Before we understand what antioxidants are and the role they play in our overall health and wellbeing, let us first understand what free radicals are.

Free radicals are the unstable molecules that are formed as a result of the various chemical reactions that occur in our body – like food consumed getting converted into energy, exposure to sunlight, pollution, radiation, etc.

These are unstable because they contain unpaired electrons and in order to become stable, they try to steal these electrons from other molecules. While doing so, they cause extensive damage to the cells of the body and also trigger harmful chain reactions, which are termed oxidative stress or oxidative damage.

To make matters worse, these radicals create a ripping effect that is once a free radical is formed, it starts creating many more free radicals in the process.

Role of Antioxidants

Antioxidants are our body’s protectors and help to neutralize these free radicals and stop them from causing damage to our bodies. Coming in different shapes and sizes, they donate electrons to these free radicals, thereby making them stable. In some cases, they also play a crucial role in degrading these radicals and render them harmless.

By doing so, they also help to protect the body from dangerous ailments like cardiovascular diseases, cancer, Parkinson’s, Alzheimer’s, etc.

Best Sources of Antioxidants

Studies have proved that many plant-based foods act as rich sources of antioxidants. Often it is observed that the most colourful foods have the most antioxidants.

Some common antioxidants include:

  • Vitamin C
  • Vitamin E
  • Beta-carotene

  • Clove
  • Cinnamon
  • Turmeric
  • Cumin
  • Cocoa
  • Thyme and
  • Ginger

While the formation of free radicals is a normal phenomenon, it is, in fact, the oxidative stress that causes more damage than good.

  • Affect cell walls
  • Cause LDL cholesterol stick to blood vessels
  • Damage the DNA, to name a few
