Really, if you want to be vegetarian, fine, there are reasons to be.
You can do it and be healthy. (I dunno about fruitarian, however) But
claiming it's natural for us is not true. We do not have the teeth and
digestive tract of fruti -only eaters; we hav ethe teeth and digestive
tract of omnivores.

True, the definition of a fruitarian is not "fruit only" but over 50%
fruit, so a fruitarian diet would include other foods.

I showed teeth and digestive tracts of monkeys in my first post, are
you commenting on that. Just for kicks, which of the four digestive
systems that were shown looks most like a humans:http://www.google.com/books?id=PgiGPYeVN0sC&pg=PA217&dq=&sig=ACfU3U1s...


Actually, I was simply commenting on humans.

From
http://www.beyondveg.com/billings-t/comp-anat/comp-anat-6c.shtml

"Human gut small compared to apes. Observing that human gut
proportions are different from those found in carnivores, herbivores,
swine (an omnivore), and even most other primates, including the
anthropoid apes, Milton [1987, p. 101] notes that "...the size of the
human gut relative to body mass is small in comparison with other
anthropoids (R.D. Martin, pers. comm.)." Milton [1987] includes a
table (3.2, p. 99) that compares the relative volumes of the different
parts of the gut for selected hominid species. The table shows the
stomach at 10-24% of total gut volume in humans, while for orangs and
chimps it is 17-20%. The small intestine is 56-67% of total gut volume
in humans, 23-28% in orangs and chimps. And the colon is 17-23% of
total gut volume in humans, while it is 52-54% in orangs and chimps.
The percentages quoted in the preceding sentence are unscaled, i.e.
are not scaled for inter-specific differences in body size. Despite
this, the figures are useful to compare patterns of gut proportions,
and the general pattern is clear: humans have "large" intestines,
while chimps and orangs have "large" colons.

Additionally, Milton [1987] discusses two primates whose gut
proportions appear to roughly match those of humans:

* Capuchin monkey (Cebus species) which has a high-quality diet of
sweet fruits, oily seeds, and (40-50% by feeding time) animal foods--
invertebrates (insects) and small vertebrates [Milton 1987, pp.
102-103].

* The savanna baboon (Papio papio) is a selective feeder who
searches for high-quality, nutritious foods. [Caution--remark is based
on only one measured specimen for gut proportions.]"

Strangely, altho we are most closely related to the chimps and
bonobos, and the gorillas beyand them, our GI tract more closely
resembles the Capuchin. Could it be because they eat much like our
paleolithic ancestors did?
