avoiding antioxidants during RT

I'm about to start RT on a hand, and a nurse advised me to avoid consuming antioxidants for a few weeks. She said that while there have been no studies to prove it, there is a theory that some of the beneficial effect of RT arises from the generation of oxidants. This theory suggests that one should avoid supplementing the diet with antioxidants. I've read something about this in a nutrition article http://jn.nutrition.org/content/134/11/3207S.full

What I'm not sure about is how long to avoid antioxidants. The nurse suggested avoiding antioxidants for SEVERAL WEEKS AFTER RT. I'm a bit skeptical about that. The article that I linked above suggests that the radiation-induced antioxidants have a lifetime of LESS THAN A SECOND -- so it seems to me that one should just avoid consuming antioxidants before RT so that it's not present in the body during RT, but one could consume them without problem immediately after RT is finished.

I'm wondering what others have been told.

Re: avoiding antioxidants during RT

I just finished RT about three weeks ago. I was told nothing about antioxidants.

Re: avoiding antioxidants during RT

I was told nothing about avoiding antioxidants. If avoiding antioxidants ever is a factor in getting RT, I'm wondering if maybe it would be for radiation for an aggressive form of cancer.

You might want to talk with the doctor/radiologist about this.

Re: avoiding antioxidants during RT

I have not heard of this and it was not mentioned to me either although when I think about it from a scientific perspective, it may make some sense. While it is difficult conceptually to see how RT can have some impact so quickly in some people, oxidative damage to tissue following radiation may be responsible. Such damage may also be responsible for any side effects. The longer term benefit of RT probably comes from the slowing down or killing of feral fibroblasts that are laying down extra connective tissue.

The ingestion of antioxidants is of questionable value anyway (unless one is taking large supplements) so intuitively I suspect that it makes no difference. No need to stop drinking green tea during RT, I didn't and RT worked for me.
