My worry with jumping straight to questions like that is that it doesn't seem terribly clear to me that this is a case where any hypothetical correlation is due to causation. I'm no doctor, but my vague understanding is that relevant biochemistry is arranged such that it would more likely that they simply share a common cause. And the reason why that matters is that getting the causality wrong might promote incorrect conclusions about how best to address the problem, and that that in turn might lead to ineffective or even harmful recommendations. Which I don't think is a mere academic concern; it seems that that's a mistake that health researchers (or at least health pundits) just keep making over and over and over again.
