Free radical damage occurs when unstable molecules, known as free radicals, interact with healthy cells in the body. These free radicals can be generated from various sources, including pollution, radiation, and even normal metabolic processes. When they react with cell components like DNA, proteins, or lipids, they can cause oxidative stress, leading to cellular damage. This damage can contribute to various health issues, including aging, cancer, and heart disease. Antioxidants, found in many fruits and vegetables, help neutralize free radicals, reducing their harmful effects. Maintaining a balanced diet rich in antioxidants can support overall health and mitigate free radical damage.
