We don't eat non-kosher foods because the Torah forbids them.
Many Jews and non-Jews try to rationalize the prohibitions (i.e. prohibition of pork to prevent trichinosis) but there is no stated reason for the regulations in either the Torah or Rabbinical literature.
The Torah-commentaries do incidentally mention various benefits of observing the mitzvot (Torah-commands), but these are seen as ancillary results, not reasons. While there is some merit to keeping the mitzvot for personal interest (Talmud, Sanhedrin 105b), one's intention should be to do them because they are the will of God (ibid).
