Eating in place of the Korbonos

It is well known that Tefilah is in place of the Korbonos today, but Achilah (eating) is also in place of the Korbonos.  Just like a person davens 3 times a day, they eat three times a day.  If a person eats correctly, for the needs of their body and not for desire, then a person is bringing a Korbon to Hashem.
