In recent years, there has been a great deal of attention toward the field of free radical chemistry. Free radicals are produced by cellular metabolism involve oxidation, environmental and other factors, with very high reactivity. Antioxidants work by stabilizing free radical induced destabilization of other molecules and cell damage by preventing their formation, scavenging them. Antioxidants cannot be formed by body spontaneously. Instead, we must consume them in our diet. This manuscript provides a brief overview on ROS mediated cellular damages, role of dietary antioxidants and background information about lycopene and resveratrol in many different diseases. Lycopene is a phytochemical that belongs to a group of pigments known as carotenoids. It is allegedly a more effective antioxidant than other of its carotenoid cousins, also known to help prevent as well as the prevention and treatments of many illnesses and diseases. Grapes are amazingly versatile; the fruit and it’s skin, seeds and leaves are all put to good use. Resveratrol, a popular supplement is extracted from the skin of the grape with multiple beneficial effects on human body.
