The Free Radical Theory

The Free Radical Theory (FRT) is a theory in neurology that explains the underlying physical mechanism of the degenerative diseases of the central nervous system. FRT proposes that certain free radicals form in nerve cells and, over time, lead to damage of the cells. These damaged cells are thought to be responsible for the onset of neurological disorders such as Alzheimer’s, Parkinson’s disease, and Lou Gehrig’s disease, among others. Free radicals are highly reactive molecules that are produced naturally by metabolic processes in the body, as well as through environmental exposure to toxins like pesticides and radiation. Within the cells, free radicals can damage DNA, membranes, and other essential components, thus leading to unhealthy cell death or dysfunction. The damage from these free radicals can build up over time and is thought to be responsible for the onset of neurological disorders. In addition, FRT suggests that the anti-oxidant properties of certain vitamins and minerals can reduce free radicals, reducing their harmful effects on the nerve cells. In turn, this could protect and even reverse the damage caused by nerve cell degeneration and subsequently reduce symptoms associated with neurological disorders. This theory, however, is still under debate and research is currently in progress to better understand the anti-oxidant action of vitamins and minerals and their potential role in preventing or treating neurological disorders. FRT often draws support from observational and epidemiological studies which suggest that diets incorporating a vast variety of fruits and vegetables may reduce the risk and progression of neurological disorders. Although further evidence is needed to establish conclusive links between the FRT and neurological disorders, the current evidence is encouraging. Future research should focus on discovering the underlying pathways of the diseases, as well as the most effective dietary interventions and anti-oxidant treatments.
