There's this bizarre notion that if we can replicate the diet of our hunter/gatherer forebears (I wonder if Goldilocks is included in that unusually large bear figure), we can live forever.

Yet none of those guys is alive today, as far as I'm aware. And for man to have had enough evolutionary advantage to survive, he needn't have been capable of immortality, merely the ability to live long enough to procreate and nurture the next generation of diers.

Yet, I will likely today be going to the gym, just like Cro-Magnon man as he weathered the ice age all those months ago.

But, you know, that's completely different.

It's not the grasping that is the search for man's perfect diet. (Which, by the way, is based in the word "die".)
