Foods rich in antioxidants include a variety of fruits and vegetables. Some of the top sources are berries, such as blueberries, strawberries, and blackberries, known for their high levels of vitamin C and flavonoids. Leafy greens like spinach and kale also offer a wealth of antioxidants. Moreover, nuts, particularly walnuts and pecans, and dark chocolate are valuable sources. Consuming a diverse range of these antioxidant-rich foods can help combat oxidative stress and protect against chronic diseases, enhancing overall health.
