ABSTRACT

Abstract The relation between oxidative stress and inflammation induced by diseases and exercise has increased the interest in the benefits of antioxidant supplements in the improvement of health and physical and mental performance. The aim of this study was to evaluate the effectiveness of açai gel in reducing oxidative stress in individuals engaged in physical activities as well as their acceptance. Sensory evaluation was performed to determine its acceptability and the biochemical parameters related to immune profile and biomarkers of muscle, liver and oxidative stress, with and without the use of gel were evaluated. The appearance, sweetness and overall impression of the açai gel were considered good. It was observed a significant increase in CK enzyme, without the gel as well as the oxidative stress biomarkers, it was observed that the MDA (with and without gel) a significant increase (p < 0.05). Through biochemical evaluation, it is concluded that the gel provided protection for some of parameters studied, since it modulated the immunological parameter reducing the lymphocyte activity and muscular stress. However, more studies must be carried out with a larger number of individuals to confirm the gel functionality.

ABSTRACT

A dieta influencia todos os estágios do ciclo da vida, fornecendo nutrientes necessários ao sustento do corpo humano. Alterações de ordem funcional e/ou estrutural, provocadas por doenças e infecções agudas ou crônicas, levam à utilizaçäo de medicamentos, cujo o objetivo é restaurar a saúde. A via preferencial escolhida para a sua administraçäo é a oral, entre outras razões, por sua comodidade e segurança. O fenômeno de interaçäo fármaco-nutriente pode surgir antes ou durante a absorçäo gastrintestinal, durante a distribuiçäo e armazenamento nos tecidos, no processo de biotransformaçäo ou mesmo durante a excreçäo. Assim, é de importância fundamental conhecer os fármacos cuja velocidade de absorçäo e/ou quantidade absorvida podem ser afetadas na presença de alimentos, bem como aqueles que näo säo afetados. Por outro lado, muitos deles, incluindo antibióticos, antiácidos e laxativos podem causar má absorçäo de nutrientes. Portanto o objetivo do presente artigo é apresentar uma revisäo dos diversos aspectos envolvidos na interaçäo fármaco-nutriente
