Changes in Antioxidant Enzymes in Metabolic Syndrome Patients after Consumption a Citrus-Based Juice Enriched with Aronia Melanocarpa

Increased oxidative stress has been suggested as an early event in the development of the metabolic syndrome and, as such, might contribute to disease progression. The aim of de present study was to evaluate Total Antioxidant Status and endogenous antioxidant enzymes in metabolic syndrome patients after consumption of a citrus-based juice compared with control groups. Before, and at sixth month after treatment the following parameters were determined: Total Antioxidant Status, Superoxide Dismutase, Glutathione Peroxidase and Glutathione Reductases. After six months of citrus-based juice consuming, there was no significant differences at 95% confidence in Total Antioxidant Status between three groups, although it was found significant differences between groups in values of three antioxidant enzymes analysed. As a conclusion, the intake of a citrus-based juice increases the levels of antioxidant enzymes, despite do not increase the Total Antioxidant Status after its intake during 6 months.
