Oxidative stress is an imbalance of free radicals and antioxidants in your body that leads to cell damage . It plays a role in many conditions like cancer, Alzheimer's disease and heart disease . Toxins like pollution and cigarette smoke can cause oxidative stress, while foods rich in antioxidants can help reduce it. Oxidative stress is a phenomenon caused by an imbalance between production and accumulation of oxygen reactive species ( ROS ) in cells and tissues and the ability of a biological system to detoxify these reactive products. ROS can play, and in fact they do it, several physiological roles (i.e., cell signaling), and they are normally generated as by-products of oxygen metabolism; despite this, environmental stressors (i.e., UV , ionizing radiations, pollutants, and heavy metals ) and xenobiotics (i.e., antiblastic drugs) contribute to greatly increase ROS production, therefore causing the imbalance that leads to cell and tissue damage (oxidative str...
