i don't think there is any reason why to exclude roots just don't makes it a
staple .

olives are traditionally crushed with stones natuirally we will east only
the flesh of the olive ,but in the oil a big percentage is coming from the
pit that is very very bitter.seeds require more intense technology than
olives that you could almost crush by hand and extract some oil. the thing
is that our ancestors will have not bother extracting oil as it is so much
work and end up with less than when you started . agriculturists can afford
this kind of thing with cultivated plants not a hunter gatherer.
it is my opinion than exposing any oil to the oxygene when extracting is a
waste .

i think also that omegas 3 in canned are completelly denatured because of
the high heat and pressure involved in the process.

not so much because the narrow variety of foods available  in pastoralisme .
nomads typicaly choose grass environment and don't have to bother  looking
for diversity .the modern paleo eaters might fall into a pastoralism type
diet because of the narrow choices in commercialised foods.

milk is poor palliatif for lack of good ressources  in animal foods .
