If I'm gathering correctly, essentially they are implying that we evolved from vegetation digesting apes, in to meat digesting humans and then were modified by 'mutation' (*cough*, epigenetics) to digest plant fats again?
Perhaps, but kind of a roundabout way to do things don't you think evolution?
-
That's probably makes sense. I think at some point humans or even earlier ancestors were consuming moderate amount of cellulose. Then switched to mainly meat diet which resulted in tiny appendix that lost ability to digest cellulose. Then they probably discovered starchy foods that allowed them to travel long distances without heavily depending hunting meat along the way.

I think our early ancestors mostly ate fruit, pip and seed, and some amount of meat. Basically like apes, which eat lots of soluble fiber that ferments in the gut to make butyric acid, lots of insoluble fiber by eating the pips which passed through (and cleaned the gut), and which eat tiny amounts of meat like mice and bugs and what ever they can scrounge).
Then there was a shift from the rainforests to the coastlines, where they could search for shellfish in shallow waters (the bipedal height adaptation) and hunt medium sized herbivores in the nearby plains by running them down in a pack (the cardio/sweat advantage). The combination of soluble fiber to butyric acid helped us first digest the animal fat and organs in excess which grew our bodies to a powerful stature, and getting lots of omega 3s from the shallow water shellfish grew our brains.
When our brains developed enough to become smart enough to use tools to hunt, this is when we started hunting actual fish and larger animals we couldn't kill before, we became even stronger and smarter!
This is also why I believe we are naturally polyphasic sleepers, because when we moved to the coast lines, the best time to catch shellfish is at night, while the best time to catch animals is at dusk. Hunter/Gatherers would catch shellfish at night, sleep around dawn, eat a big omega breakfast, then go looking for fruit in the morning, then sleep around midday after their big carb hit and insulin spike, then go hunting in the evenings, eat their fatty meaty catch then fall asleep, to wake up around midnight to go fishing again.
That's how the story works out in my head at least, of course if I read a better story than that I might be inclined to change my mind, but so far it makes sense from what I understand about our circadian rhythm.
And then of course we started eating cooked starches and drinking dairy/grain ferments, and we went downhill from there... So really, I don't think their story is too off the truth, of course we still stuck to water-sources as we adapted to starches and milk and other vegetarian cuisine , so we never actually stopped eating shellfish and fish.

Interesting theory. Can I quote you on my health blog?

Sure, goodsamaritan, no problem. I basically eat and sleep like that story now. I eat seafood for breakfast, walk, fruit/veg for lunch, nap, resistance exercise, game/offal for dinner, sleep, get up fast either swim/wade/walk/sex, sleep then do it all again :)

there may have also been environmental reasons for why there was a shift in diet, such as elevated water temperatures causing "red tide" or something similar. i think we fail to realize that evolution is not always the same as choice
