Why are antioxidants significant in human nutrition?

Antioxidants play a crucial role in human nutrition primarily because they help counteract oxidative stress and protect cells from damage. This process involves the neutralization of free radicals, which are unstable molecules that can cause harm to cells, proteins, and DNA through oxidative reactions. By stabilizing these free radicals or preventing them from forming, antioxidants contribute to the overall health of the body.

Oxidative stress is linked to numerous chronic diseases such as heart disease, cancer, and neurodegenerative disorders. Therefore, incorporating sources of antioxidants, such as fruits, vegetables, nuts, and whole grains into the diet, is essential for maintaining cellular health and preventing damage associated with oxidative stress. This protective effect underlines the significance of antioxidants in promoting optimal health and well-being.
