Food Sources of Natural Chemopreventive Agents: Chemopreventive Agents and Effects on Endogenous Antioxidants Victor Olusegun Rowland

Many constituents in our diet are chemopreventive agents in animal models. Experiments with cultured cells revealed various potential mechanisms of action . Epidemiological observations show lower cancer rates in people whose diets are rich in fruits and vegetables . This has led to the theory that diets rich in fruits and vegetables contain a high concentration of antioxidants which are thought to be chemopreventive. Evidence based studies have also revealed that many debilitating ailments such as alzheimers disease,schizophrenia etc show a remarkable increase in free radicals. It may then be conceived that addressing oxidative stress may be a prerequisite to preventing or even attenuating many degenerative diseases. Experiments in animal models have revealed that there is a positive corellation between the oxidative state of the body and degenerative diseases.
