Evidencias del efecto del grano integral en las enfermedades crónicas no transmisibles

Los cereales integrales son una categoría de alimentos fundamental para la dieta humana y representan una fuente invaluable de carbohidratos, proteínas, fibras, fitoquímicos, minerales y vitaminas. Muchos estudios han demostrado que el consumo de cereales integrales está relacionado con un menor riesgo de enfermedades crónicas no transmisibles. Sin embargo, varios de sus efectos positivos para la salud parecen desaparecer cuando se refinan los cereales. La pregunta de investigación es cuál sería el efecto de los cereales integrales en la prevención de enfermedades crónicas no transmisibles. Este artículo describe los efectos positivos del consumo de cereales integrales en la prevención de estas enfermedades. Para ello, se realiza una descripción narrativa que revisa los antecedentes disponibles sobre: a) situación epidemiológica en Chile y su relación con la alimentación; b) consumo de cereales integrales en el mundo y en Chile; y c) el efecto del consumo de cereales integrales en la reducción del riesgo de enfermedad cardiovascular. obesidad, diabetes tipo 2 y cáncer. Los antecedentes generales son muy alentadores sobre el efecto positivo del consumo de cereales integrales sobre determinadas enfermedades, especialmente las de origen metabólico. Sin embargo, la incertidumbre de algunas asociaciones negativas merece mayor atención.

Whole grains are a fundamental food category for the human diet and represent an invaluable source of carbohydrates, proteins, fibers, phytochemicals, minerals and vitamins. Many studies have shown that consumption of whole grains is linked to a lower risk of chronic non-communicable diseases. However, several of its positive health effects seem to disappear when grains are refined. The research question is what would be the effect of whole grains in the prevention of Chronic Non-Communicable Diseases. This article describes the positive effects of whole grain consumption in these diseases.To this end, a narrative description is made that reviews the available background on: a) epidemiological situation in Chile and its relationship with diet; b) consumption of whole grains in the world and in Chile; and c) the effect of whole grain consumption on reducing the risk of cardiovascular disease. obesity, type 2 diabetes, and cancer. The general background is very encouraging for a positive effect of whole grain consumption on certain diseases, especially those of metabolic origin. However, the uncertainty of some negative associations deserves further attention.

Validation and calibration of the Food Consumption Frequency Questionnaire for pregnant women

ABSTRACT BACKGROUND: Few food frequency questionnaires (FFQ) have been validated for pregnant women, particularly those in small- and medium-sized cities in different regions of Brazil. OBJECTIVES: To validate and calibrate a semiquantitative FFQ for pregnant women. DESIGN AND SETTING: The study was validated with a sample of 50 pregnant women (≥ 18 years) enrolled in Brazilian prenatal services. METHODS: An FFQ and a 24-hour recall were used to evaluate dietary intake. Dietary variables were tested for normality and log-converted when asymmetrical. Pearson's Correlation Coefficient was used to validate the questionnaire. Linear regression was applied to extract calibration factors. All variables underlying the consumption analysis were adjusted for energy. RESULTS: The mean age of the pregnant women was 26 years ± 6.2 years; 58% were in their first trimester, and 30% were identified as overweight/obese. The Pearson correlation analysis results indicated that the FFQ overestimated energy and nutrient intake, whose coefficients ranged from −0.15 (monounsaturated fat) to 0.50 (carbohydrate). Adjusting for energy reduced the mean values of intake coefficients, which now ranged from −0.33 (sodium) to 0.96 (folate). The calibration analysis results indicated variation in the coefficients from −0.23 (sodium) to 1.00 (folate). Calibration produced satisfactory coefficients for the FFQ compared with the reference standard for energy, macronutrients, monounsaturated fat, cholesterol, vitamins B12/C, folate, sodium, iron, and calcium. CONCLUSIONS: After validating and calibrating tests, we observed that the FFQ was adequately accurate for assessing the food consumption of the pregnant women in this study.

Insatisfação com a imagem corporal e baixa aderência ao padrão alimentar ocidental em escolares: um estudo transversal / Body image dissatisfaction and low adherence to the Western dietary standard among schoolchildren: a cross-sectional study

Resumo Este estudo objetivou identificar padrões alimentares e avaliar a associação entre percepção da imagem corporal e esses padrões em escolares. Um estudo transversal foi conduzido em 385 escolares (ambos os sexos, 10-17 anos de idade) de 4 escolas públicas de Salvador, Brasil. Dois recordatórios alimentares de 24h não consecutivos foram aplicados e o padrão alimentar foi determinado por Análise Fatorial Exploratória, após ajuste dos dados dietéticos pelo Multiple Source Method. Para avaliar percepção da imagem corporal, nós usamos uma escala brasileira de silhuetas. Avaliamos as associações entre percepção da imagem corporal e padrões alimentares usando o modelo de regressão logística politômica ajustado para covariáveis. Três padrões alimentares foram obtidos: "padrão ocidental", "padrão saudável" e "comidas típicas/junk food". Após ajuste, adolescentes que desejavam uma silhueta menor (2,48 [IC95%: 1,04-6,11], 3,49 [IC95%: 1,35-9,05] e 2,87 [IC95%: 1,13-7,26]) tinham mais chances de aderir aos quintis de menor consumo do padrão ocidental, comparados àqueles satisfeitos com sua imagem corporal. Nenhuma associação foi identificada nos outros dois padrões alimentares. Adolescentes insatisfeitos com seus corpos tendem a aderir menos a padrões alimentares não saudáveis.

