Loading up your plate with a variety of antioxidant-rich foods is one of the best things you can do for your overall health. Antioxidants come with a long list of benefits, including protecting against premature aging, promoting youthful skin, supporting the immune system, fighting chronic diseases — the list goes on and on! And though you may be familiar with the term ‘antioxidants,’ you may not know exactly what they are (or what makes them so powerful). Considering they’re so powerful (and easy to obtain from a colorful plant-based and whole foods diet), we’re breaking down all you need to know! 

What Are Antioxidants & Why Are They So Powerful?

What are antioxidants, exactly? Simply put, antioxidants are natural compounds found in many nutrient-rich foods that work to protect our bodies against free radical damage. Free radicals are unstable molecules that wreak havoc in the body, causing cell damage and contributing to things such as inflammation, chronic disease, and enhanced aging. While normal metabolic processes can contribute to free radical production, external factors — such as chronic stress, smoking, drugs, pesticides, and environmental pollutants — have been shown to increase free radical production in the body. 

Luckily, by loading up on antioxidant-rich foods, you can help keep free radicals in check in order to prevent oxidative stress and cell damage.

That said, let’s take a look at some of the most powerful antioxidants. Plus, learn how to obtain them from your diet! 

The Most Powerful Antioxidants & How To Obtain Them Through Your Diet


Best known for its heart-healthy benefits, resveratrol is a potent polyphenol antioxidant, or in simpler terms, a protective and powerful plant compound with antioxidant-rich benefits.

In terms of heart health, resveratrol has been shown to lower inflammation, reduce LDL cholesterol, and even protect against and improve symptoms of cardiovascular disease!
