What Are Antioxidants? Benefits and Antioxidants-rich Foods 

April 14, 2022

Your body’s cells face internal and external threats from viruses, infections, and free radicals every day. Some cells can heal from the damage, while others cannot. Scientists believe that free radicals can contribute to the aging process and damage the DNA. They also play a part in causing cancer, diabetes, and heart disease.

Antioxidants play an essential role in preventing such diseases. 

So, “what is a good antioxidant?” Many antioxidants provide different health benefits, so choosing one can be challenging. However, you can go through their functions and benefits and choose the supplements according to your requirement.

What are antioxidants?

Antioxidants are substances that can combat or inhibit oxidative reactions. They can slow down or prevent free radical damage to cells. They are often referred to as “free radical scavengers.”

The antioxidant enzyme systems can be classified as endogenous enzymes produced by our bodies and exogenous enzymes introduced into the body through food or supplements.

Vitamins, carotenoids, and phenolic compounds are natural antioxidants found in fruits and vegetables.

Benefits of Antioxidants

Fight Free Radicals

As mentioned earlier, antioxidants fight against free radicals and prevent various diseases. They provide an electron to free radicals, thus stabilizing them and making them harmless.

Improve Mental Health

The brain is particularly vulnerable to free radicals. They cause damage, especially to the hippocampus, the region involved in learning and memory. In addition to harming hippocampus cells, oxidative stress also reduces neurogenesis (new brain cell generation). 

Antioxidants can be used as part of the treatment of neuropsychiatric disorders. Researchers believe eating antioxidant-rich foods can help reduce the symptoms of depression and anxiety and improve your mental health.

Improve Your Eyesight

The onset of AMD in adults over 60 years of age is one of the most common causes of permanent vision loss. Consuming a diet high in antioxidants can decrease your chances of getting AMD by up to 25%. 

Those who have already developed AMD can get more out of their vision by consuming antioxidant-rich foods or supplements. They may also help prevent cataracts.

Support Healthy Aging

There is a close relationship between oxidative stress, aging, and inflammation. Antioxidants are crucial for protecting DNA as well. By eating a variety of antioxidant-rich foods, you can delay age-related diseases. They reduce oxidative stress and inflammation, thereby preventing DNA and telomere damage.