Abstract This study aimed to identify dietary patterns and to evaluate the association between body image perception and these patterns among schoolchildren. A cross-sectional study was conducted on 385 schoolchildren (both sexes, 10-17 years old) from four public schools in Salvador, Brazil. Two non-consecutive 24-hour dietary recalls were applied, and the dietary pattern was determined by Exploratory Factor Analysis after adjustment of dietary data using the Multiple Source Method. To evaluate body image perception, the Brazilian body shape silhouette was used. The associations between body image perception and dietary patterns using the polytomous logistic regression model adjusted for covariables was assessed. Three dietary patterns were obtained: "Western standard," unhealthy, "healthy pattern" and "typical dishes/ junk food." After adjustment, adolescents who wished for a slimmer silhouette (2.48 [95%CI: 1.04-6.11], 3.49 [95%CI: 1.35-9.05] and 2.87 [95%CI: 1.13-7.26]) were more likely to adhere to the quintiles with the lowest consumption of the Western standard, compared to those satisfied with their body image. No associations were identified in the other two dietary patterns. Adolescents dissatisfied with their bodies tend to adhere less to unhealthy dietary patterns.

Association of dietary patterns and body phenotypes in Brazilian adolescents / Associação entre padrões alimentares e fenótipos corporais em adolescentes brasileiros

Abstract Objectives: to investigate the association between dietary patterns, physical activity, and body phenotypes in adolescents. Methods: this school-based cross-sectional study involved 1,022 adolescents aged ten to 19 years. Dietary patterns and body phenotypes were defined using a principal component analysis. Body phenotype was defined using anthropometry, body composition, biochemistry, sexual maturation, and dietary patterns from 19 food groups, using a food frequency questionnaire. The association between the dietary patterns and body phenotypes was assessed using a linear regression model. Results: five body phenotypes (BP1adiposity, BP2puberty, BP3biochemical, BP4muscular, BP5lipids_biochemical) and five dietary patterns (DP1ultraprocessed_foods, DP2fresh_foods, DP3bread_rice_beans, DP4culinary_preparations, DP5cakes_rice_beans) were identified. There were higher BP_adiposity scores for obese adolescents, but energy expenditure was similar for obese and non-obese adolescents. Physical activity was positively associated with BMI, BP_adiposity, and BP_puberty. We observed a negative association between DP_ultraprocessed_foods and BMI, and a positive association between DP_fresh_food. DP_fresh_foods was positively associated with BP_adiposity; DP_ultraprocessed_foods and DP_culinary_preparations were negatively associated with this phenotype. BP_biochemical was negatively associated with DP_fresh_foods. Conclusion: we identified a negative association between a dietary pattern composed mainly of ultra-processed foods, fresh foods, and BP_adiposity. These associations need to be better explored, especially in adolescents, as both dietary patterns and phenotypes were defined using multivariate analysis.

Resumo Objetivos: investigar associação entre padrão alimentar (PA), atividade física (AF) e fenótipos corporais (FC) em adolescentes. Métodos: estudo transversal de base escolar com 1.022 adolescentes de dez a 19 anos. Padrão alimentar e fenótipo corporal foram definidos por meio da análise de componentes principais. O fenótipo corporal foi definido usando antropometria, composição corporal, bioquímica e maturação sexual, e padrão alimentar a partir de 19 grupos de alimentos de um questionário de frequência alimentar. A associação entre padrão alimentar e fenótipo corporal foi avaliada por modelo de regressão linear. Resultados: foram identificados cinco fenótipos corporais (FC1adiposidade, FC2puberdade, FC3bioquímico, FC4muscular, FC5lipídios_bioquímico) e cinco padrões alimentares (PA1alimentos_ultraprocessados, PA2alimentos_frescos, PA3pão_arroz_feijão, PA4preparações_culinárias, PA5bolos_arroz_feijão). Há maiores escores de FC_adiposidade para adolescentes com obesidade, mas o gasto energético foi semelhante para adolescentes com e sem diagnóstico de obesidade. Atividade física associou-se positivamente com IMC, FC_adiposidade e FC_puberdade. Observamos associação negativa entre PA_ultraprocessados e IMC, e positiva entre PA_alimentos_frescos. PA_alimentos_frescos associou-se positivamente com FC_adiposidade; PA_ultraprocessados e PA_preparações_culinárias se associaram negativamente a este fenótipo. FC_bioquímico associou-se negativamente com PA_alimentos_frescos. Conclusão: identificamos associação negativa entre padrão alimentar composto principalmente por alimentos ultraprocessados e alimentos in natura e FC_adiposidade. Essas associações devem ser exploradas com o mesmo público em estudos futuros, principalmente em adolescentes, pois tanto o padrão alimentar quanto o fenótipo foram definidos por meio de análise multivariada.

Escenarios lácteos y microbiota intestinal en los primeros 1000 días / Milk scenarios and gut microbiota in the first 1000 days of life

La leche humana es el estándar de oro para la nutrición del bebé y debe iniciarse en la primera hora de vida. La leche de vaca, de otros mamíferos o las bebidas vegetales no se deben ofrecer antes del año de vida. Sin embargo, algunos niños requieren, al menos en parte, de fórmulas infantiles. Aun con las sucesivas mejoras a lo largo de la historia mediante la incorporación de oliogosacáridos, probióticos, prebióticos, sinbióticos y postbióticos, las fórmulas infantiles siguen siendo perfectibles para reducir la brecha de salud entre los bebés amamantados y aquellos alimentados con fórmula. En este sentido, se espera que la complejidad de las fórmulas siga aumentando a medida que se conozca mejor cómo modular el desarrollo de la microbiota intestinal. El objetivo de este trabajo fue realizar una revisión no sistemática del efecto de los diferentes escenarios lácteos sobre la microbiota intestinal.

Human milk is the gold standard for infant nutrition, and breastfeeding should be started within the first hour of life. Cow's milk, other mammalian milk, or plant-based beverages should not be offered before 1 year of age. However, some infants require, at least in part, infant formulas. Even with subsequent enhancements throughout history, with the addition of oligosaccharides, probiotics, prebiotics, synbiotics, and postbiotics, infant formulas still have room for improvement in reducing the health gap between breastfed and formula-fed infants. In this regard, the complexity of infant formulas is expected to continue to increase as the knowledge of how to modulate the development of the gut microbiota is better understood. The objective of this study was to perform a non-systematic review of the effect of different milk scenarios on the gut microbiota.

