In chemical term, antioxidant is chemical component that can able to prevent and slow down the oxidation reaction. Oxidation reactions can occur in many ways, such as oxidation which make steel becomes rusty, change the colors of apple to becomes browns or make vegetable oil to becomes rancid.
In addition, oxidation reaction can occur in human body. For example, digestion process from food to protein and fat, respiration process which can intake air pollution such as smoke from cigarettes and UV radiation. All of these processes can make free radicals and causes many effects to human body. In fact, one chemical component cannot prevent all of the oxidation reactions. Some oxidation reactions need different antioxidant to prevent the reaction.
In other ways,

Moreover, it can slow down the aging processes. Normally, human body has capability to destroy free radicals before it can harm our body. However, when the creating of free radical is more than our capability to destroy, it will cause damage to our cell and tissue then it can harm to our healthy.
The way of reducing free radicals damage by antioxidant
1. Reducing the making of free radicals
2. Reducing damage from free radicals
Even though, antioxidant cannot fix the damage which is happened before but it can slow down the damaging, especially damaging from chronic diseases which are cells and tissues were damage for long time (mostly more than ten years). Due to this reason, most of people who have chronic diseases are middle age and elder. Consequently, everyone should have enough antioxidant in everyday in order to control the free radicals in our
