What is the main function of antioxidants in the diet?

The primary function of antioxidants in the diet is to protect cells from damage. Antioxidants are compounds that help neutralize free radicals, which are unstable molecules that can cause oxidative stress leading to cellular damage. This oxidative stress is associated with various health issues, including chronic diseases, aging, and inflammation.

Antioxidants work by donating electrons to free radicals, thus stabilizing them and preventing them from causing harm to cellular components like DNA, proteins, and lipids. Common dietary sources of antioxidants include fruits, vegetables, nuts, and whole grains, which are rich in vitamins such as vitamin C and E, as well as other phytochemicals like flavonoids and carotenoids.

This protective role is crucial for maintaining overall health and reducing the risk of diseases, making the consumption of antioxidant-rich foods central to a nutritious diet.
