ALULOSA COMO ENDULZANTE ALTERNATIVO PARA REDUCIR EL ÍNDICE GLUCÉMICO Y LAS CALORÍAS DE LOS ALIMENTOS: ASPECTOS BIOLÓGICOS, LEGALES Y TECNOLÓGICOS / ALLULOSE AS AN ALTERNATIVE SWEETENER TO REDUCE THE GLYCEMIC INDEX AND CALORIES OF FOODS: BIOLOGICAL, LEGAL AND TECHNOLOGICAL ASPECTS

La obesidad y la prevalencia de la diabetes han aumentado progresivamente en los últimos decenios, lo cual ha conllevado a diversas recomendaciones de la Organización Mundial de la Salud (OMS) para mejorar la dieta e incorporar hábitos saludables. Con el objetivo de limitar los azúcares agregados, reducir las calorías y modular la respuesta glucémica, la industria ha implementado distintas alternativas, entre las cuales ciertos azúcares raros presentan un gran potencial. La alulosa, como sustituto de azúcares tradicionales y edulcorantes, confiere características sensoriales similares a las de los productos con sacarosa y proporciona los beneficios nutricionales esperados. El objetivo de este trabajo fue revisar los conocimientos, hasta la fecha, sobre aspectos biológicos, legales y tecnológicos de la alulosa

The obesity and prevalence of type 2 diabetes have progressively increased in the recent decades, which has led to various recommendations from the World Health Organization (WHO) to improve diet and healthy habits. With the objective of limiting added sugars, reducing calories, and modulating the glycemic response, the industry has implemented different alternatives, among which certain rare sugars have great potential. Allulose as a substitute for traditional sugars and sweeteners confers sensory characteristics like those of products with sucrose and provides the expected nutritional benefits. The aim of this work was to look over the knowledge, to date, on biological, legal, and technological aspects of allulose

Scientific consensus on food sweeteners (2022) / 中华预防医学杂志

Sweeteners are a kind of food additives, which can give food a sweet taste with little or no energy and provide a variety of options for people who have sugar control needs. Due to their stable process performance and good safety, they have been widely used in food, pharmaceutical, and cosmetics industries worldwide in the past 100 years. The safety of sweeteners is based on strict food safety risk assessment, which has been affirmed by many international organizations, national/regional food safety risk assessment agencies and food safety management authorities. The proper use of sweeteners can provide sweetness, be beneficial to control energy intake, reduce the risk of dental caries, and provide more food choices for people with hyperglycemia or diabetes.

Riscos do consumo de edulcorantes para a saúde humana / Riscos do consumo de edulcorantes para a saúde humana

Pergunta: Quais são os riscos do consumo de edulcorantes para a saúde humana? Métodos: Após realização de protocolo de pesquisa, quatro bases da literatura eletrônica foram buscadas em maio de 2022, para identificar estudos que abordassem possíveis riscos do consumo de edulcorantes para a saúde humana. Utilizando atalhos de revisão rápida, foram realizadas seleção de revisões sistemáticas (RS), extração de dados e avaliação da qualidade metodológica com a ferramenta AMSTAR 2. Resultados: De 707 registros identificados nas bases de dados, 29 RS foram incluídas após processo de triagem e elegibilidade. As RS foram consideradas de confiança criticamente baixa (93,1%) e baixa (6,9%). Os desfechos analisados nos estudos se referem a eventos cardiovasculares (11 RS), peso corporal e outras medidas antropométricas (7 RS), neoplasias (7 RS), diabetes mellitus tipo 2 (5 RS), período gestacional (3 RS), doença renal (3 RS), mortalidade (2 RS), depressão ou alterações cognitivas (1 RS), doença hepática (1 RS), eventos gastrointestinais (1 RS), infertilidade masculina (1 RS). Uma RS também apresentou informações sobre eventos adversos. A maioria dos resultados indica que o consumo de edulcorantes e bebidas adoçadas artificialmente aumentou o risco de hipertensão arterial, diabetes, eventos cardiovasculares, como acidente vascular cerebral; mostrou-se associado a ganho de peso, aumento de outras medidas antropométricas e obesidade. O consumo de bebidas adoçadas artificialmente durante a gestação apresentou associação com parto prematuro, ganho de peso da gestante e do recém-nascido, além de possível risco para desenvolvimento de asma em crianças. A maioria dos resultados relacionados aos adoçantes artificiais e bebidas adoçadas artificialmente e bebidas dietéticas contendo adoçantes artificiais mostraram não haver uma associação com risco de cânceres. Observou-se associação com alguns tipos de câncer, porém se referem a poucos estudos de coorte ou caso-controle. Poucos estudos também apontam possível risco do consumo de bebidas adoçadas artificialmente para doença renal crônica e mortalidade por todas as causas, depressão e alterações hormonais e da microbiota intestinal com adoçantes artificiais. Não se constatou associação com infertilidade masculina e o consumo de ciclamato. Considerações finais: Em síntese, os resultados mais consistentes quanto ao risco do consumo de edulcorantes referem-se a eventos cardiovasculares, diabetes e parto prematuro, condições para as quais os estudos apontam inclusive uma relação dose-resposta. Além das lacunas do conhecimento, é importante considerar as falhas metodológicas da maioria das RS.

