Antioxidants are compounds that help protect the body from oxidative stress caused by free radicals. They neutralize harmful molecules that can lead to cellular damage and contribute to various diseases, including cancer and cardiovascular conditions. Consuming antioxidant-rich foods, such as berries, nuts, and leafy greens, is beneficial for overall health, supporting immune function and promoting longevity. Incorporating these foods into a balanced diet enhances well-being and reduces disease risk.
