What is the role of antioxidants in the diet?

Antioxidants play a vital role in the diet by protecting the body from oxidative stress and damage caused by free radicals. Free radicals are unstable molecules that can damage cells, proteins, and DNA, leading to various health issues, including chronic diseases and aging. Antioxidants neutralize these free radicals, thereby reducing their harmful effects on the body. This protective action is crucial for maintaining overall health and may contribute to the prevention of oxidative stress-related conditions such as heart disease, cancer, and neurodegenerative disorders.

In addition to their protective roles, antioxidants can be found in various foods, particularly fruits, vegetables, nuts, and whole grains, where they contribute to the overall health benefits associated with a balanced diet. While fiber, protein absorption, and energy sources are important dietary components, they do not encompass the specific protective role that antioxidants fulfill in combating oxidative stress.
