ABSTRACT:
minimally refined cereals is associated with lower risk for chronic degenerative diseases. Since oxidative stress is common in chronic degenerative disease it has been assumed that dietary antioxidants may explain this protective effect. Highly reactive molecules are called free radicals. In living organism the levels of free radicals and other reactive species are controlled by complex web of antioxidants defenses. These free radicals are produced in body due to aerobic metabolism. High consumption of extra-virgin olive oils, which are particularly rich in these phenolic antioxidants (as well as squalene and oleic acid), should afford considerable protection against cancer (colon, breast, skin), coronary heart disease, and ageing by inhibiting oxidative stress. It is one of the most potent antioxidants among dietary carotenoids. Dietary intake of tomatoes and tomato products containing lycopene has been shown to be associated with a decreased risk of chronic diseases, such as cancer and cardiovascular disease. The reason is to know the role of antioxidants in health and disease.
