Like others, I wish I had reliably robust experimental results to point as the basis for much of what I believe in life. Instead I must rely on the perceived credibility of other sources. So I challenge much of what I see as a matter of good logical practice.
I’m very glad to see @amwassil initiate this thread and hope to follow along. But in this spirit, I’ll quibble (slightly) with this reasoning…
I’m unconvinced that genetic “dies” are ever cast. Between mutations, selection pressures, and epigenetics, it seems the more we learn about genetic lineage the more we come to see how remarkably malleable our DNA fingerprints are.
The fact that we can convert our mitochondria to burn “this” vs “that” fuel (viz. fat adaptation) in just a matter of weeks suggests to me the notion that our distant ancestors ate a certain way and therefore we’ve been set into a preconfigured dietary mode for maximum health seems flawed.
Observation across the globe/cultures strongly supports the conclusion that humans are natural omnivores - and can survive on any number of food groups for decades. Whether that’s “thriving” remains the interesting and open question.
Looking forward to reading whatever science is available. My guess is there’s very little indeed that’s useful on an n=1 basis.
