Free Radicals

Free radicals are molecules with unpaired electrons that have the potential to cause damage to the cells of our bodies. They are produced as by-products of metabolic processes and can be found in the environment. The most common free radicals are reactive oxygen species, coupled with nitrogen-based radicals. They are capable of reacting with any type of molecule, leading to damage in the form of oxidation, to DNA, lipids and proteins. This damage can lead to a range of diseases such as cancer, macular degeneration and inflammatory conditions. Antioxidants, such as vitamins A, C, and E, help to neutralize the damaging effects of free radicals. Therefore, a diet rich in antioxidants is important for maintaining good health.
