Introduction
In today’s fast-paced world, maintaining good health is more important than ever. One of the best ways to support your body is by including antioxidant-rich foods in your diet. But what exactly are antioxidants, and why are they so beneficial? Let’s break it down in simple terms.
What Are Antioxidants?
Antioxidants are natural compounds that help protect your body from damage caused by free radicals. Free radicals are unstable molecules produced in the body due to factors like pollution, stress, smoking, and even normal metabolic processes.
When free radicals build up, they can cause oxidative stress, which is linked to ageing, inflammation, and chronic diseases like heart disease, diabetes, and cancer. Antioxidants neutralise these harmful molecules, keeping your cells healthy and reducing the risk of illness.
