White and Brown Crystal Sugar dietary: a high consumption effect in D. Melanogater

The high consumption of sugars in their different forms has been of concern to the International Health organization (WHO). In this study, D. melanogater (born in the dietary medium - Generation F1) male and females were submitted to a white (WS) and brown (BS) Cristal Sugars rich diet. Results obtained indicate an increase in oxidative stress with an increase in the consumption of sugar in the diet, as observed in the increase in the enzymatic activity of SOD, CAT and GPx. These results are corroborated by analyzes of lipid peroxidation (TBARS), carbonyl content and ROS (DCFH), which clearly demonstrate an increase in the formation of reactive oxygen species with the increase in the consumption of sugars both white and brown crystal sugars. Another effect observed by the increase in sugar consumption was the augmentation in glucose levels (white and brown sugars) and in iron levels (brown sugar). In this sense, the high consumption of iron in brown sugar has contributed more strongly to the formation of ROS in D. melanogaster, mainly in females.
