What Is an Antioxidant and Why Is It Important?

Categories health antioxidants free-radicals oxidative-stress

Antioxidants are molecules that help protect the body from damage caused by free radicals, which are unstable molecules that can harm cells, proteins, and DNA. Free radicals are produced naturally in the body as a result of cellular metabolism, but their levels can increase due to external factors such as pollution, stress, smoking, and radiation.

Antioxidants neutralize these free radicals by donating electrons, which helps prevent a chain reaction of damage. This process is crucial because excessive free radicals can lead to a condition known as oxidative stress, which is associated with chronic diseases such as cancer, heart disease, and diabetes, as well as aging.

Sources of antioxidants include fruits, vegetables, nuts, seeds, and whole grains. Common antioxidants include vitamin C, vitamin E, beta-carotene, and selenium. Incorporating antioxidant-rich foods into your diet can help enhance your overall wellness and reduce the risk of chronic diseases.

In summary, antioxidants play a vital role in maintaining health by combating free radicals and preventing oxidative damage. Adopting a lifestyle rich in antioxidants can lead to better health, increased vitality, and prevention of disease.
