Now you are simply just fkg .. lying .. the body has methods to

I never said metabolic handling of the various minerals is equivalent,
I said human physiology has evolved to store every mineral in various
amounts in order to fuel metabolic processes. Of course, iron is
problematic for those with hemochromotosis, people receiving
transfusion therapy, and possibly individuals who oversupplement iron
(especially if they also take large amounts of vitamin C, a synergist
to iron uptake.) It is clearly possible that those consuming excessive
amounts of animal protein on a daily basis may also exceed their
optimal iron stores, but this effect would be highly variable among
individuals. If you can reference any study showing the occurence of
iron overload (serum ferritin exceeding 500 ng/ml [normal is 40-160]),
in non-vegetarians regardless of the amounts of meat consumed, I would
love to see it.

Yes, I get it, but where is the evidence this occurs in the average
meat eater? Some well-documented studies have shown that iron
DEFICIENCY is the most prevalent nutritional disease worldwide, and my
theory is that this relates, in part, to a lack of vitamin C in the
human diet. Vitamin C is an important synergist to iron.

Too much iron [cannot be] ...CAUSED .. by .. substances which IMPEDE
THE ABSORPTION .. of.. iron .."

This is where you need to pay attention. Iron overload is a reference
to excess iron in tissue. This, again, is a unique problem for
certain individuals but not the average human. By contrast, FREE iron
is a reference to the amount of iron which fails to metabolize and
therefore remains in serum (blood), meaning it never has the
opportunity to enter the "accumulation" state you like to talk about.
BOTH of these iron states are a problem and can cause illness in Man.
Biologically, these iron states occur for very different reasons, as
well.

-- you said --
Phytic acid DOES NOT .. impair .. anything ..
 
Phytic acid binds iron and prevents its metabolization. I never used
the word "impair."

[The] vegetarian diet has been shown to be .. healthy .. actually
..HEALTHIER..

lower antioxidant levels .. IN .. meat eaters ..

Higher antioxidant levels is certainly a good thing, and lower meat
consumption may translate to a higher intake of green foods. But
these measurements alone do not necessarily mean "healthier." Without
adequate protein intake, the optimal stasis between anabolic and
catabolic processes is not maintained. In vegetarians, this
frequently takes the form of an excessive catabolic (muscle wasting)
state.

-- you said --

People are healthy when they avoid processed foods, synthetic
additives, steroids, chemicals, pesticides, and other harmful man-made
agents. A garden is always a great way to improve ones diet.
