We were discussing this in work today, as the lab I'm in works on oxidative stress.
I think this is really interesting, but it annoys me that the BBC article says that insulin sensitivity was *restored* in the group who weren't taking vitamins, and the journal article actually talks about an increase in sensitivity in one group that wasn't observed in the other, which is quite a different thing. Both groups started out with the same level of insulin sensitivity, and they were considered to be non-diabetic and not insulin resistant. They're also on quite high levels (1000mg vit C, and 400I/U vit E). Umm, I'll stop ranting now... 😛
I think this is really interesting though, and I wonder what results they would get if they did the same thing on people who were already insulin resistant. It's also interesting to note that they had a group who were already exercising a lot before the study, and a group who weren't, and the group who were exercising before had higher insulin sensitivity, and they didn't lose that when they started taking the vitamins.
*takes off science hat* 😱
