What are Antioxidants | Benefits of Foods Rich in Antioxidants


You may have tried to know and eat foods that are good for your heart or your stomach. But have you ever thought of eating foods that would shield your cells? Those would be the foods packed with antioxidants, a term that you may have heard before.


What are Antioxidants?

Antioxidants are compounds found in food that stop or delay damage to the cells,” Lauri Wright, Ph.D., R.D., L.D., assistant professor of nutrition at the University of South Florida, tells SELF. They are naturally found in many foods, especially plants. They help ward off cell damage by “cleaning up” or removing waste products in our cells, called free radicals before they can do harm. “Antioxidants are released from the foods we eat through digestion and travel through the bloodstream and into cells,” where they do work on free radicals, Wright explains.

Antioxidants are substances that work interactively inside and outside of the body’s cells, protecting cell membranes from the damaging effects of highly reactive molecules called free radicals.

What are Free Radicals?

Free radicals are “charged” molecules that, if not counteracted by an antioxidant, run riot throughout the body, causing irreparable damage to cell membranes and cell structures (including our DNA or genetic blueprint), driving diseases such as cancer and heart disease, and also accelerating aging. In fact, free radicals are implicated in over 60 diseases.

Antioxidants are naturally found in foods produced from plants, such as fruits, vegetables, tea, coffee, chocolates, and wines.

Though there are a relentless number of antioxidants present under the sun, the most commonly heard ones include flavonols present in chocolates, lycopene in tomatoes, resveratrol in wine, beta-carotene in carrots and catechins in green tea.

What do Antioxidants Do?

Antioxidants stop the process of oxidization, preventing the formation of free radicals before they are ever created. They can also stop free radicals from stealing the electrons from new cells, as the antioxidant compounds contain electrons that they can “donate” to complete the cellular structure of the free radicals.

They can even help to repair any cellular damage that was done by the free radicals since they were formed. They are essentially your body’s first line of defense, keeping free radicals under control, counteracting their damaging effects and removing them from your bloodstream.

While coffee is not really the richest source of antioxidants, it is definitely one of the most popular sources of antioxidants.
  • It is thought that different antioxidants benefit the body in different ways. For example, beta-carotene has been shown to have health benefits for the skin and has also been linked to good eye health.
  • Lycopene is considered to be beneficial for prostate health, including helping to reduce the symptoms of BPH, and vitamin C is a superhero when it comes to your health, boosting your immune system and protecting your heart.
