Antioxidants are molecules that fight free radicals in your body.
Free radicals are compounds that can cause harm if their levels become too high in your body. They’re linked to multiple illnesses, including diabetes, heart disease, and cancer.
Your body has its own antioxidant defenses to keep free radicals in check.
However, antioxidants are also found in food, especially in fruits, vegetables, and other plant-based, whole foods. Several vitamins, such as vitamins E and C, are effective antioxidants.
Antioxidant preservatives also play a crucial role in food production by increasing shelf life.