Question: What are the risks of consuming sweeteners to human health? Methods: After carrying out a research protocol, four databases from the electronic literature were searched in May 2022, to identify studies that addressed possible risks of the consumption of sweeteners to human health. Using rapid review shortcuts, selection of systematic reviews (SR), data extraction and methodological quality assessment were performed with the AMSTAR 2 tool. Results: Of 707 records identified in the databases, 29 RS were included after the screening and eligibility process. The SRs were considered critically low (93.1%) and low (6.9%) confidence. The outcomes analyzed in the studies refer to cardiovascular events (11 RS), body weight and other anthropometric measures (7 RS), neoplasms (7 RS), type 2 diabetes mellitus (5 RS), gestational period (3 RS), kidney disease (3 RS), mortality (2 RS), depression or cognitive impairment (1 RS), liver disease (1 RS), gastrointestinal events (1 RS), male infertility (1 RS). An SR also presented information on adverse events. Most of the results indicate that consumption of sweeteners and artificially sweetened beverages increased the risk of high blood pressure, diabetes, cardiovascular events such as stroke; was associated with weight gain, increase in other anthropometric measurements and obesity. The consumption of artificially sweetened beverages during pregnancy was associated with preterm birth, weight gain of the pregnant woman and the newborn, in addition to a possible risk for the development of asthma in children. Most of the results related to artificial sweeteners and artificially sweetened beverages and diet drinks containing artificial sweeteners showed no association with cancer risk. There was an association with some types of cancer, but they refer to few cohort or case-control studies. Few studies also point to a possible risk of consumption of artificially sweetened beverages for chronic kidney disease and all-cause mortality, depression and hormonal and intestinal microbiota changes with artificial sweeteners. There was no association with male infertility and consumption of cyclamate. Final considerations: In summary, the most consistent results regarding the risk of sweetener consumption refer to cardiovascular events, diabetes and premature birth, conditions for which studies even point to a dose-response relationship. In addition to knowledge gaps, it is important to consider the methodological flaws of most SRs.

Captopril oral solution for pediatric use: formulation, stability study and palatability assessment in vivo

Abstract he aim of this work was to develop an oral solution of captopril at 5 mg/mL preservative-free. Two formulations were prepared, one containing sweetener (formulation 1) and the other without this excipient (formulation 2). The results found of validation parameters from analytical method performed by HPLC for captopril were, linearity 0.9998, the limit of detection 15.71 µg/mL, the limit of quantification 47.60 µg/mL, repeatability 1.05%, intermediate precision 2.42%, accuracy intraday 101,53%, accuracy inter-day 99.85%. Moreover, the results found for captopril disulfide were, linearity 0.9999, limit of detection 0.65 µg/mL, limit of quantification 1.96 µg/mL, repeatability 2.28%, intermediate precision 1.51%, accuracy intraday 101.36%, accuracy inter-day 100.29%. The appearance of formulations was clear and colorless, pH measures were 3.12 and 3.04, dosage of captopril and captopril disulfide were 99.45% and 99.82%, 0.24% and 0.12% for formulation 1 and formulation 2, respectively. The stability study demonstrated that the concentration of captopril and captopril disulfide in the formulations was > 90% and below 3%, respectively. The in vivo palatability study in animals and humans showed that Formulation 1 containing the sweetener had better acceptance. Thus, the sweetener was able to improve the unpleasant taste of the formulation

Why the "sugars" in traditional Unani formulations are a pivotal component: A viewpoint perspective / 中西医结合学报