Efectividad del uso de la entrevista motivacional en la consulta de nutrición sobre el riesgo cardiometabólico de pacientes con trastorno bipolar / Effectiveness of the motivational interviewing on cardiometabolic indicators of patients with bipolar disorder

Resumen El propósito de este trabajo fue evaluar la efectividad de la entrevista motivacional en la consulta de nutrición sobre indicadores de riesgo cardiometabólico en pacientes con trastorno bipolar. Se realizó un estudio experimental en que el grupo control recibió orientación nutricional basada en planes de alimentación y el grupo de intervención recibió consulta nutricional incorporando los principios y habilidades de la entrevista motivacional. Los participantes fueron seguidos por tres meses y se realizaron evaluaciones de hábitos alimenticios, actividad física, riesgo cardiometabólico, composición corporal y calidad de vida. El grupo de entrevista motivacional redujo el consumo de carnes (B=-0.45, p=0.032) y embutidos (B=-0.60, p=0.002). Asimismo, la presión arterial diastólica (B=-6.97, p=0.029) y glucemia (B=-9.27, p=0.097) de estos pacientes tendieron a disminuir. La entrevista motivacional promueve cambios que pueden hacer una diferencia clínica; aun en reducidos periodos de tiempo. Los nutriólogos capacitados para su implementación disponen de una herramienta adicional para el manejo de comorbilidad cardiometabólica en población vulnerable.

Abstract The purpose of this work was to assess the effectiveness of the motivational interviewing in the nutrition consultation on indicators of cardiometabolic risk in patients with bipolar disorder. An experimental study was conducted in which the control group receives nutritional guidance based on feeding plans and the intervention group received nutritional consultation incorporating the principles and skills of the motivational interviewing. Participants were followed by three months and evaluations of eating habits, physical activity, cardiometabolic risk, body composition and quality of life were carried out. The motivational interviewing group reduced the consumption of meats (B=-0.45, p=0.032) and sausages (B=-0.60, p=0.002). Likewise, the diastolic blood pressure (B=-6.97, p=0.029) and glycemia (B=-9.27, p=0.097) of these patients tended to decrease. Motivational interviewing promotes changes that can make a clinical difference, even in short periods of time. Nutritionists trained for its implementation have an additional tool for the management of cardiometabolic comorbidity in a vulnerable population.

Hábitos alimentarios asociados a la emergencia sanitaria Covid-19 en adultos chilenos / Eating habits associated with the Covid-19 health emergency in Chilean adults

Introducción. El brote de COVID-19 generó cambios significativos en los hábitos alimentarios asociados a las medidas de confinamiento y distanciamiento social. Objetivo. Evaluar los hábitos alimentarios asociados a la emergencia sanitaria COVID-19 en adultos chilenos durante el año 2020. Materiales y Métodos. Se realizó un estudio observacional, descriptivo y transversal en adultos chilenos seleccionados mediante muestreo no probabilístico por conveniencia. Se utilizó una encuesta validada por juicio de expertos, que incluyó preguntas sobre características sociodemográficas, ingesta habitual de alimentos y percepción de cambios de hábitos alimentarios durante el confinamiento. Resultados. Participaron 4.346 adultos chilenos con una edad promedio de 35,8 ± 13,9 años, predominantemente residentes urbanos (94,3%) y mujeres (75,1%). Se observó un aumento en el abastecimiento de alimentos en los hogares durante el confinamiento. La mayoría de los participantes manifestó que mantuvo o aumentó el consumo de verduras, frutas, lácteos, pescado y legumbres. Sin embargo, la ingesta de alimentos saludables no alcanzó las recomendaciones nutricionales establecidas. Adicionalmente, se encontró un aumento en el consumo de dulces. Conclusiones. Este estudio revela los efectos del confinamiento por la pandemia de COVID-19 en los hábitos alimentarios de los adultos chilenos, donde un porcentaje considerable de la población no cumplió con las recomendaciones de una dieta equilibrada según las guías alimentarias chilenas. El aumento en el consumo de algunos alimentos poco saludables puede tener implicaciones en la salud y el estado nutricional. Es necesario fomentar una alimentación equilibrada durante situaciones de crisis como esta pandemia(AU)

Introduction. The COVID-19 outbreak has led to significant changes in dietary habits due to confinement and social distancing measures. Objective. To assess the dietary habits associated with the COVID-19 health emergency among Chilean adults during the year 2020. Materials and methods. An observational, descriptive, and cross- sectional study was conducted on Chilean adults selected through non-probabilistic convenience sampling. A survey validated by expert judgment was used, including questions on sociodemographic characteristics, usual food intake, and perceived changes in dietary habits during confinement. Results. A total of 4,346 Chilean adults participated in the study, with an average age of 35.8 ± 13.9 years, predominantly urban residents (94.3%), and female (75.1%). An increase in household food supplies during confinement was observed. Most participants reported maintaining or increasing their consumption of vegetables, fruits, dairy, fish, and legumes. However, the intake of healthy foods did not meet the established nutritional recommendations. Additionally, there was an increase in the consumption of sweets. Conclusions. This study reveals the effects of COVID-19 confinement on the dietary habits of Chilean adults, where a considerable percentage of the population did not comply with the recommended balanced diet according to Chilean dietary guidelines. The increased consumption of some unhealthy foods may have implications for health and nutritional status. It is essential to promote balanced eating during crisis situations like this pandemic(AU)

Calidad de los Carbohidratos en la dieta de la población urbana costarricense / Carbohydrate Quality in the diet of the Costa Rican urban population

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)

Sostenibilidad alimentaria y prevalencia de consumo de preparaciones tradicionales y típicas en hogares del centro-sur de Chile / Food sustainability and prevalence of consumption of traditional and typical preparations in households in central-southern Chile

