>denatured---does this mean processed in someway?

denatured  food is a food that could not been found in that state in
nature.
or require some artifices to become available ( like milk requiring
the
domestication of wilds animals) so denaturation goes from the minor
ones
like grating or juicing to cooked or worse refined etc... Grated
carrots are
allready denatured for example ( the level of  oxydation that occur is
very
different from  what is happening to the carrots nutrients when
released in
the mouth and immediatly mixed with saliva by chewing them.
The question to ask is :could i find this food in that state in
nature? .
the concept is quite straight forward but can be subject to extensions
like:
Is domestication of plants and animals changed the nature of the food
to the
point where the possibility of eating it instinctively is
compromised.?
etc...

>instinctive eating--  is this eating whatever you want in a paleo sense?

Not at all , and that is the point It is not about eating what you
want but
what you need. The most obvious regulation system that nature gave us
is in
the senses of taste and smell.
So the goal is to bypass the judgements made onto food and let the
more
primitive brain to decide for us. The trick,  being,  that the food
have to
be as undenatured as possible for the  instinctive regulation system
to work
at its optimum.  Concretly it means smelling the food ,one by one and
choosing the most attractive, the one that make you salivate. And once
the
sense of taste is indicating a lost in flavor and aroma while chewing
it ,
or if you wait longer,  when the taste becomes unpleasant>, it is time
to
stop.