Traditional medicine systems around the globe, like Unani, Ayurveda and traditional Chinese medicine, include a number of sugar-based formulations, which contain a large amount of saccharide-containing sweetener, such as honey, sucrose or jaggery. With pervasive lifestyle disorders throughout the world, there have been discussions to consider alternative sweetening agents. Here, from the perspective of Unani medicine, we discuss how the saccharide-based sweeteners may be an essential component of these traditional preparations, like electuaries, which may be deprived of their bioactivities without these saccharides. With contemporary researches, it is known that apart from their own therapeutic effects, saccharides also form deep eutectic solvents which help in enhancing the bioactivity of other ingredients present in crude drugs. In addition, they provide energy for fermentation which is essential for biotransformation of compounds. Interestingly, the sugars also increase the shelf-life of these compound drugs and act as natural preservatives. On the basis of this review, we strongly believe that saccharide-based sweeteners are an essential component of traditional medicines and not merely an excipient.

Consumo crónico de edulcorantes en ratones y su efecto sobre el sistema inmunitario y la microbiota del intestino delgado / Chronic consumption of sweeteners in mice and its effect on the immune system and the small intestine microbiota

Resumen Introducción. Los edulcorantes son aditivos que se consumen en los alimentos. Pueden ser naturales (sacarosa y estevia) o artificiales (sucralosa). Actualmente, se consumen rutinariamente en múltiples productos, y sus efectos en la mucosa y la microbiota del intestino delgado aún son controversiales. Objetivo. Relacionar el consumo de edulcorantes y su efecto en el sistema inmunitario y la microbiota del intestino delgado en ratones CD1. Materiales y métodos. Se utilizaron 54 ratones CD1 de tres semanas de edad divididos en tres grupos: un grupo de tres semanas sin tratamiento, un grupo tratado durante seis semanas y un grupo tratado durante 12 semanas. Se les administró sacarosa, sucralosa y estevia. A partir del intestino delgado, se obtuvieron linfocitos B CD19+ y células IgA+, TGF-ß (Transforming Growth Factor-beta) o el factor de crecimiento transformador beta (TGF-beta), IL-12 e IL-17 de las placas de Peyer y de la lámina propia. De los sólidos intestinales se obtuvo el ADN para identificar las especies bacterianas. Resultados. Después del consumo de sacarosa y sucralosa durante 12 semanas, se redujeron las comunidades bacterianas, la IgA+ y el TGF-beta, se aumentó el CD19+, y además, se incrementaron la IL-12 y la IL-17 en las placas de Peyer; en la lámina propia, aumentaron todos estos valores. En cambio, con la estevia mejoraron la diversidad bacteriana y el porcentaje de linfocitos CD19+, y hubo poco incremento de IgA+, TGF-ß e IL-17, pero con disminución de la IL-17. Conclusión. La sacarosa y la sucralosa alteraron negativamente la diversidad bacteriana y los parámetros inmunitarios después de 12 semanas, en contraste con la estevia que resultó benéfica para la mucosa intestinal.

Abstract Introduction: Sweeteners are additives used in different foods. They can be natural (sucrose and stevia) or artificial (sucralose). Currently, they are routinely consumed in multiple products and their effects on the mucosa of the small intestine and its microbiota are still controversial. Objective: To relate the consumption of sweeteners and their effect on the immune system and the microbiota of the small intestine in CD1 mice. Materials and methods: We used 54 three-week-old CD1 mice divided into three groups in the experiments: 1) A group of three weeks without treatment, 2) a group treated for six weeks, and 3) a group treated for 12 weeks using sucrose, sucralose, and stevia. We obtained CD19+ B lymphocytes, IgA+ antibodies, transforming growth factor-beta (TGF-b), and interleukins 12 and 17 (IL-12 and -17) from Peyer's patches and lamina propria cells while DNA was obtained from intestinal solids to identify bacterial species. Results: After 12 weeks, sucrose and sucralose consumption caused a reduction in bacterial communities with an increase in CD19+, a decrease in IgA+ and TGF-b, and an increase in IL-12 and -17 in the Peyer's patches while in the lamina propria there was an increase in all parameters. In contrast, stevia led to an improvement in bacterial diversity and percentage of CD19+ lymphocytes with minimal increase in IgA+, TGF-b, and IL-12, and a decrease in IL-17. Conclusion: Sucrose and sucralose caused negative alterations in bacterial diversity and immune parameters after 12 weeks; in contrast, stevia was beneficial for the intestinal mucosa.