Introducción. Las preparaciones tradicionales típicas incluyen ingredientes mínimamente procesados, provenientes de la agricultura local, raíces y tradiciones de un territorio. A nivel mundial la población ha cambiado sus patrones dietéticos, incorporando alimentos ultraprocesados impactando la salud poblacional y planetaria. Objetivo. Identificar la sostenibilidad y la prevalencia de consumo de preparaciones tradicionales típicas chilenas en hogares de una región de la zona centro-sur de Chile. Materiales y Métodos. Diseño transversal descriptivo, con una muestra de 104 hogares mediante muestreo no probabilístico por conveniencia. Se identificó la sostenibilidad de 34 preparaciones tradicionales típicas chilenas, aplicando el sistema NOVA de clasificación de los alimentos según grado y tipo de procesamiento. Las preparaciones se clasificaron en sostenibles (>60% de ingredientes del grupo 1), medianamente sostenibles (50-60%) y no sostenibles (<50%). El estudio contó con la aprobación del Comité de Bioética de la Universidad del Bío-Bío. El análisis de datos consideró frecuencias, porcentajes e IC95% en STATA 17.0. Resultados. El 64% de las preparaciones fueron clasificadas como sostenibles, el 23% medianamente sostenibles y un 13% como no sostenibles. Las preparaciones sostenibles son las más consumidas por los hogares, especialmente aquellas que incluyen legumbres. Las preparaciones no sostenibles consumidas en los hogares se basan en harina refinada, manteca vegetal hidrogenado y/o aceites. Conclusiones. La sostenibilidad de las preparaciones tradicionales típicas chilenas depende de sus ingredientes. Las preparaciones sostenibles son las más consumidas por los hogares de esta región, y se basan en alimentos naturales o poco procesados(AU)

Introduction. Typical traditional preparations include minimally processed ingredients from local agriculture, roots and traditions of a territory. Globally, the population has changed its dietary patterns, incorporating ultra-processed foods, impacting population and planetary health. Objective. To identify the sustainability and prevalence of consumption of typical Chilean traditional preparations in households in central-southern Chile. Materials and Methods. Descriptive cross-sectional design, with a sample of 104 households using non-probabilistic convenience sampling. The sustainability of 34 typical Chilean traditional preparations was identif ied, applying the NOVA food classif ication system according to degree and type of processing. The preparations were classif ied as sustainable (>60% of group 1 ingredients), moderately sustainable (50- 60%) and non-sustainable (<50%). The Bioethics Committee of the Universidad del Bío-Bío approved the study. Data analysis considered f requencies, percentages and 95%CI in STATA 17.0. Results. 64% of the preparations were classif ied as sustainable, 23% moderately sustainable, and 13% non-sustainable. Sustainable preparations are the most consumed by households, especially those that include pulses. Unsustainable preparations households consume are based on ref ined flour, hydrogenated vegetable shortening and/or oils. Conclusions. The sustainability of typical Chilean traditional preparations depends on their ingredients. Sustainable preparations are the most consumed by households in this region and are based on natural or minimally processed foods(AU)

Evaluación de ingesta dietética en un grupo de mujeres lactantes en dos poblaciones de Antioquia, Colombia, 2021-2022 / Dietary intake assessment in a group of breastfeeding women in two populations of Antioquia, Colombia, 2021-2022

Objetivos: Describir la prevalencia del riesgo de deficiencia o exceso en la ingesta de nutrientes y el patrón de consumo de alimentos de acuerdo con las recomendaciones establecidas por el Ministerio de Salud y Protección Social y el Instituto Colombiano de Bienestar Familiar. Materiales y métodos: Se realizó un estudio transversal descriptivo en mujeres sanas que fueron atendidas en dos hospitales del oriente antioqueño, con seguridad alimentaria y nutricional (SAN) según la Escala Latinoamericana y Caribeña de Seguridad Alimentaria (ELCSA), en el primer trimestre de lactancia, evaluadas entre los años 2021 y 2022. La fuente de información fue la historia clínica. Se midieron las características sociodemográficas, clínicas, antropométricas y la ingesta dietética y de micronutrientes. Se empleó estadística descriptiva. Se presenta la prevalencia de déficit o exceso de ingesta calórica y el índice de relación de consumo (IRC). Se utilizaron los software EVINDI v5, PC-SIDE v1.0, Stata 16.1 y Jasp 0.16.4. Resultados: Se incluyeron 30 mujeres lactantes. La prevalencia de riesgo de deficiencia en la ingesta usual de energía fue 43 % y exceso 16 %; el riesgo de deficiencia proteica fue 98 %. El consumo superior al valor de referencia para grasa saturada fue 86 % y carbohidratos simples 72 %. El patrón de consumo se caracterizó por superar las recomendaciones para azúcares (IRC = 1,29), leche y derivados (IRC = 1,09), cereales, raíces, plátanos y tubérculos (IRC = 1,04). No cumplieron las recomendaciones en la ingesta de grasas (IRC = 0,70), carnes, huevos, leguminosas, frutos secos y semillas (IRC = 0,49), frutas y verduras (IRC = 0,41). Conclusiones: El patrón alimentario identificado dista de las guías nacionales, lo que limita el consumo de macro y micronutrientes, y contribuye al círculo intergeneracional de la malnutrición. Es fundamental realizar nuevas investigaciones en el país para identificar otros patrones de consumo e impulsar acciones de política al respecto.

