In my experience, in all of academia, Harvard dietary research is the shoddiest and the most biased, given their historical strong ties to Seventh Day Adventists which are notoriously pro-vegetarianism and pro-veganism.

Dietary science is as rigorous as astrology, and then there's commercial and religious interests to consider. The same institute can post research showing how a particular diet is better against another, and months later, publish the exact opposite. Given it's all tantamount to bullshit, N=1 anecdotes have greater validity than anything that's posted in press releases.

Wikipedia suffers from the same bias problem in dietary matters. It still defines low carb as a "fad", for heaven's sake.

(LOL at flagging OP's comment - what's going on these days that anything slightly disagreeing with the hivemind is worth being shadow-banned?)