Excise taxes on sugar-sweetened beverages in Latin America and the Caribbean / Impuestos selectivos al consumo de bebidas azucaradas en América Latina y el Caribe / Imposto especial de consumo sobre bebidas açucaradas na América Latina e no Caribe

ABSTRACT Objective. To characterize the design of excise taxes on sugar-sweetened beverages (SSBs) in Latin America and the Caribbean and assess opportunities to increase their impact on SSB consumption and health. Methods. A comprehensive search and review of the legislation in effect as of March 2019, collected through existing Pan American Health Organization and World Health Organization monitoring tools, secondary sources, and surveying ministries of finance. The analysis focused on the type of products taxed, and the structure and base of these excise taxes. Results. Out of the 33 countries analyzed, 21 apply excise taxes on SSBs. Seven countries also apply excise taxes on bottled water and at least four include sugar-sweetened milk drinks. Ten of these excise taxes are ad valorem with some tax bases set early in the value chain, seven are amount-specific, and four have either a combined or mixed structure. Three countries apply excise taxes based on sugar concentration. Conclusions. While the number of countries applying excise taxes on SSBs is promising, there is great heterogeneity in design in terms of structure, tax base, and products taxed. Existing excise taxes could be further leveraged to improve their impact on SSB consumption and health by including all categories of SSBs, excluding bottled water, and relying more on amount-specific taxes regularly adjusted for inflation and possibly based on sugar concentration. All countries would benefit from additional guidance. Future research should aim to address this gap.

RESUMEN Objetivo. Caracterizar el diseño de los impuestos selectivos al consumo de bebidas azucaradas en América Latina y el Caribe, y evaluar las oportunidades de aumentar su impacto en el consumo y la salud. Métodos. Se llevó a cabo una búsqueda y una evaluación exhaustivas de legislaciones vigentes a marzo del 2019, recopilada mediante las herramientas de seguimiento ya existentes de la Organización Panamericana de la Salud y de la Organización Mundial de la Salud, fuentes secundarias, así como mediante una encuesta a ministerios de finanzas. El análisis se centró en el tipo de productos gravados y la estructura y la base de estos impuestos selectivos. Resultados. De los 33 países evaluados, en 21 se aplican impuestos selectivos al consumo de bebidas azucaradas. En siete países también se aplican impuestos selectivos al consumo de agua embotellada y en al menos cuatro, se incluyen las bebidas lácteas azucaradas. Diez de estos impuestos selectivos al consumo son de tipo ad valorem con algunas bases imponibles fijadas al principio de la cadena de valor, siete son de tipo específico y cuatro son de estructura combinada o mixta. En tres países se aplican impuestos selectivos al consumo en función de la concentración de azúcares del producto. Conclusiones. Si bien el número de países en que se aplican impuestos selectivos al consumo de bebidas azucaradas es prometedor, existe una gran heterogeneidad en su diseño en cuanto a la estructura, la base imponible y los productos gravados. Se podrían aprovechar aún más los impuestos selectivos existentes a fin de que tengan un mayor impacto sobre la salud y el consumo si se incluyen todas las categorías de bebidas azucaradas, excluyendo el agua embotellada, y recurriendo más a impuestos de tipo específico ajustados frecuentemente según la inflación y basados posiblemente en la concentración de azúcares del producto. Todos los países se beneficiarían si hubiera mayor orientación. Las próximas investigaciones deberían abordar esta brecha.

