MÉTODOS: Após pesquisa nas bases de dados da biblioteca virtual em saúde e PubMed, foram selecionados cinco estudos de coorte prospectivos que melhor responderam à questão norteadora "Há relação entre dieta e incidência de diverticulite?". RESULTADOS E CONCLUSÃO: Observou-se que o alto consumo de carnes vermelhas e o baixo consumo de fibra alimentar são os fatores dietéticos mais fortemente associados à incidência desse processo inflamatório. Fica evidente, portanto, que a escolha de hábitos alimentares saudáveis pode reduzir consideravelmente a incidência de diverticulite e, consequentemente, de possíveis complicações mais graves diretamente relacionadas a ela.

Objective: To design commercialized hamburger meat that contains chicken breast as the base, fiber, reduced fat, and is accepted by consumers. Materials and Methods: Three formulations were created with a standard hamburger base and additional fiber as a fat replacement: F1 contained fiber from citron (Sechium edule); F2, from carrots (Daucus carota); and F3 from inulin. The theoretical nutritional composition was calculated and a consumer acceptance test was performed on a scale of nine points. Results: The most accepted formulation by consumers with the highest fiber content was the hamburger containing inulin, rated at 7.7±1.4 points. According to the Dunett T3 test, significant differences were reached by F1 (p=0.000) and F2 (p=0.001). They also had similar acceptance averages: F1 (5.9±2.2 points; p=0,000) and F2 (6.0±2.5 points; p=0.001) (p=0.931). The formulations containing added fiber were lowest in fat and calories when compared to the control formulation. Conclusion: It is possible to achieve meat derivatives with reduced fat and added fiber that are sensorily accepted by consumers.

RESUMO

Foram determinados os valores energéticos e a composição bromatológica do resíduo seco de fecularia (RSF) para frangos de corte, na fase de crescimento, utilizando ou não enzimas carboidrases. Os tratamentos foram distribuídos em esquema fatorial 2x4 + ração referência, sendo uma RR sem adição de RSF e quatro tratamentos experimentais com 10%, 20%, 30% e 40% de inclusão do RSF e a suplementação ou não com carboidrases. A composição química encontrada para o RSF, na MN, foi de 89,86% de matéria seca, 0,98% de proteína bruta, 3519kcal kg-1 de energia bruta, 0,19% de extrato etéreo, 27% de fibra em detergente neutro, 19,5% de fibra em detergente ácido, 0,33% de cálcio, 0,43% de fósforo, 0,46% de potássio e 0,12% de magnésio. O uso de carboidrases proporcionou um aumento de 173 e 213kcal kg-1 nos valores de EMA e EMAn, respectivamente, resultando em 1828kcal kg-1 EMA e 1840kcal kg-1 EMAn. Concluiu-se que os maiores níveis de EMA e EMAn foram encontrados para o nível de inclusão médio do RSF de 35% e que a suplementação enzimática pode promover aumento desses parâmetros em até 12% em dietas para frangos de corte na fase de crescimento.(AU)

The energetic values and the bromatological composition of the dry residue of cassava (DRC) were determined for growing broilers with or without carbohydrase enzymes. The treatments were distributed in a 2x4 + reference diet factorial scheme, with one RD without addition of DRC and four experimental treatments with 10, 20, 30 and 40% inclusion levels of RSF and supplementation or not with carbohydrases. The chemical composition found for DRC in natural matter was 89.86% dry matter, 0.98% crude protein, 3519kcal kg-1 gross energy, 0.19% ether extract, 27% neutral detergent fiber, 19.5% of acid detergent fiber, 0.33% of calcium, 0.43% of phosphorus, 0.46% of potassium and 0.12% of magnesium. The use of carbohydrase resulted in an increase of 173 and 213kcal kg-1 in EMA and EMAn values, respectively, resulting in 1828kcal kg-1 EMA and 1840kcal kg-1 EMAn. It was concluded that the highest levels of AME and AMEn were found for the mean inclusion level of the DRC of 35% and that enzymatic supplementation may promote the increase of these parameters by up to 12% in broiler diets in the growth phase.(AU)
