What Are Antioxidants?
Antioxidants are compounds capable of preventing or delaying free radical damage to cells. Free radicals are unstable molecules the human body naturally produces as a byproduct of converting food into energy. They also react to various environmental stressors, such as air pollution and sunlight.
When the body becomes overwhelmed with harmful free radicals, oxidative stress occurs. The process causes harm to cells, triggering several diseases.
A balance between antioxidants and free radicals is necessary for normal function. Therefore, dietary antioxidants serve as beneficial substances in managing human diseases.
In fighting free radical damage, antioxidants help reduce the risk of heart disease, the development of cancer cells, and more.
Most antioxidants are naturally-occurring and are present in certain foods. Additionally, concentrated forms of antioxidants are added to dietary supplements.
What Are the Health Benefits of Antioxidants?
A diet high in antioxidants can support and improve your overall health in multiple ways. There is a long list of reasons why antioxidants are good for you. Ultimately, the top advantages of eating antioxidant-rich food products come down to the following:
- Cell protection: The primary health benefit of dietary antioxidants is their ability to protect the cells from free radical damage. Antioxidants prevent the formation of radicals, scavenge them, or help decompose them.
- Disease-fighting properties: Free radical damage contributes to the cause of many chronic health problems, including cardiovascular and inflammatory diseases. Therefore, antioxidants may reduce the risk of many diseases, notably heart disease and some cancers.
It’s crucial for people who fast intermittently to include antioxidants within the eating window to maintain good health.

What Happens if You Don’t Get Enough Antioxidants?
Although your body naturally produces certain antioxidants, you must obtain essential antioxidants from dietary sources. If you don’t get enough antioxidants, your body is more prone to cellular damage and the risk of developing chronic diseases.
An imbalance of antioxidants and free radicals causes oxidative stress. Over time, this stress can damage your DNA and other vital cells, increasing your risk of certain diseases.
Low levels of antioxidants, including vitamin E and C, can cause an antioxidant deficiency. Symptoms of a deficiency include:
- Low levels of antioxidants can contribute to fatigue and muscle atrophy.
- A vitamin C deficiency can cause anemia, bleeding gums, easy bruising, and slow wound healing.
- Vitamin E deficiency can cause muscle weakness, loss of feeling in the arms and legs, vision problems, and a weakened immune system.
- Beta carotene converts into vitamin A, and a vitamin A deficiency can cause night blindness, dry skin, and dry eyes.