RESUMO Objetivo. Caracterizar o modelo dos impostos especiais de consumo sobre bebidas açucaradas na América Latina e no Caribe e avaliar oportunidades para aumentar o impacto desses impostos no consumo de bebidas açucaradas e na saúde. Métodos. Realizou-se uma pesquisa ampla e a análise de legislações vigentes em março de 2019, com informações obtidas por meio de instrumentos de monitoramento da Organização Pan-Americana da Saúde (OPAS) e da Organização Mundial da Saúde (OMS) já existentes, fontes secundárias e levantamento junto aos ministérios da Fazenda. A análise centrou-se no tipo de produtos tributados e na estrutura e base desses impostos especiais de consumo. Resultados. Dos 33 países analisados, 21 aplicam impostos especiais de consumo sobre bebidas açucaradas. Em sete países os impostos especiais de consumo incidem também sobre água engarrafada e, em pelo menos quatro, incluem bebidas lácteas açucaradas. Dez desses tributos especiais são ad valorem com algumas bases tributárias estabelecidas no início da cadeia de valor, sete são de tipo específico e quatro têm uma estrutura combinada ou mista. Em três países os impostos especiais são estabelecidos com base na concentração de açúcares do produto. Conclusões. Apesar do número promissor de países com impostos especiais de consumo sobre bebidas açucaradas, verifica-se grande heterogeneidade nos modelos de tributação em termos de estrutura, base tributária e produtos tributados. Os impostos especiais de consumo vigentes poderiam ser mais bem aproveitados para aumentar o impacto no consumo de bebidas açucaradas e na saúde: incluir todas as categorias de bebidas açucaradas, excluir água engarrafada e recorrer mais a impostos de tipo específico com a correção periódica pela inflação e, possivelmente, com base na concentração de açúcares do produto. Todos os países se beneficiariam em receber mais orientação. Pesquisas futuras devem ter como objetivo abordar essa lacuna.

Impacto del uso de edulcorantes no calóricos en la salud cardiometabólica / Impact of the use of calorie-free sweeteners on cardiometabolic health

Resumen Los edulcorantes son sustancias capaces de sustituir el dulzor característico del azúcar y en la actualidad son muy utilizados por su capacidad edulcorante, superior a la de la sacarosa, lo que hace que se requieran menos cantidades de estos en los alimentos. Esta característica ha despertado el interés de muchos investigadores por sus posibles beneficios para pacientes con diabetes y obesidad, entre otras morbilidades. En este artículo se hace una revisión acerca de la relación de los edulcorantes no calóricos con el control del peso, el síndrome metabólico y la aparición de eventos cardiovasculares.

Abstract Sweeteners are substances capable of replacing the characteristic sweetness of sugar. They are currently widely used for their sweetener capacity, which is greater than that of saccharose, and which means lower quantities are required in foods. This characteristic has aroused the interest of many researchers due to their possible benefits in diabetes and obesity, as well as in other disorders. A review is presented in this article on the relationship between calorie-free sweeteners and weight control, metabolic syndrome, and the appearance of cardiovascular events.

Effects of oral isotretinoin therapy on the nasal cavities / Efeitos nasais da terapia com isotretinoína oral

Abstract Introduction Isotretinoin (13 cis-retinoic acid) is the most effective treatment for acne vulgaris and is the only treatment option that can provide either remission or a permanent cure. Objective The aim of this study was to use both subjective and objective methods to assess the nasal complaints of patients with severe acne who received oral isotretinoin therapy. Methods Fifty-four subjects were enrolled in the study. All the subjects were assessed with subjective (NOSE and VAS questionnaires) and objective (rhinomanometry and saccharine) tests to determine the severity of their nasal complaints. Results The mean severity scores (min: 0; max: 100) for nasal dryness/crusting and epistaxis were 0.47 ± 1.48 (0-5); 0.35 ± 1.30 (0-5) at admission, 3.57 ± 4.45 (0-10); 2.26 ± 4.71 (0-20) at the first month, and 4.28 ± 6 (0-20); 2.26 ± 4.71 (0-20) at the third month of the treatment respectively. Total nasal resistance of 0.195 ± 0.079 (0.12-0.56) Pa/cm3/s at admission, 0.21 ± 0.084 (0.12-0.54) Pa/cm3/s at the first month, and 0.216 ± 0.081 (0.14-0.54) Pa/cm3/s at the third month. Conclusion Oral isotretinoin therapy can cause the complaint of nasal obstruction. In addition, nasal complaints, such as dryness/crusting and epistaxis, significantly increase in patients during the therapy schedule.

Derecho al consumo informado: el caso de las bebidas azucaradas en Colombia / Right to informed consumption: the case of sugar-sweetened beverages in Colombia

Introducción: se presenta un análisis sobre el derecho al consumo informado en el caso de las bebidas azucaradas, a través del recorrido administrativo y judicial en Colombia. Metodología: se hace desde una perspectiva jurídica, bioética y médica, señalando cómo la protección judicial de este derecho se da gracias al activísimo social y judicial que se enfrenta con el lobby de la industria, cuyos intereses también inciden, no en el ámbito del acceso a la justicia, pero si en el del diseño de políticas públicas en salud para reducir el consumo de bebidas azucaradas. Conclusiones: de la revisión de la literatura se encontró que ciertas enfermedades no transmisibles se asocian con el consumo de estos productos, por lo cual en diferentes regiones del mundo se han replanteado medidas para mitigar su impacto, mientras en Colombia el escenario desde las políticas públicas no ha sido favorable.

