Conclusion

Introduction 

Molecules inhibiting the oxidation of other molecules are antioxidants. A chemical reaction producing free radicals is known as oxidant. Oxidants leads to chain reactions that damage cells. Antioxidants neutralize these free radicals by donating electrons, preventing further cellular damage. 

When there's an imbalance between the production of free radicals, oxidative stress occurs. Antioxidants play a crucial role in maintaining cellular health by counteracting oxidative stress. They protect cells from damage caused by free radicals, which, if left unchecked, can harm DNA, proteins, and lipids. This damage contributes to various chronic conditions, including cardiovascular diseases, neurodegenerative disorders, and cancer.

By scavenging free radicals and stabilizing reactive molecules, antioxidants help prevent and repair cellular damage. Incorporating a diverse range of antioxidant-rich foods into one's diet is essential for supporting the body's defense mechanisms against oxidative stress and promoting overall health.