Objectives: To describe the prevalence of the risk of under or overnutrition and the food intake pattern vis á vis the recommendations of the Ministry of Health and Social Protection and the Colombian Family Welfare Institute. Material and methods: Descriptive cross-sectional study carried out in healthy women receiving care in two hospitals of eastern Antioquia, with food and nutrition security in accordance with the Latin American and Caribbean Food Security Scale (ELCSA), in the first trimester of breastfeeding, assessed between 2021 and 2022. The clinical record was used as the source of information. The sociodemographic, clinical, anthropometric characteristics, as well as dietary and micronutrient intake, were measured. Descriptive statistics were used. The prevalence of deficient or excessive energy intake and the food consumption score (FCS) are presented. The EVINDI v5, PC-SIDE v1.0, Stata 16.1 and Jasp 0.16.4 software packages were used. Results: Overall, 30 breastfeeding women were included. The prevalence of the risk of deficient energy intake was 43 %, while the risk of excessive intake was 16 % and the risk of protein deficiency was 98 %. Intake exceeding the reference value for saturated fats was 86 %, and 72 % for simple carbohydrates. The consumption pattern was characterized by exceeding the recommendations for sugars (FCS = 1.29), milk and dairy products (FCS = 1.09), grains, roots, plantains and tubers (FCS = 1.04). Recommendations for the intake of fats (FCS = 0.70), meats, eggs, legumes, nuts, seeds (FCS = 0.49), fruits and vegetables (FCS = 0.41) were not met. Conclusions: The food intake pattern identified is far from meeting the national guidelines, limiting macro and micronutrient intake and contributing to the intergenerational malnutrition cycle. Additional research in the country is essential in order to identify other intake patterns and drive political action.

La pandemia de COVID-19 y el cumplimiento de las guías alimentarias en una comunidad universitaria de Chile / COVID-19 pandemic and adherence to food- based dietary guidelines in a Chilean university community

Introducción. La pandemia de SARS-CoV-2/COVID-19 y las restricciones sanitarias afectaron la disponibilidad, acceso y consumo de alimentos, impactando la alimentación y el estado nutricional. Objetivo. Determinar el efecto de la pandemia SARS-CoV-2/COVID-19 sobre el cumplimiento de las Guías Alimentarias Basadas en Alimentos de Chile, en una comunidad universitaria, antes y durante la pandemia. Materiales y métodos. Estudio de cohorte retrospectiva con 427 participantes. Se aplicó una encuesta online con preguntas basadas en los mensajes de las GABA.

Introduction. The SARS-CoV-2/COVID-19 pandemic, as well as health restrictions, impacted food availability, access and consumption, affecting dietary habits and nutritional status. Objective. To determine the effect of the SARS-CoV-2/ COVID-19 pandemic on the adherence to Chilean Food-Based Dietary Guidelines, within a university community, both before and during the pandemic. Materials and methods. A retrospective cohort study involving 427 participants was conducted. An online survey was administered, with questions based on the FBDGs' messages. The survey was validated through expert judgment and psychometric analysis, and agreement was assessed using the Kappa statistic (K = 89.95) while reliability was determined using the Cronbach's Alpha coefficient ( = 0.97). The period before the pandemic was defined as the time prior to March 2020, and the pandemic period was set between March 2020 and October 2021. Changes before and during the pandemic were measured using the symmetry test, considering a p value of <0.05 and a 95% confidence level, using the STATA 16 statistical software. Results. Statistically significant changes were observed before and during the pandemic in messages related to nutritional status (p = 0.000), weekly consumption of bakery products (p = 0.0040), cold meats (p = 0.0034), fried foods (p = 0.0070), legumes (p = 0.0000), water (p = 0.0000), and messages related to reading and nutrition information of products (p = 0.0000). Conclusions. The pandemic led to dietary changes in relation to FBDGs messages. Food policies and food and nutrition education strategies are required to address health emergency contexts(AU)

Dietary patterns associated with physical activity and sedentary behavior in university students in Mexico

Dietary patterns (DPs) are conditioned by a large number of factors, including physical activity and sedentary lifestyle, however, there is limited information on their interaction. This study aimed to identify DPs and their associations with physical activity and sedentary behavior among university students from Mexico. We conducted a cross-sectional, observational and analytical study. The participants were university students from Southwest Mexico. A total of 419 participants who did not suffer from any disease that affects oral nutrition or that prevented them from performing physical activity were included. DPs were generated from a principal component analysis and associations were analyzed using a logistic regression model. Three DPs were identified: "western", "prudent" and "traditional". The traditional pattern was significantly associated with high physical activity (OR: 2.78; 95% CI: 1.34-5.75) and was a protective factor against sedentary lifestyle (OR: 0.35; 95% CI: 0.13-0.93). The results show that a high physical activity and a lower sedentary lifestyle were associated with a healthier dietary pattern in the study population. It is important to implement interventions towards nutrition, physical activity and sedentary behavior for the population being studied.

Los patrones dietéticos están condicionados por una gran cantidad de factores, entre ellos la actividad física y el sedentarismo, sin embargo, existe poca información sobre su interacción. Este estudio tuvo como objetivo identificar patrones dietéticos y sus asociaciones con la actividad física y el comportamiento sedentario entre estudiantes universitarios del suroeste de México. Se trata de un estudio transversal, observacional y analítico. Los participantes fueron estudiantes universitarios del suroeste de México. Se incluyeron un total de 419 participantes que no padecían alguna enfermedad que condicionara su nutrición oral, ni condición que les impidiera realizar actividad física. Se realizó un análisis de componentes principales para determinar los patrones dietéticos, mientras que se utilizó un modelo de regresión logística para verificar las asociaciones. Se identificaron tres patrones dietéticos: "occidental", "prudente" y "tradicional". El patrón tradicional se asoció significativamente con actividad física elevada (OR: 2,78; IC 95%: 1,34-5,75) y fue un factor protector contra el sedentarismo (OR: 0,35; IC 95%: 0,13-0,93). Los resultados muestran que una alta actividad física y un menor sedentarismo se asociaron con un patrón dietético más saludable en la población de estudio. Es importante implementar intervenciones hacia la nutrición, la actividad física y el sedentarismo para la población en estudio.