Introduction: an analysis of the right to informed sugar-sweetened beverages consumption is herein presented from the administrative and legal background in Colombia. Methodology: a study conducted from the legal, bioethical and medical perspective, pointing out how legal protection of this right is possible thanks to social and legal activism which faces industrial lobby whose interests do not influence the access to justice institutions but does influence the design of health public policy for reducing sugar-sweetened beverages intake. Conclusions: our review of the literature found that certain non-communicable diseases are associated with the intake of these products for which measures to mitigate their impact have been reconsidered in different regions of the world, while in Colombia the public policy scenario has been unfavorable.

Synthetic biology for the synthesis of mogroside V - a review / 生物工程学报

Mogroside V, a component with high content and sweetness in mogrosides, has many pharmacological activities such as relieving cough, reducing sputum, anti-cancer, anti-oxidation, regulating blood sugar, making it a natural nonsugar sweetener with therapeutic functions, and showing a broad market prospect. However, the limited resources and high extraction costs have restricted its widespread use. The rapid development of synthetic biology has provided a new idea for the production of plant natural products. The low-cost and large-scale production will be realized through the construction of a microbial cell factory for mogroside V. Here, we briefly introduce the structure and pharmacological activity of mogroside V, and review progress in applying synthetic biology for its synthesis, and also discuss the challenges faced by the current research, to provide a reference for further studies on the biosynthesis of mogroside V.

Consumo de açúcares de adição por adolescentes em estudo de base populacional / Added sugar intake by adolescents: A population-based study

Resumo Objetivou-se estimar a prevalência de ingestão de açúcares de adição dentro do limite máximo de 5% da energia total da dieta, segundo variáveis demográficas, socioeconômicas, de comportamentos relacionados à saúde e estado nutricional, em adolescentes. Trata-se de estudo transversal de base populacional, com amostra por conglomerados e em dois estágios. A quantidade de açúcar livre da dieta foi estimada por meio do Recordatório de 24 horas. Dos 924 adolescentes avaliados, apenas 20,1% (IC95%: 16,8-23,9) se enquadraram na recomendação de não exceder 5% das calorias totais com açúcares de adição. Maiores prevalências de atendimento à recomendação foram verificadas no sexo masculino (22,0%), nos adolescentes de 15-19 anos (24,3%), nos não naturais do estado de São Paulo (30,4%), nos que tinham menor tempo de tela (27,5%), nos que possuíam menor número de equipamentos domésticos (0-7: 29,5%; 8-15: 20,3%) e naqueles com escores superiores de qualidade da dieta (tercil 2: 17,7%, tercil 3: 37,2%). Os resultados apontam os fatores associados ao consumo de açúcares de adição numa perspectiva epidemiológica, revelando uma simultaneidade de comportamentos inadequados, ou seja, os adolescentes que ingerem mais açúcares também apresentam maior tempo de tela e pior qualidade global da dieta.

Abstract The aim of the present study was to estimate the prevalence of added sugar intake within the maximum limit of 5% of the total energy of the diet and test associations with demographic/socioeconomic characteristics, health-related behaviors and nutritional status in adolescents. A population-based, cross-sectional study was conducted with two-stage cluster sampling. The amount of free sugar in the diet was estimated using a 24-hour dietary recall. Among the 924 adolescents evaluated, only 20.1% (95% CI: 16.8-23.9) met the recommendation of not exceeding 5% of total calories with added sugar. Higher prevalence rates of adherence to the recommendation were found among males (22.0%), adolescents aged 15 to 19 years (24.3%), those born outside the state of São Paulo (30.4%), those with less screen time (27.5%), those with a lower number of household appliances (0-7: 29.5%; 8-15: 20.3%) and those with higher diet quality scores (2nd tertile: 17.7%; 3rd tertile: 37.2%). The findings demonstrate factors associated with added sugar intake from an epidemiological perspective, revealing the simultaneity of inappropriate behaviors, that is, the adolescents who consume more sugar also have longer screen time and worse overall diet quality.

