Antioxidants
Definition
Antioxidants are substances that help protect your cells against the effects of free radicals, which are molecules produced when your body breaks down food or is exposed to tobacco smoke and radiation.
Scientific / Technical Definition
Antioxidants are molecules capable of inhibiting the oxidation of other molecules. Oxidation is a chemical reaction that can produce free radicals, leading to chain reactions that may damage the cells of organisms. Antioxidants such as vitamins C and E, selenium, and beta-carotene neutralize free radicals by donating an electron, ultimately reducing oxidative stress.
Benefits
- Reduce the risk of chronic diseases such as heart disease and cancer.
- Protect cells from damage caused by free radicals.
- Support immune system function.
- Delay the aging process by reducing accumulation of cell damage.
- Improve skin health and appearance.
Examples
- Vitamin C-rich foods like oranges and strawberries.
- Vitamin E-rich foods such as almonds and sunflower seeds.
- Beta-carotene in carrots and sweet potatoes.
- Selenium-rich foods like Brazil nuts and fish.
Additional Information
- Effects: Antioxidants help to mitigate the effects of oxidative stress, which is linked to various diseases and aging.