Efectividad de la administración de hierro en forma semanal y diaria para la prevención de anemia por deficiencia de hierro en lactantes / Effectiveness of weekly and daily iron administration for the prevention of iron deficiency anemia in infants

Introducción. La deficiencia de hierro (DH) es la carencia nutricional más prevalente y la principal causa de anemia en lactantes. Existe consenso en la suplementación diaria con hierro como estrategia de prevención; también se demostró que la suplementación semanal es eficaz, pero la evidencia en lactantes es escasa. El objetivo fue comparar la efectividad de la administración diaria de hierro frente a la semanal para la prevención de la anemia por DH del lactante. Población y métodos. Ensayo clínico controlado y aleatorizado. Lactantes atendidos en un centro de salud público, sin anemia a los 3 meses de edad, aleatorizados en tres grupos: suplementación diaria (1 mg/kg/día), semanal (4 mg/kg/semana) o sin suplementación (grupo control con lactancia materna exclusiva [LME]). Se evaluó anemia y DH a los 3 y 6 meses. Se registró grado de adherencia y efectos adversos. Los datos se analizaron con el software R versión 4.0.3. Resultados. Participaron 227 lactantes. A los 6 meses el grupo de lactantes con LME sin suplementación (control) presentó prevalencias de DH y anemia por DH (ADH) mayores que los grupos intervenidos (diario y semanal). DH: 40,5 % vs. 13,5 % y 16,7 % (p = 0,002); ADH: 33,3 % vs. 7,8 % y 10 % (p < 0,001). No hubo diferencias entre los grupos diario y semanal. Tampoco hubo diferencias en el porcentaje de alta adherencia a la suplementación (50,6 % diaria vs. 57,1 % semanal), ni en los efectos adversos. Conclusiones. No se hallaron diferencias significativas en la efectividad entre la administración diaria y semanal para la prevención de ADH del lactante.

Introduction. Iron deficiency (ID) is the most prevalent nutritional deficiency and the main cause of anemia in infants. There is consensus on daily iron supplementation as a preventive strategy; and weekly iron supplementation has also been shown to be effective, but evidence in infants is scarce. The objective of this study was to compare the effectiveness of daily versus weekly iron administration for the prevention of ID anemia (IDA) in infants. Population and methods. Randomized, controlled clinical trial. Infants seen at a public health center, without anemia at 3 months of age, were randomized into 3 groups: daily supplementation (1 mg/kg/ day), weekly supplementation (4 mg/kg/week), or no supplementation (control group with exclusive breastfeeding [EB]). Anemia and ID were assessed at 3 and 6 months old. Adherence and adverse events were recorded. Data were analyzed using the R software, version 4.0.3. Results. A total of 227 infants participated. At 6 months, the group of infants with EB without supplementation(control) had a higher prevalence of ID and IDA than the intervention groups (daily and weekly). ID: 40.5% versus 13.5% and 16.7% (p = 0.002); IDA: 33.3% versus 7.8% and 10% (p < 0.001). There were no differences between the daily and weekly supplementation groups. There were also no differences in the percentage of high adherence to supplementation (50.6% daily versus 57.1% weekly) or adverse events. Conclusions. No significant differences in effectiveness were observed between daily and weekly administration for the prevention of infant IDA.

Programa Nacional de Suplementação de Ferro nos primeiros mil dias de vida em Salvador (BA) / National Iron Supplementation Program in the first thousand days of life in Salvador (BA) / Programa Nacional de Suplementación de Hierro en los primeros mil días de vida en Salvador, Bahía

Os primeiros mil dias de vida correspondem ao período desde a concepção até os primeiros dois anos após o nascimento. Durante essa fase, as necessidades nutricionais são elevadas devido às aceleradas alterações fisiológicas inerentes ao período, e o ferro está entre os micronutrientes mais requisitados. Considerando que a anemia, em especial por deficiência de ferro, é um problema de saúde pública, principalmente nessa fase da vida, foi instituído em 2005 o Programa Nacional de Suplementação de Ferro (PNSF). No entanto, há uma lacuna de estudos que analisam sua execução em municípios da Bahia. Por esse motivo, este estudo observacional descritivo objetivou avaliar a cobertura real do PNSF entre gestantes e crianças de 6 a 24 meses de vida, público-alvo do programa, no município de Salvador (BA), entre os anos de 2017 e 2022, a partir da análise de dados secundários disponibilizados pelo Ministério da Saúde. A cobertura real do PNSF ocorreu de forma insatisfatória no município, alcançando quantidades inferiores a 7% das gestantes e 1% das crianças, entre os anos de 2019 e 2021, e valores iguais a 0% para ambos os grupos nos anos de 2017, 2018 e 2022. Tais resultados podem ser motivados por diferentes fatores, como problemas operacionais na gestão/monitoramento do programa e/ou a baixa adesão da população. Destaca-se, assim, a necessidade da constante avaliação do desempenho do PNSF no intuito de identificar suas limitações e propor melhorias em sua execução.

The first thousand days of life correspond to the period from conception to the first two years after birth. During this phase, nutritional needs are high due to the accelerated physiological changes inherent to the period, and iron is among the most required micronutrients. Considering that anemia, especially due to iron deficiency, is a public health problem, especially at this stage of life, the National Iron Supplementation Program (PNSF) was instituted in 2005. However, there is a lack of studies that analyze its execution on municipalities in Bahia (BA). For this reason, this descriptive observational study aimed to evaluate the coverage of the PNSF among pregnant women and children between 6 and 24 months of life, the target audience of the program, in the municipality of Salvador (BA), between 2017 and 2022, based on the analysis of secondary data provided by the Ministry of Health. The actual coverage of the PNSF occurred unsatisfactorily in the municipality, reaching numbers below 7% of pregnant women and 1% of children, between the years 2019 and 2021, and values equal to 0% for both groups in the years 2017, 2018, and 2022. Such results can be due to different factors, such as operational problems in the management/monitoring of the program and/or the low adherence of the population. Thus, we highlight the need for constant evaluation of the PNSF performance to identify its limitations and propose improvements in its execution.

