A Preliminary Study Investigating the Effects of Elevated Antioxidant Capacity of Daily Snacks on the Body’s Antioxidant Defences in Patients with CVD

The antioxidant potential of foods plays a vital role in counteracting oxidative stress and its consequences the body. Superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) are primary line defence against cellular damage caused by reactive oxygen species (ROS). Glutathione is considered to be most for body because changes during increase risk CVD. dietary capacity supporting system not known. Therefore, we analysed defence-related markers serum CVD patients under supplementation increased snacks. Patients were split into groups according inclusion criteria intervention (DI) design. concentration GPx GST (glutathione-S-transferase) was measured before after 6-week DI. During DI, control (CON) subjects total diet 48% 21%, respectively. It resulted significantly decreased (from 3.71 2.54 U/g Hb, p < 0.05) an 33.90 38.3 U/L). results CON group did reveal significant GPx. This study demonstrated that might associated with improving glutathione-related defence. However, conclusion substantial due small sample used this study.
