Abstract High postprandial glycemia in the non-diabetic population is one of the known universal mechanisms for the progression of noncommunicable diseases (NCDs), which have impacted the finances of both individuals and of health systems. In order to highlight the role of carbohydrates in glycemic control and its implications on health, the International Life Sciences Institute Brazil held an international workshop on “Carbohydrates, Glycemia and Health”. Carbohydrate digestion rate is related to glycemic response, which mainly depends on the quality and amount of carbohydrate ingested, and thus it may be modulated by intrinsic and extrinsic factors. These effects can be verified by using different methods which evidence how physiology adapts in the uptake of glucose. Consumers can be aided with the knowledge/awareness of the benefits of high postprandial glycemia control in non-diabetic subjects. Multisectorial actions can contribute to decrease the onset and worsening of NCDs. A strategy indicated to the public in general to expand the availability of products that do not result in a sudden increase of postprandial plasma glucose and/or insulin would be to use alternative ingredients and/or technology in addition to making the legally allowed communication of benefits, which are supported by scientific studies.

RESUMO Contexto - O funcionamento intestinal é um dos parâmetros amplamente avaliado em estudos intervencionais e longitudinais, pois está associado à manutenção da saúde. A avaliação do funcionamento intestinal tem sido realizada por diferentes questionários, mas são poucas as alternativas validadas em português. Objetivo - O objetivo deste trabalho foi traduzir e validar para a língua portuguesa (Brasil) o questionário Gastrointestinal Symptom Rating Scale (GSRS). Métodos - A tradução e adaptação cultural foram realizadas de acordo com metodologia previamente estabelecida, seguida dos cálculos de confiabilidade. Resultados - A aplicação do questionário GSRS traduzido apresentou valor de confiabilidade geral alfa de Cronbach de 0,83, classificado como adequado, e seus domínios foram classificados de aceitável a adequado; o teste-reteste geral apresentou coeficiente de correlação intraclasse de 0,84, considerado excelente. Conclusão - O GSRS foi traduzido e validado para Português (Brasil), apresentando confiabilidade e reprodutibilidade apropriadas, e está disponível para ser utilizado em avaliações de funcionamento intestinal.

ABSTRACT Background - Bowel function is a widely evaluated parameter in interventional and longitudinal studies since it is associated with good maintenance of health. The evaluation of intestinal function has been performed by many questionnaires, however, there are few options validated in Brazilian Portuguese. Objective - The aim of this work was to translate and validate into Brazilian Portuguese the Gastrointestinal Symptom Rating Scale (GSRS) questionnaire. Methods - Translation and cultural adaptation were performed according to a previously established methodology followed by reliability calculations. Results - The final translated GSRS questionnaire showed an adequate value of overall reliability of Cronbach's alpha of 0.83, and its domains were classified from acceptable to adequate. The overall test-retest reliability by intraclass correlation coefficient (ICC) was 0.84, considered excellent. Conclusion - The GSRS was translated and validated into Brazilian Portuguese, with appropriate internal consistency and reliability and is available to be used in assessments of bowel function.

O Brasil é o terceiro maior produtor de abacaxi(Ananas comosus) e as principais cultivares encontradas no mercado são Havaí e Pérola. Neste trabalho, frutas da cultivar Pérola foram divididas em casca, cerne e polpa e analisadas. A umidade da polpa foi superior (entre 10 e 15%) à encontrada na casca e no cerne. A concentração de proteína foi maior no cerne (35%) que na polpa e na casca. Essa cultivar contém baixas concentrações de ácido ascórbico nas partes comestíveis, no entanto a casca apresentou maiores níveis. O ácido cítrico correspondeu a aproximadamente 60% do total de ácidos orgânicos. Entre os açúcares solúveis [~7-12% (BU)], a sacarose, frutose e glicose foram predominantes. O cerne continha quase o dobro dos açúcares totais (12%) em relação à polpa (6,8%). A concentração de fibra alimentar insolúvel foi em torno de 1%, enquanto a de fibra solúvel foi menor que 0,1%. A polpa apresentou maior concentração de polifenóis (0,49%) e maior atividade antioxidante (33 µmol.g-1) que as demais partes. O consumo da polpa e do cerne produziu alto índice glicêmico (~93%), mas considerando a quantidade usual consumida, o abacaxi apresenta baixa carga glicêmica.

Brazil is the third largest producer of pineapple (Ananas comosus) and the market for fresh pineapple is sustained by the Hawaii and Perola cultivars. In this work the Perola cultivar was divided into three main parts, shell, core and pulp, for characterization. Moisture in the pulp was higher (between 10 and 15%) than in the shell and core. The amount of protein was higher in the core (35%) than in the pulp and shell. Perola contained relatively low concentrations of total ascorbic acid in the edible parts, although higher levels of ascorbic acid in the shell. Citric acid corresponded to almost 60% of the total organic acids. The total soluble sugars [~7-12% (FW)] were predominantly sucrose, fructose and glucose. The core had almost twice as much total sugar (12%) than the pulp (6.8%). The amount of insoluble dietary fiber was around 1%, and the soluble fiber was less than 0.1%. The pulp showed the highest concentration of polyphenols (0.49%) and antioxidant activity (33 µmol.g-1) out of the parts. The consumption of the pineapple pulp or core produced a high glycemic index (~93%), but considering the glycemic load, this fruit can be considered as low dietary.
