Hi. I was reading about antioxidants earlier and they speak about the free radicals oxidizing everything, and so the antioxidants prevent this by happening by undergoing oxidation with them. Now when they're saying oxidation do they really mean oxidation/reduction, because as far as my understanding goes whenever there's an oxidation there's a reduction. Are they just making it simpler by saying oxidation with the implication that the free radicals are good oxidizing agents? If something is a good reducing agent, and something else is a good oxidizing agent, are they both effective in the same ways in terms of reacting with some other chemical?
