Antioxidant-rich foods are those that contain high levels of antioxidants, which are compounds that help protect the body from damage caused by free radicals. Free radicals are unstable molecules that can lead to oxidative stress, contributing to various health issues, including chronic diseases. Common sources of antioxidants include fruits, vegetables, nuts, and whole grains. Some well-known antioxidant-rich foods include blueberries, spinach, dark chocolate, and green tea. These foods are not only beneficial for overall health but also support the immune system and may reduce the risk of certain diseases. Incorporating a variety of these foods into your diet can promote better health and well-being.