Los primeros mil días de vida corresponden al período que va desde la concepción hasta los primeros dos años después del nacimiento. Durante esta fase, las necesidades nutricionales son elevadas, debido a los cambios fisiológicos acelerados propios del período, y el hierro es uno de los micronutrientes más requeridos. Como la anemia, especialmente por deficiencia de hierro, es un problema de salud pública, especialmente en esta etapa de la vida, en 2005 se instituyó el Programa Nacional de Suplementación con Hierro (PNSF, por sus siglas en portugués). Sin embargo, faltan estudios que analicen su ejecución en municipios de Bahía (Brasil). Por esta razón, este estudio observacional descriptivo tuvo por objetivo evaluar la cobertura real del PNSF en mujeres embarazadas y en niños de entre 6 y 24 meses de vida, público objetivo del programa, en la ciudad de Salvador (Bahía), entre 2017 y 2022, con base en el análisis de datos secundarios proporcionados por el Ministerio de Salud. La cobertura real del PNSF se presentó de manera insatisfactoria en el municipio, alcanzando cifras inferiores al 7% de embarazadas y al 1% de niños, entre los años 2019 y 2021, con valores iguales al 0% para ambos grupos analizados en los años 2017, 2018 y 2022. Estos resultados pueden ser causados por diferentes factores, entre ellos, problemas operativos en la gestión/seguimiento del programa y/o baja adherencia de la población. Así, se destaca la necesidad de una evaluación constante del desempeño del Programa para identificar sus limitaciones y proponer mejoras en su ejecución.

Role of Dietary Management and Physical Activity in Control of Hypertension in Rural Areas of Punjab-A Cross-sectional Study

Introduction: As reported by WHO, hypertension is the third ‘killer’ disease, accounting for one in every eight deaths worldwide. Many modifiable and non-modifiable risk factors are found to be associated with the disease. The present study aims to determine the role of dietary management and physical activity in the control of hypertension in a given population. Material and Methods: A cross-sectional study was conducted that. Study included all hypertensive patients (290) from the field practice area of a tertiary care institute. A self-constructed, pretested questionnaire was used to enquire about the socio- demographic factors and other risk factors associated with hypertension. The data was analyzed using SPSS 23 and valid conclusions were drawn by using the chi-square test. Results: Out of 290 patients, 204 (70.3%) were females and 86 (29.7%) were males. Univariate analysis identified decreased salt intake, decreased fatty food consumption, physical activity, stress management, and spiritual help as highly significant factors affecting hypertension. On multivariate analysis, physical activity, stress management and spiritual help were found to be significant. Conclusion: The study showed that physical activity, stress management and spiritual help were significantly associated with hypertension control among the elderly. Measures should be taken to create awareness about lifestyle modifications in the control of hypertension.

Main results and public health implications of the National School Health Survey (ENSE), Colombia 2017

Introduction: The school population represents a fundamental group for health promotion actions, given that the foundations of healthy behaviors in adult life are established in children and adolescents, who can be greatly influenced by the school. Objective: To describe the health-related behavioral factors of schoolchildren between 13 and 17 years of age in secondary and middle school in Colombia. Methods: A national cross-sectional study was conducted (i.e., School Health Survey -ENSE-) that recorded information on dietary practices, physical activity, alcohol and drug consumption, injuries and bullying, and oral, visual and hearing health. Sampling was probabilistic, cluster and multistage. Results: Schoolchildren have low consumption of fruits, vegetables (13.1%) and dairy (76.5 %), high consumption of ultra-processed foods (82.4 %), sugary drinks (74.0 %) and fast foods (14.8 %), frequent addition of salt at the table (43.3 %), low compliance with physical activity recommendations (15.0 %) and high sedentary lifestyle (46.3 %), frequent consumption of alcohol (44.7 %) and psychoactive substances (14.7 %), in addition to prevalent situations of bullying (15.4 %), rejection (8.2 %) and verbal aggression (42.7 %). Conclusions: The ENSE shows critical inequalities by gender, ethnicity and social class, throughout the country. The indicators observed in schoolchildren are precursors of various chronic and degenerative diseases and mental illness, which requires the urgent attention of the different social actors in the country.

Introducción: La población escolar es un grupo fundamental para las intervenciones de promoción de la salud, ya que en los niños y adolescentes se sientan las bases de un comportamiento saludable en la vida adulta, que puede ser muy influenciado por la escuela. Objetivo: Describir los factores comportamentales relacionados con la salud de los escolares de 13 a 17 años de edad que cursan educación básica secundaria y media en Colombia. Métodos: Se realizó una encuesta nacional transversal (Encuesta de Salud en Escolares -ENSE-) con los lineamientos de Global School-based Student Health Survey para recolectar información sobre prácticas alimentarias, actividad física, consumo de alcohol y drogas, lesiones e intimidación, y salud bucal, visual y auditiva. El muestreo fue probabilístico, por conglomerados y polietápico. Resultados: Se incluyeron 79.640 escolares de 298 municipios. Los escolares presentaron bajo consumo de frutas, verduras (13.1%) y productos lácteos (76.5 %), alto consumo de alimentos ultraprocesados (82.4 %), bebidas azucaradas (74.0 %) y comidas rápidas (14.8 %); alto uso de sal añadida en la mesa (43.3 %), actividad física inferior a la recomendada (15.0 %) y sedentarismo (46.3 %). Fue frecuente el consumo de alcohol (44.7 %) y sustancias psicoactivas (14.7 %) y reportaron situaciones de intimidación (15.4 %), rechazo (8.2 %) y agresiones verbales (42.7 %). Conclusiones: La ENSE muestra desigualdades por género, etnia y clase social en todo el país. Los hallazgos observados en los escolares son factores de riesgo de enfermedades crónico-degenerativas y mentales, y requieren la atención urgente de los actores sociales del país.