Efectos metabólicos del consumo excesivo de fructosa añadida / Metabolic effects of excessive fructose consumption added

El consumo de fructosa ha aumentado en los últimos 50 años por la incorporación a la dieta de jarabe de maíz alto en fructosa (JMAF), presente en productos industrializados, como las bebidas azucaradas. Se puede asociar la ingesta de fructosa en altas concentraciones con el aumento de la obesidad y trastornos metabólicos. La fructosa, un azúcar natural que se encuentra en muchas frutas, se consume en cantidades significativas en las dietas occidentales. En cantidades iguales, es más dulce que la glucosa o la sacarosa y, por lo tanto, se usa comúnmente como edulcorante. Debido al incremento de obesidad entre la población joven y general y a los efectos negativos que puede tener a corto y largo plazo es importante considerar de donde provienen las calorías que se ingieren diariamente. Esta revisión describirá la relación entre el consumo de fructosa en altas concentraciones y el riesgo de desarrollar obesidad, resistencia a la insulina, lipogenesis de novo e inflamación.

The consumption of fructose has increased in the last 50 years due to the incorporation into the diet of high fructose corn syrup (HFCS), present in industrialized products, such as sugary drinks. The intake of fructose in high concentrations can be associated with the increase of obesity and metabolic disorders. Fructose, a natural sugar found in many fruits, is consumed in significant quantities in Western diets. In equal amounts, it is sweeter than glucose or sucrose and, therefore, is commonly used as a sweetener. Due to the increase of obesity among the young and general population and the negative effects that can have in the short and long term it is important to consider where the calories that are ingested daily come from. This review will describe the relationship between fructose consumption in high concentrations and the risk of developing obesity, insulin resistance, de novo lipogenesis, nonalcoholic fatty liver, inflammation and metabolic syndrome.

Postprandial metabolic effects of fructose and glucose in type 1 diabetes patients: a pilot randomized crossover clinical trial

ABSTRACT Objective To test the influence of oral fructose and glucose dose-response solutions in blood glucose (BG), glucagon, triglycerides, uricaemia, and malondialdehyde in postprandial states in type 1 diabetes mellitus (T1DM) patients. Subjects and methods The study had a simple-blind, randomized, two-way crossover design in which T1DM patients were selected to receive fructose and glucose solutions (75g of sugars dissolved in 200 mL of mineral-water) in two separate study days, with 2-7 weeks washout period. In each day, blood samples were drawn after 8h fasting and at 180 min postprandial to obtain glucose, glucagon, triglycerides, uric acid, lactate, and malondialdehyde levels. Results Sixteen T1DM patients (seven men) were evaluated, with a mean age of 25.19 ± 8.8 years, a mean duration of disease of 14.88 ± 4.73 years, and glycated hemoglobin of 8.13 ± 1.84%. Fructose resulted in lower postprandial BG levels than glucose (4.4 ± 5.5 mmol/L; and 12.9 ± 4.1 mmol/L, respectively; p < 0.01). Uric acid levels increased after fructose (26.1 ± 49.9 µmol/L; p < 0.01) and reduced after glucose (-13.6 ± 9.5 µmol/L; p < 0.01). The malondialdehyde increased after fructose (1.4 ± 1.6 µmol/L; p < 0.01) and did not change after glucose solution (-0.2 ± 1.6 µmol/L; p = 0.40). Other variables did not change. Conclusions Fructose and glucose had similar sweetness, flavor and aftertaste characteristics and did not change triglycerides, lactate or glucagon levels. Although fructose resulted in lower postprandial BG than glucose, it increased uric acid and malondialdehyde levels in T1DM patients. Therefore it should be used with caution.

Análise de tempo-intensidade e aceitação de refrigerantes / Time-intensity analysis and acceptance of soda

Refrigerantes diet e light podem possuir sabor residual em função do uso de edulcorantes. Entender como esta característica afeta a qualidade sensorial é essencial para indústria. Cinco marcas de refrigerante foram avaliadas quanto às características sensoriais. A análise de Tempo-Intensidade foi realizada com provadores treinados e a aceitação com 80 consumidores de refrigerante. Os dados foram submetidos à análise de variância e teste de comparação entre medias. Para o gosto doce e residual de adoçante não houve diferença significativa entre as amostras. A amostra D diferiu-se das demais com maior intensidade para o gosto ácido. As amostras A e E foram as mais aceitas pelos consumidores. O uso de diferentes combinações de edulcorantes leva a diferentes percepções sensoriais, sendo fundamental este estudo nos produtos light e diet.
