Abstract(s)
Objetivo: Avaliar o impacto do consumo de Kombucha nos níveis de glicemia pós-prandial em adultos não diabéticos.
Metodologia: Este estudo teve a participação de 22 adultos saudáveis, com idades entre os 20 e 60 anos. O estudo foi conduzido em dois dias distintos, separados por uma semana. No primeiro dia, após 12 horas de jejum, os participantes assinaram o consentimento informado, preencheram um inquérito geral e um inquérito alimentar e foram feitas avaliações antropométricas. De seguida, mediu-se a glicemia em jejum após o que os participantes consumiram uma refeição rica em hidratos de carbono. Imediatamente a seguir, procedeu-se à medição da glicemia pós-prandial aos 30, 60, 90 e 120 minutos após a refeição. No segundo dia, o procedimento foi idêntico, porém os participantes ingeriram 240 mL de Kombucha logo após a ingestão da refeição. Foi utilizado o teste t-student para amostras pareadas para verificar os níveis de glicemia pós-prandial em diferentes moimentos e o teste t-student para amostras independentes para diferenciar entre os diferentes grupos (idade e sexo).
Resultados: Não foram observadas diferenças significativas nos parâmetros antropométricos entre os dias de intervenção. A glicemia em jejum foi semelhante nos dois dias, sem alterações significativas (p > 0,05). O consumo de Kombucha reduziu significativamente a glicemia pós-prandial aos 30 minutos (p=0,006), a variação máxima da glicemia (p=0,031) e a área abaixo da curva glicémica (p=0,009). Os homens apresentaram maior redução na glicemia pós-prandial em comparação às mulheres, especialmente na faixa etária mais jovem (20-35 anos). Não houve diferenças significativas nas respostas glicémicas entre as faixas etárias no grupo feminino.
Conclusões: O consumo de Kombucha demonstrou um efeito positivo no controle da glicemia pós-prandial em adultos não diabéticos, com maior impacto observado entre os homens mais jovens. Esses resultados sugerem o potencial da Kombucha como adjuvante na regulação da glicemia. No entanto, realça-se a necessidade de realizar estudos adicionais com amostras maiores para validar estes resultados e explorar melhor o potencial da Kombucha como ferramenta de intervenção nutricional para o controlo do metabolismo da glicose.
Objective: To assess the impact of Kombucha consumption on postprandial blood glucose levels in non-diabetic adults. Methodology: This study involved 22 healthy adults aged between 20 and 60. The study was conducted on two separate days, one week apart. On the first day, after 12 hours of fasting, the participants signed an informed consent form, completed a general survey and a dietary survey, and anthropometric assessments were made. Next, fasting blood glucose was measured, after which the participants consumed a carbohydrate-rich meal. Immediately afterwards, postprandial blood glucose was measured at 30, 60, 90 and 120 minutes after the meal. On the second day, the procedure was identical, but the participants drank 240 mL of Kombucha immediately after eating the meal. The student’s t-test for paired samples was used to check postprandial blood glucose levels at different times and the student’s t-test for independent samples was used to differentiate between the different groups (age and gender). Results: No significant differences were observed in anthropometric parameters between the intervention days. Fasting blood glucose was similar on both days, with no significant changes (p > 0.05). Kombucha consumption significantly reduced postprandial blood glucose at 30 minutes (p=0.006), maximum blood glucose variation (p=0.031) and the area under the glucose curve (p=0.009). Men showed a greater reduction in postprandial glycemia compared to women, especially in the younger age group (20-35 years). There were no significant differences in glycemic responses between age groups in the female group. Conclusions: Kombucha consumption showed a positive effect on postprandial blood glucose control in non-diabetic adults, with a greater impact observed among younger men. These results suggest the potential of Kombucha as an adjuvant in regulating glycemia. However, there is a need for further studies with larger samples to validate these results and better explore the potential of Kombucha as a nutritional intervention tool for controlling glucose metabolism.
