These unstable molecules are produced naturally by the body as a byproduct of metabolism, but they can also be caused by exposure to environmental factors, such as pollution, radiation, and cigarette smoke Understanding antioxidants.
What Are Antioxidants?
Antioxidants are molecules that can neutralize free radicals by donating an electron to them, which stabilizes them and stops them from causing damage. Some of the most common antioxidants are vitamins C and E, beta-carotene, and selenium.
Types of Antioxidants
There are two main types of antioxidants: endogenous and exogenous. Endogenous antioxidants are produced naturally by the body, while exogenous antioxidants are obtained from external sources, such as food and supplements.
Endogenous antioxidants include enzymes such as superoxide dismutase, catalase, and glutathione peroxidase. These enzymes work together to neutralize free radicals and prevent oxidative damage.
Exogenous antioxidants can be obtained from a variety of sources, including fruits, vegetables, nuts, and seeds. Some of the most potent sources of antioxidants include blueberries, dark chocolate, pecans, and artichokes.
