As you age, if you age "well," your SOD levels should be low and your vitamin E levels should be high. If you are being "oxidatively stressed," your SOD levels will rise and your vitamin E levels will drop. I've seen studies where the authors claim that PUFAs are healthy because they raise levels of particular antioxidants, but that's the body trying to counter higher levels of dangerous free radical activity. They seem to be unaware of the fact that the body makes adjustments - can they be totally unaware of the concept of adaptation? |
