IIRC NASA found that the best defense against bone problems is the right
electro-magnetic field in the spacecraft to counter the (calcium?) loss
from extended time in zero gravity.
An interesting report from geology is that the magnetic field of the
planet is much weaker than it was thousands of years ago.

IMHO zero carb is a best-fit healing way, not necessarily a proven way 
of eating for all time.

Likely so, but we have problems making a varied diet work. One reason is 
the language, for instance successful modern hunters don't "hunt" to get 
food. They sit. When the prey appears, they poke, not with a sharp stick 
because they are relatively slow, weak and sickly compared to paleo 
ancestors but with a bullet.
So lurking and poking is what "hunting" has always been, IMO.

I once saw a drawing of relative behaviour of the sexes in a shopping 
mall, where the female path was drawn as long and convoluted, while the 
male path was short and direct.
Aha! thought I, this is gathering compared to hunting. Gatherers might 
not find anything useful but they still seek and apparently enjoy doing so.
So it follows that gathering behaviour would get veggies and/or small 
animals; if we can agree that this is instinctive it means that some 
plant-source food is/has been important to survival.

There is a teaser in the legend of Gilgamesh where the king gets 
Gilgamesh (the archtypical paleoman (my guess)) to help the king look 
for a plant which would give him eternal life.
Better he should have asked Gilgamesh's wife, then he might have found 
it, and we might find it too.

  Agreed, but first, I think, we need to dream up the right questions.