A associação entre câncer colorretal e índice de qualidade nutricional (INQ); um estudo de caso-controle / The association between colorectal cancer and index of nutritional quality (inq); a case-control study

ABSTRACT Background: The nutritional quality of diet may influence the risk of colorectal cancer (CRC). This study compared the Index of Nutritional Quality (INQ) of various dietary components between colorectal cancer patients and healthy controls. Methods: A total of 480 participants were enrolled in the study (160 patients with colorectal cancer as a case group and 320 healthy control). An analysis was conducted on the general characteristics of the participants, their medical histories, anthropometric indicators, physical activity, alcohol consumption, reproductive history, smoking and food intake. A valid food frequency questionnaire was used to assess nutrient intake and INQ was calculated from daily nutrient intake. Results: A Significant inverse association was found between CRC and INQ for vitamins A (OR=0.01, CI: 0.01-0.01), K (OR=0.04, CI: 0.01-0.15), and B12 (OR=0.71, CI: 0.51-0.98), B5 (OR=0.43, CI: 0.00-0.01), zinc (OR=0.35, CI: 0.13-0.95), and phosphorus (OR=0.17, 0.19-0.94). The association between the INQ of vitamin B12 and zinc with colorectal cancer was disappeared after age adjustment. There was a significant negative association between CRC with the INQ of vitamins A, K, B5, phosphorus, and calcium after further adjustments for gender, BMI, menopausal status, and total energy intake. Conclusion: CRC is significantly associated with INQ for some micronutrients. INQ can be considered as an indicator to assess clinical nutritional problems.

RESUMO Contexto: A qualidade nutricional da dieta pode influenciar o risco de câncer colorretal (CCR). Este estudo comparou o Índice de Valor Nutricional (INQ) de vários componentes dietéticos entre pacientes com CCR e controles saudáveis. Métodos: Um total de 480 participantes foram inscritos no estudo (160 pacientes com CCR como um grupo de casos e 320 controles saudáveis). Uma análise foi conduzida sobre as características gerais dos participantes, seus históricos médicos, indicadores antropométricos, atividade física, consumo de álcool, histórico reprodutivo, tabagismo e ingestão de alimentos. Um questionário de frequência alimentar válido foi usado para avaliar a ingestão de nutrientes e o INQ foi calculado a partir da ingestão diária de nutrientes. Resultados: Associação significativa entre CCR e INQ para as vitaminas A (OR=0,00, IC: 0,00-0,01), K (OR=0,04, IC: 0,01-0,15), B12 (OR=0,71, IC: 0,51-0,98) houve uma associação negativa), B5 (OR=0,43, IC: 0,00-0,01), zinco (OR=0,35, IC: 0,13-0,95), fósforo (OR=0,17, IC: 0,19-0,94). A associação entre o INQ da vitamina B12, zinco e CCR desapareceu após o ajuste pela idade. Houve uma associação negativa significativa entre CCR e INQ de cálcio, e outros resultados não mudaram após ajustes adicionais para idade, gênero, Índice de Massa Corporal, estado de menopausa e ingestão total de energia. Conclusão: CCR está significativamente associado ao INQ para alguns micronutrientes. O INQ pode ser usado como um indicador para avaliar problemas nutricionais clínicos.

Fatores associados ao consumo de açúcares de adição de idosos da região de Campinas-SP, Brasil / Factors associated with added sugar consumption of older adults from the region of Campinas-SP, Brazil

Resumo A alimentação adequada tem profundo impacto na saúde dos idosos, e uma especial atenção deve ser dada ao consumo de açúcares de adição na dieta, que em excesso está associado a pior controle das doenças crônicas nesta fase. O objetivo do estudo foi avaliar a prevalência do consumo de açúcares de adição de idosos da região de Campinas-SP, seus fatores associados e suas principais fontes alimentares. Trata-se de estudo transversal realizado na região de Campinas-SP, com amostra de conveniência de 586 idosos. O consumo foi obtido por meio de dois recordatórios de 24 horas, sendo inadequado se >5% do consumo energético total. Também foi calculada a contribuição dos alimentos em relação ao teor total de açúcares. Considerou-se nível crítico de p<0,05. O consumo médio de açúcares de adição estava acima do recomendado (7,0%), inadequado em mais da metade da população estudada, sendo o açúcar de mesa e o mel as principais fontes dietéticas. A prevalência de inadequação do consumo foi maior entre mulheres (69,8%; p=0,004) e em indivíduos com baixo peso (83,7%; p=0,014), e o consumo foi menor em portadores de diabetes (47,8%; p<0,001). Os resultados apontam para que sejam elaboradas ações de saúde e nutrição a fim de garantir um consumo adequado de açúcares nesta fase.

Abstract Adequate nutrition has a profound impact on older adults' health. Therefore, special attention should be given to the dietetic intake of added sugars, which in excess is associated with poorer control of chronic diseases in this phase. The aim of the study was to evaluate the prevalence of consumption of added sugars in older adults in the Campinas-SP region, its associated factors, and its main dietary sources. A cross-sectional study was conducted in the region of Campinas-SP, with a convenience sample of 586 older individuals. Intake was obtained using two 24-hour food recalls, and values >5% of total energy consumption were considered inadequate. The contribution of the groups and foods in relation to the total content of sugars was also calculated. A critical level of p<0.05 was considered. The average intake of added sugars was higher than recommended (7.0%), and this inadequacy was observed in more than half of the sample, being table sugar and honey the main dietary sources. The prevalence of inadequate consumption was higher among women (69.8%; p=0.004) and individuals with low weight (83.7%; p=0.014), and lower in those with diabetes (47.8%; p<0.001). Results indicate that health and nutrition actions should be developed to ensure adequate sugar intake at this stage.

Harina de cáscara de zanahorias como ingrediente en la elaboración de galletas

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.
