Your body’s cells face threats every day. Viruses and infections attack them. Free radicals also can damage your cells and DNA. Some cells can heal from the damage, while others cannot. Scientists believe molecules called free radicals can contribute to the aging process. They also may play a part in diseases, like cancer, diabetes, and heart disease.
Antioxidants are chemicals that help stop or limit damage caused by free radicals. Your body uses antioxidants to balance free radicals. This keeps them from causing damage to other cells. Antioxidants can protect and reverse some of the damage. They also boost your immunity.
Path to improved health
Free radicals are natural or man-made elements. They can be:
chemicals your body produces by turning food into energy
environmental toxins, like tobacco, alcohol, and pollution
ultraviolet rays from the sun or tanning beds
substances found in processed food.
You can help fight and reduce free radicals and the damage they cause. You can stop smoking, get sun exposure safely, and eat healthy. Antioxidants may also help.
Your body produces some antioxidants. You also can get them in certain foods and vitamins. Common antioxidants include:
vitamin A
vitamin C
vitamin E
beta-carotene
lycopene
lutein
selenium.
You can get most of these antioxidants by eating a healthy diet. This includes a mix of colorful fruits and vegetables. Whole grains, seeds, and nuts also provide good nutrients.
