Metabolic processes in the body produce byproducts that can be harmful if accumulated. For instance, during normal cellular respiration, reactive oxygen species (ROS) are generated, which can damage DNA, proteins, and lipids. The body's antioxidant systems usually neutralize ROS, but when overwhelmed, oxidative stress occurs, leading to potential carcinogenesis. This highlights the importance of maintaining a balanced diet rich in antioxidants to support cellular health.
