> It's quite insightful to see how this error then spawned a whole new series of 'approved' explanations for why wine was supposed to be healthy for you, such as antioxidants or whatever.

Your analysis provides a very nice example of how science studies can be meaningless. And that this isn't a problem, as long as someone is making money. How many years did we see yet another study being rolled out about France, red wine, red wine extracts in pill form, etc. And yet all that literature is based on a pretty obvious false assumption. That no one was inclined to correct.
