Sophie's Key Takeaways
  • Oxidative stress occurs when there is an imbalance between free radicals and antioxidants in the body.
  • It contributes to ageing, inflammation, and the progression of chronic diseases.
  • Lifestyle changes and antioxidant-rich foods can help mitigate oxidative stress.

What Is Oxidative Stress?

Oxidative stress arises from an imbalance between reactive oxygen species (free radicals) and the body’s ability to neutralise them with antioxidants.

  • Free Radicals: Molecules with unpaired electrons that can damage cells, proteins, and DNA.
  • Antioxidants: Compounds that neutralise free radicals, protecting against cellular damage.
