[ RadSafe ] A little radiation is good for mice

[Robert J Gunter]

Greetings All,

I am familiar with lots of studies looking at the generally beneficial
effects of ingesting anti-oxidants.  The question not answered by this is
whether or not even more benefit occurs from a diet rich in anti-oxidants
and whether there is a stronger health gain from that than from radiation
exposure.

Anti-oxidants are also known to provide benefits from the byproducts of
oxidation as part of normal food digestion (see: "caloric restriction diet"
for the effects of digestion produced oxidants).  It is interesting in
dealing with a complex system like the body where there are many competing
mechanisms.  Which one gives the net highest beneficial effect?

A little radiation gives benefit, but the presumed cause of the benefit
(cell repair mechanism triggering), does not occur as much if the cell
damage does not occur due to the presence of anti-oxidants.  Does ingesting
vitamin C for example give an even higher health benefit than getting
irradiated?

Just when you thought you had it all figured out ...

  A little radiation is good for mice
Low doses of radioactivity led to healthier pups

"But radiation acts differently at low doses, producing health benefits for
mice with an unusual genetic makeup ... Antioxidant vitamins, such as
vitamins C and E, erased those health gains."
