Antioxidants are molecules that fight free radicals in your body. These unstable compounds can cause harm if their levels become too high. Free radicals are linked to various illnesses, including diabetes, heart disease, and cancer. Your body has its own antioxidant defenses, but you can also find antioxidants in food, especially in fruits, vegetables, and other plant-based whole foods. Vitamins E and C are examples of effective antioxidants. They neutralize free radicals, preventing damage to your cells. When free radicals outnumber antioxidants, it can lead to a state called oxidative stress, which can damage your DNA and other essential molecules. Maintaining a balance between free radicals and antioxidants is crucial for overall health.
