Caramel dye IV (C-IV) is a synthetic organic product, does not present nutritional, ergogenic, or technological factors, but leads to reactive oxygen species (ROS). This way may lead to damage to a wide range of molecules, leading to cancer, cardiovascular, and neurodegenerative diseases development. We aimed to verify the effects of different doses of C-IV dye on the markers of oxidative stress in the liver and kidneys from male Swiss CF-1 mice, divided into four experimental groups: control; C-IV 0.3 g/kg; C-IV 1 g/kg and C-IV 3 g/kg. We found that mainly 3 g/Kg of C-IV dye promote oxidative damage in liver and kidney homogenates, evidenced by the increase of lipid peroxidation, reduction of free SH groups, and higher ROS production. As a consequence, increased superoxide dismutase, catalase, and acetylcholinesterase enzyme activities were detected, as a response to the increased oxidative stress production. These damages were confirmed through histology images. Since the mice dose used in this study is 30-fold lower than the human daily dose consumption, these results indicate that the daily doses might induce substantial oxidative stress damages and possibly lead to chronic disease development.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
