Antioxidants are compounds that help to protect cells in the body from damage caused by free radicals. Free radicals are unstable molecules that are produced naturally in the body as a result of normal metabolic processes and can also come from external sources, such as pollution and radiation. Free radicals can cause damage to cells and contribute to the development of chronic diseases, such as heart disease, cancer, and diabetes.
Antioxidants work by neutralizing free radicals and helping to prevent the damage they can cause. They can be found in a variety of foods, including fruits, vegetables, nuts, seeds, and whole grains. Some common types of antioxidants include:
- Vitamins C and E: These vitamins are found in a variety of fruits and vegetables and can help to protect cells from free radical damage.
- Beta-carotene: This antioxidant is found in orange and yellow fruits and vegetables, such as carrots and sweet potatoes.
- Lycopene: This antioxidant is found in red fruits and vegetables, such as tomatoes and watermelons.
- Selenium: This mineral is found in nuts, seeds, and whole grains and can help to protect cells from free radical damage.
- Polyphenols: These compounds are found in green tea, red wine, and certain fruits and vegetables and have potent antioxidant properties.
Incorporating a variety of foods that are rich in antioxidants into your diet can help to support overall health and reduce the risk of chronic diseases. Some studies have also suggested that antioxidant supplements may have health benefits, but more research is needed to fully understand their potential effects. It’s generally recommended to get antioxidants from a well-balanced diet rather than supplements, as it’s not clear whether supplements provide the same benefits as the antioxidants found in whole foods.
