Anti oxidants are fighters with a bad oxygen.

A why we pare aging and health loosing, a theory is a one as about a free radicals, into a cellular metabolism processes at organism  manufacturing an initial for oxygen,which having such chemo activity, that give an oxidating processes,were cells damaging.

At organism having an anti oxidant system, which recognizes a free radicals and neutralizes theirs, with age and in damage a forming oxygen goes get out of control, but we are worsening this, if eating bad meal,smoking, drinking alchokol, and oxidant process,with a free radicals effect will lead to display a different chronic spreading damages thanks to display a free radicals,as are cardiovascular system, diabetes, pancreatitis, cataracts, rheumatoid arthritis ,were display a sensitiveness to infections,tumors, inborn defects for a future generation.
And when a found an taking part of active oxygen in mechanism of aging  and damages display, and found a drugs against theirs, antioxidants kill an abundant of oxygen,and leads to norm a work of organs,systems, effecting on the cellular level,theirs many of having in fish, blueberry,,tomatoes, green tea,brocolli, nuts, and eating right you can raise immunity,prevent tumors,and aging delay. And do not a fast eating theirs, we having as different anti oxidants produce, as to know a combination of substances,as milk products neutralize anti oxidant  qualities for fruits, ass green tea and red wine, and anti oxidants meal avoiding for asthmatics.
