By itself, that fact conveys nothing. You could've said, "Every time the "NSA is spying on everyone" comes up, it seems to be Glenn Greenwald talking about it".
When it comes to Big Food (or Big Pharma, Big Insurance etc.), I'd prefer - at the very minimum - taking any claims against them at face value instead of dismissing them outright. Of course, follow it up with your own research.
If that's the only way you can validate claims and counterclaims made by others, please go ahead.
Less resourceful people, like me, prefer a more common-sense approach of searching & reading multiple authors & articles to arrive at something they feel could be reasonably close to the truth.
>You could've said, "Every time the "NSA is spying on everyone" comes up, it seems to be Glenn Greenwald talking about it".
Because Greenwald is in possession of a secret stash of documents leaked to him and only a few other people on the planet have access to those documents. Are you saying that Lustig has some secret data about fructose that only he knows about?
It conveys that the opinion you heard a hundred times isn't a hundred people having the same opinion; it's one person having the opinion a hundred times.
