Really?  By whom?  If you really think that's what I was arguing then I
encourage you to re-read what I wrote.  I was defending vegetarianism yes.
I don't recall anyone on this list making a remark that it is better than
any other diet.

The human body is not designed for it long term.


Evidence please!

Iodized salt is also a good source of iodine in first world countries.  We
need only trace amounts anyway.  I think the comment about B12 is probably
the best counter argument I've seen you come up with.  But, even so it's
possible to get enough B12 with a balanced diet.

If you want to go the route of evolutionary arguments then we should note
that there is pretty good evidence to support the idea that our ancestors
were vegetarians first and later became omnivores.  Also, I thought that our
ancestors lived in trees in Africa first and then came down from the trees
as northern Africa turn into grasslands.  Either way, we're not trying to
feed our evolutionary forefathers.  I thought the discussion was modern man
and modern agriculture and global trends.  If you're not making an
evolutionary argument then this point is lost on me.

Well, then kudos to those ranchers, farmers and wild grazers.

Are you in the camp that believes that plant based estrogen in soy destroys
the brains of men?  Better yet, what is the problem with eating soy for
extended periods?

Again, I would like to refer you to endurance athletes for examples of
people who can make these lifestyles work.  Endurance sports are very
demanding on the body.  They require higher amounts of protein for example.

I'd just like to reiterate that I think this is a good way to treat a
symptom but that we should treat the cause as well.

I don't have anything to add here.

Yeah, ruminants are quite useful to us.  But, feeding them on corn as we
mainly do here in the US is bad.  It's bad for them which translate to bad
for us as their consumers.  And growing all that corn has the other bad side
effects I mentioned when this thread started.  One of my main points remains
that the extreme to which we are doing the industrial agriculture is the
primary problem.  A partial solution is to eat lower on the food chain and
thus reduce the impact.

Given the number of healthy adults with a pure vegan diet the risk here must
be small and manageable.

I'd like to read more about this if you can produce the article you got the
information from.
