Antioxidant Defense Mechanisms in Diabetes

In response to increased oxidative stress in diabetes, the body employs various antioxidant defense mechanisms to counteract free radical damage. Key antioxidants, including glutathione, superoxide dismutase (SOD), and catalase, work synergistically to neutralize ROS and maintain redox balance. However, in diabetic patients, these defense mechanisms are often overwhelmed due to chronic hyperglycemia and inflammation, leading to an insufficient antioxidant response. Research highlights the potential of dietary antioxidants, such as vitamins C and E, and polyphenols, to bolster the body's antioxidant capacity. Enhancing these defenses through lifestyle modifications or supplementation may play a crucial role in reducing oxidative stress and improving outcomes in diabetes management.
