Antioxidants are primarily known for protecting the body from what?

Antioxidants play a crucial role in safeguarding the body by neutralizing free radicals, which are unstable molecules that can cause oxidative stress. This oxidative stress can lead to cellular damage, inflammation, and various diseases, including cancer and heart disease. Free radicals are produced naturally in the body during metabolic processes, but they can also be induced by external factors such as pollution, radiation, and certain chemicals.

The mechanism of how antioxidants work involves donating electrons to free radicals, thereby stabilizing them and preventing them from causing further damage to cells and DNA. By reducing oxidative stress, antioxidants contribute significantly to overall health and may help in preventing chronic diseases.

While viruses, bacteria, and toxins can indeed harm the body, the primary recognition of antioxidants is in their protective role against free radicals. This specific action is what makes antioxidants a key focus in discussions of nutrition and health.
