Well, it WAS available, especially in the easyer  to hunt
calves. Since calves live ON milk the stomaches should mostly include
milk parts (coagulated= fresh cheese). That's a difference to
tomatoes, paprica, corn (new world food) and fish.
These food items *are* inexistent as food
in paleolithic times, aren't they?.

I don't speak about the amounts found. But stomach contents should
be comparable in volume to brain or marrow, for example.

That's the question, what amounts of food for a how long time
are necessary to cause an adaption.
If a food item contains some ingredient with the intention to
protect the origination plant or animal by its toxic properties,
then clearly an adaption time is necessary.
Then additional enzymatic systems must be built up by the body
to cope with that stuff.
Example: lectins.. fruit acids.. antitrypsin in legumes..
solanin in potatoes.. "hot" and spicy items..
Some protective stuffs can be handled by human body, or are
even welcome (like the spices').
Some newer -non paleo-  stuff (solanin, coffeine..) may or will cause
health problems.
Heat processing (by fire) is and was a main human digestion and
toxin lowering technology.

Fortunately for hunters, meat normaly protects itself by
having claws or teeth , or by running away :-)

Eggs are high allergenic. But i think they must have been eaten
for a very long time (paleo) because africa is populated with birds.
I'd be interested to hear what *your* misgivings about eggs are
(i dont want them too).
Egg white contains a protective chemical (hindering protein

digestion).

ahm back to milk...
We are mammals - we *are* intended to get milk
by nature in the first years.
So we have the enzymatic ability to digest it.
Common opinion was, that we (some of us) loose our digestion
ability by the inability to digest lactose in the adult years.
The article quoted by Dean Esmay gives a hint that it may be

different.
Lactose may be *intended* (by nature) not to be digested, but to aid
a proper symbiontic population in the colon and intestine.
