I don't understand people freaking out over this - outside of a purely political reflex - hell hath no fury like taking away nerds' Mountain Dew and Flamin' Hot Cheetos.
Nor do I understand the negative reactions to new restrictions on SNAP - candy and sugary drinks are no longer eligible.

There was a story about this in the NYT recently (can't find it) and IIRC, it basically said protein is out and fiber is in. It wasn't that simple, but that was my takeaway.
Just because an article comes from Harvard doesn't mean it's correct -- Harvard scientists were also behind the original food pyramid, and were likely paid off by the sugar industry.
I sometimes wonder if the complexity of the human body doesn't stop us from seeing things that can have great positive effect on a set of people because it's counteracted by the effect on another set of people so the result in the whole is cancelled out. I now wonder if the statistic methods used in these studies take this into account.
All this to say that I approve of controlled self-experimentation, but you need to be very rigorous and brutally honest. Most people are not.
but it's tricky to figure out and i assume the consensus rules are good enough for most people
