What is an antioxident nutrient?

An antioxidant nutrient is a substance that helps protect the body from oxidative stress by neutralizing free radicals—unstable molecules that can damage cells and contribute to aging and various diseases. Common antioxidant nutrients include vitamins C and E, beta-carotene, and selenium. These nutrients are found in various foods, particularly fruits, vegetables, nuts, and whole grains, and play a crucial role in supporting overall health and preventing chronic illnesses.
