Antioxidants- Free Radicals
Antioxidants are substances that protect the body's cells from damage caused by free radicals. Free radicals are unstable molecules that are produced as a byproduct of normal metabolic processes, as well as by environmental factors such as pollution and exposure to radiation. These unstable molecules can cause damage to cells and contribute to the development of chronic diseases, including heart disease, cancer, and Alzheimer's disease.
Antioxidants work by neutralizing free radicals and preventing their damaging effects. Some of the most important antioxidants in the human body include:
-
Vitamin C: Vitamin C is a water-soluble antioxidant that helps protect against cellular damage from free radicals.
-
Vitamin E: Vitamin E is a fat-soluble antioxidant that helps protect the body's cell membranes from damage.
-
Beta-carotene: Beta-carotene is a precursor to Vitamin A and has antioxidant properties.
-
Selenium: Selenium is a trace mineral that acts as an antioxidant and helps prevent cellular damage.
-
Glutathione: Glutathione is an antioxidant that is produced by the body and helps protect against cellular damage.
-
Polyphenols: Polyphenols are a group of compounds found in plant-based foods, including fruits, vegetables, whole grains, and tea, that have antioxidant properties.
The body also has a variety of other antioxidant systems that help protect against cellular damage, including enzymes such as superoxide dismutase and catalase.
Antioxidants are important for overall health and well-being, and can be obtained from a balanced diet that includes plenty of fruits, vegetables, whole grains, and lean protein, as well as from antioxidant supplements. However, it is important to note that not all antioxidant supplements have been shown to be safe and effective, and some may even have harmful effects. Before starting any new supplement regimen, it is always best to consult with a healthcare professional to ensure safety and appropriate dosing.
