Abstract(s)
Objetivo: Estudar o efeito do chá Fitos 8 nos níveis de glicemia pós-prandial, em adultos não diabéticos.
Metodologia: Realizou-se um ensaio clínico com 22 participantes, em dois dias, com um período de washout de sete dias. Os participantes jejuaram, pelo menos, 8 horas antes de cada dia de ensaio. No primeiro dia, foi assinado pelos participantes o consentimento informado, preenchidos os inquéritos geral e alimentar e foram recolhidos dados antropométricos. Posteriormente, foi medida a glicemia pré-prandial, seguida da ingestão de uma refeição padrão e, por fim, foi medida a glicemia pós-prandial aos 30, 60, 90 e 120 minutos. No segundo dia, repetiu-se o protocolo, mas após a ingestão da refeição padrão, os participantes ingeriram 240 mL de chá Fitos 8. De seguida fizeram-se as medições da glicemia pós-prandial aos mesmos intervalos.
Resultados: Verificou-se uma redução significativa nos níveis de glicose pós-prandial aos 30 e 120 minutos (p=0,036 e p<0,001, respetivamente) após a ingestão de chá Fitos 8. Houve também uma diminuição significativa dos valores médios da área abaixo da curva (p=0,002) e da concentração máxima (p=0,010). No entanto, a variação da concentração máxima não foi estatisticamente significativa (p=0,196). Foi ainda verificado que o sexo feminino e a faixa etária dos 36 aos 56 anos foram o grupo que mais beneficiaram com a ingestão do chá Fitos 8.
Conclusão: Os resultados revelaram um possível efeito benéfico da ingestão de chá Fitos 8 no controlo glicémico.
Aim: To study the effect of Fitos 8 tea on postprandial glycaemia levels in non-diabetic adults. Methodology: A clinical trial was conducted with 22 participants over two days, with a washout period of seven days. The participants fasted for at least 8 hours prior to each day of the trial. On the first day, participants signed the informed consent form, completed general and dietary questionnaires, and underwent anthropometric measurements. Subsequently, pre-prandial blood glucose was measured, followed by the consumption of a standard meal, and finally, postprandial blood glucose was measured at 30, 60, 90, and 120 minutes. On the second day, the protocol was repeated, but after consuming the standard meal, the participants consumed 240 mL of Fitos 8 tea. Following this, postprandial blood glucose measurements were taken at the same intervals. Results: A significant reduction in postprandial glucose levels was observed at 30 and 120 minutes (p=0,036 and p<0,001, respectively) following the consumption of Fitos 8 tea. There was also a significant decrease in the mean values of the area under the curve (AUC) (p=0,002) and the maximum concentration (p=0,010). However, the variation in maximum concentration was not statistically significant (p=0,196). It was also noted that females and participants aged 36 to 56 years benefited the most from the consumption of Fitos 8 tea. Conclusion: The results indicated a potential beneficial effect of Fitos 8 tea consumption on glycaemic control.
