Hi Ken, 
I must have missed something. Did someone try to censor your posts? As for
your concerns for us and our net acidity, I'd like to offer the comments
below: 

I'm a big fan of Loren Cordain's work. However, that doesn't mean that I
accept his views without thought. Frankly, without clinical trials, most of
the work in the realm of base/acid balance that I've seen is speculative,
anecdotal, or structured to render a pre-conceived outcome. There are some
exceptions. For instance, Michael N. Marsh did some work with celiac
patients measuring their calcium intake, absorption, and excretion. He
stated: "More sophisticated metabolic studies have now established that the
overall negative balance in gluten sensitivity is the result of high rates
of endogenously secreted calcium, rather than to actual failure of calcium
absorption." (1) Although Marsh attributes this negative balance to vitamin
D deficiency, bone minerals used to buffer grain-induced acidity might
contribute to mineral losses. 

Two of the studies cited by Cordain in that interview report that increased
protein intake can increase urinary excretion of acid, so the argument is
less than compelling. I do not doubt that excessive lean meat might impact
on bone density through alteration of acid/base balance. I do, however,
doubt that fats induce increased acidity. 

Further, Cordain's focus on wild game muscle meat is, I think, a limited
perspective. Burgeoning bodies of genetic evidence now indicate that the
spread of modern humans across the globe took place primarily along
sea-shores. The evidence also suggests that both in Africa and our expansion
out of Africa was dominated by beach-combing food gathering and hunting. I
do not doubt that our forebears ate available land animals but the evidence
suggests that the mainstay of their diets throughout much of the Paleolithic
and Mesolithic was seafood, fish, and sea mammals, along with edible plants
and bugs.    

The fact that Cordain has found that muscle meats from contemporary, wild,
ruminant game animals contain specific fat profiles that are problematic for
human health suggests that: 1. we evolved eating some other kind of food; 2.
The fat composition of this kind of meat has changed through extinction of
the large ruminants that carried much more fats, or; 3. current beliefs
about healthy fat profiles are flawed. 

As indicated above, I think that beachcombing provided much more of our
foods, for much longer than hunting game animals. Further, I believe that
the land animals we did hunt provided us with much more fats.  I'm also a
fan of Gary Taubes, which means that I think that current beliefs about
healthy fat profiles are woefully misguided.

Suddenly there are no posts on "Paleo Diet offers the net-base balance
needed," which was proving to be an interesting if provocative post?  The
questions have not been adequately answered regarding acid/alkaline diet
philosophy. If Cordian is right, you folks could be damaging your health as
you age, and that's not something to censor.
