Kevin,
I passed your note and a few others on to Terry Giles, and this is his
response to me ( *note---the asshole he refers to is not you:-)....there
have been a few responses to me that were not the reasoned questions like
you raise...  -

>Dan - The biggest problem with these types of arguments is ONE - You have
assholes making stupid statements like "he doesn't know anything" - why is
this - because I or we don't agree with his position - that's a little
shallow.  TWO - I can find research to support BOTH sides of the argument -
so this means no matter what side you take - there is published research
supporting both positions.......it comes down to a matter of "lets talk
reality - fact" let's look at results and how things happen in the real
world - not in fantasy land - where each side supports his or her position
with "published" reports, tests and the like. Doctors no more agree on
nutrition - the basis of nutrition or anything to do with nutrition - then
the state can build a road in a week. It will never be a clear cut issue. As
far as Mr. Microbiologist goes - I know what chemical and molecular
structures look like on paper and I understand the theory behind the
biochemical and biophysical reactions and responses - I also know that just
because it looks one way on paper or in theory - doesn't mean it works. On
paper a 747 jet isn't supposed to fly. And on paper - certain nutritional
substances are supposed to do things they don't - we in the real world learn
how to harness and utilize foods and nutritional supplements to accomplish
many things - some things we accomplish are "by-products" or controlled side
effects if you will of an item that SHOULD do one thing - but is manipulated
to do ANOTHER. So we and they can argue until they are blue in the face - I
just know what I have and what hundreds of people have achieved under my
"unknowing" practices - so in short - if they don't agree - fine - so be
it -




Kevin, and others with vegetarian mind set-----believe what you want. I will
waist  no more time argueing this.
Regards,
Dan
