Yeah, I just thought "Food sources are animal products" might be an inaccurate characterization.

As far as the link to diet goes, I'm not an expert but look at pretty much every report with suspicion unless there is a lot of independent confirmation.

From the outside "meta-analysis" seems like fishing for signal and then jumping on results as causal. But I honestly don't know if these things proceed via scientific method (I have a theory, I've devised this test, etc) or are digging up possible relations between data and then making a story to match whatever pops up.
