What Are Antioxidants?
The immune system is our body’s natural defense against disease causing micro-organisms. It identifies any foreign element like bacteria or viruses that invade the body and destroys them effectively.
But in some cases, the defense mechanism of the immune system is lowered or weakened due to excessive oxidative stress and damage caused by free radicals. This is where the health benefits of antioxidants come into play.
Antioxidants help in fighting free radical damage by increasing the production of antibodies and white blood cells that boost the immune system.
It also increased the production of B-cells and T-cells that fights the foreign elements and revokes the damage caused by toxins.
