What is the role of antioxidants in nutrition?

Antioxidants play a crucial role in nutrition by protecting the body from free radical damage. Free radicals are highly reactive molecules that can damage cells, proteins, and DNA, leading to oxidative stress, which is linked to various chronic diseases, including cancer and heart disease. Antioxidants counteract this damage by neutralizing free radicals, thus contributing to overall health and reducing the risk of these diseases.

The importance of antioxidants extends to their roles in supporting the immune system and promoting healthier aging. Dietary sources of antioxidants include fruits, vegetables, nuts, and whole grains, which are rich in vitamins such as vitamin C and E, selenium, and other phytonutrients that exhibit antioxidant properties. By neutralizing free radicals, antioxidants help maintain cellular integrity and function, which is vital for optimal health.

In contrast, other choices, while relevant to nutrition, do not accurately define the primary function of antioxidants. For instance, boosting energy levels or aiding muscle recovery may involve other nutritional components such as carbohydrates, proteins, and specific vitamins or minerals, but not directly related to the antioxidant function. Similarly, while some antioxidants can influence vitamin absorption, this is not their main role; instead, they primarily protect the body from oxidative stress. Thus, the distinct function of antioxidants as
