What little I know is from from talking scientists involved in this area who I understand to believe it is far from a known issue, so I'd be surprised to see your cites (but always happy to be wrong!)
Why don't you start by showing your citations that say otherwise?
There isn't anything resembling scientific consensus on huge swathes of this stuff. Anything as straightforward as the claim I was responding to is an extraordinary claim. As such it requires support.
Where I'm coming from is this:
- If you do any sort medical research you quickly learn that demonstrating even simple causal relationships is difficult. Demonstrating it for something as difficult to control for properly as diet is extremely difficult, and it mostly fails.
- The vast majority of information on dietary effects easily available to the lay public is, to put it bluntly, mostly marketing B.S. of various kinds.
- I was probably being unfair to the original comment but find it frustrating the number of times you see "Oh, I'll apply flavor-of-the-year, wave my hands about the mechanism, and voila, the answer is probably X".
I probably shouldn't have said anything, as it's unlikely to be productive.
